Izimayini ezingaphansi komhlaba zidinga umoya omncane ongantengantengi—lapho ukwehluleka kwabalandeli kungeyona into ephazamisayo; kungukwephulwa kwezokuphepha. Kungakho abasebenzi bezimayini eShanxi, Inner Mongolia, naseNingizimu-mpumalanga ye-Asia belokhu bebuyela FBD Series Mining fan: hhayi njengesivutheli esijwayelekile, kodwa njengesivutheli sendawo esifakazelwe, esifakazelwa wukuqhuma, umjovo ophikisana ne-axial ojikelezayo wokugeleza komoya wasendaweni eyakhelwe izindawo ze-zero-margin.
Sibonile ukuthi kwenzekani lapho izici zokungenisa umoya zikopishwa ezincwajaneni—aziqinisekiswa ngaphansi komhlaba. Iklayenti elilodwa kumthungo wamalahle onokugxiliswa kwe-methane engu-8.2% lifake i-axial fan engaqinisekisiwe elinganiselwe "ukuze isetshenziswe ezimayini." Iphumelele izivivinyo zasefekthri. Yehlulekile ngoSuku lwe-17—ukundindizela kwe-spiked, ama-bearings ashise ngokweqile, futhi izindlu zezimoto zaqhekeka ngaphansi kwamabhayisikili ashisayo. Imbangela? Akukho ukulinganisa okuguquguqukayo ku-torque yokulayisha okugcwele. Akukho ukuhlolwa kokungena kothuli okulingiswayo. Akukho ukuqinisekiswa okuqhathaniswa nezindinganiso zokuvikela ukuqhuma kwe-GB 3836.1–2021. Uchungechunge lwe-FBD lugwema lezo zingibe ngokuklama—hhayi ngokulungisa.
Kungani I-Counter-Rotation Ingeyona Ijargon Yokuthengisa Nje
Abalandeli abaningi be-axial baphotha i-rotor eyodwa. Uchungechunge lwe-FBD lusebenzisa ama-rotor amabili aqhutshwa ngokuzimele azungeza ezinhlangothini eziphambene. Lokhu akuwona ukusebenza kahle kwethiyori—umphumela olinganisekayo: kufika ku-15% ingcindezi emile ephakeme ngokudonsa amandla afanayo, 8–12 dB(A) umsindo ophansi ngamamitha angu-3, kanye ne-axial thrust eseduze neqanda kumabheringi. Silinganise lokhu ku-situ phakathi nesivivinyo sezinsuku ezingu-90 endaweni yensimbi ejulile engu-1,200-m-m e-Anhui. Ngomfutho we-inlet static oguquguqukayo phakathi -120 Pa kanye -210 Pa ngenxa yokuguquguquka ukumelana nomhubhe, ukusethwa kwerotha ekabili kugcine ukugeleza komoya ngaphakathi ± 2.3% we-setpoint-ngenkathi eqhudelana amayunithi erotha eyodwa akhukhuleka ± 9.7%.
Lokho kuzinza kuvela ekuvumelaneni komshini—hhayi ukulungiswa kwesofthiwe. I-rotor ngayinye igibela umhlangano wayo wokunemba okuphezulu, oqondaniswe nokuthi ≤0.03 mm inani lokufunda lenkomba (TIR). Awekho ama-gearbox. Akukho ukushelela kwebhande. Umhlangano wamamotho ahlanganiswe ngqo nje, angaqhumi, Isitifiketi se-Ex dⅠ Mb semishini yeSigaba M1.
Ukuqina Kwezwe Kwangempela: Yini Esinda Ngaphansi Komhlaba
Ukugqwala kubulala abalandeli ngokushesha kunothuli. Ezimayini zamalahle anothe ngesulfure, izindlu zensimbi ezingakalungiswa zigqwala ngaphansi kwezinyanga eziyi-18. Uchungechunge lwe-FBD lusebenzisa amafreyimu ashisayo adiphu kanye ne-epoxy-polyester powder coating elinganiselwe ku-ISO 12944 C4. Kodwa ukugqoka kukodwa akusindisi-siqinisa izindawo zokucindezeleka ezibucayi: ama-impeller hubs athola ama-3-mm-thick stainless steel liners; ama-inlet cones afaka amapuleti okugqoka e-AR400 ashintshwayo; futhi zonke izibophelelo ziyi-A4-80 ezingenasici nenhlanganisela yokulwa nokubamba esetshenziswe ngaphambili.
Siphinde sihlole ngaphezu kwezinga. Iyunithi ngayinye ihlolwa ngokuqhubekayo amahora angu-4 ngesifutho sikasawoti ku-35°C, kulandelwa amahora angu-72 kumswakama we-RH ongu-95% ku-40°C—bese kubuye kuhlolwe ukusebenza kabusha. Uma ukugeleza komoya kwehla ngaphezu kuka-1.5%, kuyenqatshwa. Akukho okuhlukile. Leso siyalo sichaza ukuthi kungani amayunithi e-FBD evamise ukungena amahora okusebenza angu-42,000+ ngaphambi kwesevisi yokuqala enkulu—acishe aphindeke kabili i-midian yemboni yemijikelezo yemisebenzi efanayo.
Ukufakwa Nokuhlanganiswa: Lapho Abathengisi abaningi Bema Kafushane
"I-plug-and-play" ayikho ngaphansi komhlaba. Udinga ukuhambisana kwamapayipi, ukuguquguquka kwamandla kagesi, nokuqapha ngesikhathi sangempela—hhayi nje umaki we-CE. Uchungechunge lwe-FBD luhamba ngezinzuzo ezintathu eziyinhloko zokuhlanganisa:
- Izinketho zesixhumi esibonakalayo se-duct: Ama-600 mm ajwayelekile, 700 mm, kanye nama-flange angu-800 mm—kanye nama-adaptha agcizelelwe ngokwezifiso wesistimu yamapayipi angu-24″ noma angu-30″
- Ukuzijwayeza kwamandla: Amawindi ama-Dual-voltage (380 V / 660 V) anokucushwa okungakhethwa okungu-1140 V ekufakweni okuhamba ibanga elide
- I-smart-ready ready architecture: Izinzwa ezakhelwe ngaphakathi ze-PT100 kuwo womabili ama-motor windings + vibration transducer (okuphumayo okungu-4–20 mA), okuxhunywe ngentambo kusengaphambili kumabhulokhi wetheminali—akukho kuhlanganisa kwenkambu okudingekayo
Awekho amakhithi okubuyisela emuva. Akukho ukubambezeleka kokuthi "thintana nethimba lethu lonjiniyela". Lezi akuzona izengezo—zihlanganiswe nefekthri, zihloliwe, futhi zibhalwe embikweni wokugunyazwa othunyelwa ngeyunithi ngayinye.
Ukwenza Ukukhetha Okulungile—Ngaphandle Kokuqagela
Ukukhetha i FBD Series Mining fan ayikona ukufanisa amandla ehhashi nobude bomhubhe. Imayelana nokwenza imephu yesimo sakho esibi kakhulu: amazinga aphezulu e-methane, ukulayisha uthuli okulindelekile (mg/m³), ukushintshashintsha kwezinga lokushisa, kanye nesikhathi sokuphumula esivumelekile sokulungiswa. Yingakho singacaphuni kumakhathalogi. Siqala ngohlelo lwemayini yakho, uhlelo lokungenisa umoya, nokufundwa kwegesi okungokomlando—kanye nokusebenza okuyimodeli kusetshenziswa amajika efeni aqinisekisiwe yi-CFD, hhayi amashadi ahlongoziwe.
Uma izinga lokushisa lomoya owuthathayo lihlala lifinyelela ku-45°C, udinga ukufakwa kwezimoto okuncishisiwe (Ikilasi H, hhayi F). Uma ifeni yakho isebenza amahora angu-22/ngosuku nemijikelezo eyimizuzu emi-3 yokuma/yokuqala, udinga amawindi e-stator aqinisiwe kanye nokuhambisana kokuqala okuthambile. Lokhu akuzona "izinketho" -akunakuxoxisana. Futhi zibhakwa kuwo wonke amayunithi e-FBD ngaphambi kokuthi isuke endaweni yokukhiqiza iZibo Blower Industrial Park.
Ukwethembeka ngaphansi komhlaba akuzuzwa ngokungasebenzi. Yakhelwe ku-rotor, yafakwa endlini, yaqinisekiswa esitokisini sokuhlola, futhi yafakazelwa lapho ibaluleke kakhulu—ebumnyameni, ngaphansi kwengcindezi, ngezimpilo ezincike ekugelezeni komoya. Lokho kuyindinganiso yochungechunge lwe-FBD. Akuyona ithagethi. Akusona isithembiso. Isisekelo.
