Hydraulic presses are widely used in industrial production and are responsible for transferring energy to the machine's moving parts by compressing liquids. Although hydraulic presses can work for a long time without any problems, there may be cases of equipment failures that affect the production efficiency and equipment reliability. Here are some common faults and their solutions to deal with hydraulic presses:
High oil temperature
If the oil temperature of the hydraulic press is too high, it can cause a hydraulic system failure or even damage the machine. The causes of this problem may include mechanical parts wear, oil pump malfunctions, or oil circuit blockage. To address this issue, you can use high-quality hydraulic oil, thoroughly clean the oil circuit, frequently replace the filter, and adjust the operating parameters of the hydraulic system correctly.
Loud noise from the oil pump
If you hear a loud noise from the oil pump, the problem is likely to be caused by the air or bubbles in the hydraulic system and the deviation of the pump pressure. In this case, you can eliminate the air or bubbles in the oil circuit, replace the oil pump, or adjust the pressure adjustment valve.
Clicking sound from the relief valve
When the hydraulic press is running, the relief valve might make a clicking sound. This fault is usually caused by the excessive pressure in the hydraulic system or insufficient oil level in the crankcase. To solve this problem, you can try to clean the oil circuit, adjust or replace the relief valve, and ensure that the oil level in the tank is sufficient.
Hydraulic cylinder malfunction
If the hydraulic cylinder fails to function properly, the problem is typically due to the wear of the hydraulic sealing ring or loosening of the air cylinder. To fix this issue, you can either replace the hydraulic sealing ring or reconfigure the system.
In conclusion, although hydraulic presses are typically highly reliable equipment, it is essential to be aware of the possible problems that may occur and their corresponding resolve procedures. By taking appropriate measures, such as using high-quality hydraulic oil, frequently cleaning the oil circuit, replacing filters, paying attention to the pressure levels, and performing proper maintenance and timely repairs, you can reduce the likelihood of equipment failures and successfully enhance your production efficiency.
