The main principle of selecting a hydraulic pump is the type of host equipment; the factors to be considered when selecting a hydraulic pump are mainly structural form, working pressure, flow rate, speed, efficiency, quantitative or variable, variable mode, life, prime mover type, noise, Pressure pulsation rate, self-priming capacity, compatibility with hydraulic oil, size, quality, economy, maintainability, etc.

   Selection of hydraulic pump types

   The selection of hydraulic pump type should be based on: system operating conditions, system working pressure and flow, working environment and other aspects.

   ⒈Select a single actuator according to the operating conditions of the system

If the speed is constant, choose a quantitative pump; in fast and slow operating conditions, choose a double pump or a multi-connected pump; when the variable speed operation requires pressure maintenance, choose a variable pump.

   ⒉Select according to the system working pressure and flow

For high pressure and large flow, choose plunger pump; choose gear pump or vane pump for medium and low pressure.

   ⒊Choose according to the working environment

The field operation and environment are poor, choose gear pump or plunger pump; indoor or fixed equipment or good environment choose vane pump, gear pump or plunger pump.

After the type of hydraulic pump is determined, its specifications and models are determined according to the pressure and flow required by the system.
