Description

сигнал рассоглабовани  идет на блок изменени  задани  11 регул тору.the unmatched signal goes to the change block of task 11 of the controller.

Выходной сигнал регул тора формируетс  с учетом указанных параметров и направл етс  «а клапан 12, регулирующий расход теплоносител  в подогревателе. Теромопарами 13, 14 замер етс  температура в зо«ах испарени  и сигнал поступает на блоки тиристоров 15, 16, регулиругогцих напр жение в обмотках электрообогрева 17, 18. На блоки тиристоров также идет сигнал с задатчика 19 давлени . С датчика давлени  20 информаци  поступает на блок сравнени  21 с сигналом задатчика 19, и рассогласование направл етс  на блок изменени  задани  22 блоком тиристоров. Регулирующие сигналы блоков тиристоров формируютс  с учетом указанных параметров, а дл  низшей обмотки и с учетом температурыThe output signal of the regulator is formed taking into account the specified parameters and is directed to the valve 12, which regulates the flow rate of the heat transfer medium in the preheater. The thermo-pairs 13, 14 measure the temperature in the evaporation zone and the signal goes to the thyristor blocks 15, 16, the regulating voltage in the electrical windings 17, 18. The thyristor blocks also receive a signal from the pressure setting device 19. From the pressure sensor 20, the information enters the comparison unit 21 with the setpoint signal 19, and the error is sent to the change unit of the reference 22 by the thyristor unit. The control signals of the thyristor blocks are formed according to the specified parameters, and for the lower winding and taking into account the temperature

выход щего потока из аппарата, Измер емой термопарой 23.the effluent from the apparatus as measured by a thermocouple 23.
