Lub pob zeb laum me ntsis yog ib qho cuab yeej tseem ceeb hauv kev ua haujlwm engineering. Nws tuaj yeem cuam tshuam cov pob zeb zoo, ua kom cov phiaj xwm ua tiav thiab txhim kho kev ua haujlwm. Txawm li cas los xij, ntau hom pob zeb laum khoom muaj nyob rau hauv kev ua lag luam, txhua tus tsim los ua kom haum rau cov kev khiav hauj lwm sib txawv thiab sib txawv ntawm cov pob zeb hardness. Yog li, xaiv qhov tsim nyog pob zeb laum me ntsis rau koj cov kev xav tau tshwj xeeb dhau los ua qhov kev txiav txim siab tseem ceeb.
Ntxig Bits: Kuj hu ua khawm khoom, cov no yog cov feem ntau siv laum khoom. Lawv feature tungsten carbide inserts nias rau hauv lub ntsis steel lub cev. Ntxig cov khoom muaj ntau yam thiab haum rau ntau hom pob zeb.
Tricone khoom: Cov khoom no muaj peb rotating cones nrog cov hniav los yog inserts. Lawv muaj txiaj ntsig zoo hauv kev drilling los ntawm nruab nrab mus rau cov pob zeb nyuaj thiab feem ntau siv hauv cov roj thiab roj drilling.
Pob zeb diamond khoom: Pob zeb diamond cov khoom siv rau drilling los ntawm cov pob zeb nyuaj heev xws li granite, basalt, thiab lwm yam pob zeb tsis zoo. Lawv muaj cov pob zeb diamond qib kev lag luam kos nyob rau hauv me ntsis matrix kom zom los ntawm cov pob zeb nyuaj.
PDC (Polycrystalline Pob Zeb Diamond Compact) Khoom: PDC cov khoom siv ruaj khov, loj, qib kev lag luam pob zeb diamond cutters (polycrystalline pob zeb diamond compact) los zom los ntawm cov pob zeb tsim. Lawv muaj txiaj ntsig zoo hauv kev drilling los ntawm softer formations xws li shale thiab sandstone.
Drag Bits: Cov khoom no tau kho cov tungsten carbide los yog pob zeb diamond cutters thiab raug rub los ntawm lub ntsej muag pob zeb los tsim ib lub borehole. Lawv feem ntau yog siv rau hauv cov qauv softer xws li av nplaum, xuab zeb, thiab mos limestone.
Chisel Bits: Chisel khoom muaj lub tiaj tus, chisel-shaped txiav ntug thiab yog siv rau drilling los ntawm cov pob zeb mos mus rau nruab nrab-nyuaj. Lawv ua haujlwm tau zoo hauv kev ua haujlwm drilling qhov twg yuav tsum tau nkag siab zoo.
Hla Bits: Hla cov khoom muaj lub ntsej muag lossis X-shaped txiav ntug thiab feem ntau yog siv rau drilling hauv cov pob zeb nyuaj. Lawv feem ntau siv rau hauv kev siv mining thiab kev tsim kho.
Kauj ruam Bits: Cov kauj ruam me me muaj cov kauj ruam profile nrog cov kab uas loj dua, tso cai rau kev drilling ntawm qhov sib txawv. Lawv feem ntau siv nyob rau hauv quarrying thiab kev tsim kho tej yaam num.
