Tus neeg sawv cev txuas ua rau muaj kev sib kis tau zoo ntawm cov nthwv dej ultrasonic ntawm lub transducer thiab lub raj phab ntsa sib cuag nto. Kev teeb tsa ntev (ruaj khov) thiab kev teeb tsa luv luv (mobile) yuav tsum siv ntau hom kev sib txuas. Kev siv ntev ntawm kev sib txuas yog Araldites thiab cov resins epoxy tsis tiav (cov khoom sau yuav tawg cov nthwv dej ultrasonic). Cov kev sib txuas ruaj khov tas mus li yuav tsum tau kuaj xyuas tsis tu ncua, lub voj voog tshuaj xyuas tau teev los ntawm cov chaw tsim khoom raws li nws hom, thiab kev ua haujlwm kuaj mob ntawm lub ultrasonic flowmeter nws tus kheej tuaj yeem siv los xyuas thaum twg nws yuav tsum tau hloov. Tus neeg sawv cev txuas luv luv daim ntawv thov suav nrog: roj silicone, roj qag thiab lwm yam. Yuav kom ntseeg tau tias lawv tsis qhuav, nws raug pom zoo kom extrude lub coupling ntawm 3 txog 4 hli tuab thiab txog 5 hli hauv txoj kab uas hla txhua lub sijhawm, thiab siv nws raws txoj kab ntawm lub transducer, thiab tom qab ntawd nias nws rau lub raj phab ntsa. Cov kev ntsuas ua ntej thiab kev ceev faj hauv qab no yuav tsum tau ua ua ntej pov tseg lub coupler:
1. Phab ntsa sab nraud ntawm lub raj uas lub transducer tau teeb tsa yuav tsum huv si thiab tsis muaj roj. Yog tias muaj ib txheej txheej lossis lwm txheej npog, nws yuav tsum tau tshem tawm, tshwj xeeb tshaj yog rau cov txheej npog uas muaj fiber thiab hlau mesh.
2. Thaum cuam tshuam nrog phab ntsa yeeb nkab, nws yog qhov tsim nyog los tswj cov kab puag ncig qub ntawm cov yeeb nkab, thiab khaws qhov chaw ntawm lub transducer sib luag rau qhov kev taw qhia axial ntawm cov yeeb nkab, vim tias qhov yuam kev ntawm 1 degree yuav hloov qhov ntev ntawm txoj kev acoustic ntawm 1% txog 2%.
3. Tsis txhob siv lub coupler ntau dhau, yuav tsum ua haujlwm ceev faj heev kom tiv thaiv kev sib kis ntau dhau, kom tsis txhob sib xyaw coupler rau hauv huab cua.
4. Nyob rau hauv ib puag ncig ntawm hmoov av thiab flocculent, peb yuav tsum tau them sai sai kom tiv thaiv kev sib tov ntawm lwm yam impurities, vim tias hmoov av thiab flocculent yuav txo qhov coupling effect, thiab nws yog ib qho yooj yim kom qhuav tus neeg sawv cev coupling.
5. Yog tias muaj qhov hauv phab ntsa ntawm lub raj, siv cov tshuaj sib txuas kom txaus los sau lawv thiab tsim kom muaj txoj kev suab tag nrho. Yog tias lub raj yog yas, qhov saum npoo ntawm lub raj yuav tsum tau txhuam me ntsis kom ntseeg tau tias cov tshuaj sib txuas xws li epoxy resin lo rau kom txaus.
6. Ua tib zoo xaiv thiab siv cov coupler hauv qab qhov kub sib txawv, thiab sab laj nrog tus neeg muag khoom ntawm coupler hauv qab qhov xwm txheej ua haujlwm tsis zoo.
7. Cov coupler uas ua los ntawm dej yuav raug evaporated ntawm qhov kub siab, khov ntawm qhov kub qis thiab hloov cov yam ntxwv; Cov couplings uas ua los ntawm roj yuav ntws ntawm qhov kub siab, thiab qee cov couplings yuav hloov kev ua tau zoo ntawm qhov kub qis.
8. Thaum qhov kub qis (xws li cov pa oxygen, cov nitrogen kua, thiab lwm yam), cov hlau indium series coupling pieces tuaj yeem xaiv tau.
9. Thaum kub dua (130C ~ 200C), cov ntawv txuas hlau ua ke tuaj yeem xaiv tau.
10. Thaum kub siab (200C ~ 400C), koj tuaj yeem xaiv cov hlau nyiaj series coupling piece.
11. Hauv qhov chaw ntub dej lossis hauv qab dej, cov khoom siv roj hmab tshwj xeeb tuaj yeem siv tau.
