Abstract

The utility model relates to the field of magnetic force driving pumps. The coupling form of the magnetic force torque of an inner magnetic swivel and an outer magnetic swivel in the magnetic force coupling device of a magnetic force driving pump is a plane transfer form, which breaks through the traditional sleeve coupling form. An integral impeller and a bearing seat whose single side is sealed are adopted, which makes the structure of the whole pump simple and compact without leakage. The manufacture is convenient and the cost is obviously reduced. The power consumption is obviously reduced. The carrying capacity is enhanced. A higher power can be transferred. The utility model is suitable for being used in various industries, such as chemical industry, etc.

Description

Magnetic chemical pump

The utility model relates to the magnetic force driving pump technical field.

Known magnetic force driven centrifugal pump is made up of motor, magnetic force coupling device, the pump housing.Its magnetic force coupling device by inside and outside magnetic turn, separation sleeve and hitch form, separation sleeve is turned inside and outside magnetic isolated, the coupled mode that inside and outside magnetic is turned is for radially telescopic; Impeller and impeller shaft in its pump housing are separated from each other, link by coupling, and the bearing hole of its bearing support is a through hole.There are some shortcomings in such structure, and separation sleeve accuracy of manufacturing and technological requirement height involve great expense; The circular runout that impeller produces is bigger, increases power loss; Be difficult for forming liquid friction between axle and bearing, mechanical wear raises, and efficient reduces; Liquid might leak into this chamber of coupling device by bearing from pump chamber magnetic is produced harmful effect.Whole magnetic drive pump part is more, and structure is complicated, manufacture difficulty is bigger, and the cost height is difficult for promoting the use of.

The purpose of this utility model provide a kind of simple in structure, make convenient, cost is low, bearing capacity is strong, the more powerful magnetic force driving pump of mechanical efficiency high energy transmission, can be applicable to multiple industries such as chemical industry.

The technical solution of the utility model is achieved in that magnetic drive pump is made up of motor, magnetic force coupling device, the pump housing, its coupling device by inside and outside magnetic turn, bearing support and hitch constitute, the enclosed bearing support of single face that forms full-closed structure with pump case is turned inside and outside magnetic isolated, the surface that magnetic material in sticking embedding on inside and outside magnetic was turned all is respectively a plane, two planes are parallel to each other, and the shaft axis that inside and outside magnetic is turned is on the same straight line.When magnetic is turned outside the driven by motor because the effect that the same sex is repelled each other, there is a natural attraction between the sexes of magnetic, interior magnetic turn (being the integrated type impeller) will produce to rotate synchronously and carry out fed sheet of a media.

Owing to cancelled the separation sleeve that manufacture difficulty is big, cost is high in the such scheme, cost is reduced, it is convenient to make; Owing to impeller is made all-in-one-piece impeller, and serves as interior magnet steel seat, eliminated the fit up gap of impeller and impeller shaft, make circular runout reduce greatly, power loss reduces, and accuracy of manufacturing significantly improves; Because enclosed bearing support of single face and pump case form full-closed structure, liquid that can not leaks into motor side from pump chamber through bearing, power factor improves, and when running up, form liquid friction between impeller shaft and bearing, reduce mechanical wear greatly, make impeller be in good operating mode, life-span and significantly improve, bearing capacity strengthens greatly, can transmit more high-power.Because this pump magnetic force coupled mode is the axial plane delivery type, make the very simple compactness of whole magnetic drive pump structure.

Be illustrated below in conjunction with drawings and Examples.

Fig. 1 is the utility model overall structure schematic representation.

Fig. 2 is the utility model bearing block structure cross-sectional schematic.

Fig. 3 is the utility model bearing block structure front view.

Fig. 4 is the utility model blade wheel structure cross-sectional schematic.

Fig. 5 is the utility model blade wheel structure front view.

Sequence number 1 is a bearing support, and 2 is bearing, and 3 is pump case, and 4 is impeller, and 5 is magnetic shoe, and 6 is magnetic shoe, and 7 is the outer steel seat, and 8 is motor shaft, and 9 is motor, and 10 is hitch, and 11 is base.

As shown in Figure 1: the magnetic force coupling device by outer magnetic turn (comprising outer steel seat 7 and magnetic shoe 6), interior magnetic is turned (comprise in magnet steel seat be integrated type impeller 4 and magnetic shoe 5), bearing support 1, hitch 10 constitutes, hitch links up pump case 3 and motor 9.Bearing 2 places in the bearing hole, and the outer steel seat links by key and motor 8, and pump is placed on the base 11.Magnetic shoe 5 blocks of sticking embeddings were distributed on the tool back plane garden week of impeller, magnetic shoe 6 same blocks of sticking embeddings were distributed on the Transverse plane garden week of outer steel seat, the inside and outside magnetic surface that sticking embedding magnetic shoe of turning all forms a disk respectively, two planes are parallel to each other, the bearing support that forms full-closed structure with pump case is isolated with them, when magnetic is turned outside the driven by motor, because the same sex is repelled each other between magnetic shoe 6 and the magnetic shoe 5, the effect that there is a natural attraction between the sexes, inside and outside magnetic is turned and is formed the coupled mode of magnetic force moment of torsion plane delivery type, and interior magnetic is turned generation run-in synchronism fed sheet of a media.

As Fig. 2, shown in Figure 3: bearing support is that the center is the disk of a shrinkage pool, and this shrinkage pool is the bearing hole that matches with bearing, because bearing hole is that single face is closed, can not leak, and easily forms liquid friction.

As Fig. 4, shown in Figure 5: impeller is that impeller and impeller shaft are made unitary whole formula impeller, its back side is a plane, and a ring convex is arranged on this plane, makes bonding magnetic shoe stable, convenient, such impeller has been eliminated the fit up gap, makes circular runout reduce greatly.
