Performance Management of Local Air Purification Systems

Abstract

There were discussed issues related to improving the efficiency of cleaning the air of the working area during the implementation of engineering processes of machining products. It was established that the air cleaning efficiency can be improved by changing the air flow rate in each local cleaning device, depending on actual contamination of air in the working area. It was demonstrated that the change of air flow intensity, and hence the performance of the local cleaning device can provide by changing the sectional plane of the pipe of this cleaning apparatus by means of flap moving in manual or automatic modes. There was proposed an algorithm for increasing the efficiency of air purification system and an experimental study of the reliability of this algorithm. There was outlined an experimental set up created for carry out research, and provided a methodology of these studies. Research results shown that the effectiveness of the working area purification system and impurities sand slurries of cutting lubricants thermal destruction products can be improved by redistributing of air flows in pipelines of local purification systems through their intensity changes depending on the actual air pollution in working area.
