What are the characteristics of the Oil Filter that can be used to restore oil?

We mainly explain the main characteristics of the oil that is filtered by the filter, that is, the main characteristics of the insulating oil and the turbine oil, that is, the Oil Filtration can be recovered by the filtered oil treatment.

Oil Filtration

1. Lubrication performance. For turbine oils, choosing the right viscosity is an important factor in ensuring proper lubrication of the unit. Therefore, it is required not only that the turbine oil has good lubricating properties, but also that the viscosity-temperature characteristics are required to be good, that is, the viscosity is not required to change with sudden changes in temperature.

2. Electrical performance. Power oil has certain electrical properties. The general evaluation of the electrical properties of insulating oil is the breakdown voltage, dielectric loss factor, volume resistivity, gassing and so on. If the above electrical performance does not meet the requirements of the index, the safe operation of the equipment cannot be guaranteed, and the oil cannot be used at all.

3, high temperature and low temperature safety. The high temperature safety of oil is usually expressed in terms of flash point. The lower the flash point, the greater the volatility of the oil, the less safety. Therefore, there are strict requirements and regulations on the flash point of insulating oil and turbine oil. Those who fail will not be allowed to use it. For outdoor insulating oil, especially for oil switch oil, good low temperature fluidity and low freezing point are required. Turbine oil filtered by oil filter machine also needs good anti-emulsification performance, rust resistance and foam resistance. Performance to ensure safe operation of the equipment.

4. Antioxidant stability. Generally, the operating oil temperature of the insulating oil in the transformer is about 60 to 80 ° C, and it is often in contact with air, and is also affected by electric field, corona, etc., the oil is subject to heat aging and electric aging; the turbine oil is running. The medium temperature is about 60 ° C, and it is directly in contact with air, metal, etc., and the oil has a fast circulation speed in the unit, and the oil is also aging. Therefore, the oil has good oxidation stability, and the insulating oil is generally required. Turbine oil can be used for 10 to 15 years using 10 to 20 years.
