Qhov teeb meem ntawm ultrasonic generator, transducer thiab tshuab raj
Nws yuav tsum hais txog tias lub tshuab hloov ultrasonic nws tus kheej tsis yog lub zog tsim hluav taws xob, nws tsuas yog lub zog hloov kho lub zog. Nws hloov lub zog hluav taws xob rau lub suab hluav taws xob (lub zog siv tshuab). Hauv qab qhov kev xav tias qhov kev tawm tswv yim (tsav lub zog) thiab cov khoom tso tawm (amplifier, ultrasonic pwm) tau zoo sib xws, nws tuaj yeem hloov (tso zis) ntau lub zog.

Cov lus qhia muab piv rau qhov sib txuam ntawm lub tshuab xa mus thiab cov fais fab ultrasonic. Yog tias cov khoom siv tau zoo sib xws tab sis cov lus taw qhia tsis raug zoo, lub tshuab hloov ua kom tsis muaj zog thiab lub vuam tsis muaj zog. Yog hais tias cov zis piv tsis zoo tab sis cov kev sib txuam sib txuam yog qhov zoo, lub tshuab hloov pauv yuav dhau lawm, ua rau nti nti tawg, tawg, tawg ntsia hlau, txhuas tawg lossis hlawv lub raj fais fab ntawm lub thawv hluav taws xob. Piv txwv, zoo li lub tsheb npleem nrawm ntawm lub tsuj roj hauv nruab nrab cov iav, lub cav yuav tsum tau yooj yim ua kom puas.
Qhov sib txuam ntawm lub tshuab hloov tsheb thiab lub zog tsav tsheb thauj khoom mas muaj 4 yam, piv txwv li impedance txuam, zaus txuam nrog, kev ua kom raug hluav taws xob thiab lub zog piv tau raug.
Zaus txuam yog qhov tseem ceeb heev. Qhov no yog ua ntej vim tias lub ultrasonic transducer tsuas tuaj yeem ua haujlwm ntawm nws qhov resonance zaus, yog li lub zog tsav khoom, lub zog, thiab lub vuam tuag (lub taub hau cuab yeej) yuav tsum tau ua haujlwm ntawm txhua zaus.
Lub zog sib txuam thiab impedance txuam tsuas yog xav txog tias ultrasonic vuam system ua haujlwm nyob rau hauv qhov sib txawv, thiab lub nra hloov pauv heev. Yuav tsum muaj hluav taws xob tsim tawm txaus thaum vuam, thiab qhov tsawg kawg nkaus yuav tsum tau tswj thaum tsis muaj load. Txwv tsis pub, raws li tau hais ua ntej lawm, yog tias cov ntsiab lus ntau dhau lawm yam tsis muaj lub nra, tus hloov khoom yuav raug puas ntsoog. Lub hwj chim yuav tsis sawv thaum tag nrho thauj, thiab nws yuav tsis zoo siv yog tias lub vuam tsis muaj zog.
