Ke koho ʻana i ka pono Nāʻano'ōhuna ʻaʻole pili i ka hoʻohālikelike ʻana i kahi helu catalog i kahi papa inoa. E pili ana ia i ka hoʻoponopono ʻana i kahi pilikia maoli—ka hoʻoneʻe ʻana i ka ea e kūʻē i ke kūʻē ʻana, ka mālama ʻana i nā uahi ʻino, ke ola ʻana i nā kahawai 200 ° C, a i ʻole ka mālama ʻana i kahi lua lanahu ma lalo o nā kūlana pahū. Ua nui mākou, hoʻāʻo, a kauoha ʻia ma luna o 1,200 centrifugal fans mai 2020-a i kēlā me kēia hihia, ʻo ke ʻano hewa i hoʻokau i ka lohi, palekana palekana, a i ʻole ka hāʻule mua ʻana.
No ke aha i ʻoi aku ai ka "Type" ma mua o ka nui a i ʻole ka wikiwiki
ʻO ka 9-19 kiʻekiʻe-press centrifugal blower hoʻoneʻe ʻokoʻa i ka ea ma mua o ka lua-inlet centrifugal fan—ʻoiai ma ka RPM like a me ke kaomi paʻa. Aia ka ʻokoʻa ma ka impeller geometry, casing design, a me ke ala ea. ʻO nā impellers i hoʻopaʻa ʻia i hope e mālama i ke kinoea pahu lepo me ka ʻole o ka pipili. Hāʻawi nā ʻāpana ʻāwili i mua i ka leo kiʻekiʻe ma ke kaomi haʻahaʻa haʻahaʻa—akā hāʻule wikiwiki i nā kaiapuni abrasive. Noho ʻo Radial-tip impellers ma waena o lākou: kūpono kūpono, hoʻomanawanui kiʻekiʻe no nā particulates, a me ka maʻalahi mechanical e pili ana i ka mālama ʻana i nā kahua kiln mamao.
Ua hoʻololi mākou i ka peʻahi i hoʻoheheʻe ʻia i mua i kahi laina hoʻoluʻu lole me kahi kumu hoʻohālike i hope. He 4 mahina ka lōʻihi o ka ʻāpana kumu. Ua holo ka mea hou i 37 mahina—ʻaʻohe pani pani, ʻaʻohe paheʻe kāʻei, ʻaʻohe hāʻule ea. No ke aha mai? No ka mea ua koi ka palapala noi i ka haunaele haʻahaʻa, ʻaʻole ka CFM kiʻekiʻe. ʻO ia ke kānāwai mua: hoʻohālikelike i ka ʻano ʻano i ka ʻano ea, ʻaʻole wale i ka pakuhi duct.
ʻO nā ʻano peʻahi Centrifugal ʻEhā—A i kahi e hāʻule ai
ʻAʻole pono nā mea hoʻohana ʻoihana i nā ʻāpana kula. Pono lākou i ka loiloi hoʻoholo. Eia ka mea e hana ai—a kahi e haki ai kēlā me kēia ʻano:
- ʻO nā mea pā i hope-curved (BC).: He mea maikaʻi loa no ka lawelawe ʻana i ka wela kiʻekiʻe, ka wela kiʻekiʻe, a i ʻole ka hana ʻino—e like me nā pūʻulu desulfurization a i ʻole ka ea mua o ka paila. ʻAʻe ka ʻaoʻao impeller mai ka hoʻololi ʻana. Piʻi ka maikaʻi ma 82-87%. Akā, koi lākou i ka hoʻonohonoho pololei ʻana; ʻO ka ductwork misalignned ke kumu o ka haʻalulu e haki ana i nā hale. ʻO kā mākou mau hiʻohiʻona BC (e laʻa, nā ʻano anti-corrosion me nā casings FRP-coated) me nā cones inlet laser-aligned ma ke ʻano maʻamau.
- ʻO nā mea pā ʻāpiʻi i mua (FC).: Paʻa, mālie, a me ka leo kiʻekiʻe ma ka haʻahaʻa haʻahaʻa—kūpono no ka HVAC make-up ea a i ʻole ka lumi hoʻomaʻemaʻe. Akā, kū mālie lākou ma luna o 150 Pa static pressure. Ua ʻike mākou i ʻekolu mau ʻāpana FC i hāʻule i loko o nā laina hoʻolaʻa solvent mea kanu kemika no ka mea ʻaʻole i nānā nā mea hana i ka pihi piʻi piʻi. ʻAʻole lākou i kūkulu ʻia no ka pale ʻana.
- ʻO nā mea pā Radial-tip (RT).: O na lio hana o ka lepo lepo, humu, a i ole ia, a me ka hana abrasive haahaa—ka eli eli, ka hooluolu o ka hale hana, ka pauku kiln rotary. Holo pololei nā lau i waho, e kū'ē ana i ke kūkulu ʻana. Kūʻai ʻia ka pono kiʻekiʻe haʻahaʻa (72-78%) no ka hilinaʻi. I loko o kahi noi hoʻoluʻu sinter a ka mea kūʻai aku metala, ua ʻoki ka poʻe RT i ka manawa hoʻohaʻahaʻa ʻole i hoʻolālā ʻia e 63% ma mua o nā koho BC.
- Nā pā centrifugal lua-inlet: Elua mau impeller ma kekahi kumu, e huki ana i ka ea mai na aoao elua. Hāʻawi i ke kahe kaulike me ka ʻole asymmetry duct. He mea koʻikoʻi inā paʻa ka lewa akā pono e paʻa ke kahe o ka ea—e like me nā puka puka makani a i ʻole nā pūnaewele uahi i kau ʻia ma luna. Eia nō naʻe, pono lākou i ke kau ʻana i ke kumu paʻa. ʻO ka hoʻololi kumu 2 mm i hoʻoulu i ka resonance i kahi papahana hou a hiki i kā mākou hoʻohui ʻana i nā pale heleuma pale pale.
ʻO ka mea a ka Catalog e haʻi ʻole iā ʻoe
Hiki i kekahi ke hoʻopaʻapaʻa ʻoi aku ka maikaʻi o ke koho ʻana i ke ʻano impeller. Akā ua ʻike mākou i nā mea pā titanium me ka pale ʻana i ka corrosion maikaʻi ʻole no ka mea ʻaʻole hiki i ka impeller i hope-curved ke mālama i ka hoʻouka lehu lele. ʻAno wehewehe i ka physics. Hōʻike ka mea i ka puka makani ola.
ʻEkolu mau ʻoiaʻiʻo paʻakikī mai ka ʻikepili kahua:
- Ke moe nei nā pihi kaomi. Manaʻo ka mea peʻahi i helu ʻia no "12 kPa @ 25,000 m³/h" i nā kūlana inlet kūpono. ʻO nā kuʻekuʻe kuʻekuʻe, nā dampers, a me nā kānana e hāʻule i ka hana maoli ma 12-18%. E hoʻāʻo mau ma ka pae ʻōnaehana—ʻaʻole wale ka peʻahi wale nō.
- ʻO ka hōʻoia hōʻoia ʻana i ka pahū (e laʻa, dⅠ no nā mine lanahu) pili i ka hui piha—ʻaʻole i ke kaʻa wale nō. ʻO kahi kaʻa kaʻa i hoʻopaʻa ʻia i hoʻopaʻa ʻia i kahi hale ʻaʻole i hōʻoia ʻia ʻaʻole ia e hoʻokō. ʻO kā mākou hui pūʻulu FBD e loaʻa i nā ʻae impeller kūʻē i ka spark-resistant a me nā ala static grounded i hōʻoia ʻia no GB 3836.1.
- ʻAʻole koho ʻia ke kaupaona ʻana. ʻO nā mea pā BC kaulike ʻole e haʻalulu ma 1,450 RPM. Ma 2,900 RPM, hoʻonui ʻia kēlā ʻano like ʻole i ka ikaika ʻehā. Loaʻa kēlā me kēia Hongcheng centrifugal fan i ke kaulike ISO 1940 G2.5—ana ʻia, ʻaʻole i manaʻo ʻia.
Pehea e koho ai—He Papa Hooia Mahele Elima Minute
Ma mua o kou wehe ʻana i kahi pepa kikoʻī, e pane i kēia mau nīnau ʻelima:
- He aha ka piʻi paʻa paʻa kiʻekiʻe—ʻaʻole kiʻekiʻe, ʻaʻole theoretical? E ana me ka manometer ma ka puka makani, ma lalo o ka haawe piha.
- Aia i loko o ke kahawai abrasives, moisture, a kemika paha? Inā ʻae, e hoʻopau i ka ʻāwili i mua. E koho mua i ka radial-tip a i ʻole i hope-curved me nā uhi pale.
- ʻO kaohi ʻia ka lewa? Mālama ʻo Dual-inlet i ka wāwae akā koi i ka rigidity structural. ʻOi aku ka maʻalahi o ka puka komo hoʻokahi me ka cone komo lōʻihi.
- E hoʻololi pinepine nā mea hoʻohana i ke kahe? ʻOi aku ka maikaʻi o ka hoʻopaʻa ʻana o nā lima i hope. Ke piʻi ʻole nei ka piʻi ʻana i mua ma lalo o 60% ka wikiwiki.
- He aha ka koina hemahema? He $18,000 / hola ke pani ʻia ma ka hale paila. E uku i mua no ka nānā ʻana i ka wela i hope-curved + hoʻohui ʻia—ʻaʻole ma hope no ka hoʻoponopono ulia pōpilikia.
ʻAʻole hiki ke hoʻololi ʻia nā ʻano peʻahi Centrifugal. He mau pane ʻenehana lākou i nā kaohi kino. E koho i ke ʻano e mahalo ai i kou ea, kou kaiapuni, a me kāu mau pahuhopu i ka wā o ka wā hana—ʻaʻole ka mea me ka palapala ʻālohilohi loa.
