What to do if the hydraulic system temperature is too high, causing the hot press to shut down
Excessive temperature in the hydraulic system is a common malfunction during the operation of hot press machines, which may cause equipment shutdown and affect production efficiency. If not dealt with in a timely manner, it can accelerate oil aging, seal damage, and even damage core components such as hydraulic pumps. The following are the response steps:
Immediate shutdown inspection: When an abnormal increase in temperature is detected, the equipment should be stopped first to prevent the fault from escalating. Check if the hydraulic oil level is normal, and if it is insufficient, promptly replenish the same type of oil.
Troubleshooting the cooling system: Check if the cooler is working properly. If the fan or circulating water pump is faulty, it needs to be cleaned or repaired. At the same time, ensure that the surface of the radiator is clean and free from debris blockage.
Check the status of hydraulic oil: Oil contamination or deterioration can exacerbate system heating, and regular sampling and testing should be conducted. If the oil turns black or has an odor, replace it with new oil and clean the oil tank.
Assess system pressure and leakage: Excessive system pressure or internal leakage can increase energy loss and generate heat, requiring adjustment of relief valve pressure or maintenance of hydraulic cylinders, valve blocks, and other components.
Observing environmental factors: Ventilation should be strengthened in high-temperature environments, and auxiliary cooling devices should be added if necessary.
If the above measures are ineffective, it is recommended to contact professional maintenance personnel for further diagnosis to avoid blind operation. In daily maintenance, the hydraulic system should be regularly maintained, temperature changes should be recorded, and preventive measures should be taken.
Through the above methods, the problem of hydraulic system overheating can be effectively solved, ensuring the stable operation of the hot press machine.
