Kwicandelo lokwenziwa kwemveliso yemizi-mveliso, ulawulo lomgangatho, kunye nokugcinwa kwayo, ukulinganisa ubukhulu ngokuchanekileyo kusekwe njengesiseko sokhuseleko, ukusebenza kakuhle, kunye nokuthembeka kwemveliso. Phakathi kwezixhobo zokulinganisa ezikhoyo, iigeyiji zobukhulu be-ultrasonic ziye zavela njengezinto ezibalulekileyo, zibonelela ngezisombululo ezingonakalisiyo, ezichanekileyo, neziguquguqukayo zesinyithi, iplastiki, kunye nezixhobo ezidityanisiweyo. Ezi zixhobo ziphambili zisebenzisa itekhnoloji yamaza e-ultrasonic ukuhambisa ukufundwa okuthembekileyo ngaphandle kokonakalisa umsebenzi ovavanyiweyo, okwenza ukuba zilungele ukusetyenziswa okwahlukeneyo—ukusuka kwizinto zeenqwelo-moya ukuya kwiipayipi zoshishino kunye neempahla zabathengi. Eli nqaku lihlola itekhnoloji engasemva kweegeyiji zobukhulu be-ultrasonic, iingenelo zazo ezikhethekileyo kwizixhobo ezahlukeneyo, kunye nempembelelo yazo yokuguqula kumashishini aphambili.
Kwisiseko seegeyiji zobukhulu be-ultrasonic kukho umgaqo olula kodwa onamandla: amaza e-ultrasonic ahamba kwizinto ngesantya esingaguqukiyo, kwaye ixesha elithathayo ukuze amaza abuyele umva ukusuka kumphezulu ochaseneyo wezinto lityhila ubukhulu balo. Igeyiji eqhelekileyo iqulathe i-transducer ekhupha amaza esandi aphindaphindayo (ukusuka kwi-1 ukuya kwi-10 MHz) kwaye ichonge isignali ebonakalisiweyo. Esi sixhobo sibala ubukhulu sisebenzisa ifomula: Ubukhulu = (Isantya × Ixesha)/2, apho isantya sisantya sesandi kwizinto ezithile. Le ndlela yokuvavanya okungekho ntshabalalo (NDT) isusa isidingo sokusika, ukubhoboza, okanye ukwahlulahlula izinto, igcina ukuthembeka kwezinto ngelixa ibonelela ngedatha yexesha langempela—inzuzo ebeka iigeyiji ze-ultrasonic zahlukile kwiindlela zokulinganisa zoomatshini okanye ezonakalisayo.
Xa kufikwa kwizinto zesinyithi, iigeyiji zobukhulu be-ultrasonic zigqwesile ekusombululeni imingeni eyahlukileyo yezinto zesinyithi zoshishino. Iimetali ezifana nentsimbi, i-aluminium, i-copper, kunye ne-titanium zisetyenziswa kakhulu ekwakheni, ekuveliseni iimoto, kwiipayipi zeoyile negesi, nakwizakhiwo zaselwandle, apho ubukhulu buchaphazela ngokuthe ngqo amandla kunye nokuqina kwesakhiwo. Umzekelo, kwiindawo zokucoca ioyile, iipayipi zentsimbi zichaphazeleka kukubola, uxinzelelo oluphezulu, kunye nobushushu obugqithisileyo ngokuhamba kwexesha. Iigeyiji ze-ultrasonic zinokulinganisa ngokuchanekileyo ubukhulu bodonga ukusuka ngaphandle, zichonge ukubola okanye ukuguguleka ngaphambi kokuba kukhokelele ekuvuthweni okanye ekusileleni okubi. Ngokungafaniyo nee-caliper zoomatshini ezifuna ukufikelela kumacala omabini ezinto, iigeyiji ze-ultrasonic zisebenza ukusuka kumphezulu omnye, zizenze zilungele iindawo zesinyithi ezinkulu okanye ezingashukumiyo ezifana neenqanawa zeenqanawa, imiqadi yebhulorho, okanye iinqanawa zoxinzelelo. Ukongeza, ukuchaneka kwazo okuphezulu (ngokuqhelekileyo ngaphakathi kwe-±0.01 mm) kuqinisekisa ukuthotyelwa kwemigangatho yoshishino efana ne-ASTM E114 kunye ne-ISO 9001, ebalulekileyo ekugcineni ukhuseleko kunye nokuthotyelwa kwemithetho.
Kwizinto zeplastiki, iigeyiji zobukhulu be-ultrasonic zibonelela ngezisombululo ezenzelwe wena ezichaza iimpawu ezizodwa zezinto—uxinano oluphantsi, ukuqina okwahlukeneyo, kunye nobuthathaka kumonakalo. Iiplastiki ezifana ne-PVC, i-polyethylene (PE), i-polypropylene (PP), kunye ne-ABS zifumaneka kakhulu kwiipakethe, izixhobo zonyango, iindawo zeemoto, kunye nezixhobo ze-elektroniki zabathengi. Kwi-injection molding, umzekelo, ubukhulu bodonga obuhambelanayo bubalulekile ukuthintela iziphene ezifana nokugoba okanye ukuqhekeka. Iigeyiji ze-Ultrasonic zinokulinganisa izinto zeplastiki ngexesha lokuveliswa, ziqinisekisa ukufana kunye nokunciphisa inkunkuma. Ngokungafaniyo neendlela ezisekelwe kuqhagamshelwano ezinokukrwela okanye ziguquguqule iiplastiki ezithambileyo, uvavanyo lwe-ultrasonic alungenisi, nto leyo eyenza ukuba zilungele iindawo ezibuthathaka ezifana nee-catheters zonyango okanye iifilimu zokupakisha ukutya. Ngaphezu koko, iigeyiji zanamhlanje zivumela abasebenzisi ukuba bafake isantya sesandi esithile sezinto, zibala umahluko phakathi kweeplastiki eziqinileyo (umz., iipayipi ze-PVC) kunye neepolymers eziguquguqukayo (umz., izitywini ze-silicone). Oku kuguquguquka kuqinisekisa ukufundwa okuchanekileyo kuluhlu olubanzi lweefomyula zeplastiki, ukusuka kwiiphaneli zoshishino eziqinileyo ukuya kwiifilimu ezibhityileyo neziguquguqukayo.
Ii-composites—izinto ezenziwe ngobunjineli ezenziwe ngezinto ezimbini okanye ngaphezulu ezahlukeneyo (umz., i-carbon fiber-reinforced polymer, i-fiberglass, okanye izakhiwo ze-honeycomb)—zizisa imingeni yokulinganisa eyahlukileyo ngenxa yesakhiwo sazo esineeleya kunye neempawu ze-anisotropic (iipropati ezahlukeneyo kwicala elahlukileyo). Ii-ultrasonic thickness gauges zilungele ngokukodwa lo msebenzi, njengoko zinokungena kwiileya ezininzi ngaphandle kokuphazamisa ukuthembeka kwezinto. Ii-composites zisetyenziswa ngakumbi kumashishini asebenza kakuhle njenge-aerospace, amandla omoya, kunye nezixhobo zemidlalo, apho ukunciphisa ubunzima kunye namandla kubaluleke kakhulu. Umzekelo, amaphiko e-carbon fiber composite kwiinqwelomoya afuna ukulinganiswa kobukhulu obuchanekileyo ukuqinisekisa ukusebenza kakuhle kwe-aerodynamic kunye nokhuseleko lwesakhiwo. Ii-ultrasonic gauges zinokubona ukungangqinelani kwi-layer bonding, delamination, okanye umahluko wobukhulu obunokungabonwa ngezixhobo zemveli. Ngokubonelela ngeenkcukacha ezineenkcukacha kwisakhiwo sangaphakathi sezinto, ezi gauges zinceda abavelisi ukuba bagcine ulawulo lomgangatho ngexesha lemveliso kwaye zenze amaqela olondolozo akwazi ukujonga izinto ezidibeneyo ukuba ziyaguga okanye zonakaliswe ngokuhamba kwexesha.
Ngaphandle kweenzuzo zazo zezinto eziphathekayo, ii-ultrasonic thickness gauges zibonelela ngeempawu ezininzi eziphucula ukusetyenziswa kwazo kumashishini. Ukuthwaleka yinzuzo ephambili: iimodeli eziphathwa ngesandla zivumela iingcali ukuba zenze umlinganiselo kwindawo kwimizi-mveliso, kwiindawo zokwakha, okanye kwiindawo ezikude, nto leyo esusa isidingo sokuthutha izinto ezinkulu ziye kwilebhu. Ii-gauges ezininzi zanamhlanje zikwadibanisa iziboniso zedijithali, amandla okugcina idatha, kunye noqhagamshelo olungenazingcingo, okuvumela uhlalutyo lwedatha kunye nokuhlanganiswa kwexesha langempela neenkqubo zolawulo lomgangatho. Oku kwenza kube lula ukuhamba komsebenzi, kunciphisa iimpazamo zomntu, kwaye kwenza kube lula ukuthotyelwa kweemfuno zamaxwebhu. Ukongeza, ukuqhubela phambili kwitekhnoloji ye-transducer—njenge-dual-element transducers kwiindawo ezirhabaxa okanye ii-transducers zobushushu obuphezulu kwiindawo ezixineneyo—kuye kwandisa ukusebenza kwee-gauges, okuzivumela ukuba zisebenze ngokuthembekileyo kwiimeko ezinzima ezifana nee-foundries, amaqonga aselunxwemeni, okanye izityalo zeekhemikhali.
Impembelelo yeegeyiji zobukhulu be-ultrasonic isasazeka kumacandelo angenakubalwa. Kwi-aerospace, baqinisekisa ukhuseleko lwezixhobo zeenqwelo-moya ngokubona ukugqwala okufihlakeleyo kwi-fuselages ze-aluminium okanye ukutshintsha kobukhulu kumaphiko adibeneyo. Kwishishini leemoto, baqinisekisa ukufana kwee-bumpers zeplastiki, iibhloko zeenjini zesinyithi, kunye neephaneli zomzimba ezidibeneyo, bephucula ukusebenza kwezithuthi kunye nobude bexesha. Kunyango lwamanzi kunye nemibhobho, bajonga ubukhulu beepayipi ze-PVC kunye nentsimbi, bethintela ukuvuza kwaye baqinisekise ukusebenza kakuhle kweenkqubo zokusasaza amanzi. Kwanakwicandelo lezonyango, badlala indima ebalulekileyo ekulinganiseni ubukhulu bezixhobo zonyango zeplastiki ezifana neesirinji okanye izixhobo ezifakelweyo, ukuqinisekisa ukuhambelana kwezinto eziphilayo kunye nokuthembeka kwesakhiwo.
Njengoko amashishini eqhubeka nokutshintsha, imfuno yezisombululo zokulinganisa ezichanekileyo, ezingatshabalalisiyo iya kukhula kuphela. Iigeyiji zobukhulu be-ultrasonic zesinyithi, iplastiki, kunye nezinto ezidityanisiweyo ziphambili kolu tshintsho, zibonelela ngomxube ogqibeleleyo wokuchaneka, ukuguquguquka, kunye nokusebenza kakuhle. Ukukwazi kwazo ukuziqhelanisa nezixhobo ezahlukeneyo kunye nezicelo, kunye nophuhliso oluqhubekayo lwetekhnoloji, kuzenza zibe sisixhobo esixabisekileyo sokulawula umgangatho, ukugcinwa, kunye nokuvelisa izinto ezintsha. Nokuba kukwifektri, kwindawo yokwakha, okanye kwilebhu yophando, ezi geyiji zinika amandla iingcali ukuba zenze izigqibo ezinolwazi, zinciphise iingozi, kwaye zihambise iimveliso ezihlangabezana nemigangatho ephezulu yomgangatho kunye nokhuseleko. Kwihlabathi apho ukuchaneka kubaluleke ngakumbi kunangaphambili, iigeyiji zobukhulu be-ultrasonic azizo nje izixhobo zokulinganisa—zivumela ukugqwesa kuwo onke amashishini.
