The role of factory oil purification system

Function of the factory oil purification system

The factory oil purification system is mainly used for cleaning and regeneration of industrial lubricating oil, hydraulic oil, transformer oil and other oil products, ensuring efficient operation of equipment, extending oil life and reducing maintenance costs. Its main functions include the following aspects:

Remove pollutants and keep oil clean

Oil will be polluted in various ways during use, including:

- Solid particles (metal chips, dust, fiber)

- Water (free water, emulsified water, dissolved water)

- Oxidation products (sludge, colloid, acidic substances)

- Air/gas (dissolved air, bubbles)

The role of the purification system:

✅ Filter particulate matter (1~10μm) → Reduce equipment wear

✅ Dehydration and degassing (vacuum or centrifugal separation) → Prevent oil oxidation and corrosion

✅ Adsorb colloid and acidic substances (activated clay, silica gel) → Delay oil deterioration

Extend the life of oil and equipment

- Reduce oil oxidation: Removing water and metal particles can reduce the oxidation rate and extend the service life of oil by 2~3 times.

- Reduce equipment wear: Reduce mechanical friction and extend the life of key components such as bearings, gears, and hydraulic pumps.

- Avoid sludge deposition: Prevent sludge from clogging the oil circuit and keep the lubrication system unobstructed.

Case: After the hydraulic system of a steel plant adopted online oil purification, the oil change cycle was extended from 6 months to 2 years, and the equipment failure rate was reduced by 40%.

Improve equipment operation efficiency

- Optimize lubrication performance: Clean oil has better fluidity, reduces friction resistance, and reduces energy consumption by 5%~10%.

- Stabilize the hydraulic system: Reduce problems such as valve core jamming and pressure fluctuations caused by oil contamination.

- Improve cooling effect: Remove impurities in the oil, improve heat dissipation efficiency, and prevent equipment overheating.

Application scenarios:

- Hydraulic system (injection molding machine, die casting machine)

- Gearbox (wind power, mining equipment)

- Turbine oil system (steam turbine, gas turbine)

Reduce maintenance costs and reduce downtime losses

- Reduce oil change frequency: Through online purification, the cost of purchasing new oil can be reduced by 50%~80%.

- Avoid sudden failures: Oil contamination is one of the main causes of equipment failure, and the purification system can reduce unplanned downtime.

- Reduce waste oil treatment costs: Reduce waste oil emissions and comply with environmental regulations (such as ISO 4406, NAS 1638).

Comparison of economic benefits:

| Project | Without purification system | With purification system |

|---------------|------------------|----------------|

| Annual oil changes | 4 times | 1 time |

| Annual waste oil volume | 2000L | 500L |

| Equipment maintenance cost | High (frequent replacement of parts) | Low (stable operation) |

Environmental compliance and reduction of carbon emissions

- Reduce waste oil generation: Oil products can be recycled to reduce the pressure of hazardous waste treatment.

- Comply with environmental regulations, such as the EU Waste Framework Directive and China's Hazardous Waste List.

- Support sustainable development: reduce energy consumption and carbon emissions caused by new oil production.

Common types of factory oil purification systems

| Type | Applicable scenarios | Main functions |

|------------------|--------------------------------|-----------------------------|

| Centrifugal purification | Removal of moisture and large particles (ships, metallurgy) | High-speed rotation to separate impurities |

| Vacuum dehydration | Deep removal of moisture and gas (electricity, chemical industry) | Low-temperature evaporation of moisture + precision filtration |

| Electrostatic purification | Ultrafine particle removal (precision machine tools) | Electric field adsorption of particles above 0.1μm |

| Adsorption purification | Removal of acidic substances and colloids (recycled oil) | Activated clay, silica gel adsorption |

The core value of the factory oil purification system

✔ Improve oil cleanliness → Reduce equipment wear

✔ Extend oil life → Reduce oil change costs

✔ Improve operating efficiency → Energy saving and consumption reduction

✔ Reduce downtime for maintenance → Ensure production continuity

✔ Meet environmental protection requirements → Reduce hazardous waste emissions

By scientifically selecting the oil purification system, the factory can significantly improve equipment reliability, achieve cost reduction, efficiency improvement and green production.
