Abstract
The utility model provides a mine submersible electric pump with a lower bearing seat being of a side sealing structure, and belongs to the field of submersible electric pumps. The mine submersible electric pump comprises a motor assembly and a pump assembly which are vertically arranged on a base, the motor assembly comprises a winding stator core, a rotor, an upper bearing seat and a lower bearing seat, and the pump assembly comprises a pump shaft, a pump body and an impeller. The upper portion of the base is connected and fixed on the lower portion of an outer shell through a bolt, the upper portion of the outer shell is connected on an outgoing line box cover through a bolt, an outgoing line box is downwards connected with the upper bearing seat and a shell in a bolted mode, and an inner rabbet of the shell and an outer rabbet of the lower bearing seat are matched and are connected through a hex head screw. The outer rabbet of the lower bearing seat and an inner rabbet of a volute are matched and are connected through a hex head screw, a mechanical seal is arranged between the lower bearing seat and a sealing chamber cover, and the impeller is in connected to the pump shaft in a key mode. According to the mine submersible electric pump with the lower bearing seat being of the side sealing structure, the sealing effect of the lower bearing seat can be effectively improved, normal operation of the submersible electric pump is guaranteed, the strength and the impact resistance of the lower bearing seat are increased, and the service life of the pump is prolonged.
Description
Technical field
The utility model relates to a kind of Submerged Motor Pumps, and specifically a kind of step is the mining submersible electric pump of side sealing structure.
Background technique
At present, there are a lot of problems in mining submersible electric pump on project organization, such as the structure problem of step.Sealing together with the step of present mining diving pump only has with electric machine casing seam cooperation place, once this road sealing effect is bad, motor will burn out because of water inlet, thereby affect the normal operation of mining submersible electric pump, on the other hand, the step material that mining submersible electric pump is used is gray iron, the intensity of gray iron is general, this just makes often to occur the situation of step fracture in the normally used environment of mining submersible electric pump, thereby in the working life of reducing mining submersible electric pump, be also difficult to meet user's actual demand.
Summary of the invention
Technical assignment of the present utility model is for the deficiencies in the prior art, and it is the mining submersible electric pump of side sealing structure that a kind of step that can more effectively improve the working life of the sealing effect of step, the intensity that increases step and impact resistance, prolongation mining submersible electric pump is provided.
The utility model solves the technological scheme that its technical problem adopts:
A kind of step is the mining submersible electric pump of side sealing structure, comprise the electric machine assembly and the pump assembly that are arranged in up and down on base, described electric machine assembly includes winding stator core, rotor and upper and lower bearing support, and described pump assembly comprises pump shaft, the pump housing, impeller.Described base top is bolted is fixed on outer casing underpart, described shell upper is bolted on wire outlet box cover, the downward bolt of outlet box is connecting upper bearing bracket, housing, described housing inner stopper coordinates with step outer stopper, by hex screw, couple together, described step outer stopper coordinates with spiral case inner stopper, by hex screw, couples together, between step and sealing chamber cap, have mechanical seal, described impeller key is connected on pump shaft.
The material of described step is alloyed steel.
Compared with prior art, the beneficial effect producing is the mining submersible electric pump that a kind of step of the present utility model is side sealing structure:
The utility model is used the step of side sealing structure, there is double-layer seal effect, can more effectively improve the sealing effect of step, prevent that motor from burning out because of water inlet, guarantee the normal operation of Submerged Motor Pumps, adopt alloyed steel material simultaneously, can increase intensity and the impact resistance of step, increase the service life, meet user's actual demand.

In figure: 1. cable, 2. outlet box, 3. upper bearing bracket, 4. bearing, 5. shell, 6. housing, 7. have winding stator core, 8. rotor, 9. bearing, 10. step, 11. sealing chamber caps, 12. mechanical seals, 13. spiral cases, 14. impellers, 15. pump covers, 16. bases.
Embodiment
Below doing below in conjunction with 1,2 pairs of the utility model of accompanying drawing, specifically describe in detail.
By reference to the accompanying drawings 1,2, it is the mining submersible electric pump of side sealing structure that the utility model provides a kind of step, comprise the electric machine assembly and the pump assembly that are arranged in up and down on base 16, described electric machine assembly includes winding stator core 7, rotor 8, upper bearing bracket 3 and step 10, and described pump assembly comprises pump shaft, the pump housing, impeller 14.Described base 16 tops are bolted is fixed on shell 5 bottoms, described shell 5 tops are bolted on wire outlet box cover 2, the downward bolt of outlet box 2 is connecting upper bearing bracket, housing, described housing 6 inner stoppers coordinate with step 10 outer stoppers, by hex screw, couple together, described step 10 outer stoppers coordinate with spiral case 13 inner stoppers, by hex screw, couple together, between step 10 and sealing chamber cap 11, have mechanical seal 12, described impeller 14 keys are connected on pump shaft.The material of step is alloyed steel.
During mining submersible electric pump operation, this side sealing structure of step has realized step and housing, step and spiral case two seals effect, has greatly improved its sealing, has improved working life.
Its processing and fabricating of mining submersible electric pump that a kind of step of the present utility model is side sealing structure is simple and convenient, processing and fabricating shown in by specification accompanying drawing.
Except the technical characteristics described in specification, be the known technology of those skilled in the art.
