What are the reasons and troubleshooting methods for the temperature deviation of the hydraulic oil of the film blowing machine?

Blowing MachineWhat are the reasons for the deviation of hydraulic oil temperature and how to eliminate it?

① If the cooling water flow is small, check whether there is a partial blockage of foreign matter in the maintenance pipeline. After removing the foreign matter, increase the cooling water flow.

②The parts in the oil pump are severely worn and the oil delivery efficiency is low, which causes the pump body to heat up. The oil pump should be inspected and repaired.

③ The oil pressure of the hydraulic circulating oil working system is adjusted too high and should be lowered appropriately. ④ The pressure relief of the oil return line in the hydraulic transmission system is not sufficient, and the pressure of the return oil is too high, so the pressure relief should be adjusted.

⑤The pipeline caliber in the hydraulic system is unreasonable, and the local pipeline caliber is not matched. The hydraulic oil flow resistance is large, causing the hydraulic oil to heat up, and there may be foreign matter in the local pipeline. The pipeline should be cleaned.
