Novel high-pressure plunger pump

Abstract

The invention relates to the technical field of high-pressure plunger pump equipment, and provides a novel high-pressure plunger pump. The novel high-pressure plunger pump comprises a shell and a rearcover connected to the shell, wherein the shell is movably inserted with a transmission shaft, a plurality of transmission shaft splines are arranged on the transmission shaft, a cylinder body is sleeved on a section, located in the shell, of the transmission shaft, the cylinder body is provided with an inner hollow structure, an inner sleeve is connected to the inner side wall of the cylinder body, cylinder body splines are arranged on the inner side wall of the inner sleeve, and the cylinder body splines are meshed with the transmission shaft splines on the shell. According to the plunger pump, the defects in the prior art are overcome, the design is reasonable, the structure is compact, the problem that an existing plunger pump is too large in size is solved, and the problem that the rated pressure is not high is solved; a simple structure combination is adopted, so that the volume of the cylinder body, a ball hinge and a variable cylinder are reduce, meanwhile, the material of a plurality of parts is changed, on one hand, the volume of the plunger pump is reduced, so that the application range is enlarged, in addition, the service life of the plunger pump is prolonged, and theplunger pump has strong practicability.

Description

technical field [0001] The invention relates to the technical field of high-pressure plunger pump equipment, in particular to a novel high-pressure plunger pump. Background technique [0002] The plunger pump is an important device in the hydraulic system. It relies on the reciprocating movement of the plunger in the cylinder to change the volume of the sealed working chamber to realize oil absorption and oil pressure. The high-pressure plunger pump is the core component of high-end hydraulic equipment, known as the "heart" of the hydraulic system. The hydraulic system is one of the key components of the equipment manufacturing industry. It is widely used in agricultural and forestry machinery, chemical industry, textile machinery, energy industry machinery, metallurgical industry machinery, building materials industry machinery, machine tool industries, as well as military industry, aerospace, ships, etc. According to relevant statistics, 95% of construction machinery, 90...

AI Technical Summary

Problems solved by technology

[0008] Aiming at the deficiencies of the prior art, the present invention provides a new type of high-pressure plunger pump, which overcomes the deficiencies of the prior art, has a reasonable design and a compact structure, and solves the problems of the existing plunger pumps with too large volume and low rated pressure. Problem, the present invention adopts a simple structural combination, reduces the volume of the cylinder body, spherical joint and variable cylinder, and changes the materials of multiple parts at the same time. On the one hand, the volume of the plunger pump is reduced, and the scope of application is improved. In addition, It also improves the service life of the plunger pump and has strong practicability
