Iiprobes ze-Ultrasound ziyinxalenye ephambili yeenkqubo ze-ultrasound.
Owona msebenzi wayo usisiseko kukuphumeza uguqulo phakathi kwamandla ombane kunye namandla okuvaleka, oko kukuthi, inokuguqula omabini amandla ombane abe ngamandla okuvakala kunye namandla okuvaleka abe ngamandla ombane.Into ephambili egqiba olu chungechunge lweenguqu yikristale yePiezoelectric.I-crystal efanayo inqunywe ngokuchanekileyo kwi-element (Element) kwaye ihlelwe ngokulandelelana kwi-geometric array.
Iprobe inokuba ngamashumi ambalwa kunye namashumi amawaka eeelementi zoluhlu.Uluhlu ngalunye luqulathe iiyunithi ezi-1 ukuya kwezi-3.
Ukuze uvuyise izinto zoluhlu ukuvelisa amaza e-ultrasonic kunye nokuthatha izibonakaliso zombane ze-ultrasonic, iingcingo kufuneka zifakwe kwi-welded kwiqela ngalinye lezinto zoluhlu.
Ukuba isetyenziswe ngokungalunganga, i-solder joints inokugqweswa ngokulula ngokungena kwi-couplant okanye iphulwe yi-vibrations enzima.
Ukuze ukhokele i-ultrasonic beam ngaphandle kwe-probe ngokucokisekileyo, i-acoustic impedance (iqondo lokuthintela kwi-ultrasonic wave) kwindlela ye-acoustic beam kufuneka ilungiswe kwinqanaba elifanayo kunye nesikhumba somntu-phambi koluhlu lwezinto. , yongeza iileya ezininzi zezinto ezidibeneyo.Lo maleko yinto esiyibiza ngokuba ngumaleko ohambelanayo.Injongo yale nto kukuqinisekisa iqondo eliphezulu lomgangatho wokucinga we-ultrasound kunye nokuphelisa izixhobo ezibangelwa yi-impedance ratios.Sisanda kubona kumzobo wesakhiwo seprobe ukuba umaleko ongaphandle weprobe unegama elingaqhelekanga leLens.Ukuba ucinga ngelensi yekhamera, unyanisile!
Nangona ingeyiyo iglasi, olu maleko lulingana nelensi yeglasi yomqadi we-ultrasound (onokuthi ufaniswe nomqadi) kwaye usebenzela injongo efanayo-ukunceda ugxininiso lwe-ultrasound.I-elementi kunye ne-lens layer zihambelana ngokusondeleyo.Makungabikho luthuli okanye ukungcola.Ndingathethi moya.Oku kubonisa ukuba uhlolisiso esilubambe ngezandla imini yonke yinto eethe-ethe neethe-ethe!Yiphathe ngobunono.Umaleko ohambelanayo kunye nomgangatho we-lens ubaluleke kakhulu malunga nawo.Akuyomfuneko ukufumana izincamathelisi zerabha.Ekugqibeleni, ukuze iprobe isebenze ngokuzinzileyo nangokusisigxina, kufuneka igcinwe kwindawo evaliweyo.Khokela ngaphandle kweengcingo kwaye udibanise kwi-socket.Kanye njengophando esilubambe ezandleni zethu kwaye silusebenzise yonke imihla.
Ewe, ngoku ukuba sinokuqonda kwangaphambili kwe-probe, ekusebenziseni imihla ngemihla sizama ukwenza umkhwa olungileyo wokumthanda.Sifuna ukuba bube nobomi obude, busebenze ngakumbi, kunye nokusilela okumbalwa.Ngelizwi nje, sisebenzele.Ngoko, yintoni esifanele sinikele ingqalelo kuyo yonke imihla?Bamba kancinci, musa ukungqubeka, musa ukungquba ucingo, musa ukusonga, musa ukugoqa, Umkhenkce xa ungasetyenziswanga Kwimeko engumkhenkce, umamkeli ucima umbane ophezulu wombane kwi-array element.Iyunithi yekristale ayisekho i-oscillates kwaye i-probe iyeka ukusebenza.Lo mkhwa unokulibazisa ukuguga kweyunithi yekristale kunye nokwandisa ubomi beprobe.Friza iprobe ngaphambi kokuba uyitshintshe.Tshixa iprobe ngobunono ngaphandle kokushiya icouplant.Xa ungasebenzisi i-probe, sula i-couplant.Thintela ukuvuza, izinto zomhlwa kunye namalungu e-solder.Kufuneka kuthathelwe ingqalelo ekubulaweni kweentsholongwane Iikhemikhali ezinjengezibulali ntsholongwane kunye neearhente zokucoca zinokubangela iilensi kunye neeshethi zerabha ezikhokelela ekubeni zibe budala kwaye zibe brittle.Xa untywiliselwa kwaye ubulala iintsholongwane, kunqande ukudibana phakathi kwesokethi yeprobe kunye nesisombululo sokubulala iintsholongwane.
