Dab tsi yog qhov Down The Hole Hammer Bit?
A Down The Hole (DTH) Hammer Bit yog cov cuab yeej drilling siv hauv kev tsuas, kev tsim kho, thiab kev tshawb nrhiav kev ua ub no los tsim cov qhov hauv pob zeb lossis lwm yam ntaub ntawv nyuaj. DTH rauj me ntsis yog ib qho tseem ceeb ntawm DTH drilling system.
Dab tsi yog qhov zoo ntawm kev siv Down The Hole rauj me ntsis?
Siv lub Down Qhov (DTH) Rauj ntsis hauv kev ua haujlwm drilling muaj ntau yam zoo:
Faster Penetration Rates: DTH drilling feem ntau muab kev nkag mus sai dua nrog nce ntawm 20% ~ 30% piv rau lwm txoj kev drilling. Lub hammering nkaus ntawm DTH rauj ua ke nrog lub rotating laum me ntsis tso cai rau kom muaj txiaj ntsig thiab nrawm nrawm los ntawm cov pob zeb nyuaj.
Qhov zoo dua qhov ncaj: DTH drilling nyiam tsim cov qhov ncaj, uas yog qhov tseem ceeb hauv ntau daim ntawv thov. Qhov ncaj ntawm lub qhov, qhov tseeb dua qhov kev tso ntawm cov khoom tawg hauv cov mining lossis kev teeb tsa ntawm cov casings hauv geotechnical drilling.
Lub neej ntev ntev: LEANOMS DTH rauj cov khoom tsim los tiv thaiv kev cuam tshuam loj thiab puas cuam tshuam nrog kev drilling los ntawm cov ntaub ntawv nyuaj. Lub neej ntev yog li 3 mus rau 5 npaug ntawm cov phooj ywg kev lag luam. Qhov no durability ua rau lub neej ntev me ntsis, txo qhov zaus ntawm kev hloov me ntsis thiab ua kom tag nrho cov drilling efficiency.
Versatility: LEANOMS DTH drilling yog ntau yam thiab tuaj yeem siv rau hauv ntau daim ntawv thov, suav nrog kev tsuas, quarrying, dej zoo drilling, geothermal drilling, thiab kev tsim kho. Ntau hom DTH rauj cov khoom muaj kom haum rau cov kev xav tau tshwj xeeb drilling thiab geological tej yam kev mob.
Txo Qhov Deviation: DTH drilling feem ntau muaj kev sib txawv me ntsis los yog deflection los ntawm txoj kev npaj drilling. Tus nqi sib txawv tuaj yeem tswj tau li ntawm 5%. Qhov no yog qhov tseem ceeb rau kev tswj xyuas qhov tseeb ntawm qhov borehole, tshwj xeeb tshaj yog nyob rau hauv cov ntawv thov uas qhov kev tso tawm qhov tseeb yog qhov tseem ceeb.
Siv tau zoo hauv Hard Rock: DTH drilling yog tshwj xeeb tshaj yog siv rau hauv cov pob zeb nyuaj uas cov txheej txheem drilling tej zaum yuav tsawg dua. Kev sib xyaw ntawm percussion thiab kev sib hloov pab ua kom tawg thiab tshem tawm pob zeb zoo dua.
Kev Tiv Thaiv Cov Plua Plav Zoo: Kev siv cov cua compressed hauv DTH drilling pab kom tshem tawm cov pob zeb txiav los ntawm qhov borehole, txo qhov kev pheej hmoo ntawm me ntsis khi thiab txhim kho tag nrho cov drilling efficiency. Qhov no kuj pab tiv thaiv plua plav ntawm qhov chaw drilling.
Haum rau Ntau Qhov Qhov Loj: LEANOMS DTH cov cuab yeej drilling tuaj yeem ua kom haum rau ntau qhov ntawm lub qhov taub, ua rau nws hloov mus rau qhov kev xav tau sib txawv.
Yuav ua li cas xaiv ib tug Down The Hole rauj me ntsis raws li qhov xwm ntawm kev ua hauj lwm?
Axial siab, rotational ceev, cuam tshuam lub zog, thiab feem ntau zaus yog cov thawj yam uas cuam tshuam rau Down The Hole rauj ntsis qhov drilling ceev. Qhov kev xaiv ntawm cov tsis sib txawv heev rau cov pob zeb sib txawv hardness. Thaum drilling mus rau hauv lub pob zeb uas tsis tshua muaj hardness, Down The Hole rauj ntsis qhov drilling tsis yuav tsum tau raws li qhov xav tau ntawm teb crushing thiab txiav; Thaum drilling mus rau hauv lub pob zeb uas nyuaj tab sis tsis zoo cemented, qhov drilling tsis yuav tsum txaus siab rau qhov kev xav tau ntawm kev cuam tshuam crushing los tsim ntim crushing; thiab thaum drilling mus rau hauv lub pob zeb uas nyuaj thiab ntom, qhov drilling tsis yuav tsum tau raws li qhov xav tau ntawm ob qho tib si cuam tshuam thiab rotational pob zeb crushing.
Nrog rau ntau tshaj 20 xyoo ntawm kev paub hauv Drilling Industry, peb yog cov kws tshaj lij hauv cov pob zeb nyuaj drilling. Xaiv qhov zoo drilling cuab yeej yog qhov tseem ceeb rau koj cov khoom tsim tau thiab cov nqi khiav lag luam, thiab peb paub nws. Txhua LEANOMS DTH hammers thiab cov khoom yog tsim kom kawg thiab tsim kom muaj tus qauv tshwj xeeb. Peb cov DTH hammers thiab cov khoom muab kev ua tau zoo thiab kev tsim tau zoo uas xav tau los ntawm cov tshuab tho thoob ntiaj teb.
