Abstract
The utility model discloses a kind of double-current ring sealing bearing bush watt seat sealing structure, including sealing bearing bush seat and generator's cover, sealing bearing bush seat and generator end to cover and be equipped with oil-through-hole, both are docked and connected by oil-through-hole；Sealing bearing bush seat oil-through-hole is in "convex" shaped, and bottom part aperture diameter is larger；Seal sleeve is embedded with sealing bearing bush seat oil-through-hole bottom, seal sleeve is arranged on the junction of sealing bearing bush seat and generator's cover, and outside is equipped with a circle sealing bearing bush mat.The beneficial effects of the utility model are, one seal sleeve of fluting installation, sleeve are sealed using o types circle at sealing bearing bush seat and generator's cover oil-through-hole, prevent sealing oil-pressure direct connects impact and seals mat oil-through-hole inner ring and break through mat from causing leakage.
Description
Technical field
It the utility model is related to a kind of double-current ring sealing bearing bush watt seat sealing structure.
Background technology
The double-current annular device that applicant uses, it is made of sealing bearing bush seat, sealing bearing bush, oil baffle and inner sealing lid etc.,
In addition to sealing bearing bush is installed in sealing bearing bush seat, remaining is the inner sealing lid sealing bearing bush seat with being bolted directly on end cap
And outer gear oil cap is having an electro-insulating rubber pad with the junction of end cap, gasket that the sealing of sealing bearing bush seat and generator's cover is leaned on
Son.
For a long time, sealing bearing bush mat damaged condition repeatedly occurs at the generator sealing bearing bush of two units of applicant, leads
Cause generator sealing oil pressure unstable, the unqualified phenomenon of hydrogen leak, hydrogen purity.In view of repeatedly sealing bearing bush mat damages feelings in the past
Condition is analyzed, the damage position of each sealing bearing bush mat always in identical position, the i.e. about 30 ° of positions in sealing bearing bush seat both ends downside,
And position at sealing bearing bush oil inlet, the position are Seal Oils by generator inner end cap oil outlet and sealing bearing bush seat oil inlet
Crucial junction, is exactly to be compressed to seal by sealing bearing bush mat around two hydraulic fluid ports, and this hydraulic fluid port is by the outside of sealing bearing bush seat
Mat simultaneously is considerably less, is easily broken through when oil pressure is risen, and causes oil leak and sealing oil pressure shakiness to cause hydrogen pressure unstable.
Utility model content
The purpose of this utility model is to solve shortcoming existing in the prior art, and proposes a kind of double-current ring sealing bearing bush
Watt seat sealing structure.
To achieve these goals, the utility model employs following technical solution：
A kind of double fluid ring sealing bearing bush watt seat sealing structure, including sealing bearing bush seat and generator's cover, sealing bearing bush seat and power generation
Generator terminal, which covers, is equipped with oil-through-hole, both are docked and connected by oil-through-hole；Sealing bearing bush seat oil-through-hole is in "convex" shaped, bottom part aperture diameter
It is larger；Seal sleeve is embedded with sealing bearing bush seat oil-through-hole bottom, seal sleeve is arranged on the connection of sealing bearing bush seat and generator's cover
Place, outside are equipped with a circle sealing bearing bush mat.
Preferably, sealing bearing bush seat bottom is equipped with a circle groove, and groove is embedded with sealing ring.
The beneficial effects of the utility model are that fluting installation one is close at sealing bearing bush seat with generator's cover oil-through-hole
Big envelope cylinder, sleeve are sealed using o types circle, prevent sealing oil-pressure direct connects impact sealing mat oil-through-hole inner ring and breaks through mat and cause from letting out
Leakage.
Brief description of the drawings
Fig. 1 is existing generator oil seal structure.
Fig. 2 is the structure diagram of the utility model.
Each mark meaning is in figure：1st, sealing bearing bush seat 2, sealing bearing bush 3, oil baffle 4, inner sealing lid 5, sealing bearing bush seat
6th, generator's cover 7, sealing bearing bush seat oil-through-hole 8, generator's cover oil-through-hole 9, seal sleeve 10, sealing bearing bush mat.
Embodiment
The following is a combination of the drawings in the embodiments of the present utility model, and the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.
With reference to Fig. 1, double-current ring sealing bearing bush watt seat sealing structure, including sealing bearing bush seat 5 and generator's cover 6, sealing bearing bush seat
Covered with generator end and be equipped with oil-through-hole 7,8, both are docked and connected by oil-through-hole；Sealing bearing bush seat oil-through-hole 7 is in " convex " word
Shape, bottom part aperture diameter are larger；Seal sleeve 9 is embedded with sealing bearing bush seat oil-through-hole bottom, seal sleeve is arranged on sealing bearing bush seat and power generation
The junction of generator terminal lid, outside are equipped with a circle sealing bearing bush mat 10.
Wherein, sealing bearing bush seat bottom is equipped with a circle groove, and groove is embedded with sealing ring.
The present apparatus leads to oily junction in generator sealing bearing bush seat and generator's cover, and reaming digging is carried out to sealing bearing bush seat side
Groove, leads to oil jacket cylinder to insert high intensity, and the sealing of o types circle is installed additional in sleeve both ends turning seal groove.
Whole sealing bearing bush mat bears relatively large oil shock power at sealing mat oil-through-hole, close in order to reduce
To the oil pressure of sealing bearing bush mat when oil sealing enters sealing bearing bush seat, the design in sealing bearing bush seat and generator's cover mainly by going out
The high intensity lining pipe of oily one insulation of spatial embedding forms logical oil jacket cylinder to reduce sealing oil pressure to the direct of sealing bearing bush mat
Impact.
The above, is only the preferable embodiment of the utility model, but the scope of protection of the utility model is not
This is confined to, any one skilled in the art is in the technical scope that the utility model discloses, according to this practicality
New technical solution and its utility model design are subject to equivalent substitution or change, should all cover the protection model in the utility model
Within enclosing.
