The motor assembly comprises a winding stator iron core, a rotor, an upper bearing base and a lower bearing base, and the pump assembly comprises a pump shaft, a pump body and an impeller. The base is sequentially connected with a volute, the lower bearing base, a shell, the upper bearing base and a wire outlet box from bottom to top through bolts, a mechanical seal is arranged between the lower bearing base and a sealing chamber cover, the lower bearing base is further provided with the sealing chamber cover in bolt connection with the lower bearing base, the pump body is externally connected with a drainage pipeline, the impeller is the double-channel impeller and is fixed to a rotor shaft through a shaft shoulder, a key and a retaining screw, and the suction opening of the double-channel impeller is matched with an inner hole of the volute. The mine submersible electric pump can remarkably improve pollution discharge capacity, is good in abrasion resistance, can improve hydraulic performance and efficiency of a water pump, prolongs service life of the water pump, and can better meet practical needs of users.
Description
Technical field
The utility model relates to a kind of Submerged Motor Pumps, specifically a kind of mining submersible electric pump with two blade impeller.
Background technique
At present, there are a lot of problems in mining submersible electric pump on project organization, such as the structure problem of impeller.The impeller outlet width using in mining submersible electric pump is now narrow, crosses dirty ability, often occurs the phenomenon of foreign material clogging impeller runner, affects the normal operation of mining submersible electric pump, reduces the working life of water pump.On the other hand, in the normally used environment of mining submersible electric pump, the medium of user's discharge is the sewage that contains large solid particle mostly, these sewage impeller in mining submersible electric pump that can wear and tear, the material of impeller is generally spheroidal graphite cast iron, and the wear-resisting property of spheroidal graphite cast iron is not high, in this process that just makes impeller dispose of sewage at mining submersible electric pump, is very easily worn, thereby the hydraulic performance and the efficiency that reduce water pump, cannot meet user's actual demand.
Summary of the invention
Technical assignment of the present utility model is for the deficiencies in the prior art, provides a kind of impeller channel that improves to cross dirty ability, can more effectively reduce wear, improve the water pump mining submersible electric pump with two blade impeller in working life.
The utility model solves the technological scheme that its technical problem adopts:
A kind of mining submersible electric pump with two blade impeller, 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, upper bearing bracket and step, and described pump assembly comprises pump shaft, the pump housing, impeller.Described base is followed successively by spiral case, step, housing, upper bearing bracket, the connection of outlet box bolt from top to bottom, between described step and sealing chamber cap, there is mechanical seal, on described step, also has bolted sealing chamber cap, described pump housing external connection row waterpipe, described impeller is two blade impeller, by the shaft shoulder, key and stopping screw, be fixed on rotor shaft, the suction inlet of two blade impeller coordinates with spiral case endoporus.
Described two blade impeller adopts rich chromium cast iron material.
Compared with prior art, the beneficial effect producing is a kind of mining submersible electric pump with two blade impeller of the present utility model:
The utility model is used two blade impeller, has obviously improved the dirty ability of mistake of water pump, has extended the working life of mining submersible electric pump; Adopt rich chromium cast iron material to make it have good wear-resisting property, and then improve hydraulic performance and the efficiency of water pump, meet user's actual demand.
