Abstract
The invention discloses a kind of axial plunger pump for improving sealing assembling structure.It includes pump case, rotary sealing appts and fore bearing；The rotary sealing appts are built in the pump case, and are installed on the inner side of the fore bearing and are isolated with working media with by the fore bearing.The working media is aqueous medium.The fore bearing is self-lubricating bearing.The present invention by the way that rotary sealing appts are built in pump case and isolates fore bearing and working media, can effectively improve the service life of fore bearing, reduces rotatory sealing oil leakage fault rate.Working media of the invention is particularly suited for water base hydraulic medium.
Description
Technical field
The present invention relates to a kind of axial plunger pump, and in particular to a kind of improvement seals the axial plunger pump of assembling structure.
Background technology
At present in hydraulic pump industry field, the rotatory sealing oil leak of axial plunger pump has become global problem, especially works as work
When making medium for aqueous medium, the leakage problem is more prominent.As shown in figure 1, it has been investigated that, axial plunger pump is water base
The problem of easy oil leak is primarily due to axial plunger pump in use in medium, before the direct invasion plunger displacement pump of aqueous medium 4
Bearing 2 and have a strong impact on its service life, cause leakage accident to occur.
The content of the invention
It is an object of the invention to provide it is a kind of improve sealing assembling structure axial plunger pump, with solve the deficiencies in the prior art it
Place.
The present invention is adopted the following technical scheme that：
Improve the axial plunger pump of sealing assembling structure, including pump case, rotary sealing appts and fore bearing；The rotatory sealing dress
Put and be built in the pump case, and be installed on the inner side of the fore bearing and isolate with working media with by the fore bearing.
Preferably, the working media is aqueous medium.
Preferably, the fore bearing is self-lubricating bearing.
The present invention by the way that rotary sealing appts are built in pump case and isolates fore bearing and working media, can effectively improve front axle
The service life held, reduces rotatory sealing oil leakage fault rate.Working media of the invention is particularly suited for water base hydraulic medium.
Brief description of the drawings
Fig. 1 is the partial structural diagram of existing axial plunger pump.
Fig. 2 is partial structural diagram of the invention.
In figure：
1-pump case；2-fore bearing；3-rotary sealing appts；4-aqueous medium.
The present invention is described in further detail in conjunction with drawings and Examples.
Specific embodiment
As shown in Fig. 2 the axial plunger pump for improving sealing assembling structure of the present invention, is to be applied in aqueous medium environment.
It includes pump case 1, rotary sealing appts 3 and fore bearing 2, and the rotary sealing appts 3 are built in pump case 1 and are installed on front axle
2 inner side is held, so as to fore bearing be isolated with aqueous medium 4.Additionally, the fore bearing 2 uses self-lubricating bearing.
The present invention prevents aqueous medium from directly being accepted with front axle by being built in rotary sealing appts in pump case and isolating fore bearing
Touch；Meanwhile, fore bearing uses self-lubricating bearing, meets use requirement of the axial plunger pump under water base hydraulic mixture condition,
And the service life of fore bearing is substantially increased, reduce rotatory sealing oil leakage fault rate.
