1.3 Safety precautions

! WARNING

The bowl of SELFJECTOR produces a large centrifugal force when it rotates. Wrong handling is very

dangerous. Pay utmost attention according to the manual for operation, disassembly, reassembly,

maintenance, checkup, etc. Use of non-genuine parts might damage SELFJECTOR or impair human

safety. Be sure to employ genuine parts.

Perfectly assemble.

Many points of SELFJECTOR are connected by screws. When assembling, make sure tightening is

complete. Running with poor tightening is very dangerous. Doubly make sure of secure tightening

particularly of:

(A) Bowl nut

(B) Disc nut

(C) Cap nut of Vertical shaft

(D) Set bolt of Frame cover

(E) Lock nut (hexagon) of Inlet pipe

Be sure that tally marks of the bowl and other so marked parts are aligned.

If the tally mark is excessively mis-aligned when the Bowl nut is tightened, contact our company or

service agency.

Immediately stop if vibration is excessive.

Vibration of SELFJECTOR is caused by unbalance, ship oscillation,

SELFJECTOR installation, etc. If the vibration is excessive, immediately

stop SELFJECTOR without discharging sludge.

Then, check for the cause and take necessary corrective action to ensure

safety before restarting SELFJECTOR.

To be more specific, if the vibration at the point A of Fig. 1-1 exceeds

100 μm (peak to peak) at rated speed, stop SELFJECTOR.

Even if readings are below 100 μm, continuous cruising ship vibrations

4-5 times higher than registered when external vibrating forces are small,

such as when the main engine is not in operation, could adversely affect

the durability of SELFJECTOR. In such case, stop SELFJECTOR

immediately. Then, check for the cause and take necessary corrective

action to ensure safety before restarting SELFJECTOR as described

above.

Fig. 1-1


! WARNING

Make sure of complete stoppage before loosening each section.

Make sure the bowl has complete stopped rotating before loosening or disassembling each section.

Whether completely stopped or not can be checked at the motor fan or Gear pump and Horizontal shaft

connecting section (Safety joint).

Take care in handling the parts.

SELFJECTOR is a precision machine. Handle it attentively away from impact and high temperature.

Particularly never heat the bowl parts (Bowl body, Bowl hood, etc.) by open flame nor weld them.

Beware of corrosion and erosion.

Periodically check whether any damage is produced by corrosion or erosion.

For details, contact our company or service agency.

Others

1. Before disassembling, turn off the starter.

2. Before treating a treating liquid other than specified initially, contact our company or service

agency.

3. The bowl is factory balanced. Never interchange bowl parts Disc (1) even within the same model.

For ambiguous points in the instruction manual, contact our company or

service agency.

2 Component Functions of the Purifying System

2.1 Automatic control panel

Automatic start : (AUTO START)

Each automatic control panel has an "AUTO. START" push button. Pressing this push button after the

purifier has reached its rated speed starts the predetermined sequence of automatic running.

Automatic stop : (AUTO STOP)

Each automatic control panel has an "AUTO. STOP" push button is incorporated in each of the

automatic control panels. Pressing this push button during running switches the feed valve to the

bypass line. The sequence of water replacement and sludge discharge follows, then the automatic

running circuit is cut off and the oil purifier motor is stopped.

Emergency stop : (EM'CY STOP)

Each automatic control panel has an "EM'CY STOP" push button. Pressing this push button during

running cuts off the automatic running circuit immediately and switches the feed valve to the bypass line,

then the oil purifier motor is stopped without sludge discharging.

Discharge test : (DIS-T)

Each automatic control panel has a "DIS-T" push button. When the oil purifier is in automatic

running and in the feeding, pressing this push button forces the discharge interval timer to be timed up,

sludge is discharged.


2.2 Multi-Monitor (MM)

The Multi-Monitor forms an integrated detection system with the following digital displays and detectors.

The Multi-Monitor is available in three types (MM-1, MM-2 and MM-3) for selective use according to the

automatic system configuration.

Digital displays Function (Flow rate, temperature, pressure, rotation number*1 and other LED)

: MM-1, MM-2, MM-3

Leakage Monitor Function (LM) : MM-1, MM-2 and MM3

Discharge Detector Function (DD) : MM-2, MM-3

Water Detector Function (WD) : MM-3

NOTE1: MM-1 has no rotation number display function.


2.2.1 Display Function

Data necessary for daily monitoring of operational status are digitally indicated through seven

segment LEDs.

Indicated data pertain to flow rate, temperature, pressure, rotation number, circulation line pressure

(G-HIDENS spec.), though those vary with different models of the Multi-Monitor.

NOTE

Since the flow rate displayed on Multi-Monitor(MM) is the value which converted pressure into

flow rate , please use it as a guideline.

When you always use a gear pump under 30% or less of its rated capacity, we recommend using

the small orifice (option) under 1 rank.

2.2.2 Leakage Monitor Function (LM)

The Leakage Monitor is a protective device that detects the treated oil leaking from the sludge

outlet or heavy liquid outlet of the SELFJECTOR by means of a pressure sensor, thereby

minimizing the loss of treated oil.

The pressure sensor is installed on the SELFJECTOR bracket (at the light liquid outlet) and

constantly monitors pressure during feeding. When a pressure drop occurs due to a leakage, the

pressure sensor detects it and the pressure sensor output is sent as a "Leakage" signal to the

automatic control panel via the Multi-Monitor.

2.2.3 Discharge Detector (DD)

The Discharge Detector is a protective device that monitors sludge discharge from the

SELFJECTOR and detects a discharge failure as the "No-discharge" status.

Normal sludge discharge is accompanied by a drop in horizontal shaft rotation speed to the preset

level. Relying on this characteristic, the Discharge Detector constantly monitors the horizontal shaft

rotation speed by means of a proximity sensor. If the horizontal shaft rotation speed fails to fall at

sludge discharge, a "No-discharge" signal is delivered to the automatic control panel via the

Multi-Monitor.

As a self-diagnosis function, "No-discharge" LED (red) is illuminated in response to a shaft rotation

number beyond 2500 rpm or an instable proximity switch input signal.

In addition to the sludge discharge monitoring function, the automatic GSH-1 system combined

with Multi-Monitor MM-3 has a partial discharge detection function to indicate whether or not sludge

discharge is optimal for partial discharge adjustment.

2.2.4 Water Detector Function (WD)

The Water Detector is an integral device that is used for the G-HIDENS system (for clarifier

operation) that constantly monitors the changing levels of separated water in the bowl by means of

a pressure sensor installed in the circulation line.

Pressure in the circulation line falls when separated water in the bowl has reached a predetermined

level. The Water Detector in the G-HIDENS system detects this pressure change by means of the

pressure sensor and effects partial discharge or total discharge with sludge, whereby the inside of

the bowl is always maintained in a normal separating condition.

The Water Detector is used only in the automatic GSH-1 system configuration.

2.3 Gear pump

This is installed on the bearing housing (3) of

the purifier and connected to the horizontal

shaft via a safety joint. It is driven by the motor

of the purifier. (Refer to Fig. 2-4)

The gear pump supplies feed liquid to the

purifier.

The gear pump can be selected according to

its treating capacity.

NOTE1:In case of 60Hz

2.4 Safety joint

This is mounted on the end of the horizontal shaft for transmitting the motor power to the pump.

(Refer to Fig. 2-4)

This will be automatically disconnected for protecting the gear pump, if it is subjected to an

excessive overload due to sticking foreign matters, etc.

2.5 Plug (sludge outlet)

! WARNING

Do not open this plug absolutely during a sludge discharge process.

These are inserted in the sludge chute of the purifier main body. (Refer to Fig. 2-4)

When it becomes necessary to check the internal state of the frame, unplugged.

Fig. 2-4

Ｒ（


2.6 Operating water solenoid valves unit

There are a triple solenoid valves unit for total discharge and a quadruple solenoid valves unit for

both total and partial discharge available for control of operating water. Each unit has a reducing

valve upstream of the solenoid valves. (Refer to Fig. 2-5)

The solenoid valves unit for operating water is built in the oil purifier.

The solenoid valves unit controls the feed of operating water for opening bowl, operating water for

closing bowl, sealing water and replacement water.

Each solenoid valves is actuated by input signals from the automatic control panel to effect and

stop the feed of operating water to the oil purifier.

2.7 3-way Cylinder Valve

This is a pneumatically operated cross valve mounted on the purifier inlet pipe. (Refer to Fig. 2-5)

It supplies feed liquid to the purifier.

When discharging sludge, it returns the oil from the by-lass pipe to the tank by switching the valve

position.

2.8 3-way Solenoid Valve

This is attached on the air piping to the 3-way cylinder valve.(Refer to Fig. 2-5)

The 3-way solenoid valve changes its position according to signals from the control panel and

actuates the 3-way cylinder valve.

2.9 Oil Heater

This is installed on the way between the gear pump and the purifier.(Refer to Fig. 2-5)

It heats the feed liquid supplied from the gear pump to an optimal treating temperature.

There are two types of oil heater; steam type and electric.

2.10 Oil strainer

This is installed upstream of the oil purifier to remove residual solids in the feed liquid. (Refer to Fig.

2-5)

2.11 Flow control valve

This is installed to control the feed rate to the oil purifier. (Refer to Fig. 2-5)

2.12 Pressure Control Valve (needle valve)

This is installed in the light liquid outlet line of the oil purifier. (Refer to Fig. 2-5)

This valve is used to control the light liquid outlet pressure to 0.15 MPa {1.5 kgf/cm2} (standard

value).

NOTE

The light liquid outlet pressure is critical in ensuring that the Leakage Monitor Function (LM) of

the Multi-Monitor acts correctly.

Improper pressure adjustment could result in a LM alarm output. For pressure adjustment

during running, refer to "Leakage Monitor Function (LM)" in the Operation Manual 2.

Draw a dotted line that is parallel to the line of 40 mm2/sec at 50℃ and passes an intersection (point A)

between a horizontal line of 45 mm2/sec and a vertical line of 50℃. From the intersection between this

line and a horizontal line of 24 mm2/sec draw a line perpendicular to the horizontal axis, then read the

temperature falling on the foot; that is 67℃.

Thus the treating temperature of this heavy oil should be 67℃.

3.3 Gravity Disc

In the purifier operation it is necessary to hold the interface between the light liquid and heavy liquid in

the bowl within a definite rage. Therefore, the SELFJECTOR can employ gravity discs of various inside

diameters such that the outlet diameter of the heavy liquid side can be altered for interface position

adjustment. One gravity disc having a larger inside diameter, if incorporated, moves the interface

outward, and another disc having a smaller inside diameter moves the interface inward.

Selection of an appropriate gravity disc is one of the most important subjects for oil treatment with the

SELFJECTOR. Exercise sufficient care for this selection to avoid unintended purifier operation.

NOTE

At the delivery of a SELFJECTOR, the gravity disc and bowl come in each package.

Select an appropriate gravity disc and assemble it in the bowl according to Section 3.3.2

"Gravity Disc Selection Procedure".

3.3.1 Supplied gravity discs

! CAUTION

Before treating a different type and nature of oil, select a suitable gravity disc having an

inside diameter that fits the gravity of the treated oil.

Running the purifier with a gravity disc of incorrect diameter may cause oil outflow to the

heavy liquid side and water circulation over the light liquid side.

Table 3-3 shows the supplied standard gravity discs for the purifier operation and Table 3-4 shows the

gravity discs for the G-HIDENS operation.

NOTE

Actually supplied gravity discs differ for types of the treated oil. For detail refer to the attached

document and drawing.

3.3.2.2 G-HIDENS operation

For G-HIDENS operation, use dedicated gravity discs for G-HIDENS. (See Table 3-4)

NOTE

In the case of G-HIDENS operation, there is no need to change gravity discs according to

operating parameters such as gravity of treated oil.

For HIDENS purifier operation, select suitable gravity discs in accordance with the gravity disc selection

procedure for purifier operation described above.


3.3.2.3 Gravity disc selection examples

3.4 Lubrication Oil

Lubrication oil in the gear case lubricates each

bearing of the vertical and horizontal shafts as well

as the acceleration gear.

The available lubrication method includes the oil

bath and splash lubrication by a spiral gear.

As the maintenance performance of the lubrication

oil seriously affects the life of each power

transmission unit, sufficient care should be

exercised on its handling.

For this lubrication, remove the gear cover or

lubrication plug attached on the gear cover.

! CAUTION

Before supplying the lubrication oil, be sure to stop the SELFJECTOR. The oil becomes very hot

during operation. To avoid the risk of the oil being scattered around to burn operator's hand or

hurt his eyes, do not remove the plug or gear cover when the SELFJECTOR is in operation.

3.4.1 Oil quantity

! CAUTION

Oil quantity should be checked with the SELFJECTOR being held

horizontally.

Refilling the lubrication oil as to exceed the upper red line (H) may

cause additives contained in the lubrication oil to deposit into sludge,

which can adversely affect the lubrication effect. Take sufficient care

not to exceed the upper red line (H).

Refer to

Table 3-6 for appropriate oil quantities. Refill the oil up until the red

line (H) on the oil gauge as shown in Fig. 3-31.

During operation make sure that the oil level falls in-between the red lines (H) and (L).

3.5 Sludge Discharge Interval

! CAUTION

Too long sludge discharge intervals may cause defective separation and mechanical damage on

the unit.

The optimum sludge discharge interval varies with the operation method and nature of the treated oil,

etc., which makes it hard to be uniformly determined.

Too long intervals may accelerate the contamination inside the bowl and result in sludge deposition,

whilst too short intervals may reduce the operation efficiency.

NOTE

To determine an optimal discharge interval, it is a recommended practice to perform a test run

under practical conditions for a certain length of time and find an interval commensurate to

sludge concentration in the treated oil while watching the internal state of the bowl partial

accumulation of sludge, contamination of disc(1), etc.

3.5.1 Discharge Interval (Total discharge)

The general discharge intervals and amount of sludge discharge for the treatment of fuel and lubricating

oils by the manual type GAP-11 and automatic types GBC-1 and GSH-1 are as shown in Table 3-8 and

Table 3-9, respectively.

3.5.2 Discharge Interval (HIDENS specification)

For reference, Table 3-10 shows the general discharge intervals where a fuel oil or lubricating oil is

treated in automatic specification GSH-1.

The automatic specification GSH-1 discharges sludge in the total discharge and separated water in the

partial discharge. In some cases, however, total discharge of separated water with sludge takes place,

depending on the amount of time spent for water detection. The lubricating oil treatment can include

post-total discharge the bowl washing process at a certain rate. The sludge discharge rates for different

types are generally as shown in Table 3-9, though they vary with the frequency of water detection.

! CAUTION

Operate the lubricating oil purifier continuously as long as possible.

Should the purifier be forced to stop for the reasons below, operate it for approximately 12

hours with sludge discharged at 10 to 20 minutes intervals before setting for discharge at

standard intervals after taking into consideration of the system oil at the time of normal

operation.

Restarting the engine and purifier after stopping

them in the anchorage or dock.(This is because

the sludge density increases at the inside

3.6 Operating Water

The SELFJECTOR requires;

Operating water for opening/closing bowl,

Sealing water,

Replacement water,

Regulating water (when lubricating oil is treated),

Bowl washing water (when lubricating oil is treated).

Normally, pure water is used in all cases. To ensure proper use of the SELFJECTOR, the water

pressure should be correctly set by means of reducing valve for operating water.

Fig. 3-32 Triple Solenoid Valve Unit (GBC-1)

Fig. 3-33 Quadruple Solenoid Valve Unit (GSH-1)


3.6.1 Operating water quality

! CAUTION

When hard water is used, scale will be produced on the inside surface of the water

supplying device, drain nozzle, or solenoid valve, which may cause various troubles.

The harder the water, the more scales on the water supplying device and pilot valve. To

prevent it, the cleaning intervals should be as short as practically possible.

Since the operating water is used for the opening/closing valve of the purifier bowl, its quality should be

pure, transparent and soft water such that it can prevent the valve from scaling or corrosion.

Use that quality of operating water, as follows:

Evaporation remainder 10 mg/L or less

Total hardness 110 mg/L or less : as CaCO3 /L (Hardness 6 dH or less)

pH value 6.5 to 7.5

Salt content 100 mg/L or less: (Cl- 60 mg/L or less)

3.6.2 Setting pressure of operating water

Use the following operation water pressure for each of automatic specifications.

Automatic type Discharge type Set pressure

(Standard value)

Required pressure

Manual, GAP-11

GBC-1, GBC-2 Total discharge 0.3 MPa (3.0 kgf/cm

(0.35 to 0.5 kgf/cm2)

! CAUTION

Where the primary pressure of operating water is lower than 0.2 MPa (2 kgf/cm2), then sludge

discharge efficiency will be decreased. Otherwise a pressure exceeding 0.75 MPa (7.5 kgf/cm2)

may cause the solenoid valve malfunctioning.


To adjust the operating water pressure, use the adjust screw on top of the reducing valve while reading

the valve's pressure gauge. (See Fig. 3-17)

How to pressure adjustment with adjust screw

Turn clockwise: Pressure increases.

Turn counter-clockwise: Pressure decreases.

The reducing valve has been shop-adjusted for optimal water pressure according to manual and

automatic specifications shown in Section 3.6.2.

! CAUTION

When setting or adjusting the operating water pressure during running, use the manual handle

of SV2 while running operating water for bowl closing. When the purifier is not running, perform

this with the operating water inlet tube (Teflon) removed. Otherwise, the operating water could

find its way to the gear case to damage bearings.

NOTE

The pressure of the operating water reducing valve may increase after the SV2 solenoid valve

closes, but this is not an anomaly.


3.6.3 Operating water for opening bowl

The operating water for opening bowl is used to force down the main cylinder to open the bowl, letting

out sludge and water accumulated in the bowl in the "total discharge" or "partial discharge".

In the case of total discharge, the operating water is regulated by the solenoid valve SV1 and

introduced into the bowl opening water pressure chamber via feeding device.

In the case of partial discharge (GSH-1 specification models only), the operating water is regulated

by the solenoid valve SV9 and introduced into the bowl closing water pressure chamber via feeding

device. When the bowl closing water pressure chamber has been filled up, the bowl opening water

overflows into the bowl opening water pressure chamber, depressing the main cylinder to open the

bowl instantly.

3.6.4 Operating water for closing bowl

The operating water for closing bowl is used to force up the main cylinder to close the bowl. The bowl

closing water is regulated by the solenoid valve SV2 and introduced into the bowl closing water

pressure chamber via feeding device. The bowl closing water is introduced intermittently into the bowl

closing water pressure chamber for a predetermined period of time during purifier operation.

! CAUTION

Where the primary pressure of operating water is lower than 0.2 MPa (2.0 kgf/cm2), the bowl

closing failure could occur.

3.6.5 Quantity of sealing water/regulating water and replacement water, washing water

! CAUTION

If the sealing water and replacement water are not adequate in quantity;

Oil loss during sludge discharge will increase,

Water circulates over the light liquid side, or

Oil flows out from the heavy liquid side.

Therefore, be sure to set correct quantities of these waters.

Sealing water is used to form a water phase within the bowl prior to performing a purifier-run and prevent feed liquid from flowing out of the heavy liquid side when it is supplied. On the other hand, replacement water is used to collect oils in the bowl before discharging sludge so that the oil loss can be minimized. The quantities of sealing water and replacement water required by different models shown below, respectively.

3.6.6 Quantities of washing water

In the case of lubricating oil purifier, washing water is introduced into the bowl to clean the inside at

predetermined intervals of sludge discharge. Solids in the bowl are removed with washing water in total

discharge. The quantities of washing water required by different models are as shown below.

3.7 Partial Discharge Setting/Adjustment (GSH-1)

Partial discharge (amount of sludge) adjustment can be accomplished through pressure control by the

reducing valve for operating water. The Multi-Monitor (MM-3) tells whether or not partial discharge is

optimal.

3.7.1 Setting/adjustment of partial discharge

1. Set the timer (T011) of the control panel to 0.6 sec.

2. Set the reducing valve connected to the solenoid valve unit for secondary pressure at a standard

preset level of 0.25 MPa (2.5 kgf/cm2).

NOTE

The primary pressure of the supply water line should be 0.35 to 0.5 MPa (3.5 to 5.0 kgf/cm2).

The supply water pressure beyond 0.75 MPa (7.5 kgf/cm2) could cause a reducing valve

failure.

To adjust the reducing valve for optimum secondary pressure, use the adjust screw that is exposed if

the seal on top of the valve is removed. Turning the adjust screw as required, set the reducing valve for

desired pressure while reading its pressure gauge. Turning the adjust screw clockwise increases the

secondary pressure and a counter-clockwise turn decreases it.

Proper pressure setting on the reducing valve provides the discharge rates of Table 3-11 eparated 밪Water Discharge Rates (Partial Discharge)? After pressure setting/adjustment, check through the

Multi-Monitor that sludge discharge is optimal in accordance with Section 3.7.2 onitoring Partial 밠Discharge?

Fig. 3-35

Quadruple solenoid valve unit


NOTE

With the reducing valve for operating water set (shop-adjusted) for secondary pressure

at a standard preset level of 0.25 MPa (2.5 kgf/cm2), be sure to ascertain that partial

discharge is optimal by measuring its quantity.

Increasing the reducing valve secondary pressure increases sludge discharge. To

decrease, lower the pressure.

The pressure of the operating water reducing valve may increase after the SV2 solenoid

valve closes, but this is not an anomaly.

3.7.2 Measure of the amount of partial discharge

The measure of the partial discharge is available only in the automatic control (GSH-1) system.

To measure, there are two methods:

1. Continuous measurement during normal operation.

2. One-time measurement for discharge adjustment or check

In this paragraph, the procedure for one-time measurement will be described. Before measure of the

partial discharge, make sure that the sensor is in position by reference to Section 4.3.3 hecking 밅Proximity Switch Position?in this manual.

! CAUTION

Described below is the general procedure for checking the amount of partial discharge. Prior to

starting operation, be sure to refer to Section 5. “Operation“ in this manual. Given instructions

are subject to the SELFJECTOR being ready to start. (The piping had completed for operation).

1. Set the power switches of the starter, automatic control panel and Multi-Monitor to ON in that order.

2. Remove the front cover of the Multi-Monitor and check that all internal switches are in the

designated positions.

1) Check that the 50Hz/60Hz selector switch is in the position of power frequency for the

SELFJECTOR. (See Fig. 3-36)

2) Set the DD alarm output switch to OFF. (See Fig. 3-36)

3) Set the Partial ON/OFF switch to OFF. (See Fig. 3-36)

NOTE

Each model of the SELFJECTOR has a different range of optical discharge.

Correct measurement cannot be performed without proper settings. (Refer to Section 4.1.2)

3. Start the SELFJECTOR in accordance to the start-up procedure described in Section 5.

peration?밢4. Ascertain that the SELFJECTOR has entered into purifier operation. Purifier operation is started in

response command signals received by the Multi-Monitor from the automatic control panel, when

the confirmation LED for input signal "Feeding"(green) in the Multi-Monitor and the otation 밨Display LED?green) on the Multi-Monitor are illuminated.

5. Press the Discharge measurement switch in the Multi-Monitor. The green "Measuring" LED of the

confirmation LED for partial discharge quantity is illuminated. This indication means that the purifier

is ready for measurement. (See Fig. 3-36)


6. Then, press the IS밆 -T?push button on the automatic control panel.

7. The sequence of the automatic control panel proceeds to the "sludge discharge" process and

sludge discharge takes place.

8. The revolution sensor (proximity switch) installed in the purifier picks a drop in horizontal shaft

speed and its output signal equivalent to the quantity of sludge discharge effected is sent to the

Multi-Monitor.

9. The input is indicated through appropriate Partial Discharge LED in the Multi-Monitor; red LED for

"OVER", green LED for "JUST" or red LED for "UNDER". (See Fig. 3-36)

10. If "OVER" LED (red) or "UNDER" LED (red) is illuminated, regulate the secondary pressure of the

reducing valve for operating water (refer to Section 3.7.1 and perform above operations from Step 5

downward to adjust the quantity of discharge until the "JUST" LED (green) is illuminated.

NOTE

A change in reducing valve setting must be followed by discharge tests to have line pressure

stabilized before proceeding to discharge measurement.

3.8 Timer Setup on the Automatic Control Panel

Literally the automatic control panel automatically controls each operation of the SELFJECTOR.

This automatic control panel has incorporated various timers such as to control each solenoid valve, etc.

Correct settings of these timers are the keys to normal and efficient machine operations. The set

periods of these timers will vary depending on the flow rate of the operating water. Consult

Table 3-15 and Table 3-16 for standard settings (guidelines) at each operation mode.

actually and select proper values accordingly.

Fuel oil purifiers have no bowl washing process.


3.8.2 GSH-1 type timer settings (guideline)

Normally, the G-HIDENS type oil purifier discharges sludge in the total discharge mode and separated

water in the partial discharge mode on a command signal from the Multi-Monitor with Water Detector

Function.

For G-HIDENS specification, various timers in the automatic control panel GSH-1 are actuated at the

timings shown in Fig. 3-38 for sludge discharge process and bowl washing process. For action timings

for total discharge timers, see Fig. 3-37. For specific setting requirements for timers in the automatic

control panel GSH-1, refer to the Operation Manual 3.

Fig. 3-38

(Remarks)

Figures in the oblong boxes above denote timer numbers.

If the Water Detector is activated after the lapse of monitoring time (C022), total

discharge of sludge and separated water is effected.

For the timing of total discharge, refer to Section 3.8.1.

In the case of lubricating oil treatment, washing process is effected as many times as

set on the washing counter (C023) after sludge discharge process (total discharge).

For lubricating oil treatment, regulating water feed is added before washing process

and after separated water discharge process (partial discharge).

Timer settings for sealing water and replacement water in the above list are based on the

feed rate at 8 L/min. for SJ10GH to 30GH, at 12 L/min. for SJ50GH to 70GH, at 16 L/min. for

SJ100GH and 120GH and at 18 L/min. for SJ150GH. For practical setting, always measure

the flow rate actually and select proper values accordingly.

Fuel oil purifiers have no regulating water feeding process and bowl washing processes.

! CAUTION

When SJ10GH to 150GH types are used in the total discharge mode (purifier operation), select

an appropriate gravity disc that fits the specific gravity of feed liquid and install it in position.

Then, fully open the shut-off valve and set the Water Detector selector dial to No working

position. (Refer to Section 6.4.2.4 in the Operation Manual 1.) In this case, the setting

values of the timers T002, T003 and C014 refer to Table 3-15 in 3.8.1.1., and set the timers

T011, T012, T013, C022, C026 and C027 to 0. If operated without changing for the setting

values the Leakage Monitor function of the Multi-Monitor is actuated by overflow and

gives an alarm.

To access the memory preset items of the Multi-Monitor, use the function setting switches (SW1 to 4).

Press the function setting switch 4 (SW4: Enter) for 2 seconds and release. A preset item number

appears in the upper seven-segment display with the current preset value indicated in the lower. Keep

pressing the function setting switch 1 (SW1: Select) until the desired preset item number is displayed.

4.1.2.2 Changing Multi-Monitor Memory Preset Value

When it becomes necessary to change a memory preset value, access the number of the item to be

changed through the function setting switch 1 (SW1: Select) and change it by means of the function

setting switch 2 (SW2: Forward) or the function setting switch 3 (SW3: Backward). The preset value

increases or decreases at minimum variable steps predetermined for each preset item. Key in a desired

new value and press the function setting switch 4 (SW4: Enter). The new value is registered in the

memory.

NOTE

Preset values cannot be changed without pressing the function setting switch 4 (SW4).

4.1.2.3 Locking Display

During normal operation, "flow rate" is always indicated in the upper seven-segment LED display, and

"feed liquid temperature"/"light liquid pressure" appears in the lower changing (incrementally) at steps of

5 seconds.

At the start of operation or during operation, when back pressure at the light liquid outlet becomes

necessary to adjust to optimize the Leakage Monitor function of the Multi-Monitor or for other reason,

press the Pressure Display Lock switch on the Multi-Monitor panel once. This freezes the "light liquid

pressure" appearing in the lower seven-segment LED display of the Multi-Monitor. (Flow rate remains

indicated in the upper LED display.) To release the lock to resume the incremental display of pressure,

press the Pressure Display Lock switch again.

NOTE

To lock the display of light liquid pressure only, press the Pressure Display Lock switch at

the left of the Multi-Monitor panel once, and the incremental display is switched to the locked

indication. To resume the incremental display, press this select switch once.

By long pushing the function setting switch 2 and 3 (SW2: Forward, SW3: Backward) at the same time,

the incremental display is switched to the "feed liquid temperature", the "light liquid pressure", the

"revolution number" and the "water pressure" indication by repetition.

The evolution뱑 number is indicated by MM2 (with DD function) and MM-3, the ater pressure? is 뱖indicated by MM-3 only. LEDs (green) on the Multi-Monitor panel are illuminated to confirm the

indications.

By detaching from the function setting switch 2 (SW2: Forward), the display indicates only the "feed

liquid temperature" and the "light liquid pressure" indication by repetition incrementally.

4.2.3 Light Liquid Outlet Pressure Adjustment

To ensure proper functioning of the Leakage Monitor, the

adjustment of light liquid outlet pressure to the light liquid

pressure level preset in the Multi-Monitor (memory preset

item No. 13) through back pressure control valve is required.

Carry out this adjustment as follows.

1. Accomplish pre-operational checks. (Refer to Section

5.1.4 nspections Prior to Running?) 밒2. Switch on the starter, automatic control panel (or alarm

panel) and Multi-Monitor in that order.

3. Set the MM function switch on the automatic control

panel (or alarm panel, starter panel) to ON and the LM

alarm output switch in Multi-Monitor to OFF.

4. Remove the front cover of the Multi-Monitor and check

that all internal switches are in the appropriate positions.

5. Start the oil purifier in accordance with the starting

procedure. Do not start feeding until the rated speed has

been reached.

6. While watching the flow rate display on the Multi-Monitor,

adjust the bypass valve and flow rate control valve for

the feed rate specified for the SELFJECTOR being operated. At the same time, fully open the back

pressure control valve (needle valve) at the light liquid outlet and record the pressure at that point

without fail.

7. Check that the feed liquid temperature is at the preset level through the feed liquid temperature

display on the Multi-Monitor. If lower, pressure drops when the feed liquid reaches the preset

temperature and an alarm is issued in some cases.

8. Press the pressure display lock switch on the panel (or the function setting switch SW1 in the

Multi-Monitor) to freeze the indications of flow rate and light liquid pressure in the upper and lower

seven-segment displays. While reading the light liquid pressure on the Multi-Monitor, accomplish

pressure adjustment to the level preset in the Multi-Monitor (refer to Section 4.2.2) through the

pressure control valve at the light liquid outlet.

9. Make fine adjustment of pressure through the back pressure control valve until the pressure control

LED (yellow) on top of the Multi-Monitor is illuminated. This LED flashes when pressure is within ±15% of the level preset in the Multi-Monitor and is illuminated within ± 3%.

10. After the adjustment of light liquid outlet pressure is completed, press the pressure display lock

switch on the panel (or the function setting switch SW1 in the Multi-Monitor) again to release the

pressure display locked status. Set the MM function switch on the automatic control panel to OFF

and then to ON. After that, the LM alarm output switch in Multi-Monitor to ON. Finally, reinstall the

front cover of the Multi-Monitor.

NOTE

For a period of approximately 20 to 30 seconds after the MM function switch on the automatic

control panel (or the alarm panel or starter) is set to ON from OFF, the LED displays of the

Multi-Monitor remain blank, which is a normal transient phenomenon.

In addition the manual SELFJECTOR version with no alarm panel has the MM function switch

installed on the starter.

Fig. 4-5


! CAUTION

1. The level of "light liquid pressure" preset in the Multi-Monitor is the "measured pressure

recorded in 6" plus LM trigger pressure P (standard value: 0.02 MPa).

Be sure not to set it beyond 0.2 MPa (2.0 kgf/cm2). Setting beyond 0.2 MPa (2.0 kgf/cm

2) may

cause the light liquid to overflow the light liquid chamber. (Refer to Section 4.2.2.)

Standard value for setting "light liquid pressure" is 0.15 MPa (1.5 kgf/cm2) for fuel oil, and is

0.10 MPa (1.0 kgf/cm2) for lubricating oil.

2. The level of "minimum light liquid pressure" preset in the Multi-Monitor should be less than

the "light liquid pressure" mentioned above minus LM trigger pressure P.

This value must be higher than the "measured pressure recorded in 6." If it is equal to or lower

than the recorded level, the Leakage Monitor may fail to detect a leakage of treated oil properly.

Standard value for setting "minimum light liquid pressure" is as follows,

[Minimum light liquid pressure]

= [Light liquid pressure] ? [LM trigger pressure P] ? [0.01 to 0.02] (MPa)

NOTE

Normally, once adjusted at trial run, light liquid outlet pressure requires no further

adjustment unless there are fluctuations in flow rate and temperature.

During daily check, ascertain proper illumination of the pressure control LED (yellow) and

correct indication in the light liquid pressure on the Multi-Monitor.

LM trigger pressure follows up pressure fluctuations due to pulsations during operation.

Even if the pressure control LED (yellow) flashes, therefore, there is no particular need for

pressure adjustment.

4.2.4 Checking Timer Setting after Start of Feeding Always check that the following timer setting is correct after oil feed is started.

Delay timer Ascertain that the time from the start of feeding after sludge discharge to the arrival of discharge side pressure at preset level is shorter than the time preset on the delay timer.

NOTE1

Control fluctuations in the flow rate of feed liquid to the purifier to be within 0.01 MPa in

pressure equivalent.

NOTE2

Control feed liquid temperatures to be within 5% of preset level. Excessive fluctuations

change the feed liquid in viscosity to fluctuate light liquid outlet pressure as a result, possibly

affecting the output of the Leakage Monitor Function of the Multi-Monitor.

4.2.5 Pressure Adjustment after Feeding 1. Set the LM alarm output switch in Multi-Monitor to OFF. 2. Accomplish the steps 8 to 10 in Section 4.2.3 ight Liquid Outlet Pressure Adjustment?밚


NOTE

The Discharge Detector Function (DD) of the Multi-Monitor is a protective device that relies on a

shaft speed drop to work. More specifically, if the horizontal shaft speed is not dropped during

sludge discharge, the detector detects it as a "No-Discharge" status by means of a proximity

switch. If the proximity switch is out of position or the switches are set wrong, a false alarm is

issued.

4.3.1 Setting Up the Discharge Detector Function

For the Discharge Detector Function, the Multi-Monitor is provided with a Partial ON/OFF switch for

monitoring sludge discharge among others, in addition to normal and abnormal speed indicating means.

Fig. 4-6 shows principal switches necessary for setting the Discharge Detector Function.

Fig. 4-6

Selection of power frequency between 50Hz and 60Hz.

Used to select appropriate power frequency for the SELFJECTOR between 50Hz and 60Hz.

Partial ON / OFF switch

Constant monitoring of partial charge for optimal quantity.

Constant monitoring is effected with the switch in ON position and stopped in OFF position. Whether or not partial discharge is optimal is indicated through partial discharge LEDs.

Dischargemeasurementswitch

A push button for effecting one-time measurement of discharged quantity during partial discharge.

Measurement is enabled only when partial ON/OFF switch is in OFF position. Whether or not partial discharge is optimal is indicated through partial discharge LEDs. This switch is mainly used for adjustments at trial run.

（）（）（））


4.3.2 Adjusting the Proximity Switch Position

! CAUTION

The Discharge Detector is precision equipment. Take special cares so that it is not bumped

during handling.

The proximity switch should be retained firmly with the screws.

(The fastening torque should be 60 kg cm or less.)

Make sure that the purifier is completely stopped before checking and adjusting, if

necessary, the installed position of the proximity switch.

Do not use a proximity switch other than supplied with the SELFJECTOR.

The proximity switch is screwed directly in the gear pump housing (horizontal shaft cover where

separate pump is used) and secured with a lock nut. To adjust the installed position of the proximity

switch, loosen the lock nut and set the proximity switch at a distance of 1.0 ± 0.3 mm from the

horizontal shaft. After the adjustment is finished, retighten the lock nut to secure the proximity switch.

(See Fig. 4-7.) The nut tightening torque should be less than 60 kg･cm.

Fig. 4-7


4.3.3 Checking Proximity Switch Position

1. If the proximity switch is in position

The rotation display LED (green) on top of the Multi-Monitor flashes while the oil purifier is in

operation.

The rotation display LED (green) is illuminated when the oil purifier is stopped.

The speed appears in the appropriate seven-segment display.

2. If the proximity switch is out of position -

The trouble display LED (red) on top of the Multi-Monitor is lit when rated speed is reached.

Specifically, this LED is illuminated in either of the following cases.

(i) Input signal to the proximity switch is unstable - probable cause is the proximity switch being out of

position.

(ii) Proximity switch output exceeds 2,500 rpm in speed equivalent - probable cause is a circuit failure.

4.3.3.1 Measuring Proximity Switch Output Voltage

The installed position of the proximity switch can be accurately checked by measuring its output

voltage.

Open then cover of the Multi-Monitor and measure voltage

across between the test pins [GND (black) and [REV (red)]

shown in Fig. 4-8 using a tester.

Table 4-5 shows test pin voltages versus power frequencies

when the proximity switch is in position.

Check the measure voltage reference to the correct voltage.

Table 4-5

Frequency Voltage

60Hz Approx. DC3.5V

50Hz Approx. DC2.9V

NOTE

When the tester reading exceeds DC4V, a circuit failure is suspected. In such case, contact MKK

service shop or us nearest to you.

Note the following points at the start-up.

Subject Measures

Operation sound When an abnormal sound is heard, immediately stop the operation and

inspect the purifier and identify the cause.

Vibration Vibration may temporarily occur just after start-up, however, this is not

an anomaly.

It will be reduced when the rated number of revolution is achieved.

At the rated number of revolution if the vibration is large, immediately stop

the operation and inspect the purifier and identify the cause.

If feed liquid is being supplied, discontinue it and stop the purifier

immediately without sludge discharged.

Start-up time Small-size (SJ10G/GH - SJ30G/GH) and medium and large-size

(SJ50G/GH - SJ150G/GH) purifiers respectively reach their rated speeds in

less than 5 minutes and less than 10 minutes with current stabilized at 50

to 70% of the rated level. If the purifier fails to reach its rated speed despite

the lapse of more than 10 minutes, stop it in accordance with given

stopping procedure and check the friction block.
