What are the effects of water in hydraulic oil?

There are a number of potentially harmful effects commonly associated with any amount of water in hydraulic oil, including surface corrosion and accelerated tiredness of metal ingredients. Since the water present in hydraulic oil may exist in three different conditions, specific effects may depend on factors such as water concentration, oil type and working temperature. Water, which is fully dissolved in hydraulic oil, is not usually associated with surface corrosion, but the high level of dissolved water can lead to accelerated metal fatigue. The existence of water in hydraulic oil can also change the physical properties of the oil, resulting in a reduced viscosity, or may even cause the ingredients to jam if the ice crystals are formed under particularly cold working conditions.

Hydraulic oils are a class of substances used to transmit energy in different types of hydraulic machines. In addition to functioning as a medium of energy transfer, Also hydraulic oil can perform a number of other tasks. These oils oftenThey use to lubricate, transmit heat and action as sealing medium. Some hydraulic oils are also designed specifically to be resistant to fire or radiation. The ability of hydraulic oil to perform these tasks is usually reduced by the presence of any water, although the specific effects of water in hydraulic oil depend on a number of factors.

When water contaminates hydraulic oil, there are three different conditions in which it can exist. Relatively small water levels can be completely dissolved in large amounts of hydraulic oil, in which case the effects are usually minimal. Surface corrosion usually does not occur due to a small amount of dissolved water, although the metal components in the system may suffer from accelerated fatigue. Studies have shown that decreased water levels from 400 parts to million (PPM) to 25 ppm C CPM so that some components can withstand about five times longer.

Each type of hydraulic oThe rolling may contain a limited amount of water in the dissolved state. After reaching this saturation point, the results are either free water or emulsion. A large amount of free water in hydraulic oil usually leads to a large surface corrosion and very high levels often cause components failure. When water in hydraulic oil is mixed into emulsion, the result is usually a clear change in the physical properties of the oil. This may result in hydraulic oil that has a different viscosity or compressibility, which may adversely affect the ability of oil to transmit energy.
