Abstract
The invention belongs to the technical field of pump bodies and particularly relates to a shield electric pump. The shield electric pump comprises a shield motor and a pump body. The pump body is fixedly connected to the shield motor. The shield motor comprises a motor shell, an impeller and a rotating shaft. A front bearing block and a rear bearing block are arranged in the motor shell. A shaft sleeve and a bearing are arranged in each of the front bearing block and the rear bearing block. The two ends of the rotating shaft are connected with the bearing in the front bearing block and the bearing in the rear bearing block correspondingly. The impeller is located in the pump cavity and fixedly connected with the rotating shaft. The shield electric pump has the beneficial effects that the conveying efficiency is improved by removing independent circulating liquid, and waste is avoided; the direction of a liquid outlet is the same with that of the shaft, and the liquid outlet is conveniently installed in a pipeline to become part of the pipeline; and due to the wholly-sealed structure of the shell, the structure can be reliable, guide vanes and the bearing blocks are integrally designed, so that the structure is small and exquisite, and the occupied space is small.
Description
Technical field
The invention belongs to pump housing technical field, be specifically related to a kind of shielded electric pump.
Background technology
Universal shield electric pump in order to cool down motor and lubrication bearing must from impeller discharge main flow liquid draw a part of circulation fluid flow into motor individually circulate, cause the waste of the energy.Further, since the feature of centrifugal impeller, liquid flows to axially to suck, radially discharge, change the flow direction, it is impossible to keep consistent with pipeline direction, it is not easy to install and waste piping material, exhaust apparatus need to be additionally set when having gas or vaporizing liquid, pump otherwise will be caused to damage.Axial wheel can realize axially sucking and discharging, but because its limitation used can not substitute centrifugal impeller, most widely used in pump remains centrifugal impeller.
Summary of the invention
It is an object of the invention to provide a kind of shielded electric pump, pumped (conveying) medium can be introduced directly into motor internal and cool down and lubricate.
The invention provides following technical scheme:
A kind of shielded electric pump, including shield electric machine and the pump housing, the described pump housing is fixedly connected on described shield electric machine；
The described pump housing is provided with pump chamber；
Described shield electric machine includes motor casing, impeller and rotating shaft, front-end bearing pedestal and rear bearing block are set in described motor casing, it is respectively provided with bearing in described front-end bearing pedestal and rear bearing block, described rotating shaft two ends are connected with the bearing in described front-end bearing pedestal and rear bearing block respectively, described impeller is positioned at described pump chamber and fixing with described rotating shaft is connected, on outside described impeller, stator is set, described stator is connected with rotating shaft, described motor casing ecto-entad sets gradually stator assembly and rotor assembly, described rotating shaft is fixed in described stator module, it is provided with gap between described stator module and described rotor assembly, described shield electric machine afterbody arranges liquid outlet.
Preferably, described guide vane wheel is fixing with described rotating shaft is connected.
Preferably, described stator assembly and rotor assembly outside is respectively provided with housing.
Preferably, described rotating shaft arranges endoporus.
Preferably, described bearing is ceramic bearing, and described rotating shaft is pottery rotating shaft.
Preferably, described liquid outlet direction is the most consistent with described rotating shaft.
The invention has the beneficial effects as follows: by arranging stator outside impeller, the liquid medium that impeller is discharged is led in motor, during main flow flows, instead of the function of circulation fluid, motor is cooled down and has lubricated, finally flowed out by motor afterbody liquid outlet.The present invention improves transfer efficiency by cancelling single circulation fluid, it is to avoid waste；Liquid outlet direction is identical with axle, it is simple to be arranged in pipeline, becomes a part for pipeline；Shell all-sealed structure makes structure reliable, stator and the Integral design of bearing block, compact structure, takes up room little.Automatic aerofluxus can be realized time vertically-mounted, be especially suitable for carrying the liquid of easily vaporization.
