THE EFFICIENT MANAGEMENT OF ELECTROTECHNICAL EQUIPMENT FOR THE QUALITATIVE WATER PRODUCTION TECHNOLOGICAL SCHEME
The technological scheme for the preparation of drinking water covers water intake, pre-treat-ment, cleaning with carbon and other filters - softening, disinfection, etc. As a necessary equip-ment, water treatment technology involves the use of water pumps. Effective approaches to con-trolling the functioning of electric motors of centrifugal pumps pumping the volume of water are analyzed. In work algorithms and methods of electric motor control are considered, which allow to reduce costs when using it, and also to maintain the required level of performance characteris-tics of electric drives and water pumps.Using a regulated electric drive in water supply systems allows you to modify the performance of pumps in accordance with the schedule of water intake, which in turn allows you to obtain significant savings in electricity and water, reduce the number of accidents due to pipeline rup-tures. The use of an adjustable electric drive in water pumps saves energy from 38 % to 45 %. The results of the analysis of violations with the use of asynchronous electric motors detected during the operation of a frequency-controlled drive (FСD) at pumping stations of water supply allow us to conclude that it is necessary to limit the frequency ranges of regulation. The FСD has the fol-lowing advantages: the ability to regulate the engine speed in a wide range and reduce the inrush current to almost nominal. The main function performed by the automated filter management system is the operation of the electrotechnical equipment in the filter unit in accordance with the water treatment technology.
