Reliability and durability of systems to deliver fluids, as well as other hydraulic systems depends largely on the correspondence of clean oil to the established norms. Oil can pollute both mechanical inclusions, dirt and decay products, and formed water and gases. Usually recommended to maintain the level of water absorption of up to 45%. In order to promptly determine whether treatment has developed various hydraulic sensors, including sensors determine the water content in oil pressure switches, etc. With their help staff to receive information about the state of hydraulic oils, and can take on the need to clean up. Removal of off-line mode in hydraulic systems can be produced using various filtering systems – portable, ie portable, mobile – usually on a mobile platform and fixed, embedded in the hydraulic system itself.
Each of these has advantages and disadvantages. Laptops can easily be moved due to its light weight, mobile systems are more high, but take up more space and the cost is higher. Embedded systems allow you to filter automatically, permanently maintaining the required cleanliness level of oil, which is particularly important for such hydraulic systems such as lubrication of bearings turbine power plants. Some filtration systems are equipped with control equipment, automatic control, heat-exchange devices to provide the necessary cooling properties of hydraulic oils. Ion-exchange unit can restore the acid number, thereby stopping the aging process oil. So , the choice of a specific type and model of the filtration system must be carried out with appropriate cleaning performance, its periodicity, Filtration, and have some reserve capacity. However, it is necessary to avoid obvious overcapacity filtering, as this will cause undue financial burden.
