Reasons why the oil purifier has poor dehydration effect

There are several reasons why an oil purifier might have poor dehydration (or water removal) performance. Here are some common causes:

1. Clogged or Worn-out Filters: The filters in the purifier may be clogged with impurities or have become worn out, reducing their effectiveness in separating water from the oil.

2. Improper Operating Temperature: If the temperature of the oil isn't optimal, the water may not separate easily from the oil. Oil needs to be heated to the right temperature for efficient dehydration.

3. Incorrect Pressure Settings: If the pressure is too high or too low, it can affect the separator's ability to remove water properly. Correct pressure is essential for effective water separation.

4. Contamination with Emulsified Water: If the water is emulsified (i.e., it is finely mixed with the oil), the purifier will have difficulty separating it. Emulsification occurs when water is broken into tiny droplets, making it harder for the purifier to remove.

5. Low-Quality or Poor Design of Purifier: Some purifiers may not be designed with adequate capacity or technology to handle the specific type of oil being processed, leading to poor dehydration performance.

6. Excessive Oil Contaminants: If the oil contains excessive solid contaminants or other foreign materials, it could interfere with the dehydration process and hinder the purifier's effectiveness.

7. Insufficient Purifier Capacity: If the oil purifier is undersized for the amount of oil or the water content, it may struggle to properly remove all the water.

8. Maintenance Issues: Lack of regular maintenance (e.g., cleaning, replacing worn parts) can also reduce the efficiency of the purifier over time, including its ability to remove water.

9. Chemical Additives: Some oil may contain chemical additives or emulsifiers that prevent water from separating properly, thus lowering the dehydration efficiency of the purifier.

10. Wrong Oil Type: Some oils are more difficult to dehydrate due to their composition, such as oils with higher viscosity or those that are more prone to emulsification.

To improve the dehydration effect, you may need to troubleshoot these factors, ensure proper maintenance, or consider upgrading the purifier if it’s not suitable for the task at hand.
