It relies on the reciprocating motion of the plunger in the cylinder to change the volume of the sealed working chamber to achieve oil suction and oil pressure. The plunger pump has the advantages of high rated pressure, compact structure, high efficiency and convenient flow regulation. The plunger pump is widely used in high pressure, large flow and flow regulation occasions, such as hydraulic presses, engineering machinery and ships. Among them, the reciprocating plunger pump needs to be supported and fixed with the help of a base before use.

Although the base of the above structure can achieve reliable installation and fixation of the reciprocating piston pump when in use, due to the fixed overall structure of the base, the base can only be used for reciprocating piston pumps of a specific size when in use, and the position of the mounting plate cannot be flexibly adjusted according to the actual size of the reciprocating piston pump, which makes the flexibility of the reciprocating piston pump base poor.
