How to choose the appropriate filtration accuracy?
(1) Insulating oil, choose 1~5μm.
(2) Lubricating oil and turbine oil below 46﹟, choose 10~20μm.
(3) Internal combustion engine oil and gear oil, choose 20~50μm.
For example, insulating oil must be filtered through high precision to achieve a high insulation value, while large-module gears have much more extensive requirements for impurities.
High-viscosity oil cannot pass through fine filters and needs to reduce accuracy.
If one-sided emphasis is placed on oil cleanliness and a fine filter is used, operating costs will inevitably increase. Because:
(1) The filter element is often blocked and needs to be cleaned or even replaced frequently.
(2) Increasing the shaft pressure allows the oil to pass through the filter faster, but this often damages the filter element.
(3) Add a preheating oil tank to increase the temperature and reduce the viscosity.
