Hydraulic piston rod discoloration and solution
Dec 10, 2018

During frequent reciprocating motion, the cylinder is likely to be affected by oil quality and external factors, which may cause discoloration of the surface of individual hydraulic piston rods. Because the hydraulic oil contains more complex additives, the additive will crystallize and adhere to the surface of the piston rod under the specific temperature and high pressure of the hydraulic oil. Under the action of the hydraulic cylinder oil seal shear force, the piston rod discoloration is formed. phenomenon.


In addition, special attention should be paid to the use of hydraulic oil. Hydraulic oils of different grades should not be mixed as much as possible. Otherwise, the quality of the oil will be degraded, and in severe cases, the oil will deteriorate. The hydraulic oil contains a variety of additives with special effects. When oils with different system additives are mixed, it will affect its performance and even deteriorate the additives. In this case, the hydraulic piston rod may also be colored.


In this case, it is necessary to strengthen the maintenance and replace the hydraulic oil regularly. And choose the appropriate hydraulic oil according to the temperature of the working environment. It is necessary to regularly clean the water and sediment in the dirt tank of the hydraulic oil tank, and periodically change the hydraulic oil filter to reduce the coloration of the hydraulic piston rod.www.xhychromerod.com
