Working principle of ultra-precision oil filter

Ultra-precision oil purifiers use multi-stage filtration and advanced technology to efficiently remove tiny particles, moisture and gas from the oil, ensuring high cleanliness of the oil. Its working principle is as follows:

1. Pretreatment filtration

- Coarse filtration: The oil first passes through the coarse filter to remove larger particles and impurities to protect the subsequent precision filtration elements.

2. Precision filtration

- Fine filtration: The oil enters the precision filter to remove tiny particles, usually with a precision of 1 micron or higher, ensuring high cleanliness of the oil.

3. Dehydration treatment

- Vacuum dehydration: The oil enters the vacuum separator, where the water evaporates and is separated under negative pressure, effectively removing the water.

- Coalescing separation: The tiny water droplets are gathered into large water droplets through the coalescing filter element, and then removed by the separation filter element.

4. Degassing treatment

- Vacuum degassing: In the vacuum environment, the dissolved gas in the oil is precipitated and extracted, reducing the gas content and improving the performance of the oil.

5. Adsorption filtration

- Adsorbent filtration: The oil passes through the adsorbent (such as activated alumina, silica gel, etc.) to remove residual tiny particles, moisture and acidic substances, further improving the cleanliness.

6. Post-treatment filtration

- Final filtration: The oil passes through the final filter to ensure the highest cleanliness standard and meet the requirements of ultra-precision equipment.

7. Automatic control and monitoring

- Automatic control: The system is equipped with an automatic control system to monitor and adjust the operating parameters in real time to ensure stable operation.

- Intelligent monitoring: It has real-time monitoring and alarm functions to ensure safe operation of the equipment.

8. Circulation filtration

- Circulation treatment: The oil can be circulated and filtered multiple times until the required cleanliness is reached to ensure thorough purification.

Final

Ultra-precision oil purifiers use multi-stage filtration and advanced technology to efficiently remove particles, moisture and gas from the oil to ensure high cleanliness of the oil, and are widely used in precision equipment and high-demand industrial fields.
