20Khz Kev Ua Haujlwm Siab Ultrasonic Vibrator

Taw qhia:

Cov ultrasonic vibrator yog kev sib txuas ntawm cov ultrasonic transducer thiab lub tshuab raj, thiab yog ib qho ntawm cov khoom tseem ceeb ntawm cov khoom siv ultrasonic vuam.

Kev Qhia Txog Kev Kawm:

Qauv 5020-4Z

Zaus20 Khz

Altrasonic tuaj yeem kho lub ultrasonic vibrator rau koj daim ntawv thov.

Ultrasonic Vibrator Nta:

1. Ultrasonic vibrator transducer khoom tsos zoo li zoo huv si, tsis muaj xeb, tsis muaj qhov cuam tshuam kev nyuab siab thiab kos

2. Lub tshuab hloov pauv muaj qhov ua kom loj dua thiab muaj qhov zoo dua.

3. Muaj kev ua tau zoo

High mechanical Q tus nqi, hloov dua siab tshiab ua haujlwm tau zoo thiab zoo heev

4. Transducer kuj tiv taus tshav kub

Piezoelectric ceramic khoom muaj cov cua kub zoo, tuaj yeem nthuav dav rau kev ua haujlwm kub, thiab muaj tus nqi Q siab, me me resonance impedance, thiab tsis muaj cua sov tiam.

Txheeb xyuas qhov Zoo ntawm Ultrasonic Vibrator ：

Lub impedance analyzer tuaj yeem siv los ntsuas cov kev ua haujlwm ntawm ntau yam khoom siv xws li piezoelectric ceramic nplooj ntawv, piezoelectric transducers, thiab tag nrho lub tshuab kev co (transducers ntxiv rau tshuab raj, pwm). Tus ultrasonic ntaus ntawv tau soj ntsuam los ntawm ib tug impedance analyzer, thiab tus ultrasonic vibrator tuaj yeem sib txawv. Cov tsis tseem ceeb tseem ceeb muaj raws li hauv qab no:

1. Fs: Cov khoom siv rov ua haujlwm zaus, piv txwv li qhov khiav hauj lwm ntawm lub tshuab kev co, yuav tsum yog ze rau cov nqi tsim nyog hauv qhov tsim thiab yuav tsum sib phim nrog lub zog ua haujlwm kis. Qhov siab dua qhov resonance zaus xwm yeem ntawm ultrasonic vibrator, zoo dua.

2.R1: Dynamic tsis kam, qhov tsis kam ntawm series ceg ntawm piezoelectric ultrasonic vibrator yog me me li sai tau nyob rau hauv tib qho kev txhawb nqa. Txog kev tu ultrasonic vibrators, feem ntau yog nruab nrab ntawm 5 Ω thiab 20 Ω. Yog tias nws loj dhau, lub ultrasonic vibrator lossis kev co lub zog yuav muaj teeb meem, xws li lub xov hluav taws xob tsis sib xws lossis cov hloov hluav taws xob tsawg, thiab lub neej luv ntawm lub ultrasonic vibrator.

3.Qm: yam tsis zoo rau txhua yam, txiav txim siab los ntawm kev coj ua nkhaus txoj kev, Qm=Fs / (F2-F1). Rau kev ntxuav tu ultrasonic vibrator, qhov siab dua Qm tus nqi, zoo dua. Feem ntau hais lus, Qm ntawm ultrasonic vibrator yuav tsum tau muab ntxuav. Nruab nrab ntawm 500 thiab 1000, yog tias nws qis dhau, ultrasonic tshee yog qhov ua tsis tau zoo. Yog tias nws dhau qhov siab dhau, lub zog siv hluav taws xob tsis tuaj yeem sib phim.

4. Fp: resonance zaus, resonant zaus ntawm cov ceg thaum uas tig mus ntawm lub piezoelectric ultrasonic vibrator. Ntawm qhov zaus no, lub impedance Zmax ntawm lub piezoelectric ultrasonic vibrator yog qhov loj tshaj plaws. Yog tias qhov rov qab tiv thaiv tsis haum Zmax tsawg, lub ultrasonic vibrator muaj teeb meem.

Nco tseg:

Lub ultrasonic vibrator yuav tsum muab tso rau hauv qhov chaw qhuav kom tiv thaiv lub ultrasonic vibrator tsis txhob ntub thiab cuam tshuam rau kev ua haujlwm zoo li qub. Ultrasonic vibrators feem ntau yog ua los ntawm titanium alloy.
