He 250kw mine axial flow fan, K40-8-NO26 Mine Fan, ke hoʻouna ʻia nei i nā ʻoihana mining ma Hunan Province, Kina. E hoʻohana i nā motika pahū-hōʻoia me ka volta o 380V. ʻO ke ola hana hoʻolālā o ka peʻa he 15 mau makahiki.
ʻO ke kūlana kiʻekiʻe, haʻahaʻa haʻahaʻa, ʻaʻohe humps i ka pihi hiʻohiʻona
ʻO ka hanauna hou K a me DK kaʻu mau mea hoʻopakele ikehu
1. Nānā nui
Ua hoʻolālā maikaʻi ʻia ka hanauna hou K a me DK series mine energy-saving fans ma muli o nā mea pā hoʻopakele ikehu kumu. Ma o ka hoʻomaikaʻi ʻana i ka ʻenehana a me ka hoʻomaikaʻi ʻana i ke kūkulu ʻana, ua hoʻonui ʻia kā lākou hana a ua hoʻonui ʻia ka nui o ka mīkini. ʻOi aku ka maikaʻi o kēia pūʻulu o nā mea pā, ʻoi aku ka haʻahaʻa o ka walaʻau, kahi ākea o ka hana, a me nā hopena hoʻopakele ikehu. Hoʻohui ʻia, hoʻokomo ʻia kahi mea hoʻoheheʻe kahe kahe i loko o ka cylinder peʻahi nui, e hoʻopau ana i nā humps i ka pihi hiʻohiʻona, e hōʻoia ana i ka hana paʻa o ka peʻahi ma lalo o nā kūlana kūʻē.
No ka hoʻonui ʻana i ka pae hana o kēia pūʻulu o nā mea pā a hoʻokō i nā pono o nā mines nui ʻole, a me nā mea liʻiliʻi liʻiliʻi ʻole, i hiki i nā ʻupena ventila me nā haʻahaʻa haʻahaʻa, kiʻekiʻe, kiʻekiʻe a me ka nui, ka liʻiliʻi, ka liʻiliʻi liʻiliʻi e hiki ke koho i nā mea pā nui, nā mea kōkua kōkua, a me nā mea hoʻokele multi-stage e hana ana i ka ʻoihana kiʻekiʻe, ua hoʻohana kēia pūʻulu pā i ʻelua ratios hub (0.45 a me ʻelua ʻāpana), ʻo ia hoʻi. K40, K45 a me DK40, DK45. A hoʻohana ʻo K40 i nā motika 4, 6, a me 8-pole no ʻekolu mau māmā, hoʻohana ʻo K45 i nā motika 4 a me 6-pole no ʻelua mau māmā, a hoʻohana ʻo DK40 a me DK45 i nā motika 6 a me 8-pole no ʻelua mau māmā.
Ma kēia ala, ma ka "hoʻohui ʻana" i kēlā me kēia mīkini nui me ʻelua hub ratios, ʻelua ʻano hoʻolālā, a me ʻekolu mau wikiwiki i kekahi ala, ʻo kēia pūʻulu o nā mea pā he 93 mau kikoʻī.
Hōʻike ʻia ka laulā hana a me nā ʻāpana ʻenehana nui o ka hanauna hou K series a me DK series mine hoʻōla ikehu me ka ʻole o ka humps i hōʻike ʻia ma ka Papa 2 a me ka Papa 3. ʻO nā paona kuhikuhi i helu ʻia ma ka papa ʻaina me ke kaumaha o ka mīkini a me ka diffuser o ka mīkini holoʻokoʻa.
Hōʻike ʻia nā kiʻi hoʻolālā a me nā papa nui o nā mea pā K40 a me K45 ma ke Kiʻi 6 a me nā Papa 6 a me 7.
ʻO ke ʻano hōʻike hoʻohālike (laʻana) o ka hanauna hou K a me DK series mine hoʻopakele ikehu penei: K 40–4 №.15
ʻO ka helu kumu hoʻohālike ʻo 15,
("DJK" e hōʻike ana i ka māhoe-screw type mining fan) (ʻo ia hoʻi ke anawaena o ka huila hana D = 15dr;
