The role of the heat exchanger of the four-column hydraulic press

The working temperature of the oil in the hydraulic system of the four-column hydraulic press is generally kept in the range of 30 to 50 °C, the highest is not more than 60 °C, and the lowest is not lower than 15 °C. Excessive oil temperature will deteriorate the oil, accelerate its pollution, cause the orifice to be blocked, reduce the viscosity and lubricity of the oil, increase the leakage between the gaps, and shorten the working life of the hydraulic components. If the oil temperature is too low (such as in a cold area), it is difficult for the hydraulic pump to start to absorb oil.

In order to improve the working stability of the hydraulic system, the system should work at a suitable temperature and maintain thermal balance. Using a heat exchanger to control the oil temperature can not only ensure the normal operation of the tie wrap, but also reduce the thermal deformation of the main engine and improve the working accuracy of the main engine. If the hydraulic system cannot limit the oil temperature below the allowable value by relying on natural cooling, a cooler must be installed; on the contrary, if the ambient temperature is too low to enable the hydraulic pump to start normally, a heater must be installed.
