Some characteristics of hydraulic oil in hydraulic station

2022-09-21 17:55:11

When selecting hydraulic oil, we must pay attention to the following points:

1. Viscosity of hydraulic oil

Different hydraulic stations and different working conditions have different requirements on the viscosity of oil. Generally speaking, the proper viscosity of oil can make the hydraulic pump have outstanding oil absorption capacity, reduce the pressure loss of the hydraulic station, and have outstanding smoothing effect on conflicts. Therefore, it is required that the viscosity of hydraulic oil changes slightly under the effects of pressure, temperature and shear force.

2. Compressibility of hydraulic oil

The hydraulic station requires that the compressibility of hydraulic oil be as small as possible.

3. Smoothness of hydraulic oil

The smooth effect of hydraulic oil has a great influence on its starting performance. Therefore, targeted selection is required.

4. Stability of hydraulic oil

The hydraulic station requires its oil to be stable against oxidation and hydrolysis to prolong the service life of hydraulic oil.
