Ntau hom Drilling Bits

Drilling ntsis yog ib qho tseem ceeb tshaj plaws rau kev ua haujlwm zoo drilling. Yog li ntawd, xaiv qhov zoo laum khoom yog qhov tseem ceeb heev. Lub laum me ntsis rau roj thiab roj drilling muaj xws li dov cutter khoom thiab cov khoom ruaj khov.

Rolling Cutter Khoom

Rolling cutter khoom tseem hu ua roller cone khoom lossis tri-cone khoom. Rolling cutter khoom muaj peb lub cones. Txhua lub khob hliav qab tuaj yeem tig ib tus zuj zus thaum lub laum txoj hlua tig lub cev ntawm me ntsis. Lub cones muaj cov menyuam bearings haum thaum lub sijhawm sib dhos. Cov dov txiav cov khoom tuaj yeem siv los laum ib qho kev tsim yog tias xaiv qhov zoo cutter, bearing, thiab nozzle.

Muaj ob hom dov cutter khoom uas yog milled-tooth bits thiab tungsten carbide inserts (TCI khoom). Cov khoom no raug cais los ntawm kev tsim cov hniav li cas:

Milled-tooth khoom

Milled-tooth bits muaj steel hniav cutters, uas yog fabricated raws li ib feem ntawm me ntsis cone. Cov khoom txiav los yog gouge formations tawm thaum lawv tig. Cov hniav sib txawv ntawm qhov loj thiab cov duab, nyob ntawm qhov tsim. Cov hniav ntawm cov khoom sib txawv nyob ntawm kev tsim raws li hauv qab no:

Mos tsim: Cov hniav yuav tsum tau ntev, slender, thiab dav spaced. Cov hniav no yuav tsim cov cuttings tshiab los ntawm cov mos mos.

Tungsten Carbide Insert (TCI) los yog Ntxig cov khoom feem ntau muaj tungsten carbide inserts (cov hniav) uas nias rau hauv lub khob me ntsis. Cov inserts muaj ob peb daim duab xws li ntev-extension shapes, round-shaped inserts, thiab lwm yam.

Cov hniav ntawm cov khoom sib txawv nyob ntawm qhov tsim raws li hauv qab no:

Mos tsim: Ntev-extension, chisel-puab inserts

Hard tsim: luv-extension, rounded inserts

Tsau Cutter khoom

Tsau cutter khoom muaj xws li lub cev me ntsis thiab cov khoom txiav ua ke nrog lub cev me ntsis. Cov khoom siv ruaj khov yog tsim los txhawm rau khawb qhov los ntawm kev sib tsoo ntau yam tsis yog chipping lossis gouging formations, xws li dov cutter khoom. Cov khoom no tsis muaj cov khoom txav xws li cov cones lossis bearings. Cov khoom ntawm cov khoom yog tsim los ntawm cov khoom me me uas tsim los ntawm cov hlau los yog tungsten carbide matrix thiab cov hniav ruaj khov ua ke nrog cov cutters-resistant. Cov cutters hauv cov khoom uas muaj nyob rau hauv kev ua lag luam yog Polycrystalline Pob Zeb Diamond Cutters (PDC) thiab ntuj los yog hluavtaws pob zeb diamond cutters.

Niaj hnub no, nrog rau kev txhim kho uas tau ua nyob rau hauv kev kho cov cuab yeej cuab tam, PDC cov khoom tuaj yeem xyaum yuav luag txhua hom kev tsim los ntawm cov khoom muag mus rau qhov nyuaj.

Polycrystalline pob zeb diamond compact (PDC) laum khoom yog tsim nrog hluavtaws pob zeb diamond cutters nyob rau hauv cov hlau los yog matrix lub cev khoom. PDC laum cov khoom tau hloov pauv kev lag luam drilling nrog ntau daim ntawv thov ntau thiab muaj peev xwm nkag siab (ROP) siab.

Yog tias koj txaus siab rau PDC cutter thiab xav tau cov ntaub ntawv ntau ntxiv thiab cov ntsiab lus, koj tuaj yeem tiv tauj peb hauv xov tooj lossis xa ntawv ntawm sab laug, lossis xa US MAIL rau hauv qab ntawm nplooj ntawv.
