The axial plunger pump has the advantages of high working pressure, stable flow, high efficiency, low energy consumption, compact structure and light weight, and is widely applied to the fields of seawater desalination, landfill leachate treatment, fire fighting and the like.
However, when the axial plunger pump is used, a certain pump inlet pressure needs to be ensured, and insufficient inlet pressure can cause cavitation in the pump and damage devices in the pump. Therefore, a delivery pump with a similar flow rate is often added before the axial plunger pump. Before starting the axial piston pump, the delivery pump must be first put into operation. The addition of a delivery pump makes the device more complex and increases the energy consumption.
