1. Defoaming properties of hydraulic oil
The four-column hydraulic press requires that the bubbles and foam produced by the hydraulic oil should be as small as possible and disappear quickly.
2. Rust resistance and corrosion resistance of hydraulic oil
Under the action of water and air, the metal surfaces of hydraulic components will rust and corrode. Particles produced by rust and corrosion will circulate in the hydraulic station, causing wear on the moving surfaces and causing the hydraulic station to malfunction. Therefore, hydraulic oil is required to have strong anti-rust and anti-corrosion properties so that the metal surface will not rust or corrode.
3. Compressibility of hydraulic oil
The four-column hydraulic press requires the compressibility of the hydraulic oil to be as small as possible.
4. Stability of hydraulic oil
The four-column hydraulic press hopes that its oil has anti-oxidation and anti-hydrolysis stability to extend the service life of the hydraulic oil.
5. Lubricity of hydraulic oil
The lubrication effect of hydraulic oil has a great influence on its starting performance characteristics.
