ELIMINATION OF ENERGY LOSSES IN PUMPING INSTALLATIONS BY MEANS VARIABLE FREQUENCY DRIVE
Keywords:Pressure, automatic control system, pressure sensor, proportional-integral controller, pump unit, pump speed, pressure, water taps, dead zone.
This article addresses the issues of the economical mode provided by pressure stabilization in the fluid supply system of pumping units.It is shown that the main control parameter in systems stabilizing the pressure in the network is the pressure at the dictating point. It is proved that the stabilization of the pressure at the dictating point provides the necessary minimum pressure in the network and reduces the energy consumption spent by the pumping station for water supply.
