Abstract
The utility model relates to an axial force balancing device for a single-step cantilever petrochemical process pump, which relates to a pump. A bearing body is internally provided with a paired angle contact ball bearing which is internally provided with a main spindle, an angle contact ball bearing is arranged between the paired angular contact ball bearing and an impeller, the angle contact ball bearing is a great pressure angle contact ball bearing having an angle of 40 degrees, the load in the axial positive and negative directions is supported by the paired angle contact ball bearing and the serially connected angle contact ball bearing, so that the load of a simple bearing is reduced, the bearings are not easy to be damaged, the service life is long, and the operation is stable and reliable; and the utility model is applicable to the single-step cantilever petrochemical process pump.
Description
Technical field
The utility model relates to the pump class, is a kind of single-stage cantilever petrochemical industry process pump axial thrust balancing devices specifically.
Background technique
We know that existing single-stage cantilever petrochemical industry process pump axial thrust balancing devices is to be provided with the pairing angular contact ball bearing in bearing support.This single-stage cantilever petrochemical industry process pump axial thrust balancing devices, owing to be provided with the pairing angular contact ball bearing separately, axially positive and negative direction load relies on the pairing angular contact ball bearing to bear fully, the pairing angular contact ball bearing is fragile, has a strong impact on normal operation.
Summary of the invention
The technical problem that the utility model solves is, solving axial positive and negative direction load relies on the pairing angular contact ball bearing to bear fully, the pairing angular contact ball bearing is fragile, have a strong impact on the problem of normal operation, provide a kind of bearing not fragile, the single-stage cantilever petrochemical industry process pump axial thrust balancing devices that turns round reliable and stable.
The technical solution of the utility model is: be provided with the pairing angular contact ball bearing in the bearing support, be provided with main shaft in the pairing angular contact ball bearing, the main structure characteristics are to be provided with angular contact ball bearing between pairing angular contact ball bearing and the impeller.
As further improvement of the utility model: angular contact ball bearing is the large pressure angle contact ball bearing, and its angle is 40 °.
The beneficial effects of the utility model are, owing to be provided with angular contact ball bearing between pairing angular contact ball bearing and the impeller, axially positive and negative direction load is born jointly by the angular contact ball bearing of pairing angular contact ball bearing and tandem arrangement, reduced the load of single bearing, bearing is not fragile, long service life, it is reliable and stable to turn round.The utility model is applicable to single-stage cantilever petrochemical process pump.
