Description
Technical Field
The utility model belongs to the technical field of it is sealed, relate to bearing seal assembly processing, especially an underwater pump thrust bearing seal assembly.
Background
Along with the rise of production cost, people pay more and more attention to the protection of the pump bearing, especially the underwater bearing working at high strength, and after water enters the underwater bearing, lubricating grease is deteriorated to cause the damage of the bearing. Although the technology is continuously improved, at present, a large proportion of pump bearings still adopt a framework oil seal technology of spring pretension to prevent lubricating grease from being polluted by impurities such as external water, dust and the like.
The spring-preloaded framework oil seal is a device invented by more than half century ago for protecting lubricating grease of an aircraft landing gear. Obviously, it is only suitable for intermittent operation, and for high-strength continuous underwater pumps, especially mud pumps, will be subject to bearing failure due to contamination of the lubricating medium, which in turn affects the working efficiency and increases the maintenance cost.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to overcome prior art's weak point, provide an adaptation high strength is strikeed, wear resistance is good, long service life's underwater pump thrust bearing seal assembly.
The utility model provides a its technical problem take following technical scheme to realize:
the utility model provides an underwater pump thrust bearing seal assembly, includes sealed apron, bearing seal group and white steel bushing, sealed apron lid dress in white steel bushing, bearing seal group set up between sealed apron and white steel bushing, bearing seal group constitute by three unit bearing seal, be first bearing seal, second bearing seal and third bearing seal respectively, first bearing seal and second bearing seal syntropy set up, second bearing seal and third bearing seal mirror image setting.
And the unit shaft seal comprises an axial rubber block and a radial rubber block which are integrally manufactured into a seamless structure.
And a supporting steel ring is coaxially inserted in the axial rubber block.
And, a T-shaped lug is integrally formed at the top of the axial rubber block.
And a groove is formed on the inner side of the tail end of the radial rubber block, and a reinforced rubber column is inserted in the groove.
The utility model has the advantages that:
the utility model discloses the innovation uses the subassembly structure in that underwater pump thrust bearing is sealed, utilizes sealed apron, bearing seal group and white steel sleeve formation sealing system, and bearing seal group comprises three unit bearing seal, is first bearing seal, second bearing seal and third bearing seal respectively, and first bearing seal sets up with the second bearing seal syntropy, and the second bearing seal seals the mirror image setting with the third bearing. The elastic property of the improved shaft seal structure is enhanced, the original shape can be recovered after the shaft seal structure is stretched or extruded and deformed, the improved shaft seal structure has high abrasion resistance, the effect of a pump (a pump with high pressure discharge) in a bin is better when the improved shaft seal structure is applied to the bin through practice, and the service life of the improved shaft seal structure can be prolonged by 3-4 times.
