How To Reduce Damage To Hydraulic Cylinders
2023-10-30
It's evident that the hydraulic cylinder plays a critical role in the functioning of hydraulic presses, and proper design, manufacturing, and use are essential to ensure their longevity. Some key points regarding the factors affecting the working life of hydraulic cylinders are as follows:
1.Cylinder Wall: Cracks often develop on the inner wall and gradually propagate outward, typically in longitudinal or angled patterns. Fatigue damage due to repeated high working loads is common.
2.Flange Part: Transition arcs connecting the flange to the cylinder wall are prone to cracks that expand outward, potentially leading to partial or complete flange detachment.
3.Cylinder Bottom: Cracks may initiate on the inner surface of the transition arc at the bottom of the cylinder and expand outward, possibly resulting in complete fracture.
4.Cavitation: Honeycomb pitting caused by cavitation can damage hydraulic cylinders, particularly on the inner wall of the entry hole.
5.Design Considerations: Unreasonable structural sizing, such as inadequate flange height or excessive flange outer diameter, can impose excessive loads and contribute to damage.
Considering these factors, it is crucial to carefully analyze the specific situation and address any design, manufacturing, or usage issues to enhance the working life of hydraulic cylinders in hydraulic press applications.
