Abnormal noises from hydraulic oil pipes may be caused by air inside the pipes, quality issues of the hydraulic oil, or wear on the inner walls of the pipes.
The following are some specific handling methods:
1. Exhaust air: If the abnormal noise is caused by air in the oil pipe, it can be resolved by exhausting air. Open the exhaust valve of the system to let the air in the oil pipe escape until the oil flows out.
2. Check the oil quality: Abnormal noises may be caused by contamination or deterioration of the hydraulic oil. Regularly check the quality of the hydraulic oil and replace it with a new oil if necessary.
3. Inspect the oil pipe: Check if the oil pipe is worn or damaged. If so, it should be replaced as soon as possible. At the same time, check whether the connection parts of the oil pipe are tight. If any are loose, they should be tightened in time.
4. Adjust the hydraulic system: If none of the above methods can solve the problem, it might be caused by excessive working pressure or too fast working speed of the hydraulic system. Adjust the working parameters of the hydraulic system appropriately to ensure its operation within the normal working range.
