Not all hydraulic oils are suitable for hydraulic jacks. As an important component of hydraulic transmission, the selection of hydraulic oil for jacks is also important. It is recommended to use original hydraulic oil, which is the key to ensuring smooth operation of hydraulic jacks. So, how should hydraulic oil be selected?

Generally speaking, the difference in hydraulic oil is mainly reflected in viscosity, which is itself affected by temperature. Low temperature will reduce the activity of molecules, making hydraulic oil more viscous, while high temperature will make molecules more active, making hydraulic oil thinner and thicker. It is based on this rule that we can make such a choice for hydraulic oil.

When the temperature is low, we can choose hydraulic oil with lower viscosity, so that at low temperatures, its viscosity will increase slightly, just to meet the appropriate requirements. When the temperature is high, we can choose hydraulic oil with higher viscosity, so that at high temperatures, its viscosity will decrease slightly, just to meet the appropriate requirements.
