Kev siv cov kav dej yog ib qho tseem ceeb uas yuav tsum xav txog thaum xaiv ib lub tsevclamp-on ultrasonic flow meterTxawm hais tias cov transducers tau teeb tsa rau sab nraud ntawm lub yeeb nkab, lub teeb liab ultrasonic yuav tsum hla dhau phab ntsa yeeb nkab thiab, feem ntau, sab hauv ua ntej ncav cuag cov kua.
Yog li ntawd, hom thiab tuab ntawm cov yeeb nkab sab hauv tuaj yeem muaj kev cuam tshuam loj raulub zog ntawm lub teeb liab, kev xa xov acoustic, qhov chaw ntawm transducer, thiab kev ruaj khov ntawm kev ntsuas.
1. Lub Teeb Liab Ultrasonic Mus Los Ntawm Cov Yeeb Nkab Uas Muaj Kab Li Cas?
Rau ib qho clamp-on ultrasonic flow meter, lub teeb liab ultrasonic ua raws li txoj kev zoo sib xws:
Transducer → Yeeb Nkab Phab Ntsa → Yeeb Nkab Sab Hauv → Kua → Yeeb Nkab Sab Hauv → Yeeb Nkab Phab Ntsa → Transducer
Tsis zoo li lub ntsuas dej ntws, cov transducers tsis kov cov kua ncaj qha.
Lub teeb liab ultrasonic yuav tsum taug kev hla ntau yam khoom sib txawv ua ntej nws mus txog cov kua. Txhua yam khoom muaj cov yam ntxwv suab sib txawv, yog li lub teeb liab yuav muaj kev cuam tshuam, kev cuam tshuam, thiab kev txo qis ntawm qhov sib txuas ntawm cov khoom.
Qhov no yog vim li cas cov yeeb nkab hauv tsev yuav tsum tau xav txog thaum lub sijhawm teeb tsa ultrasonic flow meter.
2. Vim li cas cov khoom siv hauv pem teb thiaj tseem ceeb?
Cov ntaub ntawv sib txawv muaj cov yam ntxwv sib txawvacoustic impedance thiab suab velocity.
Cov ntaub ntawv siv rau hauv cov yeeb nkab feem ntau muaj xws li:
- PTFE
- Roj Hmab
- Roj hmab tawv
- Cov tshuaj cement
- Epoxy
- Yas
- Lwm cov txheej tiv thaiv
Thaum lub zog ultrasonic mus los ntawm ib yam khoom mus rau lwm yam, ib feem ntawm nws lub zog yuav raug cuam tshuam ntawm qhov interface.
Piv txwv li:
Yeeb Nkab Phab Ntsa → Sab Hauv → Kua
Ntawm txhua qhov interface, qhov sib txawv ntawm cov khoom acoustic tuaj yeem cuam tshuam rau ntau npaum li cas lub zog ultrasonic nkag mus rau hauv cov khoom tom ntej.
Yog tias qhov sib txawv ntawm lub suab yog qhov tseem ceeb, ntau lub zog yuav raug cuam tshuam thiab tsawg lub zog yuav mus txog lub transducer txais.
Qhov no tuaj yeem ua rau:
Lub zog teeb liab qis dua thiab kev ntsuas suab nyuaj dua.
3. Vim li cas qhov tuab ntawm daim ntaub thiaj tseem ceeb?
Lub thickness ntawm daim ntaub kuj tseem ceeb heev.
Ib daim ntaub nyias nyias yuav muaj qhov cuam tshuam tsawg, thaum daim ntaub tuab tuaj yeem ua rau txoj kev acoustic ntev dua los ntawm cov ntaub ntaub.
Thaum lub teeb liab ultrasonic taug kev hla lub txheej, ib feem ntawm nws lub zog tuaj yeem raug txo qis.
Yog li ntawd, qhov xwm txheej ntsuas yog cuam tshuam los ntawm:
Cov Khoom Siv Sab Hauv + Qhov Thickness Sab Hauv + Cov Khoom Siv Acoustic
Vim li no, ob lub kav dej uas muaj tib lub cheeb tsam thiab tib yam khoom siv sab nraud yuav ua txawv yog tias lawv cov ntaub sab hauv sib txawv.
Piv txwv li:
Cov yeeb nkab carbon steel tsis muaj daim ntaub
thiab
Cov yeeb nkab carbon steel nrog lub hauv roj hmab tuab
tej zaum yuav muaj cov yam ntxwv sib txawv ntawm kev xa xov ultrasonic.
4. Vim li cas cov roj hmab thiab cov yas thiaj li nyuaj rau kev siv?
Qee cov ntaub mos mos lossis cov ntaub mos mos uas muaj suab qis tuaj yeem ua rau kev ntsuas ultrasonic clamp-on nyuaj dua.
Piv txwv suav nrog qee yam:
- Cov ntaub roj hmab
- PTFE linings
- Cov yas sab hauv
Lub nthwv dej ultrasonic yuav muaj kev cuam tshuam ntau dua lossis kev cuam tshuam thaum hla dhau cov ntaub ntawv no.
Qhov no tuaj yeem ua rau:
- Lub zog teeb liab txo qis
- Muaj teeb meem ntau ntxiv rau kev nrhiav pom cov teeb liab
- Ib qho ntau yam ntawm qhov chaw sib txawv ntawm cov transducer uas tsim nyog
- Kev nkag siab ntau dua rau cov xwm txheej ntawm kev teeb tsa
Qhov no tsis tau txhais hais tias cov kav dej uas muaj kab tsis tuaj yeem ntsuas tau.
Tiam sis, lub ntsuas dej yuav tsum tau xaiv thiab teeb tsa kom raug raws li cov yeeb nkab thiab cov ntaub ntawv tiag tiag.
5. Cov Yeeb Nkab Sab Hauv Cuam Tshuam Li Cas Rau Qhov Sib Nrug ntawm Transducer?
Rau clamp-on ultrasonic flow meters, qhov transducer spacing feem ntau yog xam raws li ntau yam kev ntsuas, suav nrog:
- Txoj kab uas hla ntawm cov yeeb nkab
- Cov yeeb nkab phab ntsa tuab
- Cov khoom siv yeeb nkab
- Cov khoom siv hauv pem teb
- Qhov tuab ntawm daim ntaub
- Hom kua
- Kub ntawm cov kua
- Ultrasonic velocity los ntawm cov ntaub ntawv sib txawv
Yog li ntawd, yog tias cov ntaub ntawv hauv daim ntaub uas nkag mus rau hauv lub ntsuas dej tsis raug, qhov chaw ntawm lub transducer uas tau xam kuj yuav tsis raug.
Piv txwv li, yog tias cov yeeb nkab tiag tiag muaj cov roj hmab 5 hli sab hauv tab sis cov cuab yeej tau teeb tsa ua cov yeeb nkab hlau tsis muaj sab hauv, txoj kev acoustic uas tau xam yuav tsis phim qhov tseeb ntawm cov qauv yeeb nkab tiag tiag.
Qhov no tuaj yeem ua rau kev nrhiav tau cov teeb liab nyuaj dua thiab yuav cuam tshuam rau kev ntsuas kev ua tau zoo.
6. Lub Flow Meter puas muaj lub teeb liab muaj zog ntawm cov yeeb nkab uas muaj kab?
Yog.
Ib lub yeeb nkab uas muaj kab tsis tau txhais hais tias lub teeb liab ultrasonic yuav tsis muaj zog.
Lub zog ntawm lub teeb liab tiag tiag nyob ntawm seb muaj pes tsawg lub teeb liab sib xyaw ua ke:
Cov Khoom Siv Yeeb Nkab + Phab Ntsa Thickness + Sab Hauv + Kua + Transducer + Kev Teeb Tsa
Ib qho kev teeb tsa zoo tsim rau ntawm cov yeeb nkab uas muaj kab tseem tuaj yeem muab cov teeb liab ultrasonic ruaj khov thiab muaj zog.
Yog li ntawd, qhov muaj ib daim ntaub sab hauv yuav tsum tsis txhob raug suav hais tias yog qhov qhia tau tias kev ntsuas ultrasonic clamp-on tsis tsim nyog.
7. Cov npuas cua ua rau qhov teeb meem hnyav dua li cas?
Cov kav dej uas muaj kab kuj tseem tuaj yeem nthuav tawm lwm qhov teeb meem: cua sib sau ua ke.
Yog tias cov yeeb nkab tsis puv tag, lossis yog tias muaj cov pa npuas nyob hauv cov kua, lub teeb liab ultrasonic tuaj yeem raug txo qis lossis tawg.
Qhov xwm txheej sib xyaw ua ke ntawm:
Sab hauv tuab + Cov pa npuas + Kev sib txuas tsis zoo
tuaj yeem ua rau kev xa cov teeb liab ultrasonic nyuaj tshwj xeeb.
Yog li ntawd, qhov chaw teeb tsa yuav tsum tau xaiv zoo tshaj plaws rau ntawm ib qho chaw.seem yeeb nkab puv nkaus, deb ntawm qhov chaw uas cua tuaj yeem sib sau ua ke.
8. Cov Kws Ua Haujlwm Yuav Tsum Soj Ntsuam Cov Yeeb Nkab Uas Muaj Kab Li Cas?
Ua ntej yuav txhim kho lub clamp-on ultrasonic flow meter, nws raug pom zoo kom sau cov ntaub ntawv hauv qab no:
- Lub raj sab nraud
- Cov yeeb nkab phab ntsa tuab
- Cov khoom siv yeeb nkab
- Cov khoom siv hauv pem teb
- Qhov tuab ntawm daim ntaub
- Hom kua
- Kub ntawm cov kua
- Qhov ceev ntawm kev ntws uas xav tau
- Cov yeeb nkab mob
- Muaj cov yeeb nkab ntev
Cov ntaub ntawv no tso cai rau lub ntsuas dej kom txiav txim siab qhov kev teeb tsa suab thiab qhov chaw transducer kom haum dua.
Rau cov ntawv thov nyuaj, kev sim tiag tiag ntawm qhov chaw kuj tseem tuaj yeem pab tau ua ntej kev teeb tsa zaum kawg.
9. Cov tsos mob ntawm qhov teeb meem ntsig txog daim ntaub yog dab tsi?
Qhov teeb meem acoustic cuam tshuam nrog lining yuav zoo li:
- Lub zog teeb liab qis
- Lub zog teeb liab tsis ruaj khov
- Qhov nyuaj rau tau txais lub teeb liab ultrasonic
- Kev nyeem cov dej ntws tsis raug lossis tsis ruaj khov
- Kev poob ntawm lub teeb liab ntau zaus
- Muaj zog rhiab heev rau qhov chaw transducer
Txawm li cas los xij, cov tsos mob no tsis tas txhais tau tias lub txheej nws tus kheej yog tib qho ua rau.
Cov tsos mob zoo sib xws kuj tuaj yeem tshwm sim los ntawm:
- Kev sib txuas ntawm transducer tsis zoo
- Qhov chaw transducer tsis raug
- Cov yeeb nkab phab ntsa tuab dhau heev
- Cov npuas cua
- Cov kev teeb tsa yeeb nkab tsis raug
- Kev xeb ntawm cov yeeb nkab
- Kev co ntawm cov yeeb nkab
Yog li ntawd, kev daws teeb meem yuav tsum xav txog tag nrho txoj kev acoustic es tsis txhob tsom mus rau ntawm daim ntaub ib leeg xwb.
Cov yeeb nkab hauv cov kav dej cuam tshuam rau kev ntsuas qhov ntws ntawm ultrasonic clamp vim tias lub teeb liab ultrasonic yuav tsum dhau los ntawmphab ntsa yeeb nkab thiab sab hauv ua ntej nkag mus rau hauv cov kua.
Cov khoom siv hauv ob sab hauv thiab qhov tuab tuaj yeem cuam tshuam rau kev xa xov acoustic, kev txo qis ntawm lub teeb liab, kev cuam tshuam, thiab qhov chaw transducer uas xav tau.
Cov yam tseem ceeb tuaj yeem sau ua ke raws li:
Cov Khoom Siv Yeeb Nkab + Phab Ntsa Thickness + Cov Khoom Siv Sab Hauv + Sab Hauv Thickness + Cov Khoom Siv Ua Kua → Kev Kis Acoustic → Kev Zoo ntawm Lub Teeb Liab → Kev Ntsuas Kev Ruaj Ntseg
Yog li ntawd, thaum xaiv thiab txhim kho lub clamp-on ultrasonic flow meter, cov yeeb nkab hauv kab yuav tsum tau kho ib txwm ua ib feem tseem ceeb ntawm txoj kev ntsuas acoustic.
Ib lub yeeb nkab uas muaj kab tsis tas yuav tiv thaiv kev ntsuas ultrasonic, tab sisCov khoom siv sab hauv thiab qhov tuab yuav tsum tau xav txog kom raug thaum lub sijhawm xaiv cov ntsuas dej ntws, kev teeb tsa cov txheej txheem, thiab kev teeb tsa transducer.
