Yuav ua li cas xaiv txoj cai ultrasonic oscillator?
Tso lus
Ultrasonic tu transducer
A. Piezoelectric wafer faib: PZT4 series nrog dub wafer thiab PZT8 series nrog daj wafer;
B. Kev faib tawm zaus: tsawg zaus series (2023KHz), nruab nrab zaus series (2528KHz), nruab nrab high zaus series (3360KHz) thiab high zaus series (68-200khz);
C. Fais fab kev faib tawm: 50W (suav nrog 60W), 100W (suav nrog 80W) thiab lwm yam tsis zoo lub zog;
D. Kev faib tawm cov duab: kem puab thiab horn puab;
Daim ntawv thov ntawm ultrasonic transducer nrog txawv piezoceramics
A. Kev sib piv ntawm piezoelectric wafers:
Cov wafer daj yog PZT8 series (qhib raws li lub teb chaws tus qauv, tib yam hauv qab no) siab -cov khoom siv hluav taws xob piezoelectric ceramic, uas muaj qhov zoo ntawm cov nqi qis qis, qhov poob me me ntawm qhov muaj zog thiab zoo thermal stability. Nws yog feem ntau haum rau siab - lub zog ultrasonic emission, xws li ultrasonic vuam thiab siab - fais fab tu.
Dub wafer yog PZT4 series piezoelectric ceramic khoom, nrog siab dielectric tas li, siab electromechanical coupling coefficient thiab lwm yam zoo, feem ntau haum rau nruab nrab hwj chim ultrasonic daim ntaub ntawv, xws li tu los yog transceiver sensors.
B. Kev sib piv ntawm ultrasonic transducer nrog txawv nti:
Piv nrog rau tib lub voj voog tsav tsheb, cov xim daj nti transducer muaj qhov tsis tshua muaj nqi ntawm kev hloov pauv thiab qhov poob me me ntawm qhov muaj zog, yog li nws muaj qis calorific nqi thiab zoo thermal stability. Cov txaws yog ruaj khov rau kev tu lub nra, qhov cuam tshuam loj, yog hom duab plaub tsis tu ncua.
Cov nti dub transducer muaj electro-txheej txheem coefficient sib txuas thiab Curie kub, yog li cov electro-acoustic conversion efficiency siab. Thiab piv nrog lwm cov khoom siv dav dav PZT4 series muaj kev ruaj ntseg dua thiab siab dua kub ua haujlwm. Cov tshuaj tsuag yog tus cwj pwm los ntawm cov kab dej siab, nplua nuj vacuolar xav, tab sis siab rhiab heev rau kev hloov ntawm tu load.
Daim ntawv thov scenario (pom zoo): Siab- zaus (xws li saum toj no 40K) lossis qis- fais fab transducer (qis dua 60W) nrog dub nti transducer, qis- zaus lossis siab{{5} } fais fab transducer nrog daj nti transducer.
