Kev soj ntsuam ntxaws ntxaws ntawm piezoelectric siv lead ua haujlwm ntawm piezoelectric transducer
Qhov zoo tshaj plaws thiab txhim khu kev qha piezoelectric siv lead ua yog ib qho cuab yeej uas paub txog kev sib hloov ntawm lub zog hluav taws xob thiab lub zog suab los ntawm cov nyhuv piezoelectric, uas yog hu ua piezoelectric transducer. Cov nyhuv piezoelectric hloov cov teeb liab hluav taws xob rau hauv kev vibrations. Hom transducer no muaj kev ua haujlwm siab electro-acoustic conversion efficiency, pheej yig raw khoom, yooj yim ntau lawm, thiab tsis yooj yim rau hnub nyoog. Cov khoom siv feem ntau yog quartz siv lead ua, barium titanate thiab lead zirconate titanate. Kev nthuav dav thiab kev cog lus ntawm quartz siv lead ua yog me me, thiab qhov hluav taws xob ntawm 3000V tsuas yog ...
Piezoelectric transducer yog hais txog ib qho transducer ua los ntawm cov nyhuv piezoelectric rau pem hauv ntej thiab thim rov qab ntawm cov ntaub ntawv piezoelectric. Raws li lub npe implies, lub transducer yog hais txog ib tug ntaus ntawv uas yuav ua tau lub zog hloov dua siab tshiab. Feem ntau qhov peb hu ua electroacoustic transducer, lub transducer uas tuaj yeem tawm suab tsis tau hu ua transmitter; lub transducer uas tau txais suab tsis yog hu ua receiver. Piv txwv li, piezoelectric buzzer yog ib qho hluav taws xob-acoustic transducer, thiab feem ntau tuaj yeem siv ua lub tswb.
Piezoelectric siv lead ua
Cov cuab yeej paub tab thiab txhim khu kev qha tshaj plaws yog cov nyhuv piezoelectric uas paub txog kev sib hloov ntawm lub zog hluav taws xob thiab lub zog suab, uas yog hu ua piezoelectric transducer.
Cov nyhuv piezoelectric hloov cov teeb liab hluav taws xob rau hauv kev vibrations. Hom transducer no muaj kev ua haujlwm siab electro-acoustic conversion efficiency, pheej yig raw khoom, yooj yim ntau lawm, thiab tsis yooj yim rau hnub nyoog.
Cov khoom siv feem ntau yog quartz siv lead ua, barium titanate thiab lead zirconate titanate.
Tus nqi ntawm kev nthuav dav thiab kev cog lus ntawm quartz siv lead ua yog me me, thiab qhov hluav taws xob ntawm 3000V tsuas yog ua rau deformation hauv qab 0.01um.
Cov nyhuv piezoelectric ntawm barium titanate yog 20-30 npaug ntau dua li ntawm quartz siv lead ua, tab sis nws cov kev ua tau zoo thiab lub zog txhua yam tsis zoo li quartz siv lead ua.
Lead zirconate titanate muaj qhov zoo ntawm ob qho tib si thiab tuaj yeem siv los ua cov khoom siv hluav taws xob rau kev tu ultrasonic, tsis pom kev thiab tsis muaj zog ultrasonic ua.
Piezoelectric transducers yog dav siv. Raws li kev lag luam uas lawv tau siv rau, lawv tau muab faib ua kev lag luam, kev ua liaj ua teb, kev thauj mus los, lub neej, kev kho mob thiab kev ua tub rog.
Raws li kev paub txog kev ua haujlwm, nws tau muab faib ua ultrasonic ua, ntxuav ultrasonic, kuaj xyuas ultrasonic thiab ultrasonic atomization.
