Ngenqubo yezezimboni, izinga lokuzenzakalelayo kwefekthri liya ngokuya likhuphuka, futhi inani elikhulu lamapayipi, izinto zokusebenza, ama-valve, njll. lakha uhlelo lokukhiqiza lwasefekthri.Ukuhlola njalo uhlelo lokukhiqiza ukuze kuqedwe izingozi zokuphepha futhi kugwenywe ukulahlekelwa okukhulu kwempilo nempahla kuyinto ehamba phambili yomsebenzi wokuphepha wasefekthri.Umthwebuli wezithombe we-sonic uthola amagagasi omsindo, izinkundla zomsindo, nemithombo yomsindo ukuze anqume ukuthi ingabe kukhona imisindo engavamile ngesikhathi sokusebenza kokusebenza kanye nokuthi ingabe kukhona ukuvuza kwamapayipi, ukuze kuvinjelwe izinkinga zokuphepha ezibangelwa ukuvuza kwamapayipi, ama-valve ephampu, njll.
Umsuka wocwaningo emiqondweni ye-acoustic imaging kanye ne-acoustic wave visualization ingalandelelwa emuva endleleni yokucabanga ye-schlieren eyasungulwa isazi sefiziksi saseJalimane u-Topler ngo-1864;okungukuthi, ngokulungisa umthombo wokukhanya, imiphumela ebangelwa amaza omsindo ingabonakala emoyeni osobala ekuqaleni.Ukuminyana komoya kuyashintsha.
Ngokuthuthukiswa kobuchwepheshe be-acoustic imaging, izithombe ze-acoustic zithuthuke zaba ama-mic array angasebenzisa imakrofoni ezwela kakhulu.Kumabhendi efrikhwensi azwakalayo kanye ne-ultrasonic, ngokusebenzisa i-algorithms yofuzo ethuthukisiwe kanye nokwakhiwa kwegxolo lokucaca okuphezulu kwenkundla ekude nobunye ubuchwepheshe, Umsindo oqoqiwe uboniswa esikrinini ngesimo semephu ye-contour yombala, ukuze imisebenzi efana nokukhipha ingxenye, imishini yokuthola umsindo ongajwayelekile, nokutholwa kokuvuza kwegesi kungenziwa.
Izinhlelo zokusebenza ze-Multi-scenario zezithombe ze-sonic
Ihlukile ekutholweni kwephoyinti kuya kwephuzu kweningi lezindlela zokuhlola, ukuhlolwa kwesitayela se-auscultation sezithombe ze-sonic kuthuthukisa kakhulu ukusebenza kahle kokuhlola.Ezinkampanini ezinezindawo ezinkulu zefekthri, izindawo eziningi ezisengozini yokuvuza kwegesi, kanye nengcindezi ephezulu kubasebenzi abahlolayo, izithombe ze-sonic ziyisixazululo esifanele.Inketho engcono kakhulu yokuthuthukisa izinga lokuphatha ukuphepha kwefekthri nokunciphisa umsebenzi wabasebenzi.
Isibonelo: embonini ye-petrochemical, ingasiza ekutholeni izinkinga zokuvuza komoya kumapayipi kanye nokuxhumana kwamavalvu;embonini yamandla, ingasiza ekuxazululeni inkinga yokukhishwa okuyingxenye kanye nokwehluleka kwemishini ezindaweni zamandla;ekuqaphelweni kwemvelo, izithombe ze-acoustic zingathola futhi zinikeze isexwayiso sangaphambi kwesikhathi ngomsindo ongajwayelekile;Ezokuthutha zomphakathi, ukuziphatha okungemthetho kokushaya ihuni kanye nokuduma kokuqhunyiswa kwamabhomu kwezimoto zasemgwaqweni kungabanjwa.
Ukusetshenziswa kwezimo eziningi zezithombe ze-sonic kubeka izimfuno eziphezulu ekuvimbeleni amanzi, ukuvikela uthuli, nokuvumelana komsindo.Ukuze kusekelwe ukutholwa okuku-inthanethi kumabhendi efrikhwensi azwakalayo kanye ne-ultrasonic anokuzwela okuphezulu, umthwebuli wesithombe se-acoustic udinga ukwenza amakhulukhulu amagobolondo avulekayo ngombhalo owodwa nowodwa ngokuya ngenani lemakrofoni kuhlu lwamakrofoni.Ukuze uvimbele amanzi emvula nothuli ekungeneni emgodini ngokuvuleka kwegobolondo, ukulimaza izingxenye ze-elekthronikhi futhi kuphazamise ukutholwa komsindo, kuyadingeka ukufaka ulwelwesi olungangeni manzi oluvumela umsindo ekuvuleni kwegobolondo:
1. Izidingo eziphakeme zokungangeni kwamanzi nezingangenisi uthuli endaweni enezimvula
2. Ukulahleka komsindo okuphansi kumabanga azwakalayo kanye ne-ultrasonic frequency
3. Ukungaguquguquki komsindo kumakhulukhulu wamakrofoni
