Kuyenda kwa mpweya kukalephera mumsewu, chitetezo chimalephera poyamba. Taziwonapo zikuchitika: kutentha kwa kutentha pafupi ndi malo okumba, CO kuwonjezereka muzitsulo zokonza njanji, mpweya woyimitsidwa panthawi yobowola mwadzidzidzi. Chifukwa chake mainjiniya amafotokozera SDF mndandanda wa tunnel fan-osati ngati chowuzira cha generic, koma ngati kuyankha kotsimikizika kumunda kuzinthu zitatu zosakambitsirana: kukankhira mosalekeza pakutaya kutsika kwamphamvu, kugwira ntchito mokhazikika pansi pamikhalidwe yodzaza fumbi kapena chinyezi, ndi kulekerera zero kuthawa kwamafuta. Zibo Hongcheng Fan Co., Ltd. adapanga zotsatizanazi kuyambira pansi mpaka pano kuti zikhale zenizeni - osati zolemba za labu.
Chifukwa chiyani Mafani a SDF Series Tunnel Amapereka Kumene Ena Amayimilira
Mpweya wa ngalande sikutanthauza kusuntha mpweya. Zimakhudza kusuntha * mpweya wabwino *, pa * liwiro loyenera *, kudzera * kusintha kukana *, kwa *miyezi yopanda ntchito *. Mndandanda wa SDF umakumana ndi mayesowa ndi osiyanitsa atatu.
Choyamba, choyikapo chake chopondera chozungulira chapawiri chimapereka mphamvu ya 15-22% yapamwamba kwambiri kuposa mafani a axial agawo limodzi pamagetsi ofanana - otsimikiziridwa kudutsa 12 pamalo omwe amatumizidwa ku migodi ya malasha ya Shandong. Chachiwiri, nyumba yamagalimoto imaphatikiza zisindikizo zafumbi za IP55 * ndi * Kutsekereza kwa Gulu H, kupangitsa kuti ntchito isasokonezeke pa 45 ° C ambient + 85% RH -mikhalidwe yomwe mafani okhazikika amateteza chitetezo pambuyo pa maola 72. Chachitatu, gawo lililonse limatumiza zokhala ndi zowongolera zolowera, zomwe zimalola kusintha kwa mpweya kuchokera pa 60% mpaka 100% mphamvu popanda kutayika kwamphamvu kapena chiwopsezo cha resonance.
Sitidalira ma curve a catalog. Pakutumidwa mumsewu waukulu wa 3.2-km ku Gansu, tidayesa kukana kwenikweni kwa 1,280 Pa-osati 950 Pa yomwe imaganiziridwa. Mtundu wa SDF-16 unasunga 98.3% ya mpweya wovotera panthawiyo. Mafani opikisana adatsika mpaka 71%. Mphepete mwa nyanjayo idapangitsa kuti dizilo likhale pansi pa 0.05 mg/m³ panthawi yonse yomanga.
Zomwe Ogwiritsa Ntchito Kwenikweni Amakonza—ndi Chifukwa Chiyani
Magulu ogula zinthu amatifunsa mafunso atatu tisanayitanitsa:
- "Kodi ingathe kuthana ndi kusintha kwa magetsi athu?" Inde-mitundu yodziwika bwino imavomereza kusiyanasiyana kwa ± 10% (380V ± 38V) popanda kutsitsa. Ma module oyambira pang'onopang'ono amadula ma inrush apano ndi 65%, omwe ndi ofunika kwambiri pazigawo zakutali.
- "Kodi tikufunika zoteteza kuphulika?" Pokhapokha ngati methane> 0.5% LEL ikuyembekezeka. Pamachubu ambiri amisewu/njanji, mayunitsi wamba a SDF amakumana ndi GB/T 13306–2011 kumadera omwe si oopsa. Kugwiritsa ntchito mgodi wa malasha kumafuna mitundu yosiyanasiyana ya FBD-mzere wosiyanasiyana wazinthu, njira zosiyanasiyana zotsimikizira.
- "Kodi titha kupeza zotsalira mwachangu bwanji?" Zida zonyamula, zolemetsa zonyamula, ndi ma PCB owongolera amatumiza mkati mwa maola 48 kuchokera ku Zibo. Palibe kuchedwa kosungirako katundu kunja.
Kupanga mwamakonda sikungogulitsa - ndi mchitidwe wamba. Chaka chatha, pulojekiti ya metro ku Chengdu inkafunika mayunitsi a SDF-20 okhala ndi zitsulo zosapanga dzimbiri (316L), ma shaft otalikirapo olumikiza makhoma awiri, ndi mayankho a 4-20 mA pa kutentha kwa mpweya. Zaperekedwa m'masiku 18. Palibe kukonzanso. Chilango cha uinjiniya basi.
Kuyika Reality Kumayang'ana Mapepala Ambiri Osanyalanyaza
Kukwera kumafunika kwambiri kuposa mphamvu ya akavalo. Tawona zolephera ziwiri zomwe zimachitika mobwerezabwereza:
Choyamba, kugwedezeka kwa makoma m'makoma a konkire pamene mbale zoyambira zilibe zodzipatula za 12-mm neoprene. Zotsatira: ming'alu yaying'ono m'mizere yowombera pambuyo pa miyezi 6. Magawo a SDF amaphatikizanso ma pad m'mawu oyika -osati ngati mawu am'munsi, koma monga Gawo 3 pakutsatizana kwa torque.
Chachiwiri, kutembenuzira kayendedwe ka mpweya chifukwa cha geometry yolakwika ya duct transition. Mndandanda wa SDF umagwiritsa ntchito chidindo chozungulira kumanzere/kumanja chodinda molunjika pabokosi, osati zilembo zokha. Timaperekanso ma tempuleti olumikizirana ndi laser kotero kuti oyika amatsimikizira malo olowera/motuluka asanatseke.
Chigawo chilichonse chimakhala ndi mphamvu zochulukirapo pa 110% RPM mnyumba. Osati kokha "kulinganiza ku G2.5" -timalemba vekitala yotsalira (grams·mm) pa rotor iliyonse. Deta imeneyo imayenda ndi fan. Ngati kugwedezeka kukukwera pambuyo pake, akatswiri amafananiza motsutsana ndi maziko - osati kungoyerekeza.
Mfundo Yofunika Kwambiri: Kudalirika Mungathe Kuyeza
Chotsitsa chamsewu cha SDF sichimatanthauzidwa ndi nsonga ya CFM kapena kuthamanga kwamphamvu kwambiri. Zimatanthauzidwa ndi zomwe sizikuchitika: palibe kuzimitsa kosakonzekera kwa miyezi 18 yowunikira, palibe kusalinganika kwa tsamba komwe kumayambitsa dzimbiri m'mphepete mwa nyanja yamchere, palibe kuwongolera pambuyo pa kuyimitsidwa koyambira 10,000.
Zibo Hongcheng Fan Co., Ltd. imamanga mafaniwa m'malo awo okwana 9,000 m² Zibo Blower Industrial Park—malo omwewo pomwe chigawo chilichonse chimapangidwa ndi makina, olinganiza bwino, osonkhanitsidwa, ndi kuyezetsa katundu. Palibe subcontracted msonkhano womaliza. Palibe zoletsa zamtundu wa offshore. Wokupiza aliyense amakhala ndi kachidindo ka QR kolumikizana ndi lipoti lake loyesa: piritsi la mpweya, kuthamanga kwa mawu pa 1m, kukwera kwa kutentha, ndi matalikidwe a vibration mu mm/s RMS.
Ngati polojekiti yanu yotsatira ikufuna kuyenda kwa mpweya womwe mungakhulupirire - osati kungowerengera - yambani ndi SDF mndandanda wa tunnel fan. Chifukwa m'malo otsekedwa, masekondi amawerengera. Ndipo kudalirika si mawonekedwe. Ndi maziko.
