Мониторинг на лагерите на челюстни дробилки със SPM HD
Миннодобивните операции включват редица критични приложения, които в случай на неизправност могат да причинят сериозни смущения в производствения процес. Едно такова оборудване е челюстната дробилка.
За период от четири месеца бяха направени тестови измервания на челюстна дробилка в подземната мина Boliden Renström в Северна Швеция. Разположена на дълбочина 840 метра, тази машина за тежки натоварвания раздробява руда при нормална работна скорост от 181 оборота в минута.
Този случай описва инсталацията за мониторинг на състоянието и констатациите по време на тестовия период. Чрез използването на софтуерен „филтър за раздробяване”, смущения от процеса на раздробяване при измерванията бяха филтрирани. Използвани са многолентови стойности, за да се разграничат честотите на лагерите от компонентите със силна модулация.
По време на пробния период бяха открити две малки повреди на външни пръстени. Поради ранния етап на повредите не бяха предприети действия, но онлайн системата остана на място и продължава внимателното наблюдение на развитието на тези повреди.
