Explanation of characteristics of hydraulic slip ring

We all know that seals play a very important role in the operation of hydraulic slip rings . If the sealing ring is damaged , The sealing property of the slip ring will be greatly reduced , It will not only aggravate the wear of the main shaft , There will also be leakage outside the slip ring , Thus shortening the service life , Affect the normal operation of the machine . therefore , It is important to find out the cause of the failure of the hydraulic slip ring seal .

At present , The causes of hydraulic slip ring seal failure are mainly divided into normal wear and abnormal wear . Normal failure refers to the wear of the hydraulic slip ring when the service life of the seal is close to or reaches the design life , Generally, this mode takes a long time . The seal failure caused in a short time belongs to abnormal wear . When the hydraulic slip ring is normally worn, the seal fails , Users need to replace . For abnormal wear , We need to analyze the reasons , Develop countermeasures .

According to the analysis of professionals , The main reasons for seal failure of mofuron technology hydraulic slip ring due to abnormal wear are as follows ： First, the surface roughness of the slip ring seal groove does not meet the standard . Due to unqualified processing , Make its surface roughness higher , Cause abnormal wear on the rotating contact surface between the sealing jacket and the hydraulic slip ring , Cause hydraulic oil leakage inside the equipment . Second, the uneven wear of the slip ring bearing causes the body eccentricity . The main bearing of the hydraulic slip ring is worn unevenly , Cause eccentricity , It causes uneven bite clearance between the rotating part and the stationary part of the slip ring , Make the seal unable to tighten the slip ring surface , Cause hydraulic oil leakage . Third, foreign matters enter the hydraulic slip ring , During operation, solid particles repeatedly scrape and rub the sliding ring, the moving and stationary ring, or embed into the seal , Cause the hydraulic slip ring seal to scratch or accelerate its severe wear and failure . Fourth, corrosion and wear . Although the crude oil medium in the ring cavity of the hydraulic slip ring should not contain corrosive substances , The oil product changes due to the change of oil production mode or other reasons , Cause the oil to contain corrosive substances . Under the action of acid substances , The sealing components of the hydraulic slip ring are corroded , So it will fail , Cause hydraulic oil medium leakage .
