Experimental research of energy efficiency of electro-drive pumps of the water supply system of the pool

Abstract

The article deals with the questions of providing of maximal energy efficiency of electro-drive chempumps through the experimental measuring of actual power arguments and their comparing to the passport values. The use of the hardwarily-programmatic providing is substantiated for registration of instantaneous values of tensions and currents of threephase fourwire network. It is discovered that deviations of indexes of quality of electric power and power parameters of pump from nominal increase the losses of energy and reduce coefficient of efficiency of the aggregate. It is therefore required to develop methods and controls of energy efficiency of ЭВН directly in place of their functioning with minimum interference with the technological process of pumping over of liquid.
