Abstract
MÉTODO E DISPOSIÇÃO DE MONITORAMENTO DE ATRITO ENTRE UMA PARTE ROTATÓRIA E UMA PARTE ESTACIONÁRIA E TURBOMÁQUINA. Trata - se de uma disposição para monitoramento de atrito entre uma parte rotatória e uma parte estacionária em uma turbomáquina giratória que compreende : pelo menos um detector de oscilações mecânicas (11, 12, 13) para medir oscilações mecânicas em pelo menos um ponto da turbomáquina , pelo menos um detector de partículas (21) par a medir a passagem de resíduos em pelo menos uma seção de uma trajetória de fluxo da turbomáquinas, e uma unidade de monitoramento eletrônico (50) , elétrica ou eletromagneticamente conectada ao detector de oscilações e ao detector de partículas (21), e disposta de modo a obter e processar sinais gerados pelo detector de oscilações e pelo detector de partículas ; em que a unidade de monitoramento eletrônico (50) usa a medição de oscilações principalmente para estimar a presença de atrito e a medição de resíduos principalmente para estimar a gravidade de atrito.
