Axial piston pump is supplied from stock. A4V is a variable displacement pump with axial plunger swashplate structure. It is used in hydraulic transmission system. The flow rate is directly proportional to the drive speed, and the displacement can be adjusted stepless. The output flow increases with the change of the inclination angle from the zero to the maximum. Changing the inclined angle of the inclined plate can change the flow direction smoothly. The appropriate matching range of the control and adjustment devices provides conditions for various control and adjustment functions. The pump is a two-way hydraulic relief valve to protect the side of high pressure oil to avoid overloading. These valves also play the role of the pressurized oil intake valve. In a standard variable pump, the A4V pump provides an auxiliary pump that acts as a booster subsidy and a pilot pump. A overflow valve is also installed to limit the maximum pressure of the turbocharging circuit. As a standard, it is recommended to filter the oil suction pipe in the pressurized pump. When necessary, the pressure line in the pressurized loop can be filtered through an oil filter installed on both sides of the pipeline.

Rexroth quantitative pump A4VSO specification 40 to 1000 axial piston swash plate structure of open loop 1 series and 3 series long bearing life controller and actuator product range (below) shaft structure with the specifications, can form a combined pump

Description:

1, the variable pump of the axial piston type inclined plate structure, the powerful shaft design, variable connection, multiple connection or connection with other oil pumps.

2. The new inclined board structure and the transmission shaft can bear the axial force and radial force, and use the large compensation piston to make the vibration noise and the flow vibration greatly improve.

3, spherical distribution, ball bearing and cylinder block self position reliability. It is applied to open circuit through energy saving pump control system, which can significantly improve power consumption, oil temperature rise, system accuracy and life.

4, inclined cylinder hole structure, the inlet velocity is small, the noise is low, the self-priming ability is good, the dynamic balance structure is reasonable, the rated speed is high.

5, the rigid structure and high speed and low friction structure make the oil pump high rated pressure and long life, and the performance is stable and reliable, and the efficiency is more ideal.

6, the variable form, the wide selection range, the use of modular design, so that the control mechanism is more diversified, the designer is easy to change the control function.

7. It is widely used in steel works, ships, petrochemicals, forging machine tools, ceramic press and metallurgical machinery.
