Abstract

The invention discloses a motor shell with a ring runner coiled from a metal pipe. The motor shell comprises a motor shell body; a water outlet and a water inlet are formed in the motor shell body; the runner which is formed by coiling the metal pipe is arranged in the motor shell body; the runner is provided with a water inlet end and a water outlet end; the water inlet end of the runner is communicated with the water inlet; the water outlet end of the runner is communicated with the water outlet. According to the motor shell with the ring runner coiled from the metal pipe, the structure is simple, the design is ingenious, the layout is reasonable, the inner sleeve and the outer sleeve of the shell do not need to be processed respectively, welding does not need to be carried out, the processing and welding time is saved, the waste of materials caused by cutting scrap processing is reduced, and the work efficiency of a single product is greatly improved. Meanwhile, welding does not need to be carried out, so that the reliability of the product is improved, and the structure is attractive, firm and reliable; in addition, the manufacturing process is simple, and the manufacturing cost is low.

Description

technical field [0001] The invention relates to the field of motors, in particular to a motor shell with an annular flow channel wound by metal pipes and a production process thereof. Background technique [0002] As we all know, a common motor casing with an annular flow channel is usually composed of a casing inner sleeve and a casing outer casing. Generally, the annular flow channel is processed on the outer diameter of the inner casing of the casing, and then the inner casing and the outer casing of the casing are welded to form a whole motor casing with an annular flow path; this results in time-consuming processing, waste of materials, and simultaneous welding It is easy to have quality problems and cause liquid leakage. Contents of the invention [0003] The purpose of the present invention is to overcome the disadvantages of the above-mentioned prior art and provide a simple structure, firm and reliable, simple and practical process of the motor housing with a cir...
