Description
с выходом на обмотку возбуждени двигател 11.with access to the motor winding 11.
Схема работает следующим образом.The scheme works as follows.
При изменении плотности мииераловатного ковра, проход щего между приншмными роликами 5, сигнал, пропорцио-нальный отклонению плотности от заданной, поступает от датчика - плотномера 12 в цепь управлени главного магнитного усилител 14, который, в свою очередь, измен ет скорости всех трех конвейеров в сторону устранени возникщего возмущени , сохран при этом заданное соотнощение скоростей.When the density of a microfibre carpet passing between the pinch rollers 5 changes, the signal proportional to the density deviation from the setpoint comes from the sensor — the density meter 12 — into the control circuit of the main magnetic amplifier 14, which in turn changes the speeds of all three conveyors in side of eliminating the disturbance that has arisen, while maintaining the specified ratio of speeds.
Однако ввиду запаздывани в первом контуре регулировани .невозможно только за счет этого контура достичь требуемой плотности ковра, поэтому введен второй контур, осуществл ющий точную регулировку плотности ковра за счет изменени скорости конвейера 9 камеры термообработки 10 по отношению к двум предыдущим конвейерам 3 и 6, путем подачи управл ющего сигнала, пропорционального первой производной изменени плотности, поступающего от датчика плотномера 13 на корректирующий маг итный усилитель 15, питающий оомотку возбуждени двигател 11.However, due to the lag in the primary control loop, it is impossible only due to this circuit to achieve the required density of the carpet; supplying a control signal proportional to the first derivative of the change in density, coming from the sensor of the density meter 13 to the correcting magnetic amplifier 15, which supplies the excitation shaft of the engine eleven.
Предложенный способ, автоматической стабилизации плотности мннераловатного ковра.The proposed method, the automatic stabilization of the density of the laminate carpet.
реализаци которого осуществл етс двум контурами регулировани , обеспечивает поддержание плотности минераловатного ковра с требуемой точностью. the implementation of which is carried out by two control loops ensures that the density of the mineral wool carpet is maintained with the required accuracy.
