Tungsten carbide Nozzle rau PDC Laum Ntsis

    PDC laum khoom yog cov cuab yeej siv pob zeb tawg tau siv dav hauv cov roj thiab roj drilling, kev tshawb nrhiav geological, thiab lwm yam. Lub tungsten carbide nozzle yog ib qho ntawm nws cov khoom tseem ceeb. Feem ntau ntsia ntawm lub qhov dej ntawm PDC laum me ntsis, nws txhaj cov dej muaj zog drilling kom txias, ntxuav, thiab pab pob zeb tawg. Nws qhov kev ua tau zoo cuam tshuam ncaj qha rau kev xyaum tab sis nws yog

kev pab cuam lub neej thiab drilling efficiency.

I. Nozzle Connection Method:

    Nws yuav tsum phim lub qhov dej ntawm PDC laum ntsis. Ib qho kev sib txuas yog ib qho kev sib txuas (sab nraud lossis sab hauv, nrog 3A-qib precision rau

    xyuas kom tsis txhob xau nyob rau hauv siab). Qee qhov me me nozzles siv qhov cuam tshuam haum (nias-haum), uas tiv thaiv kev xoob tom qab kev teeb tsa.

II. Nozzle Cov yam ntxwv: Tungsten Carbide (WC)

    1. High Hardness thiab Wear Resistance: Tungsten carbide lub hardness yog thib ob tsuas yog pob zeb diamond, ua rau nws resistant rau yaig los ntawm abrasive hais nyob rau hauv lub drilling kua (xws li sandstone thiab hlau khib nyiab), ncua lub neej nozzle.

    2. Corrosion Resistance: Nws tiv taus corrosion los ntawm cov tshuaj additives hauv cov dej drilling (xws li ntsev thiab kua qaub).

    3. Impact Resistance: Tungsten carbide feem ntau siv cobalt (Co) ua

binder, muab ib qho degree ntawm toughness thiab tiv thaiv brittle puas.

III. Carbide Nozzle Cov qauv tsim qauv

    1. Streamlined Inner Bore: Txo turbulence thiab txhim kho cov kua dej. Cov hom muaj xws li:

    2. Ncaj Nraim: Yooj yim thiab ruaj khov, haum rau cov pa drilling.

    3. Venturi: Ib tug converging-diverging qauv nce tus nqi ntws thiab txhim khu kev tshem tawm nti.

    4. Ntau qhov ntau thiab tsawg: Lub nozzle puab txoj kab uas hla (feem ntau 6-16mm) yog xaiv raws li qhov drilling kua ntws tus nqi thiab yuav tsum tau txhaj tshaj tawm.

    Replaceable Design: Tsis tas yuav hloov tag nrho cov laum me ntsis tom qab hnav, txo cov nqi kho.

IV. Lub luag haujlwm tseem ceeb ntawm tungsten carbide nozzles yog raws li hauv qab no:

    1. Txias cov Cutters

Cov cutters ntawm PDC laum me ntsis tsim kom muaj qhov kub thiab txias thaum lawv tig ntawm kev kub ceev kom txiav pob zeb.  Kev kub ntau dhau tuaj yeem ua rau carbonization thiab tsis ua haujlwm ntawm cov pob zeb diamond txheej. Lub siab-siab drilling kua ejected los ntawm lub tungsten carbide nozzle ncaj qha tshem tawm cov cua sov no, ua kom lub cutter kub nyob rau hauv ib tug muaj kev nyab xeeb ntau yam (feem ntau hauv qab no 700 ° C) thiab tiv thaiv thermal puas.

    2. Ntxuav pob zeb txiav

Pob zeb cuttings generated thaum lub sij hawm txiav cov txheej txheem tuaj yeem sib sau nyob ib ncig ntawm lub cutters, ua rau "mav balling" (ib qho sib tov ntawm cuttings thiab drilling kua adhering rau lub laum me ntsis), txo cov pob zeb tawg efficiency. Lub dav hlau dej ceev ceev los ntawm lub nozzle tam sim ntawd disperses thiab displaces cov cuttings, tswj kev sib cuag zoo ntawm lub cutter thiab pob zeb.

    3. Hydraulically pab pob zeb tawg

Lub dav hlau los ntawm lub nozzle (ntawm speeds txog li 100-200 m / s) cuam tshuam lub pob zeb nto, tsim hydraulic tawg. Qhov no synergistic nyhuv, ua ke nrog cov neeg kho tshuab txiav kev txiav txim ntawm cutters, txo cov pob zeb tawg tsis kam, ho nce nkag mus ceev, tshwj xeeb tshaj yog nyob rau hauv nyuaj formations.

V. Cov ntawv thov

Carbide nozzles feem ntau yog siv hauv cov xwm txheej hauv qab no:

    1. Mos mus rau nruab nrab-tawv formations, xws li shale thiab limestone, qhov uas lawv ntxiv cov shearing npaum li cas ntawm PDC laum khoom.

    2. Cov qhov dej tob / kab rov tav yuav tsum muaj kev siv siab siab thiab kev tswj xyuas hydraulic, qhov kev ntseeg siab ntawm tungsten carbide nozzles yog qhov tseem ceeb.

    3. Cov kev ua kom zoo heev, xws li quartz sandstone, muaj kev hnav zoo dua piv rau cov qauv hlau alloy steel nozzles.
