Abstract
A kind of pluger type hydraulic pump based on square plunger, comprise the rotor of pluger type hydraulic pump, rotor is laid with pilot hole, plunger coordinates with pilot hole to be installed, and the sectional shape of plunger and pilot hole is square, and the utility model makes the contact of plunger and pilot hole be that face contacts, in the working procedure of plunger pump, the contact movement in plunger and pilot hole face-face replaces traditional wire contact movement, reduces wearing and tearing and the scuffing of plunger face and pilot hole, increases the working life of plunger pump.
Description
Technical field
The utility model belongs to pluger type hydraulic pump technical field, particularly a kind of pluger type hydraulic pump based on square plunger.
Background technique
The structural type of oil hydraulic pump has multiple, and because plunger pump work under high pressure still can keep higher volumetric efficiency and total efficiency, its application widely.Different according to the layout of plunger and the direction of motion and transmission shaft relative position, plunger pump is divided into radial plunger pump and axial piston pump two class, its working principle is substantially identical, is all to rely on plunger reciprocating generation volume-variation in plunger hole to carry out oil suction and oil extraction.
The plunger of current plunger pump is the plunger of circular cross-section, corresponding plunger guide hole is circular, although the plunger of this circular section and plunger hole manufacturing easy, but circular plunger is linear contact lay with the coordinating of circular pilot hole of plunger, the contact stress of plunger and rotor is larger, plunger weares and teares more serious in long-term work process, cause the vent flow of hydraulic oil large, sometimes also there will be and scratch seriously, the coefficient of local friction in plunger and hole is too large, even occurs that plunger is stuck and causes the problem that pump cannot normally work.
Summary of the invention
In order to overcome the shortcoming of above-mentioned prior art, the purpose of this utility model is to provide a kind of pluger type hydraulic pump based on square plunger, reduces wearing and tearing and the scuffing of plunger and pilot hole, increases the working life of plunger pump.
In order to achieve the above object, the technical solution of the utility model is as follows:
Based on a pluger type hydraulic pump for square plunger, comprise the rotor 3 of pluger type hydraulic pump, rotor 3 is laid with pilot hole 2, plunger 1 coordinates with pilot hole 2 to be installed, and the sectional shape of plunger 1 and pilot hole 2 is square.
Advantage of the present utility model: make the contact of plunger and pilot hole be that face contacts, in the working procedure of plunger pump, the contact movement in plunger and pilot hole face-face replaces traditional wire contact movement, reduces wearing and tearing and the scuffing of plunger face and pilot hole, increases the working life of plunger pump.
Accompanying drawing explanation
Accompanying drawing is the assembling schematic diagram of the utility model plunger 1 and rotor 3.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail.
With reference to accompanying drawing, a kind of pluger type hydraulic pump based on square plunger, comprises the rotor 3 of pluger type hydraulic pump, rotor 3 is laid with pilot hole 2, and plunger 1 coordinates with pilot hole 2 to be installed, and the sectional shape of plunger 1 and pilot hole 2 is square.
Working principle of the present utility model is:
The contact of plunger 1 in pilot hole 2 reciprocatory movement is face contact, reduces wearing and tearing and the scuffing of plunger 1 and pilot hole 2; Simultaneously plunger 1 and the matching relationship of pilot hole 2 are conducive to reducing the leakage of pump hydraulic oil in the course of the work.
