Повреда на лагер на пресов валяк
В румънската хартиена фабрика Vrancart S.A. е инсталирана онлайн системата Intellinova Compact с HD технология за мониторинг на състоянието, за наблюдение на пресовата секция на машина за хартия K25. Този случай описва откриване на повреда на лагера върху един от валяците на пресата, показващ развитието на повредата за период от около шест седмици.
Предметът на казуса е лагер върху долния валяк от страната на задвижването, чиято скорост на въртене варира между 80 и 110 об/мин. Следователно този голям и много скъп лагер работи при голямо натоварване и непрекъснатото наблюдение е от особено важно значение.
В момента Vrancart S.A. инвестира в подобрения на машината за хартия K25, целящи да увеличат нейната работна скорост. Анализът на основната причина показва, че повредата на лагера най-вероятно е възникнала поради изключително голямо натоварване на пресовата секция.
HD измервателните технологии осигуриха достатъчно ранно предупреждение за извършване на планирана подмяна на лагер, което спести на клиента поне 10 000 евро.
