Abstract: Kev poob teeb liab yog ib qho mob taub hau tshaj plaws rau cov neeg siv ultrasonic flowmeter. Thaum lub cuab yeej tsis tuaj yeem ntes tau ultrasonic echoes, cov nyeem yuav dhia, tsis ruaj khov lossis qhia xoom ntws. Ntau tus neeg siv tam sim ntawd xav tias lub transducer lossis lub meter host yog faulty. Hauv feem ntau ntawm cov xwm txheej hauv daim teb, kev poob teeb liab tshwm sim los ntawm kev teeb tsa, cov yeeb nkab mob, kua lossis cov yam ntxwv ib puag ncig, tsis yog kev puas tsuaj rau kho vajtse. Cov lus qhia daws teeb meem ib kauj ruam zuj zus no pab koj nrhiav tau qhov ua rau thiab rov qab ntsuas dua.
Kev Taw Qhia
Cov ntsuas dej ntws ultrasonic xam qhov ceev ntawm cov dej ntws los ntawm kev xa thiab txais cov suab ultrasonic hla cov yeeb nkab. Lub teeb liab ruaj khov yog lub hauv paus ntawm kev ntsuas qhov tseeb. Yog tias lub ntsuas qhia txog lub teeb liab tsis muaj zog, tsis muaj teeb liab lossis poob lub teeb liab tsis tu ncua thaum cov kua ntws, koj cov ntaub ntawv tsim khoom lossis kev saib xyuas dej yuav tsis ntseeg tau. Tsab xov xwm no npog cov laj thawj ib txwm muaj thiab kev kuaj xyuas hauv qhov chaw rau ob qho tib si.Cov yam ntxwv ntawm clamp-on portable ultrasonic flowmetersthiab cov qauv ultrasonic inline ruaj khov.
1. Teeb meem ntawm phab ntsa yeeb nkab thiab cov khoom siv yeeb nkab (qhov laj thawj tseem ceeb rau hom clamp-on)
Lub teeb ultrasonic yuav tsum hla dhau phab ntsa yeeb nkab. Cov yeeb nkab tsis zoo yuav thaiv lossis ua rau lub suab tsis muaj zog.
- Kev xeb ntawm phab ntsa yeeb nkab, kev tawg lossis txheej xebCov xeb tuab, cov nplai lime lossis cov cement txheej rau ntawm phab ntsa sab hauv/sab nraud ntawm cov yeeb nkab nqus tau lub zog ultrasonic. Lub transducer tsis tuaj yeem xa thiab txais cov cim kom raug.
- Cov khoom siv yeeb nkab tsis sib xwsCov yas, hlau, hlau ductile, hlau stainless ua haujlwm zoo. Qee cov kav dej uas muaj ntaub (roj hmab hauv, epoxy hauv) yuav ua rau lub suab ultrasound tsis zoo thiab ua rau lub teeb liab poob.
- Cov yeeb nkab sab nraud tsis sib npaugCov qhov me me, khawb, xim qub lossis qhov chaw ntxhib ntawm qhov chaw teeb tsa transducer. Cov roj sib txuas tsis tuaj yeem sau cov qhov sib txawv tag nrho.
Kev Ua: Ntxuav cov kav dej kom huv si ntawm qhov chaw teeb tsa sensor; tshem tawm cov xeb xoob thiab cov xim tuab. Yog tias cov ntaub hauv kav dej tuab dhau, rov ntsuam xyuas qhov kev xaiv ntawm lub ntsuas.
2. Cov xwm txheej kua dej hauv cov kav dej
- Cov pa npuas / cov pa hauv cov kuaTxawm tias cov npuas me me kuj tseem ua rau cov teeb ultrasonic tawg. Qhov no yog ib qho uas tshwm sim ntau rau cov dej huv uas muaj cua nkag, tshwj xeeb tshaj yog rau ntawm cov kav dej siab. Cov qhov cua loj dua tuaj yeem txiav tawm tag nrho cov teeb liab.
Lub Tswv Yim: Nruab cov qhov tso cua tawm. Tsiv cov transducers mus rau qhov seem yeeb nkab qis dua uas cov yeeb nkab tseem puv tag.
- Cov khoom ruaj khov siabCov av nkos hnyav, xuab zeb lossis cov khoom me me yuav ua rau cov nthwv dej suab tawg. Rau kev siv dej huv qhov kev pheej hmoo no tsawg, tab sis cov dej uas muaj cov av nkos ntau tseem tuaj yeem ua rau lub teeb liab poob.
- Qhov sib txawv ntawm qhov kub thiab txias heev ntawm cov yeeb nkab thiab cov kua dej: Qhov sib txawv ntawm qhov kub thiab txias loj heev yuav ua rau lub suab xa tsis tau zoo.
3. Kev teeb tsa transducer & teeb meem txuas
Qhov no yog qhov # 1 qhov txhaum rau cov ntsuas dej ultrasonic portable.
- Cov roj sib txuas tsis txaus lossis qhuav: Cov roj xa cov ultrasound ntawm lub transducer thiab yeeb nkab. Yog tias cov roj nyias dhau, raug nias tawm lossis tawv, cov teeb liab poob.
- Qhov nrug ntawm lub transducer tsis yog: Tus tswv tsev xam qhov nrug ntawm lub sensor raws li qhov OD ntawm cov yeeb nkab thiab qhov tuab ntawm phab ntsa. Yog tias koj teeb tsa cov probes nrog qhov nrug tsis yog, lub teeb ultrasonic yuav tsis pom lub transducer txais.
- Kev clamping xoob: Cov transducers tsis raug nias kom nruj rau ntawm qhov chaw ntawm cov yeeb nkab. Kev co tuaj yeem maj mam cais cov probes ntawm phab ntsa yeeb nkab.
- Cov transducers tau teeb tsa rov qab los yog tsis sib xws.
Tshawb xyuas sai: Rov siv cov gel tshiab rau kev sib txuas, zawm cov clamps, thiab xyuas ob zaug seb qhov nrug ntawm lub sensor nyob rau ntawm daim ntawv qhia zaub mov 'meter'.
4. Kev teeb tsa tsis raug ntawm lub ntsuas dej ntws
Cov kev teeb tsa yeeb nkab tsis raug yuav ua rau kev ntes cov teeb liab tsis ua haujlwm.
- Txoj kab uas hla sab nraud ntawm cov yeeb nkab, qhov tuab ntawm phab ntsa lossis cov khoom siv yeeb nkab tsis raug. Lub ntsuas yuav xam txoj kev suab tsis raug.
- Qhov teeb tsa qhov ceev ntawm lub suab tsis raug rau cov kua.
- Kev xaiv tsis raug ntawm tus qauv transducer.
Lub Tswv Yim: Rov sau cov qauv yeeb nkab kom zoo zoo. Paub meej tias OD thiab phab ntsa tuab los ntawm kev ntsuas lub cev, tsis yog tsuas yog cov ntaub ntawv kos duab xwb.
5. Kev cuam tshuam sab nraud thiab ib puag ncig
- Kev cuam tshuam hluav taws xob muaj zog: Cov tsav tsheb hloov pauv zaus, cov cav loj, cov khoom siv vuam nyob ze. EMI cuam tshuam cov teeb liab ultrasonic tsis muaj zog.
- Kev co ntawm cov yeeb nkab hnyav: Kev co muaj zog tas mus li ua rau cov transducers xoob thiab tsim kev sib cuag tsis ruaj khov.
- Qhov kub thiab txias heev tshaj qhov qhia ntawm transducer.
6. Kev puas tsuaj ntawm cov khoom siv (tsis tshua muaj)
Yog tias tag nrho cov kev kuaj xyuas saum toj no dhau thiab lub teeb liab tseem ploj, xav txog qhov teeb meem kho vajtse:
- Cov khoom siv lead ua transducer puas lawm (kev khob, kev cuam tshuam, kev puas tsuaj rau lub sijhawm ntev)
- Cov xov hlau transducer tawg, cov xov hlau sab hauv tawg
- Qhov tsis zoo ntawm lub rooj tsavxwm hluav taws xob tseem ceeb ntawm lub ntsuas dej ntws
Cov lus qhia txog kev kuaj mob: Hloov cov transducers mus rau ib lub raj kuaj uas paub zoo. Yog tias tseem tsis muaj teeb liab, cov transducer lossis cable tej zaum yuav puas lawm.
Daim ntawv teev cov txheej txheem ua ntej hu rau kev pab txhawb nqa kev siv tshuab
Sau cov ntaub ntawv no kom txhawb nqa tau sai dua:
- Tus qauv ntsuas dej ntws thiab hom transducer
- Yeeb Nkab OD, phab ntsa tuab, cov khoom siv yeeb nkab thiab txheej txheej
- Nruab nrab, kub thiab seb puas muaj pa npuas
- Tus nqi zog teeb liab qhia rau ntawm lub vijtsam ntsuas
- Cov duab ntawm kev teeb tsa transducer thiab cov yeeb nkab nto
Cov lus qhia tiv thaiv
- Xaiv qhov loj ntawm lub transducer kom haum rau koj lub yeeb nkab txoj kab uas hla.
- Ib txwm ntxuav cov yeeb nkab kom huv si thiab siv cov roj nplaum txaus thaum lub sijhawm teeb tsa.
- Tsis txhob txhim kho cov transducers rau ntawm cov yeeb nkab siab uas muaj cua sib sau ua ke.
- Khaws cov transducers kom deb ntawm cov motors, inverters thiab kev co hnyav.
- Rov xyuas dua cov kev teeb tsa ntawm cov yeeb nkab tom qab txhua zaus teeb tsa lub 'meter' uas nqa tau.
