The A4VSG series is a kind of swashplate - type axial - piston variable - displacement pump, designed for the high - efficiency hydraulic drive of open - circuit systems. It has displacements of 40, 71, 125, 180, 250, 355, 500, 750, and 1000. The nominal pressure is 350 bar, and the peak pressure is 400 bar.
Advantges and Features
- It is equipped with a swashplate angle indicator, which allows for easy monitoring of the pump's working state.
- It has excellent suction characteristics, ensuring a stable and reliable fluid supply.
- The control response is sensitive, enabling quick adjustment of the pump's output according to the system's needs.
- It adopts specially designed long - life, high - precision aviation - grade full - roller bearings, which can bear high loads and improve the service life of the pump.
- It features low noise, long service life, and an excellent power - to - weight ratio.
- With a through - shaft structure, it can be stacked into a combined pump to meet the requirements of different systems.
- The flow rate of the hydraulic pump is proportional to the rotational speed and displacement of the pump. The displacement can be adjusted steplessly by adjusting the inclination angle of the swashplate.
- It has a complete range of variable forms, such as DR/DRG constant - pressure control, LR hyperbolic constant - power automatic control, and EO2 electro - proportional control.
Here are the application areas of the A4VSG series pumps:
- Machine Tools: In the field of machine tools, the A4VSG series pumps provide precise and stable hydraulic power. They are used to drive various components such as tool feed systems, spindle drives, and clamping mechanisms. This ensures accurate machining operations and high - quality workpiece processing.
