Makina olowera mumigodi azitsulo si zida chabe - ndiye njira yoyamba yodzitchinjiriza pakufowoka, kuphulika, komanso kupsinjika kwa kutentha. M'zochitika zenizeni padziko lapansi, tawona kulephera kwa mpweya kumayambitsa anthu othawa mwadzidzidzi - osati chifukwa mafani adasokonekera, koma chifukwa sanatchulidwe mopanda tanthauzo chifukwa cha kuchuluka kwa methane, kutsitsa fumbi, kapena kusiyanasiyana kwadzidzidzi. Chochitika cha 2023 mu mgodi wa Shandong nonferrous chinatsimikizira izi: chifaniziro choyambirira cha axial chinakwaniritsa zolinga za airflow papepala koma sichinathe kupirira kupanikizika kwa static pamwamba pa 1,800 Pa pamene kukana kwa fyuluta kunawonjezeka ndi 40% pambuyo pa maola 72 akugwira ntchito mosalekeza. Ndi pamene kudalirika kumasiya kukhala ongoyerekeza.
Chifukwa chiyani "Kungoyenda Kwa Mpweya Wokwanira" Ndi Lingaliro Lowopsa
Migodi yachitsulo yapansi panthaka imafuna zambiri kuposa kutulutsa kwa volumetric. Amafunikira kuyankha kosunthika, kukhulupirika kwamapangidwe pansi pa kugwedezeka, ndi khalidwe lolephera kutetezedwa mumlengalenga wophulika. Mitundu ya FBD (dⅠ) yotsimikizira kuphulika-jakisoni yolimbana ndi axial flow ya m'deralo - yomwe imagwiritsidwa ntchito m'migodi yopitilira 37 ku China ndi Southeast Asia - idapangidwa makamaka kuti itseke kusiyana kumeneku. Kapangidwe kake kawiri-motor, kozungulira kozungulira kumapereka mphamvu ya 22-28% yokwera kwambiri kuposa ma axial unit agawo limodzi pamagetsi ofanana. Choyipa kwambiri, chiphaso chake cha Gulu Loyamba, Gawo 1 lotsimikizira kuphulika sichimangiriridwa - chimamangidwa mu geometry yanyumba yamagalimoto, mawonekedwe osindikizira a shaft, komanso njira yothamangitsira yoletsa moto.
Koma magwiridwe antchito sikuti amangokhudza mafotokozedwe. Ndi zomwe zimachitika pamene kutentha kwazungulira kugunda 52 ° C, chinyezi chikukwera pamwamba pa 95%, ndipo fumbi la silika limaposa 8 mg/m³. Standard fan fani alanda. Kutsika kwa Belt drive. Mapiritsi amoto amawonongeka. Ichi ndichifukwa chake kusankha makina opangira mpweya wazitsulo kuyenera kuyamba ndi mapu a chilengedwe-osati kusakatula pamakatalo. Tawona kuti makasitomala akuchepetsa nthawi yotumizira ndi 60% pomwe amagawana malipoti owunikira gasi wocheperako komanso ndandanda yatsiku ndi tsiku yonyamula miyala asanamalize kusankha mafani. Deta yeniyeni imaposa zongoganiza nthawi zonse.
Zitatu Zosakambirana mu Metal Mine Ventilation Design
- Umphumphu wotsimikizira kuphulika uyenera kupitirira kuposa injini. Mafani omwe adavotera madera a Zone 1 amalepherabe ngati mayendedwe olowera akulephera kupitiliza kapena ngati zotsekera zili ndi zomangira zosatetezedwa. Mndandanda wa FBD umaphatikiza zingwe zotsimikizika zoyambira molunjika ku flange yokwera-palibe kukonzanso m'munda komwe kumafunikira.
- Kugwira fumbi sikosankha - kumangowonjezera. Fani yotumiza 12,000 m³/h poyambira imatsika kufika pa 9,300 m³/h pakadutsa masiku 14 popanda kukonza ngati kusefera kolowera sikukwanira. Mafani a Titaniyamu-opangidwa kuti azikhala ndi dzimbiri, madera owonongeka kwambiri-amasunga> 94% ya mpweya wovotera pakadutsa masiku 30 popanda kuyeretsa.
- Kuwongolera kuyankha kumakhudza mobisa. Ma frequency a frequency drives (VFDs) amayenera kuchita mkati mwa masekondi 1.2 ku CO sensa zoyambitsa. Mayunitsi okhala ndi malupu owongolera a analogi okha amawonjezera masekondi 4-7 a latency-nthawi yokwanira kuti mayendedwe a methane awoloke 5% LEL poyimitsa malo otsekeka.
Pamene Off-the-Shelf Siikutetezedwa Mokwanira
Ena angatsutse kuti mafani amakampani omwe amagwira ntchito bwino amagwira ntchito bwino ndi zowonjezera zowonjezera chitetezo. Komabe, kuwonjezera zotchingira zakunja zoteteza kuphulika kwa axial fan-cholinga kumapangitsa mabotolo amafuta, kumachepetsa mwayi wautumiki, ndikuchotsa ziphaso zoyambira zida. Choyipa chachikulu, imabweretsa zolephera zatsopano: kutayika kwa gasket, kuwonongeka kwa chisindikizo, komanso kutopa kwa waya wonjenjemera. Kupanga mwamakonda sikutanthauza kukongola-ndikuchotsa malo omwe ali pachiwopsezo.
Zibo Hongcheng Fan Co., Ltd. imamanga mfundoyi mumayendedwe ake. Pamene mgodi wamkuwa ku Yunnan unkafuna fani yokhoza 3,200 Pa static pressure pa 8,500 m³/h ikugwira ntchito mosalekeza pa kutentha kwa 75 ° C, akatswiri sanasinthe chitsanzo chomwe chinalipo. Adayendetsanso mbiri ya blade twist mu ANSYS CFX, yosankha Inconel 625 ya ma rotor hubs, ndikutsimikizira kulolerana kwa kutentha kwa maola 120 pamayeso oyaka. Chotsatira? Chigawo chovomerezeka ku GB 3836.1–2021 ndi ISO 8573–1 Kalasi 2 cha kuipitsidwa kwa tinthu tating'ono ting'ono-choperekedwa m'milungu 11, osati miyezi isanu ndi umodzi.
Zomwe Zimabwera Pambuyo pa Invoice Ndizofunika Kwambiri
Wothandizira migodi wachitsulo samapeza mtengo wake pakuyika-imadziwonetsera yokha pakusintha kwachitatu kwa sabata 17. Ndipamene ma vibration harmonics amavumbulutsa kusalinganika, pamene kunyamula kutentha kumavumbula kusagwirizana kwa mafuta, komanso pamene malingaliro owongolera amavumbulutsa nsikidzi za firmware. Zibo Hongcheng Fan Co., Ltd. imaphatikizapo kukonzekera kwakutali mu FBD ndi titaniyamu-mndandanda wa mayunitsi: Thandizo la Modbus TCP, masensa am'madzi otentha / kupanikizika / kugwedezeka, ndi zowongolera zosinthika za firmware. Akatswiri am'munda samadikirira kuwonongeka - amawona zopotoka pakuwonjezeka kwa 3% matalikidwe, osati 30%.
Ntchito sikugwira ntchito. Ndizolosera. Gulu lawo lauinjiniya limawunikanso njira zoyendetsera mpweya wa mgodi asanaperekedwe - osati kuti agulitse, koma kuti awonetse kutalika kwa ma ducts, chipwirikiti chopangidwa ndi chigongono, kapena kukonza kachulukidwe kotengera kukwera komwe kumasintha mphamvu zamahatchi mpaka 11%. Chisamaliro chimenecho chimalepheretsa kubwezeredwa kwamitengo yotsika mtengo ndikupangitsa kuti ndege zizigwirizana ndi miyezo yachitetezo yaku China ya AQ 2013-2018.
Mpweya wabwino wovuta kwambiri pachitetezo ulibe malo onyengerera. Wothandizira mpweya uliwonse wachitsulo ayenera kuyankha mafunso atatu asanatumizidwe: Kodi imapulumuka chilengedwe? Kodi imayankha kuzizindikiro zowopsa mwachangu kuposa nthawi yomwe anthu amachita? Kodi chithandizo chake chachilengedwe chimayembekezera njira zolephera - osati kungolemba? Zibo Hongcheng Fan Co., Ltd. amayankha kuti inde-osati monga zonena zamalonda, koma monga malipoti oyesa, zipika zam'munda, ndi zolemba zowerengera za gulu lachitatu. Chifukwa chapansi panthaka, mayendedwe a mpweya samayezedwa mu ma kiyubiki mita pamphindi. Zimayesedwa m'miyoyo yokhazikika, kusintha komwe kumatsirizidwa, ndi zochitika zadzidzidzi zimapewedwa.
