Accumulators - One way flow regulators "vsa" type

FOX - ONE WAY FLOW REGULATORS "VSA" TYPE

Technical Features:Plated carbon steel body.

USE: In most cases it is advisable to use a flow regulator on the fluid port for best regulation of accumulated fluid. The VSA series of flow regulators have been designed to give the most efficient and economic answer to this requirement. The flow set point is controlled by means of a set screw without the need of an external control knob. It can be used in any position. Values given on below table refer to the flow regulator alone. When used with the accumulator, it is certainly much higher, depending on nitrogen precharge pressure.

Accumulators - Filling and testing

FOX - FILLING AND TESTING UNIT TYPE "AR"

The precharge valve is an essential device for filling and checking nitrogen content into the accumulators. Made of tropicalized carbon steel this valve can be used for a maximum working pressure of 350 Bar. It is supplied in a special case which enclose a pressure gauge and 2,5 meters of hose for connection to nitrogen bottle.

AR 4 0 > 160 BAR

AR 6 0 > 400 BAR

INSTRUCTION FOR USEHow To Check Nitrogen Pressure:

a) If the accumulator is connected to the systems please check there is no pressure on the oil side. Turn anticlockwise the valve knob until it is fully disingaged and install it on the accumulator.b) Close the nitrogen discharge valve and turn the "AR "valve knob clockwise until the pressure gauge signals there is not internal pressure left or knob is fully turned clockwise in the event accumulator is fully discharged.c) Once nitrogen pressure is checked, gently unscrew discharge valve until pressure start decreasing. Once wanted nitrogen pressure is reached fully unscrew valve knob, open the nitrogen discharge valve to eliminate residual pressure and unscew "AR" valve from the accumulator re-install protection cap of filling valve on accumulator turn strongly.Filling Of Nitrogen: Repeat A.M. operations connecting the nitrogen bottle quick realease coupling before opening the valve knob. Start filling nitrogen very gently. We recommend to use a gas pressure reducer installed on the bottle in order to avoid over-pressurizations of the accumulator body during filling operation, especially when the precharge is low in pressure. Check nitrogen precharge every approx six months.

How to Disassemble

1) Discharge nitrogen from the bladder by using our "AR" charging and gauging assembly.

2) Make sure that the nitrogen pressure is nil and then take apart all the components of the nitrogen valve.

3) Set the accumulator into a vice, remove the vent (bladder) screw, then unscrew the threaded sleeve which retains the fluid valve, then push the complete valve assembly inside the accumulator and remove the internal seal.

4) Remove, by folding, the rubber-metal seal inside the accumulator which allows the extraction of the fluid valve.

5) Unscrew the nut which retains the bladder, remove the identification plate and extract the bladder.


How to Assembly

6) After having replaced all defective parts andchecked that the accumulator body is internally clean repeat all previousoperation inversely. Pay attention there is no air inside the bladder by foldingit before reintroduction into the accumulator body.

7) For an easy introduction of the bladder inside the accumulator bodywe suggest the use of a rod having one end threaded M11x1 which canbe screwed on to the bladder threaded port. We strongly recommend tofill the accumulator with oil in a quantity of 5% of total volume capacity,this will allow the bladder to get the right position when filled with nitrogen.We also recommend to fill nitrogen very slowly specially when the bladder is initially expanding.

Accumulators - Description and Function

FOX - DESCRIPTION AND FUNCTION

The hydropneumatic accumulator is a device that utilizes the compressibility of gas in order to permit hydraulic circuits to store quantities of fluids under pressure which are considered non compressible.FOX manufactures bag or membrane type hydropneumatic accumulators. Both types of accumulators are constructed from a single body by deforming highly resistant steel tubes.Various alternatives are offered regarding elastic components compatible with the type of fluids and operating temperatures utilized, the same for fluid or nitrogen side valves, available in various methods of construction.

FunctionsA) Accumulator under nitrogen pressure without fluid pressure.B) Accumulator under minimum system pressure. This condition must be always verified to guarantee that the bag or membrane not undergo precocious wear and tear due to contact with the metal body during every work cycle.Therefore value of pressure least of the fluid has always to be the 10% superior to pressure of pre-loading nitrogen pressureC) Accumulator under maximum system pressure. In this case we have maximum accumulated fluid capacity due to the difference between the initial and final nitrogen volumes V1-V2= ?V (fluid volume). It is important to establish prior to achieving maximum fluid pressure that it is inferior to that of the maximum permissible pressure of the body. Furthermore, in order to avoid any excessive deformation of elastic parts it should be taken into consideration that limiting parameters exist between pre-loading pressure and maximum fluid pressure. It is therefore advisable that the value of this rapport be inferior to 4.

Construction DifferencesThe bag accumulator represents the ideal functional condition in particular concerning the operation of the more common anti-extrusion poppet valve. With this type of accumulator maximum results are achieved, therefore, very high discharge capacity, high yield, perfect gas-fluid separation and minimum reduction of osmosis effect since bag stretching is minimal. The membrane type accumulator of more simple construction is very economical and can be mounted in any position as well as on any type of mobile machine. It has a higher osmosis effect due to higher membrane deformation. The principal limiting factor is however in its low spontaneous capacity, therefore, its use is limited to applications where this is not requested (max. 50 It/min).FOX constructs membrane accumulators up to a capacity of 2,3 liters and the remainder of its production in bag type.

APPLICATION AND MEASUREMENT

Energy AccumulatorIt is improbable that an hydraulic system use all of its capacity on a continuous basis. An hydropneumatic accumulator can store a certain amount of fluid in the tank discharge phase and therefore help the pump when maximum capacity is requested.It is therefore possible to measure the same system with reduced pump capacity and consequently save installed capacity.Moreover, fluids tend to heat less, less system noise together with a flattening out of pressure and water hammer absorption variations due to rapid valve operation.The following formulas are the basis for measuring the exact FOX accumulator either for this application or for all other applications in which its use is requested. In all applications the following isothermic formula is used when charge and discharge times are prolonged at constant temperature (~3 minutes) and the adiabatic formula in the presence of frequent cycles.

Temperature InfluenceOn order to obtain maximum yield from the accumulator the nitrogen pressure must be: P0 = 0, 9 · P1


Y Rapporto delle temperature specifiche di Azoto=1,4

When a temperature change takes place in the system (T2) it is necessary to regulate the accumulator taking into consideration this variable. Consequently the values obtained from the previous formulas will be varied in the following manner:

Vot = Accumulator volume in consideration of temperature variation.Another factor influenced by temperature is the nitrogen pre-loading phase also subject to pressure variations in function of temperature change. Considering that pre-loading pressure is carried out at an environmental temperature of 20° C, the formula to apply is the following:

P0 at 20° C = Value of nitrogen pre-loading pressure at 20° C in consideration of pressure increase when temperature rises to value T2

Hydraulic Spring Balancing of Forces for Hydropneumatic Suspension

In these applications the accumulator volume is obviously a function of the fluid volume to be absorbed and the pressure variation within which a certain course is desired from one or more cylinders (formula a). It should also be considered indispensable to insert an unidirectional flow regulator inline to permit rapid accumulation and controlled return. As far as the closed circuits are concerned, it is also obligatory to insert a safety valve set at 5% less than the maximum accumulator pressure.

Leakage Compensator

A hydropneumatic accumulator can be utilized to maintain the pressure in a closed hydraulic circuit compensating the losses due to gasket blow-by and valve leakage. To regulate it is necessary to quantify the volume of fluid to be stored also in relation to the amount of time under pressure, in addition to establishing minimum and maximum system pressures and applying formula (a) for sizing.

The value of P0= 0.9 • P1


Thermal Expansion CompensatorIn a closed hydraulic circuit subject to temperature variations, a variation of pressure takes place due to fluid expansion.A FOX hydropneumatic accumulator is able to absorb the expanded quantity of fluid and limit pressure increases to within the values desired.To determine these values it is necessary to calculate the volume of fluid to be absorbed with the following formula:?V=V o (T2-T1) o ß where V = Volume of tank fluid (lt) and ß = coefficient of cubic expansion of fluid.Applying formula (a), the volume of the accumulator is selected in relation to the desidered pressure at maximum temperature. Consider as well the formulas that take into consideration the measurement of temperature influence (c,d)

Water Hammer/Shock AbsorbtionAs in the preceding example it is necessary to calculate the volume of fluid that generates water hammer and apply formula (a) for setting a value indicating P2 as maximum desired pressure.It is evident that the difficulty consists in quantifying the volume of fluid that generates water hammer subject to innumerable variables such as: tube diameter and length, pump capacity and pressure, valve closure time, temperature, type and viscosity of fluids etc...Our technical office, due to its vast acquired experience can help to resolve such application problems.

Pulsation DampenerIt is well known that pumps, in particular plunger pumps, have a more or less fixed capacity determined by their displacement and revolutions per minute.

190Vo = ------ o 4 = 2,8 lt. 270

For example, if a pulsation of 5% above average delivery pressure is desired (Pm) the values will be P2 = Pm + 5 and P1 = Pm - 5.The value P0 relative to the precharge pressure must be:P0 = 0.6 . P1 for simplex and duplex pumpsP0 = 0.7 . P1 for triplex pumpsP0 = 0.8 . P1 for quintuplex pumps and beyond.For the precharge phase consider formula (d) which takes into consideration eventual temperature variations during the work phase.

In practical use, an easier way to calculate this volume has been developed experimentally and has been proven to be very useful: Vo = C . Z where Z is the coefficient of the displacement of delivery of one revolution (c) of the pump (in liters), to obtain the volume of desired residual pulsation.

For this specific application it should be noted that in addition to different types of elastomers, various alternative body constructions can also be supplied which are not provided in this catalog, such as the following: dampeners with larger inlets with improved yield according to pressure or accumulators constructed without poppet valve, direct flow passages or anti-extrusion screen and versions with welded, stainless steel bodies for low pressure. Dampeners with inline flow passages, etc.

Fluid SeparatorAn hydropneumatic accumulator can be utilized to transfer pressure on two different fluids that must not come in contact with each other. For this application in addition to requesting elastomers compatible with the fluids utilized it is necessary that the nominal value of the accumulator be 25% greater than the maximum quantity of fluid to be transferred in order to avoid excessive stretching of the elastomeres.

Accumulators With Additional Gas CylindersWhen in an hydraulic circuit the difference between maximum and minimum pressure is minimal and requires a considerable accumulation of fluid it is possible to connect additional cylinders of nitrogen to the accumulators in order to receive the total requested volume (?V) reducing the number of installed accumulators and


exploiting even more the single capacity of accumulation. For regulation consider formula (a) bearing in mind that in addition to the formulas of temperature influence (c,d) we must also consider the quantity of gas divided in two parts: one in the accumulator and the other in the additional cylinder. In the first case, it is indispensible that at least 25% of nominal accumulator volume remain when maximum value pressure is reached (P2), therefore ?V = 0,75 • V0 where V0 is the accumulator volume not considering the volume of the additional cylinders. The pre-loading nitrogen pressure must be Po = P1 • 0,97.

Other ApplicationsProtection of pressure control and measuring instruments.Noise reduction of system.Timer for pressure rise.

GENERAL NOTES FOR ASSEMBLY AND MAINTENANCE

Before effecting assembly check and compare data stamped on body or data plate of FOX accumulator with respective system, in particular maximum permissible pressure and pre-loanding pressure. An incorrect pre-loading pressure selection often negatively influences accumulator life time.

InstallationWhen the possibility exists, in order to achieve maximum yield, it is preferable to mount the accumulator as close as possible to the operator. The ideal position for the bag accumulators is from the vertical (with the nitrogen valve towards the top) to the horizontal position. Membrane accumulators can be mounted in any position. It is advisable to leave accumulator data plate visible as well as 15 cm space around the nitrogen valve permitting easy access for controls and pre-loading regeneration.

Fastening in PositionFor small volumes installed on fixed machinery a standard screw thread attachment is sufficient, for larger volumes fixing brackets or collars are necessary which protect the accumulator against vibrations or eventual impacts. At any rate it is absolutely prohibited to carry out welding on the bodies of the accumulators.

Start UpBefore beginning the work cycle make sure that the circuit pressure limiting valve is connected directly to the accumulator. Bleed the air out of the fluid side utilizing the special screws provided on poppet valve type and furnish and fit a retaining valve at pump outlet that protects it from backflow. We also recommend a cutoff and drain valve that permits maintenance during the working phase of the system as well as a undirectional on line rate of flow regulator in order to regulate accumulator discharge flow.


Pre-Loading GasFOX hydropneumatic accumulators are usually already loaded direct from the factory with the quantity of gas stipulated during the order phase and indicated on the data plate or stamped on accumulator body. This operation takes place at room temperature (~20° C); different working temperatures require different pre -loanding procedures (see formula d).

Control of Gas Pre-LoadingIt is advisable to control pre-loading pressure within 10 days after system start up and succesively every 6 months. Controls can be carried out easily from the fluid side with the accumulator mounted on system. This test method is based on the fact that, during the slow drainage phase of an accumulator full of fluid, the pressure on the accumulator side initially diminishes slowly according to laws regarding the physical properties of gas, but then suddenly drops off when the relative pre-loading gas value is reached. Such a phenomenon can be noticed wìth the aid of a manometer measuring accumulator fluid pressure directly. It is however also possible to control gas pre-loading from the gas side with the aid of the pre -loading device (AR), which also permits regeneration or pressure increase through bottled dry nitrogen. It is absolutely prohibited to utilize compressed air, gas cylinders or other types of gas. It is indispensable that the control or pre-loanding pressure variation be carried out in the absence of pressure on the fluid side no matter whatever accumulator is mounted on the system. The space above the nitrogen valve in order to be able to reach the pre-loading equipment must be at least 15 cm.

Accumulator Flow CapacityIn selecting an accumulator, in addition to volume, maximum pressure, temperature and general utilization conditions we must also consider incoming and outgoing maximum consented flow capacity. The recommended values of maximum flow capacity under working conditions for each type of accumulator are reported in the technical tables. In system with the possibility of higher than permitted flow capacities there exists the possibility of bag or membrane prolapse, that is, the accumulated fluid is not restored due to anticipated closure of the elastic part on accumulator bottom through anti-extrusion screen or closure of poppet valve. This phenomenon normally occurs when the accumulator lacks outgoing flow regulation and does not take into consideration that this is due to gas expansion, therefore with the possibility of very high spontaneous flow notwithstanding reduced passage diameters. We therefore suggest the prevision of an on line unidirectional flow capacity regulator during the project phase that permits outgoing accumulator flow control. For this particular function, FOX has its own line of efficient, simple and economic regulators (series VSA).

General Testing and Quality Control


FOX hydropneumatic accumulators are all individually tested at a pressure =1.5 greater than maximum consented pressure stamped on accumulator body.For total quality concerning every consignment in addition to specific certification on the part of the client there is also an enclosed internal certificate certifying testing undertaken in dynamic working conditions carried out singularly on each individual piece.

Italian RegulationsHydropneumatic accumulators enter under the norms regarding pressurized instrumentation controlled by ISPESL which requires testing in their presence for volumes over 25 liters of capacity.

International Testing RegulationsHydropneumatic accumulators are subject to different norms according to which country they are utilized in . While awaiting European regulations to unify testing procedures and norms, the most we can do is list the most requested boards that govern the norms in the following table. Such testing must be requested during the cost estimate phase due to the fact that the price of the accumulators obviously subject to price increases, as everything else, determined by longer delivery time.

Quality controlFOX hydropneumatic accumulators are constructed following the precise guidelines regulating construction norms. All mechanical turning (C.n.c.), automated welding (ARGON unit), bags and membranes molding, assembly, painting and testing are carried out and controlled during the work process directly in our factory shop area 1500 m2. The parts which are forged externally are subject to careful inspection by a Giraud magnetic crack detector. Our constant efforts to improve quality have enabled us to realize and perfect the only welded monolithic (series H) membrane accumulator on the market. The principal innovation that differentiates this gamma from all the other competitor products is that it is constructed of a single body and is not welded at its largest diameter, a guarantee of safety at high pressures together with the fact that it avoids excessive membrane heating at points where membrane is located near fluid and nitrogen side gates.Both models with patent regularly deposited.

FOX - ACCUMULATORS: Tables

Simplified table for measuring the quantity of accumulated liquid, in relation to the particular type of accumulator utilized in the ADIABATIC condition.

EXAMPLE: In a system we know the value of the maximum pressure P2 and minimum pressure P1. Measure the nitrogen precharge pressure P0 with the formula P1 x 0.85 (fixed value) = P0.Measure the compression ratio P2 : P0 = mPIdentify the obtained value (mP) in the column.All reported values on the corresponding lines refer to the quantity of accumulated fluid in relation to the volume of accumulator utilized.The number of cycles is inversely proportional to the increase of the compression ratio. It is useless to compress a precharged accumulator from 30 bar of nitrogen up to 120 bar of oil, when in the system for example, the minimum pressure never goes below the value of 70 bar. In this case, other than reducing membrane life, the nominal performance of the accumulator is not improved. The same quantity of accumulated oil is obtained with a precharge pressure of 60 bar and the nominal nitrogen volume is reduced by half.

Pressure switches - K4 series

FOX - "K4" SERIES ADJUSTABLE MONO-CONTACT PRESSURE SWITCH

K4 adjustable pressure switches permit opening or closing an electric circuit in order to reach predetermined pressure value. The preset pressure is found by rotating the external screw located at the center of the instrument, by rotating the screw clockwise to encrease and viceversa to decrease the value. Mechanical stops protect both the spring and the micro-switch from over pressurization. The main characteristic of this series is that this miniature pressure switch can be totally dismanted.
