In short, hydraulic cylinders are mechanical components that provide force in one direction through a stroke. These cylinders are widely used in various industrial applications. Due to many reasons, problems may occur in the long run. The following are caused by hydraulic cylinders. Several reasons for failure.
1. piston rod scratches:
Scratches on the piston rod are usually caused by oil contamination. If this happens to your cylinder, you should pay special attention to whether there are any further contamination, such as gland bearings. If not properly maintained, it may cause bearing damage.
2. seal leakage:
This is a common problem that usually causes hydraulic cylinders to fail, and seals often leak due to improper seal installation or seal groove corrosion.
3. oil barrel internal corrosion:
The water in the oil is the most common cause of corrosion inside the oil drum. At this point, the best way to reduce cylinder failure is to change the oil.
4. chemical attack
In many cases, the failure of the hydraulic cylinder may be caused by the contact of chemicals with the hydraulic cylinder sealing ring. This can be avoided by discussing the possibility of chemical attack with the hydraulic manufacturer so that you can have a good understanding of the bearing capacity of the cylinder seal.
5. bending piston rod:
This problem most often occurs when the hydraulic cylinder is overloaded, which may occur due to some kind of conflict or the use of a system that exceeds its agreed specifications.
6. oil contamination:
Oil contamination is the main problem associated with hydraulic cylinder failure. Contaminated liquid can severely damage the piston rod, sealing surface and/or cylinder bore. The best way to avoid hydraulic cylinder failure is to regularly check the oil for potential contamination.
