Litlhokomelo tsa Khetho e nepahetseng Bakeng sa Lisebelisoa tsa Fans ea Mocheso o Phahameng oa Centrifugal
Lintho tse ka sehloohong tsa li-fan tsa centrifugal tsa mocheso o phahameng li itšetlehile ka mocheso oa mocheso. Lithempereichara tse fapaneng li lumellana le lisebelisoa tse fapaneng, meaho le tharollo ea ho tiisa. Ka tlase ho na le liqeto tse tobileng ka ho fetisisa tsa khetho bakeng sa mocheso o mong le o mong, 'me u ka bua ka tsona ka ho toba bakeng sa tšebeliso.
1. Mocheso o tlwaelehileng ho fihla ho 80℃
Lisebelisoa tse tloaelehileng bakeng sa libapali tsa centrifugal tsa mocheso o phahameng: Q235, Q355 (A3 steel, 16Mn)
Kopo: Ka kakaretso ventilation, boiler blower G4-73, phepelo conditioning moea
Likarolo: Theko e tlaase, matla a lekaneng, ha ho hlokahale phekolo ea mocheso
2.80℃ ho isa ho 200℃
Lisebelisoa tse tloaelehileng: Q355 (16Mn), 15CrMo
Kopo: Ho potoloha ha moea o chesang, mohala oa ho omisa, moralo o akaretsang oa boiler
Likarolo: Ts'ebetso e ntle ea ho hanyetsa mocheso, e sa rateheng haholo ho deformation
3.200℃ ho isa ho 350℃
Lisebelisoa tse tloaelehileng bakeng sa libapali tsa centrifugal tsa mocheso o phahameng: 15CrMo, 12Cr1MoV
Kopo: Boiler draft fan Y4-73, kilne exhaust, mocheso o phahameng oa khase ea flue
Likarolo: Tšepe e khethehileng e thibelang mocheso, matla a tsitsitseng a mocheso o phahameng
4.350℃ ho isa ho 600℃
Lisebelisoa tse tloaelehileng bakeng sa libapali tsa centrifugal tsa mocheso o phahameng: 304 (0Cr18Ni9), 321, 316L
Kopo: Khase e tsoang ka lik'hemik'hale ea mocheso o phahameng, secheso, moea o chesang oa mocheso o phahameng
Likarolo: Tšepe e sa hloekang e nang le khanyetso e ntle ea oxidation le khanyetso ea kutu
5.600℃ ho isa ho 900℃
Lisebelisoa tse tloaelehileng: 310S (2520), GH3030/GH3044 li-alloys tse phahameng tsa mocheso
Tšebeliso: Libōpi tsa metallurgical, libōpi tse rotary, lisebelisoa tsa ho chesa mocheso o phahameng
Likarolo: Ho hanyetsa oxidation ea mocheso o phahameng haholo, theko e phahameng
2. Khetho ea lisebelisoa tsa likarolo tse fapaneng bakeng sa libapali tsa centrifugal tsa mocheso o phahameng (ho bapisa mochini o felletseng)
Blade: Ha mocheso o phahame, ho hlokahala le ho feta ho khetha tšepe e sa keneleng mocheso / tšepe e sa jeleng paate, le ho etsa botsitso bo matla + kalafo ea mocheso.
Casing: Ho tšoana le boemo ba mocheso oa lehare, e ka ba tlase hanyane sehlopheng se le seng
Shaft: Bakeng sa likarolo tsa mocheso o phahameng, 40Cr, 42CrMo, 15CrMo e lokela ho etelletsoa pele
Lebokose la ho bea: Likarolo tse tloaelehileng tsa mocheso, Q235 e lekane, libapali tsa mocheso o phahameng li tlameha ho hlomelloa ka jekete e pholileng ea metsi.
Likarolo tsa ho tiisa:
≤250 ℃: ho paka asbestos, fluororubber
> 250 ℃: tiiso ea tšepe labyrinth, carbon ring seal
3. Khetho e eketsehileng bakeng sa tikoloho ea kutu ea li-fan tsa centrifugal tsa mocheso o phahameng
Acid le alkali-e nang le flue gase: 316L > 304 > carbon steel
E na le li-ion tsa chloride: thibela ka tieo 304, e tlameha ho ba 316L/2205 duplex steel
Ho phatloha ha lerōle le phahameng: eketsa lesela le sa senyeheng, lirafshoa tse sa aparoeng
4. Lintlha tsa bohlokoa tse lokelang ho nahanoa bakeng sa khetho ea fan ea centrifugal ea mocheso o phahameng
Mocheso> 200 ℃: E tlameha ho sebelisa lebokose le nang le metsi a pholileng
Mocheso> 300 ℃: eketsa letsoho la shaft e kenyang mocheso, lenonyeletso la katoloso
Lehare la tšepe e sa hloekang: le tlameha ho fumana kalafo e tiileng ea tharollo ho thibela deformation le ho peperana
