The Importance Of Cylinder Seals in Hydraulic Cylinders
May 27, 2022
Hydraulic transmission uses hydraulic pressure to transmit power. In the hydraulic cylinder and the used
hydraulic cylinder seal products, the function of the cylinder sealing device is to prevent the leakage of
the working sealing medium and the external impurities attached to the piston rod and enter the
hydraulic cylinder. The quality of the cylinder sealing device will directly affect the working performance
of the entire hydraulic system. If the sealing effect of the hydraulic cylinder is not good, it will cause
serious internal and external leakage failure, external leakage will lead to waste of working medium,
pollute the machine and the environment, and even cause mechanical operation failure and mechanical equipment accidents. Internal leakage will cause the volumetric efficiency of the hydraulic system to droprapidly, and the required working pressure will not be reached. In severe cases, it will directly fail to work.Therefore, cylinder seal products are very important in the hydraulic cylinder sealing system.
Cylinder seal products can be used to prevent the leakage of working sealing medium oil and the intrusion of external gas and dust into the interior of the hydraulic cylinder, causing damage to the
cylinder and piston rod. Of course, it is impossible to achieve the sealing effect of the hydraulic cylinder. Because the piston rod is reciprocating, a small amount of oil is always brought out. However, this leakage should be as small as possible. On the contrary, if the piston rod does not take out any oil during the reciprocating motion, so that the piston rod operates in a dry friction state, it will shorten the working performance and service life of the hydraulic cylinder. Cylinder seals and cylinder seals are an
indispensable part of hydraulic equipment. The reliability and service life of the cylinder seal products are an important criterion for judging whether the hydraulic system is good or bad.
