In which industries can oil filters be used?

Oil filters are widely used, covering almost all industries involving the use of lubricating oil, hydraulic oil, insulating oil, fuel oil and other oil products. The following are the main application industries and specific uses:

1. Power industry

- Thermal power plants/nuclear power plants: filter turbine oil and fire-resistant oil (EH oil), remove moisture and particulate matter, and ensure stable operation of generator sets.

- Hydropower stations: treat turbine oil to prevent bearings and gears from being damaged due to oil deterioration.

- Substations: purify transformer insulating oil, improve pressure resistance, and prevent breakdown accidents.

2. Petrochemicals

- Refineries: filter crude oil and finished oil (such as diesel and lubricating oil base oil) to remove impurities and moisture.

- Chemical plants: treat hydraulic oil and compressor oil to extend equipment life and reduce downtime for maintenance.

- LNG/natural gas: purify refrigeration oil to ensure the reliability of compressors in low temperature environments.

3. Machinery manufacturing and heavy industry

- Steel mills: Filtration of hydraulic system oil of continuous casting machines and rolling mills to prevent precision valves from getting stuck.

- Mining machinery: Purification of gear oil and hydraulic oil of excavators and crushers to cope with high-dust environments.

- Shipbuilding industry: Filtration of main engine lubricating oil and fuel oil to reduce engine wear.

4. Transportation

- Railways: Online filtration of diesel and gear oil for diesel locomotives.

- Aviation: Precision purification of aircraft hydraulic oil and aviation lubricating oil (a high-precision oil filter is required).

- Automobile manufacturing: Oil maintenance for the production line hydraulic system and test bench.

5. Manufacturing industry

- Injection molding/die-casting machines: Keep hydraulic oil clean to avoid damage to precision molds.

- Machine tool processing: Circulation filtration of spindle lubricating oil and guide rail oil to improve processing accuracy.

6. Renewable energy

- Wind power: Filtering wind turbine gearbox lubricating oil to cope with maintenance problems in remote areas.

- Solar energy: Thermal oil purification for solar thermal power plants.

7. Military and aerospace

- Tanks/ships: Dehydration and impurity removal of high-viscosity military lubricants.

- Rocket fuel: Precision filtration of special fuels (explosion-proof design required).

8. Food and medicine

- Food processing: Edible oil filtration (food-grade filter material required), or packaging machinery hydraulic oil maintenance.

- Pharmaceutical factory: Compressor lubricant oil treatment in a sterile environment.

9. Other industries

- Paper mill: Steam turbine lubricant oil purification.

- Cement plant: Large reducer gear oil filtration.

- Laboratory: Purification and regeneration of oil products for scientific research.

Key application scenarios

- New oil treatment: Factory oil may contain impurities and needs to be filtered before refilling.

- Operation and maintenance: Online or offline filtration to extend the oil change cycle.

- Waste oil regeneration: Recycle old oil, remove moisture, acidity and particulate matter.

Selection suggestions

Different industries require specific oil filter types:

- High-water oil → Vacuum oil filter

- High-precision requirements → Precision filter cartridge oil filter

- Flammable environment → Explosion-proof oil filter

The oil purification equipment can be selected according to the oil type (e.g. turbine oil, hydraulic oil, insulating oil) and the degree of contamination (particles, moisture, air).
