Iyini i-Vortex Flow Meter?
A i-vortex flow meteriyidivayisi efakwe kusistimu yokucubungula ukugeleza ukuze kutholwe ama-vortices akhiqizwa njengoba uketshezi ludlula umzimba we-bluff. Isetshenziswa kakhulu ekucubunguleni igesi, uketshezi kanye nesitimu ukuze kulinganiswe ukugeleza ukuze kuthuthukiswe ukusebenza kahle kokukhiqiza kanye nokwabiwa.
I-Vortex Flow Meter Working Principle
Ama-vortice athululwa ngokushintshana ohlangothini ngalunye lomzimba we-bluff lapho uketshezi ludlula entweni engahlelekile. Izinguquko zengcindezi ezikhiqizwa ohlelweni zilingana ngokuqondile nesivinini sokugeleza. Imvamisa yokuchitheka kwe-vortex itholwa ukuze kubalwe izinga lokugeleza. Khona-ke i-frequency izohumushwa ibe isignali ehlinzeka ngesilinganiso esinembile sevolumu noma ukugeleza kwesisindo soketshezi, amagesi, nesitimu.
Idizayini yesakhiwo ye-Vortex Flow Meters
I-316 Stainless steel noma i-Hastelloy iyinto eyinhloko eyenziwe ngemitha yokugeleza ejwayelekile, okuhlanganisa nomzimba ongenalutho, inzwa ye-vortex ehlanganisiwe kanye nogesi wokudlulisa. Ai-vortex shedding flow meteritholakala ngosayizi be-flange ukusuka ku-½ in. ukuya ku-12 in. Ngaphezu kwalokho, izindleko zokufakwa kwe-imitha yokulahla i-vortexiyaqhudelana kunaleyo yamamitha e-orifice ngosayizi ngaphansi kwamayintshi ayisithupha.
Ubukhulu kanye nokwakheka komzimba okufiphele njengesikwele nonxande kudlule ekuhlolweni ukuze kufinyelelwe emiphumeleni oyifunayo. Imiphumela yokuhlola ibonisa ukuthi umugqa kanye nokuzwela kuphrofayela yesivinini kuhluke kancane ngokuma komzimba okufiphele. Umzimba we-bluff kufanele uqukathe ingxenye enkulu eyanele yobubanzi bepayipi. Khona-ke wonke ukugeleza iqhaza ekuchithekeni. Naphezu kwezinga lokugeleza, imiphetho evulekile ebusweni obuphezulu bomfula iyimiklamo ekhethekile edingekayo ukuze kwabiwe imigqa yokuhlukana kokugeleza.
Njengamanje, iningi lamamitha we-vortex lihlanganisa izinzwa zohlobo lwe-piezoelectric noma i-capacitance ukuze kulinganiswe i-oscillation yokucindezela eduze komzimba we-bluff. Lezi zinzwa zikhipha isignali ye-voltage ephansi njengokuphendula i-oscillation yokucindezela. Izimpawu ezinjalo zinemvamisa efanayo ne-oscillation. Lezo zinzwa ze-modular nezingabizi zingashintshwa kalula futhi zivumelane nezimo ebangeni elibanzi lokushisa ukusuka oketshezini lwe-cryogenic ukuya kusitimu esishisa kakhulu.
Kungani Khetha I-Vortex Flow Meters?
Azikho izingxenye ezihambayo eziqinisekisa ukuqina, ukugcinwa okuphansi nokuthembeka kwesikhathi eside ohlelweni lokucubungula. Ama-flow metre anjalo nawo agqama ekukaleni uketshezi oluhlukahlukene ngokunembile, ngisho nakumazinga okushisa ahlukahlukene nezingcindezi. Impela ngenxa yobuningi bemisebenzi kanye nokusebenza okuvelele ekulinganiseni okunembayo nokuphindaphindwayo, kuyizixazululo zokuya ezimbonini ezilinganisa ukunemba. Ukwehliswa kwezindleko zokusebenza nokufaka kalula yizizathu ezimbili ezengeziwe njengesixazululo sokuya kuso.
Ukunemba kanye Rangeability
Ukuhlukahluka kwama-flowmeters e-vortex kuncipha njengoba i-viscosity ikhula ngokuwa kwenombolo ye-Reynolds ngokukhuphuka kwe-viscosity. Isilingi se-viscosity esiphezulu singaphakathi kwama-centipoise angu-8 ~ 30. Esimeni lapho imitha ye-vortex ilinganiswe ngokufanelekile ngohlelo lokusebenza, umuntu angalindela ububanzi obungcono kuno-20:1 kugesi nesitimu, nangaphezulu kuka-10:1 kuketshezi olune-viscosity ephansi.
Ukunemba kwamamitha okugeleza kwe-vortex kuyahluka ngezinombolo ze-Reynolds. Ukunemba okunjalo kwama-flowmeters amaningi e-vortex kuphakathi kuka-0.5% no-1% kuyilapho kukhuphukela ku-10% lapho i-Reynolds isibalo esincane kuno-10,000. Imitha ye-vortex inendawo enqamukile yezinkomba eziseduze nokugeleza kukaziro. Okuphumayo kwamamitha kucindezelwa kokuthi ziro lapho u-Reynolds enezinombolo eziku-10,000 noma ngaphansi. Azikho izinkinga uma kwenzeka ukuthi ukugeleza okuncane okulinde ukulinganiswa kuyizikhathi ezimbili zephoyinti lokunqamula. Amazinga okugeleza aphansi awakwazanga ukukalwa ngokunembile enqubweni yokuqala, ukuvala shaqa nezinye izimo eziphazamisekile ngenxa yobubanzi bazo.
Khulisa Ukusebenza Kahle futhi Unciphise Izindleko
Ama-opharetha ayakwazi ukulungisa nokwandisa ukugeleza koketshezi, amagesi noma isitimu esithumela ngesistimu yokucubungula kuncike esilinganisweni sokugeleza esinembile. Ukuze ukwaba ukusebenza kahle kuthuthukiswe ngenkathi ukusetshenziswa kwamandla kwehliswa. Sekukonke, ukuhlanganisa lawa mamitha wokugeleza ezinhlelweni ezizenzakalelayo kuyasiza ekuthuthukisweni okuqhubekayo ekusebenzeni kokusebenza, ukunciphisa isikhathi sokuphumula kanye nokuthuthukisa ukukhiqiza okuphelele.
Imikhawulo ye-Vortex Flowmeter
Amamitha e-Vortex ngokuvamile awafaneleki ukuhlanganiswa noma izinqubo zokugeleza kwezikhawu ngenxa yemikhawulo yawo yokusebenza ngamanani okugeleza aphansi. Ngokukhethekile, izinga lokugeleza kwe-dribble leziteshi zokunqwabelana lingase liwele ngaphansi komkhawulo wenombolo ye-vortex meter encane ye-Reynolds, okuholela ekungalungeni kahle. Njengoba usayizi weqoqo usuwonke uncipha, amathuba okuba namaphutha okulinganisa ayanda, okwenza imitha ithembeke kancane kulezi zinhlelo zokusebenza. Kubalulekile ukukhetha imitha yokugeleza engakwazi ukuphatha iphrofayela ethile yokugeleza edingekayo emisebenzini enjalo ukuze kugwenywe amaphutha abalulekile.
Ithimba lethu lochwepheshe selilungele ukunikeza izixazululo ezihambisanayo ezihlangabezana nezidingo ezithile zomkhakha wakho, kungakhathaliseki ukuthi uwoyela negesi, ukucubungula amakhemikhali, noma amasistimu e-HVAC. Ngokuzibophezela kwikhwalithi nokusebenza, sinikeza ukwesekwa okuphelele ukuze siqinisekise ukuthi ukhetha imitha yokugeleza ye-vortex efanele yohlelo lwakho lokusebenza. Xhumana nathi namuhla ukuze uthole ukubonisana komuntu siqu futhi ubone ukuthi ama-flow metres ethu angakushintsha kanjani ukulawula kwakho kwenqubo nokusebenza kahle.
