Description
Technical field
The utility model relates to a kind of centrifugal pump.
Background technique
Existing centrifugal pump comprises base, the pump housing, impeller and motor, and the described pump housing and motor are located on base, and described motor is provided with main shaft, and described impeller to be arranged in the pump housing and to be connected with one end of main shaft, and described main shaft is provided with mechanical seal device.Existing centrifugal pump has the following disadvantages: one is because the weight of the pump housing is large, mobile very inconvenient; Two is that existing mechanical seal device comprises stationary ring, rotating ring, drive sleeve and spring, the phenomenon of drive sleeve fracture in use often occurs, affects the quality of mechanical seal structure; Three is existing centrifugal pump impeller structure not science, a moment started, and because impeller needs the moment of torsion that overcomes comparatively greatly, very easily causes burning of motor, affects its working life.
Model utility content
The purpose of this utility model provides a kind of long service life for above-mentioned situation exactly, and mechanical seal quality is good, and is convenient to the centrifugal pump of movement.The purpose of this utility model realizes by following scheme: a kind of moveable centrifugal pump, comprise base, the pump housing, impeller and motor, the described pump housing and motor are located on base, described motor is provided with main shaft, described impeller to be arranged in the pump housing and to be connected with one end of main shaft, described main shaft is provided with mechanical seal device, it is characterized in that described base bottom both sides are provided with movable pulley, is convenient to mobile, described mechanical seal device comprises the rotating ring be arranged on main shaft and the stationary ring be arranged in machine envelope seat, the contact end face that stationary ring and machine seal seat forms primary sealing area, the side end face that described rotating ring contacts with stationary ring arranges depressed part, this depressed part end face corresponding to stationary ring matches formation secondary sealing area, the outer peripheral surface of described rotating ring arranges groove, spline sheet is set in a groove, sheathed spring on spline sheet outer peripheral surface, rotating ring is pressed to stationary ring by spring, described rotating ring is made up of ethylene propylene rubber material, owing to increasing straight rotor at the outer peripheral surface of rotating ring, avoid the phenomenon of drive sleeve fracture in prior art, improve the quality of mechanism seals structure, described impeller comprises body, lobus sinister sheet and lobus dexter sheet, this body has axis, this axis inside is provided with the axis hole run through about this axis, keyway is provided with in this axis hole, the left surface of described body is provided with the multiple chutes outwards dispersed, the elongation line of each chute is all by the shaft axis of this axis, the right part of described lobus sinister sheet is provided with fixture block, described fixture block to be stuck in chute and can to move, described lobus sinister sheet is furnished with the Zola's spring making this lobus sinister sheet have the trend of close axis, described body right flank is provided with the receiving cavity of annular, described lobus dexter sheet slides and is arranged in receiving cavity, and lobus dexter sheet is sheathed on the right part of axis, and can horizontally slip along axis, described lobus dexter sheet is furnished with makes this lobus dexter sheet have right extension spring to left dislocation trend, a top nose is provided with in described receiving cavity, this top nose has the outer arm and inner arm that are parallel to each other, the left end of this outer arm and the left end of this inner arm are coupled together by link arm, described link arm is hinged in receiving cavity, the right-hand member of described outer arm is fixed with weighted spherical ball, the right-hand member of described inner arm withstands on the left surface of lobus dexter sheet, the two ends of described Zola's spring are connected on lobus sinister sheet and axis, the two ends of described right extension spring are connected on the left surface of lobus dexter sheet and the left surface of receiving cavity, the outer end of described chute is provided with outward extending through hole, because lobus sinister sheet is near axis, lobus dexter sheet is near the left side wall of receiving cavity, thus there is less external diameter and less thickness, then the moment of torsion overcome needed for is less, reduce the probability of motor damage.The utility model has long service life, and mechanical seal quality is good, and is convenient to the features such as mobile.
