OPERATING PRINCIPLE
- The PVA pumps are variable displacement vane pumps with piloted type hydraulic pressure compensator.
- They permit instantaneous adjustment of the flow rate according to the circuit consequence is that energy consumption is reduced and adequate in every cycle phase.
- The pumping group is complete with hydrostatic axial compensation distribution plates that improve the volumetric efficiency and reduce wear of the components.
- The pressure compensator operates with the principle of keeping the cam ring of the pumping group in the eccentric position with use of a piston controlled hydraulically by a pressure pilot stage.
- When the delivery pressure equals the pressure corresponding to the pilot stage setting, the cam ring is moved toward the center adjusting the flow rate to the plant requirements.
- In zero flow demand conditions, the pump delivers oil only to compensate any possible bleedings and pilotings, keeping the circuit pressure constant.
- The compensator response times are very restrained and such as to allow elimination of the pressure relief valve.
- Also available are the versions with maximum flow adjustment PVA***Q and with the device for selection of two independent pressure values with solenoid valve PVA***M

工作原理
- PVA泵是一种带先导式带压力补偿的变量叶片泵。
- 它允许根据系统要求自动调节其流量。该泵可在满足工作要求的同时降低能耗。
- 该泵采用具有静压轴向补偿功能的配油盘,能提高容积效率和减少部件磨损。
- 压力补偿工作原理是:在先导压力作用下,被拉柱塞移动,从而使油泵定子在某一位置平衡。
- 当输出压力与先导压力相等时,定子向中心移动,并使输出流量满足工作要求。
- 在输出流量为零的情况下,油泵的输出为补偿泄漏和以保持先导作用,而系统压力保持不变。
- 补偿器的响应时间 短,不会产生压力超调。
- 根据需要可提供 大变量可调型油泵PVA***Q和具有两路压力选择,带电磁阀的变量泵PVA***M。
