Ama-Vortex flowmeterszisebenza ngokusekelwe kumgomo we-Kármán vortex street. Ngenxa yezici zazo ezifana nokunemba okuphezulu, isilinganiso sokujika okubanzi, kanye nokungabi nezingxenye ezihambayo, ama-vortex flowmeter asetshenziswa kabanzi ekulinganisweni kokugeleza komusi, igesi, kanye noketshezi. Kodwa-ke, lawa mathuluzi azwela kakhulu ezimweni zokugeleza koketshezi, futhi ukusebenza kwawo okuphezulu kungase kungenzeki ngokugcwele ngaphansi kwazo zonke izimo zokusebenza. Uma kukhona ukuntuleka kokuqonda okujulile kwezimo zenqubo noma ukunaka okwanele imininingwane yendawo yokufaka, leli thuluzi lokunemba lingabhekana kalula nezinkinga ezifana nokufundwa okungavamile, amaphutha akhuphukile, kanye nama-alamu avamile. Ngakho-ke, kusukela ekukhetheni imodeli kuya ekufakweni, ukulinganisa kokusebenza kuzo zonke izigaba kubalulekile ukuqinisekisa ukusebenza kokugcina kwe-vortex flowmeter.
Ukukhetha imodeli
Ukuvumelanisa ukukhetha kuhambisane nohlelo lokusebenza oluthile kuyimfuneko yokulinganisa okunembile. Inqubo yokukhetha kumele igxile ekufanisweni okunembile kwezinto ezintathu eziyinhloko: ububanzi bokugeleza, ububanzi bepayipi kanye nezici eziphakathi nendawo, ukuze kugwenywe izinkinga ezibangelwa ukukhetha okungafanele okungadinga ukuguqulwa okulandelayo.
Ukuqhathaniswa Kwebanga:Izinga langempela lokugeleza kwenqubo kufanele liwele ngaphakathi kuka-20% kuya ku-80% webanga lethuluzi. Uma izinga lokugeleza liwela ngaphansi kuka-20%, isignali ye-vortex ibuthakathaka futhi isengozini yokunganakwa ngenxa yomsebenzi ophansi wokunqamula ukugeleza (okuholela ekufundweni kokugeleza okungu-0). Uma idlula u-80%, ingase idlule umkhawulo wokubekezelela okuphezulu kwenzwa (isb., umonakalo ongaphezu kwamandla ezinzwa ze-piezoelectric).
Ukufaniswa kwe-DN:Ububanzi obujwayelekile (i-DN) be-ortex flowmeter kufanele bufane nosayizi wepayipi lenqubo ukuze kugwenywe ngempumelelo ukuphazamiseka kokugeleza okubangelwa umehluko wosayizi we-DN. Kodwa-ke, ezimweni lapho ipayipi lenqubo likhulu kodwa izinga lokugeleza langempela lincane (isb., ukugeleza okuphakathi epayipini le-DN200 kufana nomthamo we-flowmeter ye-DN100), kuyadingeka ukusebenzisa i-flowmeter enomklamo we-bore oncishisiwe ngemuva kokubala ukuze kwandiswe ijubane loketshezi libe ngaphakathi kwebanga lokusebenza elijwayelekile le-vortex flowmeter.
Izakhiwo Eziphakathi
- Isimo Sesigaba:Ama-Vortex flowmeter angasetshenziswa kuphela ukukala uketshezi lwesigaba esisodwa. Gwema ukusetshenziswa lapho i-medium ingase idlule ekushintsheni kwesigaba ngaphansi kwesimo sokusebenza.
- Izinga lokushisa/Ingcindezi:Izinga lokushisa kanye nokucindezela kwe-medium kunquma ukukhethwa kwengxenye (isb., izinga lokushisa le-sensor ye-piezoelectric) kanye nezinga lokucindezela komzimba. Uma izimo zidlula ububanzi obujwayelekile, kufanele kukhethwe amamodeli okushisa okuphezulu noma okucindezela okuphezulu.
- Ukugqwala:Ukuthi i-medium iyayigqwala yini impahla yepayipi kunquma impahla yomzimba we-flowmeter kanye ne-liner (SS304/316L, i-Hastelloy alloy, i-Titanium, njll.).
- Ukujiya:Ama-Vortex flowmeters azwela kakhulu ekuqineni koketshezi. Ukuqineka ngokweqile kungaholela enanini eliphansi likaReynolds, okungase kuvimbele ukugeleza ukuthi kungangeni esimweni esiguquguqukayo (lapho ukuchitheka kwe-vortex kuba okungazinzile), ngaleyo ndlela kuvimbele ukusebenza okuvamile.
- Ijubane Lokugeleza:Ububanzi bejubane lokugeleza kwe-vortex flowmeter kumele bunqunywe ngokucabangela uhlobo oluphakathi (igesi/uketshezi), izici eziphakathi (ukujiya, ubuningi) kanye nesakhiwo sethuluzi. Isimiso esiyinhloko ukuqinisekisa ukukhiqizwa kwe-vortex okuzinzile ngaphandle kokulimaza ithuluzi noma amapayipi.
Ukufakwa
Ama-Vortex flowmeters azwela kakhulu ezimweni zokufakwa. Ukuqinisekisa ukuthi amapayipi ahamba ngendlela eqondile nokuqeda ukuphazamiseka kubalulekile.
Ukugijima Kwepayipi Eliqondile:Ubude bokugijima kwepayipi eliqondile yikona okubalulekile ekufakweni kwe-vortex flowmeter. Izingxenye ezingenhla komfula njengezindololwane, amavalvu, noma amaphampu zingadala ama-eddies aphazamisa iphrofayili evamile yejubane lokugeleza. Ngokuvamile, kudingeka ukugijima okuqondile okuphansi komfula okuphindwe ka-15 ububanzi bepayipi (15D) yethuluzi kanye nokugijima okuqondile okuphansi okungu-5D. Uma kukhona ivalvu yokulawula evulekile kancane emlanjeni noma izindololwane ezimbili endaweni ehlukile, ukugijima okuqondile okudingekayo kunganda kufike ku-40D noma ngaphezulu ukuqinisekisa ukugeleza okuzinzile.
Isiqondiso Sokufaka:Umcibisholo osendlini ye-flowmeter kumele ulandelwe ngokuqinile ngesikhathi sokufakwa ukuqinisekisa ukuthi uhambisana nesiqondiso sokugeleza koketshezi. Lapho ulinganisa uketshezi, imitha kufanele ifakwe endaweni ephansi ohlelweni lwamapayipi ukuvimbela ukubhajwa kwegesi epayipini lokulinganisa. Lapho ulinganisa amagesi, kufanele ifakwe endaweni ephezulu ukugwema ukunqwabelana koketshezi. Ukuze kufakwe ngokuqondile nge-liquid medium, ukugeleza kufanele kube phezulu ukuze kuqinisekiswe ukuthi ipayipi lihlala ligcwele ngokugcwele ngesikhathi sokusebenza.
Ukuphazamiseka Kokuzivikela:Indawo yokufaka kufanele igcinwe kude namasimu anamandla kazibuthe kanye nezindawo ezinokudlidliza okuphezulu (njengeziguquli kanye nezindawo zokufaka amaphampu). Uma ukudlidliza kubalulekile, kufanele kusetshenziswe izinyathelo zokudambisa, njengokufaka izikhonkwane zamaphayiphi kuma-2D phezulu naphansi kanye nama-anti-vibration pads. Ngesikhathi sokufaka, kubalulekile ukuqinisekisa ukuthi i-flowmeter bore ihambisana kahle nobubanzi bangaphakathi bephayiphi. Ama-gasket akumelwe avele ngaphakathi kwephayiphi, njengoba lokhu kungadala ukuphazamiseka kokugeleza futhi kuholele emaphutheni okulinganisa.
Inzuzo yama-vortex flowmeters isekusetshenzisweni kwawo kuzo zonke izinhlobo zoketshezi kanye nesilinganiso esiphezulu sezindleko nokusebenza, edlala indima engenakuphikwa ekusetshenzisweni kokulinganisa umusi, igesi, kanye noketshezi. Kodwa-ke, kumele kuqondwe ngokucacile ukuthi awayona ithuluzi elijwayelekile "lokuxhuma nokudlala" kodwa kunalokho ayidivayisi enembile ezwela kakhulu ezimweni zoketshezi, ukumiswa kwamapayipi, kanye nendawo yokufaka. Izinkinga eziningi zokusebenza ezihlangatshezwana nazo ngama-vortex flowmeters ekusebenzeni zingavame ukulandelwa emuva ekuhluleleni okungalungile ngesikhathi sesigaba sokukhetha noma ukunganaki imininingwane ngesikhathi sokufakwa endaweni. Ngakho-ke, lapho kusetshenziswa ama-vortex flowmeters, kufanele kuthathwe indlela yobunjiniyela bezinhlelo, iwahlanganise kumjikelezo wepayipi lonke ukuze kucatshangelwe kabanzi. Ukunaka kakhulu amaphuzu abalulekile okukhulunywe ngawo ngenhla kubalulekile ekuqinisekiseni ukuzinza kwenqubo.
Njengomuntuonolwaziithuluziumenzi kanye nomhlinzeki,Shanghai Wangyuanubelokhu ehileleke kakhulu embonini ye-amashumi eminyaka, siqoqa ulwazi olubanzi lokusebenza kwensimu olusebenzayo kanye namakhono okuxazulula izinkinga asebenzayo. Sizibophezele ekuhlinzekeni amakhasimende ngemikhiqizo equkethe ukusebenza okuzinzile kanye nekhwalithi ethembekile, kanye nokusekelwa kobuchwepheshe obuchwepheshile nokwesikhathi. Uma unezidingo eziphathelenei-flowmeterukukhetha noma uhlelo lokusebenza, sicela ukhululekeXhumana nathiukuze uthole ikhambi elenzelwe wena.
