Description

TECHNICAL FIELD

[0002] The use pressure of the high-pressure plunger pump is generally between 10 MPa and 100 MPa. The high-pressure plunger pump belongs to a volumetric pump, and the volumetric pump achieves the purpose of conveying liquid by means of periodic change of a volume in a working chamber; mechanical energy of a prime mover is directly converted into pressure energy of the conveyed liquid by the pump; the capacity of the pump only depends on the volume change value of the working chamber and the change frequency of the working chamber in unit time, and is theoretically irrelevant to the discharge pressure. The reciprocating pump achieves periodic change of the volume in the working chamber by reciprocating movement of a piston in a liquid cylinder working chamber (or by periodic elastic deformation of a flexible element such as a diaphragm or a bellows in the working chamber). In structure, the working chamber of the reciprocating pump is separated from the outside by means of a sealing device, and is communicated or closed with a pipeline by a pump valve (an intake valve and a discharge valve).
