Abstract
The invention discloses a pump body for a superhigh-pressure axial plunger pump. The pump body is formed in a way that a body of the pump body which is circular in shape is manufactured, a pentagram-shaped communication oil duct is designed in the body, the center of the body is designed with a connecting shaft through hole and the body is designed with an oil discharge outlet communicated with the pentagram-shaped communication oil duct. The pump body provided by the invention is reasonable in design and convenient to use, and improves the production efficiency.
Description
Technical field
The present invention relates to a kind of design of part of ultrahigh pressure axial plunger pump, particularly a kind of ultrahigh pressure axial plunger pump pump housing is applicable to ultrahigh pressure axial plunger pump.
Background technique
At present, traditional axial piston pump, many employings dish flow join oily mode, pump body structure is complicated, the processing technology difficulty is large, can not reach higher working pressure.
Summary of the invention
Problem to be solved by this invention is, overcomes the deficiencies in the prior art, and a kind of ultrahigh pressure axial plunger pump pump housing is provided.This pump housing is not only reasonable in design, and is easy to use, and the pump housing made by the stronger material of weldability, has stronger manufacturability, and processing is conventional machine tooling substantially, is convenient to batch production.
The technical solution used in the present invention is: the pump housing is shaped as circular pump housing body by making one, is designed with five-pointed star in it and is communicated with oil duct, and the body Center has the coupling shaft through hole, is designed with on the body to be communicated with the oil drain out of oil duct connection with five-pointed star and to consist of.During use, the present invention is connected into the former position of ultrahigh pressure axial plunger pump,, can reliable operation work.
Employing of the present invention, the pump housing of variation body structure are the overall construction design mode, the integrative-structure that each oil duct is interconnected, and processing is simple.Distinctive pump housing welding procedure cooperates with it, has good sealing, delivery side of pump pressure oil pressure can be brought up to the demand that 100MPa. satisfies system's ultrahigh pressure.
The selection of material of the present invention is extensive, adapts to different demands.Relative heat treatment method is also greatly simplified, and has reduced processing cost.
The invention has the beneficial effects as follows, rational in infrastructure, easy to use, adopt integrated type suction fuel tap flow mode, simplified design, manufacture cost has reduced much relatively.Available steel part has enlarged the range of choice of material simultaneously, is conducive to standardization and unitized work.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is plan view sectional structure schematic diagram of the present invention.
Fig. 2 is that left view of the present invention is along oil drain out center sectional structure schematic diagram.
Accompanying drawing number is: 1, body, 2, five-pointed star is communicated with oil duct, 3, the coupling shaft through hole, 4, oil drain out.
Embodiment
With reference to Fig. 1, Fig. 2, the pump housing is shaped as circular pump housing body 1 by making one, is designed with five-pointed star in it and is communicated with oil duct 2, and body 1 Center has coupling shaft through hole 3, is designed with on the body 1 to be communicated with the oil drain out 4 of oil duct 2 connections with five-pointed star and to consist of.During use, the present invention is connected into the former position of ultrahigh pressure axial plunger pump, can reliable operation work.
Employing of the present invention, the pump housing of variation body structure are the overall construction design mode, the integrative-structure that each oil duct is interconnected, and processing is simple.Distinctive pump housing welding procedure cooperates with it, has good sealing, delivery side of pump pressure oil pressure can be brought up to the demand that 100MPa. satisfies system's ultrahigh pressure.
The selection of material of the present invention is extensive, adapts to different demands.Relative heat treatment method is also greatly simplified, and has reduced processing cost.
