How to extend the use time of hydraulic cylinders?

1. Keep the hydraulic oil clean. Dirt in the oil can damage the components of the system.

2. Maintain the hydraulic oil volume. If there is less oil, air will enter and the system will not operate normally.

3. Pay attention to whether the oil cylinder is leaking. Oil leakage indicates that the seal is broken, and it is not replaced in time, which not only consumes oil, but also reduces the output, and does not act in severe cases.

4. Familiar with the sound of system operation. Normal and faulty sounds are different. If you hear abnormal sounds, you will know that there is something wrong, and remove it in time to prevent minor faults from becoming major damages and causing major losses.

5. Pay attention to check whether the tight parts are loose. To maintain its effective tight failure state.

The use of hydraulic cylinders is very common and is widely cited in mechanical equipment. The O-ring is the most easily damaged cylinder. When the O-shaped sealing ring of the cylinder is worn, the gap between the rod cavity and the rodless cavity of the cylinder increases, which is equivalent to cutting off the oil return path of the cylinder rod cavity. In practice, due to the gap between the two chambers of the cylinder, the pressure oil in the cylinder chamber tends to flow from the high pressure area to the low pressure area. Once the flow occurs, the piston loses balance and moves to the rod chamber to find a new balance point. In this reciprocation, the piston will not stop until it is blocked by external force. The occurrence of the above phenomenon has a great impact on the operation of the hydraulic system. After replacing the "O"-shaped sealing ring of the cylinder piston, the unstable operation of the cylinder can be completely improved. At the same time, it can greatly extend the service life of the cylinder.
