Ngā Tohu Hua

Ko te Kaishan KG420TH he mīhini keri DTH momo-wehewehe, he mahi teitei, he mana-tīhi, i hangaia mō ngā kaiwhakahaere e aro nui ana ki te taiao me te kore e whakaiti i te mana keri. I runga i te tūāpapa KG420T kua whakamātauhia, ko te tohu "H" e tohu ana i te whakaurunga o tētahi pūnaha kohikohi puehu taumaha. Hei kaituku mana o te Rōpū Kaishan, ka kawea mai e Shaanxi Kaishan ki a koe tētahi mīhini e tautokona ana e tata ki te whitu tekau tau o te taonga tuku iho ahumahi me te hangarau o te ao.

Ko te mea matua e rerekē ai te KG420TH ko te kaikohi puehu QZA-120 paerewa, e whakaatu ana i tētahi huinga tātari-12 e hopu pai ana i ngā matūriki iti i te wā e keri ana. Mō ngā wāhi e hiahia ana kia nui ake te tātari, ina keri ana rānei i ngā kōhao neke atu i te 130mm, kei te wātea he kaikohi QZA-140 whiriwhiri me ngā tātari 16. Ehara i te mea ka whakarite noa tēnei pūnaha i tētahi taiao hauora mō te kapa engari ka tiaki hoki i ngā wāhanga o roto o te waka mai i te puehu whakakoi, ka roa ake te roa o te mahi a te miihini me ngā pūnaha waipēhi.

Hei whakatutuki i ngā whakaritenga mana tāpiri o te pūnaha kohikohi puehu, kua rite te KG420TH ki tētahi miihini Yuchai YC4DK100-T304 kua whakapai ake. Mā te tuku i te 73.5KW i te 2200rpm, ka whakaratohia e tēnei miihini te wāhi matua e tika ana hei whakahaere i ngā waipēhi pēhanga-tiketike me te korehau puehu i te wā kotahi, kia mau tonu ai ngā reiti urunga ahakoa i roto i te toka tino mārō (f=6-20).

Ko te hanganga o te taputapu he whare matotoru, he pūnaha ara anga takai kua whakapakaritia. Mā te whakaurunga o tētahi mōtini hikoi pūwero taipana-teitei me te whakaritenga taraiwa-4-wira ka taea e te mīhini 5350KG te neke haere i runga i te whenua paripari me te piki i ngā pari tae atu ki te 30°. Mā te pūnaha whakataurite ara (±10°) ka mau tonu te taputapu i tētahi tūranga poutū, koki rānei i runga i ngā papa rua koretake, he mea nui tēnei mō te tika o te poka.

Kei te taumata teitei tonu te kaha o te keri, me te taipana hurihuri o te 3500N·m me te whiu whāngai 3175mm e peia ana e te rango hinu taumaha me te mekameka roera. Ka taea e te taputapu te whakahaere i ngā kōhao Φ90-152mm me te ngāwari, ka waiho hei taputapu maha-whakamahinga mō te pupuhi papa i roto i te keri me ngā turanga hanganga i roto i te hanganga. Mā ngā awhe whakatikatika kurupae me te pūmau ka taea te tino ngāwari, tae atu ki te keri whakapae i ngā teitei iti iho i te 350mm.

E taunaki ana a Shaanxi Kaishan kia honoa te KG420TH me ā mātou pūwero hau tīwiri kawe raupapa KSCY, LGCY rānei, kia mau tonu ai te tuku hau 13-20m³/min. Mā tēnei huinga ka puta te mana "horoi me te kuru" e hiahiatia ana mō ngā mahi DTH whai hua. Me te tapuwae R&D o Kaishan puta noa i te ao, tae atu ki tō mātou pokapū hangarau kei Seattle, ko te KG420TH te tihi o te hangarau keri mata hou, hoa-taiao.
