ʻO ka hoʻokaʻawale ʻana o ka lanahu a me kāna hoʻohana ʻana he aha

I kēia manawa, hoʻohana maʻamau ʻia ka hana hoʻoheheʻe lanahu i ʻekolu mau waiwai, ua māhele ʻia ka ikaika i ʻelua ʻāpana, TYPE I no ka wili pōhaku palupalu, ʻano II no ka pōhaku paʻa a me ka wili pōhaku paʻa.Me ka wikiwiki o ka hoʻoheheʻe ʻana, ka uhi milling ākea, ka mālama manawa, ka mālama ʻana i ka hana, ka maʻalahi maʻalahi, ka lōʻihi a me nā ʻano ʻē aʻe.Hoʻohana ʻia ka ʻāpana lanahu i ka ʻeli ʻana i ka lanahu maka, ke alanui lanahu paʻakikī a me ka pōhaku lanahu.Ma lalo e Zhengzhou nahele ʻoihana xiaobian e hoʻolauna i ka hoʻokaʻawale ʻana a me ka hoʻohana ʻana i ka drill lanahu.

1. ʻO nā kikoʻī a me nā hiʻohiʻona o nā pahu drill lanahu
Hoʻokaʻawale ʻia nā kikoʻī a me nā hiʻohiʻona i ka ф 28mm, ф 30mm, ф 32mm, ф 38mm, ф 42mm e like me ke anawaena o ka nui ʻēheu ʻelua.

2. Hoʻokaʻawale ʻana i nā ʻāpana drill lanahu
Wahi a ke ʻano hana ʻaʻole like, hiki ke hoʻokaʻawale ʻia ka puʻu lanahu i ka hoʻāʻo maloʻo a me ka hoʻāʻo wai ʻelua.ʻO ka bit hoʻāʻo maloʻo kahi ʻuʻuku ʻaʻole e hāʻawi i ka wai lepo a ʻaʻohe ona mana hoʻolako palekana i ke kaʻina hana wili holoʻokoʻa.Wet test bit: ʻo ka bit me ka wai lepo i hoʻolako ʻia i ke kaʻina hana wili a pau a me kahi ala palekana no ka lako mana.Wahi a nā mea ʻēheu ʻelua, ʻaʻole like ia, ua māhele ʻia ka ʻāpana lanahu i ka bit cutter carbide a me ka bit composite sheet (PDC) bit.

3, ka hoʻohana nui o ka lanahu drill
Hoʻokomo ʻia i loko o ka wili kemika lanahu, ke kī i ka palupalu – paʻa pōhaku hoʻoikaika anchor bolt support hole drilling.Hoʻohana maʻamau ia ma ke ala lanahu me ka ikaika pōhaku F ≤8, ʻoi aku ka nui ma ka hana kākoʻo bolt o ke ala lanahu, hiki iā ia ke wili i ka lua heleuma o ka pahu pahu.

Ma Kina, ua loaʻa i ka māla lānahu nā hiʻohiʻona penei: ʻo ka mua, ka mākeke mākeke, no ka mea, hoʻohana ʻia ka bit lanahu i ka ʻoihana wili lanahu, ʻoi aku ka nui o ka waena a me lalo o ka noi;ʻO ka lua, ʻoi aku ka nui o ka nui o nā ʻoihana hana, a he liʻiliʻi ka nui o ka hana, ʻoi aku ka laha, a haʻahaʻa ka ʻoihana.

Aia ma luna aʻe "he aha ke ʻano o ka ʻāpana lanahu a me kona hoʻohana ʻana?"Manaʻo wau hiki iaʻu ke kōkua iā ʻoe.Inā makemake ʻoe e haku i ka ʻike o nā mea hana mining ʻē aʻe, hiki iā ʻoe ke hoʻolohe i kēia pūnaewele, akā e nīnau pū i kā mākou lawelawe mea kūʻai aku pūnaewele, hana mākou i kā mākou maikaʻi loa e lawelawe iā ʻoe.
