An abnormal rise in oil temperature may be caused by an abnormality in the cooling system or high heat generated by the hydraulic components during operation.
1, the cooling system is not normal
1) Insufficient supply of cooling system, such as insufficient water opening, insufficient water pressure or pump flow does not meet the needs.
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 produces high heat
1) The oil pump is damaged, and internal parts are worn at high speed to generate high heat.
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.
