 This control method achieves both low-pressure high-flow-rate control and high-pressure low-flowrate control with a single pump and this helps reduce power consumption and suppress oil temperature rise.  When the discharge pressure approaches t h e p r e s et p r e s sur e PL , t h e di s c h a r g e r ate automatically decreases to QL.  The discharge rate automatically changes according to increase/decrease of the actuator pressure and this enables switching of the feedrate.  The feedrate switches to a low value at the start of machining.

Operating principle of variable displacement piston pumps

Piston

Kidney

Shaft Suction port

Discharge port

Trunnion Swash plate

Cylinder block Kidney

 When the shaft is rotated by an electric motor or an engine, the cylinder block is rotated on the valve plate surface while maintaining a slight clearance, and the pistons contained in the cylinder block reciprocate following the swash plate. The volume of the oil chamber varies with the reciprocating movement of the pistons, sucking in and discharging oil.  During the suction process, an amount of oil corresponding to the piston stroke is drawn through the suction port of the endcap, passing through the valve plate port of the cylinder block, while the piston moves from the bottom dead point to the top dead point. During the discharge process, oil is forced out through the discharge port of the end-cap, passing through the valve plate port, while the piston moves from the top dead point to the bottom dead point.  One rotation of the cylinder block performs one suctioning and discharging cycle, and continuous pumping operation can be achieved by rotating the shaft connected to the cylinder block.

Handling  Hydraulic oil  For pressures of up to 7 MPa {70 kgf/cm 2}, use a general-purpose hydraulic oil (R&O) or wear-resistant hydraulic oil equivalent to ISO VG32 to 68.  For pressures higher than 7 MPa {70 kgf/cm2} use wear-resistant hydraulic oil equivalent to ISO VG32 to 68.  Operate the unit in an environment where both the following conditions are satisfied: viscosity range from 15 to 400 mm2/s {cSt} and oil temperature from 0 to 60°C.  Contamination of the hydraulic fluid causes pump trouble and reduces the service life, so pay due attention to controlling contamination and ensure that it goes no higher than NAS contamination class 9.  Installation and alignment  Ensure that the eccentricity of the drive shaft and pump shaft is no greater than 0.05 mm (TIR), and run the pump with no force acting perpendicularly on the pump shaft.  Misalignment between the shaft centers will cause damage to bearings and oil seals, generate noise and vibration, and lead to pump accidents.  Avoid crosswise drive using a belt, chain or gears (it will cause noise generation or damage to the bearings).  Filters  Use a suction filter with 150 meshes per inch at the inlet side.  In the return line to the tank at the discharge side, use a line filter with a filtration accuracy of 25 μm or better.  For discharge pressures of 14 MPa {140 kgf/cm 2} and greater, use a line filter with a filtration accuracy of 10 μm.

Handling  At start  Check that the pump rotates in the direction of the arrow showing the direction of rotation.  When the pump is driven for the first time, turn the power switch to the motor on and off a few times to let the air out of the piping and then run it continuously at full speed. Noise may be observed until the air has been completely removed but this is not abnormal.  Suction pressure  Maintain the suction pressure no lower than −16.7 kPa {−125 mmHg}.  High suction pressures will generate cavitation and cause damage to the parts, noise, and vibration, resulting in a shorter pump service life.

Low quantity adjusting screw (QL) Width across flats: 26 (V15, V23, V38) : 39 (V70)

Adjust the discharge rate according to the relevant discharge rate adjustment graph by following the procedure below. (1) For the low quantity range, read the value for the desired discharge rate on the graph and turn the low quantity adjusting screw to set the scale position to the read value. (2) For the high quantity range, read the value for the desired discharge rate on the line corresponding to the value for the low quantity range on the graph and turn the high quantity adjusting screw to set the scale position to the read value. (3) When adjusting only the high quantity range, loosen the lock nut and adjust as described above. (4) When adjusting only the low quantity range, loosen the lock nut on the hight quantity adjustment screw and adjust the setting for the low quantity range as described above while holding the high quantity adjusting screw in place with a hex key. Example of adjustment Example: When adjusting the discharge rate of V15C at 1500 min −1 to 7 L/min for the low quantity range (QL) and 18 L/min for the high quantity range (QH)  From the discharge rate adjustment graph for V15C at 1500 min −1, first read the value for QL = 7 L/min, which is 4, and adjust the low quantity adjusting screw accordingly.  Then, read the value for QH = 18 L/min on the line for 4 of QL, which is 7, and adjust the high quantity adjusting screw accordingly.

VZ series Piston Pump Features  Highly intensified output

Adopting the cradle swash plate has achieved high pressure in a compact and light-weight body, resulting in increased output per unit weight.  Low noise While increasing the rigidity of the swash plate structure, the noise level has been substantially reduced thanks to the housing geometry resulting from the state-of-the-art measurement and analysis technologies.  High efficiency The spherical valve plate and optimum hydraulic balance realize stable and highly efficient operation over a broad range of operation conditions.  Long life Adopting the spherical valve plate with its superior abrasion resistance has improved the anti-contaminant characteristics.

Note: JR-G (T) 02 and JRP-G02 are recommended for the remote control system's relief valve. If the vent port is blocked, the pressure compensation structure does not work and the pump operates at a fixed pressure.

 Foot supports and piping flanges are not provided with the pump. Order them separately as required by referring to Pages S-2 to S-4. A-44

 The exact characteristics of the solenoid operated type combination control will be as shown to the right. To be more specic, even if the solenoid is turned on to switch to high pressure operation the discharge rate will not switch to the low quantity range (QL) until the pressure in the circuit reaches the pressure P1 that overcomes the bias spring force that inclines the swash plate.

(Scale graduation: 1°) Note: The high quantity adjustment range may be restricted due to the setting for the low quantity range. See the graphs on Page A-49 for details.

 Adjust the discharge rate according to the relevant discharge rate adjustment graph by following the procedure below. • For the low quantity range, read the value for the desired discharge rate on the graph and turn the low quantity adjusting screw to set the scale position to the read value. • For the high quantity range, read the value for the desired discharge rate on the line corresponding to the value for the low quantity range on the graph and turn the high quantity adjusting screw to set the scale position to the read value. • When adjusting only the high quantity range, loosen the lock nut and adjust as described above. • When adjusting only the low quantity range, loosen the lock nut on the hight quantity adjustment screw and adjust the setting for the low quantity range as described above while holding the high quantity adjusting screw in place with a hex key.  Example of adjustment When adjusting the discharge rate of VZ80C to 23 cm3/rev for the low quantity range (QL) and 75 cm3/rev for the high quantity range (QH) (1) From the discharge rate adjustment graph for VZ80C in combination control, first read the value for QL = 23 cm3/rev, which is 5°, and adjust the low quantity adjusting screw accordingly. (2) Then, read the value for QH = 75 cm3/rev on the line for 5° of QL, which is 11°, and adjust the high quantity adjusting screw accordingly.

The compatibility is indicated in the table as follows: Compatible: Installation compatibility provided (The external dimensions differ.) Note: *1 Design No. 10 uses a tongue shaft pump and, accordingly, a tongue shaft type motor is used. Since the motor is not compatible with the motor (key shaft type) used in the current design, it is not possible to replace the motor alone. When replacing the pump alone, use V8A1RXT-20. Note: The motor and pump are directly coupled. If it is difficult to decouple them, replace them as a set. <Time line of design numbers> (9: Models with actual production history) Design No. 10
