1. The use of hydraulic oil recommended by the manufacturer of hydraulic press and tension machine, hydraulic oil with appropriate viscosity, if the hydraulic oil has high viscosity, especially in areas where the ambient temperature is relatively low, it will cause the increase of flow friction and the generation of overheating.
2, the hose should be reliably clamped and positioned, when the pump, hydraulic cylinder and other hydraulic components wear should be replaced in time. Because the worn components will cause an increase in leakage, the pump will be full flow output for too long, and the oil through the narrow leak gap will cause a large pressure drop, and the increase in the slow flow output time also increases the time of fluid friction, so the oil temperature will rise.
3, keep the oil system outside and inside clean, the system outside the pollutants play a role in isolating and obstructing the normal oil cooling, the system inside the pollutants will cause wear resulting in oil leakage, the occurrence of both cases will cause heat generation.
4, often check the liquid level of the oil tank, the oil level is too low will cause the system does not have enough oil to take away the heat.
5. Regularly replace the filter element of the steel hydraulic press to avoid filter clogging.
