ʻO Kaishan KG420TH Surface DTH Drilling Rig — Hōʻiliʻili lepo kiʻekiʻe no ka hana maʻemaʻe

ʻO ka Kaishan KG420TH kahi mīkini wili DTH ʻano hoʻokaʻawale hana kiʻekiʻe, i hoʻolālā ʻia no nā mea hana e hoʻokau mua i ka mālama ʻana i ke kaiapuni me ka ʻole o ka mōhai ʻana i ka mana wili. Ma muli o ka paepae KG420T i hōʻoia ʻia, ʻo ka hōʻailona "H" e hōʻike ana i ka hoʻohui ʻana o kahi ʻōnaehana hōʻiliʻili lepo kaumaha. Ma ke ʻano he mea hoʻolaha kūhelu o ka Kaishan Group, lawe mai ʻo Shaanxi Kaishan iā ʻoe i kahi mīkini i kākoʻo ʻia e kahi kokoke i ʻehiku mau makahiki o ka hoʻoilina ʻoihana a me ka ʻenekinia papa honua.

ʻO ka mea hoʻokaʻawale nui o ka KG420TH ka mea hōʻiliʻili lepo QZA-120 maʻamau, me kahi pūʻulu kānana 12 e hopu pono ana i nā particulates maikaʻi i ka wā o ke kaʻina hana ʻeli. No nā wahi e pono ai ka kānana kiʻekiʻe aʻe a i ʻole ke ʻeli ʻana i nā lua ma mua o 130mm, loaʻa kahi mea hōʻiliʻili QZA-140 koho me 16 mau kānana. ʻAʻole wale kēia ʻōnaehana e hōʻoia i kahi kaiapuni olakino no ka poʻe hana akā pale pū kekahi i nā ʻāpana o loko o ka rig mai ka lepo abrasive, e hoʻolōʻihi ana i ke ola lawelawe o ka ʻenekini a me nā ʻōnaehana hydraulic.

No ka hoʻokō ʻana i nā koi mana hou aʻe o ka ʻōnaehana hōʻiliʻili lepo, ua lako ka KG420TH me kahi ʻenekini Yuchai YC4DK100-T304 i hoʻomaikaʻi ʻia. Me ka hāʻawi ʻana i 73.5KW ma 2200rpm, hāʻawi kēia ʻenekini i ka lumi poʻo e pono ai e holo i nā hydraulics kiʻekiʻe a me ka vacuum lepo i ka manawa like, e hōʻoiaʻiʻo ana e mau ana nā helu komo ʻana i loko o ka pōhaku paʻakikī loa (f = 6-20).

Ma ke ʻano o ke ʻano, hōʻike ka rig i kahi hale mānoanoa a me kahi ʻōnaehana ala pelu i hoʻoikaika ʻia. ʻO ka hoʻokomo ʻana o kahi motika hele plunger kiʻekiʻe-torque a me kahi hoʻonohonoho hoʻokele 4-huila e hiki ai i ka mīkini 5350KG ke neʻe ma waena o ka ʻāina paʻakikī a piʻi i nā pae a hiki i ka 30°. Hōʻoia ka ʻōnaehana pae ala (± 10°) e mālama ka rig i kahi kūlana kū pololei a kihi paha ma nā papahele lua pōhaku ʻaʻole like, he mea nui ia no ka pololei o ka lua.

ʻO ka hiki ke ʻeli ʻana he kiʻekiʻe loa ia, me ka torque rotary o 3500N·m a me ka hahau hānai 3175mm i hoʻokele ʻia e kahi cylinder aila kaumaha a me ka mīkini kaulahao wili. Hoʻokele maʻalahi ka rig i nā lua Φ90-152mm, e lilo ia i mea hana versatile no ka pahū ʻana i ka bench i ka mining a me nā kumu kūkulu i ke kūkulu ʻana. ʻAe nā pae hoʻoponopono beam a me boom i ka maʻalahi kupaianaha, me ka ʻeli ʻana i ka pae ma nā kiʻekiʻe haʻahaʻa e like me 350mm.

Manaʻo ʻo Shaanxi Kaishan e hoʻopili i ka KG420TH me kā mākou mau compressors ea wili lawe lima KSCY a i ʻole LGCY series e hōʻoia i ka lako mau o ka ea 13-20m³/min. Hāʻawi kēia hui pū ʻana i ka mana "flushing and crushing" e pono ai no nā hana DTH kūpono. Me ka paepae R&D honua o Kaishan, me kā mākou kikowaena loea ma Seattle, hōʻike ka KG420TH i ka piko o ka ʻenehana wili ʻilikai hou a aloha i ke kaiapuni.
