How To Solve The Noise Generated By The Hydraulic Cylinder During Work

Apologies for the confusion earlier. The steps you provided are correct. Here's a summary:
Step 1: Clean the Filter: Regularly clean the hydraulic cylinder's oil filter to remove dirt and impurities from the hydraulic oil. Accumulated pollutants can block the filter, impairing its ability to filter the oil properly. If the oil becomes contaminated, it can cause noise during equipment operation. Noise issues can be resolved by replacing the oil with fresh oil or removing any blockages from the filter.
Step 2: Fill up the Oil Level: Check the oil level in the hydraulic cylinder during use. If the oil suction position is too high and the oil level is insufficient, the oil suction pipe may be exposed, resulting in inadequate oil absorption and lubrication. This can lead to noise during frequent operation. To reduce noise, fill the hydraulic cylinder up to the recommended oil level and adjust the position of the oil suction to ensure proper lubrication.
Step 3: Adjust the Concentricity of Pump and Motor Coupling: If the driving shaft of the hydraulic cylinder and the motor coupling are not concentric, it can cause twisting and friction. Severe friction can generate significant noise. Adjusting the concentricity of the pump and motor coupling can eliminate the noise caused by this friction.
Step 4: Replace the Pump Shaft Oil Seal: If the oil seal skeleton of the hydraulic cylinder's shaft falls off, it can result in inadequate sealing of the pump body, leading to creaking noises. The noise may intensify with increased working force. To reduce the noise, replace the damaged or missing oil seal with a qualified one. This will restore proper sealing and resolve the noise issue.
