Factors Affecting The Suction Height Of Reciprocating Pump
- Mar 04, 2018 -

The national pump testing center can detect the reciprocating pump, the power of the pump can reach 4000 kw, and can issue the national test report.

The factors affecting the suction height of reciprocating pump mainly include the temperature of liquid. Saturated vapor pressure of the transported liquid; Density of liquid; The diameter of the pipe; Local atmosphere; The flow rate of the liquid and the weight of the pump inlet check valve or the size of the spring elastic force. These factors show that the higher the density of the liquid, the smaller the suction height; The higher the saturation vapor pressure of the liquid, the smaller the suction height; The greater the local atmospheric pressure, the greater the suction height; The higher the temperature, the greater the saturation vapor pressure and the smaller the suction height; The higher the flow velocity, the higher the resistance loss and the greater the kinetic head, the smaller the suction height; The larger the diameter of the pipe, the smaller the resistance loss, the higher the suction height; The larger the weight or spring force of the inlet check valve, the greater the energy required for the liquid to open the check valve, so the suction height is smaller.
