Yintoni i-Vortex Flow Meter?
A imitha yokuhamba kwe-vortexsisixhobo esifakwe kwisixokelelwano sokuqukuqela sokukhangela i-vortices eyenziwa njengoko ulwelo ludlula kumzimba we-bluff. Isetyenziswa kakhulu kwigesi, ulwelo kunye nokusetyenzwa komphunga kumlinganiselo wokuqukuqela ukuphucula imveliso esebenzayo kunye nokwabiwa.
Umgaqo wokuSebenza weVortex Flow Meter
I-Vortices ichithwa ngokutshintshanayo ukusuka kwicala ngalinye lomzimba we-bluff xa ulwelo ludlula kwinto engalungelelaniswanga. Iiyantlukwano zoxinzelelo ezenziwa kwinkqubo zihambelana ngokuthe ngqo nesantya sokuhamba. Ukuphindaphinda kokuchithwa kwe-vortex kuchongiwe ukubala izinga lokuhamba. Emva koko i-frequency iya kuguqulelwa kumqondiso onika umlinganiselo ochanekileyo wevolumu okanye ukuhamba kobunzima bolwelo, iigesi kunye nomphunga.
Uyilo loLwakhiwo lweemitha zokuHamba zeVortex
I-316 insimbi engenasici okanye i-Hastelloy yinto ephambili eyenziwe ngemitha yokuhamba ngokuqhelekileyo, kuquka umzimba we-bluff, i-vortex sensor edibeneyo kunye ne-transmitter electronics. Aimitha yokuphalaza i-vortexifumaneka ngobukhulu flange ukusuka ½ in. ukuya 12 in. Ngaphezu koko, ixabiso ufakelo aimitha yokulahla i-vortexiyakhuphisana kunaleyo yeemitha ze-orifice ngobukhulu ngaphantsi kwee-intshi ezintandathu.
Imilinganiselo kunye neemilo zomzimba bluff ezifana nesikwere kunye noxande baye badlula kwiimvavanyo ukufikelela kwiziphumo ezinqwenelekayo. Iziphumo zovavanyo zibonisa ukuba umgca kunye novakalelo kwiprofayile yesantya zahluke kancinane ngobume bomzimba obubluff. Umzimba we-bluff kufuneka ube neqhekeza elikhulu elaneleyo lobubanzi bombhobho. Emva koko lonke uhambo luthatha inxaxheba ekuchitheni. Ngaphandle komyinge wokuhamba, imiphetho egqamileyo kumsinga ongasentla luyilo oluyimfuneko olukhethekileyo lokwaba imigca yokuqukuqela yokwahlula.
Okwangoku, uninzi lweemitha ze-vortex zidibanisa i-piezoelectric okanye i-capacitance-type sensors ukulinganisa i-oscillation yoxinzelelo kufuphi nomzimba we-bluff. Ezi zinzwa zikhupha umqondiso we-voltage ephantsi njengempendulo kwi-oscillation yoxinzelelo. Imiqondiso enjalo ine-frequency efanayo njenge-oscillation. Ezo zinzwa zemodyuli nezingabizi kakhulu zinokutshintshwa ngokulula kwaye zilungelelaniswe kuluhlu olubanzi lobushushu ukusuka kulwelo lwe-cryogenic ukuya kumphunga oshushu kakhulu.
Kutheni ukhetha iVortex Flow Meters?
Akukho zixhobo ezihambayo ziqinisekisa ukuqina, ukugcinwa okuphantsi kunye nokuthembeka kwexesha elide kwinkqubo yokucubungula. Ezo mitha zokuqukuqela zikwagqama ekulinganiseni uluhlu olwahlukeneyo lolwelo ngokuchanekileyo, nakumazinga obushushu ahlukeneyo kunye noxinzelelo. Ngokuchanekileyo ngenxa yobuninzi bemisebenzi kunye nokusebenza okubalaseleyo kwimilinganiselo echanekileyo kunye nokuphindaphindwayo, zizisombululo kumashishini axabisa ukuchaneka. Iindleko zokusebenza ezicuthiweyo kunye nofakelo olulula zizizathu ezibini ngakumbi njengesisombululo sokuya.
Ukuchaneka kunye nokuHlangana
Uluhlu lwee-vortex flowmeters luyehla njengoko i-viscosity inyuka ngenxa yokuwa kwenani le-Reynolds kunye ne-viscosity enyukayo. Ubuninzi be-viscosity ceilling bulele ngaphakathi kwe-8 ~ 30 centipoises. Kwimeko apho imitha ye-vortex ilinganiswe ngokufanelekileyo kwisicelo, umntu unokulindela ukulungelelaniswa okungcono kune-20: 1 yegesi kunye ne-steam, kunye ne-10: 1 ye-low-viscosity fluids.
Ukungachaneki kweemitha zokuhamba kwe-vortex kuyahluka ngeenombolo zeReynolds. Ukungachaneki okunjalo kwe-vortex flowmeters kuphumle phakathi kwe-0.5% kunye ne-1% ngelixa inyuka ukuya kuthi ga kwi-10% xa inani le-Reynolds lingaphantsi kwe-10,000. Imitha ye-vortex ibonakalisa indawo esikiweyo yezalathisi kufutshane nokuhamba kweqanda. Iziphumo zemitha zibanjelwe ku-zero xa ii-Reynolds iinombolo okanye ngaphantsi kwe-10,000. Akukho ngxaki kwimeko apho ubuncinci bomqukuqelo obulindele umlinganiselo ngamaxesha amabini kwindawo yokunqunyulwa. Amazinga okuhamba okuphantsi awakwazanga ukulinganiswa ngokuchanekileyo kwinkqubo yokuqalisa, ukuvala kunye nezinye iimeko eziphazamisayo zoluhlu lwazo.
Yandisa ukusebenza ngokukuko kwaye unciphise iindleko
Abaqhubi bayakwazi ukulungelelanisa kunye nokwandisa ukuhamba kolwelo, iigesi okanye umphunga othumela ngenkqubo yokucubungula ngokuxhomekeke kumlinganiselo ochanekileyo wokuhamba. Ukuze unikezelo olusebenzayo luphuculwe ngelixa ukusetyenziswa kwamandla kuthotywa. Kukho konke, ukudibanisa ezi mitha zokuhamba kwiinkqubo zokuzenzekelayo ziluncedo ekuphuculeni okuqhubekayo ekusebenzeni kokusebenza, ukunciphisa ixesha lokunciphisa kunye nokuphucula imveliso jikelele.
Unyino lweVortex Flowmeter
Iimitha zeVortex ngokuqhelekileyo azifanelekanga kwi-batching okanye iinkqubo zokuhamba ngokukhawuleza ngenxa yokunciphisa ukusebenza kwazo kumazinga aphantsi okuhamba. Ngokukodwa, isantya sokuhamba kwedribble yezikhululo zokubethelwa singawela ngaphantsi kwe-vortex yemitha ye-vortex yenani elisezantsi lomqobo wenombolo yeReynolds, ekhokelela kukungachaneki. Njengoko ubungakanani bebhetshi bubonke buncipha, amathuba okuba neempazamo zomlinganiselo ayanda, nto leyo eyenza ukuba imitha ithembeke kangako kwezi zicelo. Kubalulekile ukukhetha isilinganisi-manzi esinokusingatha iprofayili ethile yokuqukuqela efunekayo kwimisebenzi enjalo ukunqanda iimpazamo ezibalulekileyo.
