How to deal with oil filter element blockage？

The clogging of the filter element of the oil filter is a common problem, which will lead to a decrease in filtration efficiency and even equipment shutdown. The following are the reasons for the clogging of the filter element and the treatment methods:

 1. Reasons for the clogging of the filter element

- Severe oil pollution: There are too many impurities in the oil, which exceeds the dirt-holding capacity of the filter element.

- Improper filter element selection: The filter element precision is too high or the material is not suitable for the current oil.

- Excessive oil viscosity: High viscosity oil has poor fluidity and is easy to clog the filter element.

- Excessive use of the filter element: The filter element is not replaced in time, resulting in excessive clogging.

- Poor equipment operating environment: There is a lot of dust or pollutants in the working environment, which accelerates the clogging of the filter element.

 2. Treatment methods for clogging the filter element

 (1) ｒｅｐｌａｃｅ the filter element in time

- Operation steps:

1. Turn off the equipment and disconnect the power.

2. Open the oil filter housing and find the filter element.

3. Remove the clogged filter element and check its degree of contamination.

4. Install a new filter element and ensure that it is well sealed.

5. Restart the device and observe the operating status.

- Notes:

- ｓｅｌｅｃｔ a filter element model and precision that matches the device.

- Check the filter element status regularly to avoid overuse.

 (2) Cleaning the filter element (applicable to washable filter elements)

- Operation steps:

1. Remove the filter element and soak it in clean oil or detergent.

2. Use a soft brush to gently scrub the surface of the filter element to remove attachments.

3. Rinse the filter element with clean water or compressed air to ensure that there is no residue.

4. Dry or blow dry the filter element and reinstall it.

- Notes:

- Check the filter element for damage after cleaning. If damaged, ｒｅｐｌａｃｅ it.

- Non-washable filter elements (such as paper filter elements) need to be replaced directly.

 (3) Pre-treat oil

- Operation steps:

1. Pre-filter heavily contaminated oil to remove large particles.

2. Use a centrifuge or sedimentation method to separate solid contaminants in the oil.

3. Input the pre-treated oil into the oil filter for fine filtration.

- Precautions:

- Pre-filtration can extend the service life of the filter element.

- Clean the pre-filtration equipment regularly to avoid secondary contamination.

 (4) Adjust equipment operating parameters

- Operation steps:

1. Reduce equipment flow and reduce filter element load.

2. Appropriately increase oil temperature, reduce oil viscosity, and improve fluidity.

3. Monitor equipment operating pressure to avoid excessive pressure due to blockage.

- Precautions:

- Refer to the equipment manual when adjusting parameters to avoid overload operation.

 (5) Improve working environment

- Operation steps:

1. Keep the environment around the equipment clean to reduce dust and pollutants.

2. Install a protective net at the oil inlet of the equipment to prevent large particles from entering.

- Precautions:

- Clean the outside of the equipment and the surrounding environment regularly.

 3. Measures to prevent filter element clogging

- Regular maintenance: Develop a filter element replacement plan, and regularly check and ｒｅｐｌａｃｅ the filter element.

- Oil management: Regularly test the quality of oil products, and filter or ｒｅｐｌａｃｅ seriously polluted oil products promptly.

- Equipment upgrade: For highly polluted environments, consider using a multi-stage filtration system or a filter element with higher pollution capacity.

- Operation training: Strengthen operator training to ensure the correct use and maintenance of the equipment.

 4. Common manifestations of filter element clogging

- Increased equipment operating pressure.

- Significant decrease in filtration efficiency.

- Increased equipment noise or unstable operation.

- Oil cleanliness does not meet the standard.

 Summary

The treatment methods for oil filter element blockage include replacing the filter element, cleaning the filter element, pre-treating the oil, adjusting equipment parameters, and improving the working environment. Through regular maintenance and preventive measures, the occurrence of filter element blockage can be effectively reduced to ensure the efficient and stable operation of the oil filter. If the blockage problem occurs frequently, it is recommended to check the equipment configuration or oil quality, and upgrade the equipment or improve the process if necessary.
