Problems solved by technology

[0004] In the above-mentioned related technologies, the inventor believes that: the flameproof enclosure needs an airtight design to isolate the ignition source, and the heat dissipation through the heat dissipation holes on the heat dissipation cover will easily cause the internal heat to be discharged in time, and the three-phase asynchronous motor will easily be damaged under long-term use. Reduced work efficiency

Abstract

The invention relates to a flame-proof three-phase asynchronous motor, and relates to the technical field of three-phase asynchronous motors, the flame-proof three-phase asynchronous motor comprises a body, an inner shell fixedly connected to the body in a sealing manner, and an outer shell covering the inner shell, a cooling cavity is formed between the inner shell and the outer shell, a cooling pipe is arranged in the cooling cavity in a bending manner, and one end of the outer shell is provided with a rear end cover; and a cooling device for conveying cooling liquid into the cooling pipe is arranged in the rear end cover. According to the invention, the cooling pipe is arranged, and the cooling device is used for conveying the cooling liquid into the cooling cavity through the cooling pipe, so that the inner shell and the outer shell are cooled, the cooling effect is improved while the cooling area is increased, the heat dissipation efficiency of the three-phase asynchronous motor is improved, and the advantage of improving the working efficiency of the flame-proof heat dissipation motor is achieved.

Description

technical field [0001] The application relates to the technical field of three-phase asynchronous motors, in particular to a flameproof three-phase asynchronous motor. Background technique [0002] At present, the three-phase asynchronous motor is a kind of induction motor. It is a type of motor that is powered by a 380V three-phase AC power supply (phase difference 120 degrees) at the same time. Usually, in order to improve safety, a three-phase asynchronous motor with an explosion-proof shell is used. It can not only withstand the internal explosion, but also prevent the explosive products from passing through the flameproof gap. [0003] Related technologies such as a high-efficiency flameproof three-phase asynchronous motor disclosed by the publication number CN107394942A include a base, a reinforcing rib, a flameproof casing, a front cover, a motor shaft, a bearing, a shaft sleeve, a rotor, a junction box, and a wiring harness assembly , stator, rear end cover, heat di...
