Abstract

The utility model provides a sliding bearing device of a magnetic drive pump. A corrugated buffer sleeve is arranged between a sliding bearing and a bearing base of the device. A corrugated buffer sleeve is arranged between the sliding shaft sleeve and a pump shaft. The elasticity of the corrugated buffer sleeve can effectively prevent the sliding bearing and the sliding shaft sleeve from compression deformation and damage due to thermal expansion caused by the sliding bearing device with too high temperature. Furthermore, a buffer cushion is respectively arranged between both ends of the sliding shaft sleeve and an axial direction positioning sleeve. The sliding bearing device takes certain buffering and protection effect when the sliding shaft sleeve is applied with axial direction impact force, and improves the service life of the pump.

Description

The Magnetic Drive Pump Sliding Bearing device

Technical field

The utility model relates to plain bearing arrangement, particularly the plain bearing arrangement of magnetic drive pump.

Background technique

Plain bearing arrangement is rotatably assorted and constitutes by being installed in the sliding bearing on the plain bearing housing and the sliding shaft sleeve put on axle being installed, prior art sliding bearing and plain bearing housing, sliding shaft sleeve with spool be the direct rigid installation of fixedlying connected.

Magnetic drive pump is a kind of the cooperation with interior magnet rotor by magnetic force by outer magnet rotor to drive interior magnet rotor rotation, and interior magnet rotor drives pump shaft and rotates, and makes a kind of pump of the vane rotor rotation work on the pump shaft in the pump housing.The pressure difference of in pump chamber, bearing owing to the impeller left and right sides, so the axial pressure of impeller action on pump shaft is bigger, it is big that pump shaft bears axial force, particularly when start, also can produce compression shock, sliding bearing and sliding shaft sleeve when particularly sliding bearing and sliding shaft sleeve pivoting friction cause thermal expansion, can cause sliding bearing and sliding shaft sleeve to split broken bad because of extruding when being subjected to a spool impact force action.

The model utility content

The purpose of this utility model is to improve at the shortcoming deficiency of above-mentioned prior art, provides a kind of rational in infrastructure, and is functional good, long service life, safe and reliable Magnetic Drive Pump Sliding Bearing device.

Technical characteristics of the present utility model is, is provided with the ripple cushion collar between sliding bearing and its bearing support; Between sliding shaft sleeve and pump shaft, be provided with the ripple cushion collar, utilize the elasticity of the slow cover of ripple can prevent effectively that to cause sliding bearing and sliding shaft sleeve extrusion to split broken bad because of thermal expansion that the plain bearing arrangement temperature causes when too high; In addition, be provided with buffering spacer, play certain buffer protection function when sliding shaft sleeve is subjected to axial impact force at two ends, the sliding shaft sleeve left and right sides and its axially locating inner room; Between sliding bearing and interior magnet rotor wheel hub, be provided with thrust button sliding bearing and thrust button plain bearing housing, the thrust button plain bearing housing is the seam disc type, thrust button sliding bearing and thrust button plain bearing housing seam are connected, the thrust button sliding bearing cooperates with the sliding bearing end face, on the interior ring fitting surface of thrust button sliding bearing and thrust button plain bearing housing, be provided with the ripple cushion collar, on the perpendicular end face of the stopping table that the thrust button plain bearing housing cooperates with the thrust button sliding bearing, be provided with buffering spacer, this thrust button plain bearing arrangement promptly plays the axial thrust positioning action, effectively prevent simultaneously thrust button sliding bearing eccentric wear and be hit, thermal expansion extrusion-deformation is split broken bad, increases the service life.

The utility model is rational in infrastructure, is provided with the ripple cushion collar and plays resilient protection on sliding bearing, sliding bearing sleeve, thrust button sliding bearing, and pump performance is improved, and is safe in utilization, the working life of having improved pump.
