Umgomo kanye nomsebenzi we-ultrasonic probe

1. Iyini i-ultrasonic probe

I-probe esetshenziswa ekuhlolweni kwe-ultrasonic iyi-transducer esebenzisa umphumela we-piezoelectric wezinto ezibonakalayo ukuze ibone ukuguqulwa kwamandla kagesi namandla omsindo.Ingxenye eyinhloko ku-probe i-wafer, okuyi-crystal eyodwa noma ishidi le-polycrystalline elinomphumela we-piezoelectric.Umsebenzi ukuguqula amandla kagesi namandla omsindo komunye nomunye.

2. Umgomo we i-ultrasonic probe

I-probe efakwe ama-wafers amabili, eyodwa njenge-transmitter enye njengesamukeli, ibizwa nangokuthi i-split probe noma i-probe ekabili ehlanganisiwe.I-probe yezinto ezimbaxambili ikakhulukazi yakhiwe isokhethi, igobolondo, isendlalelo esisele, i-chip yokudlulisa, i-chip eyamukelayo, ibhulokhi yokubambezeleka, njll. Isebenzisa i-wave wave yomsindo emile mpo ukuze iskene ucezu lokusebenza.Uma kuqhathaniswa nama-probe aqondile, ama-probe e-crystal aqondile anamandla okuthola amaphutha aseduze kwendawo;ezindaweni ezitholwayo ezimaholoholo noma ezigobile, zinomthelela ongcono wokuhlanganisa.

Isetshenziswa kumasistimu okuthola amaphutha asemi-automatic noma azenzakalelayo.Lapho i-axis ye-beam yomsindo ekhishwa i-probe i-perpendicular ebusweni bokubona, i-longitudinal wave direct beam ihlola ucezu lokusebenza;lungisa i-axis ye-beam yomsindo we-probe ukuze kwakhe i-engeli ethile nendawo yokuthola.I-beam yomsindo inqanyuliwe kusixhumi esibonakalayo phakathi kwamanzi nendawo yokusebenza.Insimbi yomsindo wegagasi ephendukile etshekile ikhiqizwa endaweni yokusebenza ukuze kuskenwe ucezu lokusebenza.I-plexiglass noma i-epoxy resin ephulukisiwe phambi kwe-chip ye-probe icutshungulwa ibe yi-arc ethile (i-spherical noma i-cylindrical), futhi i-probe yokucwiliswa kwamanzi egxilile noma egxile emgqeni ingatholakala.

3. Umsebenzi we-ultrasonic probe

1) Guqula amaza omsindo abuyisiwe abe ama-pulses kagesi;

2) Kuwukulawula isiqondiso sokusakazeka kwegagasi le-ultrasonic kanye nezinga lokuhlushwa kwamandla.Lapho i-engeli yesigameko ye-probe ishintshiwe noma i-diffusion angle ye-ultrasonic wave iguqulwa, amandla amakhulu egagasi lomsindo angajovwa endaweni emaphakathi ngama-engeli ahlukene noma ukuqondiswa kwegagasi lomsindo kungashintshwa ukuze kuthuthukiswe ukulungiswa. .Isilinganiso;

3) Ukufeza ukuguqulwa kwe-waveform;

4) Kuwukulawula imvamisa yokusebenza, efanele izimo zokusebenza ezahlukahlukene.
