Rotary drilling rigs muaj ntau yam kev xyaum, nrog cov qauv sib txawv, hom, thiab qhov ntau thiab tsawg kom haum rau ntau qhov chaw geological thiab kev tsim kho. Hauv qab no yog ib daim ntawv teev cov kev ua tau zoo thiab cov yam ntxwv ntawm cov khoom siv tho.#drill qhov#
I. Hydraulic Grab Bucket: Nrog rau kev nce ntxiv ntawm cov phab ntsa txuas ntxiv thiab tiv thaiv -seepage phab ntsa tsim cov phiaj xwm, rotary drilling rigs tuaj yeem hloov kho yooj yim rau kev ua haujlwm. Lub thoob khib nyiab hydraulic yog hydraulically tsav, yuav tsum tsuas yog ib lub tog raj kheej hydraulic, ob lub qhov hluav taws xob / qhov hluav taws xob cov kav dej, thiab ib lub valve tswj.
II. Rotary Drilling Buckets: Raws li tus naj npawb ntawm cov hniav ntsia, lawv tuaj yeem muab faib ua cov thoob cov hniav thiab cov thoob cov hniav; Raws li tus naj npawb ntawm cov phaj hauv qab, lawv tuaj yeem muab faib ua ob - thoob hauv qab thiab ib qho - thoob hauv qab; raws li tus naj npawb ntawm qhov qhib, lawv tuaj yeem muab faib ua ob - qhov rooj thoob thiab ib qho - qhov rooj thoob; Raws li lub taper ntawm lub thoob, lawv muaj peev xwm muab faib ua conical thoob thoob thiab ncaj thoob thoob; Raws li cov duab hauv qab phaj, lawv tuaj yeem muab faib ua lub lauj kaub - hauv qab thoob thiab tiaj tus - hauv qab thoob. Kev sib xyaw ua ke ntawm cov qauv no, nrog rau kev hloov pauv ntawm qhov muaj lossis tsis muaj qhov vents thiab qhib cov txheej txheem, muaj ntau ntau hom kev sib hloov lub thoob tuaj yeem tsim. Feem ntau, ob lub - thoob hauv qab yog tsim rau ntau yam ntawm geological formations, thaum ib zaug - thoob hauv qab tsuas yog haum rau cov av cohesive heev. Muab ob npaug rau- lub thoob qhov rooj yog tsim rau ntau qhov kev tsim ntawm geological, thaum ib zaug - qhov rooj thoob tsuas yog siv rau loj - kab pebbles thiab av nplaum tawv.#drill qhov #
III. Kauv Drill Bits: Conical laum cov khoom nrog ob kawg thiab ob npaug rau cov ntsia hlau yog tsim rau cov tawv tawv. Muab ob npaug rau-kawg ib leeg ntsia hlau laum khoom yog tsim rau huab cua puag, pebbles, thiab permafrost. Cov laum khoom no, nruab nrog ntau yam kev txiav cov hniav, tuaj yeem muab tau ntxiv rau hauv ntau hom kev xyaum siv los ntawm kev hloov pauv hauv cov hniav, suab, thiab lub kaum sab xis. Ncaj auger laum khoom muab faib ua ob hom: thoob- hniav ncaj auger thiab cutter- hniav ncaj auger (ob npaug- xaus, ob - xaus), haum rau cov av xuab zeb thiab tsis zoo cemented me me - txoj kab uas hla gravel txheej; ob npaug - xaus ib qho auger, haum rau cov av xuab zeb thiab cov av txheej; thiab ib zaug - xaus ib qho auger, haum rau cov cemented tsis zoo loj - kab pebbles, cohesive av, thiab av nplaum tawv. Ob npaug- xaus, triple- xaus, thiab plaub fab- xaus augers kuj muaj, haum rau cov pob zeb nyuaj lossis pob zeb.#drill qhov#
IV. Enlarged Base Drill Bits: Txhawm rau kom cov kabmob muaj peev xwm ntawm ib pawg uas tsis muaj qhov loj ntawm pawg lossis qhov tob, cov chaw tsim khoom feem ntau siv cov pawg loj loj. Loj lub hauv paus drilling ntawm rotary drilling rigs yuav tsum tsis muaj kev hloov kho; tsuas yog ib lub hauv paus loj laum me ntsis yuav tsum tau xaiv. Mechanical enlarged base laum khoom feem ntau yog siv. Cov khoom no kuj yooj yim rau siv thiab tswj. Lawv muaj nyob rau hauv sab saum toj - qhib thiab hauv qab - qhib hom, nrog plaub- txuas qhib mechanism, thiab siv rau hauv cov av txheej, cua daj cua dub, huab cua nruab nrab, thiab txawm tias nyuaj bedrock. Txij li thaum teb drilling tsis yog - ncig, tom qab lub hauv paus loj drilling, slag tuaj yeem raug tshem tawm siv lub thoob tshem tawm slag.
V. Percussion Drill Bits thiab Impact Drill Bits: Percussion laum khoom thiab percussion laum khoom yog tshwj xeeb tshaj yog zoo thaum drilling loj - kab pebbles, pob zeb loj, thiab nyuaj bedrock ua ke nrog rotary drilling. Cov khoom no yog siv los ntawm kev ncua lub laum me ntsis ntawm lub teb drilling rig's auxiliary nuv. Txhawm rau kom tau txais txiaj ntsig zoo, lub koom haum sib txuas yuav tsum muaj txoj hlua pub dawb tso tawm kom muaj kev cuam tshuam txaus.
VI. Core Sampling Bits: Tam sim no, muaj ob hom: toothed core laum khoom, haum rau nruab nrab - tawv bedrock thiab gravel, thiab roller cone core laum khoom, haum rau cov pob zeb loj thiab pob zeb loj. Nyob rau hauv ob hom tseem ceeb no, cov tub ntxhais laum cov khoom tau muab faib ntxiv rau cov neeg uas muaj thiab tsis muaj cov cuab yeej ua piv txwv, nyob ntawm qhov nyuaj ntawm cov tub ntxhais sampling. Vim hais tias cov menyuam lub khob hliav qab core laum cov khoom siv feem ntau yog siv rau cov pob zeb nyuaj drilling thiab rau qhov drilling loj annular thaj chaw, rotary drilling rigs, yog tias nruab nrog cov peev txheej tsim nyog, kuj tseem tuaj yeem sib xyaw rov qab rov qab drilling rau hauv qhov laum me ntsis txhawm rau txhim kho kev ua haujlwm drilling.#drill qhov #
