Our factory is a high quality China manufacturer & supplier of materials for hydraulic cylinders, which including hydraulic cylinder tube and chrome plated rod, chrome plated tubes. Here in this article you will learn the main factors that affect the function and use of hydraulic cylinders.
What are the frequently damaged parts of hydraulic cylinders?
The damaged part of the hydraulic cylinder is mostly the arc part connecting the flange and the wall of the hydraulic cylinder tube, followed by the arc part from the hydraulic cylinder tube wall to the bottom of the cylinder. A small amount of cracks occurred in the cylinder wall, some of which were damaged by severe cavitation. As far as use is concerned, it has generally been subjected to a high working load when it is damaged, and cracks gradually form and expand, which belongs to fatigue damage.
Main factors affect the durability of hydraulic cylinders
There are many factors affecting the durability of hydraulic cylinders, which should be analyzed according to specific conditions, but they are mainly summarized as follows:
1. Wall of the hydraulic cylinder tube
Cracks generally appear on the inner wall and gradually develop outward. The columns develop outward, and the cracks are mostly distributed longitudinally, or at an angle of 40 degrees to the generatrix of the cylindrical wall.
2. Cylinder flange part
The first is that there are lines on the outer surface of the cylinder flange over the arc, which gradually expand to the circumferential direction and the inner wall, or the crack extends to the nail hole, causing the flange to partially fall off. In severe cases, the entire flange cracks and falls off along the transition arc.
3. Hydraulic Cylinder bottom
First, ring-shaped cracks began to appear on the inner surface of the transition arc at the bottom of the cylinder, and gradually expanded to the outer wall and cracked.
4. Cavitation
The hydraulic cylinder also has honeycomb pits that enter the inner wall of the hole due to cavitation, which is prone to cavitation! At the same time, the impact on the seal is not small. Generally, it will accelerate its aging and need to be replaced in time. At the same time, it will also affect the cost and work efficiency. The most important thing is that it will accelerate the deterioration of the hydraulic oil, causing some parts to block, some pipelines to rupture, and cause great damage to the hydraulic pump station.
