Failure Analysis of Blow Molding Machine Temperature Rise in Hollow Blow Molding Plant Hollow Blow Molding Plant In the process of production and processing, it is very important to do a good job in temperature control of the hollow blow molding machine. Hollow Blow Molding Plant It is not only necessary to let the hollow blow molding machine reach a suitable temperature, but also to control the heating and cooling process of the hollow blow molding machine. 1. Thermal deformation Hollow Blow Molding Plant If the temperature of the blow molding machine is too high, thermal deformation will occur. Since the thermal expansion coefficients of the moving parts in the hydraulic components are different, if the temperature of the blow molding machine is too high, the moving parts in the hydraulic components will not be able to cooperate well, and the fit gap between the moving parts will become smaller. It gets stuck during the movement and the moving parts fail to work. Failure of moving parts will affect the transmission accuracy of the hydraulic system of the hollow blow molding machine, resulting in poor working quality of the parts. 2. Reduced oil viscosity The volumetric efficiency of the pump and the efficiency of the entire system will be significantly reduced. As the viscosity of the oil decreases, the oil film of moving parts such as slide valves becomes thinner or cut, and the frictional resistance increases, resulting in increased wear. 3. Deformation of rubber seals Hollow Blow Molding Plant Improper temperature control will accelerate the aging and failure of seals, reduce sealing performance, shorten service life, and cause leakage. Accelerate the oxidative deterioration of oil. Once the oil is oxidized and deteriorated, asphaltic substances will be precipitated, reducing the service life of the hydraulic oil. The precipitated substance will block the small damping hole and the slit valve port, and the pressure valve will be stuck and unable to move. 4. Oil air separation pressure drops. The air dissolved in the oil escapes and creates pores, which affects the normal operation of the hydraulic system of the hollow blow molding machine. Hollow Blow Molding Plant The harm caused by excessive temperature rise of the blow molding machine mainly affects the hydraulic system and components of the hollow blow molding machine. But the hydraulic system is also an important component system of the hollow blow molding machine, the hollow blow molding factory The normal operation of the blow molding machine is inseparable from the cooperation of any system and components.
