Injection molding machine temperature rise is too high Five hazards: the mechanical heat distortion; reduce the viscosity of oil; rubber seal deformation; accelerate oil oxidation deterioration; but also make the air component pressure drop. A: the mechanical deformation of the heat: hydraulic components of the thermal expansion coefficient of different moving parts due to its smaller and stuck with trainee, causing movement failure, affecting the hydraulic system of transmission accuracy, resulting in deterioration of the quality of parts work. Second: to reduce the viscosity of the oil: Injection molding machine temperature will lead to high oil viscosity decreases, increased leakage, the volumetric efficiency of the pump and the efficiency of the entire system will be significantly reduced. Due to the reduced viscosity of the oil, sliding films and other moving parts of the film thinning and being cut, the frictional resistance increases, leading to increased wear and tear. Three: the deformation of rubber seals: injection molding machine temperature will be too high deformation of rubber seals, accelerated aging failure, reducing sealing performance and service life, resulting in leakage. Four: Accelerated oil oxidation deterioration: injection molding machine temperature will accelerate the oxidation of oil deterioration, precipitation of asphalt material, reducing the service life of hydraulic oil. Precipitates clogged damping orifice and slit valve port, resulting in pressure valve stuck and can not move, metal pipe elongation and bending, or even rupture. Five: leading to deterioration of the quality of parts work: injection molding machine temperature will lead to deterioration of the quality of the parts worse, the oil dissolved air escape, resulting in cavitation, resulting in reduced hydraulic system performance
