How to remove the dirt of the conductive slip ring product to ensure smooth operation

About how to remove the dirt generated in the operation process of the product, today xiaobian will share with you: when the motor is cleaned and checked, open the observation window cover plate and the dust discharge hole cover, and the collector ring room should be cleaned up. If there is dust or oil on the surface of the collector ring, a gasoline cloth can be used to wipe the dust and oil, after gasoline volatilization is allowed to drive. For the motor, the size of the brush spark should be observed during operation, and the wear of the brush and collector ring should be checked.

When the surface of the collector ring is worn or blackened by sparks, the slight fine sand cloth can be carefully polished and the abrasive shall be cleaned; in serious cases (such as grooves), the surface of the collector ring is required so that the roughness reaches 1.6 and the radial beating is less than 0.04 ㎜. The distance between the bottom surface of the brush grip and the surface of the collector ring should be kept about 3 ㎜.

When the brush is worn and Xinxin cannot maintain the normal position and pressure, or the brush is worn to 1 / 3 of the original height, the brush block should be replaced according to the requirements of the manual. After the replacement, the new brush and the contact surface of the brush and the collector ring should be processed into the corresponding arc to ensure the good contact between the brush and the collector ring (the contact surface is not less than 75% of the total area). During processing, the fine sand cloth is fixed on the surface of the collector ring, and the electric brush is ground into the required arc on the sand cloth by simulating the working condition.
