Talking About The Selection Of Hydraulic Oil For Crimping Machine 1. Appropriate viscosity, good viscosity-temperature characteristics Viscosity is the first factor to consider when selecting hydraulic oil. Under the same working pressure, if the viscosity is too high, the movement resistance of hydraulic components will increase, the pressure drop of the pipeline and the power loss will increase; if the viscosity is too low, it will increase the volume loss of the oil drum. The internal leakage of the component increases, and the oil film of the sliding parts is thinned, the supporting capacity is reduced, and there is atomization, which overflows from the exhaust port. 2. Good lubricity (anti-wear) The hydraulic system has a large number of moving parts that need to be lubricated to prevent the wear of the relative moving surfaces, especially the hydraulic equipment with high pressure, which requires much higher anti-wear properties of the hydraulic oil. 3. Good antioxidant properties Hydraulic oil will also be oxidized during use. The acidic substances produced by the oxidation of hydraulic oil will increase the corrosiveness to metals, and the resulting sludge deposits will block filters and small gaps, causing the equipment to work abnormally. Therefore, it is required to have good of antioxidant properties. 4. Good rust and corrosion resistance Hydraulic oil will inevitably come into contact with moisture and air during use, as well as acid substances generated after oxidation, which will affect the corrosion of the metal valve core, so that the hydraulic crimping machine equipment cannot work normally. It is recommended to completely replace the old and new oil in 3-5 years.
