Relying on the reciprocating motion of the piston in the cylinder, the energy is transferred to the liquid in the form of static pressure to increase the kinetic energy of the liquid. The pump converts the mechanical energy into pressure energy and is called reciprocating pump. Reciprocating pump features are as follows: 1, for a wide range of pressure range When the discharge pressure fluctuations, the flow is relatively stable, reciprocating pump can be designed as EHV, HV, MV or LV. 2, high efficiency Reciprocating pump compressed liquid is a closed system, it is more efficient. 3, strong adaptability, a wider range of fluid volume. It can be used to deliver highly viscous liquids, but it is not advisable to deliver corrosive liquids and suspensions of solid particles directly. 4, more wearing parts, maintenance workload. 5, due to the reciprocating motion by inertial force limit, speed can not be too high, for large flow, the size and shape of the larger. 6, easy to pollute the process medium.
