Sand and dust abrasion test device and test method for train motor insulation structure

Abstract

A sand and dust abrasion test device and a test method for a train motor insulation structure are characterized in that the device at least comprises four parts of a working box, a dust removing system, a sand spraying pressurization system and a control system, wherein the dust removing system is a circulating system, and comprises a sand and dust collecting device, a sand and dust separation device and a dust removing device; the sand and dust collecting device is mounted below the working box. Sand and dust drop in a sand and dust collecting conical hopper after sand spraying, are sucked in a pipe through a dust suction system, and then are sent in the sand and dust separation device for sand and dust separation; dust, separated from the sand and dust separation device, is sent in the dust removing device by a pipe, and is treated by the dust removing device; and sand particles, separated from the sand and dust separation device, pass through the sand spraying pressurization system, and are conveyed to a spray gun by a pipe for secondary spraying to form recycling of sprayed sand, and the spray gun is mounted in the working box.

Description

technical field [0001] The invention relates to a test device and a test method for a motor product, in particular to a sand and dust abrasion test device and a test method for the insulation structure of a train motor, which are mainly used for the sand and dust abrasion test of the insulation structure of a train motor. Background technique [0002] During the operation of the train motor, due to the action of high-speed wind, a lot of sand and dust will enter the internal system of the motor, and the high speed will be obtained under the rotation of the motor rotor, which will cause impact on the insulation structure, making the life of the insulation structure shortened, the reliability is reduced, and the reliability of the motor operation is affected. Therefore, the general train motor will be subjected to the sand and dust abrasion resistance test of the insulation structure when it leaves the factory. [0003] At present, most domestic sand and dust abrasion tests u...

AI Technical Summary

Problems solved by technology

[0008] The technical problem to be solved by the present invention is that most of the sand and dust abrasion test devices for insulating structures in the prior art are provided with sand and dust impact conditions by a sandblasting machine, and the sandblasting machine is a single structure, which cannot realize simultaneous adjustment of multiple variables Therefore, the results obtained from the test cannot comprehensively reflect the lack of sand and dust abrasion resistance of the insulation structure of the train during operation. A sand and dust abrasion test method and device for the insulation structure of the train motor that can change various variables of sand blasting are proposed
