Abstract

ANEL DE DESGASTE SUBSTITUìVEL PARA UMA BOMBA CENTRìFUGA DE TUBO PILOTO, BOMBA CENTRìFUGA DO TIPO TUBO PILOTO E MéTODO PARA REPARAR O CONJUNTO GIRATóRIO DANIFICADO DE UMA BOMBA CENTRìFUGA. Em uma bomba centrífuga do tipo tubo piloto, um anel de desgaste substituível é posicionado no conjunto giratório da bomba naquela área do invólucro giratório que está mais sujeita à erosão a partir do processamento de fluidos abrasivos pela bomba de tubo piloto, O anel de desgaste substituível pode ser substituído de forma fácil e rápida quando erodido, desse modo eliminando-se a necessidade de substituir o invólucro giratório da bomba e eliminando-se a necessidade de se tornar a equilibrar a bomba o que é dispendioso e demorado.
