Yim Pitfalls hauv Xaiv Vortex Flow Meter
Vortex flow meter tau dav siv rau chav dej, roj thiab ntsuas dej, tab sis kev xaiv tsis raug tuaj yeem ua rau koj cov peev txheej tsis muaj nqis. Nov yog yim pitfalls tseem ceeb kom tsis txhob:
- Tsis quav ntsej cov kev txwv qisVortex meters yuav tsum muaj qhov tsawg kawg nkaus tshaj tawm (steam ≥8 m/s, gas ≥5 m/s). Hauv qab no, tsis muaj teeb liab tawm.
- Tsis txaus ncaj yeeb nkab ntevLawv feem ntau xav tau 10D sab sauv thiab 5D cov kav dej ncaj nraim. Yog tsis muaj lub rectifier nyob rau hauv qhov chaw nruj, ntsuas qhov yuam kev surge.
- Qhov muag tsis pom kev xaiv cov hlaws loj lojIb lub 'meter' loj dhau ntawm qhov qis qis thiab ntau dhau ntawm cov dej ntws siab, ua rau nws siv tsis tau.
- Kev ntsuas kub tsis sib haum thiab kev ntsuas siabSiv cov ntsuas ntsuas rau qhov kub thiab txias ua rau muaj kev puas tsuaj, tawg thiab tsis ua haujlwm.
- Tsis muaj pov thawj tawg nyob rau hauv qhov chaw muaj kev phom sijCov ntsuas tsis yog tawg-pov thawj nyob rau hauv ib puag ncig flammable tsim muaj kev nyab xeeb loj heev.
- Cov khoom tsis raug rau corrosive mediaOrdinary stainless hlau corrodes sai, shortening kev pab cuam lub neej drastically.
- Tsis quav ntsej cov yeeb nkab kev coKev vibration cuam tshuam nrog Karman vortex txoj cai, ua rau kev ntsuas loj cuam tshuam.
- Cov kab hluav taws xob tsis zoo rau kev sib cais hom ntsuasKev siv cable txuas ntxiv lossis siv cov kab hluav taws xob zoo tib yam ua rau lub teeb liab attenuation thiab kis tsis tau.
Txhawm rau kom ntseeg tau tias kev ntsuas txhim khu kev qha thiab zam cov nqi khib nyiab, lees paub cov txheej txheem tag nrho ua ntej lossis sab laj cov kws tshaj lij rau kev xaiv kom raug.
