Abstract
A low-noise horizontal chemical shielding pump comprises a base, a pump body and a shielding motor, wherein the pump body and the shielding motor are transversely integrally mounted on the base. 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 a circulating 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 the horizontal shielding chemical industry of a kind of low noise electric pump.
Background technique
The common pipe electric pump is owing to using 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 the horizontal shielding chemical industry of a kind of low noise electric pump.
The object of the present invention is achieved like this: the horizontal shielding chemical industry of a kind of low noise electric pump comprises base, the pump housing and shield electric machine; The pump housing and shield electric machine laterally are connected and are installed on the base; The pump housing comprises import, outlet and impeller, and shield electric machine comprises housing, stator and rotor, and rotor comprises rotor shaft, and impeller is installed on the rotor shaft; Stator wherein and rotor adopt respectively high-quality stainless steel shielding sealing; Also comprise Circulation pipe, an end of this Circulation pipe and the outlet of the pump housing connect, and the tail end of the other end of Circulation pipe and shield electric machine housing connects.
Outlet at the pump housing is provided with radial perforation, is connected with pipe joint on the hole, and described Circulation pipe connects by the outlet of this pipe joint and the pump housing, is provided with filter screen in the pipe joint.
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 button, and this thrust button 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 button 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 Circulation pipe, 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 button 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 button friction surface hardness, the corresponding working life that has prolonged axle sleeve, bearing housing, thrust button.
