Повреда на външната гривна на лагер в Chemi-Washer се открива с HD технология

Този случай в българска целулозна фабрика Свилоцел разглежда откриването на повреда на лагер чрез маршрутно-базиран мониторинг на състоянието на Chemi-Washer, като се използва преносимия анализатор на данни Leonova Diamond.

След многогодишно използване на преносимия анализатор A30, Свилоцел надстрои до Leonova Diamond с HD технология за мониторинг на състоянието. Скоро след това измерванията на ударните импулси със SPM HD показаха проблем с лагера на предната реверсивна ролка с много ясни BPFO съвпадения. Три месеца по-късно лагерът беше сменен, като се констатираха сериозни повреди на външната гривна.
