Ntau hom Mining Thiab Drilling Bits

Mining thiab zoo drilling cov khoom yog qhov tho txawv cov khoom uas tho los ntawm thiab nkag mus rau cov ntaub ntawv mos thiab tawv pob zeb. Lawv yog siv nyob rau hauv mining, zoo drilling, quarrying, tunneling, kev tsim kho, geological tshawb nrhiav, thiab blasting daim ntaub ntawv.

Mining thiab zoo drilling me ntsis feem ntau feature ib tug threaded kev twb kev txuas rau kev txuas mus rau ib tug drillstring thiab ib tug hollow lub cev los ntawm kev xyaum cov kua yog circulated. Drilling kua yuav tsum tau tshem tawm cov laum cuttings, txias me ntsis, thiab stabilize lub borehole phab ntsa. Hom ntawm qhov zoo drilling me ntsis muaj xws li cov hauv qab no:

Tri-cone los yog cov menyuam cov khoommuaj peb tus hniav cones, txhua tus nrog lub kaum sab xis ntawm cov ntawv xov xwm pitched rau ntawm tus me ntsis tus thawj axis. Lub kaum sab xis ntawm phau ntawv xov xwm raug hloov kho raws li qhov nyuaj ntawm kev tsim. Cov hniav ntawm txhua lub khob mesh tiv thaiv ib leeg kom dhuav los ntawm cov khoom hauv ntiaj teb. Lub ntsis yog tsav los ntawm qhov hnyav-on-ntsis (WOB) thaum raug rub los ntawm kev ua haujlwm ntawm lub taub hau laum.

Down-the-qhov (DTH) rauj khoomyog siv nrog Down-the-qhov hammers rau drilling qhov los ntawm ntau hom pob zeb. Ua ke nrog DTH hammers, laum rauj cov khoom yog tsim los nrog ib tug splined tsav rau rotating me ntsis hauv av. DTH cov khoom yog tsau-lub taub hau khoom uas muaj conical los yog chisel me ntsis inserts raws li nyob rau hauv ib tug matrix txog lub laum ntsis taub hau. Lub taub hau configuration ntawm me ntsis tej zaum yuav convex, concave, los yog tiaj tus.

PDC cov khoomnrog polycrystalline pob zeb diamond compact (PDC) inserts yuav raug xa mus rau raws li PDC khoom. Tsis zoo li cov khoom siv tricone, PDC laum cov khoom yog ib lub cev uas tsis muaj qhov txav mus los thiab ua kom tiav; txhua qhov me me yog tsim hauv tsev rau kev ua tau zoo, sib xws thiab kev cia siab. Xaiv Matrix lossis cov hlau muaj zog kom haum rau cov ntawv thov sib txawv.

Khawm khoomyog tib yam nrog DTH cov khoom tsau-lub taub hau cov khoom uas muaj conical lossis chisel me ntsis ntxig rau hauv ib qho matrix txog lub taub hau laum. Lub taub hau configuration ntawm me ntsis tej zaum yuav convex, concave, los yog ca. Khawm me ntsis yog tag nrho puag ncig me ntsis haum rau feem ntau cov pob zeb nyuaj, sab saum toj rauj drilling daim ntaub ntawv.

Hla cov khoom thiab chisel khoomyog tsau-lub taub hau me ntsis uas muaj hardened hlau los yog carbide hniav. Chisel me ntsis yog txhais los ntawm ib tug hniav thaum hla cov khoom muaj ob los yog ntau dua cov hniav uas hla ntawm qhov chaw ntawm lub ntsis. Cov hniav feem ntau yog tapered rau ntawm qhov chaw txiav.
