Kev ceev faj rau kev siv ultrasonic transducer
Cov kev txiav txim siab tseem ceeb thaum siv ultrasonic transducer yog qhov sib txuam nrog kev tawm tswv yim thiab cov zis xaus, tom qab ntawd kev teeb tsa kho tshuab thiab txuam qhov ntev. Qhov zaus ntawm qhov hloov pauv yog qhov yooj yim. Qhov zaus yog hais txog qhov zaus ntsuas los ntawm cov kab sib kis tau siv nrog txoj kev ntsuas hluav taws xob (ua haujlwm) lub tshuab hluav taws xob, millivoltmeter, oscilloscope, thiab lwm yam, lossis cov zaus ntsuas nrog cov ntsuas zoo xws li lub network impedance analyzer. Feem ntau hu ua teeb liab me me zaus. Tus neeg siv khoom txuas rau ultrasonic transducer mus rau lub zog tsav hluav taws xob los ntawm kev xaib, thiab qhov tseeb ua haujlwm raug ntsuas thaum tsis muaj lossis thauj khoom tom qab fais fab tuag. Vim tias qhov ntsuas hluav taws xob ntawm cov neeg siv khoom sib txawv, qhov ntau zaus ntawm cov tshuab hluav taws xob ultrasonic sib txawv hauv cov khoom siv tsav sib txawv muaj qhov sib txawv, thiab cov zaus siv tsis tau los ua lub hauv paus rau kev sib tham.
1. Cov teeb meem uas yooj yim tshwm sim thaum siv ultrasonic transducers
Cov teeb meem tshwm sim thaum siv yog nti tawg, tsis muaj zog, ntau dhau, ua hluav taws xob electrode, hluav taws xob nti tawg, hluav taws xob tsim hluav taws xob, hluav taws xob tawg, thiab xaim pov tseg.
Cov laj thawj ntawm cov teeb meem no tuaj yeem muab faib ua peb yam. Ib qho yog qhov teeb meem nrog cov qhua tuaj noj mov' s tsav fais fab mov lossis pwm thiab sib dhos. Qhov thib ob yog tias muaj teeb meem nrog peb lub tshuab hloov pauv thiab tshuab raj. Qhov thib peb yog tias tsis muaj teeb meem nrog cov khoom ntawm ob tog, tab sis lawv tsis sib phim.
Thawj qhov xwm txheej: muaj teeb meem nrog tus neeg siv' s tsav lub zog lossis pwm
Case 2: Muaj teeb meem nrog peb lub ultrasonic transducer thiab horn
Qhov xwm txheej thib peb: Tsis muaj teebmeem nrog cov khoom lag luam ntawm ob tog, tab sis lawv tsis sib phim.
2. Kev ceev faj rau kev sib dhos ntawm txhua ntu ntawm ultrasonic transducer
Qhov tseem ceeb ntawm ultrasonic kev co tshuab, xws li hloov tsheb, tshuab raj, thiab taub hau ntawm cov cuab yeej, tau txuas nrog hauv nruab nrab ntsaws.
1. Txheeb xyuas tias qhov chaw tiv tauj yuav tsum du thiab tsis muaj nti. Yog tias muaj nti, maj mam txhuam nrog metallographic sandpaper saum toj xoom. Nws yog qhov tsim nyog yuav tsum tau ua kom qhov khoob qhov tsis xws luag txhawm rau txhawm rau kom tsis txhob rhuav tshem lub tiaj ntawm kev tiv tauj.
2. Siv lub cev tsis huv thiab tsis xeb kev tu tus kheej kom huv cov screws, ntsia hlau qhov thiab chaw kov.
3. Ua kom huv si lub screws, ntsia hlau qhov thiab chaw kov.
4. Txhua qhov txuas rau cov ntsia hlau yuav tsum muab txiav kom mus rau qhov chaw hu.
5. Muab cov txheej roj nyias nyias roj ntawm butter lossis roj av los tso rau saum qhov chaw sib chwv ua ntej zawm. Ceev faj tsis txhob thov nws rau cov txuas screws thiab ntsia hlau qhov.
6. Ua kom nruj ob ntu kom zoo. Tswj qhov tsim nyog zawm lub zog kom haum raws li qhov tshwj xeeb ntawm kev sib txuas ntawm cov ntsia hlau. Thaum ua tau, nws yuav tsum ua kom nruj.
7. Yog tias koj daws lub ntsej muag sib koom ua ke dua, koj yuav tsum tsis txhob pom muaj nti.
8. Lub cev kev co muaj qhov ua kom dav dav thaum kov ntawm tes, tsis muaj suab nrov txawv, thiab tsis muaj cua sov hauv zos.
9. Tom qab ua haujlwm rau ib lub sijhawm, qhov sib koom ua ke ntawm lub ntsej muag yuav tsum tsis txhob oxidized lossis ablated tom qab rov qhib dua, txwv tsis pub nws txhais tau hais tias kev sib cuag ntawm no tsis zoo thiab lub zog ultrasonic ploj ntawm no tiag.
3. Kev ua haujlwm kub ntawm lub ultrasonic transducer
Ultrasonic transducers yuav tsim kom muaj cua sov thaum siv, uas feem ntau yog ua los ntawm peb yam. Ib qho yog cov neeg ua haujlwm yuav tsum tau txais welded yuav ua kom sov lossis cov khoom siv ua tiav los ntawm ultrasonic yuav ua kom sov, lossis cov pwm (lub cuab yeej lub taub hau) thiab lub tshuab raj yuav ua kom sov ntev, thiab cov cua sov no yuav hloov mus rau qhov hloov pauv. Qhov thib ob yog lub hwj chim poob ntawm lub transducer nws tus kheej. Txij li 100% kev hloov ua lub zog tsis tuaj yeem ua tiav, ib feem ntawm lub zog poob yuav tsum hloov mus rau hauv tshav kub. Qhov kub nce siab yuav ua rau qhov ciaj ciam ntawm ultrasonic transducer hloov, uas yuav maj mam xaiv los ntawm lub xeev zoo tshaj plaws. Dab tsi yog qhov hnyav tshaj yog tias qhov kub nce siab yuav ua rau muaj qhov tsis zoo ntawm piezoelectric ceramic wafer kev ua tau zoo. Qhov no, nyeg, ua rau ultrasonic transducer ua haujlwm tsis zoo thiab ua kom kub sai dua, uas yog lub voj vaim dua. Yog li no, peb yuav tsum muab cov kev mob txias zoo rau lub tshuab ultrasonic, uas feem ntau ua kom txias ntawm chav sov; yog tias tsim nyog, cov cua txias kuj tseem siv tau. Nyob rau hauv cov xwm txheej ib txwm, qhov kub nce los ntawm ob lub ntsiab lus no kuj yog qhov qub, thiab nyob hauv qhov txias txias ib txwm, yuav tsis muaj teeb meem loj.
