The impurity filtering methods for industrial oils vary depending on the type of oil and the type of impurities. Common methods are as follows:
- Filters or filter elements: Remove solid particles through filters or filter elements of different precisions (such as 10 microns to 100 microns).
- Filter bags: Suitable for large flow filtration, filter bags can capture larger particles.
- Centrifuge: Use centrifugal force to separate impurities of different densities, often used to remove water and solid particles.
- Activated carbon: Adsorbs organic impurities such as colloids and pigments in oil.
- Diatomaceous earth: Used to remove tiny particles and colloidal substances.
- Vacuum dehydrator: Heat the oil in a vacuum environment to evaporate and remove water and light impurities.
- Electrostatic filter: Adsorbs tiny particles through an electric field, suitable for high-precision filtration.
- Additives: Add chemicals to precipitate or condense impurities for subsequent filtration.
- Coalescing filter: gathers tiny water droplets into large droplets and then separates them, often used to remove moisture.
- Magnetic filter: absorbs ferromagnetic particles in oil, suitable for oil-containing iron chips.
- Multi-layer filter material: gradually removes impurities of different particle sizes through multi-layer filter material, suitable for high-precision requirements.
- Regular replacement of filter element: ensure the continued effectiveness of the filtration system.
- Oil testing: regularly test the quality of oil products and deal with impurities promptly.
Consider the following when choosing a filtration method:
- Oil type: such as lubricating oil, hydraulic oil, etc.
- Impurity type: solid particles, moisture, colloid, etc.
- Filtration accuracy: select the appropriate accuracy according to the equipment requirements.
- Flow and pressure: ensure the filtration system can withstand the working conditions.
The life of oil products and equipment can be effectively extended by choosing a reasonable filtration method.
