CALCULATION OF THE TRANSITION PROCESSES IN THE PRESSURIZED WATER PIPES AT THE START OF THE PUMP UNIT

Abstract

The article deals with processes of transition conduit when the centrifugal pump start determination value and hydraulic impact. Proper selection of the parameters of the transition process in the regulation of the operation of the units at the pumping station increases the reliability of the entire system, except for the pump, prevents vibrations that occur in it. Vibration damage and erosion are prevented.Using the results and graphs, it is possible to choose the right electric motor for the pump unit depending on the required pressure and water supply. Technical and economic efficiency is achieved by choosing the right engine. The construction of the graphical characteristics of the pump, determined the magnitude of the hydraulic impact in the grapho-analytical method.
