ʻAʻole pili ka hoʻoheheʻe ʻana o ka tunnel i ka hoʻoneʻe ʻana i ka ea-e pili ana i ka mālama ʻana i nā ola, ka pale ʻana i ka piʻi ʻana o ke ahi, a me ka mālama ʻana i ka makaʻala o ka mea hoʻokele i nā wahi paʻa a me ka pilikia. Ke piha ka uahi i kahi tunnel alanui 3-kilomita i ka wā o kahi hanana, helu ʻia kēlā me kēia kekona. ʻO ia ke kumu ʻaʻole hoʻoholo nā ʻenekinia i nā mea pā maʻamau. Hōʻike lākou SDS Series Jet Fan nā ʻāpana—ka hana pololei, hoʻopaʻa ʻia, a hoʻāʻo ʻia ma lalo o ke koʻikoʻi wela a me ka aerodynamic.
No ke aha SDS Series Jet Fans e hāʻawi i ka palekana Tunnel maoli—ʻaʻole wale i nā helu ea
Ua ʻike mākou i nā papahana he nui i hāʻule - ʻaʻole mai ka hoʻolālā maikaʻi ʻole, akā mai nā koho pā like ʻole. He liʻiliʻi ke ʻano o ka mea peʻahi i helu ʻia ma 30,000 m³/h inā hāʻule ka helu hoʻokuʻu ʻana i 18% ma 55°C a i ʻole ke kulike ʻana o kona ʻāʻī me nā alapine haʻalulu maʻamau. ʻO ka SDS Series Jet Fan pale i kēia mau lua ma ka hoʻolālā.
Hāʻawi kēlā me kēia ʻāpana i ka hoʻoikaika mau ʻana ma waena o ka pae hana holoʻokoʻa: 1,800–4,200 N i kēlā me kēia peʻahi, ma muli o ke kumu hoʻohālike a me ka hoʻonohonoho kaʻa. ʻAʻole like me nā ʻāpana axial kahiko i nalowale ka hana ma luna o 45°C, hoʻohana ka poʻe SDS i ka insulation Class H a me ka thermally stable composite blades — hoʻāʻo mau ʻia ma 70°C inlet air no 72 mau hola me ka ʻole o ka neʻe ʻana o ka hana. Ua hōʻoia mākou i kēia i ka wā o ka hoʻāʻo ʻana i ka makahiki 2023 ma kahi tunnel mauna kokoke i Lanzhou: ʻekolu mau ʻāpana SDS-1250 i mālama ʻia he 96.3% o ka pahu helu ma hope o 48 mau hola o ka hana mau ʻana ma 62°C ambient a me 85% humidity pili.
He mea nui ka kau ʻana e like me nā kikoʻī kaʻa. Hoʻopili pololei nā mea pā SDS i ka ISO 10816-compliant vibration isolation i loko o ke kākoʻo paʻa—ʻaʻohe pā-welded brackets, ʻaʻohe degradation pad rubber. Hoʻokiʻoki kēia i ka manawa hoʻokomo e 40% a hoʻopau i ke kumu maʻamau o ka hāʻule ʻole o ka lawe ʻana i ka wā o nā noi tunnel: misalignment-induced dynamic loading.
He aha ka mea e hana ai nā poʻe SDS ma kahi e kū ai nā poʻe ʻē aʻe—Ma ke ʻano maoli a me ke ʻano loea
Hiki i kekahi ke hoʻopaʻapaʻa ua lawa ka peʻahi axial kiʻekiʻe no ka hoʻohana ʻana i ka tunnel. Eia nō naʻe, ʻaʻole paʻa mau ka ea o ka tunnel honua maoli - he pulsed, asymmetric, a haumia. ʻO nā ʻāpana lole Diesel. Hoʻokaʻawale ʻia ka hoʻokaʻawale ʻana o ke kahe. Hoʻokumu nā ala kaʻa ulia pōpilikia i nā spike backpressure transient.
Mālama ka SDS moʻo i nā mea ʻekolu no ka mea ua kūkulu ʻia a puni ʻekolu mau hiʻohiʻona hiki ʻole ke kūʻai aku:
- ʻO nā impeller ʻelua e hoʻohuli kūʻē-ʻaʻole wale no ke kiʻekiʻe kiʻekiʻe, akā no ka hoʻihoʻi hou ʻana i ka ikaika ma hope o nā ʻāpana recirculation;
- Hoʻohui ʻia CFD-hōʻoia shroud geometry—e hoemi ana i na poho vortex ma ka 22% ku e i na manao hoohihi hookahi (no ka hooiaio ana o ka tunnel makani o ka aoao ekolu);
- Nā koho kaʻa pahū-pahū modular—hōʻoia ʻia i ka GB 3836.1–2021 a me IEC 60079–0:2017, me ke koho ʻana i ka ATEX Zone 1/21 e hōʻailona ana no nā tunnels lawe kemika.
Ua hoʻololi mākou i ʻeono mau mea pā 110 kW kahiko i loko o kahi kaila conveyor lanahu me ʻehā mau ʻāpana SDS-1600. Ua hāʻule ka hoʻohana ʻana i ka ikehu ma 31%, ua pāpālua ʻia nā wā mālama, a—me ka koʻikoʻi—hoʻomaka hou ka ʻōnaehana i loko o 2.3 kekona ma hope o ka pau ʻana o ka mana. He mea nui kēlā wikiwiki i ka wā e hoʻomaka ai ka ea ma mua o ka haki ʻana o nā pae CO i 30 ppm.
ʻAʻole ʻoluʻolu ka hana maʻamau - ʻo ia ke koi kumu
ʻAʻohe ʻelua tunnel i kaʻana like. Pono kekahi e pale i ka corrosion i nā aerosol paʻakai de-icing. Pono kekahi i nā ʻāpana titanium no ka hoʻopau geothermal waiwai nui i ka sulfur. ʻO ke kolu e koi i nā diagnostics mamao ma o Modbus TCP me ka mahana o ka moku, ka haʻalulu, a me ka nānā ʻana.
Hana ʻo Zibo Hongcheng Fan Co., Ltd. i ka hana maʻamau ma ke ʻano he kaʻina kumu—ʻaʻole lawelawe hoʻohui. Hāʻawi kā lākou SDS series:
- ʻEkolu mau koho voltage maʻamau (380 V / 660 V / 1140 V), me ka ± 10% ka hoʻomanawanui a me ke kānana harmonic;
- ʻO nā pahu junction i koho ʻia IP68 me nā komo kelepona i hoʻopaʻa ʻia i ka silicone;
- ʻO nā mea lāʻau: aluminika alumini (maʻamau), kuhili ʻole 316L, a i ʻole ka papa 2 titanium no ka H₂S a i ʻole ka chloride hoʻolaha;
- Hoʻohui piha me nā kahua BMS—me ke kākoʻo ʻōiwi no KNX, BACnet MS/TP, a me MQTT protocols.
Pono kekahi mea kūʻai ma Jiangsu i nā mea pā SDS no kahi alahao kaʻa i lalo o ka moana kahi i ʻoi aku ai ke komo ʻana o ka noe paʻakai ma mua o 500 mg/m³/lā. Ua hāʻule ka uhi epoxy maʻamau i loko o 14 mau mahina. ʻO ka hoʻonā? ʻO nā pahi Titanium + nā hale kaʻa i uhi ʻia i ka seramika + nā sila ea hoʻomaʻemaʻe kaomi ʻia. Hāʻawi ʻia i loko o 11 mau pule—me ka hoʻopaneʻe ʻole ʻana i ka hana ʻana o ka tunnel.
ʻO ke koho ʻana i ka pā SDS kūpono ʻo ia ka nīnau mua ʻana i nā nīnau kūpono
Ma mua o ka wehewehe ʻana i kekahi SDS Series Jet Fan, e nīnau i kāu mea hoʻolako i kēia mau nīnau ʻelima—a koi i nā pane i kākau ʻia:
- He aha ka nui o ka pohō o ka pahu i 65°C a me 90% RH ma luna o 1,000 hola?
- Hiki iā ʻoe ke hāʻawi i nā hōʻike hoʻāʻo ʻekolu e hōʻoia ana i ka hoʻokuʻu ʻana o ka walaʻau ≤78 dB(A) ma 3 mika, nā kūlana manuahi?
- Pehea ʻoe e hōʻoia ai i ka pono o ke kūkulu ʻana no ka Seismic Zone 8 (0.3g horizontal acceleration)?
- He aha ka manawa ma waena o nā hemahema (MTBF) no ka kaʻa ma lalo o ka hana mau 24/7?
- Ke hāʻawi nei ʻoe i ke kākoʻo komisina ma ka pūnaewele-me ka palapala ʻāina ea a me ka hōʻoia calibration thrust?
Hoʻopuka ʻo Zibo Hongcheng Fan Co., Ltd. i nā ʻikepili hoʻāʻo a pau. ʻAʻole i loko o kā lākou palapala moʻo SDS wale nō nā pihi hoʻokō static - akā nā palapala pane hoʻoikaika e hōʻike ana i ka manawa hoʻihoʻi hou ma hope o 0-100% hoʻololi i ka pae hoʻouka, a me nā hōʻike kiʻi wela e hōʻoia ana i nā wahi wela i ka wā o ka hoʻāʻo ʻana.
Ke ulu nei ka palekana tunnel. No laila pono ka ʻenehana ventila. ʻO ka SDS Series Jet Fan ʻaʻole ia he laina huahana ʻē aʻe - ʻo ia ka hopena o ʻelua mau makahiki o ka manaʻo o ke kahua, ka hoʻohālikelike ʻana i ka wela, a me ka hoʻopaʻi ʻana i ka hana ʻole. Ke hilinaʻi nā ola i ka ea, ʻaʻole ana ʻia ka hilinaʻi ma nā kikoʻī. Ua hōʻoia ʻia i loko o nā tunnel i piha i ka uahi, i ka hola 3 a.m., i ka wā ʻino loa o ka makahiki.
