4. Mapangidwe a mpweya wabwino ndi dongosolo la dongosolo
4.1 Main mapangidwe magawo
4.1.1 Kubowola kuya. Avereji yake ndi 4.5m, ndipo kuphulika kogwira mtima ndi 4.0m.
4.1.2 Kuchuluka kwa zida zophulika. Tengani 1.8kg/m3pofukula mbali zonse, ndipo kuchuluka kwa ziboliboli pakuphulika kumodzi ndi 767kg. Kufukula kwa dzenje loyendetsa ndege kumatenga 1.8kg/m3, ndipo kuchuluka kwa bomba limodzi lophulika ndi 364kg.
4.1.3 Kutaya nthawi yopuma utsi. Kufukula kwa gawo lonse ndi maenje oyendetsa ofanana adatengedwa 20 min.
4.1.4 Kuthamanga kwa mpweya wa ma ducts apansi panthaka pa 100 mita. Tengani P100= 1.0% ~ 2.0%.
4.1.5 Pamene msewu uli ndi mpweya wabwino, mpweya wotuluka pakhomo la mpweya ndi 1.5%.
4.1.6 Mlozera wogwiritsa ntchito mpweya wa injini ya dizilo mumphangayo mutakhazikitsa chipangizo choyeretsera mpweya ndi 4.0m3/(min·kW).
4.1.7 Kutalika. Tengani kutalika kwa ngalandeyo ngati 3600m.
4.1.8 Kuwongolera kukwera kwa kukwera kwa mpweya
, kutengera kutalika kwa dera la Guanjiao ngati z=3600m, ndiye
.
4.1.9 Tengani koyeneti yolimbana ndi mikangano motsatira njira yolowera mpweya, ndiye kuti, Darcy koyefifi λ= 0.012~0.015.
4.1.10 Kuthamanga kokhazikika kwa galimoto yotayira ndi 10km/h, ndi otsetsereka pafupifupi 5° kapena pamene msewu uli wosiyana, liwiro ndi 5km/h.
4.1.11Kukana kwa mphepo kwa mpweya wolowera ndi kutuluka kwa shaft yokhazikika. Tengani Nambala 6 yokhotakhota shaft (2808m) mwachitsanzo, pamene shaft yokhotakhota ilowa mu dzenje lalikulu, zomangamanga zidzachitidwa polowera ndi kutuluka kwa Lines I ndi II motsatira, ndi nkhope zonse za 4 zogwira ntchito.
Malo ophatikizika a njira yolowera mpweya kumtunda kwa shaft yokhazikika ndi 17.1m.2, wozungulira wozungulira ndi 16.96m, ndipo m'mimba mwake wofanana ndi 4.03m. Malo ophatikizika a njira yotulutsa mpweya m'munsi mwa shaft yokhazikika ndi 22.0m.2, kozungulira kozungulira ndi 19.88m, ndipo m'mimba mwake wofanana ndi 4.43m.
4.2 Mapangidwe ndi Magawo a Dongosolo la Hybrid Ventilation Scheme mu Clapboard Roadway of Inclined Shaft
Table 4 ikuwonetsa mapangidwe ndi magawo a dongosolo la mpweya wosakanikirana mumsewu wa clapboard wa shaft iliyonse. Mwachitsanzo, mumtundu wa 6 wotsatira shaft, mtundu wa 125B-2110 wotsutsana ndi axial flow fan ungasankhidwe. Mpweya wopangidwa ndi 1800m3/ min ndipo kuthamanga kwathunthu ndi 5000Pa. , The mphamvu galimoto ndi 2 × 110kW, ndi magawo awiri liwiro lamulo.
