What Are The Reasons For The Failure Of The Hydraulic Cylinder?
2023-10-30
1. Cavitation
Cavitation can cause failure of the hydraulic cylinder and cause great harm. It can not only turn the surface of the hydraulic cylinder black, but also burn the support ring and sealing ring. In addition, when the cavitation is serious, the oil cylinder There will also be some honeycomb holes on the inner wall and the surface of the piston or piston rod, which will cause the hydraulic cylinder to fail to work normally. Therefore, cavitation prevention should be done in normal use.
2. The oil quality is not good
When the hydraulic cylinder is used, a certain amount of hydraulic oil needs to be poured into it. If the quality of the hydraulic oil is not good, the performance against foam will be relatively poor. After a long time of use, it is very easy to produce foam and cause adverse effects on the hydraulic cylinder. . In addition, if the frequency of the hydraulic oil pressure changes too high and too fast, and the temperature of the oil is too hot, the hydraulic cylinder will be damaged to varying degrees.
3. Welding is not handled properly
Some parts of the hydraulic cylinder are connected together by welding process, especially the oil port seat and other parts, the weld seam itself does not have a high affinity, if it is not handled properly during welding, it is easy to leave gaps in the welding part , and the side legs of the oil port seat are elongated or the wall thickness at the corner is insufficient, resulting in damage to the oil port connection.
