What is the reason of high working temperature of hydraulic oil of injection molding machine and its elimination method?
The flow of cooling water used to reduce the temperature of hydraulic oil is small.Check whether the cooling water pipeline is blocked, and increase the cooling water flow after troubleshooting.
Circulating oil pump has serious wear and low work efficiency, which makes the pump body heat up, and the hydraulic oil temperature is also high.Oil pumps should be serviced.
The oil pressure in the hydraulic drive system is too high.The oil pressure should be reduced appropriately.
If the oil return pressure is insufficient, it shall be appropriately adjusted to eliminate the high oil return pressure.
Improper sizing of tubing and valves in the hydraulic system leads to high oil flow resistance and high oil temperature rise.It is also possible that there is foreign matter blocking in the pipeline.
