THE EXPERIMENTAL INVESTIGATION OF MATERIAL PROCESSING INTENSITY IN THE AUTOMATIC WASHING MACHINE

Abstract

Conducting an experimental study of the influence of the structural parameters of the drum crests on the intensity of centrifugal material processing in automatic household washing machines. Methodology. The methods used to evaluate the efficiency of washing light industry materials and the mathematical methods of experiment planning.  An experimental study of the influence of the design parameters of the drums' paddles on the
intensity of the material processing in washing mode, using mathematical methods of experiment planning. The  basis  of  the  research  method  is  the  principle  of  detecing  the  dependence  of  the  magnitude  of  the efficiency  of  the  washing  of  the  samples  on  the  duration  of  the  operation  after  reaching  a  certain temperature of the heating of the washing solution, in accordance with the current standards. Scientific  novelty.  The  parameters  and  indicators  that  need  to  be  taken  into  account  during  the development  and  preparation  of  the  experimental  study  of  the  intensification  of  washing  in  household machines  are  analyzed  and  presented.  The  regression  equation  was  developed  for  determination  of  the
calculated  values  of  the  optimization  criterion  -  an  indicator  of  the  washing  efficiency  of  samples  in  the processing of light industry materials during the washing mode. Practical significance. As a result of the experimental study, the most significant parameters that influence the efficiency of washing light industry materials in centrifugal machines were determined, namely
the  angle  of  inclination  of  the  surface  of  the  paddle  of  the  drum  and  location  of  its  paddle  on  the  shell relative to the axis of its rotation. An experimental mathematical model of the study of the intensification of material  processing  in  centrifugal  drum  devices  is  shown.  It  can  be  used  in  the  design  of  centrifugal machines of various applications.
