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 requirements.The 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泵是一種帶先導(dǎo)式帶壓力補(bǔ)償?shù)淖兞咳~片泵。
- 它允許根據(jù)系統(tǒng)要求自動(dòng)調(diào)節(jié)其流量。該泵可在滿足工作要求的同時(shí)降低能耗。
- 該泵采用具有靜壓軸向補(bǔ)償功能的配油盤，能提高容積效率和減少部件磨損。
- 壓力補(bǔ)償工作原理是：在先導(dǎo)壓力作用下，被拉柱塞移動(dòng)，從而使油泵定子在某一位置平衡。
- 當(dāng)輸出壓力與先導(dǎo)壓力相等時(shí)，定子向中心移動(dòng)，并使輸出流量滿足工作要求。
- 在輸出流量為零的情況下，油泵的輸出為補(bǔ)償泄漏和以保持先導(dǎo)作用，而系統(tǒng)壓力保持不變。
- 補(bǔ)償器的響應(yīng)時(shí)間非常短，不會(huì)產(chǎn)生壓力超調(diào)。
- 根據(jù)需要可提供最大變量可調(diào)型油泵PVA***Q和具有兩路壓力選擇，帶電磁閥的變量泵PVA***M。
