Hydraulic cylinders are widely utilized across numerous industries, but when one fails, the consequences can be severe, halting operations and causing significant disruptions. Many users report issues where hydraulic cylinders fail to function properly. To address this efficiently, it's essential to identify the root cause of the problem.
Most often, the issue arises with newly installed hydraulic cylinders. Initially, external factors should be examined, such as whether the mechanism connected to the cylinder is excessively forceful or obstructed. Additionally, verify that the hydraulic fluid pressure meets the required specifications.
If no external issues are found, the focus shifts to internal components. For instance, ensure that hydraulic fluid is flowing into the cylinder correctly. Also, inspect the cylinder’s internal components, including whether the moving parts are overly tight or if the cylinder was poorly designed or manufactured.
Further investigation involves examining the oil lines and circuits, such as checking for blockages in hose connections or assessing the condition of the overflow valve. Dirt accumulation can lead to leaks due to inadequate sealing between the cone valve and its seat. Cleaning the valve promptly can prevent such issues.
Sometimes, improper design or manufacturing leads to a cylinder failing to operate. This could happen if insufficient hydraulic pressure is generated upon the piston’s return stroke or if the operating area is too small at startup. Similarly, excessive lateral loading, weak structural support, or crushing of the cylinder can also result in similar problems.
When installing a hydraulic cylinder, alignment is critical. The cylinder’s axial position should align with the direction of motion, and the load applied should ideally pass through the cylinder’s axis to avoid eccentric loading, which can lead to seal damage, leaks, and sticking pistons. Horizontal installation is generally discouraged since the cylinder’s weight can cause deflection, leading to uneven loading and potential damage.
