Abstract
The utility model discloses magnetic pump prevents rotor magnetic biasing mechanism, by key cooperation slidable mounting magnetic path seat cover on the interior disc of outer magnetic rotor cover, fixed mounting magnetic path on the disc in the magnetic path seat cover sets up magnetic path seat cover locking screw on outer magnetic rotor sheathes, corresponds locking screw and has seted up the fenestra on the link, is equipped with the plug screw constitution on this fenestra. When the magnetic pump is assembled, the locking screw is loosened, the magnetic block seat sleeve slidably mounted on the outer magnetic rotor sleeve axially slides under the action of magnetic attraction force between the magnetic ring of the inner magnetic rotor and the magnetic ring on the outer magnetic rotor seat sleeve, so that the magnetic ring on the outer magnetic rotor seat sleeve is axially and automatically aligned with the magnetic ring on the inner magnetic rotor, the magnetic deviation between the magnetic ring of the inner magnetic rotor and the magnetic ring of the outer magnetic rotor is eliminated, and then the locking screw is screwed tightly to fix the magnetic block seat sleeve and the outer magnetic rotor sleeve, so that the axial force generated by the magnetic deviation of the pump shaft and the drive shaft is eliminated, the operation of the pump shaft is more balanced, and the abrasion of a sliding thrust bearing of the pump shaft is reduced.
Description
Technical Field
The utility model discloses a magnetic drive pump, especially the inside and outside magnetic rotor cooperation of magnetic drive pump prevents magnetic declination mechanism.
Background
The magnetic pump comprises a pump body, a pump cover, a pump shaft, an impeller, an inner magnetic rotor, an outer magnetic rotor, an isolation sleeve, a connecting frame, a driving shaft and a driving shaft bearing box. The pump body and pump cover butt joint, the pump shaft passes through the slide bearing device and installs on the pump cover, interior magnet rotor fixed mounting is on the pump shaft axle head, link and pump cover butt joint, drive shaft bearing box and link butt joint, the drive shaft passes through antifriction bearing and installs on the drive shaft bearing box, outer magnet rotor fixed mounting is on the drive shaft axle head, outer magnet rotor corresponds the cooperation with interior magnet rotor, drives interior magnet rotor and pump shaft rotation.
In the prior art, because an inner magnetic rotor and an outer magnetic rotor are respectively arranged at the shaft ends of a pump shaft and a drive shaft, the axial positions of magnetic rings on the outer magnetic rotor and the inner magnetic rotor cannot be completely aligned in the assembling process due to the axial size of each part on a two-shaft system and the superposition of accumulated errors in the assembling process, namely, a magnetic ring on the outer magnetic rotor and a magnetic ring on the inner magnetic rotor are axially staggered to a certain extent, the magnetic deflection is generated between the magnetic ring of the outer magnetic rotor and the magnetic ring of the inner magnetic rotor, and in reality, 50-60 percent of magnetic pumps have the problem of different degrees of magnetic deflection, particularly, in the assembling process of a multistage magnetic pump, the phenomenon of magnetic deflection is more obvious because more parts are involved in the shaft system. Because the magnetic force of the outer magnetic rotor magnetic ring and the inner magnetic rotor magnetic ring is strong, the suction force is large, when the outer magnetic rotor magnetic ring and the inner magnetic rotor magnetic ring have magnetic deviation, large axial suction force or thrust force can be generated on the inner magnetic rotor and the pump shaft, so that the pump shaft sliding thrust bearing and the drive shaft bearing are subjected to large axial pressure, the jigger has blocking, the pump shaft vibrates greatly when the magnetic pump operates, the pump shaft thrust bearing and the sliding bearing are subjected to accelerated wear, the magnetic pump vibrates greatly, and the problem of insufficient magnetic torque occurs seriously, and the misjudgment of the inspection can be caused.
SUMMERY OF THE UTILITY MODEL
The utility model aims at not enough to improve above-mentioned prior art, provide a magnetic drive pump and prevent rotor magnetic deviation mechanism to solve the magnetic deviation and to the harmful effects that the pump power pump caused.
The utility model discloses magnetic pump prevents rotor magnetic biasing mechanism, by flat key sliding fit installation magnetic path seat cover on the interior disc of outer magnetic rotor cover, fixed mounting magnetic path on the disc in the magnetic path seat cover sets up magnetic path seat cover locking screw on outer magnetic rotor sheathes, corresponds locking screw and has seted up the fenestra on the link, is equipped with the plug screw constitution on this fenestra.
The utility model discloses when the magnetic drive pump assembly, will locking screw loosen, key cooperation slidable mounting the magnet block seat cover on the interior disc of outer magnet rotor cover axial slip under the magnetic attraction effect with interior magnet rotor magnetic ring, make the magnetic ring that outer magnet rotor seat sheathes in automatically adjust well with the magnetic ring axial on the interior magnet rotor, eliminate the magnetic deflection of interior magnet rotor magnetic ring and outer magnet rotor magnetic ring, then it is fixed with magnet seat cover and outer magnet rotor cover to twist locking screw tightly to eliminate pump shaft and drive shaft because of the axial force that magnetic deflection produced, make the pump shaft operation more balanced, alleviate the wearing and tearing of pump shaft slip thrust bearing, life extension.

Detailed Description
The utility model discloses magnetic pump prevents rotor magnetic deviation mechanism, by the magnetic path seat cover 2 that the parallel key sliding fit installed on the inner disc of outer magnet rotor cover 1, the magnetic path 21 of fixed mounting on the inner disc of magnetic path seat cover 2, set up magnetic path seat cover 2 locking screw 3 on outer magnet rotor cover 1, this locking screw 3 is used for fastening magnetic path seat cover 2 and outer magnet rotor cover 1, correspond locking screw 3 and set up fenestra 41 on link 4, be equipped with plug screw 42 on this fenestra and constitute; the locking screws 3 may be provided in a plurality of distributed arrangements.
The utility model discloses when the magnetic drive pump assembly, will locking screw 3 loosen, because magnetic block seat cover 2 is sliding fit with outer magnet rotor cover 1, and prevent changeing by slip flat key 22, magnetic block seat cover 2 carries out endwise slip under the magnetic attraction effect with the magnetic ring 51 of inner magnet rotor 5, make magnetic ring 21 on the outer magnet rotor seat cover 1 and the automatic alignment of magnetic ring 51 axial on the inner magnet rotor 5, eliminate the magnetic deflection of inner magnet rotor magnetic ring 51 and outer magnet rotor magnetic ring 21, then it is fixed with magnetic block seat cover 2 and outer magnet rotor cover 1 with locking screw 3 wrench tightening, thereby eliminate pump shaft 6 and drive shaft 7 because of the axial force that magnetic deflection produced, make the pump shaft operation more balanced, alleviate the wearing and tearing of pump shaft slip thrust bearing, and prolonged service life.
