Abstract

"DETETOR DE DEFEITOS DAS MáQUINAS ROTATIVAS". Ferramenta portátil de diagnóstico das máquinas rotativas industriais (1), é constituída por coletor parabólico (2) de som (onda acústica na faixa de freq³ências de 20 Hz a 20.000 Hz), microfone (3) tipo-condensador, amplificador eletrónico (6), conversor analógico/digital (7), micro-computador (8) e software aplicativo (9) de diagnóstico. A função da ferramenta é descobrir e identificar sintomas de funcionamento irregular e defeitos das máquinas para os serviços de diagnóstico nas fábricas. A ferramenta compara características de freq³ência do som emitida pelas máquinas "com defeito" com as freq³ências de referência (máquina "normal"). Pode substituir ferramentas importadas de manutenção preditiva usada nas indústrias brasileiras e também, em grande parte, o ouvido humano dos bem treinados e experientes "técnicos" de diagnóstico. A presente invenção é caracterizada por: aproveitamento do som emitido pelas máquinas, coletor parabólico, inexistência de contato físico entre microfone e máquina rotativa, operação simples e facilidade de transporte, software aplicativo processável em qualquer micro-computador, algoritmo de filtro-digital baseado na teoria de predição linear autoregressiva e análise de freq³ências do som, baseado no espectro de potência do ruído-branco e no seu valor médio-móvel. Visa facilitar o planejamento de manutenção, evitando as paradas imprevisíveis."TROUBLESHOOTING DETECTION". Handheld diagnostic tool for industrial rotary machines (1), consists of parabolic sound collector (2) (acoustic wave in the frequency range 20 Hz to 20,000 Hz), condenser type microphone (3), electronic amplifier (6) , analog / digital converter (7), microcomputer (8) and diagnostic application software (9). The function of the tool is to discover and identify symptoms of malfunction and machine defects for factory diagnostic services. The tool compares sound frequency characteristics of the "defective" machines with the reference frequencies ("normal" machine). It can replace imported predictive maintenance tools used in Brazilian industries and also largely the human ear of well-trained and experienced diagnostic "technicians". The use of sound from machines, parabolic collector, no physical contact between microphone and rotary machine, simple operation and ease of transport, application software processable on any microcomputer, digital filter algorithm based on autoregressive linear prediction theory and sound frequency analysis based on the white noise power spectrum and its moving average value. Aims to facilitate maintenance planning by avoiding unforeseen downtime.
