The Application Characteristic Of Reciprocating Pump

- Jul 13, 2018 -

The main characteristics of reciprocating pump are: 

① efficiency and high efficient area wide.

② can achieve a very High pressure, pressure changes almost does not affect the flow, thus providing a constant flow. 

③ has self-priming ability, can convey liquid, gas mixture, specially designed also can transport mud, concrete and so on. 

④ flow and pressure has a greater pulsation, especially the single action pump, due to the acceleration of the piston movement and the intermittent liquid discharge, the pulse is greater. Air chambers are usually set up on the discharge pipe (sometimes on the suction tube) to make the flow more homogeneous. The use of dual-acting pump and multi-cylinder pump can also significantly improve the flow of uneven. The 

⑤ speed is low, the size is big, the structure is more complex than the centrifugal pump, needs to have the specialized pump valve, the manufacture cost and the installment expense are high. Piston pump is mainly used for water supply, the manual piston pump is a widely used family life pump. Plunger pump is used to provide high-pressure liquid source, such as hydraulic pressure machine high-pressure water supply, it and piston pumps can be used as oil mine drilling mud pump, pump. Diaphragm pumps are particularly suitable for conveying highly toxic, radioactive, corrosive liquids, valuable liquids and liquids containing abrasive solids.

diaphragm pumps and plunger pumps can also be used as metering pumps.
