When the hydraulic system is working, the volume loss and mechanical loss of the hydraulic pump, hydraulic motor and hydraulic cylinder, the pressure loss of the hydraulic control device and pipeline, and the viscous friction of the working medium will cause energy loss. All the energy lost in the system is converted into heat energy, and most of it is absorbed by the hydraulic oil, which increases the temperature of the working medium of the hydraulic system. An increase in oil temperature will reduce the viscosity and lubricity of the oil and increase leakage. If the oil temperature is too high, it is easy to contaminate the oil system and precipitate bituminous substances. Once they enter the waving surface of the component and the intermittent cooperation, it will cause various failures, shorten the working life of the component, and directly affect the normality of the hydraulic system. jobs. In high-cold areas, because the working environment temperature is too low, it will cause difficulty in system startup and oil absorption, cavitations will occur, and normal operation of the system will also be affected.
The hydraulic system maintains thermal balance at a suitable working temperature, which is not only necessary for the hydraulic system, but also helps to improve the stability of the system, reduces the thermal deformation of the mechanical equipment, and improves the working accuracy. In order to control the oil temperature within the working range, a cooler can often be used for forced cooling, and a heater can be used for preheating.
The heat in the hydraulic system can generally be naturally dissipated through three basic methods: heat conduction, heat radiation, and heat convection. The heat will automatically reach thermal equilibrium at a certain temperature. If the heat balance temperature exceeds the maximum temperature allowed by the hydraulic system, or there are special requirements for temperature, a cooler should be installed for forced cooling, and vice versa. If the temperature is too low, the oil pump cannot start normally or the oil temperature is required, a heater should be installed to increase the oil temperature.
