Description

рой управл ющий сигнал, определ емый скоростью отклонени  регулируемой температуры , т.е. формируетс  сигнал по Д -закону регулировани . Этот сигнал подаетс  на исполнительный механизм 11, установленный на трубопроводе 7 дополнительного хладоносител . При равенстве нулю величины скорости отклонени  температуры паров после конденсатора клапан 11 закрываетс . Быстродействие системы управлени  значительно возрастает при подаче дополнитель ного хладоносител  с температурой ниже .температуры основного хладоносител . При этом степень конденсации паров в дефлегмато ре и соответственно внутренн   флегма возрастает как за счет увеличени  расхода хладоносител , так и за счет увеличени  температурного перепада.a swarm of a control signal determined by the rate of deviation of the controlled temperature, i.e. a signal is generated according to the regulation D-law. This signal is applied to the actuator 11 mounted on the pipeline 7 for the additional coolant. When the value of the velocity deviation rate of the vapor temperature after the condenser is equal to zero, the valve 11 is closed. The speed of the control system increases significantly with the supply of an additional coolant with a temperature below the temperature of the main coolant. At the same time, the degree of vapor condensation in a reflux condenser and, accordingly, internal reflux increases both by increasing the coolant flow rate and by increasing the temperature difference.
