Abstract
The utility model belongs to the technical field of electric pumps, and relates to a novel plastic submerged electric pump, which comprises a pump cover and a pump seat connected with the pump cover into a whole; the inside of the pump seat is provided with a motor; the inside of a motor shell of the motor is provided with a stator, a rotor and a rotating shaft; the bottom of the cylindrical motor shell is provided with a plastic cover which can be connected with a lower bearing block of an inner cavity to form a sealing oil chamber; a combination part between the plastic cover and a pump shaft in the sealing oil chamber is provided with a double mechanical seal; the end part of the pump shaft outside the plastic cover is provided with an impeller; and a sand prevention cover is arranged between the impeller and the plastic cover. The novel plastic submerged electric pump has the advantages that: the novel plastic submerged electric pump cannot be attacked by external sewage or wound by fibriform substances, the damage rate of the motor can be reduced, and the service life of the plastic pump can be prolonged.
Description
Technical field
The utility model belongs to the electric pump technical field, refers in particular to a kind of novel plastic Submerged Motor Pumps.
Background technique
Referring to Fig. 1: the kind of Submerged Motor Pumps is a lot, purposes is also very extensive, general existing diving plastic pump includes pump cover 10, pump seat 11 and place motor 1 in the pump seat, be provided with stator 3 in the motor casing of motor 1, the impeller 50 that rotor 2 reaches by its drive, bottom at pump seat 11, the below of motor 1 is provided with single mechanical end face seal 40, mechanical seal 40 is arranged between step 30 and the impeller 50 and is positioned at outside the motor 1, the mechanical seal 40 of this diving plastic pump is exposed in the water and contacts with sewage, be subjected to the invasion and attack of sewage, be easy to damage at short notice, rotate in water owing to impeller 50 in addition, fibrous thing is easy to be wrapped in the mechanical seal 40 in the sewage, destroy its sealability, make motor 1 water inlet and burn out, mechanical seal 40 damages and causes motor 1 to burn out accounting for diving plastic pump spoilage more than 70%, make its diving plastic pump short working life.
Summary of the invention
The purpose of this utility model provides a kind of invasion and attack that can not be subjected to extraneous sewage, can not twined by fibrous thing, can reduce the spoilage of motor, improves the sealability of plastics Submerged Motor Pumps and a kind of novel plastic Submerged Motor Pumps in working life.
The purpose of this utility model is achieved in that
The novel plastic Submerged Motor Pumps, include the pump seat of pump cover and coupled body, motor is housed in the pump seat, be provided with stator, rotor and rotatingshaft in the motor casing of motor, be provided with the vinyl cover that can be connected to form the sealing grease chamber with step in the inner chamber in the bottom of the motor casing of tubular, junction at indoor vinyl cover of sealing oil and pump shaft is provided with double mechanical seal, outside vinyl cover, the end of pump shaft is provided with impeller, is provided with the sand prevention lid between impeller and vinyl cover.
Above-mentioned step is connected in the motor casing.
Above-mentioned vinyl cover is bolted to connection on step.
Above-mentioned mechanical seal two ends are placed in the positioning groove of indoor upper bearing bracket of sealing oil and vinyl cover, are provided with Gask-O-Seal between positioning groove and the mechanical seal.
