Functions Of The Vacuum Lube Oil Purifier

Writer： Kaiqian Oil Purifier Release time：2025-11-03 15:30 Clicks：

   The vacuum lube oil filter is designed to purify industrial lubricating oil. Its primary function is to remove particles, water, gases, and contaminants from the oil, thereby restoring or maintaining its performance and extending the life of the lubricant system.

Main Function

1. Deep Dehydration:

Utilizing a vacuum negative pressure environment, the boiling point of water is significantly lowered, allowing stubborn free water, emulsified water, and dissolved water in the oil to evaporate rapidly at a lower temperature. The resulting water vapor is extracted and condensed by the vacuum system.

2. Efficient Degassing:

Under vacuum, air (primarily oxygen and nitrogen) dissolved in the oil rapidly precipitates due to the reduced pressure, forming bubbles that are then extracted by the vacuum system. This effectively addresses issues such as cavitation, vibration, accelerated oil oxidation, and reduced heat dissipation caused by dissolved gases.

3. Precision Filtration of Solid Particles:

Equipped with a multi-stage, high-precision filter element, the primary filter element removes larger particles, protecting the pump unit and fine filter element. The fine filter element deeply removes fine solid contaminants such as metal debris, dust, sludge, and colloids, restoring the oil cleanliness level (e.g., ISO 4406, NAS 1638).

4. Improves oil performance and extends oil life:

By comprehensively removing moisture, gas, and solid particles, key oil performance indicators such as lubricity, oxidation resistance, anti-foaming, and heat dissipation are significantly restored or improved.

5. Protecting equipment and reducing maintenance costs:

Clean, dry lubricating oil significantly reduces equipment wear (such as bearings, gears, and hydraulic pumps/valves), corrosion, sludge formation, and filter clogging.

Industrial Lube Oil Purifier 

Applicable Lubricant Oil Types

1. Industrial Gear Oil:

Used in various speed reducers and gearboxes. Susceptible to moisture and particle contamination, leading to wear and pitting.

2. Hydraulic Oil:

Widely used in hydraulic systems of construction machinery, injection molding machines, machine tools, and other equipment. It has extremely high requirements for moisture, gas, and cleanliness, directly impacting system response, accuracy, and component life.

3. Turbine Oil:

Used in the lubrication and speed control systems of steam and gas turbines in power plants. It has extremely stringent requirements for moisture content, air release properties, anti-foaming properties, and cleanliness.

4. Machinery Lubricant oil:

Lubricant for the lubrication systems of large equipment (such as paper machines and rolling mills) and general mechanical equipment.

5. Compressor Oil:

Lubricant for certain types of air compressors or process gas compressors, requiring control of moisture and oxidation products.

6. Refrigerator Oil:

Lubricant in refrigeration systems requires strict moisture control to prevent ice blockage and corrosion.

   In short, vacuum oil purifiers are widely used in the purification of various industrial lubricants such as gear oil, hydraulic oil, turbine oil,  and circulating oil. They are the most effective equipment for solving water, gas, and solid contamination problems. They are key maintenance tools for ensuring the healthy, reliable, and economical operation of lubrication systems. When selecting and using them, it is necessary to consider the oil characteristics and specific contamination conditions. Please contact Kaiqian for professional suggestions.
