Abstract
The utility model discloses a quick variable response axial plunger pump which comprises a variable back cover, a swash plate and a plunger; an oil injection orifice is arranged on the variable back cover; and a balance oil groove matched with the oil injection orifice is arranged on the swash plate tightly clung to the variable back cover. The quick variable response axial plunger pump has reasonable structure and reduces the friction resistance overcome by rotating the swash plate by a variable mechanism in the variable back cover, therefore, the sliding friction coefficient is reduced, the variable sensitivity is improved, and the response speed is increased by 40%.
Description
Technical field:
The utility model relates to a kind of plunger pump.
Background technique:
Traditional cam-type axial piston pump reach the change discharge capacity by the inclination angle that changes swash plate, and the stroking mechanism wobbler in the variable bonnet need overcome very big force of sliding friction, causes speed of response slow, the work poor effect.
Summary of the invention:
It is a kind of rational in infrastructure that the purpose of this utility model is to provide, the fast variable response axial piston pump that speed of response is fast.
Technical solution of the present utility model is:
A kind of fast variable response axial piston pump comprises variable bonnet, swash plate, plunger, and it is characterized in that: the variable bonnet is provided with the oiling aperture, is provided with the balance oil groove that cooperates with the oiling aperture with the swash plate that the variable bonnet is close to.
Oiling aperture on the described variable bonnet runs through the variable bonnet, is positioned at the both sides of variable bonnet.
The utility model is rational in infrastructure, by injecting high pressure oil, reduces the required force of sliding friction that overcomes of stroking mechanism wobbler in the variable bonnet, reduces friction factor, and the sensitivity that has improved variable has promoted speed of response 40%.
Description of drawings:
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is an embodiment's of the utility model a STRUCTURE DECOMPOSITION diagrammatic sketch.
Fig. 2 is the configuration diagram of the utility model swash plate.
Embodiment
A kind of fast variable response axial piston pump comprises variable bonnet 1, swash plate 2, and plunger 3 is provided with oiling aperture 4 on the variable bonnet, be provided with the balance oil groove 5 that cooperates with the oiling aperture with the swash plate that the variable bonnet is close to.
Oiling aperture 4 on the described variable bonnet runs through variable bonnet 1, and is close to the both sides 6 at swash plate rear portion.
Balance oil groove on the described swash plate is close to the oiling aperture on the variable bonnet, make high pressure oil can inject the balance oil groove 5 at swash plate rear portion by oiling aperture 4, back at swash plate produces balance reaction thrust, also reduced simultaneously the coefficient of sliding friction, improve the sensitivity of variable, promoted speed of response.
