Working principle of high precision oil filter

High-precision oil purifier is a device used to remove tiny particles, water and other pollutants from oil. It is widely used in industry, electricity, machinery and other fields. Its working principle is mainly based on the combination of physical filtration and auxiliary technology. The following are the core principles and key technologies of high-precision oil purifier:

1. Core principle

1.1 Physical filtration

- Filter element filtration:

- The oil passes through a multi-layer filter element (such as glass fiber, stainless steel mesh, paper filter element, etc.), and the pore size of the filter element is usually 1-10 microns, or even smaller.

- Tiny particles are intercepted by the filter element, and clean oil passes through.

- Depth filtration:

- The filter element uses depth filtration material, the oil flows inside the filter material, and the particles are adsorbed in the filter material.

1.2 Auxiliary technology

- Vacuum dehydration:

- In a vacuum environment, the water in the oil evaporates and is extracted to achieve dehydration.

- Coalescing and separation:

- The tiny water droplets are gathered into large droplets through the coalescing filter element, and then the water is separated through the separation filter element.

- Centrifugal separation:

- The solid particles and water in the oil are separated by centrifugal force.

2. Workflow

1. Pretreatment:

- The oil passes through the coarse filter to remove large particles.

2. Precision filtration:

- The oil passes through the high-precision filter element to remove tiny particles.

3. Dehydration and degassing:

- Under vacuum, remove water and gas from the oil.

4. Coalescing and separation:

- Further remove water through the coalescing filter element and the separation filter element.

5. Output clean oil:

- The cleaned oil is output and can be used directly or stored.

3. Key technologies

3.1 High-precision filter element

- Materials: glass fiber, stainless steel mesh, paper filter element, etc.

- Precision: 1-10 microns, even up to 0.1 microns.

3.2 Vacuum system

- Function: In a vacuum environment, reduce the boiling point of water and gas in the oil, so that it evaporates and is extracted.

- Composition: vacuum pump, vacuum tank, condenser, etc.

3.3 Coalescing and separation technology

- Coalescing filter element: gather tiny water droplets into large water droplets.

- Separation filter element: separate large water droplets from the oil.

3.4 Automatic control system

- Function: real-time monitoring of oil flow, pressure, temperature and other parameters, and automatic adjustment of equipment operation status.

- Composition: PLC controller, sensor, human-machine interface, etc.

4. Application field

- Power industry: filtration and dehydration of transformer oil and turbine oil.

- Machinery manufacturing: purification of lubricating oil and hydraulic oil.

- Petrochemical: precision filtration of fuel and lubricating oil.

- Aerospace: Purification of aviation hydraulic oil and lubricating oil.

5. Advantages of high-precision oil purifier

- It can remove particles of 1 micron or even smaller.

2. Efficient dehydration:

- Through vacuum and coalescence separation technology, water can be completely removed.

3. High degree of automation:

- Equipped with automatic control system, easy to operate.

4. Extend oil life:

- Through purification, the service life of the oil can be extended and the replacement cost can be reduced.

6. Precautions

1. Filter element selection:

- ｓｅｌｅｃｔ the appropriate filter element according to the type of oil and the degree of contamination.

2. Regular maintenance:

- Regularly ｒｅｐｌａｃｅ the filter element and clean the equipment to ensure the filtering effect.

3. Operation specifications:

- Use the equipment strictly in accordance with the operating manual to avoid damage.

The high-precision oil purifier can efficiently remove pollutants in the oil through the combination of physical filtration and auxiliary technology, and is an ideal equipment for industrial oil purification.
