Kev vam meej hauv kev lag luam xws li mining, tsev, thiab kev tshawb nrhiav roj thiab roj yog nyob ntawm qhov tseeb thiab muaj txiaj ntsig drilling cov txheej txheem. CovDHD raujyog ib qho yooj yim tshaj plaws thiab feem ntau siv cov cuab yeej muaj nyob rau hauv qhov kev lag luam no. Leveraging compressed cua kom muaj zog cuam tshuam rau ib tug xyaum me ntsis, no sophisticated down-the-qhov rauj (DTH rauj) yog ib tug percussive drilling tshuab uas tso cai rau ceev thiab zoo drilling los ntawm txawv pob zeb cov ntaub ntawv.
DHD rauj ua haujlwm li cas
DHD rauj kev ua haujlwm feem ntau yog siv los ntawm kev siv cua compressed, uas yog tsav mus rau hauv rauj ntawm txoj hlua xyaum. Cua siab nyob rau hauv lub rauj yog hloov mus rau ib theem zuj zus ntawm ceev, muaj zog blows aimed ntawm xyaum me ntsis. Qhov kev cuam tshuam rov ua dua no ua rau lub pob zeb ua rau lub borehole. Kev xa hluav taws xob zoo heev los ntawm DHD rauj ua rau nws muaj txiaj ntsig zoo rau kev drilling nyob rau hauv cov xwm txheej nyuaj.
Qhov raug zoo heev thiab kev vibration me ntsis ntawm DHD rauj ua kom muaj kev ua haujlwm zoo dua thiab txo qis hnav thiab tsim kua muag ntawm cov khoom siv drilling. Nws cov percussion ceev ua rau nws muaj peev xwm dhau lub pob zeb nyuaj formations sai dua li cov pa drilling cov txheej txheem, yog li ua rau kev khiav hauj lwm efficiency thiab txo cov nqi.
Tsim thiab siv: Versatility
ntau yam kev xav tau drilling hu rau ntau qhov loj thiab teeb tsa DHD rauj. Feem ntau, qhov loj ntawm lub rauj dictates txoj kab uas hla ntawm lub qhov DHD rauj tuaj yeem laum; tab sis, tus qauv tsim ntawm qee yam DHD rauj qauv yuav txawv raws li hom pob zeb lossis qhov drilling ib puag ncig. Nov yog qee qhov ntev thiab layouts:
Cov ntawv thov xav tau cov borehole me me, nrog rau cov uas muaj cov dej zoo drilling lossis cov phiaj xwm hauv tsev, yuav pom qhov me me rauj zoo meej.
Ib qho kev xaiv nruab nrab haum rau cov haujlwm nruab nrab, xws li engineering lossis kev tsim kho vaj tse,DHD340 rauj.
Tsim los rau kev ua haujlwm hnyav uas xav tau kev sib sib zog nqus lossis loj-ntev drilling-zoo li cov hauv mining lossis kev tshawb nrhiav roj tob-cov hammers loj no suav nrog DHD350, DHD360, thiab DHD380.
Tsis tas li ntawd, DHD hammers tuaj yeem sib txawv hauv lawv lub tshuab xa hluav taws xob, uas tseem ceeb heev rau lawv txoj haujlwm:
Tshwj xeeb tshaj yog nyob rau hauv kev xav tau drilling, hammers nrog footvalves muaj ib qho yooj yim tsim yam tsis muaj lub valve sab hauv, uas ua rau lawv muaj kev cia siab thiab kev saib xyuas yooj yim.
Muaj cov txheej txheem sab hauv, cov hammers tsis muaj footvalves muab kev ua tau zoo dua thiab ua kom zoo dua ntawm cov khoom siv laum.
Drill ntsis configurations
Tus tsim ntawm qhov xyaum me ntsis DHD rauj siv txiav txim siab nws cov txiaj ntsig ntxiv rau rauj nws tus kheej. Txhawm rau lav qhov ua tau zoo tshaj plaws, ntau hom pob zeb hu rau qhov sib txawv xyaum me ntsis teeb tsa:
Tsim nyog rau ntau hom pob zeb formations, qhov kev tsim no zoo tshaj plaws nyob rau hauv nruab nrab-nyuaj thiab homogeneous pob zeb. Nws txo qhov sib txawv ntawm qhov borehole thiab txhim kho slag tshem tawm, yog li ua tau zoo dua thiab zoo drilling.
Zoo meej rau drilling los ntawm cov pob zeb nyuaj heev los yog tsis tshua muaj corrosive, tshwj xeeb tshaj yog nyob rau hauv huab cua siab, yog lub ntsej muag tiaj tus tsim. Kev nrawm nrawm dua los ntawm kev tsim qauv no pab txo qis rauj lub cev hnav.
Shanks thiab laum me ntsis nyees khawm
Tsis tas li ntawd cuam tshuam rau kev ua haujlwm drilling yog hom shank siv thiab tsim cov nyees khawm carbide ntawm lub laum me ntsis:
Tsim los rau kev drilling ceev hauv cov pob zeb tawv thiab abrasive, cov nyees khawm ballistic Lawv qhov kev nkag tau zoo heev ua rau lawv zoo meej rau cov xwm txheej uas qhov kev ncua sij hawm yog thawj qhov tseem ceeb.
Zoo meej rau cov pob zeb nyuaj heev, cov nyees khawm kheej kheej muab cov kav ntev thiab nkag mus.
Hais txog qhov tsim ntawm me ntsis shank, ntau yam haum rau qhov sib txawv ntawm qhov drilling thiab rigs:
Feem ntau siv shanks, DHD Standard Shank haum rau ntau yam kev xyaum rigs thiab kev ua haujlwm.
Tsim luv luv thiab sib dua, SD Shank yog haum rau drilling hauv qhov chaw kaw.
Tsim los rau qee qhov rigs, lub shank no lav qhov kev sib txuas zoo ib yam thiab kev siv hluav taws xob zoo, yog li txhim kho kev ua tau zoo.
Cov txiaj ntsig ntawm DHD Rauj
Ntau qhov kev ua haujlwm drilling siv DHD rauj vim nws cov txiaj ntsig ntau yam:
Tshwj xeeb tshaj yog nyob rau hauv nyuaj thiab nyuaj pob zeb formations, DHD rauj txoj kev sib cuag rov ua kom ceev drilling.
Lub DHD rauj txo qis lub sijhawm ua haujlwm dav dav thiab cov nqi khiav lag luam los ntawm kev tso cai rau ib tus tho kom nrawm dua thiab zoo dua.
Txawm hais tias koj qhov drilling rau kev tshawb nrhiav roj, mining, lossis dej qhov dej, DHD rauj los ntawm ntau qhov ntau thiab tsawg kom haum rau koj qhov kev thov tshwj xeeb.
Tsim los tiv thaiv qhov xav tau ib puag ncig, DHD hammers muaj npe nrov rau lawv qhov kev ua haujlwm ntev, yog li txo cov khoom siv tsis ua haujlwm cuam tshuam txog kev poob qis.
DHD Rauj: kev txhim kho hauv kev ua haujlwm drilling
Txhawm rau ua kom tiav, DHD rauj yog cov cuab yeej muaj zog thiab siv tau zoo siv hauv ntau qhov haujlwm ntawm kev ua haujlwm drilling. Nws siv cov txheej txheem percussion-raws li drilling cov tswv yim thiab cov cua compressed cia nws sai heev txawm tias cov pob zeb nyuaj tshaj plaws. Txawm hais tias koj qhov project drilling yog qhov dej me me lossis qhov loj me me thiab kev tsim kho, DHD rauj qhov kev hloov pauv, kev cia siab, thiab kev lag luam ntawm tus nqi ua rau nws yog ib qho tseem ceeb hauv kev lag luam drilling. Qhov kev ua tau zoo ntawm koj txoj haujlwm yuav zoo dua los ntawm kev nqis peev hauv DHD rauj qhov tseeb thiabxyaum me ntsiskev sib txuas ua ke, yog li lav tias koj ua tiav cov haujlwm raws sijhawm thiab nyob rau hauv pob nyiaj siv.
Kev nkag siab txog ntau txoj kab uas hla, kev tsim, thiab kev teeb tsa ntawm DHD hammers nrog rau qhov xav tau ntawm kev xaiv qhov kev xyaum tsim nyog rau kev ua haujlwm pab cov neeg ua haujlwm nce drilling efficiency thiab lav qhov ua tau zoo tshaj plaws.
