What is Oil Mist Lubrication?
Oil Mist Lubrication is a modern lubrication method that uses thin oil mist to lubricate various machinery components. It has gained popularity in industries requiring high-speed machinery, machine tool lubrication, and precision cutting. Common applications include high-speed circular saws, spindle bearings, dry cutting, aluminum processing, and tool cooling lubrication.
Key Advantages of Oil Mist Lubrication
- Enhanced Lubrication Effect: Reduces wear and tear on machine components.
- Reduced Fuel Consumption: Operates with minimal oil usage, cutting costs.
- Improved Heat Dissipation: The mist helps dissipate heat efficiently, keeping the machinery running smoothly.
- Increased Maximum Speed: Helps increase the maximum speed of rolling bearings.
- Compact and Simple Equipment: The system takes up minimal space and is easy to install.
- Low Maintenance: Minimal upkeep required, reducing overall maintenance costs.
- Centralized Management: Easy to control and monitor with a centralized system.
How Does Oil Mist Lubrication Work?
The oil mist lubrication system works by using compressed air that is filtered through an oil-water separator, passed through a pressure regulator, and atomized in the oil mist generator. The atomized oil mist is then transported through the system’s pipelines to the lubrication points.
Oil Mist Lubrication Parameters
- Particle Diameter: Typically 1-3 µm.
- Air Pressure: Set between 0.3-0.5 MPa.
- Oil Mist Concentration: Ranges from 3-12 g/m³.
- Conveying Speed: 5-7 m/s through the system.
- Distance: Maximum conveyance distance is 12 meters.
- Nozzle Distance: Nozzle should be 5-25mm away from the friction pair.
Applications of Oil Mist Lubrication
Oil mist lubrication is ideal for low oil demand applications, particularly in industries requiring low-viscosity oils and multiple lubrication points. It is compatible with various oils including:
- Environmentally friendly dry cutting oils
- Low viscosity lubricating oils
- Alcohol
- Kerosene
- Sewing machine oils
The viscosity range is generally between 10-46 cSt, making it highly versatile and adaptable to different applications.
