The Solution To The Failure Of The Operation Of The Buffer Hydraulic Cylinder
Low control pressure: If the control pressure of the hydraulic system is too low, it can be caused by factors such as excessive throttling resistance in the control pipeline, improper adjustment of the flow valve, unsuitable control pressure setting, or disturbances in the pressure source. To address this issue, the following steps can be taken:
a. Check the control pressure source and ensure that it is properly adjusted to the specified value for the system.
b. Inspect the control pipeline for any excessive throttling resistance. This may involve checking valves, fittings, or other components that could be causing pressure drops.
c. Verify that the flow valve is correctly adjusted to allow the desired flow rate and maintain the appropriate control pressure.
d. Examine the pressure source for any disturbances or fluctuations that may be affecting the control pressure. Troubleshoot and rectify any issues with the pressure source.
Air entering the hydraulic system: If air enters the hydraulic system, it is typically a result of system leaks. To address this problem, the following steps can be taken:
a. Check the liquid level in the hydraulic oil tank to ensure it is at the recommended level. If necessary, replenish the hydraulic oil to the appropriate level.
b. Inspect the seals and pipe joints on the oil suction side of the hydraulic pump for any leakage. Replace or repair any faulty seals or joints to eliminate leaks.
c. Examine the oil suction coarse filter and determine if it is excessively dirty or clogged. Clean or replace the coarse filter element as needed to ensure proper oil flow and prevent air from entering the system.
Slow initial movement of the hydraulic cylinder: In low-temperature conditions, hydraulic oil can have high viscosity and poor fluidity, resulting in slow initial movement of the hydraulic cylinder. To improve this situation, consider replacing the hydraulic oil with better viscosity-temperature performance. Choose an oil with properties that allow for smoother flow and operation even in low-temperature environments.
By addressing these potential causes, it is possible to resolve issues related to low control pressure, air entering the system, and slow initial movement of the hydraulic cylinder. Regular maintenance, including checks for leaks and appropriate selection of hydraulic oil, can help prevent or mitigate these problems.
