Mine ventilation fan kusankha si mndandanda wa zogula - ndi chisankho chofunikira kwambiri chaumisiri. Kusankha kumodzi kolakwika kungatanthauze kuchuluka kwa methane, kupsinjika kwa kutentha, kuwunjikana kwafumbi kopumira, kapena kuyatsa kowopsa m'malo ophulika. Taziwonapo: mgodi ku Inner Mongolia udasintha mawonekedwe ake okalamba a axial ndi gawo losavomerezeka kuti achepetse ndalama - m'miyezi itatu, milingo ya CO idakwera panthawi yakusintha. Malo ena ku Shanxi anaika ndi undersized centrifugal chilimbikitso popanda kuwerengera kutayika ngalande khola mikangano; mpweya watsika ndi 38% pamaso. Uku sikunali kulephera kwa zida. Zinali zosagwirizana mwatsatanetsatane.
Fananizani Mtundu Wamafani ndi Ntchito Yotulutsa Mpweya—Osati Voliyumu Ya Mpweya Wokha
Mafani a Axial flow amayang'anira mpweya wabwino wa m'deralo - makamaka pafupi ndi nkhope zogwirira ntchito - chifukwa amapereka mpweya wokwera kwambiri komanso kuthamanga kotsika. Koma "kuthamanga kwa mpweya" sikutanthauza kanthu popanda nkhani. The FBD mndandanda (dⅠ) wotsimikizira kuphulika kwa axial flow fan, mwachitsanzo, imakwaniritsa 20–45 m³/s pa 3,000–6,500 Pa static pressure, yokhala ndi zopangitsa zapawiri zozungulira mosiyanasiyana. Kapangidwe kameneka kamathetsa chipwirikiti chozungulira, kumawonjezera mphamvu mpaka 12%, ndikuchotsa kufunika kowongola mavane m'magawo olimba. Mosiyana ndi izi, fani ya axial yamtundu umodzi ya kukula kofanana imatha kukhazikika pamene kuthamanga kwa static kupitirira 2,200 Pa-yofala mumayendedwe aatali, opindika, kapena otsekedwa pang'ono.
Mafani a centrifugal amalowa komwe kupanikizika kumafunika kwambiri kuposa kuchuluka kwa mphamvu: ma shafts olowera, malo olimbikitsira, kapena ma ducts a desulfurization. The 9-19 high-pressure centrifugal blower imagwira 1,200–12,000 m³/h mpaka 15,000 Pa—yoyenera kuthana ndi kukana kuchokera ku zokolopa, zosefera, kapena kukweza molunjika. Choyambitsa chake chokhotakhota chakumbuyo chimayenda mozizirira, chimalimbana ndi kuchuluka kwa fumbi, ndipo chimasunga magwiridwe antchito mokhazikika pamikhalidwe yosiyanasiyana. Zowombera mizu? Pokhapokha potengera kusamutsa kwa gasi kwanthawi zonse, kopanda mpweya—monga kubwereketsa gasi wa malasha—osati mpweya wamba.
Umboni Wophulika Siwosasankha-Sizokambirana mu Migodi ya Gassy
Ogwira ntchito ena amawona ziphaso zodzitchinjiriza ngati vuto la zolemba. Si. Ndi njira yosungira thupi. A certified mgodi wa malasha wotsimikizira kuphulika kwa axial flow fan Iyenera kukwaniritsa miyezo ya GB 3836.1–2021: nyumba zoyesedwa kuti zipirire kuphulika kwamkati popanda kufalikira kwa lawi lamoto, kutentha kwa pamwamba kumasungidwa pansi pa T4 (135 ° C), ndi malo ololedwa pakati pa magawo ozungulira ndi osasunthika omwe amatha kulekerera ma micrometer. Tidayeza kutentha kwapamtunda pamayunitsi osatsimikizika omwe akugunda 172 ° C mkati mwa maola 4 akugwira ntchito mosalekeza - kupitilira malire otetezeka a zosakaniza za mpweya wa methane.
Kutsimikizira zenizeni padziko lapansi ndikofunikira. Chigawo chilichonse cha FBD(dⅠ) chimayesedwa ndi kutenthedwa kwa maola 72 pansi pa katundu wolemera wa methane, ndikutsatiridwa ndi kuyerekezera kwamafuta ndi kutsimikizika kwapang'onopang'ono. Palibe satifiketi yomwe imaperekedwa mpaka fani itadutsa macheke amakina komanso kukhazikika kwa kutentha.
Iwalani "Kukula Kumodzi Kukwanira Zonse" -Kusintha Mwamakonda Kumathetsa Mavuto Amtundu Weniweni
Zolemba zokhazikika zimalephera mobisa. Duct diameter imasintha pakati pa kuthamanga? Onjezerani ma cones a tapered inlet. Mpweya wodzaza ndi H₂S wodzaza ndi malasha akuya? Tchulani zoyika pa titaniyamu ndi zokutira za epoxy zosagwira asidi - osati chitsulo chosapanga dzimbiri. Kutentha kwakukulu kozungulira 50 ° C? Sinthani kutenthetsa kwamagalimoto kupita ku Gulu H ndikuwonjezera zipsepse zoziziritsa zakunja. Nthawi ina tidapanganso nyumba zonyamulira za projekiti ya hydropower ya Yunnan pambuyo pakuwunika kwa vibration kuwululira kumveka kwa 2,350 RPM-yomwe idachitika chifukwa cholumikizana ndi ma conveyor drive moyandikana. Kukonza? Kusinthidwa pafupipafupi kwachilengedwe ndi 18% kudzera pakusintha makulidwe a khoma ndi zoyika zonyowa. Zaperekedwa m'masiku 11.
Zibo Hongcheng Fan Co., Ltd. Mainjiniya samagawira zojambula kuti apange - amalumikizana ndi akatswiri opanga makina, akatswiri ochita bwino, ndi ogwira ntchito ku labotale. Zopempha mwamakonda—kaya kusindikiza kwa IP68, kutsatira ATEX Zone 1, kapena kuphatikiza ndi SCADA kudzera pa Modbus RTU—zimayambitsa kuunikanso kosiyanasiyana musanatchule. Nthawi yotsogolera imakhala yodziwikiratu chifukwa kusintha mwamakonda kumachitika mkati mwa malo omwewo a 9,000 m² momwe zopangira zimalowa ndikutumiza mayunitsi oyesedwa.
Yang'anani Kuseri kwa Nameplate-Yang'anani Njira Zomwe Zili M'mbuyo Mwazogulitsazo
Wokonda adavotera 5,000 Pa samatsimikizira 5,000 Pa patsamba lanu. Magwiridwe ake amawonongeka ndi kukokoloka kwa tsamba, kuvala, kusinthasintha kwamagetsi, kapena kusokoneza kwa malo. Ichi ndichifukwa chake Zibo Hongcheng amayesa gawo lililonse pansi pa zochitika zenizeni zapadziko lapansi: kuyenda kwa mpweya kumatsimikiziridwa ndi ma pitot array, kukakamizidwa kovomerezeka ndi manometers adijito omwe amatsatiridwa ndi NIM, kuchita bwino kuwerengeredwa pogwiritsa ntchito njira zotsata ISO 5801. Lipoti lililonse limaphatikizapo kukokedwa kwenikweni kwa mphamvu - osati kuchuluka kwa magalimoto - komanso kuchuluka kwa phokoso loyezedwa pa mita imodzi pa ISO 3744.
Chilango chimenechi chimakhala chofunika kwambiri kumene moyo umadalira kugwirizana. Pamene mgodi wazitsulo ku Gansu unkafuna mafani olowa m'malo mwa makina ake otulutsa mpweya, sitinangofanana ndi mpweya. Tinajambula mapu a kutentha pamtunda, kufananiza kuchuluka kwa ma abrasion, ndikusankha chofanizira chapawiri-inlet centrifugal chokhala ndi nsonga zokutira za ceramic ndi ma bere oziziritsidwa ndi madzi. Tsopano ikuyendetsa maola 22,000 popanda kukonza-kuposa zomwe OEM amayembekezera ndi 40%.
Kusankha choyenera mine mpweya fan imayamba ndi kufunsa mafunso ovuta-osati okhudza mtengo kapena kubweretsa, koma za kulephera, kunyanyira kwa chilengedwe, ndi kuzama kotsimikizira. Zimatanthawuza kusankha anzanu omwe amayesa pansi pa katundu, mainjiniya kuti awonongeke, komanso kuchitira satifiketi ngati fiziki - osati zolemba. Chifukwa m'ntchito zapansi panthaka, kuyenda kwa mpweya sikumveka. Ndi oxygen. Ndi dilution. Ndi malire pakati pa kusintha kwachizolowezi ndi lipoti la zochitika.Mine Ventilation Fan
