Basic knowledge of oil purifier filter element

The filter element of the oil filter is the core component of the oil filter. It is mainly used to filter impurities in the oil, ensure the oil is clean, and extend the service life of the equipment. The following is the basic knowledge of the filter element of the oil filter:

1. The role of the filter element

- Filter impurities: remove solid particles, metal chips, dust and other pollutants in the oil.

- Extend the life of the oil: keep the oil clean, reduce oxidation and deterioration.

- Protect equipment: prevent impurities from entering the equipment, reduce wear and failure.

2. Material of the filter element

- Paper filter element: low cost, suitable for general filtration, but short service life.

- Glass fiber filter element: high filtration accuracy, high temperature resistance, suitable for high-precision filtration.

- Metal mesh filter element: high strength, can be washed and reused, suitable for coarse filtration.

- Composite filter element: combined with multiple materials, with high precision and long life.

3. Filter element accuracy

- Filtration accuracy: refers to the minimum particle size that the filter element can filter, in microns (μm). The higher the precision, the better the filtering effect, but it may increase the oil resistance.

- Common precision: 1μm, 5μm, 10μm, 20μm, etc., ｓｅｌｅｃｔ according to needs.

4. Type of filter element

- Surface filter element: impurities are trapped on the surface, easy to clog, and need to be replaced frequently.

- Depth filter element: impurities are trapped inside the filter material, with strong dirt holding capacity and long service life.

5. Replacement cycle of filter element

- Use environment: more frequent replacement is required in seriously polluted environments.

- Oil type: different oils have different degrees of pollution, which affects the replacement frequency.

- Equipment operation: long-term high-load operation of the equipment will accelerate the clogging of the filter element.

6. Maintenance of filter element

- Regular inspection: monitor the pressure difference of the filter element, and ｒｅｐｌａｃｅ it when the pressure difference is too large.

- Correct installation: ensure good sealing to avoid leakage.

- Cleaning: some filter elements can be cleaned and reused, but attention should be paid to the cleaning method.

7. Selection of filter element

- According to equipment requirements: ｓｅｌｅｃｔ filter elements that meet the equipment accuracy and flow requirements.

- According to oil type: different oils require filter elements of different materials.

- According to working environment: special environments such as high temperature and high pressure require special filter elements.

8. Common problems

- Filter element blockage: pressure difference increases, flow decreases, and needs to be replaced in time.

- Filter element damage: filtration effect decreases, oil pollution increases, and needs to be replaced immediately.

- Improper installation: leakage or poor filtration effect, need to be reinstalled.

9. Storage of filter element

- Dry environment: avoid moisture.

- Avoid high temperature: prevent filter material aging.

- Dustproof: keep clean and avoid pollution.

10. Environmental protection treatment of filter element

- Recycling: some filter elements can be recycled and reused.

- Harmless treatment: discarded filter elements must be treated according to environmental protection requirements to avoid pollution.

Summary

The filter element of the oil filter is crucial to the normal operation of the equipment. Correct selection, use and maintenance of filter elements can effectively extend the life of equipment and improve operating efficiency.
