How to judge which oil filter is suitable based on the oil quality?

Judging which oil purifier is suitable from the oil quality mainly depends on the water content, gas content, impurity content and viscosity in the oil. The following is the specific judgment method:

1. Water content

- Low water content (such as less than 100ppm): a single-stage vacuum oil purifier can meet the needs.

- High water content (such as higher than 100ppm): it is recommended to use a two-stage vacuum oil purifier because of its stronger dehydration ability.

2. Gas content

- Low gas content (such as less than 1%): a single-stage vacuum oil purifier is sufficient.

- High gas content (such as higher than 1%): a two-stage vacuum oil purifier is more suitable and has a better degassing effect.

3. Impurity content

- Low impurity content (such as less than 0.1%): a single-stage vacuum oil purifier can handle it.

- High impurity content (such as higher than 0.1%): it is recommended to use a two-stage vacuum oil purifier because its filtration system is more efficient.

4. Viscosity

- Low viscosity oil (such as transformer oil, hydraulic oil): a single-stage vacuum oil purifier is suitable.

- High viscosity oil (such as gear oil, lubricating oil): a two-stage vacuum oil purifier is more suitable because it can better handle high viscosity oil.

5. Oil type

- Ordinary mineral oil: single-stage vacuum oil purifier is usually sufficient.

- Synthetic oil or special oil: a two-stage vacuum oil purifier is more suitable because it can remove impurities and moisture more thoroughly.

6. Oil contamination degree

- Mild contamination: single-stage vacuum oil purifier can handle it.

- Severe contamination: two-stage vacuum oil purifier is more suitable because it has stronger processing capacity.

7. Oil use environment

- General industrial environment: single-stage vacuum oil purifier is usually sufficient.

- High-demand environment (such as power system, precision equipment): a two-stage vacuum oil purifier is more suitable.

- Single-stage vacuum oil purifier: suitable for oils with low water content, gas content, impurity content and low viscosity, often used in general industrial environments.

- Two-stage vacuum oil purifier: suitable for oils with high water content, gas content, impurity content and high viscosity, often used in high-demand environments.

Choosing a suitable oil purifier according to the specific conditions of the oil quality can improve the filtration effect and extend the life of the equipment.
