Lubrication technology: Design of oil mist lubrication system

oil mist refers to oil particles suspended in high-speed air jet flow. The oil mist lubrication system is to pass the dry compressed air introduced by the pipeline into the oil mist generator, use the venturi tube or vortex effect, and use the compressed air carrier to atomize the lubricating oil into fine oil particles suspended in the jet stream of high-speed air (about 6m/s below, the pressure is about 2.5 ~ 5kpa), forming dry oil mist, and then use the condensation nozzle near the lubrication point, Make the oil mist reach the pressure of 0.1MPa through throttling, and the speed is increased to more than 40m/s. The formed wet oil mist is directly directed to the surface of each lubricating point to form a lubricating oil film, while the air escapes into the atmosphere. The oil mist particle size of the oil mist lubrication system is generally 1 ~ 3 μ m. DuPont air pipe: the material must reduce the heat line pressure to 0.3 ~ 0.5MPa, and the conveying distance is generally not more than 30m

oil mist lubrication system can be divided into fine mist type and oil drop type according to different condensation effects of oil mist. Oil drop lubrication system is also called oil air lubrication system at present. The main difference between oil-gas lubrication and oil mist lubrication is that the lubricating oil is not atomized, but enters the lubricating point in drops, and the particle size of the oil is about 50 ~ 100 μ m. The oil mist lubrication system can be used in the oil and gas lubrication system. By using the condensation nozzle that can produce oil droplets, the dry oil mist can be transformed into lubricating oil droplets for lubrication. Special oil and gas lubrication devices can also be used, The dry compressed air introduced will send a certain amount of lubricating oil to the lubrication point through the quantitative plunger BMW 7 Series car, which uses a large number of carbon fiber reinforced plastic (CFRP) distributors and nozzles (condensation nozzles). The transmission distance of oil-gas lubrication is much shorter than that of oil mist lubrication, which is generally only a few meters. The pollution degree of oil-gas lubrication to the environment is much lower than that of oil mist lubrication, and the viscosity range of lubricating oil is wider than that of oil mist lubrication
