The harm of high temperature of single-column hydraulic press

The harm of high temperature of single-column hydraulic press

(1) The machine is thermally deformed, and the moving parts with different thermal expansion coefficients in the hydraulic components are stuck due to their smaller fitting gaps, causing action failure, affecting the transmission accuracy of the hydraulic system, and resulting in poor working quality of the components.

(2) The viscosity of the oil is reduced, the leakage is increased, 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 the moving parts such as the spool valve is thinned and cut, and the frictional resistance increases, resulting in increased wear.

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

(4) Accelerates the oxidation and deterioration of the oil, and precipitates the asphalt material, reducing the service life of the hydraulic oil. The precipitates block the damping holes and slit valve ports, resulting in the pressure valve being stuck and unable to operate, the metal pipeline being stretched and bent, or even ruptured.

(5) The air separation pressure of the oil is reduced, the dissolved air in the oil escapes, and cavitation is generated, which reduces the working performance of the hydraulic system.
