O‘ZBEKISTON RESPUBLIKASI OLIY VA O‘RTA MAXSUS TA’LIM VAZIRLIGI NAMANGAN MUHANDISLIK – QURILISH INSTITUTI “ZAMONAVIY MASHINASOZLIKDA INNOVASION TEXNOLOGIYALARNI QO‘LLASHNING ILMIY ASOSLARI: TAJRIBA VA ISTIQBOLLAR” mavzusida Xalqaro miqyosida ilmiy-amaliy konferensiya materiallari to‘plami III Namangan shahri 23-24 sentyabr 2022 yil 165 The principle of operation of the automatic electric drive of the centrifugal pump: in this case, one of the valves must be opened at a certain angle for the electric drive to start. When the shutter is opened, the electric drive starts in parallel mode. In order to get the required water consumption, the feedback sensor connected to the network with the control of the working machine calculates the water consumption and commands the frequency converter that controls it to work on the f 2 chart. This principle automatically saves electricity and water consumption.Ishchi formulalar: U/f=const ℎ 𝑠𝑡. = 𝐻 𝑑𝑖𝑛. + 𝐻 𝑔𝑒𝑜. + 𝑝 𝑏𝑎𝑘𝑎 𝜌𝑔 P= √3𝑈𝐼𝑐𝑜𝑠𝑓 𝐻 𝑑𝑖𝑛 = 𝐻 𝑠𝑡 + 𝑆 Q=vS 𝑛 = 60𝑓 𝑝 Summary; Automation of the pumping device provides an opportunity to save electricity and the amount of liquid. Pumps around the world consume 50-60% of electricity. If each pump is controlled by a frequency converter, electricity can be significantly saved. References 1.
