Zoyezera kuyenda kwa vortexZimagwira ntchito motsatira mfundo ya msewu wa Kármán vortex. Chifukwa cha mawonekedwe awo monga kulondola kwambiri, chiŵerengero cha kugwedezeka kwakukulu, komanso kusakhala ndi ziwalo zosuntha, ma vortex flowmeter amagwiritsidwa ntchito kwambiri poyesa kuyenda kwa nthunzi, mpweya, ndi madzi. Komabe, zida izi zimakhala zovuta kwambiri pakuyenda kwa madzi, ndipo magwiridwe antchito awo apamwamba sangakwaniritsidwe mokwanira pansi pa mikhalidwe yonse yogwirira ntchito. Ngati palibe kumvetsetsa kwakuya kwa momwe zinthu zilili kapena kusayang'anira mokwanira tsatanetsatane wa malo oyika, chida cholondola ichi chingakumane mosavuta ndi mavuto monga kuwerenga kosazolowereka, zolakwika zambiri, ndi ma alamu obwerezabwereza. Chifukwa chake, kuyambira kusankha chitsanzo mpaka kukhazikitsa, kukhazikika kwa magwiridwe antchito pagawo lililonse ndikofunikira kuti zitsimikizire kuti vortex flowmeter ikugwira ntchito bwino.
Kusankha chitsanzo
Kusintha njira yosankhidwiratu kuti igwirizane ndi ntchito inayake ndikofunikira kwambiri kuti muyese molondola. Njira yosankhidwiratu iyenera kuyang'ana kwambiri pakugwirizana kolondola kwa zinthu zitatu zazikulu: kuchuluka kwa madzi, kukula kwa chitoliro ndi mawonekedwe apakati, kuti mupewe mavuto omwe amabwera chifukwa cha kusankha kosayenera komwe kungafunike kusintha kwina.
Kufananiza Ma Range:Kuchuluka kwa kayendedwe ka ntchito kuyenera kugwera mkati mwa 20% mpaka 80% ya kuchuluka kwa chipangizocho. Ngati kuchuluka kwa kayendedwe ka madzi kukutsika pansi pa 20%, chizindikiro cha vortex chimakhala chofooka ndipo chinganyalanyazidwe chifukwa cha kuchepa kwa ntchito yochepetsa kayendedwe ka madzi (zomwe zimapangitsa kuti mayendedwe azitha kuwerengedwa ndi 0). Ngati chapitirira 80%, chingapitirire malire a sensor tolerance apamwamba (monga kuwonongeka kwa masensa a piezoelectric).
Kufananiza kwa DN:Chitoliro cha ortex flowmeter chiyenera kufanana ndi kukula kwa chitoliro cha process kuti tipewe kusokonezeka kwa kayendedwe ka madzi komwe kumachitika chifukwa cha kusiyana kwa kukula kwa DN. Komabe, m'mikhalidwe yomwe chitoliro cha processing chili chachikulu koma kuchuluka kwenikweni kwa madzi kumakhala kochepa (monga, kuyenda kwapakati mu chitoliro cha DN200 kumafanana ndi mphamvu ya DN100 flowmeter), ndikofunikira kugwiritsa ntchito flowmeter yokhala ndi kapangidwe kocheperako ka bore pambuyo powerengera kuti muwonjezere liwiro la madzi mkati mwa nthawi yogwira ntchito ya vortex flowmeter.
Katundu Wapakati
- Gawo la Gawo:Ma Vortex flowmeters angagwiritsidwe ntchito poyesa madzi a gawo limodzi lokha. Pewani kugwiritsa ntchito pamene cholumikiziracho chingasinthe gawolo pamene chikugwira ntchito.
- Kutentha/Kupanikizika:Kutentha ndi kupanikizika kwa chipangizocho ndizomwe zimasankha gawo (monga kutentha kwa sensa ya piezoelectric) ndi kupsinjika kwa thupi. Ngati zinthu zipitirira muyezo wokhazikika, mitundu ya kutentha kwambiri kapena kupanikizika kwakukulu iyenera kusankhidwa.
- Kuwononga:Kaya sing'angayo imawononga zinthu za chitolirocho ndiye kuti imatsimikizira zinthu za thupi la flowmeter ndi liner (SS304/316L, Hastelloy alloy, Titanium, ndi zina zotero).
- Kukhuthala:Ma vortex flowmeters amakhudzidwa kwambiri ndi kukhuthala kwa madzi. Kukhuthala kochulukirapo kungayambitse chiwerengero chochepa cha Reynolds, zomwe zingalepheretse kuyenda kwa madzi kulowa mu mkhalidwe wovuta (kumene kutayika kwa vortex kumakhala kosakhazikika), motero kulepheretsa kugwira ntchito bwino.
- Liwiro la Kuyenda:Kuthamanga kwa vortex flowmeter kuyenera kudziwika poganizira mtundu wapakati (gasi/madzimadzi), makhalidwe apakati (kukhuthala, kuchulukana) ndi kapangidwe ka chipangizocho. Mfundo yaikulu ndikuwonetsetsa kuti vortex imapanga bwino popanda kuwononga chipangizocho kapena mapaipi.
Kukhazikitsa
Ma Vortex flowmeters ndi osavuta kugwiritsa ntchito pakakhala vuto la kuyika. Kuonetsetsa kuti mapaipi akuyenda molunjika komanso kuchotsa kusokoneza ndikofunikira kwambiri.
Kuthamanga kwa Chitoliro Cholunjika:Kutalika kwa kuyenda kwa mapaipi molunjika ndiye chinthu chofunikira kwambiri poika vortex flowmeter. Zinthu zakumtunda monga zigongono, ma valve, kapena mapampu zimatha kupanga ma eddies omwe amasokoneza liwiro la kuyenda kwa madzi. Nthawi zambiri, kuyenda kolunjika kocheperako kopitilira 15 kuposa kukula kwa chitoliro (15D) cha chida ndi kuthamanga kolunjika kotsika kwa 5D ndikofunikira. Ngati pali valavu yowongolera yotseguka pang'ono pamwamba kapena zigongono ziwiri m'njira yosiyana, kuthamanga kolunjika kofunikira kumatha kuwonjezeka kufika pa 40D kapena kuposerapo kuti zitsimikizire kuyenda kokhazikika.
Malangizo Okhazikitsa:Muvi womwe uli pa chipinda choyezera madzi uyenera kutsatiridwa mosamala poika kuti ugwirizane ndi njira yoyezera madzi. Poyezera madzi, mita iyenera kuyikidwa pamalo otsika mu dongosolo la mapaipi kuti mpweya usatseke mu chubu choyezera. Poyezera mpweya, iyenera kuyikidwa pamalo okwera kuti madzi asasonkhanitsidwe. Poika choyimirira ndi madzi, madzi ayenera kukwera mmwamba kuti chitolirocho chikhalebe chodzaza mokwanira panthawi yogwira ntchito.
Chitetezo chamthupi Chosokoneza:Malo oyikapo ayenera kusungidwa kutali ndi mphamvu zamaginito amphamvu komanso malo omwe amagwedezeka kwambiri (monga ma transformer ndi malo otulutsira mapampu). Ngati kugwedezeka kuli kwakukulu, njira zochepetsera chinyezi ziyenera kukhazikitsidwa, monga kukhazikitsa zomangira mapaipi pa 2D mmwamba ndi pansi komanso ma pads oletsa kugwedezeka. Pakuyikapo, ndikofunikira kuonetsetsa kuti chibowo cha flowmeter chikugwirizana ndi m'mimba mwake wamkati wa chitoliro. Ma gasket sayenera kutuluka mkati mwa chitoliro, chifukwa izi zingayambitse kusokonezeka kwa kayendedwe ka madzi ndikupangitsa zolakwika pakuyeza.
Ubwino wa ma vortex flowmeters uli mu kugwiritsidwa ntchito kwawo m'mitundu yosiyanasiyana yamadzimadzi komanso chiŵerengero cha mtengo ndi magwiridwe antchito apamwamba, zomwe zimagwira ntchito yofunika kwambiri poyesa nthunzi, gasi, ndi madzi. Komabe, ziyenera kumveka bwino kuti si chida cha "plug-and-play" chapadziko lonse lapansi koma ndi chipangizo cholondola chomwe chimakhudzidwa kwambiri ndi madzimadzi, mapangidwe a mapaipi, ndi malo oyika. Mavuto ambiri ogwirira ntchito omwe amakumana nawo ndi ma vortex flowmeters nthawi zambiri amatha kutsatiridwa ndi kusaganizira bwino panthawi yosankha kapena kunyalanyaza tsatanetsatane panthawi yoyika pamalopo. Chifukwa chake, mukamagwiritsa ntchito ma vortex flowmeters, njira yogwiritsira ntchito makina iyenera kutsatiridwa, kuwaphatikiza mu circuit yonse ya mapaipi kuti aganizidwe mokwanira. Kuyang'anitsitsa mfundo zazikulu zomwe zatchulidwa pamwambapa ndikofunikira kuti muwonetsetse kuti njirayo ndi yokhazikika.
Mongawodziwa zambirichidawopanga ndi wogulitsa,Shanghai Wangyuanwakhala akugwira ntchito kwambiri mumakampaniwazaka makumi ambiri, kupeza chidziwitso chambiri chogwiritsa ntchito njira zogwirira ntchito komanso luso lotha kuthetsa mavuto. Tadzipereka kupatsa makasitomala zinthu zomwe zimagwira ntchito bwino komanso zabwino, komanso chithandizo chaukadaulo chaukadaulo chaukadaulo komanso cha panthawi yake. Ngati muli ndi zofunikira zokhudzana ndi izi,choyezera kayendedwe ka madzikusankha kapena kugwiritsa ntchito, chonde musazengerezeLumikizanani nafekuti mupeze yankho lokonzedwa bwino.
