Water-cooled motor shell detection equipment

Abstract

The invention discloses water-cooled motor shell detection equipment. The equipment comprises a detection frame and a control box; a first sealing pad is arranged at the bottom of the detection frame;a fixed device is arranged at the top of the detection frame; a water pipe is arranged on the inner wall of the detection frame; a plurality of water injection nozzles are formed in the water pipe; abarometric sensor is arranged on the first sealing pad and is connected with the control box through a lead; the fixed device comprises a lower platen; a pressure relief device is arranged on the lower platen; a gas pipe is arranged at the bottom of the detection frame and is penetrated in the first sealing pad; and a sealing device is arranged at the gas outlet of the gas pipe. Through the pressure relief device, the shells of tested motors are protected so that the safety of the equipment is increased; and the sealing device is matched with sealing cavities in the shells of the motors, so that the gas pipe is stably fixed to transport gas into the sealing cavities, thereby enhancing the motor shell detection effect of the equipment.

Description

technical field [0001] The invention belongs to the technical field of leak detection equipment for sealing parts, and in particular relates to a water-cooled motor casing detection equipment. Background technique [0002] The basic principle of the water-cooled motor is to use circulating water to take away the heat of the heating part, so that the heating part can be maintained at a normal allowable temperature. Water-cooled motors usually have two forms: shell water cooling and wire water cooling. The casing of the water-cooled motor is provided with a sealed cavity, and the cavity is provided with a water inlet and a drain hole. When in use, the device with circulating water is connected to the water inlet and drain hole, and the cooling circulating water flows into the casing through the water inlet hole. In the cavity, the cooling circulating water exchanges heat with the casing when passing through the casing, so as to achieve the effect of cooling the motor. The air...

Problems solved by technology

The airtightness of the sealed cavity determines the reliability of the motor, so the water-cooled motor needs to pass the airtightness test when it leaves the factory. At present, the method of ventilating the sealed cavity is usually used to check whether the sealed cavity is leaking. Gas phenomenon, but the air pressure in the sealed cavity continues to increase, which can easily exceed the bearing limit of the sealed cavity and cause damage to the motor casing, and the gas delivery pipe cannot be fixed in a better position for gas delivery in the sealed cavity
