Modern is a collection of electric motor, the power converter and control unit. Asynchronous electric commonly used in industry as part of drive pumps, fans, compressors and other mechanisms for which it is important to maintain the engine speed. Infinitely adjustable feed pump in accordance with the current pressure in the water system is an urgent task of automatic control systems of pumping units.Frequency control allows you to control the pump by changing the speed using frequency converters (FC) of electric pumps. FC is one of the modern means of industrial automation and electric power saving.The developed system of water flow regulation is carried out by pressure gauges. The signal from the pressure sensor is compared with the refere...
