Mini excavator hydraulic cylinder maintenance points

The maintenance points of various parts of mini excavator are different. Hydraulic cylinder is an important part of mini excavator. Improper maintenance often causes oil leakage, so attention should be paid to it. Next, let's talk about the maintenance points of mini excavator hydraulic cylinder. Let's take a look.

First, do a good job of piston rod protection, to prevent knock and scratch damage to the seal. It is necessary to often clean the dust ring parts of the cylinder dynamic seal and the exposed piston rod of the sediment, to prevent the dirt pasted on the surface of the piston rod that is not easy to clean into the cylinder, resulting in damage to the piston, cylinder or seal.

Two, pay attention to the tightness of each part of the connection. Pay attention to check the thread, bolt and other connection parts, find loose immediately tighten. Because these places loose will also cause the hydraulic cylinder oil leakage.

Three, regular replacement of pressure oil, timely cleaning of the system screen, to ensure the cleanliness of hydraulic oil, which is also a very important role in prolonging the service life of the hydraulic cylinder.

Four, corrosion and rust prevention.The joint should be lubricated frequently to prevent corrosion or abnormal wear without oil. Especially for some parts of the corrosion phenomenon, should be dealt with in time to avoid corrosion caused by hydraulic cylinder oil leakage.

The above introduced mini excavator hydraulic cylinder maintenance points, a simple understanding of!
