What are the oil purifiers for filtering high-viscosity lubricating oil?

Oil filters for filtering high-viscosity lubricating oils need to have heating functions, high flow rates, and high filtration accuracy. The following are several common types of oil filters:

1. Plate and frame oil filter

- Features: The filter chamber is formed by alternating filter plates and filter frames, with a large filtration area, suitable for high-viscosity lubricating oils.

- Advantages: Simple structure, easy maintenance, and large filtration area.

- Disadvantages: More manual operations and low degree of automation.

2. Vacuum oil filter

- Features: Using vacuum dehydration technology to remove moisture and gas from the oil, suitable for high-viscosity lubricating oils.

- Advantages: Efficient dehydration and degassing, high filtration accuracy.

- Disadvantages: Complex equipment and high cost.

3. Centrifugal oil filter

- Features: Separates impurities and moisture from the oil through centrifugal force, suitable for high-viscosity lubricating oils.

- Advantages: No filter element required, low maintenance cost, and large processing capacity.

- Disadvantages: Large equipment size and high energy consumption.

4. Pressure oil filter

- Features: Use pressure to push the lubricating oil through the filter element, suitable for high-viscosity lubricating oil.

- Advantages: High filtration accuracy and fast processing speed.

- Disadvantages: The filter element needs to be replaced regularly, and the maintenance cost is high.

5. Gear oil filter

- Features: Provide high pressure through the gear pump to push the high-viscosity lubricating oil through the filter element.

- Advantages: Suitable for extremely high-viscosity lubricating oil, strong processing capacity.

- Disadvantages: High equipment cost and complex maintenance.

6. Bag oil filter

- Features: Use filter bags to filter lubricating oil, suitable for high-viscosity lubricating oil.

- Advantages: Large filtration area, large processing volume, easy replacement.

- Disadvantages: Relatively low filtration accuracy, suitable for coarse filtration.

7. Electrostatic oil filter

- Features: Use electrostatic field to adsorb tiny particles in the oil, suitable for high-viscosity lubricating oil.

- Advantages: High filtration accuracy, no filter element required.

- Disadvantages: Complex equipment and high cost.

8. Magnetic oil filter

- Features: It uses magnetism to absorb ferromagnetic particles in the oil, suitable for high-viscosity lubricating oil.

- Advantages: No filter element is required, and the maintenance cost is low.

- Disadvantages: It is only suitable for lubricating oil containing ferromagnetic particles.

Selection suggestions

- Viscosity range: Make sure that the oil filter is suitable for the viscosity of the lubricating oil.

- Filtration accuracy: ｓｅｌｅｃｔ the appropriate filtration accuracy according to the needs.

- Processing volume: ｓｅｌｅｃｔ the appropriate processing volume according to the amount of lubricating oil.

- Heating function: ｓｅｌｅｃｔ equipment with a heating function to improve filtration efficiency.

- Automation degree: ｓｅｌｅｃｔ manual or automatic equipment according to needs.

Common types of oil filters include plate and frame, vacuum, centrifugal, pressure, gear, bag, electrostatic and magnetic oil filters. When choosing, you need to consider factors such as viscosity range, filtration accuracy, processing volume, heating function and automation degree.
