Factors affecting service life hydraulic cylinder

Factors Affecting The Working Life Of Hydraulic Cylinders


Cylinder wall cracks: Cracks on the inner wall of the cylinder can develop outward and are often distributed longitudinally or at an angle of approximately 40 degrees with the cylinder wall busbar. These cracks may be caused by various factors such as stress, fatigue, or material defects. Over time, if left unaddressed, these cracks can worsen and potentially lead to cylinder failure.
Flange cracks: Cracks can appear on the flange part of the cylinder. Initially, row lines may appear on the outer surface of the transition arc of the flange, which gradually expand in the circumferential direction and towards the inner wall. In some cases, the cracks may reach the nail holes, leading to partial flange detachment. In severe instances, the cracks can form a circular pattern along the transition arc, causing complete flange failure.
Cylinder bottom cracks: Cracks can develop at the bottom of the cylinder, starting with circumferential cracks on the inner surface of the transition arc and gradually expanding towards the outer wall. In some cases, the cracks may propagate through the entire wall thickness.
Cavitation damage: Cavitation refers to the formation and collapse of vapor bubbles in a hydraulic system due to rapid pressure changes. It can cause honeycomb-like pitting on the inner wall of the entry hole of the hydraulic cylinder. Cavitation damage is often a result of improper fluid flow, high fluid velocities, or insufficient fluid pressure. It can weaken the cylinder wall and potentially lead to failure.
Design-related issues: Some cylinder failures can be attributed to design flaws. For example, if the flange height is too small or the flange's outer diameter is too large compared to the integrated load, it can result in excessive stress concentration and damage. Proper consideration of structural size and load requirements is crucial during the design phase to ensure the cylinder's durability and performance.
