Ama-Ultrasound probes ayingxenye ebalulekile yezinhlelo ze-ultrasound.
Umsebenzi wayo obaluleke kakhulu ukuzuza ukuguqulwa okuhlanganyelwe phakathi kwamandla kagesi namandla e-acoustic, okungukuthi, ingaguqula kokubili amandla kagesi abe amandla e-acoustic kanye namandla e-acoustic abe amandla kagesi.Isici esibalulekile esiqeda lolu chungechunge lwezinguquko yi-Piezoelectric crystal.Ikristalu efanayo isikwa ngokunembile ibe yi-elementi eyodwa (I-Element) futhi ihlelwe ngokulandelana kwaba uchungechunge lwejometri.
I-probe ingase ihlanganise amashumi ambalwa kanye namashumi ezinkulungwane zama-elementi afanayo.Ingxenye ngayinye yamalungu afanayo iqukethe amayunithi angu-1 ukuya kwangu-3.
Ukuze kujabulise izakhi ze-array ukukhiqiza amagagasi e-ultrasonic futhi kuthathwe amasignali kagesi we-ultrasonic, izintambo kufanele zishiselwe eqenjini ngalinye lezinto zohlu.
Uma isetshenziswe ngokungalungile, amalunga e-solder angagqwala kalula ngokungena kwe-couplant noma aphulwe ukudlidliza okunzima.
Ukuze uhole ugongolo lwe-ultrasonic ngaphandle kwe-probe ngokushelelayo, i-acoustic impedance (izinga lokuvinjelwa kwegagasi le-ultrasonic) endleleni ye-acoustic beam kufanele ilungiswe ibe sezingeni elifanayo nesikhumba somuntu-ngaphambi kohlu lwezakhi. , engeza izendlalelo eziningi zezinto eziyinhlanganisela.Lesi singqimba yilokho esikubiza ngokuthi ungqimba oluhambisanayo.Inhloso yalokhu ukuqinisekisa izinga eliphezulu kakhulu lekhwalithi yokuthwebula i-ultrasound nokuqeda izinto zobuciko ezibangelwa izilinganiso eziphezulu ze-impedance.Sisanda kubona kumdwebo wesakhiwo se-probe ukuthi ungqimba olungaphandle kakhulu lwe-probe lunegama elingajwayelekile elithi Lens.Uma ucabanga ngelensi yekhamera, uqinisile!
Nakuba kungeyona ingilazi, lolu ungqimba lulingana nelensi yengilazi yomugqa we-ultrasound (ongase ufaniswe ne-beam) futhi ufeza injongo efanayo-yokusiza ukugxila kwe-ultrasound.Isici nesendlalelo selensi kunamathela eduze ndawonye.Akufanele kube khona uthuli noma ukungcola.Ingasaphathwa eyomoya.Lokhu kukhombisa ukuthi uphenyo esilubambe ngezandla usuku lonke luyinto ebucayi kakhulu futhi ebucayi!Yiphathe ngobumnene.Isendlalelo esihambisanayo kanye nesendlalelo selensi zikhetheke kakhulu ngakho.Akudingekile ukuthola izitika zenjoloba.Okokugcina, ukuze uphenyo lusebenze ngokuzinza futhi unomphela, kufanele lugcinwe endaweni ebiyelwe evalekile.Khipha izintambo bese uxhuma kusokhethi.Njengophenyo esilubamba ngezandla futhi silusebenzisa nsuku zonke.
Nokho, njengoba manje sesinokuqonda kokuqala kophenyo, ekusetshenzisweni kwansuku zonke sizama ukwakha umkhuba omuhle wokumthanda.Sifuna ibe nempilo ende, isebenze kahle kakhudlwana, futhi ibe nokwehluleka okumbalwa.Ngamafuphi, sisebenzele.Ngakho, yini okufanele siyinake nsuku zonke?Bamba kancane, ungaqhubi, ungaqhubi ucingo, ungagoqi, ungahlanganisi Ukumisa uma ungasetshenziswa Esimeni esiqandisiwe, umsingathi ucisha i-voltage ephezulu entweni yohlelo.Iyunithi yekristalu ayisanyakazi futhi uphenyo luyayeka ukusebenza.Lo mkhuba ungabambezela ukuguga kweyunithi yekristalu futhi andise impilo ye-probe.Friza i-probe ngaphambi kokuyishintsha.Khiya i-probe ngobumnene ngaphandle kokushiya i-couplant.Uma ungasebenzisi i-probe, sula i-couplant.Vimbela ukuvuza, izakhi zokugqwala namajoyinti e-solder.Kufanele kuqashelwe ekubulaweni kwamagciwane Amakhemikhali afana nezibulala-magciwane kanye nama-ejenti okuhlanza angabangela ilensi futhi ahole amashethi enjoloba ukuba aguge futhi abe brittle.Lapho ucwiliswa futhi ubulala amagciwane, gwema ukuthintana phakathi kwesokhethi ye-probe kanye nekhambi lokubulala amagciwane.
