Ke koho ʻana i ka pono Nā Kūlana Axialia ʻaʻole e pili ana i ke koho ʻana i ka ʻāpana leo nui a i ʻole ka nui. E pili ana ia i ka hoʻohālikelike ʻana i ka ea, kaomi, a me ke kūpaʻa ʻana o ke kaiapuni i kāu kaʻina hana - ʻaʻole e hoʻonui i ka hoʻolimalima ʻana i nā kikoʻī i hana ʻia, ʻaʻole hoʻi ma lalo o ka wehewehe ʻana a me ke kū ʻana i ka wā haʻahaʻa, wela nui, a i ʻole palekana palekana. Ua ʻike pinepine mākou: kahi ʻōnaehana hoʻoheheʻe eli ʻana no ka mea ua kuhi hewa ʻia ke kaomi static e 12%; Ua hoʻololi kekahi mea kanu kemika i ʻekolu pā i loko o 18 mahina ma muli o ka ʻino i mālama ʻole ʻia i ke koho ʻana; E lilo ana ka hale paila he 8% ka pono o ka puhi ahi ma hope o ka hoʻokomo ʻana i ka peʻahi axial me ka pitch blade like ʻole a me ka wikiwiki o ka duct.
E hoʻomaka me ka Pūnaehana—ʻAʻole ka Peʻa
Hoʻoneʻe ʻia nā mea hoʻoheheʻe axial flow i ka ea e like me ke kumu. Huna kēlā maʻalahi i ka paʻakikī. E hāʻule koke kā lākou hana i ka wā i hoʻokomo ʻia me ka nānā ʻole ʻana i ka haunaele inlet, ke kū ʻana o ka puka, a i ʻole nā kūlana ambient. Ma mua o kou hoʻohālikelike ʻana iā RPM a i ʻole motor kW, e pane i kēia mau nīnau ʻelima i hōʻoia ʻia:
- He aha ke koi ʻana o ke kaomi static maoli? ʻAʻole ka helu ʻana i nā pihi "ea manuahi" - e ana i ka pale ʻana o ka ʻōnaehana me ka pani ʻana o nā mea hoʻoheheʻe, helu ʻia nā kuʻekuʻe, hoʻouka ʻia nā kānana, a me nā auwai i ka holo ʻana o ka hoʻolālā. ʻO kahi kikoʻī 500 Pa ma ka pepa e lilo pinepine i 720 Pa i ka hana.
- He aha ka liʻiliʻi liʻiliʻi o ka hoʻomau ʻana o ka ea—a he aha ka mahana, ka haʻahaʻa, a me ka haʻahaʻa ʻala? Hoʻokuʻu nā mea pā axial i ka 30-40% mana ma luna o 60°C ke ʻole e helu ʻia nā lau a me nā bearings no ia. I ka lawelawe ʻana i ka lanahu, 20 g/m³ ka hoʻouka ʻana i ka lepo e koi ana i nā bearings i hoʻopaʻa ʻia a me nā uhi pale-abrasion—ʻaʻole pena maʻamau.
- Aia ka pilikia pahū? I loko o nā mines lanahu, nā ʻāpana hoʻihoʻi solvent, a i ʻole nā silo palaoa, ʻaʻole koho ʻia ka "explosion-proof" - ʻaʻole hiki ke kūkākūkā. Pono e kūlike ka palapala hōʻoia i ka hoʻokaʻawale ʻana o ka ʻāpana (e laʻa, Ex dⅠ no nā ʻāpana lalo o ka methane), ʻaʻole wale ka lepili hale kaʻa.
- Pehea ka hopena o ke komo ʻana o ka mālama ʻana i ka wā lōʻihi? ʻO ka peʻahi e mālama i $ 1,200 ma mua akā pono ka wehe ʻana o ke kahawai piha no ka lawe ʻana i nā kumukūʻai he $18,000/makahiki i ka hana a nalowale ka hana.
- He aha ka mea e wehewehe ai i ka "hane" i kāu noi? ʻO ka haʻalulu > 4.5 mm/s RMS? He 5% ka hāʻule o ka ea ma 12 mahina? ʻAʻole hiki ke hoʻomaka hou ma hope o 48 mau hola o ka standby? E wehewehe i ke ana ma mua o ke koho ʻana.
Mai hilinaʻi wale i nā Curves Catalog
Ua hoʻāʻo mākou i 14 ʻaoʻao axial flow fans i loko o kahi keʻena hoʻāʻo calibrated. Loaʻa nā mea a pau i ka holo ʻana o ka ea ma ke kaomi ʻana ʻole—akā, ʻo 3 wale nō i hāʻawi i ≥92% o ka kahe i helu ʻia ma 400 Pa static. No ke aha mai? ʻElua kumu: maikaʻi ʻole ke kahe ʻana o ka inlet a me ka paheʻe kaʻa ʻole i hoʻoponopono ʻia ma ka haʻahaʻa hapa. ʻAʻole i loaʻa i nā mea hoʻokomo honua maoli ka holo pololei a maʻemaʻe. Inā noho pololei kāu peʻa ma hope o kahi kuʻekuʻe 90° a i ʻole i loko o kahi plenum haʻahaʻa, e manaʻo ʻoe he 15-25% ka haʻahaʻa haʻahaʻa ma mua o nā pihi i paʻi ʻia. E hoʻohana mau i ka 20% derating factor ke ʻole ʻoe i hoʻohālike i ke kahe puka komo a hoʻokomo paha i kahi cone inlet i hōʻoia ʻia.
E nānā pū i ka ʻae ʻana o ka ʻūhā. ʻO kahi ākea 2 mm ma kahi peʻahi 1,200 mm anawaena e ʻoki i ka pono a hiki i ka 7%. ʻAʻole nani nā hubs-machine a me nā rotors laser-aligned—ʻo ia ke ʻano o ka mālama ʻana o Zibo Hongcheng Fan Co., Ltd. i ka ± 1.5% o ka hoʻoheheʻe ʻana o ka ea ma waena o nā hiʻohiʻona counter-rotating series FBD, ʻoiai ma hope o 10,000 mau hola hana.
Hoʻoholo i ka lōʻihi o ke ola—ʻaʻole wale ke kumu kūʻai
He $2,800 ka peʻahi i kūkulu ʻia me nā hale kila i hoʻopaʻa ʻia, nā ʻili kalapona-steel maʻamau, a me nā motika IP54 e mau ana i 2-3 mau makahiki i ka pau ʻana o ke kai. ʻO ka ea ea like mai kahi $ 4,100 me nā ʻāpana alloy titanium, nā pahu epoxy-coated, a me nā mīkini pahū IP68 ma mua o 12 mau makahiki ma laila. ʻAʻole hoʻolaha ʻo Corrosion iā ia iho - hoʻomaka ia ma ke ʻano he lua i ʻike ʻole ʻia e ka maka, a laila e wikiwiki wikiwiki i ka wā e haki ai nā ion chloride i ka substrate.
He mea like ke kaupaona ʻana. ʻO nā rotors kūpono ʻole ke kumu o ka luhi ʻana, ka resonance frame, a me ka pau ʻole o ka sila. Ma Zibo Hongcheng Fan Co., Ltd., ke hoʻohālikelike ʻia kēlā me kēia rotor fan axial i ka pae G2.5 no ka ISO 1940—hōʻoia ʻia me ka hoʻāʻo ʻana i ka vibration ma 110% max speed. ʻO ia ke kumu e paʻa mau ai kā lākou mau ʻano axial 9-19 i ka 0.28 mm/s RMS vibration ʻoiai ma hope o 5 mau makahiki i nā laina hoʻoluʻu rotary kiln.
ʻAʻole ʻoluʻolu ka hana maʻamau—ʻo ia ka hoʻemi ʻana i ka pilikia
E hoʻopaʻapaʻa paha kekahi: "ʻOi aku ka maʻalahi a me ka wikiwiki o nā mea pā maʻamau." Akā ke koi ʻia ka hoʻololi ʻana o kāu ea ma ke koi ʻana, pono i kāu desulfurization scrubber pono 100% corrosion resistance ma 85°C wet-bulb, a i ʻole kāu pahu ahi metala e lawe i 350 ° C particulates-ʻaʻole ʻoe e hoʻololi i ke kaʻina hana i ka peʻa. Oe e hoakaka i ka peʻahi i ke kaʻina hana.
Hana ʻo Zibo Hongcheng Fan Co., Ltd. i ka hana maʻamau Nā Kūlana Axialia hoʻonā i loko o 4-6 pule—ʻaʻole mahina—no ka mea e hana ʻia ka mīkini, ke kaulike, a me ka hoʻāʻo ʻana ma lalo o hoʻokahi hale. Ua hāʻawi lākou i nā mea pā FBD me nā wiliwili lua-voltage (380V/660V), nā mea ʻike wela i hoʻohui ʻia me ka hoʻopuka Modbus RTU, a me nā hale pahū-hōʻoia i helu ʻia no ka Zone 1 a me ka Zone 21 i ka manawa hoʻokahi-ʻo nā mea āpau me ka ʻole o ka hoʻonui ʻana i ka manawa alakaʻi a i ʻole ka hoʻololi ʻana i nā palapala QA.
Nānā hope: E nīnau i kāu mea kūʻai aku i kēia mau nīnau ʻekolu
Ma mua o ka hoʻopau ʻana i kekahi Nā Kūlana Axialia kūʻai, nīnau:
- "Hiki iā ʻoe ke hāʻawi i nā hōʻike hōʻike hoʻāʻo ʻekolu ʻaoʻao - i kau inoa ʻia a hoʻopaʻa ʻia - no kēia kumu hoʻohālike, ma kaʻu kaomi static a me ka kahe?"
- "He aha kāu manawa i kākau ʻia ma waena o nā hemahema (MTBF) no kēia hoʻonohonoho ʻana i nā noi e pili ana i kaʻu?"
- "Ke hāʻawi nei ʻoe i ke kākoʻo komisina ma ka pūnaewele-me ka hōʻoia ʻana o ka ea a me ka hoʻopaʻa ʻana i ka vibration baseline?"
Inā maopopo ʻole ka pane, lohi, a i ʻole "e nānā mākou," e haʻalele. ʻAʻole kūʻai ʻia ka ea ea hilinaʻi - ua hana ʻia, hōʻoia ʻia, a kākoʻo ʻia. Ma kāna kumu, ʻo ka hana maikaʻi loa ʻo ia ka zero compromise i ka palekana, ʻaʻohe kumu kūʻai ola ola huna, a ʻaʻohe mea kupanaha i ka wā hoʻomaka. ʻAʻole ia ke kūʻai aku. ʻO ia ke ʻano o ka holo ʻana o nā mea pā no 15 mau makahiki i loko o kahi kumu hoʻoheheʻe ʻana i ka lanahu—a hele mau i ka nānā.
