According to the multistage mining submersible electric pump, reliability of sealing is ensured, the service life of the mining submersible electric pump is prolonged, the multistage mining submersible electric pump has good anti-corrosion performance, and the practical requirement of a user is met.
Description
Technical field
The utility model relates to a kind of Submerged Motor Pumps, and specifically a kind of upper bearing bracket is the multistage 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 upper bearing bracket.Sealing together with the upper bearing bracket of present mining submersible electric 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, this has directly reduced the working life of mining submersible electric 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 acid, alkali mostly, these sewage can corrode the upper bearing bracket in mining submersible electric pump, the material of upper bearing bracket is generally gray iron, and the decay resistance of gray iron is general, in this process that just makes upper bearing bracket dispose of sewage at mining submersible electric pump, very easily corroded, be 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 providing a kind of and improve sealing effect, can more effectively reduce the upper bearing bracket that burn into extends the working life of mining submersible electric pump is the mining submersible electric pump of side sealing structure.
The utility model solves the technological scheme that its technical problem adopts:
A kind of upper bearing bracket is the multistage 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 with spiral case, outer casing underpart and links together, described shell upper is bolted on wire outlet box cover, the outer stopper of outlet box coordinates with the inner stopper on upper bearing bracket top, and the outer stopper of upper bearing bracket bottom coordinates with the inner stopper of electric machine casing.Described housing is also connecting step and sealing chamber cap downwards successively by bolt, between described step and sealing chamber cap, has mechanical seal, and described spiral case is connected with pump cover bolt, and described impeller key is connected on pump shaft.
The material of described upper bearing bracket is austenite 304 stainless steels.
A kind of upper bearing bracket of the present utility model be side sealing structure multistage mining submersible electric pump compared with prior art, the beneficial effect producing is:
The utility model adopts side sealing mode to realize two seals, guarantee the reliability of sealing, extended the working life of mining submersible electric pump, adopted austenite 304 stainless steels to make its outward appearance beautiful, there is good corrosion resistance, met user's actual demand.
