Description
Technical Field
The utility model relates to the technical field of pumps, in particular to a pump with a circulating cooling structure.
Background
The existing pumping structure is free of a cooling system, and cooling is usually achieved through external cooling or environmental cooling. In the use of pumping, can produce high temperature because of the friction between axle sleeve, the axle core when impeller is operated, external cooling or environmental cooling are poor to the cooling effect of the inside high temperature that produces of pumping, lead to the inside heat that can gather of pumping operation in-process, can lead to interior magnetism rubber coating melting deformation when serious, and the conventional spare part of pumping also can receive high temperature to influence and produce deformation, damage and/or ageing etc. moreover, influence the normal work of pumping, seriously influence the life of pumping simultaneously.
Disclosure of Invention
Aiming at the defects of the prior art, the utility model provides the pump with the circulating cooling structure, so that the circulating cooling structure is formed in the pump structure, and the cooling efficiency of the pump is greatly improved.
The technical scheme adopted for solving the technical problems is as follows:
the pump with the circulating cooling structure comprises a shaft sleeve, an inner magnetic assembly and an impeller, wherein the shaft sleeve is arranged inside the inner magnetic assembly, the impeller is arranged at the top end of the inner magnetic assembly, a cutting surface is arranged on the outer edge of one side of the shaft sleeve, a square hole is formed in the upper portion of the inner magnetic assembly, and a space formed by the cutting surface inside the inner magnetic assembly is communicated with the square hole in series to form the circulating cooling structure.
Further, the cutting surface and the square hole are positioned at the same side, so that the space formed by the cutting surface after the shaft sleeve is arranged in the inner magnetic assembly can be communicated with the square hole on the inner magnetic assembly.
Further, the cutting surface is provided with an inclined stop surface from the lower part to the upper part, and the stop surface is opposite to the square hole.
Further, the impeller is arranged on one side of the front cover, which is close to the inner magnetic assembly.
The upper part and the top part are all in the direction which takes the central axis of the shaft sleeve as the center and is close to the front cover side; the lower parts are all far away from the front cover side.
Compared with the prior art, the utility model has the following beneficial effects:
according to the pump disclosed by the utility model, the cutting surface is arranged on the shaft sleeve, meanwhile, the square hole is correspondingly arranged on one side of the cutting surface on the inner magnetic assembly, so that the space formed by the cutting surface after the shaft sleeve is arranged in the inner magnetic assembly is communicated with the square hole in series, and a circulating cooling structure is formed.

Detailed Description
The technical scheme of the utility model is further described below with reference to specific embodiments.
As shown in fig. 1-4, the pump with the circulation cooling structure comprises a shaft sleeve 1, an inner magnetic assembly 2 and an impeller 3, wherein the shaft sleeve 1 is arranged inside the inner magnetic assembly 2, the impeller 3 is arranged at the top end of the inner magnetic assembly 2, a cutting surface 11 is arranged on the outer edge of one side of the shaft sleeve 1, a square hole 21 is formed in the upper portion of the inner magnetic assembly 2, and a space formed by the cutting surface 11 and the square hole 21 are communicated in series to form the circulation cooling structure 4 in the shaft sleeve 1.
Further, the cutting surface 11 and the square hole 21 are positioned on the same side, so that the space formed by the cutting surface 11 of the sleeve 1 arranged inside the inner magnetic assembly 2 can be communicated with the square hole 21 on the inner magnetic assembly 2.
Further, the cutting surface 11 is provided with an inclined stop surface 12 from the lower part to the upper part, and the stop surface 12 is arranged opposite to the square hole 21.
Further, the impeller 3 is arranged on one side of the front cover, which is close to the inner magnetic assembly 2.
The working principle of the utility model is as follows: the pump in the operation in-process, can form an outside centrifugal force to liquid when impeller 3 rotates, make the space pressure that is close to axle sleeve 1 increase, and then make square hole 21 department form certain suction, make the coolant liquid get into circulation cooling structure 4 from the bottom, flow out from square hole 21 at top again and form a circulation, and then realize the inside cooling of pump body, make the cooling of pump more rapid, high-efficient.
The upper part and the top part are the directions which take the central axis of the shaft sleeve 1 as the center and are close to the front cover side; the lower part and the bottom are both far away from the front cover side.
It should be understood that the foregoing description is only of the preferred embodiments of the present utility model, and is not intended to limit the utility model, but is intended to cover all modifications, equivalents, alternatives, and modifications falling within the spirit and principles of the utility model.
