Everyone understandsfour-column hydraulic pressWhat is the danger of high temperature? If you don't know, then go ahead and look! Today, I will give you a solution.
1. Thermal deformation of the four-column press. Due to the small gap of the matching gap, the moving parts with different thermal expansion coefficients in the hydraulic component are stuck, resulting in failure. It affects the transmission accuracy of the hydraulic system of the four-column press, resulting in poor working quality of the components.
2. Reduce oil viscosity, increase leakage, and reduce the volumetric efficiency and overall system efficiency of the four-column press pump. As the viscosity of the oil decreases, the oil film of the moving parts such as the spool becomes thinner and cut, and the frictional resistance increases, resulting in increased wear of the four-post press.
3. Deformation of the rubber sealing ring of the four-column press, accelerated aging failure, reduced sealing performance and service life, and caused leakage.
4, accelerate the oxidation of oil deterioration and precipitation of asphalt materials, shorten the service life of hydraulic oil. The sediment blocked the orifice and slit valve port, causing the four-post press pressure valve to seize and cannot move. The metal tube elongates and bends, or even breaks.
