Injection molding machines are prone to some faults in the work - hydraulic system
July 25, 2022
Oil temperature is too high Oil temperature abnormal rise may be caused by abnormal cooling system or high pressure of hydraulic components when working.
1. The cooling system is not normal. 1) The cooling system is insufficiently supplied. If the water raft is not fully opened, the water pressure is insufficient or the pump flow does not meet the requirements.
2) Blockage of pipes, such as filters, cooling towers or water pipes.
3) The cooling water temperature is too high, such as the cooling tower cooling capacity is insufficient, or the damage or the temperature is too high.
2. The hydraulic system generates high heat. 1) The oil pump is damaged, and the internal parts wear high heat when rotating at high speed.
2) The pressure regulation is not proper, and the hydraulic system is in a high pressure state for a long time and is overheated.
3) Internal leakage of the hydraulic components, such as damage to the directional valve or damage to the seal ring, causes heat to be generated when the high pressure oil flows through the small space.
(2) Noise generates abnormal noise, indicating that parts are damaged or improperly adjusted. The cause should be repaired according to the location of the noise.
