Introduction to oil mist lubrication
Thread Content
Oil mist lubrication is a new type of centralized lubrication method that has been included in the lubrication standards for API610 pumps. By utilizing the energy of compressed air streams, the lubricating oil is atomized into oil mist particles with a size of 1–3 μm, and these particles are conveyed through the system pipes at a speed of less than 7 m/s. The conveying pressure remains between 2 Kpa and 20 Kpa, and the transmission distance can reach 150 meters. At the lubrication points, a suitable condensing nozzle is used to convert the oil mist into larger particles or oil droplets, which then deposit on the surface of the medium being lubricated. Principle of oil mist lubrication atomization. When dry air passes at high speed through a venturi or vortex tube, lubricating oil is siphoned from the oil tank into the airflow, where it is broken up by the compressed air into uneven oil particles. The larger oil particles fall back into the oil reservoir due to gravity, while the finer oil mist particles are carried by the compressed air to the areas that require lubrication. The oil mist lubrication system is mainly suitable for lubricating friction pairs such as rolling bearings, sliding bearings, gears, worm gears, sprockets, and sliding guides in industries such as petroleum, petrochemicals, metallurgy, machinery manufacturing, and light textiles. The main lubrication equipment includes centrifugal pumps, motors, fans, crushers, grinders, dryers, rolling mills, textile machines, etc.
Many companies have already adopted this approach, provided that the shaft seals of the pumps are airtight; otherwise, oil mist can cause leaks
I’ve studied it; there’s very little material available on this topic at the moment
The oil seal has been slightly modified, but it remains basically the same as before. As for the level of sealing you mentioned, I’m not quite sure; under normal conditions, oil mist does escape, and now there’s a recovery system in place to capture that oil mist
If the original oil slinger lubrication is replaced with pure oil mist lubrication, does the oil seal in the bearing housing need to be adjusted? ? ? If there are changes, what parts of the original bearing housing need to be adjusted? ?
The YSFT-WVMG type magnetic oil seal is primarily used in oil mist lubrication applications, and it can address the issue of shaft wear. Q649035094
