Reasons for rapid wear of conductive slip rings

Depending on how the slip ring works , We can know that the slip ring belongs to sliding contact , 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 experiments , It is concluded that the lower the wear degree of the slip ring , The longer the service life . From a large amount of data, we can know , The wear resistance of slip rings made of different raw materials is different . Strength of raw materials for manufacturing slip rings 、 Friction coefficient and current density have a great influence on the wear of slip ring during operation .

When the slip ring contacts with other objects , The more pressure , The same friction force will be generated , The sliding ring is greatly worn . But the contact pressure on the slip ring is too small , When the slip ring contacts the contact surface, the resistance will increase instantaneously , In serious cases, sparks will appear , It will also cause the slip ring to wear , therefore , The wear rate of the slip ring is determined by the nature of the manufacturing material . Slip rings can only be produced if the production materials and processes of slip rings pass the standards , It can reduce the impact of wear during operation .

How to repair the worn slip ring of mofuron Technology ：

1、 Surface baking oil ： Bake oil on the worn journal surface with acetylene flame ;

2、 Repair keyway ： Welds in the support keyway , Site repair , Try to install with flat keys ;

3、 Surface treatment ： Grind the worn parts with a grinder , Punch the circumferential ring with the sample , Make the pitting points bulge evenly ;

4、 cleaning ： Clean the polished bearing chamber with absolute ethanol ;

5、 Blend SD7101H After the material , use Sore Industrial site repair process repair ;

6、 Assemble the slip ring stator in place , And lock the nut on site .
