Consumption power by pumping unit with adjustable electric is determined by the chosen algorithm and network control. This requires careful analysis of phenomenon of cell loss in power channel. To determine the energy losses in asynchronous motors must know the variation of motor current during transient or analytical expression change of speed over time and reliable data stator winding in case of change of temperature. Energy losses in the pump may determined by the data input and output. Non-availability of some parameters complicates the identification process energy indicators. Dependence of head loss hydraulic sources of productivity and dependence of slip on the working of the engine section of the mechanical characteristics are parabolic in nature. In this work the studies energy processes, which taking place in electromechanical transducers, and centrifugal pumps. The use of mechanical characteristics of asynchronous the electric pump and pressure characteristics can solve the problem determine the energy loss in the electromechanical system. |
