DTH (Down-The-Hole) rauj yog cov cuab yeej siv hauv kev ua haujlwm drilling kom nkag mus rau cov pob zeb nyuaj. DTH Hammer Specifications tuaj yeem sib txawv raws li cov ntawv thov tshwj xeeb thiab cov kev xav tau. Txawm li cas los xij, ntawm no yog qee qhov tshwj xeeb thiab cov yam ntxwv cuam tshuam nrog DTH rauj:
Loj thiab Luj:
DTH hammers tuaj nyob rau hauv ntau qhov ntau thiab tsawg thiab qhov hnyav kom haum rau qhov sib txawv drilling rigs thiab kev siv. Qhov ntau thiab tsawg yog li ntawm 3 ntiv mus rau 24 ntiv hauv txoj kab uas hla.
Ua haujlwm siab:
DTH hammers ua haujlwm nyob rau hauv ib qho tshwj xeeb ntawm huab cua siab, feem ntau ntsuas hauv PSI (Pounds per Square Inch). Kev ua haujlwm siab tuaj yeem sib txawv raws li qhov loj me thiab qhov hardness ntawm cov pob zeb tsim.
Kev siv cua:
DTH hammers xav tau qee qhov ntim ntawm cov cua compressed kom ua haujlwm zoo. Kev noj huab cua feem ntau ntsuas hauv cubic feet ib feeb (CFM) lossis cubic meters ib feeb (CMM).
Impact zaus:
DTH hammers tsim cov kev cuam tshuam ntawm ib zaus, ntsuas hauv tshuab ib feeb (BPM). Kev cuam tshuam ntau dua yog feem ntau haum rau cov pob zeb nyuaj.
Bit Shank Hom:
DTH hammers yog tsim los kom haum me ntsis shank hom, xws li SD, DHD, COP, thiab QL ntawm lwm tus. Kev xaiv ntawm me ntsis shank nyob ntawm qhov drilling rig thiab daim ntawv thov npaj.
Rauj lub cev Khoom siv:
DTH hammers feem ntau yog ua los ntawm cov hlau zoo los yog cov ntaub ntawv alloy los tiv thaiv qhov cuam tshuam thiab puas thaum lub sijhawm drilling.
Seals thiab Bearings:
DTH hammers tau nruab nrog cov ntsaws ruaj ruaj thiab cov kabmob los tiv thaiv huab cua thiab dej nkag, ua kom muaj kev ua haujlwm zoo thiab ua kom lub rauj ntev ntev.
Bit Retention System:
DTH hammers siv ntau yam kev tuav tswj, xws li circlips, springs, lossis pins, kom ruaj ntseg rau hauv qhov chaw thaum ua haujlwm.
Sab hauv tsim:
Kev tsim sab hauv ntawm DTH rauj, suav nrog piston, valve, thiab airflow txoj hauv kev, yog qhov tseem ceeb rau kev ua kom lub zog hloov pauv thiab ua kom muaj txiaj ntsig zoo tshaj plaws.
Xov Connections:
DTH hammers muaj threaded kev sib txuas rau txuas mus rau lub laum yeeb nkab los yog laum pas nrig. Ntau hom xov muaj xws li API, BECO, thiab Remet, thiab lwm yam.
Rov qab Circulation (RC) Muaj peev xwm:
Qee qhov DTH hammers yog tsim los pab txhawb kev thim rov qab drilling, qhov twg cov dej drilling yog siv los nqa cov txiav los ntawm lub qhov borehole.
Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias qhov tshwj xeeb DTH rauj tshwj xeeb tuaj yeem sib txawv raws li cov chaw tsim khoom thiab cov qauv. Thaum xaiv DTH rauj, nws yog ib qho tseem ceeb uas yuav tsum sab laj nrog cov chaw tsim khoom cov lus qhia thiab cov lus pom zoo kom ntseeg tau tias muaj kev sib raug zoo nrog cov drilling rig thiab cov kev npaj drilling.
