Mfundo Zosankhira Zoyenera Pazida za Mafani a Centrifugal Otentha Kwambiri
Zinthu zazikuluzikulu za mafani a centrifugal okwera kwambiri zimatengera kutentha. Kutentha kosiyana kumayenderana ndi zida zosiyanasiyana, kapangidwe kake, ndi njira zosindikizira. M'munsimu muli zosankha zachindunji pamtundu uliwonse wa kutentha, ndipo mukhoza kuwatchula mwachindunji kuti mugwiritse ntchito.
1. Kutentha kwabwino mpaka 80℃
Zida zodziwika bwino za mafani a centrifugal otentha kwambiri: Q235, Q355 (A3 chitsulo, 16Mn)
Ntchito: General mpweya wabwino, boiler blower G4-73, mpweya wokwanira
Zofunika: Mtengo wotsika, mphamvu zokwanira, osafunikira chithandizo cha kutentha
2.80 ℃ mpaka 200 ℃
Zida wamba: Q355 (16Mn), 15CrMo
Ntchito: Kuzungulira kwa mpweya wotentha, mzere wowumitsa, kukopera kwa boiler
Mawonekedwe: Kuchita bwino kwa kutentha kumayenda bwino, sikumakonda mapindikidwe
3.200℃ mpaka 350℃
Zida zodziwika bwino za mafani otentha kwambiri a centrifugal: 15CrMo, 12Cr1MoV
Ntchito: Boiler draft fan Y4-73, ng'anjo yamoto, mpweya wotentha kwambiri
Zigawo: Chitsulo chapadera chosamva kutentha, mphamvu yokhazikika yotentha kwambiri
4.350℃ mpaka 600℃
Zida zodziwika bwino za mafani a centrifugal: 304 (0Cr18Ni9), 321, 316L
Ntchito: Chemical mkulu-kutentha mpweya mpweya, incinerator, mkulu-kutentha mpweya wotentha
Mawonekedwe: Chitsulo chosapanga dzimbiri chokhala ndi kukana bwino kwa okosijeni komanso kukana dzimbiri
5.600℃ mpaka 900℃
Zida wamba: 310S (2520), GH3030/GH3044 aloyi kutentha kwambiri
Ntchito: ng'anjo zachitsulo, ng'anjo zozungulira, zida zoyatsira kutentha kwambiri
Zofunika: Ultra-mkulu kutentha makutidwe ndi okosijeni kukana, mtengo wapamwamba
2. Kusankhidwa kwa zida zosiyanasiyana za mafani a centrifugal otentha kwambiri (makina onse ofananira)
Blade: Kutentha kokwera, ndikofunikira kwambiri kusankha chitsulo chosagwira kutentha / chitsulo chosapanga dzimbiri, ndikuchita bwino + chithandizo cha kutentha.
Casing: Chofanana ndi kalasi ya kutentha kwa tsamba, ikhoza kutsika pang'ono giredi imodzi
Shaft: Pazigawo zotentha kwambiri, 40Cr, 42CrMo, 15CrMo ziyenera kukhala patsogolo
Bokosi lonyamula: Zigawo zotentha zanthawi zonse, Q235 ndiyokwanira, mafani otenthetsera kwambiri ayenera kukhala ndi jekete yoziziritsira madzi.
Zigawo zosindikizira:
≤250 ℃: kulongedza kwa asibesitosi, fluororubber
> 250 ℃: chitsulo labyrinth chisindikizo, carbon mphete chisindikizo
3. Kusankhidwa kowonjezera kwa malo owonongeka a mafani a centrifugal otentha kwambiri
Acid ndi alkali-wokhala ndi flue mpweya: 316L> 304> carbon steel
Muli ayoni kloridi: kuletsa mwamphamvu 304, ayenera kukhala 316L/2205 duplex zitsulo
Kuphulika kwafumbi kwakukulu: onjezani zinsalu zosavala, zomangira zosavala za ceramic
4. Mfundo zazikuluzikulu zomwe muyenera kuziganizira posankha mafani a centrifugal kutentha kwambiri
Kutentha> 200 ℃: ayenera kugwiritsa ntchito madzi utakhazikika bokosi
Kutentha> 300 ℃: kuwonjezera kutentha kutchinjiriza shaft manja, kukulitsa olowa
Tsamba lachitsulo chosapanga dzimbiri: liyenera kulandira chithandizo cholimba kuti chiteteze kupindika ndi kusweka
