Kukumba pansi pa nthaka kumafuna mpweya wabwino umene sulephera—pamene kulephera kwa mafani sikuli vuto; ndikuphwanya chitetezo. Ichi ndichifukwa chake ogwira ntchito ku migodi ku Shanxi, Inner Mongolia, ndi kudera la Southeast Asia akubwerera ku FBD mndandanda migodi fan: osati ngati chowombera wamba, koma ngati chotsimikizira kumunda, chotsimikizira kuphulika-jakisoni wotsutsana ndi axial flow of the local ventilation fan yomangidwira malo opanda ziro.
Tawona zomwe zimachitika pamene zowunikira mpweya zimakopera kuchokera m'mabulosha - osatsimikiziridwa mobisa. Makasitomala m'modzi mumsoko wa malasha wokhala ndi 8.2% ya methane adayika fani ya axial yosadziwika "yogwiritsa ntchito migodi." Inapambana mayeso a fakitale. Zinalephera pa Tsiku 17 - kugwedezeka kwamphamvu, mayendedwe adatenthedwa, ndipo nyumba yamagalimoto idasweka pansi pa njinga yamoto. Chifukwa chake? Palibe kusanja kwamphamvu pa torque yodzaza. Palibe kuyezetsa kolowera fumbi. Palibe chitsimikizo chotsutsana ndi miyezo yotsimikizira kuphulika kwa GB 3836.1–2021. Mndandanda wa FBD umapewa misampha imeneyo mwa kupanga-osati mwa kusintha.
Chifukwa Chake Counter-Rotation Sikungowonjezera Kutsatsa
Mafani ambiri a axial amazungulira rotor imodzi. Mndandanda wa FBD umagwiritsa ntchito ma rotor awiri odziyimira pawokha omwe amazungulira molunjika. Izi sizongoyerekeza - ndi zotulukapo zoyezeka: mpaka 15% kuthamanga kwamphamvu kwapang'onopang'ono pamagetsi omwewo, 8-12 dB (A) phokoso lotsika pa 3 metres, ndi pafupifupi zero axial kukankhira pamabere. Tidayezera izi mu situ pakuyesa kwa masiku 90 pa shaft yachitsulo yakuya ya 1,200-m ku Anhui. Ndi kuthamanga kwa inlet static kusinthasintha pakati pa -120 Pa ndi -210 Pa chifukwa cha kusuntha kwa ngalandeyo, kukhazikitsidwa kwa ma rotor awiri kumapangitsa kuti mpweya uziyenda mkati mwa ± 2.3% ya malo - pamene mayunitsi a rotor amodzi amayendetsa ± 9.7%.
Kukhazikika kumeneko kumabwera chifukwa cholumikizana ndi makina-osati kukonza mapulogalamu. Rotor iliyonse imakwera pamisonkhano yake yolondola kwambiri, yogwirizana ndi ≤0.03 mm chiwerengero chowerengera chowerengera (TIR). Palibe ma gearbox. Palibe kutsetsereka lamba. Kukumana kwa ma motors ongolumikizana mwachindunji, osaphulika osaphulika certification ya Ex dⅠ Mb ya zida za Gulu la M1.
Kukhalitsa Padziko Lonse: Zomwe Zimapulumuka Pansi Pansi
Zimbiri zimapha mafani mwachangu kuposa fumbi. M'migodi ya malasha yodzaza ndi sulfure, nyumba zachitsulo zosakonzedwa zimawononga mkati mwa miyezi 18. Mndandanda wa FBD umagwiritsa ntchito mafelemu otentha oviyitsa komanso zokutira za ufa wa epoxy-polyester zomwe zidavotera ISO 12944 C4. Koma kuvala kokha sikumadula - timalimbitsa madera ovuta kwambiri: ma impeller hubs amapeza zitsulo zosapanga dzimbiri 3-mm-thick; zitsulo zolowera zimakhala ndi mbale zosinthika za AR400; ndipo zomangira zonse ndi A4-80 zosapanga dzimbiri zokhala ndi anti-seize compound yoyikidwa kale.
Timayesanso kupitirira muyezo. Chigawo chilichonse chimayesedwa kwa maola 4 mosalekeza-kupopera mchere pa 35 ° C, kutsatiridwa ndi maola 72 mu 95% RH chinyezi pa 40 ° C-kenako kuyesanso ntchito mwamsanga. Ngati mpweya ukutsika kuposa 1.5%, umakanidwa. Palibe kuchotserapo. Chilango chimenecho chikufotokozera chifukwa chake mayunitsi a FBD amalemba pafupipafupi 42,000+ maola ogwirira ntchito isanayambike ntchito yayikulu - pafupifupi kuwirikiza kawiri gawo lapakati pamakampani pamiyeso yofananira.
Kuyika & Kuphatikiza: Kumene Ogulitsa Ambiri Amayima Pafupi
"Pulagi-ndi-sewero" kulibe mobisa. Mufunika kutengera ma ducting, kusinthasintha kwamagetsi, komanso kuyang'anira nthawi yeniyeni - osati chizindikiro cha CE. Mndandanda wa FBD umayenda ndi zabwino zitatu zophatikizira:
- Zosankha za mawonekedwe a duct: Standard 600 mm, 700 mm, ndi 800 mm flanges-kuphatikiza ma adapter tapered kwa cholowa 24 ″ kapena 30 ″ ma duct system
- Mphamvu zosinthika: Dual-voltage windings (380 V / 660 V) yokhala ndi kasinthidwe ka 1140 V poyikira njira zazitali zazitali.
- Zomanga za Smart-ready: Masensa omangidwa mu PT100 pama windings onse agalimoto + ma vibration transducer (4–20 mA zotuluka), zolumikizidwa ndi mawaya ku midadada yama terminal - palibe kuphatikizika kwamunda komwe kumafunikira.
Palibe zida za retrofit. Palibe kuchedwa "kulumikizana ndi gulu lathu la engineering". Izi sizowonjezera-ndizophatikizidwa ndi fakitale, zoyesedwa, ndi zolembedwa mu lipoti lotumidwa lotumizidwa ndi gawo lililonse.
Kusankha Bwino—Popanda Kungoyerekezera
Kusankha a FBD mndandanda migodi fan sizikukhudzana ndi kufananiza mphamvu zamahatchi ndi kutalika kwa ngalande. Ndi za kupanga mapu a momwe zinthu zilili zovuta kwambiri: kuchuluka kwa methane, kuchuluka kwa fumbi komwe kumayembekezeredwa (mg/m³), kusinthasintha kwa kutentha, ndi nthawi yovomerezeka yokonzekera. Ndicho chifukwa chake sitinatchule m’mabuku. Timayamba ndi dongosolo lanu la mgodi, ndondomeko ya mpweya wabwino, ndi kuwerengera kwa gasi wakale-ndi machitidwe a chitsanzo pogwiritsa ntchito ma curve ovomerezeka a CFD, osati ma chart oyenerera.
Ngati kutentha kwanu kumafika pa 45 ° C pafupipafupi, mumafunika kutchinjiriza kwa mota (Kalasi H, osati F). Ngati fani yanu imayenda maola 22/tsiku ndikuyimitsa kwa mphindi 3/kuyambira, mufunika mafunde olimba a stator ndi kuyanjana kofewa. Izi si "zosankha" -ndizosakambirana. Ndipo amawotchera mugawo lililonse la FBD asanachoke pamalo opangira Zibo Blower Industrial Park.
Kudalirika mobisa sikutheka kudzera mu redundancy. Zimamangidwa mu rotor, zopangidwira m'nyumba, zimatsimikiziridwa mu selo yoyesera, ndikutsimikiziridwa komwe kuli kofunikira - mumdima, pansi pa kupanikizika, ndi miyoyo yodalira mpweya. Ndiwo muyezo wa FBD. Osati chandamale. Osati lonjezo. Zoyambira.
