Description
Technical field
The utility model is related to a kind of plunger, and in particular to a kind of hollow plunger.
Background technology
In the prior art, the plunger displacement pump and motor of huge discharge, because of plunger preponderance in itself, running speed is too fast easily
Shake is produced, the efficiency of pump is leveraged.
The content of the invention
Goal of the invention：The purpose of this utility model is to overcome deficiency of the prior art, there is provided one kind operates steadily,
Not by the hollow plunger of plunger weight.
Technical scheme：In order to solve the above-mentioned technical problem, hollow plunger described in the utility model, it includes plunger sheet
Body, oilhole is provided with the middle part of the plunger body, and cavity, the oilhole outer wall are provided with the plunger body on the outside of the oilhole
Thickness between cavity inner wall and the thickness ratio between oilhole outer wall and plunger body outer wall are 1：（5.8-6.2）, the sky
Thickness between cavity outer wall and plunger body outer wall and the thickness ratio between oilhole outer wall and plunger body outer wall are 1：（2.8-
3.2）, the thickness between the oilhole outer wall and cavity inner wall and the thickness ratio between cavity outer wall and plunger body outer wall are 1：
（1.8-2.2）.
Thickness between the oilhole outer wall and cavity inner wall and the thickness ratio between oilhole outer wall and plunger body outer wall
It is 1：6.
Thickness between the cavity outer wall and plunger body outer wall and the thickness between oilhole outer wall and plunger body outer wall
Degree is than being 1：3.
Thickness between the oilhole outer wall and cavity inner wall and the thickness ratio between cavity outer wall and plunger body outer wall
It is 1：2.
Beneficial effect：Compared with prior art, its remarkable advantage is the utility model：The utility model structure setting is closed
Reason, sets the thickness and oilhole outer wall between cavity, and oilhole outer wall and cavity inner wall in the plunger body on the outside of oilhole
It is 1 with the thickness ratio between plunger body outer wall：（5.8-6.2）, thickness and oil between cavity outer wall and plunger body outer wall
Thickness ratio between hole outer wall and plunger body outer wall is 1：（2.8-3.2）, thickness between oilhole outer wall and cavity inner wall and
Thickness ratio between cavity outer wall and plunger body outer wall is 1：（1.8-2.2）, it is ensured that plunger is unaffected when in use, this knot
Structure is slim and graceful in the lower operation that runs at high speed, and shakes small, efficiency high, meets actual operation requirements.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Specific embodiment
The utility model is further described with reference to the accompanying drawings and examples.
As shown in figure 1, hollow plunger described in the utility model, it includes plunger body 1, in the plunger body 1
Portion is provided with oilhole 2, is provided with cavity 3 in the plunger body 1 in the outside of the oilhole 2, the outer wall of the oilhole 2 and the inwall of cavity 3 it
Between thickness and thickness ratio between the outer wall of oilhole 2 and the outer wall of plunger body 1 be 1：（5.8-6.2）, the outer wall of the cavity 3 and post
Thickness between the plug outer wall of body 1 and the thickness ratio between the outer wall of oilhole 2 and the outer wall of plunger body 1 are 1：（2.8-3.2）, it is described
The thickness ratio between thickness and the outer wall of cavity 3 and the outer wall of plunger body 1 between the outer wall of oilhole 2 and the inwall of cavity 3 is 1：（1.8-
2.2）.The utility model structure setting rationally, sets cavity, and oilhole outer wall and cavity in the plunger body on the outside of oilhole
Thickness between inwall and the thickness ratio between oilhole outer wall and plunger body outer wall are 1：（5.8-6.2）, cavity outer wall and post
Thickness between plug body outer wall and the thickness ratio between oilhole outer wall and plunger body outer wall are 1：（2.8-3.2）, outside oilhole
Thickness between wall and cavity inner wall and the thickness ratio between cavity outer wall and plunger body outer wall are 1：（1.8-2.2）, it is ensured that
Plunger is unaffected when in use, and this structure is slim and graceful in the lower operation that runs at high speed, and shakes small, efficiency high, meets actually used wanting
Ask.
The utility model provides a kind of thinking and method, and the method and approach for implementing the technical scheme are a lot, with
Only it is preferred embodiment of the present utility model described in upper, it is noted that for those skilled in the art,
On the premise of the utility model principle is not departed from, some improvements and modifications can also be made, these improvements and modifications should also be regarded
It is protection domain of the present utility model, each part being not known in the present embodiment can use prior art to be realized.
