Iingqwalasela zoKhetho oluLungileyo lweMathiriyeli ye Abalandeli be-Centrifugal bobushushu obuphezulu
Izinto ezingundoqo zabalandeli be-centrifugal eziphezulu zokushisa zixhomekeke kuluhlu lweqondo lokushisa. Amaqondo obushushu ahlukeneyo ahambelana nezixhobo ezahlukeneyo, izakhiwo, kunye nezisombululo zokutywinwa. Apha ngezantsi zezona zigqibo zokukhetha ngokuthe ngqo kuluhlu ngalunye lobushushu, kwaye ungabhekisa kuzo ngokuthe ngqo ukuba zisetyenziswe.
1. Ubushushu obuqhelekileyo ukuya kwi-80℃
Izinto eziqhelekileyo zabalandeli be-centrifugal bobushushu obuphezulu: Q235, Q355 (A3 steel, 16Mn)
Isicelo: I-ventilation ngokubanzi, i-boiler blower G4-73, i-air conditioning supply
Iimpawu: Iindleko eziphantsi, amandla aneleyo, akukho mfuneko yonyango lokushisa
2. 80℃ ukuya kuma-200℃
Izinto eziqhelekileyo: Q355 (16Mn), 15CrMo
Isicelo: Ukujikeleza komoya oshushu, umgca wokumisa, idrafti yebhoyili jikelele
Iimpawu: Ukusebenza kakuhle kokuxhathisa ubushushu, ukuchaneka kancinci kwi-deformation
3. 200℃ ukuya 350℃
Izinto eziqhelekileyo zabalandeli be-centrifugal bobushushu obuphezulu: 15CrMo, 12Cr1MoV
Isicelo: Idrafti ye-Boiler eyi-fan ye-Y4-73, i-kiln exhaust, igesi yobushushu obuphezulu
Iimpawu: Intsimbi ekhethekileyo yokumelana nobushushu, amandla azinzileyo obushushu obuphezulu
4. 350℃ ukuya 600℃
Izinto eziqhelekileyo kubushushu obuphezulu befeni ye-centrifugal: 304 (0Cr18Ni9), 321, 316L
Isicelo: I-Chemical high-temperature exhaust gas, incinerator, i-high-temperature eshushu yomoya
Iimpawu: Insimbi engenasici enokumelana ne-oxidation egqwesileyo kunye nokumelana nomhlwa
5. 600℃ ukuya 900℃
Izinto eziqhelekileyo: 310S (2520), GH3030/GH3044 i-alloys ephezulu yobushushu
Isicelo: Iziko lesinyithi, iitoni ezijikelezayo, izixhobo zokutshisa ezinobushushu obuphezulu.
Iimpawu: Ukumelana ne-oxidation yobushushu obuphezulu, ixabiso eliphezulu
2. Ukukhethwa kwezixhobo zamacandelo ahlukeneyo obushushu obuphezulu be-centrifugal abalandeli (ukuhambelana nomatshini wonke)
I-Blade: Ukuphakama kweqondo lobushushu, kokukhona kuyimfuneko ukukhetha intsimbi enganyangekiyo / intsimbi engenanto, kwaye wenze ibhalansi eguqukayo + unyango lobushushu.
I-Casing: Ngokufanayo nebakala lobushushu be-blade, ingaba ngaphantsi kancinane kwibakala elinye
I-Shaft: Kumacandelo aphezulu obushushu, i-40Cr, i-42CrMo, i-15CrMo kufuneka ibekwe phambili
Ibhokisi yokuthwala: Iindawo zobushushu eziqhelekileyo, i-Q235 yanele, abalandeli bobushushu obuphezulu kufuneka baxhotyiswe ngebhatyi yokupholisa amanzi.
Iindawo zokutywina:
≤250℃: ukupakisha asbestos, fluororubber
> 250 ℃: itywina lelabyrinth yentsimbi, itywina lomsesane wekhabhoni
3. Ukhetho olongezelelweyo lweendawo zokubola kweefeni eziphakamileyo ze-centrifugal
I-Acid kunye ne-alkali-equlethe i-flue gas: 316L> 304> i-carbon steel
Iqulathe ion chloride: ukuthintela ngokungqongqo 304, kufuneka 316L/2205 duplex steel
I-abrasion ephezulu yothuli: yongeza i-lining-resistant lining, i-ceramics ekwazi ukunxiba
4. Amanqaku aphambili ekufuneka aqwalaselwe kukhetho lobushushu obuphezulu be-centrifugal fan
Iqondo lobushushu > 200℃: kufuneka usebenzise ibhokisi yokuthwala epholiswe ngamanzi
Iqondo lobushushu> 300℃: yongeza umkhono weshaft yokugquma ubushushu, ijoyini yokwandiswa
I-Stainless steel blade: kufuneka ifumane unyango lwesisombululo esiluqilima ukuthintela ukuguquka kunye nokuqhekeka
