Fault Judgment of Hydraulic Cylinder When Not Moving
Hydraulic cylinders are widely used in various hydraulic systems due to their features of fast response, large output, and adjustable speed. However, in actual operations, hydraulic cylinders will sometimes not move. This can cause serious losses to the production cycle and must be dealt with quickly. The following are the fault judgement processes for hydraulic cylinders when they are not moving:
1. Hydraulic cylinder components. Inspect whether the piston rod, cylinder head, cylinder rod, piston seal, lock nut and other components of the system are in normal working order.
2. Check the outlet pressure. Through a direct measurement of the pressure at the outlet of the hydraulic cylinder, adjust the pressure according to the needs of the system, and then test the operation of the hydraulic cylinder.
3. Check the oil quality. It can be judged by temperature measurement or microscopic oil analysis to check whether the oil is too volatile, deteriorated or oxidized.
4. Check out the pilot system. The pilot system can also be used to determine whether the hydraulic cylinder is running normally.
5. Check the spool. Determine if the spool has stuck or other problems by a careful inspection of the spool.
6. Check the pressure compensator. Check the pressure compensator settings to ensure that pressure is correctly set.
7. Check the hydraulic pipeline system. Check valves, joints, pipe connections, and other parts of the hydraulic system for blockages or leaks.
After the above steps are completed, the problem is identified and the solution is determined. The method and means used to repair the problem must be chosen according to the nature of the fault and the system requirements. In order to prevent similar problems in the future, regular maintenance should be carried out to ensure the normal operation of the system.
In conclusion, it is important to properly judge the fault of the hydraulic cylinder when it does not move. This can help prevent losses due to production delays and help keep the system running smoothly.
