Abstract
A low-noise pipeline shielding electric 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 is communicated with the housing of the shielding motor. A front end and a back end of a rotor shaft are respectively connected with a shaft sleeve and a bearing sleeve. An inner wall of the bearing sleeve is provided with a plurality of vertical grooves. A helical groove is connected between two vertical grooves. One end face of the bearing sleeve is provided with a plurality of radial through grooves which are communicated with the vertical grooves. An external surface of the shaft sleeve is provided with one layer of nickel-based alloy. According to the low-noise pipeline shielding electric pump, after the medium which is pressurized through the electric pump is filtered at a pump outlet through a filter screen, the medium is cooled in the motor through a cooling pipe, thereby effectively reducing noise. An inner surface of the bearing sleeve is provided with the helical grooves and straight grooves according to design. A nickel-based alloy layer is soldered on the surface of the shaft sleeve and a thrust plate, which contacts with the bearing sleeve. Sufficient lubrication and cooling of the medium can be obtained when the shaft sleeve and the thrust plate are matched with the bearing sleeve. Service life of the shaft sleeve, bearing sleeve and thrust plate is correspondingly prolonged.
