Abstract
The utility model discloses a rubber bearing of a submersible pump, which is formed by a bearing body. A diversion groove is arranged on the inner surface of the bearing body, a sealing ring is arranged at the upper end of the bearing body, the sealing ring and the bearing body are continuous castings made of the same material, and the inner diameter of the sealing ring is slightly smaller than that of the bearing body. The rubber bearing of a submersible pump overcomes drawbacks of backflow of the diversion groove, and simultaneously resolves problems of low efficiency, high operation cost and abrasion of bearings and spindles of submersible pumps.
Description
Technical field
The utility model 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 in the utility model 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 technical scheme in the invention for solving the 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 technical scheme in the invention for solving the technical problem can also be:
The outer circumferential face of seal ring described in the utility model is a conical surface, is provided with annular dovetail slot at the inner peripheral surface of seal ring.
The beneficial effects of the utility model are:
Compared with prior art, the utility model 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.
