I-Dacheng Precision ibisoloko izibophelele kuphando kunye nophuhliso lwetekhnoloji entsha. Ukongeza kwezi zisombululo zovavanyo ezingentla zingonakalisi, ikwaphuhlisa itekhnoloji yokulinganisa ubukhulu be-ultrasonic. Xa kuthelekiswa nezinye izisombululo zokuhlola, ukulinganisa ubukhulu be-ultrasonic kunezi mpawu zilandelayo.
3.1 Umgaqo wokulinganisa ubukhulu be-ultrasonic
I-Ultrasonic thickness gauge ilinganisa ubukhulu obusekwe kumgaqo we-ultrasonic pulse reflection method. Xa i-pulse ye-ultrasonic ekhutshwe yi-probe idlula into elinganisiweyo ukufikelela kwi-interfaces eziphathekayo, i-wave wave ibonakaliswe kwi-probe. Ubunzima bento elinganisiweyo bunokumiselwa ngokulinganisa ngokuchanekileyo ixesha lokusasazwa kwe-ultrasonic.

Phantse zonke iimveliso ezenziwe ngetsimbi, iplastiki, izinto ezidibeneyo, i-ceramics, iglasi, i-fiber yeglasi okanye irabha inokulinganiswa ngolu hlobo, kwaye inokusetyenziswa ngokubanzi kwi-petroleum, iikhemikhali, i-metallurgy, i-shipbuilding, i-aviation, i-aerospace kunye nezinye iindawo.
3.2Aizinto eziluncedokwe uUmlinganiselo wobukhulu be-ultrasonic
Isisombululo semveli samkela ray transmission indlela ukulinganisa isixa lilonke ukutyabeka uze usebenzise ukuthabatha ukubala ixabiso lithium ibhetri electrode net ukutyabeka isixa. Ngelixa i-ultrasonic gauge ubukhulu inokulinganisa ngokuthe ngqo ixabiso ngenxa yomgaqo wokulinganisa owahlukileyo.
①I-Ultrasonic wave inokungena ngamandla ngenxa yobude bayo obufutshane, kwaye iyasebenza kuluhlu olubanzi lwezixhobo.
② I-ultrasonic sound beam inokugxininiswa kwicala elithile, kwaye lihamba ngendlela echanekileyo phakathi, kunye nokuqondisa okulungileyo.
③ Akukho mfuneko yakuzikhathaza malunga nomba wokhuseleko kuba ayinamitha.
Nangona kunjalo, ngaphandle kwento yokuba umlinganiselo wobukhulu be-ultrasonic uneenzuzo ezinjalo, xa kuthelekiswa nobuninzi betekhnoloji yokulinganisa ubukhulu i-Dacheng Precision sele izise kwimarike, ukusetyenziswa komlinganiselo wobukhulu be-ultrasonic kunomlinganiselo othile ngolu hlobo lulandelayo.
3.3 Ukulinganiselwa kwisicelo somlinganiselo wobukhulu be-ultrasonic
①I-Ultrasonic transducer: I-ultrasonic transducer, oko kukuthi, i-probe ye-ultrasonic ekhankanywe ngasentla, iyona nxalenye ephambili ye-ultrasonic gauges yokuvavanya, ekwazi ukuhambisa kunye nokufumana amaza e-pulse. Izalathi zayo ezingundoqo zokusebenza rhoqo kunye nokuchaneka kwexesha kuqinisekisa ukuchaneka komlinganiselo wobunzima. I-transducer ye-ultrasonic ye-high-end yangoku isaxhomekeke kwimpahla evela ngaphandle, ixabiso layo libiza.
②Ukulingana kwezinto: njengoko kukhankanyiwe kwimigaqo esisiseko, i-ultrasonic iya kubonakaliswa emva kwi-interfaces eziphathekayo. Ukubonakaliswa kubangelwa utshintsho olukhawulezileyo kwi-acoustic impedance, kwaye ukufana kwe-acoustic impedance kunqunywe ngokufana kwezinto eziphathekayo. Ukuba izinto eziza kulinganiswa azifani, umqondiso we-echo uya kuvelisa ingxolo eninzi, echaphazela iziphumo zokulinganisa.
③ Uburhabaxa: uburhabaxa bomphezulu bento elinganisiweyo buya kubangela i-echo ebonakaliswe ephantsi, okanye nokungakwazi ukufumana umqondiso we-echo;
④Ubushushu: i-essence ye-ultrasonic kukuba i-vibration ye-mechanical of particles medium isasazwa ngendlela yamaza, angenakuhlukaniswa ekusebenzisaneni kwamaqhekeza aphakathi. Ukubonakaliswa kwe-macroscopic ye-thermal motion of medium particles ngokwazo yiqondo lokushisa, kwaye ukunyakaza kwe-thermal kuya kuchaphazela ngokwemvelo ukusebenzisana phakathi kwamaqhekeza aphakathi. Ngoko ubushushu bunempembelelo enkulu kwiziphumo zomlinganiselo.
Ngomlinganiselo oqhelekileyo we-ultrasonic ubungakanani obusekwe kumgaqo we-pulse echo, ubushushu bezandla zabantu buya kuchaphazela ubushushu beprobe, oko kukhokelela ekukhukulisekeni kwenqanaba elinguziro legeyiji.
⑤Uzinzo: isandi somsindo kukushukuma komatshini kwamasuntswana aphakathi ngendlela yokusasazwa kwamaza. Iyakwazi ukuphazamiseka kwangaphandle, kwaye umqondiso oqokelelweyo awuzinzile.
⑥I-Coupling medium: i-ultrasonic iya kuthobisa emoyeni, ngelixa inokusasazwa kakuhle kulwelo kunye nezinto eziqinileyo. Ukuze ufumane ngcono umqondiso we-echo, i-liquid coupling medium idla ngokudityaniswa phakathi kwe-ultrasonic probe kunye nento elinganisiweyo, engafanelekanga ekuphuhliseni inkqubo yokuhlola ngokuzenzekelayo kwi-intanethi.
Ezinye izinto, ezifana ne-ultrasonic phase reversal okanye ukuphazamiseka, i-curvature, i-taper okanye i-eccentricity yobuso bento elinganisiweyo iya kuba nefuthe kwiziphumo zokulinganisa.
Ingabonwa ukuba umlinganiselo wobukhulu be-ultrasonic uneenzuzo ezininzi. Nangona kunjalo, okwangoku ayinakuthelekiswa nezinye iindlela zokulinganisa ubukhulu ngenxa yemida yayo.
3.4UInkqubela yophando lomlinganiselo wobunzima be-ultrasonicyeDachengPulungiso
I-Dacheng Precision ibisoloko izibophelele kuphando kunye nophuhliso. Kwintsimi yokulinganisa ubukhulu be-ultrasonic, iye yenza inkqubela phambili. Ezinye zeziphumo zophando ziboniswa ngolu hlobo lulandelayo.
3.4.1 Iimeko zovavanyo

3.4.2 Idatha yovavanyo
Idatha yovavanyo inikezelwa ngohlobo lwe-A-scan kunye ne-B-scan. Kwi-A-scan, i-X-axis, imele ixesha lokuhanjiswa kwe-ultrasonic kunye ne-Y-axis imele ukuqina kwamaza abonakalisiweyo. I-B-scan ibonisa umfanekiso we-dimensional-dimensional yeprofayili ehambelana nesalathiso sesantya sesandi kunye ne-perpendicular kumphezulu olinganisiweyo wento ephantsi kovavanyo.
Ukusuka kwi-A-scan, kunokubonwa ukuba i-amplitude yokubuyisela i-pulse wave ekudibaneni kwegraphite kunye ne-copper foil iphezulu kakhulu kunezinye iifom zamaza. Ubunzima be-graphite yokwambathisa bunokufumaneka ngokubala i-acoustic-path ye-ultrasonic wave kwi-graphite medium.
Ingqikithi yamaxesha e-5 yedatha yavavanywa kwiindawo ezimbini, i-Point1 kunye ne-Point2, kunye ne-acoustic-path ye-graphite kwi-Point1 yayingu-0.0340 kuthi, kunye ne-acoustic-path ye-graphite kwi-Point2 yayingu-0.0300 kuthi, ngokuchaneka kokuphindaphinda okuphezulu.
