What Are Reciprocating Pumps?
Reciprocating pumps include piston pumps, metering pumps, and diaphragm pumps, commonly known as reciprocating pumps. It is a kind of positive displacement pump, which is widely used. A reciprocating pump is a conveying machine that directly supplies energy to a liquid in the form of pressure energy through the reciprocating motion of a piston. According to the driving mode, reciprocating pumps are divided into motor pumps (motor driven) and direct-acting pumps (steam, gas or liquid driven). [1]

- The main characteristics of the reciprocating pump are: high efficiency and wide high efficiency area. can reach very
- The flow of the reciprocating pump has nothing to do with the head, and is related to the size of the pump cylinder, the piston stroke and the number of reciprocations. The theoretical flow of the single-acting pump is QT = Asn. The actual flow of the reciprocating pump is smaller than the theoretical flow, and it decreases with the increase of the pressure head, which is due to leakage. The head of a reciprocating pump has nothing to do with the flow rate of the pump and the geometry of the pump, but is determined by the mechanical strength of the pump and the power of the prime mover.
- The reciprocating pump does not need to be filled with liquid when it is started, because the reciprocating pump has the ability of self-priming, but its
- (1) High exhaust pressure can be obtained, and the flow rate is independent of pressure. The suction performance is good and the efficiency is high.
- The traffic is not very stable. It is larger than the centrifugal pump at the same flow; the mechanism is complex; the amount of capital is large; it is not easy to maintain.
