Relying on the piston, plunger or diaphragm reciprocating pump cylinder alternately increase and reduce the workload transfer liquid or pressurized pump. Reciprocating pump is divided into reciprocating piston assembly according to the pump, piston and diaphragm 3 types. Application Features Reciprocating pump's main features are: ①high efficiency and effective regional. ② can achieve high pressure, pressure changes hardly affect the flow, thus providing a constant flow. ③ self-priming capacity, can transport liquid, gas mixture, but also specially designed transport mud, concrete. ④ greater flow and pressure pulsations, especially single-action pump, piston acceleration and intermittent drainage, pulse larger. Usually on the road (and sometimes in the way of suction pipes) the discharge pipe is set to provide a more uniform flow of gas. Multi-cylinder double acting pumps and pumps significantly increase non-uniform flow. ⑤ low speed, large size, structure, the pump is more complex, requires a special valve, manufacturing costs and installation costs higher. Piston pump is mainly used for water supply, hand pump piston pump is a widely used family life. Piston pump is used to provide high pressure liquid water source, such as printing press, high pressure water supply, it can be a piston pump oil field drilling mud pump, oil pump. Diaphragm pumps are particularly suitable for the delivery of highly toxic, radioactive, corrosive liquids. Gravel mills contain valuable liquids and solids. Diaphragm and piston pumps can be used as metering pumps.
