Mpweya wabwino wa ngalande sikutanthauza kusuntha mpweya-komanso kuchirikiza moyo, kuteteza zomangamanga, ndi kupewa kulephera koopsa. Mumsewu wa njanji wamakilomita 3.2 womwe tidawunika chaka chatha, kusayenda bwino kwa mpweya kudapangitsa CO kuchulukirachulukira pamaulendo apamtunda, zomwe zidayambitsa kuyimitsidwa kwadzidzidzi katatu m'mwezi umodzi. Chochitika chimenecho sichinali chifukwa cha kukula kwa mafani. Zinali chifukwa cha *kusagwirizana bwino*: gawo loyikapo lomwe lidaperekedwa lidavotera CFM pokhapokha pazingwe zokhazikika-zopanda ntchito pama ductwork enieni okhala ndi ma bend, ma grill, ndi zozimitsa moto. Apa ndi pamene kuyatsa Kuthamanga kwambiri kwa tunnel fan machitidwe amatsimikizira kukhala ofunikira -osati monga zongoyerekeza pa database, koma ngati mayankho ovomerezeka omwe amasunga> 82% kuchita bwino pa 800-2,200 Pa static pressure range.
Chifukwa chiyani "Kuchita Bwino Kwambiri" Sikungokhala Chilankhulo Chotsatsa
Mafani ambiri amsewu amataya 35-50% yamphamvu yawo ya nameplate akamagwira ntchito mosagwirizana ndi zenizeni. Chifukwa chiyani? Ma aerodynamics olakwika, kutayika kwa ma fan fan, komanso geometry ya casing yosasinthika. Nkhani zoyatsira zimafotokoza mfundo iliyonse mwadala. Cholowa chake chakumbuyo chokhotakhota chimagwiritsa ntchito mbiri ya NACA 63-018 ya airfoil yovomerezeka poyesa njira yamphepo-osati zoyerekeza za CFD zokha. Tayesa nsonga yake yogwira ntchito bwino pa 1,450 Pa static pressure, osati 100 Pa. Izi zikutanthauza kuti zimapereka mpweya wogwiritsidwa ntchito kumene kuli kofunikira: kumapeto kwa njira ya 1,500-mita yothamanga ndi zigongono zisanu ndi chimodzi za 90 ° ndi banki ya fyuluta ya particulate. Kuphatikizika kwa magalimoto kumatsatira miyezo ya IEC 60034-30-2 IE4, yokhala ndi kasinthidwe kachindunji komwe kumachotsa kutsetsereka kwa lamba ndi kusuntha kwamayendedwe. M'mawu aposachedwa a migodi ya malasha, zomwe zidatembenuzidwa kukhala 28% kutsika kWh/m³ kuyerekeza ndi mtundu wakale wa axial - zatsimikiziridwa pa miyezi 14 yodula mosalekeza.
Kudalirika Kwapadziko Lonse Kumafuna Zambiri Kuposa Ma IP
Chitsimikizo chosaphulika (dⅠ) kapena chitetezo cha IP65 sichitanthauza pang'ono ngati kuwongolera kwamafuta kulephera pakatha miyezi 18 yogwira ntchito 24/7. Tawona mafani akuyesa mayeso afakitale koma akuwotcha muutumiki chifukwa zipsepse zoziziritsa zidali zocheperako pakukweza fumbi. Choyatsira chotenthetsera chapamwamba kwambiri chimagwiritsa ntchito njira ziwiri zotenthetsera: nyumba zakunja zimachotsa kutentha kwa rotor, pomwe zisindikizo zamkati za labyrinth zimalepheretsa kubwereza kwa gasi wotentha kulowa mumotoka. Dongosolo lake lonyamulira limaphatikiza mipira ya SKF Explorer yakuya-groove yokhala ndi ma shafts okutidwa ndi ceramic-yoyesedwa mpaka maola 40,000 MTBF pa 65 ° C ambient. Chofunika kwambiri, gawo lililonse limayesedwa maola 72 pa liwiro la 110% ndi 120% static pressure isanatumizidwe. Palibe sampuli zamagulu. Palibe "ntchito yodziwika bwino." Wokonda aliyense amapeza nambala yake pa benchi yoyesera.
Kusintha Mwamakonda Omwe Simasokoneza Kutumiza kapena Kutsata
"Mwambo" nthawi zambiri amatanthauza nthawi zotsogola za masabata 16 ndi ziphaso zochotsedwa. Osati pano. Zibo Hongcheng Fan Co., Ltd. imasunga ma modular subassemblies - ma impeller hubs, mbale zoyikira ma mota, ma cones olowera - omwe amalumikizana popanda kukonzanso. Mukufuna chiphaso cha ATEX Zone 1 chokhala ndi masamba a titaniyamu pamachubu amafuta olemera a H₂S? Zachitika m'masabata 6. Amafuna ntchito yapawiri-voltage (380V/660V) yokhala ndi njira yophatikizira ya VSD yosunga zosunga zobwezeretsera dizilo mwadzidzidzi? Njira yokhazikika. Chomwe chimawalekanitsa ndi momwe amachitira ndi malonda: kukana dzimbiri sikutanthauza kutaya mphamvu zokhazikika. Zovala zawo zotsutsana ndi corrosion epoxy (ISO 12944 C5-M) zimawonjezera <0.8 mm makulidwe - kuyesedwa ndi kutsimikiziridwa - osati kungopoperapo. Ndipo inde, apereka malipoti oyeserera opopera mchere a chipani chachitatu osonyeza kuti palibe matuza pakatha maola 2,000, osati "kukwaniritsa zonena".
Kusankha Bwino Kumatanthauza Kufunsa Mafunso Oyenera Choyamba
Musanatchule chilichonse kuyatsa Kuthamanga kwambiri kwa tunnel fan, yankhani zisanu zomwe sizingakambirane:
- Kodi static pressure curve yanu ndi yotani? Osati "mpaka 2,000 Pa" -koma kuthamanga kumatsika pa 100 m pa liwiro la mapangidwe, kuphatikizapo zopangira zonse.
- Kodi kutentha kwanu koyipa kwambiri ndi kotani komanso fumbi? Kuyeza kusefera kwa ISO 16890 ePM1 kumafunika kwambiri kuposa zolemba "zochita bwino kwambiri".
- Kodi mukufunikira kubweza kolephera? Mitundu yoyatsira imathandizira kuyambika koyambiranso mkati mwa masekondi 1.8 - yofunika kwambiri pamapulogalamu ochotsa utsi.
- Kodi kudzipatula kwa vibration kumangidwira kapena ndikowonjezera? Mapiritsi awo a elastomeric okhala m'munsi amachepetsa kufalikira kwa ≤2.5 mm / s RMS pakudzaza kwathunthu-palibe kuwotcherera kumunda komwe kumafunikira.
- Kodi ndi nthawi yotani yomwe yalembedwa kuti mutengere m'malo? Osati "zaka 2 zilizonse" -koma zidziwitso za maola ogwiritsira ntchito zomwe zimagwirizanitsidwa ndi kusanthula kuwonongeka kwa mafuta.
Izi siziri mndandanda wazinthu. Ndi njira zolephera zomwe zikuyembekezera kuchitika. Nkhani zoyatsira zilipo chifukwa mainjiniya amafunsabe kuti: "Bwanji ngati faniyo ikugwira bwino ntchito - koma makinawo akutsamwitsidwa?" Mtengo wake suli mu manambala apamwamba. Zili m'ntchito yokhazikika pomwe ena amatsitsa. Kumene kudalirika sikuganiziridwa - kumatsimikiziridwa, kusungidwa, ndi kutsimikiziridwa. Kwa ngalande zomwe zimawerengera masekondi ndi malire ake, kuyenera kupangidwa mwaluso - osayerekezedwa.
