Abstract
The utility model relates to a magnetic pump, which comprises an impeller, a magnetic driver and a mechanical bearing which are sequentially arranged in a pump housing and penetrate through a driving shaft, and the magnetic driver comprises an inner magnetic rotor, an outer magnetic rotor and a distance sleeve. The utility model is characterized in that a rotating shaft is also provided with a circular permanent magnetic sleeve, the lower part of the rotating shaft is correspondingly provided with a magnetic block which is same with a magnetic pole which is relative to the circular permanent magnetic sleeve. The utility model has less power consumption and can achieve the requirement of the large power magnetic pump.
Description
The utility model relates to a kind of pump, particularly a kind of magnetic drive pump.
The utility model is the improvement invention to the magnetic drive pump that contains mechanical bearing.Be provided with magnetic driver though contain the magnetic drive pump of mechanical bearing, have advantages such as relative efficiency height, power consumption are little,, then have the shortcoming that power consumption is big, efficient is not high for powerful magnetic drive pump.
The purpose of this utility model is that a kind of efficient of design is higher, and power consumption is littler, the magnetic drive pump that power accommodation is wider.
The utility model is achieved in that it comprises order is provided with in the pump case the impeller that passes transmission shaft, magnetic driver and mechanical bearing, magnetic driver comprises interior magnet rotor, outer magnet rotor and spacer, also be provided with the permanent magnetism cover that goes in ring on rotatingshaft, rotatingshaft bottom correspondence is provided with described belt permanent magnetism overlaps the identical magnetic patch of relative magnetic pole.
Also be provided with magnetic suspension bearing on the above-mentioned magnetic transmission shaft.
Above-mentioned spacer is nonmetal spacer.
Above-mentioned belt permanent magnetism cover is the whole permanent magnetism cover that goes in ring.
Above-mentioned belt permanent magnetism cover is the belt permanent magnetism cover of piecemeal combination.
Above-mentioned belt permanent magnetism cover is rare-earth permanent magnet.
Above-mentioned magnetic patch is a rare-earth permanent magnet.
The utility model is provided with described belt permanent magnetism in rotatingshaft bottom correspondence and overlaps the identical magnetic patch of relative magnetic pole because rotatingshaft is provided with the permanent magnetism cover that goes in ring.The permanent magnetism cover that goes in ring produces suspension magnetic force with corresponding homopolarity magnetic patch, can significantly reduce the load-bearing of mechanical bearing, thereby make the efficient of magnetic drive pump higher, power consumption is littler, power accommodation is wider, the real powerful magnetic drive pump of manufacturing of realizing can realize really that also high-power magnetic drive pump adopts nonmetal spacer on magnetic driver simultaneously.
Below in conjunction with drawings and Examples the utility model is further described.
Fig. 1 is a structural representation of the present utility model.
Be provided with impeller 7, magnetic driver 2 and the mechanical bearing 6 that passes transmission shaft 10 among Fig. 1 in the pump case 1 in proper order, magnetic driver comprises interior magnet rotor 4, outer magnet rotor 3 and spacer 5, also be provided with the permanent magnetism cover 8 that goes in ring on rotatingshaft, rotatingshaft bottom correspondence is provided with described belt permanent magnetism overlaps the identical magnetic patch of relative magnetic pole 9.The magnetic patch certain repulsive force of generation that the permanent magnetism cover that goes in ring is identical with corresponding magnetic pole and reach suspension support to transmission shaft, thus the load of mechanical bearing alleviated.The ratio that mechanical bearing on the magnetic transmission shaft, magnetic suspension bearing can be set according to the needs of magnetic drive pump different capacity, the permanent magnetism cover that goes in ring accounts for respectively.
