Nā mea e pili ana i ka DTH Bit Efficiency

ʻO ka bit DTH (Down-The-Hole) e pili ana i kahi mea hana wili kūikawā i hoʻohana ʻia i ka ʻoihana mining, kūkulu hale, a me nā ʻoihana ʻaila a me ke kinoea. Hoʻolālā ʻia e hoʻopili ʻia i kahi hāmare DTH a hoʻohana ʻia i nā hana ʻeli iho-ka-hole.

Ma waho aʻe o ke koho pololei ʻana o nā māka carbide cemented, ua hoʻopili ʻia ka pono o ka drill DTH e nā kumu he nui, hiki ke ʻike nui ʻia ka drill e ka nānā pono. He ʻokoʻa ke ʻano o ka puʻu drill, a ʻokoʻa hoʻi ka ʻāpana o ka lua pahū i loaʻa i ka wā e wili ʻia ai ka drill.

1. ʻAno wili

Hoʻopili pololei ke ʻano o ka drill bit i ka ʻāpana o ka lua pahū. He polygonal ka ʻāpana o ka lua puhi o ka hapa nui o nā ʻāpana drill, ʻaʻole pōʻai. No laila, ua hoʻokumu ʻia ka ʻāpana polygonal ma muli o ka hoʻokaʻawale ʻana o ka drill bit i kekahi ʻaoʻao o ka lua pahū i ka wā e hoʻohuli ai ma kona axis. I ka wā o ke kaʻina hana wili, ʻaʻole e hoʻololi ke koʻokoʻo drill ma kahi axis paʻa akā e oscillates manuahi i loko o ka lua.

2. Na waiwai pohaku

ʻO nā waiwai pōhaku e pili ana i ka wikiwiki bit ka nui o ka viscosity, hardness, and elasticity. ʻO ka paʻa o ka pōhaku, ʻo ia ka hiki o ka pōhaku ke pale i ka haki ʻana i nā ʻāpana liʻiliʻi. Pili nā waiwai pōhaku i ka haku mele a me ka haku mele; ka liʻiliʻi a me ke ʻano o nā ʻāpana; a me ka nui, ka haku mele ʻana, a me ka makū o ka sima. He like ka viscosity o nā pōhaku paʻa a me nā pōhaku like ʻole ma nā ʻaoʻao a pau, a he ʻokoʻa ka viscosity o nā pōhaku heterogene a i ʻole nā ​​pōhaku papa ma nā ʻaoʻao a pau. ʻO ka paʻakikī o ka pōhaku, e like me ka viscosity, e hoʻoholo ʻia e ka ikaika hoʻohui ma waena o nā ʻāpana pōhaku. Eia nō naʻe, ʻo ka paʻakikī o ka pōhaku ka hiki ke pale aku i nā mea hana ʻoi e komo i loko. ʻO ka elasticity o ka pōhaku e pili ana i kona hiki ke hoʻihoʻi i kona ʻano kumu a me kona leo ma hope o ka nalowale ʻana o ka ikaika o waho e hana ana ma luna. He elastic nā pōhaku a pau. He hopena koʻikoʻi ka elasticity o ka pōhaku i ka hopena o ka drill bit.

He ʻoihana ʻo ZZBETTER Drill Bit Factory i ka noiʻi ʻepekema a kūʻai aku i nā mea hana wili pōhaku. ʻO ZZBETTER Drill Bit Factory ka mea hana nui a kūʻai aku i ka ZZBETTER series down-the-hole drill bits, drill pipes, a me lalo-the-hole drilling rigs, a hoʻomohala i nā mea hana wili pōhaku like ʻole, nā lako mīkini eli, nā mea hoʻokūkū, etc. a me DTH rigs a me DTH bits me nā pono hana kū hoʻokahi.
