Abstract
The utility model relates to an improved magnetic pump structure, which provides a magnetic pump with simple structure and long service life. The utility model comprises a pump body connected with an electric motor by a connector, and a bracket which is arranged on an electric motor shaft and is provided with a magnet. The utility model is characterized in that a cone seat at the left side of an impeller contacts the tip cone body at the top of a regulating bolt on the pump body; the impeller is connected with the cone seat on a shaft sleeve of the pump body by the tip cone body which is connected by a distance sleeve; a magnet corresponding to the magnet on the frame is arranged outside the distance sleeve; the surface of the impeller, the inner surface of the connector, the inner surface of the pump body, and the inner surface of the shaft sleeve are coated with polytetrafluoroethylene.
Description
Technical field:
The utility model is the improvement that belongs to the magnetic drive pump structure.
Background technique:
The impeller of present magnetic drive pump is fixed on the bearing of the pump housing usually, makes the pump structure more complicated, and brings very big inconvenience to installation and maintenance; In addition, with the easy to wear and corrosion in the contacted position of fluid, therefore, influenced the life-span of pump on the impeller and the pump housing.
The model utility content:
The utility model is exactly at the problems referred to above, and long magnetic drive pump of a kind of simple in structure, life-span is provided.
The utility model adopts following technological scheme: the utility model comprises the pump housing, the pump housing links to each other with motor by connecting body, have magnet on the support on the motor shaft, its structure outline is that the cone seat in impeller left side contacts with the top cone on the conciliation bolt top on the pump housing; Impeller links to each other with the cone seat on the axle sleeve on the pump housing by the top cone that separation sleeve links to each other, and separation sleeve is outside equipped with the corresponding magnet of the magnet on the support; Scribble teflon at impeller surface, connecting body internal surface, pump housing internal surface, axle sleeve internal surface.
The beneficial effects of the utility model:
Because impeller of the present utility model is separately fixed on the top cone in the cone seat on right side and left side, has just removed the bearing on the pump housing from; Not only make pump structure simple, and made things convenient for installation, maintenance;
In addition, scribble teflon, improved the working life of pump at impeller surface, connecting body internal surface, pump housing internal surface, axle sleeve internal surface.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Embodiment:
The utility model comprises the pump housing 18, and the pump housing 18 links to each other with motor 1 by connecting body 3, has magnet 8 on the support 4 on 12 in the motor, and the cone seat 13 in impeller 12 left sides contacts with the top cone 14 on conciliation bolt 15 tops on the pump housing 18; Impeller 12 links to each other with the cone seat on the axle sleeve on the pump housing 18 56 by the top cone 7 that separation sleeve 10 links to each other, and separation sleeve 10 is outside equipped with the 8 corresponding magnet 9 of the magnet on the support 4; On impeller 12 surfaces, connecting body 3 internal surfaces, the pump housing 18 internal surfaces, axle sleeve 5 internal surfaces scribble teflon.
Top cone 14, top cone 7 all can be made by carbofrax material; Cone seat 13, cone seat 6 all can be made by graphite material.
For preventing that reconciling bolt 15 enters dirt etc., can be outside equipped with Protective nut 16 at conciliation bolt 15.
Below in conjunction with a description of drawings course of action of the present utility model:
Motor 1 rotates, and the magnet 8 of the support 4 on 12 in the motor rotates, and the magnet 9 on the separation sleeve 10 of the pump housing 18 rotates under 8 effects of the magnet on the support 4 thereupon; Be that impeller 12 moves under the support of left side top cone 14, right side cone seat 6, liquid is sucked in the pump housing 18 by inlet 17, discharge outside the pump housing 18 by outlet 11 again.
