Description
го соединены с задаюии;.м генератором 25. Своим выходом устройство 23 управлени КЭПом св зано со входами КЭПа 24, который обеспечивает определенную длительность операции.It is connected to the task; .m by a generator 25. By its output, the CEP control unit 23 is connected to the inputs of CEP 24, which provides a certain duration of the operation.
Пример. Работа канала «Вес происходит следующим образом. Один «з генераторов 1 пр моугольных импульсов задает скорость вращени диска программного задатчика 5 с помонхью избирательного устройства 2, в качестве которого может быть использован многопозиционный переключатель. Избирательное устройство 2 коммутирует двигатель програм.много задатчика 5 с выходом того генератора, который обеспечивает необходимую программу. Далее сигнал поступает на суммирующий прибор 12, откуда сигнал поступает па регул тор 8. Аналогичным образом работают все остальные местные каналы («Температура, «Вода.-кислота).Example. The work of the channel “The weight is as follows. One "3" generator of rectangular pulses sets the speed of rotation of the disk of the software setpoint generator 5 with the Pomonghue of the selective device 2, as which the multi-position switch can be used. The selective device 2 commutes the engine programmnogo knob 5 with the output of the generator, which provides the necessary program. Then the signal goes to summing device 12, from where the signal goes to controller 8. All other local channels work in the same way (“Temperature,“ Water.-acid).
Коррекцию осуществл ют следующим образом . При отклонени х иараметров пара от заданных датчик 22 иараметров пара вырабатывает сигнал, который поступает на суммирующий прибор 14 в канале «Вода -кислота , измен сигнал от программного задатчика 7 расхода воды. Одновременно с датчика 22 постуиает сигнал и на устройство 23 уиравлени КЭПом. В рез льтате скважность сигнала, управл ющего работой КЭПа п поступающего на устройство управлени The correction is carried out as follows. When the deviations of the steam parameters from the predetermined sensor 22 and the steam parameters produce a signal that is fed to the summing device 14 in the channel “Water - acid, changing the signal from the program unit 7 of the water flow. At the same time, sensor 22 also signals a signal to device 23 of the control by CEP. As a result, the duty cycle of the signal that controls the operation of the CAP p arriving at the control device
КЭПом с задающего генератора 25, из.мен етс в соответствии с величиной поступившего сигнала, т. е. тем самым измеЕ1 етс врем операции, а значит измен етс и общий расход воды и кислоты, подаваемых на гидролиз .The CEP from master oscillator 25 changes in accordance with the magnitude of the incoming signal, i.e., thereby, the operation time is changed, and therefore the total consumption of water and acid supplied to the hydrolysis is also changed.
При умеиьщении скорости выдачи гидролизата (клапаи выдача полностью открыт) срабатывает датчик 21 скорости выдачи гидролизата , сигнал с которого поступает, во-первых , на суммирующий прибор 14 в канале «Вода-кислота, а во-вторых, на вход устройства 23 управленп КЭПом, измен при этом задани по подаче воды, кислоты и их общему расходу.When the hydrolyzate delivery rate is increased (the valve is fully open), the hydrolyzate delivery speed sensor 21 triggers, the signal from which is fed, firstly, to summing device 14 in the Water-Acid channel, and secondly, to the input of device 23 change with this task on the supply of water, acid and their total consumption.
