How to reduce the degree of damage to hydraulic cylinders?

Sep 27,2023

The damaged parts of hydraulic cylinders are mostly located in the curved area connecting the flange and the cylinder wall, followed by the curved area transitioning from the cylinder wall to the cylinder bottom. There are a few cracks on the cylinder wall, some of which are damaged due to severe cavitation. In terms of usage conditions, fatigue damage generally occurs when a higher number of operating loads are experienced during damage, and cracks gradually form and propagate. There are many factors that affect the service life of hydraulic cylinders, and analysis should be conducted based on specific situations. However, generally speaking, there are several aspects:

1. Cylinder wall. Cracks generally appear on the inner wall and gradually develop outward. Cracks are mostly distributed longitudinally or at a 40 degree angle to the cylinder wall busbar.

2 The flange part of the cylinder. Firstly, there are lines on the surface of the cylinder flange at the transition arc, which gradually extend towards the circumferential and inner walls. Perhaps the crack extends to the nail hole, causing the flange to partially detach, resulting in severe single cases, or the entire circle of the flange at the transition arc will crack and detach.
