How To Maintain Hydraulic Cylinder

Do a good job in cleaning, want to do a good job on the maintenance of the hydraulic cylinder, then it must do a good job of cleaning. This is a very important aspect, the hydraulic cylinder in the long-term use process will produce a lot of dust and stains, if not cleaned up in time, it will affect the normal use of the product, so we must do a good job in cleaning the equipment after using it every day, which is also a good maintenance method for this equipment.

Firstly, the hydraulic oil should be changed regularly and the filter screen of the system should be cleaned to ensure the cleanliness and prolong the service life.
Second, the oil cylinder in each use, to carry out full extension and contraction of the test run for 5 strokes, and then run with load. Why? In this way, the air in the system can be exhausted, and the systems can be preheated. The existence of air or water in the system can effectively avoid the phenomenon of gas explosion (or burning) in the cylinder block, which will damage the seal and cause internal leakage of the oil cylinder.
Third, the system temperature should be well controlled. If the oil temperature is too high, the service life of the seal will be reduced. If the oil temperature is too high for a long time, the seal will be permanently deformed or even completely invalid.
Fourth, protect the outer surface of the piston rod to prevent the damage to the seal by bumping and scratching. Clean the dust ring of the dynamic seal of the oil cylinder and the sediment on the exposed piston rod, so as to prevent the dirt on the surface of the piston rod from entering the oil cylinder and damaging the piston, cylinder or seal.
Fifthly, check the thread, bolt and other connecting parts frequently, and fasten them immediately if they are loose.
Sixth, often lubricate the connection parts to prevent corrosion or abnormal wear in oil-free state.
