Introduction Series PAVC 33/38/65/1 General Description All control is achieved by the proper positioning of the swash plate. This is achieved by a servo piston acting on one end of the swash plate working against the combined effect of the off-setting forces of the pistons and centering spring on the other end. The control spool acts as a metering valve which varies the pressure behind the servo piston. As shown in Figure 1, the amount of flow produced by the Parker Piston Pump is dependent upon the length of stroke of the pumping pistons. This length of stroke, in turn, is determined by the position of the swash plate. Maximum flow is achieved at an angle of 17. The rotating piston barrel, driven by the prime mover, moves the pistons in a circular path and the piston slippers are supported hydrostatically against the face of the swash plate. When the swash plate is in a vertical position, perpendicular to the centerline of the piston barrel, there is no piston stroke and consequently no fluid displacement. When the swash plate is positioned at an angle, the pistons are forced in and out of the barrel and fluid displacement takes place. The greater the angle of the swash plate, the greater the piston stroke. The centerline of the pumping piston assembly is offset from the centerline of the swash plate. Therefore, as shown on the accompanying Figure 1A, the pistons effective summation force tends to destroke the swash plate to a vertical (neutral) position. This destroking force is balanced as the swash plate is angled by the force of the servo piston.

Control Options Series PAVC 33/38/65/1 Pressure Compensated Control Swash plate angle controls the output flow of the pump. Swash plate angle is controlled by the force generated against the swash plate by the pumping pistons and by the force of the servo piston. The force of the servo piston is greater than the force of the pumping pistons when both are at the same pressure. y means of internal porting, pressure is connected from the output port to the servo piston via orifice (E), and to the control spool via passage (D). Also pressure is applied to the control spool chamber thru orifice (F). As long as the pressures at both ends of the control spool remain equal, the spool will remain offset upward, due to the added force of the spring. When pressure reaches the setting of the compensator control, the dart leaves its seat causing the pressure in the spool chamber to be reduced. The spool now moves downward causing pressure in the servo piston cavity to vent via port A. The reduced pressure at the servo piston allows the servo piston to move to the right. This movement reduces the angle of the swash plate and thereby reduces the pumps output flow. As pump pressure on the control spool drops below pressure and spring force in the spool chamber, the control spool moves upward to maintain an equilibrium on both sides of the spool. If pump pressure falls below compensator control setting, the control spool moves up, bringing the pump to maximum displacement. P Adjustment of PAVC Pumps PROCEDURE: a. Standard Pressure Compensated Pump Pumps are shipped from factory with a differential pressure of approximately 15 (1 bar) on PAVC 33/38/65, PAVC 1 is 3 (21 bar) at 5% of maximum swash angle. Differential pressure will not normally change through the life of the pump. If this control has been tampered with, a close approximation of the correct setting can be made as follows: Dead head the pump (no flow) with a -27 bar (- 3 ) gauge in the OUTLET (not the low signal port), back the pressure compensator adjustment out (full counterclockwise). The gauge should read between 22-26 bar (325-375 ) PAVC 33, 38 & 65, 34-4 bar (5-575 ) PAVC 1. If the gauge reads different than this, turn the differential adjustment knob (Differential Option 4) or add/remove shims (Omit Option) until correct pressure figure is reached.

Control Options Series PAVC 33/38/65/1 Remote Pressure Control Control Type (M) Remote control of the PAVC output pressure can be achieved by controlling the pressure in the low signal port when the pump is set up for Control Type (M). A manual, hydraulically piloted, electrical or electroproportionally controlled pressure control device is installed in the line from the low signal port to tank. The pump will then maintain pressure approximately equal to the pressure in the port plus the pump differential setting. Low Pressure Standby This option can be used as an alternative to the load sensing option (A) to achieve low pressure standby. Minimum standby pressure is somewhat higher than that achieved using option (A). In the compensating mode there is approximately 1.1 LPM (.3 GPM) flow from the low signal port in addition to 3.4 LPM (.9 GPM) flow from the control drain port A. Multiple Pressure Standby If the pressure level in the low signal port is limited by a relief valve, as the desired pump outlet pressure is reached, the relief valve in the port will allow the pump to standby at a preset pressure. Adding to this concept, multiple, remotely piloted relief valves plumbed in parallel in the port line can yield multiple, sequential pressure settings. Electrohydraulic Pressure & Flow Control A proportional pressure control valve can be used in place of relief valves to give variable pressure control proportional to an electrical input signal to the valve. y combining this arrangement with a swash plate position sensing device, amplifier, and logic circuit, servo control of pressure and/or flow is achieved. NOTE: In most systems, a load equivalent to the minimum operating pressure of the pump cannot be guaranteed. ecause of this, a sequence valve is required in the discharge line to maintain servo flow control. Please refer to ordering information section for servo components.

Control Options Series PAVC 33/38/65/1 Pressure & Flow Control (Load Sensing) Control Type (A) Flow control is achieved by placing an orifice (fixed or adjustable) in the pump outlet port. The pressure drop ( P) across this flow control is the governing signal that controls the pump s output, as explained below. Whenever the pressure drop at the flow control increases (indicating an increase in output flow), the pump attempts to compensate by decreasing the output flow. It does this by sensing the lower pressure on the downstream side of the flow control via line (C), which is balanced against the pump pressure via passage (D), on the control spool. The control spool is forced down against the control spool spring by differential pressure. This vents the servo piston cavity, destroking the pump to a point where the set pressure drop across the orifice is maintained and the flow is obtained. The converse of this is also true whenever the pressure drop decreases (indicating a decrease in output flow). In this case, the control spool is forced up. This increases pump displacement in an attempt to maintain the predetermined pressure drop or constant flow. It should be noted that the pump is still pressure compensated and destrokes at the selected pressure setting. The pressure compensator control will override the flow control whenever the pressure compensator control setting is reached. Low Pressure Standby This arrangement can also be used to provide low pressure standby by venting the port through a simple on/off valve suitable for flows of 3.8-7.6 LPM (1-2 GPM). When flow or pressure is required, this valve is closed allowing system pressure to build behind the control spool and bringing the pump on-stroke. Load Sensing If, instead of measuring the pressure drop across the orifice in the pump outlet port, it is measured downstream of a directional control valve, a constant pressure drop will be maintained across the valve spool. This results in a constant flow for any given opening of the directional control valve regardless of the work load downstream or the operating speed of the pump. The pump senses the amount of pressure necessary to move the load and adjusts output flow to match the valve opening selected and pressure to overcome the load plus the preset P across the valve spool. The benefits of this arrangement are that excellent, repeatable flow characteristics are achieved, and considerable energy savings are realized while metering, compared to using a straight pressure compensated system.

Control Options Series PAVC 33/38/65/1 Pressure & Power (Torque) Control Control Type (H) The power control is sensitive to the position of the servo piston. When the servo piston is to the right, the swash plate causes low flow and the power control piston develops maximum spring pressure on its companion poppet (mechanical feedback). When the servo piston is left and the flow is high, the power control piston reduces spring pressure on the poppet. This allows it to open under less pressure in the control spool chamber, thereby venting some of the pressure in the control spool chamber. As with the operation of the pressure compensator control, this allows the control spool to move downward, venting the servo piston cavity and causing the servo piston to move to the right. This reduces output flow and thereby power. As indicated in the pictorial drawing, pressure in the control spool chamber is affected by both the pressure compensator control and the power control. The resultant pressure in this chamber is a function of the set points of these two controls. oth set points are adjustable.

NOTES: 1. Consult factory for information relative to pump option selection and additional components required for desired pump function. 2. For electrohydraulic flow and pressure control of one or two pumps, make electrical connections per Figure IV. When one pump is used, omit connections to pump #2 feedback. 3. For electrohydraulic flow only, eliminate pressure command signal and place jumper between Press CMD and +1V terminals (compensating pressure will be controlled by maximum setting on pump or remote compensator if used). 4. For electrohydraulic pressure only, eliminate volume command signal and place jumper between VOL CMD and +1V terminals or use 81179 pressure driver card. 5. Figures I thru III show nominal input vs. output relationships. The actual values will vary with component tolerances. Full volume range will be realized with to 7 volts. Full pressure range will be realized with to 7 volts, or -5MA. 6. Pump shown is a clockwise rotation. For a counterclockwise rotation LVDT feedback is on opposite side. 7.

Installation Information Series PAVC 33/38/65/1 Use Of A Relief Valve The use of a relief valve, while not mandatory is recommended in the main circuit to suppress hydraulic shock loads and additional system protection. If a minimum volume stop is used, the use of a relief valve is mandatory. Fluid Recommendations Premium quality hydraulic oil with a viscosity range between 15-25 SSU (3-5 cst.) at 38 C (1 F). Normal operating viscosity range between 8-1 SSU (17-18 cst.). Maximum start-up viscosity is 4 SSU (1 cst.). NOTE: Consult Parker when exceeding 71 C (16 F) operation. Oil should have maximum anti-wear properties, rust and oxidation treatment. Filtration For maximum pump and system component life, the system should be protected from contamination at a level not to exceed 125 particles greater than 1 microns per milliliter of fluid. (SAE Class 4/ISO 16/13). Due to the nature of variable displacement pumps, variations in pump inlet conditions, fluid acceleration losses, system aeration, and duty cycle we do not recommend suction line filters. We do recommend the use of a properly sized, in-tank suction strainer. Contact your Parker representative for assistance. Start-Up On initial start-up, the case should be filled with oil, pressure should be reduced and the circuit should be open or the air bled from the pump outlet to permit priming. Use of the airbleed is recommended on initial start-up. See Installation and Mounting Section to connect airbleed. Inlet Conditions Not to exceed.17 bar (5 In. Hg.). Vacuum at 18 RPM on petroleum base fluids. See recommended speed spectrum for specific inlet conditions. Shaft Rotation and Line Up Pump and motor shaft alignment must be within.1 TIR maximum, using a standard floating coupling. Please follow coupling manufacturer s recommended installation instructions to prevent end thrust on pump shaft. Turn pump to assure freedom of rotation. Pump and motor must be on a rigid base. Installation and Mounting When a PAVC Series Pump is mounted above the fluid level, the position of the control drain is not restricted but the inlet port should not be on the bottom (PAVC1). When a PAVC Series Pump is mounted below the fluid level the position of all ports are not restricted. The control drain should be a separate line to the reservoir and extend below the oil level as far from the inlet line as possible. The control drain line can be filtered and/or cooled (must not exceed 7 bar (1 ) back pressure). Suggested maximum line length is 1 feet. A built in airbleed is standard on all PAVC 33, 38, 65 and 1 Pumps. To connect, remove airbleed drain plug and connect a line unrestricted to reservoir extending below minimum oil level. ack pressure in this line must not exceed.28 bar (4 ). Special Installations Consult your Parker representative for any application requiring the following: Pressure above rated, drive speed above maximum, indirect drive, fluid other than petroleum oil, oil temperature above 71 C (16 F). Inlet Pressure Not to exceed 1.72 bar (25 ). The coupling should be sized to absorb the peak horsepower developed. 46
