What are the dangers of excessive temperature rise of the woven bag granulator and how to eliminate it?

① Thermal deformation occurs in the machinery, and the moving parts with different thermal expansion coefficients in the hydraulic components become stuck due to the smaller fitting clearance, causing movement failure, affecting the transmission accuracy of the hydraulic system, and resulting in poor working quality of the components.

② The viscosity of the oil will be reduced, leakage will increase, and 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 on moving parts such as slide valves becomes thinner and cut, and frictional resistance increases, leading to increased wear.

③Deform the rubber seal, accelerate aging and failure, reduce sealing performance and service life, and cause leakage.

④ Accelerate the oxidative deterioration of the oil and precipitate asphalt substances, reducing the service life of the pressure reading oil. The precipitates clog the small holes and slot valve ports, causing the pressure valve to become stuck and unable to operate, and the metal pipeline to stretch, bend or even break.

⑤ The air separation pressure of the oil is reduced, and the dissolved air in the oil escapes, causing air pockets, which reduces the working performance of the hydraulic system.
