Description

Technical Field

[0001] This application relates to the field of plunger pumps, and more particularly to a plunger pump head that is easy to assemble efficiently. Background Technology

[0002] A piston pump is an important component of a hydraulic system. It relies on the reciprocating motion of a piston within a cylinder to change the fluid in the sealed working chamber, thus achieving oil suction and pressure. Piston pumps offer advantages such as high rated pressure, compact structure, high efficiency, and convenient flow rate adjustment, and are widely used in high-pressure, high-flow-rate applications where flow rate regulation is required.

[0003] The pump head is a crucial component of a plunger pump, primarily responsible for suction and discharge. The pump head is typically forged from a single piece of stainless steel, with suction and discharge valves arranged vertically. The suction port is located at the bottom of the pump head, while the discharge port is situated on the side, communicating with the valve chamber, thus simplifying the discharge piping system.

[0004] See Figure 1 The existing plunger pump head includes an air chamber 11, a connector 2, a connecting part 12, and a mounting part 13. The connector 2 is used to connect the plunger pump body. During installation, the air chamber 11, connector 2, mounting part 13, and connecting part 12 need to be connected by bolts, which results in low assembly efficiency and needs to be improved.
