Tej teeb meem thiab kev saib xyuas ntawm ultrasonic generator

ib. Ultrasonic siv zog tsis muaj zog

1. siv lub ntsuas ntsuas zaus los ntsuas seb tus tswv zaus puas nyob hauv qhov ntau zaus. Feem ntau, 28K oscillator yog 27-31k, thiab 40K oscillator yog 39-41k. Yog tias qhov sib txawv loj dhau lawm, nws tuaj yeem rov qab tau los ntawm kev hloov kho zaus hloov potentiometer ntawm lub rooj tsavxwm loj.

2. saib qhov tam sim no ntawm ammeter. Yog tias qhov tam sim no me me dhau ntawm qhov ntsuas tam sim no, ua ntej xyuas seb lub vibrator puas puas, xws li vibrator ntog, vibrator nti tawg, bonding kua nplaum tawg, thiab seb cov hlau txuas yog luv luv Circuit Court. Feem ntau, yog tias tam sim no poob me ntsis lossis yuav luag tsis muaj, thiab lub suab zoo li qub, tab sis qhov kev siv ultrasonic poob qis heev, nws yuav zoo li lub vibrator bonding kua nplaum yog tawg. Txoj kev txiav txim yog raws li nram no:; Saib xyuas cov kua nplaum txheej ntawm kev sib txuas ntawm lub vibrator thiab steel phaj. Nyob rau hauv ib txwm muaj xwm txheej, nws yuav tsum yog ib tug du nto. Yog tias muaj qhov tawg me me, nws zoo li cov kua nplaum tau tawg. Lub sijhawm no, lub vibrator yuav tsum tau muab tshem tawm thiab rov ua dua. Yog tias qhov poob tam sim no hnyav heev, feem ntau xyuas seb puas muaj qhov qhib hluav taws xob ntawm cov hlau txuas lossis nti tawg ntawm lub vibrator.

3. feem ntau, qhov ua hauj lwm voltage, tu khoom, dej kub thiab hom kev ntxuav cov kua yuav muaj kev cuam tshuam rau lub ultrasonic siv. Tshwj xeeb tshaj yog nyob rau hauv cov ntaub ntawv ntawm kev ntxhov siab heev, lub ultrasonic yuav tsis muaj zog thiab zoo tom qab kaum vib nas this. Ua tib zoo saib rau txoj kev siv.

b. Muaj ultrasound, tab sis lub zog tsis tuaj yeem hloov kho.

1. xyuas seb lub thyristor puas luv luv. Yog tias muaj, hloov nws. Txwv tsis pub, xyuas cov kauj ruam tom ntej.

2. xyuas seb lub triode T5 puas puas lawm. Yog tias muaj, hloov nws.

c. Tsis muaj ultrasonic, lub hwj chim hloov qhov taw qhia yog nyob rau, thiab kiv cua ua haujlwm ib txwm.

1. tshem tawm cov khoom siv hluav taws xob, tig lub hwj chim, kho lub zog kom siab tshaj plaws, siv lub multimeter AC 1000V iav, thiab ntsuas qhov voltage ntawm qhov tso zis kawg, uas feem ntau yog 1000V. Yog hais tias muaj voltage, lub generator yog OK. Txuas lub tso zis cable.

2. siv DC 1000V iav ntawm multimeter los ntsuas seb puas muaj txog 300V ntawm qhov zoo thiab qhov tsis zoo ntawm qhov tso zis ntawm lub ntsiab capacitor lossis rectifier choj. Yog tias muaj voltage, xyuas cov kauj ruam tom ntej.

d. Tsis muaj ultrasonic, lub hwj chim hloov qhov taw qhia tsis nyob, thiab kiv cua tsis tig.

1. xyuas seb lub hwj huam hloov puas puas lawm. Yog tias muaj, hloov lub hwj chim hloov. Txwv tsis pub, xyuas cov kauj ruam tom ntej.

2. xyuas seb lub kiv cua puas puas lawm. Yog tias muaj, hloov lub kiv cua.

e. Tsis muaj ultrasonic, tsis muaj zaub ntawm lub hwj chim hloov qhov taw qhia, thiab kiv cua ua haujlwm ib txwm.

1. xyuas seb tus choj rectifier puas puas lawm.

2. xyuas seb lub ntsiab capacitor puas puas lawm. Yog tias muaj, hloov lub capacitor.

3. xyuas seb lub raj fais fab puas puas lawm.

Kev saib xyuas tshwj xeeb yuav tsum tau them thaum kho. Lub tshuab yuav tsum muab tso rau hauv qhov chaw qhuav thiab qhov cua. Qhov kev ncua deb ntawm lub nraub qaum ntawm lub tshuab mus rau lub vaj tse yuav tsum siab tshaj 30mm rau cov cua kub dissipation. Thaum muaj teeb meem, hu rau cov neeg ua haujlwm tu lub sijhawm. Tsis txhob qhib lub hau npog kom tsis txhob raug mob
