Kev Taw Qhia Ntawm Cov Khoom Siv Feem Ntau Rau Piezoelectric Transducers

Kev taw qhia txog cov khoom siv feem ntau rau piezoelectric transducers

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.

1. Tus nqi ntawm kev nthuav dav thiab kev cog lus ntawm quartz siv lead ua yog me heev, thiab qhov hluav taws xob ntawm 3000V tsuas yog ua rau deformation hauv qab 0.01um.

2. Cov nyhuv piezoelectric ntawm barium titanate yog 20-30 lub sij hawm loj dua li ntawm quartz siv lead ua, tab sis nws cov efficiency thiab txhua yam muaj zog tsis zoo li quartz siv lead ua.

3. Lead zirconate titanate muaj qhov zoo ntawm ob qho tib si thiab tuaj yeem siv los ua ib qho transducer rau ultrasonic tu, 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.
