1. Incazelo
Imitha yokugeleza kwe-turbine iyithuluzi lokulinganisa ukugeleza kohlobo lwejubane elinembile kakhulu elilinganisa izinga lokugeleza koketshezi ngokuguqula ijubane lokujikeleza kwe-turbine rotor libe amasignali kagesi. Isetshenziswa kabanzi emikhakheni yezimboni neyezentengiselwano ngenxa yokunemba kwayo okuhle kakhulu kanye nokusabela okusheshayo, ikakhulukazi okufanelekela ukulinganisa uketshezi namagesi ahlanzekile, ane-viscosity ephansi.
2. Isimiso Sokusebenza
Uma uketshezi olulinganisiwe lugeleza emzimbeni wemitha, luqhuba i-turbine rotor ukuthi ijikeleze ngesivinini esilingana nesivinini soketshezi. Ukujikeleza kwe-rotor kunciphisa insimu yamagnetic ekhiqizwa yi-magnet ehlala njalo noma i-electromagnetic coil eyakhelwe ngaphakathi, okubangela isignali ye-electromagnetic pulse enamandla kakhulu ku-sensor. Isignali bese icutshungulwa yi-converter, ebala izinga lokugeleza okusheshayo kanye nokugeleza okuqongelelekayo ngokusekelwe ku-pulse frequency (kulinganiswa kusengaphambili ngokuya nge-flow coefficient yemitha).
3. Izici Eziyinhloko
- Ukunemba Okuphezulu Kokulinganisa: Ekulinganisweni koketshezi, ikilasi lokunemba lingafinyelela ku-±0.1%FS – ±0.5%FS; ekulinganisweni kwegesi, liyi-±1.0%FS – ±1.5%FS. Linokuphindaphindeka okuhle kakhulu (±0.05% – ±0.1%), lihlangabezana nezidingo zokulinganisa ezinembile kakhulu zezinqubo zezimboni.
- Isivinini Sokuphendula Okusheshayo: I-turbine rotor ine-inertia ephansi, evumela impendulo esheshayo ezinguqukweni zesilinganiso sokugeleza koketshezi (isikhathi sempendulo < 10ms). Ilungele izimo zokulinganisa ukugeleza okuguquguqukayo lapho amazinga okugeleza eshintshashintsha njalo.
- Ibanga Lokugeleza Elibanzi kanye nama-Caliber Aguquguqukayo: Isilinganiso sebanga lokugeleza (isilinganiso sokushintsha) singafinyelela ku-1:10 kuya ku-1:30, simboze ububanzi bokugeleza. Ama-caliber ajwayelekile asukela ku-DN4 kuya ku-DN200, anamamodeli amakhulu aklanyelwe wena (kufika ku-DN500) atholakalayo ezinhlotsheni zezimboni zokugeleza okukhulu.
- Isakhiwo Esincane Nokufakwa Okulula: Umzimba wemitha uklanywe ngesakhiwo esilula, esincane ngobukhulu futhi silula ngesisindo. Usekela izindlela eziningi zokufaka ezifana nokuxhumeka kwe-flange, intambo, kanye ne-clamp-on, okuzivumelanisa nezakhiwo ezahlukene zamapayipi.
- Ukulahlekelwa Umfutho Ophansi: Indlela yokugeleza kwangaphakathi yenzelwe ukunciphisa ukumelana noketshezi, kunciphisa ukusetshenziswa kwamandla kohlelo lwamapayipi. Ifaneleka kakhulu kumaphrojekthi agxile ekongeni amandla.
4. Izimo Ezifanele Zoketshezi Nezokusetshenziswa
- Uketshezi: Imikhiqizo kaphethiloli ehlanzekile (uphethiloli, udizili, uphalafini), uwoyela wamaminerali, izinyibilikisi zamakhemikhali, amanzi ahlanzekile, amanzi ompompi, kanye nezinye izinto ezinciphile (≤50mm²/s) kanye nezinto ezingaboli/eziboli kalula.
- Amagesi: Igesi yemvelo, umoya ocindezelwe, i-nitrogen, umoya-mpilo, kanye namanye amagesi omile, ahlanzekile (angenazo izinhlayiya eziqinile kanye nama-condensate).
- Izinkambu Eziyinhloko Zokusebenza: Uphethiloli kanye ne-petrochemical, imboni yamakhemikhali, ukwelashwa kwamanzi, ukudla neziphuzo, ukukhiqizwa kukagesi, izimoto, kanye nezindiza. Iphinde isetshenziswe kabanzi ekulinganisweni kwezentengiselwano (isb., eziteshini zokugcwalisa uphethiloli) kanye nokulawulwa kwezinqubo zezimboni.
5. Izitifiketi Zamazwe Ngamazwe Nezinketho Zezinto Ezibalulekile
- Izitifiketi: Zihambisana nezindinganiso zomhlaba wonke ezifana ne-ISO 9001, CE, ATEX (engaqhumi), UL (eNyakatho Melika), kanye ne-PED (Pressure Equipment Directive, EU), okuqinisekisa ukufinyelela emakethe ezifundeni zomhlaba wonke.
- Ukukhethwa Kwezinto: Umzimba wemitha utholakala ngensimbi engagqwali engu-316L, insimbi yekhabhoni, kanye neHastelloy; i-turbine rotor yenziwe nge-titanium alloy, i-PEEK, noma i-ceramic, evumelana nezidingo ezahlukene zokubola koketshezi kanye nokushisa.
