Oil mist lubrication and oil air lubrication are two different lubrication methods, with the main difference being the form and usage of the lubricating medium.
1. Oil mist lubrication: Oil mist lubrication is the process of transforming lubricating oil into small lubricating oil particles through a specific device, forming an oil mist, and then transporting the oil mist to the area that needs lubrication through airflow or compressed air. Oil mist lubrication is commonly used on friction surfaces of machine equipment, such as bearings, gears, sliding guides, etc. Oil mist lubrication can provide a fine lubricating film, reduce friction and wear, and also cool the friction surface.
2. Oil gas lubrication: Oil gas lubrication refers to the mixing of lubricating oil and compressed air to form an oil gas mixture, which is sprayed onto the location that needs lubrication through a spraying or cooling device. Oil air lubrication is commonly used in bearings, gears, and turbines of high-speed rotating equipment. Oil gas lubrication not only provides the lubrication effect of oil film, but also can cool high-temperature components and reduce the accumulation of heat on the friction surface.
Overall, both oil mist lubrication and oil air lubrication serve to lubricate and cool the friction surface by conveying lubricating oil in a specific form. Their difference lies in the form and application method of the lubricating medium. Oil mist lubrication is transported through the atomization form of lubricating oil, while oil gas lubrication is a mixture of lubricating oil and compressed air to form a jet of oil gas mixture. The specific choice of lubrication method should be determined based on the characteristics, working conditions, and lubrication needs of the equipment.
