Embodiment Construction

[0034] After the applicant's research and analysis, the reason for this problem (the existing motor cannot work for a long time) is that the current wet and dry motor is only marked with With 90% capacity cooling oil, the heat generated by the motor operation is quickly brought to the casing through the cooling oil, and the heat is dissipated by the cooling ribs. According to the experiment, the motor can run continuously and normally for 1 hour in the air, but it has not yet reached the required optimal time. However, the present invention increases the water circulation chamber without changing the oil cooling chamber, and through the design of the outer water inlet cooling The inner water outlet cooling channel and the inner water outlet cooling channel are used for water cooling of the oil-water cooling motor, and several groups of flushing pipes with the same inclination direction are designed on the inner water outlet cooling channel, and a flow limiting valve is designed...

Abstract

The invention discloses a dry and wet dual-purpose oil-water cooling motor, which comprises a motor shell, a motor rotor inserted into the motor shell, and a motor stator fixedly mounted in the motorshell and arranged at the periphery of the motor rotor, and the motor shell comprises a water circulation chamber and an oil cooling chamber arranged on the inner side of the water circulation chamber. According to the invention, the water circulation chamber is added under the condition that the oil cooling chamber is not changed; an outer side water inlet cooling channel and an inner side wateroutlet cooling channel are designed to perform water cooling work on the oil-water cooling motor; a plurality of groups of washing pipes with the same inclination direction are designed on the inner side water outlet cooling channel; and a flow-limiting valve is designed on the flushing pipe, and water flow passing through the flow-limiting swirling channel is accelerated through the flow-limitingswirling channel in the flow-limiting valve, so that water flow in the inner side water outlet cooling channel is stirred more violently, and sludge adsorbed in the motor shell is flushed.

Description

technical field [0001] The invention relates to a wet-dry dual-purpose oil-water cooling motor and a cooling method thereof, and relates to the H02P field of control or regulation of motors, generators or electromechanical converters, especially to the field of H02P29 / 60 control or detection of motor or driver temperature. Background technique [0002] The motor is represented by the letter M (the old standard is D) in the circuit. Its main function is to generate driving torque as a power source for electrical appliances or various machines. The generator is represented by the letter G in the circuit. Its main function The function is to convert mechanical energy into electrical energy. [0003] At present, the wet and dry dual-purpose motor is only filled with 90% cooling oil in the casing cavity of the stator, rotor, upper and lower bearings, and the mechanical seal chamber. Let the heat out. After experiments, the motor can continue to operate normally for 1 hour in th...
