Abstract
A low-noise horizontal shielding chemical electric pump comprises a base, a pump body and a shielding motor. The pump body and the shielding motor which are integrated horizontally are equipped on the base. A shaft sleeve and a bearing sleeve are respectively connected on the front and the rear end of a rotor shaft. A plurality of vertical grooves are equipped on the inner wall of the bearing sleeve. Helical grooves are connected between every two adjacent vertical grooves. One end face of the bearing sleeve is provided with a plurality of radial through grooves which are communicated with each vertical groove. A nickel-based alloy layer is equipped on the outer surface of the shaft sleeve. By making a medium having pressure generated when passing through the electric pump discharged from an outlet of the pump body and filtered by a filter net and then enter the motor through a circulating pipe, the electric pump effectively alleviates the noise. Helical grooves and straight troughs are further designed on the inner surface of the bearing sleeve. The nickel-based alloy layer is respectively sprayed and welded on the shaft sleeve surface and a thrust disc surface both contacting the bearing sleeve. The medium can be fully lubricated and cooled through the match with the bearing sleeve. The service lifetimes of the shaft sleeve, the bearing sleeve and the thrust disc are correspondingly prolonged.
