Abstract
A low-noise electric pipeline shielding pump comprises a pump body, a shielding motor and a cooling pipe. One end of the cooling pipe is communicated with an outlet of the pump body, and the other end of the cooling pipe is communicated with a casing of the shielding motor. The front end and the rear end of a rotor shaft are respectively connected with a shaft sleeve and a bearing bush. A plurality of vertical grooves are arranged on the inner wall of the bearing bush, spiral grooves are connected among the vertical grooves, a plurality of radial through grooves arranged on one end face of the bearing bush are communicated with the vertical grooves, and a nickel-based alloy layer is arranged on the outer surface of the shaft sleeve. A medium generating pressure through the electric pump is filtered by a filter screen from an output of the pump body and then flows into the motor to be cooled through the cooling pipe, and noise is reduced effectively. The spiral grooves and the straight grooves are designed on the inner surface of the bearing bush, the nickel-based alloy layer is welded on the contact surface between the shaft sleeve and a thrust plate and the bearing bush in a sprayed manner and is matched with the bearing bush to be sufficiently lubricated and cooled by the medium, and correspondingly, the service lives of the shaft sleeve, the bearing bush and the thrust plate are prolonged.
Description
Technical field
The present invention relates to a kind of electric pump, particularly a kind of low-noise pipeline shielding electric pump.
Background technique
The common pipe electric pump is owing to use mechanical seal, causes fed sheet of a media leakage, befouling environment, operational reliability poor, difficult in maintenance, and traditional electric pump to motor radiating, can produce noise problem by driven by motor fan blade High Rotation Speed, and the vibration of electric pump is obvious.
Summary of the invention
Purpose of the present invention is to provide a kind of low-noise pipeline shielding electric pump.
The object of the present invention is achieved like this: a kind of low-noise pipeline shielding electric pump comprises the pump housing and shield electric machine; The pump housing comprises import, outlet and impeller, and shield electric machine comprises housing, stator and rotor, and impeller is installed on the rotor shaft; Described stator and rotor adopt respectively high-quality stainless steel shielding sealing; Also comprise cooling tube, an end of this cooling tube and the outlet of the pump housing connect, and the tail end of the other end of cooling tube and shield electric machine housing connects.
Outlet(discharge) flange at the pump housing is provided with radial direction through hole, and the outside, hole is connected with reducing T, and the inboard, hole is provided with filter screen; One end and the reducing T of described cooling tube connect.
Rear and front end at rotor shaft is connected with respectively the sliding bearing pair that is comprised of axle sleeve and bearing housing; Be interval with many vertical slots that axially connect on the inwall of bearing housing, be connected with spiral chute between each vertical slot, an end face of bearing housing be provided with many radially groove be communicated with each vertical slot; The outer surface of axle sleeve is provided with one deck nickel-base alloy.
The inner of described sliding bearing pair is connected with thrust plate, and this thrust plate is provided with one deck nickel-base alloy at the surface of contact of itself and sliding bearing pair.
Described bearing housing is the graphite shaft bearing sleeve.
The described thickness that is arranged on the nickel-base alloy on the axle sleeve is no less than 0.4mm.
The described thickness that is arranged on the nickel-base alloy on the thrust plate is no less than 0.3mm.
The tail end of described shield electric machine housing is connected with bleed valve.
That the present invention adopts is totally-enclosed, the unique texture of machinery-free sealing.Rotor adopts respectively shield gasket of high-quality stainless steel, work has produced the medium of pressure after the filtration of pump housing outlet process filter screen through electric pump, enter the motor internal cooling through cooling tube, thereby solved the common pipe electric pump because using mechanical seal to cause the problems such as fed sheet of a media leakage, befouling environment, operational reliability be poor, difficult in maintenance, effectively reduce the noise problem that traditional electric pump produces to motor radiating because of driven by motor fan blade High Rotation Speed, and reduced the oscillation phenomenon of electric pump.The rotating part of electric pump then adopts the graphite shaft bearing sleeve to support, lubricate with fed sheet of a media; Graphite shaft bearing sleeve friction surface has designed unique lubrication spiral chute and straight trough according to the water flow rotary direction, the direct contact friction surface spraying weld of axle sleeve and thrust plate and bearing housing precise finish behind the nickel-base alloy, with can obtain medium sufficient lubrication cooling after bearing housing cooperates, also can improve axle sleeve and thrust plate friction surface hardness, the corresponding working life that has prolonged axle sleeve, bearing housing, thrust plate.
