According to the working mode of the slip ring, it is known that the slip ring belongs to sliding contact, and the contact surface between the slip ring and other objects is the first to wear during the sliding process.The wear rate of slip ring plays a decisive role in its service life.After a lot of tests, it is concluded that the lower the wear degree of slip ring, the longer the service life.It can be known from a large number of data that the wear resistance of slip rings produced by different raw materials is different.The strength, friction coefficient and current density of the materials used to make the slip ring have great influence on the wear of the slip ring during operation.

 


When the slip ring is in contact with other objects, the greater the pressure, the same friction will be generated, resulting in much wear of the slip ring.However, if the contact pressure on the slip ring is too small, the resistance will increase instantly when the slip ring contacts the contact surface, and sparks will appear in serious cases, which will also cause slip ring wear.

 

Therefore, the wear rate of the slip ring is determined by the nature of the manufacturing material.Slip ring production materials and production process through the standard to produce slip ring, can reduce the impact of working wear.

 

 

 

How to repair slip ring wear:

1. Surface baking oil: use acetylene flame to bake oil on the surface of worn journal;

2. Repair the keyway: support the welding spot in the keyway, repair it on site, and install it with flat keys as far as possible;

3. Surface treatment: Grind the worn parts with a grinder and punch the circumferential ring with the sample to make the pitting points protrude uniformly;

4. Cleaning: Clean and polish the bearing room with anhydrous ethanol;

5. Blend SD7101H materials and use Sore on-site industrial repair process for repair;

6. Assemble the sliding ring stator in place and tighten the nut on site.
