Description

Technical Field

[0001] The utility model belongs to the technical field of plunger pumps, in particular to a hydraulically driven plunger pump. Background Art

[0002] The plunger pump is a key component in hydraulic systems. It relies on the reciprocating motion of the plunger within the cylinder, causing the volume of the sealed working chamber to change, thereby absorbing and compressing oil. Plunger pumps offer advantages such as high rated pressure, compact structure, high efficiency, and easy flow regulation. They are widely used in applications requiring high pressure, high flow, and where flow regulation is required, such as hydraulic presses, construction machinery, and ships.

[0003] In the prior art, publication number CN 221236834 U discloses a hydraulically driven vertical plunger pump comprising a pump body, a guide sleeve, a bracket, and a coupling assembly. The guide sleeve is fixedly connected to the upper surface of the pump body, a bracket is provided on the outer arc surface of the guide sleeve, a hydraulic cylinder is mounted on the upper surface of the bracket, a piston is provided at the driving end of the hydraulic cylinder, the piston is slidably connected to the inner wall of the guide sleeve, and a coupling assembly is provided at the junction of the hydraulic cylinder and the piston. The coupling assembly comprises a T-shaped sleeve, which is provided at the driving end of the hydraulic cylinder, a chuck is fixedly connected to the upper surface of the piston, and a groove is provided on the outer arc surface of the chuck. By providing the coupling assembly and the auxiliary assembly, the structural strength of the connection part of the plunger pump is improved, thereby reducing the problem of high stress and easy deformation of the bolts when bolt connection is used, which causes damage to the structure of the plunger pump, and further improving the stability of the plunger pump during actual use.

[0004] The existing hydraulically driven plunger pump connects the output rod of the hydraulic device to the piston of the plunger pump through multiple mounting bolts. The installation is very inconvenient and requires the use of tools for installation and disassembly. The operation is very inconvenient and seriously reduces the work efficiency. In addition, it is easy to affect the stability of the connection between the piston and the hydraulic rod due to some of the mounting bolts not being tightened tightly.

[0005] Therefore, there is an urgent need to improve the existing hydraulically driven plunger pump to solve the above-mentioned problems. Utility Model Content
