Hydraulic Cylinder Common Faults And Solutions?

First, the cylinder action is poor. It may be due to impurities mixed in the hydraulic oil, blocking the reversing valve and other components, resulting in poor flow of hydraulic oil, the cylinder can not act normally. The solution is to replace the clean hydraulic oil in time, and clean the hydraulic system, check whether the filter is clogged, and replace it if necessary. At the same time, if the internal parts of the hydraulic cylinder assembly error, such as piston and piston rod installation is not centered, will also make the cylinder action is blocked, this time you need to re-assemble the parts correctly to ensure that the components are installed in place and with a good .

Second, the leakage problem. External leakage is usually due to aging, damage to seals, or cylinder barrel, piston rod surface scratches caused. To deal with, we should carefully check the seals, if found aging, broken, need to replace the appropriate seals in a timely manner; for the cylinder and piston rod surface of the minor scratches, can be polished and repaired, and in serious cases need to be replaced with the appropriate components. Internal leakage is mainly due to the gap between the piston and cylinder barrel is too large, or the seal on the piston failure, this case to measure the gap between the piston and the cylinder barrel, if the excess need to replace the piston or cylinder barrel, and replace the seal.
