1. Rau TF1100 clamp ntawm cov transducers ntws, muab ib lub hlaws ntawm couplant, kwv yees li 0.05 nti [1.2mm] tuab, ntawm lub ntsej muag tiaj tus ntawm lub transducer. Feem ntau, cov roj silicone yog siv uaib qho acoustic couplant, tab sis txhua yam roj zoo li cov khoom uas tau ntsuas tsis "ntws" ntawmqhov kub uas cov yeeb nkab yuav ua haujlwm yuav txais tau.
2. Muab lub transducer saum toj tso rau hauv qhov chaw thiab ruaj ntseg nrog ib txoj hlua khi. Cov hlua khi yuav tsum tau muab tso rau hauv qhov groove ntawm qhov kawg ntawm lub transducer. Muaj ib lub ntsia hlau los pab tuav lub transducer rau ntawm txoj hlua. Xyuas kom tseeb tias lub transducer lo rau ntawm lub yeeb nkab - kho raws li qhov tsim nyog. Nruj lub transducer txoj hlua kom ruaj ntseg.
3. Muab lub transducer downstream tso rau ntawm lub yeeb nkab ntawm qhov sib nrug ntawm lub transducer uas tau xam lawm. Saib Daim Duab 2.3. Siv tes nias kom ruaj khov, maj mam txav lub transducer mus rau thiab tawm ntawm lub transducer upstream thaum saib lub zog ntawm lub teeb liab. Tuav lub transducer rau ntawm qhov chaw uas pom lub zog ntawm lub teeb liab siab tshaj plaws. Lub zog ntawm lub teeb liab (Menu 90) ntawm 60 thiab 95 yog qhov siv tau.
4. Yog tias tom qab kho cov transducers lub zog teeb liab (Cov ntawv qhia zaub mov 90) tsis nce mus txog 60, ces yuav tsum xaiv lwm txoj kev teeb tsa transducer. Yog tias txoj kev teeb tsa yog W-hom, ces rov teeb tsa TF1100 rau V-hom, pib dua TF1100, txav lub transducer downstream mus rau qhov chaw tshiab thiab rov ua kauj ruam 3.
V-Mount yog txoj kev teeb tsa STD, nws yooj yim thiab raug, Hom kev cuam tshuam (cov transducers qhov ncauj rau ntawm ib sab ntawm cov yeeb nkab) ntawm kev teeb tsa siv feem ntau ntawm cov yeeb nkab loj hauv (50mm ~ 400mm) sab hauv txoj kab uas hla ntau yam kev saib xyuas transducer tsim sib luag ntawm kab nruab nrab ntawm kev teeb tsa cov yeeb nkab.
Tus nqi sib nrug uas pom ntawm lub qhov rai M25 yog qhov deb ntawm qhov sib nrug sab hauv ntawm ob lub transducers. Qhov sib nrug ntawm cov transducers tiag tiag yuav tsum ze li sai tau rau tus nqi sib nrug. Qhov sib nrug ntawm cov transducer yog los ntawm qhov kawg ntawm ib lub transducer mus rau lwm lub sensor.
Qhov chaw nruab nrab ntawm cov transducer mounting yog qhov tseem ceeb heev rau Transit-time meters, thiab cov neeg siv xav tau mount transducers raws nraim li qhov chaw nruab nrab ntawm tus nqi M25 tom qab cov neeg siv nkag mus rau qhov chaw teeb tsa kom raug. M91 tsuas yog rau kev siv xwb, thiab tsuas yog khaws cia rau hauv 97–103% tus nqi ntau.
Raws li daim duab saum toj no qhia, qhov sib nrug ntawm lub transducer ib txwm yog qhov deb ntawm ob lub transducer kawg (raws li ob kab liab qhia). Thiab qhov sib nrug no yuav tsum yog raws nraim li tus nqi M25 qhia rau koj. Nco ntsoov tias txoj kev no haum rau lub transducer Me, Std. M thiab Loj ib txwm.
Kev Teeb tsa Transducers hauv Z-Mount Configuration Kev teeb tsa rau ntawm cov kav dej loj dua yuav tsum tau ntsuas kom zoo rau qhov chaw linear thiab radial ntawm L1 transducers. Yog tsis teeb tsa thiab tso cov transducers rau ntawm cov kav dej kom raug yuav ua rau lub zog teeb liab tsis muaj zog thiab/lossis nyeem tsis raug. Ntu hauv qab no piav qhia txog txoj hauv kev rau kev nrhiav cov transducers kom raug ntawm cov kav dej loj dua. Txoj kev no yuav tsum tau yob ntawv xws li daim ntawv khov lossis daim ntawv qhwv, daim kab xev thiab lub cuab yeej cim.
1. Qhwv daim ntawv ncig lub yeeb nkab raws li qhia hauv Daim Duab 2.4. Kho cov ntawv kawg kom sib npaug li ntawm 0.25 nti [6 hli].
2. Kos cim qhov kev sib tshuam ntawm ob sab kawg ntawm daim ntawv los qhia qhov ncig.
Tshem daim qauv thiab nthuav nws tawm rau ntawm ib qho chaw tiaj tus. Quav daim qauv ua ib nrab, thiab txiav qhov ncig ntawm daim duab. Saib Daim Duab 2.5.
3. Ua kom daim ntawv nkhaus ntawm kab uas quav. Kos lub cim ntawm qhov nkhaus. Muab ib lub cim rau ntawm lub yeeb nkab uas yuav muaj ib lub transducers nyob. Saib Daim Duab 2.1 rau qhov kev taw qhia radial uas siv tau. Qhwv lub template rov qab ncig lub yeeb nkab, muab qhov pib ntawm daim ntawv thiab ib lub ces kaum tso rau hauv qhov chaw ntawm lub cim. Txav mus rau sab tod ntawm lub yeeb nkab thiab cim lub yeeb nkab ntawm qhov kawg ntawm qhov nkhaus. Ntsuas los ntawm qhov kawg ntawm qhov nkhaus ncaj qha hla lub yeeb nkab los ntawm thawj
qhov chaw ntawm lub transducer) qhov loj me uas tau muab los ntawm Kauj Ruam 2, Qhov Chaw Ntawm Lub Transducer. Kos qhov chaw no rau ntawm lub yeeb nkab.
4. Ob lub cim ntawm cov yeeb nkab tam sim no tau teeb tsa thiab ntsuas kom raug.
Yog tias kev nkag mus rau hauv qab ntawm lub yeeb nkab tsis pub daim ntawv qhwv ncig lub voj voog, txiav ib daim ntawv kom tau raws li cov qhov ntev no thiab muab tso rau saum lub yeeb nkab.
Ntev = Yeeb Nkab OD x 1.57; dav = Qhov nrug tau txiav txim siab ntawm nplooj ntawv 2.6
Kos cov ces kaum ntawm daim ntawv rau ntawm lub yeeb nkab. Siv cov transducers rau ob lub cim no.
5. Muab ib lub hlaws dai ntawm cov couplant, kwv yees li 0.05 nti [1.2 hli] tuab, rau ntawm lub ntsej muag tiaj tus ntawm lub transducer. Saib Daim Duab 2.2. Feem ntau, cov roj silicone-based siv ua acoustic couplant, tab sis txhua yam roj zoo li cov khoom uas tau ntsuas tias tsis "ntws" ntawm qhov kub uas
cov yeeb nkab yuav ua haujlwm ntawm, yuav txais tau.
a) Muab lub transducer upstream tso rau hauv qhov chaw thiab ruaj ntseg nrog txoj hlua khi hlau tsis xeb lossis lwm yam. Cov hlua khi yuav tsum muab tso rau hauv qhov arched groove ntawm qhov kawg ntawm lub transducer. Muaj ib lub ntsia hlau muab.
b) Sim pab tuav lub transducer rau ntawm txoj siv. Xyuas kom tseeb tias lub transducer ncaj nraim rau lub yeeb nkab - kho raws li qhov tsim nyog. Nias txoj siv kom ruaj khov. Cov yeeb nkab loj dua yuav xav tau ntau dua ib txoj siv kom ncav cuag qhov ncig ntawm lub yeeb nkab.
6. Muab lub transducer downstream tso rau ntawm lub yeeb nkab ntawm qhov sib nrug ntawm lub transducer uas tau xam. Saib Daim Duab 2.6. Siv tes nias kom ruaj khov, maj mam txav lub transducer mus rau thiab tawm ntawm lub transducer upstream thaum saib lub zog ntawm lub teeb liab. Tuav lub transducer rau ntawm qhov chaw uas pom lub zog ntawm lub teeb liab siab tshaj plaws. Lub zog ntawm lub teeb liab ntawm 60 thiab 95 feem pua yog qhov siv tau. Ntawm qee lub yeeb nkab, kev tig me ntsis rau lub transducer yuav ua rau
lub zog teeb liab kom nce mus txog qib uas txais tau.
7. Ruaj ntseg lub transducer nrog ib txoj hlua stainless hlau lossis lwm yam.
