Noonoo Koho Kupono no na Lako o Kiekie-Mahana Centrifugal Fans
ʻO ka mea nui o nā mea pā centrifugal kiʻekiʻe e pili ana i ka pae wela. ʻO nā mahana likeʻole e pili ana i nā mea likeʻole, nā hale, a me nā hoʻonā sila. Aia ma lalo iho nā hopena koho pololei loa no kēlā me kēia pae wela, a hiki iā ʻoe ke kuhikuhi pololei iā lākou no ka hoʻohana ʻana.
1. ʻO ka mahana maʻamau i ka 80 ℃
Nā mea maʻamau no nā mea pā centrifugal kiʻekiʻe: Q235, Q355 (A3 kila, 16Mn)
Hoʻohana: ʻO ka ventila maʻamau, ka mea hoʻoheheʻe pahu G4-73, ka lako ea
Nā hiʻohiʻona: ʻO ke kumukūʻai haʻahaʻa, lawa ka ikaika, ʻaʻohe pono no ka mālama wela
2. 80 ℃ i 200 ℃
Mea maʻamau: Q355 (16Mn), 15CrMo
Noi: Ka ea wela, ka laina maloʻo, ka pahu pahu pahu maʻamau
Nā hiʻohiʻona: ʻO ka hana ʻana i ka wela wela maikaʻi, ʻaʻole hiki ke hoʻololi
3. 200 ℃ i 350 ℃
Nā mea maʻamau no nā mea pā centrifugal kiʻekiʻe: 15CrMo, 12Cr1MoV
Noi: ʻO ka mea hoʻoheheʻe pahu pahu Y4-73, ka pauku kiln, ke kinoea puhi wela wela
Nā hiʻohiʻona: Ke kila wela kūʻokoʻa, paʻa ka ikaika wela kiʻekiʻe
4. 350 ℃ a 600 ℃
Nā mea maʻamau no nā mea pā centrifugal kiʻekiʻe: 304 (0Cr18Ni9), 321, 316L
Noi: Kemiea kiʻekiʻe-mehana hoʻopau kinoea, incinerator, kiʻekiʻe-mehana wela ea
Nā hiʻohiʻona: Ke kila kila me ka maikaʻi o ka pale ʻana a me ka pale ʻana i ka corrosion
5. 600 ℃ a 900 ℃
Nā mea maʻamau: 310S (2520), GH3030/GH3044 mau mea wela wela
Noi: Na kapuahi metallurgical, rotary kilns, na mea puhi wela wela
Nā hiʻohiʻona: Ultra-high temperature oxidation resistance, high price
2. Ke koho ʻana i nā mea ʻāpana like ʻole no nā mea pā centrifugal kiʻekiʻe (me ka mīkini holoʻokoʻa)
Blade: ʻOi aku ke kiʻekiʻe o ka mahana, ʻoi aku ka pono e koho i ke kila wela / stainless steel, a hana i ke koena ikaika + mālama wela.
Casing: E like me ka pae wela o ka lau, hiki ke emi iki i hoʻokahi papa
Shaft: No nā ʻāpana wela kiʻekiʻe, 40Cr, 42CrMo, 15CrMo pono e hana mua ʻia.
Ka pahu pahu: ʻO nā ʻāpana wela maʻamau, lawa ka Q235, pono e hoʻolako ʻia nā mea pā wela kiʻekiʻe me ka lole hoʻoluʻu wai.
ʻāpana hoʻopaʻa ʻana:
≤250 ℃: asbestos packing, fluororubber
>250 ℃: sila labyrinth metala, sila apo kalapona
3. Koho hou aku no nā kaiapuni corrosion o nā pā centrifugal wela kiʻekiʻe
ʻAkika a me ke kinoea kinoea alkali: 316L > 304 > kila kalapona
Loaʻa i nā ion chloride: pāpā loa i ka 304, pono ʻo 316L/2205 duplex steel
ʻO ka lepo abrasion kiʻekiʻe: hoʻohui i ka lining hiki ke hoʻopaʻa ʻia, nā ceramics pale ʻaʻahu
4. Nā mea nui e noʻonoʻo ai no ke koho ʻana i ka peʻahi centrifugal kiʻekiʻe
ʻO ka mahana> 200 ℃: pono e hoʻohana i ka pahu pahu hoʻoluʻu wai
ʻO ka wela> 300 ℃: hoʻohui i ka lima hoʻoheheʻe wela, ka hui hoʻonui
ʻO ka ʻili kila kila: pono e hana i ka lāʻau hoʻonā paʻa e pale ai i ka deformation a me ka haki ʻana
