I-Tmteck Angle Beam Transducers Intshayelelo
Uvavanyo lwe-Angle beam
Inkqubo ye-angle-beam (Shear Wave) isetyenziselwa ukuvavanya iphepha, ipleyiti, umbhobho kunye nee welds. Umdumba weplastikhi ubekwe phakathi kwento yovavanyo kunye ne-transducer enefilimu yokudibanisa phakathi kwe-transducer nesibi. Isipili seplastiki sivumela isandi sokungena kwinto yovavanyo kwikona. Isandi-somqolo emva koko siboniswa sibuyele kwi-transducer njengakwindlela yovavanyo oluthe ngqo.

Rhoqo uvavanyo lomqadi oluthe tye aluyi kufumana siphene. Umzekelo, ukuba isiphene sime nkqo kwaye sibhityile ngokwaneleyo, asizukuphinda sibonise isandi esaneleyo kwitransducer ukwazisa umvavanyi ukuba ikhona. Kwiimeko ezinje, enye indlela yovavanyo lwe-ultrasound kufuneka isetyenziswe. Enye indlela yokuvavanywa kwe-ultrasound kuvavanyo lwe-angle. Uvavanyo lwe-Angle beam lusebenzisa izehlo ezingaphaya kweedigri ezingama-90. Kuvavanyo loqhakamshelwano, ibhloko yeplastikhi ene-angled yindawo phakathi kwe-transducer kunye nento yokwenza i-angle oyifunayo. Ukuvavanywa kwe-engam beam kwiinkqubo zokuntywilisela, ibhloko yeplastikhi ayifuneki kuba i-transducer inokujikwa nje emanzini.

Ukuba i-engile yeziganeko itshintshiwe yaba yiyo nayiphi na into ngaphandle kweedigri ezingama-90, amaza akude kunye nohlobo lwesibini lweliza eliveliswayo. Lawa amanye amaza abizwa ngokuba ngamaza okucheba. Ngenxa yokuba iliza lingene ngecala, ayihambi yonke ngokuthe ngqo kuloo nto. Iimolekyuli kwinto yovavanyo zinomtsalane omnye komnye kuba eziqinileyo zinamandla eemolekyuli. Iimolekyuli ezithwala isandi zitsala kwiimolekyuli zazo. Ngenxa ye-engile, ezo molekyuli zithwala isandi zitsalwa ngokutsala imikhosi kwicala elingqamene nolwalathiso lomtshangatshangiso. Oku kuvelisa amaza okucheba, okanye amaza iimolekyuli zawo ezihamba zisiya kwicala lomlanjana.
Uvavanyo lwe-Angle beam kunye notshintsho kwi-angle yeziganeko zikwadala ezinye iingxaki. Khumbula ukuba xa iliza libetha umphezulu engile, liyakuphinda livulwe, okanye ligobe xa lingena kuhlobo olutsha. Ke, amaza okucheba kunye namaza olide aya kutsalwa kwinto yovavanyo. Isixa sokuphinda sixhomekeke kwisantya sesandi kwii-mediums ezimbini ezihamba phakathi kwamaza. Kuba isantya samaza okucheba sicotha kunesantya samaza akude, ii-angles zazo zokuphikisa ziya kwahluka. Ngokusebenzisa umthetho kaSnell, sinokubala i-engile yokuphinda sibuyele xa sisazi isantya sesandi kwizinto zethu.
I-engile ikhethiwe ukuze kuqinisekiswe ukuba kufunyanwa i-echo kwiziphene ezikrokrelwayo. Ezi zezona ziphene ziba yingozi, umz. Iiprobe angles ezisetyenziselwa ubukhulu becala ubukhulu bentsimbi zezi zilandelayo:
a. I-70 Wedge - 0.250 ukuya kwi-0.750 intshi ngobukhulu
b. I-Wedge engama-60 - i-0.500 ukuya kwi-intshi ye-2.00 ubukhulu
c. I-45 Wedge - 1.500 nangaphezulu kubukhulu
Iinkqubo eziqhutywe kwezinye ii-angles kufuneka zisetyenziswe, kuxhomekeke kwindawo yesiphene kwizinto eziphantsi kovavanyo, kwaye nakumatyala akhethekileyo kumacandelo amancinci. Ukuhamba rhoqo kufuneka kube sezantsi ngokwaneleyo ukuze kuthintelwe ukungafuneki kakhulu.
I-Angle Beam Transducers kunye ne-wedge zihlala zisetyenziselwa ukwazisa umtshangatshangiso we-shear kwizinto zovavanyo. Indlela yesandi e-angled ivumela umqadi wesandi ukuba ungene uvela ecaleni, ngaloo ndlela uphucula ukubonakala kweziphene kwiindawo ezijikeleze nge welding.
