Abstract
This utility model relates to the variable system of a kind of axial plunger pump, including end cap, variable cavity, variable piston and cylinder sleeve, described variable cavity is arranged at the inside of described end cap, and described variable piston stretches into described variable inside cavity, and described cylinder sleeve is arranged at the inwall of described variable cavity.The variable system of the axial plunger pump that this utility model provides, cylinder sleeve is added in variable inside cavity, without carrying out tufftride process in variable inside cavity, only described cylinder sleeve need to be carried out retrofit in variable inside cavity, will not occur because tufftride processes situations such as causing end cap deformation, processing technique is simple, and cost of manufacture is low.
Description
Technical field
This utility model relates to a kind of axial plunger pump, particularly relates to the variable system of a kind of axial plunger pump.
Background technology
The material that A11V (L) O series axial plunger pump end cap uses at present is spheroidal graphite cast-iron, as illustrated in fig. 1 and 2, plunger
Pump includes end cap 100 and variable piston 200, and end cap 100 is provided with variable cavity 300, in work process, and variable piston 200
Variable cavity 300 in end cap 100 moves back and forth, constantly rubs between variable piston 200 and variable cavity 300, institute
The hardness of variable cavity 300 on end cap 100 there to be higher requirement to anti-wear performance.
Present stage, generally use tufftride process of surface treatment that variable cavity inner wall is processed, but due to tufftride
Result is difficult to control to and is easily caused end cap deformation, impacts and easily cause the report of end cap part to later stage polish
Useless, production cost is higher；On the other hand, after later stage abrasion can only integral replacing end cap, maintenance cost is high.Therefore, it is necessary to carry
Go out a kind of novel axial plunger pump end cap, solve problem above.
This utility model provides the variable system of a kind of axial plunger pump, and processing is simple, meets while use requires big
Reduce greatly production and maintenance cost.
Summary of the invention
The technical problems to be solved in the utility model is to provide the variable system of a kind of axial plunger pump, and processing is simple, full
Foot uses while requiring and greatly reduces production and maintenance cost.
In order to solve above-mentioned technical problem, the utility model proposes the variable system of a kind of axial plunger pump, including end cap,
Variable cavity, variable piston and cylinder sleeve, described variable cavity is arranged at the inside of described end cap, and described variable piston stretches into
Described variable inside cavity, described cylinder sleeve is arranged at the inwall of described variable cavity.
Preferably, described end cap is made up of spheroidal graphite cast-iron.
Preferably, described variable cavity is arranged at described cover internal, in cylindrical cavity structure.
Preferably, described variable piston is column structure, stretches into the cavity inside of described variable cavity.
Preferably, described cylinder sleeve is become by alloy wear-resisting copper, in cylindrical shell.
Preferably, the size of the size of described cylinder sleeve and shape and described variable cavity and mating shapes.
Preferably, the cavity within described cylinder sleeve matches with the form and dimension of described variable piston.
Preferably, described cylinder sleeve is arranged at described variable cavity inner wall, is connected with described variable cavity by interference fit.
Compared with prior art, the beneficial effects of the utility model are:
1, the variable system of the axial plunger pump that this utility model provides, adds cylinder sleeve in variable inside cavity, it is not necessary to
Carry out tufftride process in variable inside cavity, only described cylinder sleeve need to be carried out retrofit in variable inside cavity, no
Can occur because tufftride processes situations such as causing end cap deformation, processing technique is simple, and cost of manufacture is low.
2, the variable system of the axial plunger pump that this utility model provides, by interference fit with described variable cavity even
Connect, after life-time service, if barrel wear, only need to disassemble the cylinder sleeve of abrasion, the cylinder sleeve more renewed, it is not necessary to change whole end
Lid, greatly reduces later maintenance cost.

Detailed description of the invention
In order to make those skilled in the art be more fully understood that the technical solution of the utility model, below in conjunction with the accompanying drawings with excellent
The utility model is described in further detail to select embodiment.
As shown in Figures 3 and 4, the variable system of a kind of axial plunger pump, including end cap 1, variable cavity 2, variable piston 3
And cylinder sleeve 4, described variable cavity 2 is arranged at the inside of described end cap 1, and described variable piston 3 stretches into described variable cavity 2
Inside, described cylinder sleeve 4 is arranged at the inwall of described variable cavity 2.
Described end cap 1 is made up of spheroidal graphite cast-iron, is used for protecting its internal structure, and with other structure phases of described plunger displacement pump
It is connected mutually.
It is internal that described variable cavity 2 is arranged at described end cap 1, in cylindrical cavity structure.
Described variable piston 3, in column structure, stretches into the cavity inside of described variable cavity 2, when described plunger displacement pump works
During state, described in described variable piston 3, do back and forth movement along described variable cavity 2.
Described cylinder sleeve 4 is become by alloy wear-resisting copper, in cylindrical shell, is arranged at described variable cavity 2 inwall, described cylinder sleeve
The size of the size of 4 and shape and described variable cavity 2 and mating shapes, described cylinder sleeve 4 is arranged in described variable cavity 2
After wall, the cavity within described cylinder sleeve 4 matches with the form and dimension of described variable piston 3.
This utility model uses cylinder sleeve structure, it is not necessary to carry out tufftride process in variable inside cavity, only need to be by described cylinder
It is enclosed within variable inside cavity and carries out retrofit, will not occur because tufftride processes situations such as causing end cap deformation, processing
Technique is simple, and cost of manufacture is low；On the other hand, described cylinder sleeve is connected with cavity interference, after life-time service, if barrel wear, only
The cylinder sleeve of abrasion need to be disassembled, the cylinder sleeve more renewed, it is not necessary to change whole end cap, greatly reduce later maintenance cost.
Compared with prior art, the beneficial effects of the utility model are:
1, the variable system of the axial plunger pump that this utility model provides, adds cylinder sleeve in variable inside cavity, it is not necessary to
Carry out tufftride process in variable inside cavity, only described cylinder sleeve need to be carried out retrofit in variable inside cavity, no
Can occur because tufftride processes situations such as causing end cap deformation, processing technique is simple, and cost of manufacture is low.
2, the variable system of the axial plunger pump that this utility model provides, described cylinder sleeve is connected with variable cavity interference, long
After phase uses, if barrel wear, only need to disassemble the cylinder sleeve of abrasion, the cylinder sleeve more renewed, it is not necessary to change whole end cap, greatly
Reduce greatly later maintenance cost.
The above is preferred implementation of the present utility model, it is noted that for the ordinary skill of the art
For personnel, on the premise of without departing from this utility model principle, it is also possible to make some improvements and modifications, these improve and profit
Decorations are also considered as protection domain of the present utility model.
