Abstract
The invention discloses a rubber bearing of a submersible pump, which comprises a bearing body, wherein guide grooves are formed on the inner surface of the bearing body; a sealing ring is arranged at the upper end of the bearing; the sealing ring and the bearing body are continuously cast and made of the same materials; and the internal diameter of the sealing ring is slightly smaller than that of the bearing body. Accordingly, the rubber bearing of the submersible pump can overcome the defect in the backflow of the guide grooves and solve the problems that the submersible pump runs at low efficiency and high cost and the bearings and shafts of the submersible pump are prone to abrasion.
Description
Technical field
The present invention relates to a kind of submersible pump, especially a kind of rubber bearing of submersible pump.
Background technique
At present, the original rubber bearing of submersible pump of most of submersible pump.Because the backflow phenomenon of rubber bearing of submersible pump guiding gutter is in poor efficiency, the expensive running China's submersible pump always.Simultaneously, the anti-silt poor performance of original rubber bearing of submersible pump, the bearing of submersible pump and axle very easily produce wearing and tearing, the working life of reducing submersible pump.Notice of authorization number is CN2537840Y, the patent No. is the Chinese utility model patent of ZL02232264.7, the anti-silt rubber bush bearing of a kind of submersible pump is disclosed, though this rubber bearing of submersible pump has played the anti-silt effect of certain submersible pump, but effect is not very desirable, this rubber bearing of submersible pump does not solve the backflow phenomenon of rubber bearing of submersible pump guiding gutter, thereby the problem of submersible pump poor efficiency, expensive running is not resolved.Therefore, designing and a kind ofly can overcome the guiding gutter backflow phenomenon, solve the rubber bearing of submersible pump of submersible pump poor efficiency, expensive running and Underwater pump bearing, axle wearing and tearing simultaneously, is the present technical issues that need to address.
Summary of the invention
Technical problem to be solved by this invention provides and a kind ofly can overcome the guiding gutter backflow phenomenon, solves the rubber bearing of submersible pump of submersible pump poor efficiency, expensive running and Underwater pump bearing, axle wearing and tearing simultaneously.
The technological scheme that the present invention solves its technical problem is:
A kind of rubber bearing of submersible pump, the bearing support that is provided with guiding gutter by internal surface is formed, and is provided with seal ring in the upper end portion of bearing support, and seal ring is the identical continuous casting body of material with bearing support, and the internal diameter of seal ring is slightly less than the internal diameter of bearing support.
The technological scheme that the present invention solves its technical problem can also be:
The outer circumferential face of seal ring of the present invention is a conical surface, is provided with annular dovetail slot at the inner peripheral surface of seal ring.
The invention has the beneficial effects as follows:
Compared with prior art, the present invention has overcome the guiding gutter backflow phenomenon, has solved submersible pump poor efficiency, expensive running and Underwater pump bearing, axle wear problems simultaneously.Experimental result shows that the flow of submersible pump, lift improve 1-2% respectively, can make intrinsic pump efficiency improve 1.5-3%.Reduce energy consumption.Reduce the axial force of water pump greatly.Axial force can reduce about 15%.Just equal lift and improve 15%.Slow down the thrust-bearing frictional force of motor greatly.About 1 times of the working life of raising motor.
