Principle Structure Of Piston Pump
Oct 30, 2018

PISTON pump piston reciprocating movement, so that the pump cavity working volume cycle changes, to achieve inhalation and discharge of liquids. Consists of a pump cylinder, a piston, a water inlet valve, an inlet and outlet pipe, a connecting rod and a transmission device. By driving the piston in the pump cylinder for reciprocating movement. When the piston upward movement, the inlet valve opens, the water enters the pump cylinder, at the same time the piston the water valve is closed, the piston upper part of the hydraulic is lifted upward with the piston, when the piston moves downward, the inlet valve closes, the valve on the piston opens, at the same time makes the pump cylinder under the chamber water pressure into the upper cavity, The water is continuously discharged from the outlet pipe. Piston pump is divided into single, double-acting, single, double, multi-cylinder type, horizontal, vertical, oblique, mobile, manual, foot, animal-style.

Piston Pump Flow q=0.71~6000 m 3/h, discharge pressure p2≤39.2 MPA, most cases p2≤24.5 MPa. The flow of the piston pump is determined by the pump cylinder diameter, the piston stroke and the reciprocating times of the piston per minute; the head depends on the characteristics of the device piping, the same piston pump flow is constant, and the head can be changed with the device piping characteristics. That is, raise the lift, and the flow is constant, only in the high-pressure zone, the flow slightly reduced.
