9 Noise reduction measures Operating noise of pumps he normal operating noise of a pump and consequently the operating noise of the entire hydraulic system is largely determined by where and how the pump is mounted and how it is connected to the downstream hydraulic system. lso size, style and installation of the hydraulic tubing have a major influence on the overall noise emitted by a hydraulic system Noise reduction measures alking about operating noise of a hydraulic pump, primary and secondary pump noise has to be taken into consideration rimary pump noise is caused by vibrations of the pump body due to internal alternating forces stressing the body structure. Flexible elements help to prevent pump body vibration being transmitted to other construction elements, where possible amplification may occur. uch elements can be: Bell housing with elastic dampening flange with vulcanized labyrinth (1) Floating and flexible coupling (2) Damping rails (3) or silent blocks for mounting the electric motor or the foot mounting flange Flexible tube connections (compensators) or hoses on inlet, outlet and drain port of the pump. Exclusive use of gas tight tube fittings for inlet connections to avoid ingression of air causing cavitation and excessive noise. econdary pump noise is caused by vibration induced into all connected hydraulic components by the flow and pressure pulsation of the pump. his secondary noise adds typical 7-1 db to the noise of a pump measured in the sound chamber according to DIN (see diagrams on opposite side). herefore pipework, its mounting and the mounting of all hydraulic components like pressure filters and control elements has a major influence to the overall system noise level. ulsation reduction with precompression volume: he V is equipped with a new technology for flow ripple reduction. his method reduces the pulsation at the pump outlet by 4-6 %. hat leads to a significant reduction of the overall system noise without additional cost and without additional components (silencers etc.). he typical reduction reaches 2-4 db. hat means: with a pump of the V series the secondary noise adds only some 5-7 db to the pump noise instead of the usually found 7-1 db. Figure 2 compares the measured pulsation of a system with 6 pumps of 18 cm³/rev each. ast but not least the connection between pump and driving motor can be the cause of an unacceptably high noise emission. Even when the mounting space is limited there are suitable means and components to reduce the noise significantly. he vibration of the pump body, created by high alternating forces in the rotating group and the pulsation of the output flow excite every part of the system connected to the pump mechanically or hydraulically. 1) Bell housing 2) Coupling 3) Damping rails Figure 1: Components to avoid vibration transfer from the pump to the drive/installation and their position in the power unit (numbers refer to the text on the left) series 2 2 [bar] 18 V18R1K11NFW-series 2 16 V18R1K11NFW-series [s] 11.5 series 4 22 [bar] Figure 2: Comparison of the pressure pulsation in a system with 6 old V pumps versus the same system with 6 Vplus pumps. he pulsation reduction effect of the precompression volume is evident. Other measures mall diameter tubes do not only cause high flow speeds, turbulences inside the tubes and cavitation in the pump, they also produce noise. Only correctly sized connections of the largest possible diameter according to the port size of the pump should be used. 2 9 arker Hannifin GmbH

30 ressure compensators tandard pressure compensator code F* he standard pressure compensator adjusts the pump displacement according to the actual need of the system in order to keep the pressure constant. s long as the system pressure at outlet port is lower than the set pressure (set as spring preload of the compensator spring) the working port of the compensator valve is connected to the case drain and the piston area is unloaded. Bias spring and system pressure on the annulus area keep the pump at full displacement. When the system pressure reaches the set pressure the compensator valve spool connects port 1 to and builds up a pressure at the servo piston resulting in a downstroking of the pump. he displacement of the pump is controlled in order to match the flow requirement of the system. 1 M 1 tandard pressure compensator code F* * = pressure rating Q = included p Remote pressure compensator code FRC While at the standard pressure compensator the pressure is set directly at the compensator spring, the setting of the remote pressure compensator can be achieved by any suitable pilot pressure valve connected to pilot port. he pilot flow supply is internal through the valve spool. he pilot flow is l/min. he pilot valve can be installed remote from the pump in some distance. hat allows pressure setting e. g. from the control panel of the machine. he remote pressure compensator typically responds faster and more precisely than the standard pressure compensator and is able to solve instability problems that may occur with a standard pressure compensator in critical applications. he pressure pilot valve can also be electronically controlled (proportional pressure valve) or combined with a directional control valve for low pressure standby operation. 1 M 1 remote pressure compensator code FRC Q = included p Remote pressure compensator code FR1 Version FR1 of the remote pressure compensator provides on its top side an interface NG6, DIN 2434 (CEO 3 at R35H, NF D3). his interface allows a direct mounting of a pilot valve. Beside manual or electrohydraulic operated valves it is also possible to mount complete multiple pressure circuits directly on the compensator body. arker offers a variety of these compensator accessories ready to install. ee pages 38 and 39 of this catalogue. ll remote pressure compensators have a factory setting of 15 bar differential pressure. With this setting, the controlled pressure at the pump outlet is higher than the pressure controlled by the pilot valve.

31 oad-sensing compensators oad-sensing compensator code FFC he load-sensing compensator has an external pilot pressure supply. Factory setting for the differential pressure is 1 bar. he input signal to the compensator is the differential pressure at a main stream resistor. loadsensing compensator represents mainly a flow control for the pump output flow, because the compensator keeps the pressure drop at the main stream resistor constant. variable input speed or a varying load(-pressure) has consequently no influence on the output flow of the pump and the speed of the actuator. By adding a pilot orifice (Ø.8mm) and a pressure pilot valve pressure compensation can be added to the flow control function. ee the circuit diagram below, left. 1 M 1 oad-sensing compensator code FFC F Q = included n Ø.8 F F Q M 1 1 M 1 1 oad-sensing compensator code FFC external orifice and pressure pilot valve oad-sensing compensator with interface NG6 for accessories code FF1 = included p hown above is load sensing compensator code FF1 with an NG6 interface on top of the control valve. hat allows direct mounting of a pilot valve for pressure compensation. his version includes the pilot orifice. Due to the interaction of flow and pressure compensation this package has not the "ideal" control characteristic. he deviation is caused by the pilot valves characteristic. If a more accurate pressure compensation is required, the 2-valve load-sensing compensator code F1 can be used. he circuit diagram of this version is shown left. Here the interaction of the two control functions is avoided by using two separate control valves for flow and pressure compensation. he 2-valve compensator is equipped with an interface NG6 on the compensators top side.

32 Horse power compensators Hydraulic-mechanical horse power compensator he hydraulic-mechanical horse power compensator consists of a modified remote pressure compensator (Code **) or of a modified load-sensing compensator (Code *C*) and a pilot valve. his pilot valve is integrated into the pump and is adjusted by a cam sleeve. he cam sleeve has a contour that is designed and machined for the individual displacement and the nominal horse power setting. t a large displacement the opening pressure (given by the cam sleeve diameter) is lower than at small displacements. his makes the pump compensate along a constant horse power (torque) curve (see diagrams on opposite page). For all nominal powers of standard electrical motors arker offers a dedicated cam sleeve. he exchange of this cam sleeve (e. g.: to change horse power setting) can easily be done without disassembly of the pump. On top of that an adjustment of the horse power setting can be done within certain limits by adjusting the preload of the pilot control cartridge spring. hat allows an adjustment of a constant horse power setting for other than the nominal speeds (15 min -1 ) or for other horse powers. Ordering code for the horse power option he first digit designates the horse power setting: Code B = 3. kw etc. up to Code 3 = 132. kw he second digit designates the pilot flow source: Code internal pilot pressure, remote pressure function. Code C external pilot pressure, combines horse power compensation with load-sensing compensation. he third digit designates the possibility to adjust the overriding pressure compensation: Code comes with a top side NG6/D3 interface on the control valve to mount any suitable pilot valve or arker pump accessories. Code B has a threaded pilot port p (G1/4) to connect a remote pilot valve with piping. Code C includes a pilot valve for manual pressure adjustment. Max. setting: 35 bar. age 33 shows typical control characteristics and the available horse power settings for the different pump sizes and displacements.

34 Electrohydraulic p/q control roportional displacement control, code FV he proportional displacement control allows the adjustment of the pumps output flow with an electrical input signal. he actual displacement of the pump is monitored by an VD and compared with the commanded displacement in an electronic control module Q*-F (see opposite side). he command is given as an electrical input signal ( - 1V or resp. 4-2m) from the supervising machine control. he command can also be provided by a potentiometer. he electronic control module offers a stabilized 1V source to supply the potentiometer. he electronic control compares permanently input command and actual displacement and powers the proportional solenoid of the control valve. deviation from the commanded displacement leads to a modulation of the input current to the solenoid. he control valve then changes the control pressure (port ) until the correct displacement is adjusted. Version FV of the proportional control does not provide a pressure compensation. he hydraulic circuit must be protected by a pressure relief valve. U UQ M U s 1 1 roportionaldisplacement control code FV Q U Q = included p roportional displacement control with overriding pressure control, codes FR, FZ and FG In version FR an additional pressure compensator valve can override the electrohydraulic displacement control. hat adds pressure compensation to this control. he compensator valve has an NG6/D3 interface on top to mount a pressure pilot valve. When using a proportional pressure pilot valve an electro-hydraulic p/q control can be realized. he electronic driver modules are tuned for the valve type DE177KF to give best performance. he electronic control module Q*-.. (see opposite page) contains, beside the displacement control unit, also the driver electronics for the a. m. proportional pressure valves. Using ordering code FZ and specifying the desired pilot valve/compensator accessory, a complete multiple pressure adjustment can be mounted in our factory (see compensator accessories, pages 38 and 39) and the complete unit will be tested and shipped together with the pump. With ordering code FG the proportional pressure pilot valve and a pressure transducer (arker C 8181 CE) are included with the pump control. In combination with control module Q*-Q.. a closed loop pressure control of the pump outlet pressure is available. Module Q*-.. offers an electronic horse power limiter in addition to the closed loop pressure control. arker variable displacement pumps have a large servo piston. hat leads to a extremely robust and stable pump control. On the other hand that requires high control flows (up to > 1 l/min). arker has therefore chosen the 2-valve-p/Q control concept, because in this case a hydraulic-mechanical compensator valve takes care of the pressure compensation of the pump. hat allows a very fast pressure compensation and makes this the control unsensitive to fluid contamination. We see the 2-valve-concept as a contribution to system and pressure control safety.

36 Electrohydraulic p/q control roportional displacement control with shuttle valve subplate, code W* Because of the servo spring the proportional displacement control needs a minimum pump outlet pressure of bar to adjust the pumps output flow according to an electrical input signal. If the system does not provide enough back pressure - especially at low displacement and low load - there are two options: the shuttle valve subplate and the preload valve option. If an external auxiliary pressure is available, the control option W* is equipped with a shuttle valve circuit according to the diagram left. t a low pump outlet pressure the pump displacement adjustment circuit is supplied by the auxiliary pressure and allows adjustment of the pump to zero flow at zero pressure. If the pump outlet pressure exceeds the auxiliary pressure, the shuttle valve shifts to internal pressure supply. Depending of the pump size and the response requirements an auxiliary power source of 2-3 bar and 2-4 l/min is recommended. Note: pressure control is only available above the auxiliary pressure level and operation of the pump at zero flow and zero pressure requires extreme care to maintain lubrication of the rotating group.

37 Electrohydraulic p/q control Quick pressure relief manifold for proportional pump control, code VE* When working with a proportional pressure control on variable displacement pumps, pressure decrease can be slow. When the pump strokes to deadhead, there is no active pressure relief. o achieve a response similar to a valve controlled system, the quick unload manifold can be mounted to the pump outlet. his manifold includes a cartridge valve with a 4 bar spring preload. he pilot pressure supply for the compensator valve is passing this cartridge valve and creates a pressure drop across the poppet. t normal working conditions this pressure drop does not exceed 3 bar and the poppet stays closed. In a dynamic response situation the pressure drop can exceed 4 bar and the cartridge actively reuces the system pressure acoording to the setting of the proportional pilot valve. s the pilot pressure supply is fed through this manifold the compensator spool needs to be without internal orifice. Ordering code for the proportional displacement and pressure control for combination with the quick unload manifold is F for pressure compensation and F for closed loop pressure control (pressure transducer and proportional pressure pilot valve included). reload and quick unload manifold, code VVE* he combination of the preload and the quick unload function into one manifold can be ordered under the code VVE*. his manifold is also designed for direct pump outlet mounting. o maintain a secure function under all conditions the pressure compensator requires an external sensing line connected to the system side of the preload valve (see diagram left). he ordering code for this proportional displacement control option is F for pressure compensation and FE for closed loop pressure control. he ordering code for the function manifolds is shown below.

41 General installation information Fluid recommendations remium quality hydraulic mineral oil fluids are recommended, like H- oils to DIN 51524, part 2. he viscosity range should be 25 to 5 mm 2 /s (ct) at 5 C. Normal operating viscosity range between 12 and 1 mm 2 /s (ct). Maximum start-up viscositiy is 32 mm 2 /s (ct). Operating temperature -1 to + 7 C. For other fluids such as phosphoric acid esters or for other operating conditions consult your arker representative for assistance. eals NBR (nitrile) seals are used for operation with hydraulic fluids based on mineral oil. For synthetic fluids, as perhaps phosphoric acid esters, Fluorocarbon seals are required. Consult your arker representative for assistance. Filtration For maximum pump and system component functionability and life, the system should be protected from contamination by effective filtration. Fluid cleanliness should be in accordance with IO classification IO 446. he quality of filter elements should be in accordance with IO standards. Minimum requirement for filtration rate x (mm): General hydraulic systems for satisfactory operation: Class 2/18/15, to IO 446 x = 25 mm (ß 25 75) to IO 4572 Hydraulic systems with maximised component life and functionability: Class 18/16/13, to IO 446 x = 1 mm (ß 1 75) to IO 4572 It is recommended to use return line or pressure filters. arker Filter Division offers a wide range of these filters for all common applications and mounting styles. he use of suction filters should be avoided, especially with fast response pumps. Bypass filtration is a good choice for best filter efficiency. Installation and mounting Horizontal mounting: Outlet port side or top. Inlet port side or bottom, drain port always uppermost. Vertical mounting: haft pointing upwards. Install pump and suction line in such a way that the maximum inlet vacuum never exceeds.8 bar absolute. he inlet line should be as short and as straight as possible. short suction line cut to 45 is recommended when the pump is mounted inside the reservoir, to improve the inlet conditions. ll connections to be leak-free, as air in the suction line will cause cavitation, noise, and damage to the pump. Drain port Compensation may cause short-term (2 to 3 ms) flow increase, e.g. 3 l/min (V 16 to 23), 4 l/min (V 32 to 46), 6 l/min (V 63 to 92),8 l/min (V 14 to 18) and/or 12 l/min (V27). lease consider for dimensioning. Drain line he drain line must lead directly to the reservoir without restriction. he drain line must not be connected to any other return line. he end of the drain line must be below the lowest fluid level in the reservoir and as far away as possible from the pump inlet line. his ensures that the pump does not empty itself when not in operation and that hot aireated oil will not be recirculated. For the same reason, when the pump is mounted inside the reservoir, the drain line should be arranged in such a way that a siphon is created. his ensures that the pump is always filled with fluid. he drain pressure must not exceed 2 bar. Drain line length should not exceed 2 metres. Minimum diameter should be selected according to the port size and a straight low pressure fitting with maximised bore should be used. haft rotation and alignment ump and motor shafts must be aligned within.25mm.i.r. maximum. floating coupling must be used. Bellhousings and couplings can be ordered at manufacturers listed in this catalogue. lease follow the coupling manufacturer's installation instructions. Consult your arker representative for assistance on radial load type drives. tart up rior to start up, the pump case must be filled with hydraulic fluid (use case drain port). Initial start up should be at zero pressure with an open circuit to enable the pump to prime. ressure should only be increased once the pump has been fully primed. ttention: Check motor rotation direction.
