Abstract
The utility model discloses an improve sealed assembly structure's axial plunger pump. It includes pump case, rotary seal device and fore bearing, place in the rotary seal device in the pump case, and install in the inboard of fore bearing is in order to incite somebody to action the fore bearing is kept apart with working medium. Working medium is water base medium. The fore bearing is self -lubricating bearing. The utility model discloses a keep apart in the pump case and with fore bearing and working medium placing in the rotary seal device, can effectively improve the life of fore bearing, reduce rotary seal oil leak fault rate. The utility model discloses a working medium is particularly useful for water base hydraulic medium.
Description
Technical field
The utility model relates to a kind of axial plunger pump, is specifically related to a kind of axial plunger pump that improves sealing assembly structure.
Background technology
In hydraulic pump industry field, the rotatory sealing leakage of oil of axial plunger pump has become global problem, especially works as work at presentWhile being aqueous medium as medium, this leakage problem is more outstanding. As shown in Figure 1, find after deliberation, axial plunger pump is water baseIn medium, easily the problem of leakage of oil is mainly because of axial plunger pump in use, before aqueous medium 4 direct invasion plunger displacement pumpsBearing 2 and have a strong impact on its service life, causes leakage accident to occur.
Utility model content
The purpose of this utility model is to provide a kind of axial plunger pump that improves sealing assembly structure, to solve prior art notFoot part.
The utility model adopts following technical scheme:
The axial plunger pump that improves sealing assembly structure, comprises pump case, rotary sealing appts and fore bearing; Described rotatory sealing dressPut and be built in described pump case, and the inner side that is installed on described fore bearing is to isolate described fore bearing and working media.
As preferably, described working media is aqueous medium.
As preferably, described fore bearing is self-lubricating bearing.
The utility model, by rotary sealing appts being built in pump case and by fore bearing and working media isolation, can effectively improveIn the service life of fore bearing, reduce rotatory sealing oil leakage fault rate. Working media of the present utility model is particularly useful for water base hydraulicMedium.
Brief description of the drawings
Fig. 1 is the partial structurtes schematic diagram of existing axial plunger pump.
Fig. 2 is partial structurtes schematic diagram of the present utility model.
In figure:
1-pump case; 2-fore bearing; 3-rotary sealing appts; 4-aqueous medium.
Now in conjunction with the accompanying drawings and embodiments the utility model is described in further detail.
Detailed description of the invention
As shown in Figure 2, the axial plunger pump of improvement sealing assembly structure described in the utility model, is to be applied to aqueous medium ringIn border. It comprises pump case 1, rotary sealing appts 3 and fore bearing 2, and this rotary sealing appts 3 is built in pump case 1 and installsIn the inner side of fore bearing 2, thereby fore bearing and aqueous medium 4 are isolated. In addition, this fore bearing 2 adopts self-lubricating bearing.
The utility model makes the aqueous medium can not be directly and front axle by rotary sealing appts being built in pump case and isolating fore bearingAccept tactile; Meanwhile, fore bearing adopts self-lubricating bearing, has met the use of axial plunger pump under water base hydraulic medium operating mode and has wantedAsk, and greatly improved the service life of fore bearing, reduced rotatory sealing oil leakage fault rate.
