Iyini iVortex Flow Meter?
A imitha yokugeleza kwe-vortexiyithuluzi elifakwe ohlelweni lokucubungula ukugeleza ukuze kutholakale ama-vortices akhiqizwa njengoba uketshezi ludlula emzimbeni we-bluff. Lisetshenziswa kabanzi ekucubungulweni kwegesi, uketshezi kanye nomusi ukuze kulinganiswe ukugeleza ukuze kuthuthukiswe ukusebenza kahle kokukhiqiza kanye nokwabiwa.
Isimiso Sokusebenza Semitha Yokugeleza Kwe-Vortex
Ama-vortice akhishwa ngokushintshana kusukela ohlangothini ngalunye lomzimba oluhlaza lapho uketshezi ludlula entweni engahambisani. Ukushintshashintsha kwengcindezi okukhiqizwa enkambisweni kuhambisana ngqo nesivinini sokugeleza. Imvamisa yokuchitheka kwe-vortex iyatholwa ukuze kubalwe izinga lokugeleza. Ngemuva kwalokho imvamisa izohunyushwa ibe isignali enikeza isilinganiso esinembile sokugeleza kwe-volumetric noma kwesisindo koketshezi, amagesi, kanye nomusi.
Umklamo Wesakhiwo Samamitha Okugeleza Kwe-Vortex
316 Insimbi engagqwali noma i-Hastelloy yinto eyinhloko eyenziwe ngemitha yokugeleza evamile, okuhlanganisa umzimba oluhlaza okwesibhakabhaka, inzwa ye-vortex ehlanganisiwe kanye ne-transmitter electronics.imitha yokugeleza kokuphuma kwe-vortexitholakala ngobukhulu be-flange kusukela ku-½ in. kuya ku-12 in. Ngaphezu kwalokho, izindleko zokufaka ze-aimitha yokuchitha i-vortexiyancintisana kunaleyo yamamitha e-orifice ngobukhulu obungaphansi kwamasentimitha ayisithupha.
Ubukhulu kanye nokwakheka komzimba okuluhlaza okwesibhakabhaka njengesikwele nesikwele kudlule ekuhlolweni ukuze kufinyelelwe imiphumela efiselekayo. Imiphumela yokuhlola ikhombisa ukuthi ukulingana kanye nokuzwela kuphrofayili yejubane kuhlukile kancane ngesimo somzimba okuluhlaza okwesibhakabhaka. Umzimba okuluhlaza okwesibhakabhaka kufanele ube nengxenye enkulu ngokwanele yobubanzi bepayipi. Bese ukugeleza konke kuhlanganyela ekuchitheni. Naphezu kwesilinganiso sokugeleza, imiphetho evelele ebusweni obuphezulu iyimiklamo ekhethekile ebaluleke kakhulu yokwaba imigqa yokuhlukaniswa kokugeleza.
Njengamanje, iningi lamamitha e-vortex lihlanganisa izinzwa zohlobo lwe-piezoelectric noma lwe-capacitance ukuze kulinganiswe ukunyakaza kokucindezela eduze komzimba we-bluff. Lezi zinzwa zikhipha isignali ye-voltage ephansi njengempendulo ku-oscillation yokucindezela. Izimpawu ezinjalo zinemvamisa efanayo ne-oscillation. Lezo zinzwa eziguquguqukayo nezingabizi zingashintshwa kalula futhi zivumelane nezimo ebangeni elikhulu lokushisa kusukela koketshezi oluyi-cryogenic kuya kumusi oshisayo kakhulu.
Kungani Kufanele Ukhethe Amamitha Okugeleza Kwe-Vortex?
Azikho izingxenye ezihambayo eziqinisekisa ukuqina, ukunakekelwa okuphansi kanye nokuthembeka kwesikhathi eside ohlelweni lokucubungula. Lawo mamitha okugeleza avelele futhi ekulinganiseni uhlu oluhlukahlukene loketshezi ngokunembile, ngisho nasezingeni lokushisa elibanzi kanye nokucindezela. Ngenxa yokusebenza okuningi kanye nokusebenza okuhle kakhulu ekulinganiseni ngokunemba nangokuphindaphindeka, ayizixazululo ezisetshenziswa kakhulu ezimbonini ezibheka ukunemba njengokufanele. Izindleko zokusebenza ezincishisiwe kanye nokufakwa okulula yizizathu ezimbili ezengeziwe njengesixazululo esisetshenziswa kakhulu.
Ukunemba Nokuguquguquka
Ukusabalala kwama-vortex flowmeters kwehla njengoba i-viscosity ikhuphuka yokuwa kwenombolo kaReynolds lapho i-viscosity ikhuphuka. Ukuphakama okuphezulu kwe-viscosity ceiling kungaphakathi kwama-centipoise angu-8 ~ 30. Uma kwenzeka ukuthi i-vortex meter ilinganiswe kahle ukuze isetshenziswe, umuntu angalindela ukusabalala okungcono kune-20:1 yegesi kanye ne-steam, kanye ne-10:1 yoketshezi olune-viscosity ephansi.
Ukungalungi kwamamitha okugeleza kwe-vortex kuyahlukahluka ngezinombolo zikaReynolds. Ukungalungi okunjalo kwamamitha okugeleza kwe-vortex amaningi kuphakathi kuka-0.5% no-1% kuyilapho kukhuphuka kufike ku-10% lapho uReynolds engaphansi kuka-10,000. Imitha ye-vortex inephuzu lokuvala izinkomba lapho ukugeleza okuseduze kuka-zero kufinyelelwa khona. Imiphumela yamamitha ivalwa ku-zero lapho uReynolds ebalelwa ku-10,000 noma ngaphansi. Azikho izinkinga uma ukugeleza okuncane okulindele ukukalwa kuphindwe kabili kwephuzu lokuvala. Amazinga okugeleza aphansi awakwazanga ukulinganiswa ngokunembile enkambisweni yokuqalisa, ukuvala kanye nezinye izimo zokuphazanyiswa ngenxa yokukwazi kwawo ukuhamba.
Khulisa Ukusebenza Kahle Futhi Unciphise Izindleko
Abasebenzi bayakwazi ukulungisa nokwenza ngcono ukugeleza koketshezi, amagesi noma umusi othumela ohlelweni lokucubungula ngokuthembela ekulinganisweni okunembile kokugeleza. Ukuze ukusebenza kahle kokwabiwa kuthuthukiswe ngenkathi ukusetshenziswa kwamandla kwehla. Sekukonke, ukuhlanganisa lawa mamitha okugeleza ezinhlelweni ezizenzakalelayo kuyasiza ekuthuthukiseni okuqhubekayo ekusebenzeni kokusebenza, ukunciphisa isikhathi sokungasebenzi kanye nokuthuthukisa umkhiqizo jikelele.
Imikhawulo ye-Vortex Flowmeter
Amamitha e-Vortex ngokuvamile awafaneleki ekuhlanganiseni noma ekuqhubekeni kokugeleza ngenxa yemikhawulo yokusebenza kwawo emazingeni okugeleza aphansi. Ngokukhethekile, izinga lokugeleza lokugeleza kweziteshi zokuhlanganisa lingase liwe ngaphansi komkhawulo omncane wenombolo ye-vortex meter kaReynolds, okuholela ekungalungini. Njengoba usayizi weqoqo lonke wehla, amathuba amaphutha okulinganisa ayanda, okwenza imitha ingathembeki kangako kulezi zinhlelo zokusebenza. Kubalulekile ukukhetha imitha yokugeleza engaphatha iphrofayili ethile yokugeleza edingekayo emisebenzini enjalo ukuze kugwenywe amaphutha amakhulu.
Ithimba lethu lochwepheshe likulungele ukunikeza izixazululo ezenzelwe wena ezihlangabezana nezidingo ezithile zomkhakha wakho, kungaba uwoyela negesi, ukucubungula amakhemikhali, noma izinhlelo ze-HVAC. Ngokuzibophezela kwikhwalithi nokusebenza kahle, sinikeza ukwesekwa okuphelele ukuqinisekisa ukuthi ukhetha imitha yokugeleza ye-vortex efanele yesicelo sakho. Xhumana nathi namuhla ukuze uthole ukubonisana komuntu siqu futhi ubone ukuthi amamitha ethu okugeleza angaguqula kanjani ukulawula kwakho inqubo kanye nokusebenza kahle.
