VZ series Piston PumpFeatures 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 noiseWhile 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 efficiencyThe spherical valve plate and optimum hydraulic balance realize stable and highly efficient operation over a broad range of operation conditions.

Long lifeAdopting the spherical valve plate with its superior abrasion resistance has improved the anti-contaminant characteristics.

Pressure adjustment range [Common to the pressure feedback method (CH) and solenoid operated method (CJ)]

The exact characteristics of the solenoid operated type combination control will be as shown to the right. To be more specific, 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.

Relationship between the protruding length of the discharge rate adjusting screw and the discharge rate (pressure compensator control)

The maximum discharge rate can be set to the desired value by turning the discharge rate adjusting screw at the side of the housing. Turning the adjusting screw clockwise decreases the discharge rate. Turning the adjusting screw counterclockwise increases the discharge rate.

(Scale graduation: 1°)

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 adjustmentWhen 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.

Discharge rate adjustment graph for VZ80C in combination control

The setting values indicated above may change slightly depending on the conditions of use (fluid temperature, hydraulic fluid type, etc.)For final fine adjustment, repeat the adjustment described above and achieve the setting appropriate for the actual application.
