I. Ukuguqulwa Kohlobo Oluphakathi

1. Izimo Zokusebenza Zoketshezi

• Ifanele uketshezi oluhlanzekile, olune-viscosity ephansi, olunesigaba esisodwa njengamanzi ompompi, amanzi ajikelezayo ezimbonini, uphethiloli, udizili, i-methanol, i-ethanol, kanye ne-ethylene glycol.
• Kudinga inombolo yeReynolds ye-medium ibe yi-Re > 2000 (isilinganiso sokugeleza esiphakathi kuya kwesiphezulu). Imidiya ene-viscosity ephezulu (isb., uwoyela osindayo, uwoyela wokugcoba) kufanele igwenywe, njengoba izobangela ukukhiqizwa kwe-vortex okungazinzile kanye nokuwohloka okukhulu kokunemba.

2. Izimo Zokusebenza Ngegesi

• Ifanele amagesi omile nahlanzekile njengegesi yemvelo, umoya ocindezelwe, i-nitrogen, i-oxygen, i-carbon dioxide, kanye negesi ye-blast furnace (ukungcola kudinga ukuhlungwa).
• Ingahlangabezana nezidingo zokulinganisa amagesi okushisa okujwayelekile kanye namazinga okushisa aphakathi kuya kwaphezulu (isb., ukuqapha igesi yomoya ongcolile). Kufanele kunakwe umfutho wegesi ozinzile ukuze kugwenywe ukushintshashintsha okukhulu okuthinta imiphumela yokulinganisa.

3. Izimo Zokusebenza Nge-Steam

• Lesi yisimo esiwusizo kuma-vortex flowmeters, afaneleka kakhulu ekulinganisweni komusi ogcwele kanye nomusi oshisayo kakhulu, njengomusi webhoyila ezitshalweni zamandla, umusi wokucubungula ezitshalweni zamakhemikhali, kanye nomusi ezihlelweni zokushisa.
• Ingamelana nokushisa okuphezulu kanye nokucindezela okuphezulu (ngokuvamile izinga lokushisa ≤ 400℃, ingcindezi ≤ 16MPa) ngokulahlekelwa yingcindezi ephansi, okunciphisa ukusetshenziswa kwamandla epayipi.

II. Izimo Zokusebenza Zamapayipi Nokufakwa

1. Izidingo Zobubanzi Bepayipi

• Ifanele ububanzi bepayipi obuphakathi kuya kobukhulu obune-DN ≥ 25mm (ngokuvamile i-DN25~DN3000). Ukunemba kokulinganisa ububanzi bepayipi elincane (DN < 25mm) kuphansi futhi akukhuthazwa.
• Isekela ukufakwa okuvundlile, okuqondile, noma okuthambekele, kodwa kuyadingeka ukuqinisekisa ukugeleza kwepayipi eligcwele koketshezi noma ukugeleza okufanayo kwamagesi/umusi ukuze kugwenywe amapayipi angenalutho noma ukugeleza kwegesi-uketshezi kwezigaba ezimbili.

2. Izidingo Zesigaba Sepayipi Eliqondile

• Kumelwe ihlangabezane nezidingo zobude bezingxenye zamapayipi aqondile ngaphambi nangemva kwemitha: ngokuvamile, phezulu ≥ izikhathi eziyi-10 zobubanzi bepayipi kanye naphansi ≥ izikhathi ezi-5 zobubanzi bepayipi (uma kungekho zingxenye zokuphazamiseka). Uma kukhona ama-valve noma izindololwane, ubude besigaba samapayipi aqondile kufanele bukhuliswe (isb., phezulu ≥ izikhathi ezingama-20 zobubanzi bepayipi) ukuqinisekisa insimu yokugeleza koketshezi okuzinzile.

III. Izimo Zokusebenza Zemvelo Nezinqubo

1. Izinga Lokushisa Nokucindezela

• Ibanga lokushisa: -40℃ ~400℃ (amamodeli ajwayelekile); amanye amamodeli okushisa okuphezulu angamelana namazinga okushisa aphezulu (isb., 550℃).
• Ububanzi bokucindezela: 0~16MPa (amamodeli ajwayelekile); amamodeli anomfutho ophezulu angahlangabezana nezimo zokusebenza ngokucindezela okungu-≤ 40MPa (isb., uketshezi olunomfutho ophezulu ezindaweni zikawoyela).

2. Izidingo Zemvelo

• Kufanelekela izindawo zezimboni ezivamile njengezindawo zokusebenzela ze-petrochemical, ugesi, kanye nezensimbi. Uma indawo inokudlidliza okunamandla (isb., eduze kwamaphampu), amadivayisi okunciphisa ukudlidliza kumele afakwe; ngaphandle kwalokho, ukudlidliza kuzophazamisa ukutholwa kwe-vortex futhi kubangele ukuzulazula kwedatha.
• Ingasetshenziswa ezimweni ezingaqhumi (kudingeka izinzwa ezingaqhumi), njengezindawo ezivuthayo neziqhumayo ezindaweni zikawoyela kanye nezitshalo zamakhemikhali.

IV. Ukuzivumelanisa Nezidingo Zokulawula Izinqubo

1. Uhla Lokugeleza

• Inesilinganiso esibanzi sokujika (1:10~1:30), esifanele izimo zokusebenza ezinokuguquguquka okukhulu kokugeleza, njengokulinganiswa kokudla kuma-reactor amakhemikhali kanye nokulinganiswa kokugeleza komusi ngesikhathi sokushintsha komthwalo ezitshalweni zamandla.

2. Ukukhishwa Kwesignali Nokuhlanganiswa

• Isekela imiphumela yesignali efana ne-4-20mA, i-pulse, i-HART, ne-RS485, futhi ingaxhunywa ngqo ezinhlelweni ze-PLC ne-DCS ukuze ihlangabezane nezidingo zokuqapha okude kanye nokulawula okuzenzakalelayo, njengokulawula ukugeleza okuvaliwe emigqeni yokukhiqiza yezimboni.

V. Izimo Zokusebenza Okufanele Zigwenywe

1. Ukuqina okuphezulu (i-kinematic viscosity > 10mm²/s), okuqukethwe okuphezulu okuqinile (okuqukethwe kwezinhlayiya eziqinile > 1%), okukwazi ukukristala kalula, noma okukwazi ukukala kalula.
2. Izinga lokugeleza eliphansi (inombolo kaReynolds Re < 2000) kanye nezimo zobubanzi obuncane (DN < 25mm).
3. Ukugeleza kwegesi-uketshezi okunezigaba ezimbili noma ukugeleza kwezigaba ezimbili okuqinile koketshezi (isb., uketshezi olunamabhamuza, indle equkethe inani elikhulu lokungcola).
4. Izindawo ezinokudlidliza okunamandla noma ukuphazamiseka okukhulu kwe-electromagnetic (ngaphandle kwezindlela zokuzivikela).
