Abstract


In China, the oil mist lubrication technology as an advanced lubrication theory, has been used in many industries, such as petrochemical industry, metallurgy industry, etc. People are more care of oil mist lubrication technology than oil mist particles changes in the transmission line. But if oil mist particles are changing less in transmission line ? No one knows what changes. If have, whatfactors causes loss of oil mist particles in the line? If we know the cause of the loss of particles, we will improve our beneficial form oil mist lubrication pipeline. Based on these reasons, I study this subject.It is very crucial that oil mist lubrication condition in branch pipe for oil mist particles in the pipeline transmission. Therefore, oil mist particles in the pipeline transport process condition is proved with experiment in this paper, the result is the oil mist grain size along the pipeline became smaller and smaller. But attenuation of oil mist particles will lead to lubricating ability decrease of far behind the main equipment, By looking for information, it found the three major factors lead to oil mist grain size change theoretically: loss of the pressure drop; oil mist particle attach to wall; oil mist, oil mist particles collision and cohesion in the process of transmission. All in all, it is precisely because the above three causes the oil mist particles with the transmission distance increased to lead to oil mist grain size smaller and smaller.At the same time, in this paper, from what has been discussed above three factors of abstraction to express out of physical parameters, we use multiple linear regression method to establish the frictional oil mist grain size and three physical parameters of the mathematical model, which can help the established mathematical model, calculate the particle size of the oil mist.
