The damage caused by the heating of hydraulic oil to the hydraulic system During the production process of the brick machine, if the heat phenomenon is found to be not dealt with in time, it will cause serious harm, mainly in the following aspects: (1) Damage to the oil film on the sliding surface of the pump and each valve body , Resulting in faster wear of the friction pair and shortening the service life of the components; (2) After the temperature of the working fluid rises, the viscosity of the working fluid decreases, the leakage of the pump increases, and the actual flow rate of the pump decreases; (3) Accelerate the oxidation of the oil film , Forming a gelatinous substance, blocking the small holes of the component, causing the hydraulic component to fail, jam, or even fail to work; (4) When the valve core and valve body material of the hydraulic valve are built, the thermal expansion coefficient is different, and the difference between the valve core and the valve body It will come out due to thermal expansion. (5) The material of the seal will age, leakage and internal leakage will increase; (6) The filter element will age early and the filtering performance will decrease.
