Abstract
The utility model relates to an axial balancing device for liquid pumps, wherein one end of a final stage impeller is provided with a disc-shaped balancing disc. One end of the final impeller is provided with a movable friction disc which is corresponding to a movable friction disc, one end of a pump body is provided with a static friction disc, and a spring is arranged between one end of the static friction disc and the pump body. The movable friction disc and the static friction disc can form a couple of rubbing pair, the rubbing pair not only can balance the axial force of a liquor pump, but also can prevent fluid leakage in the pump body. The utility model has sealing function and has the advantages of simple structure, compact structure, small size and low cost, and the utility model is suitable for various fluid pumps and is especially suitable for various multi-stage pumps, immersion pumps, etc.
Description
The utility model relates to the pump class, says it is a kind of liquid pump longitudinal balance device in detail.
We know that liquid pump can produce axial force at work, need Equilibrator to eliminate and balance.At present, the longitudinal balance device of liquid pump has balancing drum, Balance disc etc.Balancing drum is the cylindrical body that is installed in impeller end on the main shaft, and Balance disc is to be provided with disk on axle sleeve, is installed in impeller end on the main shaft, and the pump housing of impeller end is provided with and is connected with the liquid pump intake through the pump housing outside connecting tube.The aforesaid liquid pump shaft, is merely able to balancing axial thrust, and does not have sealing function owing to only be provided with single balancing drum, Balance disc to Equilibrator; Owing on the pump housing of impeller end, be provided with connecting tube, be connected with the liquid pump intake through the pump housing outside, complex structure is not and compact, and volume is big, the cost height.
The purpose of this utility model provides a kind of simple in structurely, compact, and volume is little, and is cheap, has the liquid pump longitudinal balance device of sealing function.
For achieving the above object, the utility model can adopt following scheme to realize:
The impeller end is provided with discoid Balance disc, and its main structure characteristics are that the impeller end is provided with the kinetic friction dish, corresponding with the kinetic friction dish, body end is provided with the static friction dish, is provided with spring between the static friction dish end and the pump housing, kinetic friction dish and the static friction dish friction pair that partners.
The utility model is because the impeller end is provided with the kinetic friction dish, body end is provided with the static friction dish, the axial force that kinetic friction dish and the static friction dish friction pair that partners, friction pair not only can the balance liquid pumps, and can prevent the leak of liquid that the pump housing is interior, have sealing function; Owing to need on the pump housing of impeller end, not be provided with connecting tube, be connected with the liquid pump intake through the pump housing outside, simple in structure, compact, volume is little, and is cheap.The utility model is applicable to various liquid pumps, is specially adapted to various multistage pumps, immersion pump etc.
