Thaum siv lub precessing vortex flow meter los ntsuas qhov ntsuas tag nrho, cov teeb meem hauv qab no yuav tsum xav txog:
1. Cov kav dej ntws tawm yuav tsum yog 2 × 104 ~ 7 × 106. Yog tias nws dhau qhov ntau, qhov ntsuas ntawm qhov ntsuas ntsuas, uas yog, tus lej Stroha tsis yog qhov ntsuas, thiab qhov tseeb yuav txo qis.
2. Tus nqi ntws ntawm nruab nrab yuav tsum nyob rau hauv qhov yuav tsum tau muaj, vim hais tias lub precession vortex flow meter ntsuas tag nrho cov ntws raws li qhov zaus. Yog li ntawd, qhov ntws ntawm qhov nruab nrab yuav tsum raug txwv, thiab cov nruab nrab sib txawv muaj qhov sib txawv.
(1) Thaum nruab nrab yog vapor, max tshaj tawm yuav tsum qis dua 60 m / s
(2) Thaum nruab nrab yog chav, nws yuav tsum qis dua 70 m / s
(3) Tus nqi qis qis qis yog xam los ntawm tus txheeb ze nkhaus daim duab lossis cov qauv kev suav ntawm cov ntsuas vaj huam sib luag raws li qhov viscosity thiab txheeb ze ntom ntom
(4) Tsis tas li ntawd, kev ua haujlwm siab thiab qhov kub ntawm qhov nruab nrab yuav tsum nyob hauv qhov xav tau.
Cov yam ntxwv ntawm precession vortex flow meter.
1. Cov txiaj ntsig tseem ceeb
(1) Qhov ntsuas ntsuas ntsuas ntawm lub ntsuas yuav tsis raug mob los ntawm cov kua dej ua haujlwm siab, qhov kub thiab txias, txheeb ze ntom ntom, viscosity thiab muaj pes tsawg leeg hloov pauv, thiab tsis tas yuav rov ntsuas dua thaum disassembling thiab hloov cov khoom kuaj xyuas;
(2) Qhov ntsuas qhov sib piv yog qhov loj, cov kua nce mus txog 1:15, thiab vapor mus txog 1:30;
(3) Cov kav dej tshwj xeeb yuav luag tsis txwv, 25-2700 Mm;
(4) Kev puas tsuaj rau kev ua haujlwm yog me me;
(5) Tam sim ntawd tso tawm cov teeb liab hluav taws xob linearly ntsig txog tag nrho cov ntws, nrog siab precision, ncav cuag ± 1%;
(6) Kev teeb tsa yooj yim, kev saib xyuas tus nqi me me, thiab cov kev ua txhaum feem ntau tsawg heev.
2. Qhov tseem ceeb tsis xws luag
(1) Qhov sib txawv ntawm qhov ntws thiab cov dej haus pulsating yuav ua rau muaj kev phom sij rau qhov ntsuas qhov tseeb. Muaj cov kev cai rau kev sib txuas ntawm sab sauv, nruab nrab thiab qis qis ntawm lub ntsuas vaj huam sib luag (peb d dej ntws thiab qis qis, 1D hauv nruab nrab thiab qis). Yog tias tsim nyog, lub rectifier yuav tsum tau hloov kho nyob rau sab saud thiab hauv qab;
(2) Thaum cov tshuaj ntsuam xyuas cov khoom qias neeg, qhov ntsuas qhov tseeb yuav raug cuam tshuam. Tag nrho cov khoom ntws thiab cov qhov tshuaj ntsuam xyuas yuav tsum tau ntxuav nrog lub tsheb roj av, roj av, ethanol, thiab lwm yam raws sijhawm.
3. Kev teeb tsa ntawm precession vortex flowmeter
1. Thaum lub flowmeter yog ntsia, nws yog txwv tsis pub nqa tawm arc vuam tam sim ntawd ntawm lub flange ntawm nws ntshuam thiab export kev lag luam los mus tiv thaiv burning qhov chaw ntawm lub flowmeter.
2. Sim ntxuav cov raj xa dej tshiab los yog kho dua tshiab, thiab txhim kho lub flowmeter tom qab tshem cov av hauv cov kav dej.
3. Lub flowmeter yuav tsum tau muab tso rau hauv ib qho chaw uas tsim nyog rau kev saib xyuas, tsis muaj kev cuam tshuam ntawm cov hlau nplaum muaj zog, thiab tsis muaj qhov pom tseeb damping vibration thiab radiant tshav kub txaus ntshai;
4. Lub flowmeter tsis haum rau qhov chaw uas tag nrho cov dej ntws feem ntau cuam tshuam thiab muaj qhov pom tseeb pulsating dej ntws los yog ua haujlwm siab pulsating dej haus;
5. Thaum lub flowmeter raug ntsia sab nraum zoov, yuav tsum muaj lub hau npog ntawm qhov kawg kom tiv thaiv kev nkag mus ntawm nag lossis daus los ntawm kev ua phem rau lub neej ntawm flowmeter;
6. Lub flowmeter tuaj yeem ntsia tau ntawm txhua lub kaum sab xis ntawm qhov pom, thiab cov dej ntws ntawm cov kua dej yuav tsum ua raws li cov dej ntws tau cim rau ntawm lub ntsuas ntsuas;
7. Nyob rau ntawm qhov chaw tsim kho cov kav dej, kev txiav txim siab yuav tsum tau muab rau kev txhim kho cov khoom lossis cov tshuab hlau txhawm rau tiv thaiv kev rub los yog tawg ntawm lub flowmeter;
8. Lub flowmeter yuav tsum tau nruab coaxially nrog cov yeeb nkab tso zis, thiab tiv thaiv lub sealing piece thiab unsalted butter kom nkag mus rau sab hauv phab ntsa ntawm cov kav dej;
9. Thaum siv lub zog hloov hluav taws xob sab nraud, lub flowmeter yuav tsum muaj cov khoom siv hauv av txhim khu kev qha. Cov xaim hauv av tsis tuaj yeem siv nrog cov software tsis muaj zog tam sim no. Thaum lub sij hawm installation los yog txij nkawm, lub grounding hlau ntawm lub arc vuam system software yuav tsis tau overlapped nrog lub flowmeter steel bar. .
