ʻO Kaishan KG420S Surface DTH Drilling Rig — Dual Power Diesel-Electric Versatility no ka Hana Kaumaha

ʻO ka Kaishan KG420S kahi mīkini wili DTH ʻano hoʻokaʻawale mana e kū nei no kāna ʻōnaehana mana pālua hou. Ma ka hoʻohui ʻana i kahi ʻenekini diesel kiʻekiʻe a me kahi motika uila kiʻekiʻe, hāʻawi kēia mīkini i ka maʻalahi o ka hana a me ka mālama kālā. Kūkulu ʻia no ka wili ʻana i ke anawaena nui a me nā noi lua hohonu, ʻo ka KG420S ka hopena hope loa no nā kahua mining a me nā kahua kūkulu kahi i hiki ʻole ke kūkākūkā ʻia ka mana, ka versatility, a me ka hana kaumaha.

ʻO ka hiʻohiʻona koʻikoʻi o ka KG420S ʻo ia kāna mau ʻōnaehana mana kūʻokoʻa ʻelua: kahi ʻenekini diesel Yuchai 58KW a me kahi motika uila 55KW YE3. Hiki ke hoʻokele ʻokoʻa ʻia kēia mau ʻōnaehana, e ʻae ana i ka rig e holo ma ka diesel i ka wā e neʻe ai a i ʻole ma nā wahi mamao, a hoʻololi i ka mana uila ke loaʻa nā pono hana ma ka pūnaewele. ʻO kēia mana mana pālua, i hāʻawi ʻia e Shaanxi Kaishan, e hōʻemi nui ana i nā kumukūʻai hana a me nā pae walaʻau me ka hāʻawi ʻana i kahi kākoʻo hilinaʻi i nā papahana lōʻihi.

Ua kūkulu ʻia kēia mea hana ma luna o kahi chassis hana kaumaha e hōʻike ana i kahi ala hoʻopaʻa pelu a me kahi motika hele plunger, e hāʻawi ana i kahi kahua paʻa no ka ʻeli ʻana i ka torque kiʻekiʻe. ʻO ka ʻōnaehana hoʻokele 4-huila a me ka hiki ke piʻi i 30-degere e hōʻoiaʻiʻo e hiki iā ia ke hōʻea i nā kūlana noho paʻakikī loa. No ka lawelawe ʻana i ka 5000N·m nui o ka torque, ua lako ka mea hana me kahi ʻōnaehana motika wili pālua, e hiki ai iā ia ke ʻeli i nā lua a hiki i 152mm ke anawaena ma o ka pōhaku paʻakikī (f=6-20).

Ua hana ʻia nā mīkini wili o ka KG420S no ka huahua. Loaʻa iā ia kahi ikaika hāpai nui 40KN a me kahi cylinder aila me ka ʻōnaehana hānai kaulahao wili, i hoʻolālā ʻia e lawelawe i nā hāmare DTH 4″ a me nā koʻokoʻo wili nui. ʻO ka pitch i hoʻonui ʻia a me nā cylinder lima hāpai e ʻae i ke kūlana boom pololei, ʻoiai ʻo ka uku 970mm e hōʻoiaʻiʻo ana i ka paʻa o ke alahao alakaʻi ma ke kaʻina hana wili.

ʻIke ʻia ke kūpaʻa ma nā ʻano āpau o KG420S. Mai ka hale mānoanoa a hiki i ka cylinder hāpai a me ke kaulahao i hoʻoikaika ʻia, ua kūkulu ʻia kēia mīkini e ola i nā wahi ʻeli pōhaku ʻino loa. ʻO kona hiki ke wili i nā lua ākea a hiki i 2850mm a me nā lua kū pololei a hiki i ka hohonu o 25 mika e hoʻolilo iā ia i mea maʻalahi loa no nā koi papahana like ʻole, mai ka hana ʻeli lua ākea a hiki i ka hana hoʻokumu nui.

No ka hoʻopuka nui loa, pono e hoʻopili ʻia ka KG420S me nā mea hoʻopili wili kiʻekiʻe ʻo Kaishan e like me ka KSCY570/12-550/15, LGCY17/18-18/15T, a i ʻole ka KSCY650/20-700/17T. Hāʻawi kēia hui pū ʻana i ka nui o ka ea (13-20 m³/min) e pono ai e hoʻoikaika i nā hāmare 4″ a hoʻomaʻemaʻe pono i nā nui nui o nā ʻokiʻoki, e hoʻolilo ana i ka KG420S i koho koʻikoʻi no ka ʻeli ʻana i ka hana kiʻekiʻe.
