Мониторинг на вибрациите на каландъра на машина за хартия

Шведската хартиена фабрика Stora Enso Kvarnsveden прилага мониторинг на вибрациите на супер каландъра PM8, за да оптимизира работата му и да удължи експлоатационния живот на валяците.

Супер каландърът PM8 има дванадесет валяка на една установка, половината от които са меки (еластични) валяци, които често се износват и нагъват, поради това се нуждаят от редовно шлайфане. Износените валяци причиняват вибрации в цялата установка, което в крайна сметка увеличава износването на всички валяци. Прекомерните нива на вибрации в каландъра изискват намаляване на скоростта, което от своя страна води до потенциални намаляване на качество и производствени загуби.

Вибрирането в каландрите е трудно да се анализира чрез традиционното измерване на вибрациите. С инсталацията, описана в този случай, състоянието на отделните валяци в каландъра може да бъде внимателно наблюдавано, като по този начин се помага на операторите да определят кога и кои валяци да бъдат заменени и изпратени за шлайфане.

Чрез OPC показанията на вибрациите се експортират от системата за онлайн наблюдение към Заводската информационна система (MIS), инсталирана в контролната зала на календара, където операторите могат лесно да следят нивата на вибрациите.

Със своите три машини за хартия PM8, PM10 и PM12, Stora Enso Kvarnsveden е една от най-големите фабрики за хартия в Швеция.
