Which additives are used for hydraulic oil of four-column hydraulic press

The main role of the four-column hydraulic press is the driving force and working resistance, in general, the external force is much smaller than the driving force and resistance, which can be stable operation, stable operating power can be ignored, and the size of the driving force and working resistance determines the characteristics of the hydraulic press. So what are the commonly used additives for hydraulic oil of four-column hydraulic press? Let me introduce you below

Four-column hydraulic press also relies on hydraulic oil to transfer energy, then we use additives to hydraulic press is also mainly to improve the properties and performance of the bottom oil, but also to meet the various requirements of the working medium, general hydraulic oil more commonly used additives are mainly:

The first: viscosifier can increase the viscosity and viscosity index of the base oil, also known as thickener

The second: coagulant can reduce the freezing point of hydraulic oil of hydraulic press

The third: anti-wear agent can reduce the wear of the press, but also to further improve efficiency and extend life

The fourth: anti-foam agent can be used to avoid the formation of foam, and can promote the foam bursting additives

The fifth: emulsifier can make the hydraulic oil form a relatively stable emulsion, antioxidant to avoid the oxidation of hydraulic oil, rust agent is used to avoid metal rust.

Then the above are several commonly used additives for hydraulic oil of four-column hydraulic press.
