Problems solved by technology

[0004] During the mass production process of water-cooled motors, the sealing performance is uneven. After being put into use, there are often repairs and repairs. Some water-cooled motors even directly enter the water when they are used in a submerged state, resulting in short-circuit faults in the internal stator and rotor. It affects the later use experience and efficiency, and also increases the cost of production and maintenance

Abstract

A water cooling motor air leakage detection method disclosed by the present invention belongs to a leakage detection method of the sealing structural parts. By a machine sealing cavity leakage detection step, a motor cavity leakage detection step, a coolant gallery leakage detection step and a leakage detection test ending step, the air leakage detection of a water cooling motor is finished, thereby guaranteeing that before the water cooling motor is used, the sealing performances of the parts satisfy the usage demands, reducing the overhauling and reworking probability after the water coolingmotor is used, and reducing the maintenance cost.

Description

technical field [0001] The invention relates to a method for detecting leaks of sealed structural parts, in particular to a method for detecting air leakage of a water-cooled motor. Background technique [0002] At present, due to the high noise of the traditional air-cooled motor, the heat dissipation effect is easily affected by the environment and the use of time, and it cannot be used in a submerged state. Water-cooled motors are mostly used instead of air-cooled motors. The current structure of water-cooled motors is mostly to open water-cooling channels in the motor housing, and to fill the inside of the motor with water-cooling channels to meet the cooling effect. [0003] However, the existing water-cooled motors have the following defects: [0004] During the mass production process of water-cooled motors, the sealing performance is uneven. After being put into use, there are often repairs and repairs. Some water-cooled motors even directly enter the water when th...
