1.2 Common sensor introduction
1.2.1 Magnetic switch and application
a. Magnetic switch introduction
Magnetic type approximate switch (in short the magnetic switch) is a non-contact positiondetection switch, this kind of non-contact position detection do not wear and damage
detection object content, the response speed is high. The commonly approximate switch on
production line also has induction type, static capacity type, photoelectric type,etc
approximate switch. Induction type approximate switch used the existence of test metal
objects, static capacitive proximity switch type used the existence of detection metal and
non-metallic objects, magnetic switch used the existence of test magnet; Installations method
have wire leads type, connectors type, connectors relay type; According to the requirements
of the installation place environment, approximate switch can choose shielding type and
non- shielding type.
When magnetic material close to magnetic switch sensor, the sensor act and output switch
signals. In practical applications, in the tested object (such as the piston and cylinder piston
rod) installed on the magnetic material, and in the both end of the outside cylinder cylinder
install a magnetic type approximate switch, it can use the two sensors to mark two limit
position of cylinder sports respectively.

In order to prevent damage the magnetic switch because of wrong connections, usually in the
use of magnetic switch, all series connect the current limiting resistor and the protection
diodes. So even though lead wire polarity reversed, magnetic switch also will not burned,
only the magnetic switch can't work normally.b.The application example of magnetic switch in the DL-MPS901A flexible manufacturing

The figure shows the automatic storage station magnetic switch detection magnet.
c. Installation and debugging of magnetic switch
In the automatic control of production line, can use this signal judge cylinder motion state or
the location, to determine whether the workpiece was launched or whether the cylinder
returned.
1Electrical wiring and inspection
We emphasis on consider the influence which the sensor's size, position, installation way,
wiring craft, cable length and work around environmental factors to sensor work. .
In magnetic switch settings are LED, to display the sensor signal state, for when debugging
and running monitor to observe. When the cylinder piston close, proximity switch output toact, output "1" signal, LED bright; When there is no cylinder piston close, proximity switch
output do not move, output "0" signal, the LED not bright.
2Installation and adjustment of magnetic switch in the cylinder
When magnetic switch and cylinder used together, if not installed reasonable, may make the
cylinder action is not correct. When the cylinder piston move to the magnetic switch, and
close to a distance, magnetic switch has a "perception", switch will act, usually call this
distance is "detection distance".
When install the magnetic switch on the cylinder, the first is put the magnetic switch installed
on the cylinder, the installation position of the magnetic switch adjusted according to therequirements of the control object , the adjustment method is simple, as long as after the
magnetic switch arrives the specified position, with a screwdriver tighten screw (or nut),
magnetic switch usually used to test the position of the cylinder piston, if detect other types
of workpiece position, such as a light color plastic workpiece would then choose other kinds
of sensors, such as photoelectric switch.

switches connected to the PLC. Optical fiber photoelectric switch is also a kind of optical
fiber sensors, optical fiber sensors sensing part does not have the circuit is connected, do not
produce heat, only using a few light, these characteristics make optical fiber sensor become
ideal choice in the dangerous environment . Optical fiber sensor can also be used for the key
production equipment's long-term high reliability and stability monitoring. Compared withthe traditional sensors, optical fiber sensors have the following advantages:
anti-electromagnetic interference, working in the bad environment, the transmission distance,
long service life, in addition, the head of the optical fiber has smaller volume, so can be
installed in the small place. Optical fiber amplifier according to the need to hold. For example,
electric spark fireworks in the production process may cause an explosion and fire, and light
will not become fire sources, not cause an explosion and fire, so the fiber optical detection
head set in dangerous places, will put amplifier unit set up in the dangerous places to use.
Optical fiber sensor is composed of optical testing head and fiber optic amplifiers , amplifiers
and optical testing head is the two parts of separation . Optical fiber sensor classified sensor
type and the light-transmission type . The sensor is based on optical fiber itself as sensitivecomponents, make optical fiber both have the role of feelings and passed tested information.
The light-transmission type is to be measured through the output terminal light signal
processing by the light signal input optical fiber which modulate by tested objects , the work
principle of light-transmission type optical fiber sensor is similar to photoelectric sensors'.
b. The application example of optical fiber photoelectric switch in the DL-MPS901A

1Electrical and mechanical installation
In the installation process, first fix the fiber optical detection head, put the fiber amplifiers
install in guide rail, and then two optical fiber that at the end of optical testing respectively
inserted into the two optical fiber hole of amplifier, when you wiring, please pay attention to
judge polarity and signal output power line according to the connection wire color.
Sensitivity adjustment
Optical fiber photoelectric switch is applied more and more in the production line application,
but in some application place where there is more dust, and easy access to organic solvent
and need higher performance, actually can choose some other sensors instead, such as
capacitive switch, electricity eddy proximity switch.

1.2.3 Photoelectric switch and application
a .Photoelectric switch introduction
Photoelectric switches usually use in some situations that environment condition is very good
and no dust pollution. The photoelectric switch almost has no effect on tested objects when itis working. Therefore, it is widely used in production line. Using the tiny beam, amplifier
built-in type diffuse photoelectric switches. Diffuse photoelectric proximity switch is working
which use the reflected light that use light to illuminate the tested objects , because the
reflected light is diffuse light , so it is called the diffuse photoelectric switch. It consists of
light (launch light) and photosensitive components (receive light) , light emitter and light
receiver are on the same side. When is is working, light emitter always emission testing light,
and if proximity switch within a certain distance ahead did not appear object, there is no light
is reflected to the receiver, photoelectric switches are in normal state and not move; And if
proximity switch within a certain distance ahead appear objects, as long as the reflected light
enough strength, the receiver receive enough diffuse light and will make proximity switch actand change the output state .
Besides has diffuse type photoelectric switches in the production line, also have cast type
(DuiShe type) and regression model (mirror reflection), all composed of emitting light source
and photosensitive components that accept the light, if Cast light is covered or reflected
because of the difference of detection object , the amount of light that arrive receiver part will
change. The receiver part will detect this change, and convert to electrical signals, running
output. According to properties, installation of tested object in the production line.
b. The application example of photoelectric switch in the DL-MPS901A flexible
manufacturing system
In this production line, return type optoelectronic switch uses the test that workpieces are put
full in the classification station slippery slot.
1 Electrical and mechanical installation
The photoelectric switch has power source polarity and output reverse connect protection
function. Photoelectric switch has self diagnosis function, when the environment change
(temperature, voltage, dust) redundant that was set meet the requirements, the stable indicatorlight display (if redundant is enough, the light bright,). When the receiver's photosensitive
components receive effective light signal, the transistor that control output will conduct,

Electricity eddy proximity switch to belong to one of the inductance sensor, is position sensorwhich has switch quantity output and use the eddy current effect to make. it consists of LC
high frequency oscillators and amplification processing circuit, when using metal objects to
close to this oscillation induction head that can produce electromagnetic field, make the
object internal generate electricity eddy current. The eddy current react on proximity switch,
make proximity switch oscillation capacity attenuate, internal circuit parameters change, thus
identify whether has metal objects close to it, and then control switch's lead or broken. The
project that can test by this proximity switch must be metal objects. No matter what kinds of
proximity sensors, when using must be pay attention to tested object's materials, shape, size,
and movement speed, and other factors.
During the sensor install and choose to use, have to seriously consider detection distance,setting distance, ensure the sensor reliable action of the production line.

programmable controller's abbreviations. It is a electronic system device of digital computing
operations that a microprocessor as core, specially designed for the industrial field application,
it uses programmable memory, in its internal storage to perform the logic operation, sequence
control, regular/count and arithmetic operation instructions, and through the digital or analog
input, output interface, control the various types of machinery or the production process. PLCis product that microcomputer technique combine with traditional relay contact control
techniques, it overcomes the complex wiring, lower reliability, high power consumption , the
poor universality and flexibility in the mechanical contacts relay contact control system,
make full use of the advantages of the microprocessor, and take care the skills and habits of
site electrical operation maintenance personnel, especially PLC programming, don't need a
special computer programming language knowledge, but using a set of simple instruction
form based on relay ladder diagram, make the user programming visual, intuitive and easy to
learn; The commissioning and check wrong is also very convenient. After users bought PLC
that what they need, just according to the hint of introduction book, do a small amount of
wiring and simple user programming work, you can be flexible and convenient appliedPLC to the production practice.
1. PLC structure and function of various parts
There are various types of PLC, function and command system are also different, but the
structure and the working principle is the same, usually is composed of main machine,
input/output interface, power supply expand device interface and external devices interface
and so on. PLC hardware system structure as below:
1) Main machine
The main machine includes the central processing unit (CPU), system program memory and
the user program and data storage. The CPU is the core of PLC, it used to run the user
program, monitoring input/output interface state, make logical judgment and data processing,
that means read input variables, completing various operating that the user instructions rules,
and send the results to the output terminal, and respond to external device (such as computer,
printer, etc) request and do various internal judgment, etc. PLC internal memory has two
kinds, one kind is system program memory, it main storage system management, monitoring
program and the program that do compile processing to user's program, the system program
has been fixed by manufacturer, users can not change; Another kind is the user program and
data storage, main storage application program that the user compile and all kinds oftemporary data and intermediate results.
2) Input/output (I/O) interface
-

DL-MPS901A flexible manufacturing system
http://dolang.cn TEL86-531-8758 6166 FAX86-531-8756 0072 13
The I/O interface PLC and input/output devices connected components. Input interface accept
input device (such as buttons, sensors, contacts and stroke switch, etc) control signals. Output
interface is main machine modification, debugging program and PLC monitor work state.
Through the special cable wire connect to PLC and computer, and use special software to do
computer programming and monitoring.3) Input/output expansion unit
The I/O expansion interface use for connect expand unit of expand external input/output
terminal to the basic unit (namely main machine) together.
4) External device interface
The interface can connect printer, bar code scanner, inverter and other external equipment to
main machine, and to complete the corresponding operation.
The experiment device providing main machine model are Siemens S7-300
312-1AE13-OAB0. Input points is 8, output points is eight.
2. PLC working principle
PLC is using the "order scanning, continuous cycle" way to work. That is when the PLCoperating, CPU according to the program storage in user memory that the user according to
control requirements compiled, according to command step serial number (or address date)
do periodic cycle scanning, if no jump instruction, then from the first instruction began
executing user program according to the sequence, until the program end. And then returned
to the first instruction start the next round of the new scanning. During every scanning
process, also must finish sampling to the input signal and refresh work to output state, etc.
PLC scan cycle must have input sampling, program execution and output refresh three stages.
PLC in the input sampling stages: first read into input terminal hige state or enter data that
storage temporary in the input latches by scanning mode according to the order, and writethem in the corresponding input status register, which is refresh input. Then close input ports,
into the program execution stage.
PLC in program execution stage: according to user program instructions stored order
scanning executes every instruction, after the corresponding operation and treatment, the
results were wrote output state register, all the content in the output state registers changes
along with the program execution.
Output refresh stage: when all the instruction execution, the hige state of output state register
in the output refresh stage sent to output latches, and through a certain way (broken
appliances, transistors or thyristor) output, drive the corresponding output devices work.
PLC programmingProgramming components
PLC is used in the software programming to achieve control requirements. When
programming uses all kinds of programming components, they can provide countless move
closes and move off contacts. Programming components is refers to the input registers, output
registers, bit memory, timer, clock, general-purpose registers, data register and special
function memory, etc.
The role of these memories PLC internal is similar to role of relay that using in the relay
contact control system, also have "coil" and "triggers", but they are not "hard" relay, is
storage units of PLC memory. When the logic state is "1" in the unit, means the
corresponding relay coil get electricity, its move close contacts closed, move break contacts
disconnect. So, these internal relay are called "soft" relay.

2) Programming language
The programming is that users according to the control object requirements, use
programming language provided by PLC manufacturers, describe the process of a control .
Ladder diagram language and instructions statement table language is the most commonly
used PLC programming language, and both of them always used joint .a. Ladder diagram language
Ladder diagram is a graphic language that demonstrates from relay contact control circuit
diagram. It is lent the move close, broken contacts, move coil and series and parallel terms
and symbols that similar to a relay, according to the control requirements, connect and into
graphics that show a logical relationship between PLC input and output , straightforward and
easy to understand.
In the ladder diagram always use graphic symbols to show PLC
programming components' move close and dynamic broken contact; Use ( ) show their
coil. Ladder-diagram programming's types use graphic symbols and labeled letters or severalto distinguish. Contacts and coils consisted independent circuit called network, use
programming software generated ladder diagram and statement to show there are network
numbers in the table program, allow taking network as unit to comment ladder diagram.
Ladder diagram design should pay attention to the following three points:
The ladder diagram according to from left to right and top to bottom to order. Each logical
lines (or says cascade) started in left bus, and then the contact's series, and parallel connection,
and the last is the coil.
Each step of the ladder diagram flows is not the physical current , but "concept current",
from left to right, its both ends not have power . The "concept current" is used to describevisually the coil through conditions that should meet in the user program execution.
Input registers uses to receive external input signal, but not drive by PLC other internal
relay touch points. Therefore, ladder diagram only appears input register contacts, and don't
appear the coil. Output registers are output program execution results to the external output
devices, and when the ladder diagram output registers coil to electricity, then there is signal
output, but not direct drive output devices, and through the relay, transistors or thyristor of
output interface to realize. Output register contacts also can be used by internal programming
b. Command statements table
Command statements table is a language that uses mnemonic runes to compile PLC program,
it is similar to the computer assembly language, but easy to learn and to understand thanassembly language, some instruction program is composed of instruction statement tables. An
instruction is composed of step sequence, instruction language and function device numbers
three parts.
2.2 Basic directive introduction

"1" means the action or electricity, "0" means no action or not powered.
Bit logical instructions scanning signals state 1 and 0, and according to the Boolean logic
combine. In these combinations born results 1 or 0, called "logic operation results (RLO)".
Boolean logic applied in the following basic instructions:
A "and" AN "and not"
O "or"
ON "or not"
X "exclusive or"
XN "exclusive or not"
O "before and after or"
You can use the following instruction nested expression:
A (" and "operation nested began
AN (" and not "operation nested began
O (" or "operation nested began ON (" or not "operation nested began
X (" exclusive or "operation nested began
XN (" exclusive or not "operation nested began
You can use the following instructions to end a Boolean logic string:
= assignment
R reset
S setting
You can use the following one of instructions, change the logic operation results (RLO) :
NOT RLO not SET RLO setting (= 1)

3.2 The Characteristics of Pneumatic Device
A pneumatic device is composed of the actuators that generate straight lines and rotation
action through compressed air, the valve of control actuator action, and the energy
components that provide the energy for pneumatic device.
Pneumatic, hydraulic and electrical are used in the operation medium of the industrial site.
Through the analysis of advantage condition and disadvantage condition of effective
operation medium, decided to an effective operating medium.

3.3 pneumatic actuator
Pneumatic actuator produces straight lines and rotation through the compressed air. The
pneumatic actuator is composed of cylinder that produces line action, the device that
produces the rotation. Cylinders including the single-acting cylinder, it use compressed air
produce one way action, the double-acting cylinder, it use compressed air to produce two way
action. Rotating device include concussion device, it limits rotation angle, pneumatic motor
with limited rotation angle.
3.3.1The single-acting cylinder
Piston the single-acting cylinder
The single-acting cylinder through the use of compressed air produce one way action, and
using a built-in spring and external force to produce other direction action. In the return
process, built-in spring is not strong enough for load, can only finish the cylinder back. In
return action, because spring force only equivalent to compressed air pressure 0.3-0.5
KGF/cm2, so if loading act on cylinder, cylinder cannot back.
Figure 3.1 Control principle of single-acting cylinder
The biggest stroke of the single-acting cylinder with built-in spring is within 100 mm. Due to
the bigger the volume of the cylinder, the longer the compressed air emissions time and spring
return response time, the biggest diameter was also limited to maximum 50 mm.
The single-acting cylinder need simple lines between the valve and cylinder, and consumes
half compressed air of double-acting cylinder.
The single-acting cylinder is mainly used for clamping, injection, extrusion and up and down,
do not need powerful force to return.

3.3.2 Double-acting cylinder
Double-acting cylinder use compressed air cylinder produce back and forward actions. Not
different with the single-acting cylinder, the use of double-acting cylinder no specific
condition, therefore, double-acting cylinder has been widely used.
Although double-acting cylinder is no limit on their stroke, considering the piston rod bending,
their stroke in general set within 2000 mm. Inner size scope of double- acting cylinder
between 4 mm-320 mm.

There is no piston rod in the rodless cylinders, outside of the air tube, cylinder move with the
piston. Rodless cylinders have two different types: one is use permanent magnet, another use
tube aperture (forming wedge between the sheet) to move follower. In magnetic rodless
cylinders, strong magnetic force of follower may make internal and external magnet fault
movement, and air may be leakage in the gap in the tube aperture rodless cylinders,.Figure 3.4 is rodless cylinder, its magnetic make follower move with piston. Form strong

3.3.3 Pneumatic rotating device
Swing device
Swing device has limited rotation angle, between the two places has intermittent movement
swinging. Swing device has two kinds of type: rack and pinion, blade
1. Rack and pinion rotating cylinder
A rack and pinion rotating cylinder use rack and pinion device mechanically convert linear
action of a double-acting cylinder to rotating action. The piston rod nc-copy theory driving
gear converts linear action of the piston rod to gear rotation action.
Although in some commercial rack and pinion rotating cylinder, the rotation angle can be up
to 720 degrees, but in the market, rotation angle mainly is 180 degrees. The stroke of piston
rod adjusts rotation angle through a rotating button.
Rack gear rotating cylinder quite expensive, need more installation space, but it has more
softening movement and the longer service life relative to the cylinder blade rotation

2. Blade cylinder
Blade cylinder uses compressed air direct rotating blades. Compressed air accessories that
installed in the cylinder limit the rotation angle. Rotating angle can be effectively to 300
degrees, but mainly in the market is 180 degrees.
Because of simple structure, low cost cylinder, little installation space, but because its brittle
structure, only small size cylinder within 50 mm diameter is effective.

4.4 Pneumatic control valves
Pneumatic control system is composed of signal components, control components and
actuators. As a signal and control component, valve influence the operation sequence and
state of actuators.
Actuator itself can't work. In the bus, drive control a stem behind the wheel to open or close
automatic door. The action of cylinder and valve is consistent, the state of valve through the
pole to operate, to close and open the door. Valve only use for signals, including the
operation of stem, control direction, speed, and the force of actuator.

piston, ball valve and plug valve is common form of valve, and in the international mainly
used in industrial settings. According to the function, valve can be classified into four groups:
Direction control valve or pass valve
Flow control valve
one-way valve
Pressure control valve
3.4.1 Structure and operation principle of direction control valve
Direction control valves can be divided to lifting direction valve and slide valve on the
structure. Based on how to seal, lifting direction valve is divided into ball seat valve and
board seat valve.
Lifting direction valve use a ball center, board or vertebral closed or open port. Through a
flexible seat to seal, can increase service life, to block the foreign material or dust enter, and
to promote the operation reliability. On the other hand, because of the complex structure, to
create enough strong operating force against reset spring force and compressed air force, so
the price is very high.
Slide valve use slide of spools open or close port. Not like lifting direction valve need to
resist reaction of compressed air, slide valve structure is simple, small. Because it move
successively in valve body, the valve can't be sealed up, reduce the service life, and easy to
receive damage of foreign material or dust.
Ball seat valve
Because of its simple structure and small size, the price of ball seat valve is low. The built-in
spring will push ball to seat place, to cut off the air flow that from supply line P to operation
line A. Press the piston to separate ball and seat, in order to make the compressed air from P
terminal into the operation terminal A. The pressure on the piston need strong enough to
block spring reaction and force that compressed air promote to the ball. When the piston rod
is released, the spring pushes the ball and makes the valve back to the initial position. The
ball seat structure can only applied in small size valve, and the normal size is 1/8 inches.
Disc seat valve

Disc seat valve is tight, and have high reliable operation. Because of cross parts of the air,
even in short distances can get it fully, the reaction time is short. The lifting valve has the
self-cleaning function; it can clear dust in the compressed air. It is not affected by the outside
subjects and greatly increases the reliability of operation, and increase the service life. On the
other hand, complex structure makes its price increased, and need more driving force.
Slide valve
Compare with lifting valve, slide is cheap than the lifting valve, and structure is simple, only
need small operation force. Because a line axis slide in the valve body, seal of valve is not
strict, thus, decrease the service life, and easily damaged by the foreign material.
If supply end P and vent R exchange function mutual, and a NC type slide valve can be used
as NO type slide valve. If R as the compressed air supply end , P as vent hole, the valve can
be used as a NO type valve.
Lifting valve can't convert from NC type valve into NO type valve.

3.4.2 Direction control valve application
Direction control valve is a basic valve, it control beginning, stop and direction of airflow
through control cylinder.
Direction control of a single acting cylinder
Figure 4.2 show the circuit diagram of back and forward action that control a single-acting
cylinder. Using 3/2 way valve control a single acting cylinder. After press the button on the
3/2 way valve (1.2) and electromagnetic valve P communicate with A, single-acting cylinder
move forward. When loosen button, the built-in spring reset to the normal position of valve,

and air of single-acting cylinder was vent out through the vent R, make cylinder move
backward.
If 1.0 cylinder is small or the distance between cylinder and control valve is short, cylinder
can directly be control by hand valve, as shown in figure 4.2 shows. The bigger cylinder
requires controlled by a bigger 1.2 valve.
Big flow manual valve can be difficult to find and search. If the distance between the cylinder
and the valve is far, after operation cylinder move backward, and when the valve has been
returned to normal position, the 1.0 cylinder need to spend a long time to drop the compressed
air. So the cylinder backward action needs longer response time. If that's the case, we will
introduce a institutions that direct control, as shown in figure 3.12.
Figure 4.2 single-acting cylinder control
Indirect control of single-acting cylinder
Figure 4.3 shows other circuit diagrams that control the single-acting cylinder. And the
difference with indirect control circuit that figure 4.2 describes is indirect control circuit use
1.2 manual control valves make 1.4 valve control the cylinder.
Because 1.0 cylinder is generally located on the machine's operation, the distance between
1.0 cylinder and 1.2 valve is very long. If the distance is long between 1.0 cylinder and 1.2
manual operation valve, the direct control structure is disadvantage to longer cycle time,
because gas consumption increase, return reaction time of air cylinder increase.
On the other hand, the indirect control structure that described in figure 3.12 is 1.4 valve near
cylinder installed, avoid the problems within direct control structure.

Figure 4.3 Indirection control of single-acting cylinder
Direction control of double-acting cylinder
Use 4/2 way valve or 5/2 way valve, has two operating lines, to control double-acting cylinder.
Press the button on the valve, connect P and A, and B and R make double-acting cylinder
forward. When loosen button, build-in spring make valve reset to the initial position, connect
P and B, A and R make cylinder back
4/2 way valve and 5/2 way valve have the same function and results. The two operations lines
A and B on the 4/2 way valve are vent hole R to blow off the gas, and A in the 5/2 way valve
deflated through R, B put gas through S. Most 5/2 way valve are sliding type, and most 4/2
way valve are lifting type.
Because of its simple structure, low price advantage, 5/2 way valve was widely used in the
industrial area.

Indirection control of double-acting cylinder
Figure 4.5 shows circuit diagram of indirect control double-acting cylinder. Similar to indirect
control of the single-acting cylinder, indirect control of the double-acting through the valve as
the main valve (or total valve), make the cylinder move as the need speed, and use small

valve (1.2 and 1.3) provide control signal.
Figure 4.5 Indirection control of double-acting cylinder
3.5 Flow Control Valve
Flow control valve control the flow speed. Hydraulic or pneumatic equipment control fluid
speed to adjust to the speed of actuator.
Pneumatic valve that Influent actuator speed including 2-way flow control valves, one-way
throttle valve and quick-discharge air valve. Although in science only 2-way flow control
valve is called the flow control valves, and one-way throttle valve and quick-discharge air
valve was classified as one-way valve, we will classify all the valves that impact speed as
flow control valves.
Two-way flow control valve
A 2-way flow control valve control the air quantity into the two directions
Noted that if the valve is installed between cylinder and direction control valve, the valve will
influent the speed of the cylinder back and forward.
Figure 5.4 shows structure of 2-way flow control valve.

One-way throttle valve will connect 2-way fluid valve and check valve together. Check valve
only make one way air flow, to control flow velocity of a direction. When the gas into the
direction of the test valve closed, the velocity is adjustable, and when gas into the check valve
opened direction, velocity can not be adjusted, because the across parts size of check valve is
greater than the control flow valves, and make the air flow through the check valve.
This valve is mainly used to control the speed of the pneumatic actuators, known as the speed
control valves. Figure 5.2 shows structure of a one-way throttle valve
Figure 5.2 one-way throttle valves
The valve has two control structures: inlet throttle control and its control will supply gas to
cylinder, Deflated throttling control, and its control gas deflated from the cylinder.
Inlet throttle speed control
Figure 5.3 show inlet throttle circuit diagram, Can adjust the air amount of supply cylinder
and to control the forward speed of cylinder.
Open 1.1 direction control valves, make 1.0 cylinder forward. Cylinder forward speed can be
adjusted through 1.02 speed control valves, speed control valves can control the air amount of
supply cylinder.
Back speed of cylinder is not adjustable, because the supply gas could not be controlled, when
the cylinder back, the gas on the piston rod on can free emission through the one-way valve.
In order to adjust the cylinder back speed, need to install another speed control valves to
control gas of supply piston rod.

If exert force in the same direction of cylinder action, inlet throttling control structure has no
effect. The structure is rarely used, because the change rates of load rise and fall in a wide
range.
Figure 5.3 inlet throttling speed control
Deflated throttling speed control
Figure 5.4 shows deflated throttling circuit diagram, it adjusts gas amount from cylinder
expulsion, to control the forward speed of cylinder. And the compressed air is a lot of
supplied to the piston end; the gas that total piston end expulsed can be adjusted through the
speed control valves, to control the cylinder forward speed.
When cylinder acting, maintain stress that role in the piston and on the piston rod, and
compared with the inlet throttling control structure, can obviously control speed. Deflate
throttling speed control structure mostly used in the pneumatic device. Need to install another
speed control valve in the piston to control the cylinder back speed.

Quick-discharge air valve is mainly used to increase speed of the cylinder. Figure 5.5 shows
the structure and operation principle of quick-discharge air valve. Supply the A end of
compressed air flow valve in the P end. When P end loses pressure, the gas in A end rapidly
be put off through deflate hole, and installed together with cylinder, the valve simplified and
shorten the put gas path, and thereby reducing the reaction. Rapid deflated increases the speed
of the cylinder.
Figure 5.5 rapid deflated valve
Pressure sequence valve
The operation principle of pressure sequence valve and the pressure reducing valve is the
same. If pressure of compressed air role in the Z end to the spring setting pressure, the valve
will send a output signal to A.
This valve is mainly used for particular pressure to convert control position that pneumatic
control pneumatic. Figure 5.6 shows the structure and operation principle of pressure
sequence valve.

Pressure sequence valves are 3/2 way that compressed air signal control through the spring
pressure simple external control. This valve is used in the limit switch environment, alternate
limit switches to test whether cylinder finishes back and forward movement.
Figure 5.7 is the application that use pressure sequence valve testing whether the order
finished the forward movement.
1.1 valve change direction by 1.2 valve, make the cylinder forward. Set the operation
pressure of the 1.3 pressure sequence valve higher than cylinder forward pressure, so that
when the 1.0cylinder finished forward movement, operate 1.3 valve.
The order of the cylinder pressure valve control position limit switch control as reliable, so it
is recommended for use in the special device inside.
The position of the pressure sequence valve control cylinder are not reliable than limit switch
control, so it is recommended for use in the special device.
Figure 5.7 use pressure sequence valve test position
3.6 Brief introduction of one-way control valves and two-way control valveThe difference between dual electronic control and single electric solenoid valves is that, for
single electric solenoid valves, when no electric control signal, valve heart in the role of
spring will be reset, and for double electric solenoid valves, there is no electric control signal
in both ends, the position of the valve heart is depend on the electric control signal before.
Note that the two electric control signal of dual electronic control cannot are "1" at the same
time, that is, in the control process not allowed two wire get the electricity at the same time,

otherwise, they can cause electromagnetic coils burned down, and of course, in this case the
position of the valve heart is uncertain
3.7 Exchange and install solenoid valves
If there is electromagnetic valve damage, need to replace a solenoid valve, can according to
the following steps install solenoid valves:
cut off air source, use screwdriver remove solenoid valves that have been damaged
Insert electric control joint to solenoid valves
Insert pneumatic tube into the fast connection of solenoid valve.
connect to air source, debugging with the hand control switch, inspect cylinder action
situation.
