Xov khawm cov khoom thiab cov khoom siv taper yog ob hom kev xyaum siv hauv ntau yam kev siv drilling, tshwj xeeb hauv kev tsuas, kev tsim kho, thiab kev tshawb nrhiav kev lag luam. Lawv tau tsim los tsim cov qhov nyob rau hauv ntau hom pob zeb formations, thiab lawv cov kev tsim tshwj xeeb ua rau lawv haum rau kev sib txawv drilling dej num. Cia peb tshawb nrhiav txhua yam kom ntxaws ntxiv:
Xov Button Bits:Xov khawm cov khoom siv feem ntau yog siv rau hauv ntau txoj kev drilling, suav nrog cov teb drilling thiab rauj sab saum toj. Lawv yog cov yam ntxwv ntawm lawv cov threaded kev twb kev txuas mus rau lub laum pas nrig los yog laum yeeb nkab, uas tso cai rau kom yooj yim txuas thiab tshem tawm ntawm lub drilling rig. Cov threaded kev twb kev txuas kuj ua kom muaj kev ruaj ntseg haum, txo qhov yuav ua rau me ntsis tau daig hauv lub qhov.
Cov xov khawm cov khoom muaj hardened, spherical nyees khawm (ntxig) ua los ntawm tungsten carbide uas yog embedded rau hauv me ntsis lub crown. Cov nyees khawm no tuaj nyob rau hauv ntau yam duab, qhov ntau thiab tsawg, thiab kev teeb tsa, nyob ntawm seb hom pob zeb raug drilled thiab qhov drilling. Cov nyees khawm yog tsim los tiv thaiv cov abrasive thiab muaj kev cuam tshuam zoo ntawm pob zeb drilling, kom ntseeg tau tias kev ua haujlwm zoo thiab ua haujlwm zoo.
Taper khoom:
Taper khoom feem ntau yog siv rau hauv cov txheej txheem drilling hu ua tapered drilling lossis taper drilling. Cov txheej txheem no suav nrog kev siv ntau txoj kab uas hla loj dua laum cov khoom kom nthuav dav lub qhov. Taper khoom yog tshwj xeeb tshaj yog haum rau drilling qhov rau blasting lub hom phiaj hauv mining thiab kev tsim kho.
Taper khoom muaj ib tug conical zoo nrog ib tug maj mam nce nyob rau hauv txoj kab uas hla ntawm lub ntsis lub ntsis mus rau lub hauv paus. Lub tapered tsim tso cai rau kom yooj yim tshem tawm ntawm me ntsis ntawm lub qhov thiab txo qhov kev pheej hmoo ntawm jamming los yog sticking. Zoo li xov khawm cov khoom, taper khoom kuj tseem muaj cov nyees khawm tungsten carbide ntawm lawv lub ntsej muag drilling los txhim kho kev ua haujlwm zoo thiab ua haujlwm ntev.
Ob lub xov khawm cov khoom thiab cov khoom taper tuaj nyob rau hauv ntau qhov ntau thiab tsawg thiab kev teeb tsa kom haum raws li qhov xav tau sib txawv. Qhov kev xaiv ntawm ob yog nyob ntawm cov yam xws li hom pob zeb raug drilled, txoj kev drilling, qhov yuav tsum tau muaj txoj kab uas hla, thiab qhov tshwj xeeb drilling tej yam kev mob.
Nyob rau hauv cov ntsiab lus, xov khawm cov khoom yog tus cwj pwm los ntawm lawv cov threaded kev twb kev txuas thiab spherical tungsten carbide nyees khawm, haum rau rotary thiab sab saum toj rauj drilling txoj kev. Taper cov khoom, ntawm qhov tod tes, muaj cov duab conical thiab feem ntau siv rau hauv cov txheej txheem drilling rau kev siv tsuas thiab kev tsim kho. Ob hom laum khoom ua si lub luag haujlwm tseem ceeb hauv ntau yam kev siv drilling los ntawm kev muab lub qhov zoo thiab ua haujlwm zoo hauv cov pob zeb sib txawv.
