Maintenance method of hydraulic cylinder:
1. The cylinder wall of the hydraulic cylinder. Generally, cracks appear on the inner wall and gradually develop outward. The lines develop outward, and the cracks are mostly distributed longitudinally, or form a 40-degree angle with the generatrix of the cylinder wall of the hydraulic cylinder.
2. The flange part of the hydraulic cylinder. First, lines appear on the outer surface of the cylinder flange at the transition arc, and gradually expand to the circumferential direction and to the inner wall, or the crack extends to the nail hole, causing the flange to partially fall off. In some serious cases, the flange may be adjusted along the transition arc. The loop cracked and fell off.
3. The bottom of the hydraulic cylinder. First, a circumferential crack began to appear on the inner surface of the transition arc at the bottom of the hydraulic cylinder, and gradually expanded to the outer wall, and even cracked.
4. Cavitation. The hydraulic cylinder is also damaged due to honeycomb pitting caused by cavitation, and it is easy to cause cavitation on the inner wall of the entry hole!
5. Design reasons. The structural size of the hydraulic oil cylinder is unreasonable. For example, the flange height is too small or the flange outer diameter is too large, which will damage the integrated should be too high.
The above is about the repair method of hydraulic cylinder, I hope it can be helpful to you!
