Изобретение относитс к системам регулировани двухниточного парогенератора в период пуска, обеспечивающим поддержание расхода воды по ниткам и давлени в трак1Ре парогенератора в данном режиме.The invention relates to a double-stranded steam generator control system during the start-up period, which maintains the flow of water through the threads and the pressure in the steam generator's track in this mode.
Известна система автоматического регулировани питани двухниточного парогенератора в процессе пуска с клапанами сброса на каждой нитке, содержаща регул тор производительности питательного насоса, два регул тора питани , каждый из которых св зан со своим клапаном сброса, и датчики расхода и давлени воды в каждой нит ке 1.A system is known to automatically control the power supply of a double-stranded steam generator during start-up with relief valves on each line, containing a feed regulator for the feed pump, two feed regulators, each of which is associated with its own relief valve, and flow and pressure sensors in each string 1 .
Недостатком известной системы вл етс то, что дл устойчивой работы системы требуетс дальнейщее увеличение перепадов на клапанах сброса, которые при этом значительно прикрыты, расходные характеристики их неоднозначны, воздействие регул торов на них приводит к значительным динамическим отклонени м расхода и обеспечить удоблетворительное качество регулировани не удаетс .A disadvantage of the known system is that for the stable operation of the system, a further increase in the drops on the relief valves, which are significantly covered, their flow characteristics are ambiguous, the effect of the regulators on them leads to significant dynamic deviations of the flow rate and ensure a satisfactory quality of regulation is not successful. .
Целью изобретени вл етс повыщение качества регулировани системы.The aim of the invention is to increase the quality of system regulation.
Эта цель достигаетс тем, что датчики давлени воды подключены к регул тору производительности питательного насоса, а датчики расхода воды - к свое.му регул тору питани .This goal is achieved by the fact that the water pressure sensors are connected to the feed pump capacity controller, and the water flow sensors are connected to their own feed controller.
На чертеже приведена схема системы.The drawing shows a diagram of the system.
Система автоматического регулировани питани двухниточного парогенератора в процессе пуска с клапанами сброса 1 и 2 на каждой нитке 3 и 4 содержит регул тор 5 производительности питательного насоса 6, два регул тора 7 и 8 питани , каждый из The automatic power control system of the double-stranded steam generator during the start-up process with the relief valves 1 and 2 on each line 3 and 4 contains the capacity regulator 5 of the feed pump 6, two power regulators 7 and 8, each of
10 которых св зан со своим клапаном сброса 1 и 2 соответственно, и датчики расхода 9 и 10 и давлени 11 и 12 воды в каждой нитке 3 и 4. Датчики 11 и 12 давлени воды подключены к регул тору 5 производительности питательного насоса, а датчики 10 of which are connected to their relief valve 1 and 2, respectively, and flow sensors 9 and 10 and water pressure 11 and 12 in each line 3 and 4. Water pressure sensors 11 and 12 are connected to feed pump capacity controller 5, and sensors
15 9 и 10 расхода воды - к регул торам питани 7 и 8 соответственно. Регул тор 5 соединен с клапаном 13 привода 14 питательного насоса 6.15 9 and 10 of the water flow are to the power regulators 7 and 8, respectively. The controller 5 is connected to the valve 13 of the actuator 14 of the feed pump 6.
Система работает следующим образом.The system works as follows.
При уменьшении расхода по нитке 3 ре20 гул тор 7 питани , получив сигнал от датчика 9 расхода воды, открывает клапан 1 сброса и увеличивает расход по этой нитке.When reducing the flow in line 3 of the re20 power supply 7, after receiving a signal from the water flow sensor 9, opens the reset valve 1 and increases the flow in this line.
