Xaiv txoj caiDTH rauj (down-tus-Qhov rauj)Nws yog ib qho tseem ceeb rau kev ua tiav kev nkag mus sai dua, cov cuab yeej siv tau ntev dua, thiab cov nqi ua haujlwm qis dua. Nrog rau qhov sib txawv geological tej yam kev mob, qhov ntau thiab tsawg, thiab huab cua pressures, xaiv qhov raug rauj tuaj yeem cuam tshuam qhov drilling efficiency thiab tag nrho cov haujlwm ua haujlwm.
Hauv qab no yog ib daim ntawv qhia ua tiav, siv tau los pab koj xaiv qhov zoo tshaj plaws rauj rau koj daim ntawv thov drilling -txawm yog rau qhov dej, mining, quarrying, geothermal qhov dej, lossis kev tsim kho hauv paus.
Kawm paub ntau ntxiv txog DTH Hammer Technology
Txhawm rau pab cov neeg yuav khoom thiab cov kws tsim khoom kom nkag siab tob rau lawv txoj kev nkag siab, ntawm no yog cov kev nyeem ntawv tseem ceeb ntsig txog nruab nrab -siab rauj:

Teb-cov kauj ruam ua pov thawj los txuas ntxiv lub neej kev pabcuam thiab txo tus nqi drilling.
1. Txheeb xyuas koj qhov kev tsim Hardness
Pob zeb hardness yog qhovthawj thiab tseem ceeb tshaj plawsthaum xaiv DTH rauj.
Mos mus rau Nruab Nrab Pob Zeb (Tsawg dua los yog sib npaug rau 100 MPa) → Tsawg-Nias DTH rauj
Qhov zoo tshaj plaws rau:
Dej zoo drilling
Av, av nplaum, weathered pob zeb
Kev tsim kho ntiav ntiav drilling
Nruab nrab rau Hard Pob Zeb (80–180 MPa) → Nruab nrab -Nias DTH rauj
Cov nqi sib npaug thiab kev ua haujlwm, zoo tagnrho rau:
Geothermal drilling
Kev tsim kho & foundation drilling
Qhib me me- qhov mining
Nyuaj rau Ultra-Hard Pob Zeb (Ntau dua lossis sib npaug ntawm 150 MPa) → Siab- Siab DTH Rauj
Muab qhov cuam tshuam rau lub zog siab tshaj plaws thiab kev nkag mus nrawm tshaj plaws.
Haum rau:
Granite, basalt, tawv limestone
Mining & chaw txua txiag zeb blasting
Qhov tob tob drilling
Txhua rauj sib raug rau ib qho tshwj xeebme ntsis txoj kab uas hla.
| Rauj Qeb | Hom me me | Daim ntawv thov |
|---|---|---|
| Tsawg-siab | 65-120 hli | Dej qhov dej, pob zeb mos |
| Nruab nrab -siab | 90-150 hli | Kev tsim kho, Geothermal |
| Siab -siab | 110–254 mm | Mining, pob zeb nyuaj |
Yog tias koj twb paub koj lub qhov taub, xaiv rauj series uas npog qhov me me.
3. Sib tw rauj cua siab thiab cua siv
Kojcua compressoryuav tsum ua kom haum rau rauj cov kev xav tau. Txwv tsis pub, nkag mus yuav poob los ntawm 30-70%.
Piv txwv (High Pressure Series):
DHD350 →9-15 m³ / min
DHD360 →20-28 m³ / min
DHD380 →26-34 m³ / min
Yog tias koj lub compressor tsis tuaj yeem muab ntim txaus, txav mus rau qis dua - rauj siab.
Feem ntau DTH rauj ua haujlwm zoo tshaj plaws ntawm20-60 rpm.
Koj lub rig yuav tsum muab:
Txaus rotation torque
Txoj hlua xov zoo (API REG lossis DHD / CIR / thiab lwm yam)
Qhov hnyav txaus- ntawm- ntsis (WOB)
Yog tias kev sib hloov ceev dhau, kev sib txawv tshwm sim; qeeb dhau, nkag mus poob.
Rauj kev ua tau zoo yog hnyav heev los ntawm nws hom shank.
Common shanks:
DHD Series→ hnyav-duty, mining-qib
CIR Series→ pob nyiaj- tus phooj ywg, qis / nruab nrab siab
QL/SD/BR→ ntau yam qauv hauv cheeb tsam
Txoj cai ntawm tus ntiv tes xoo:
Match rauj → match me ntsis shank → match project yuav tsum.
Siab - cov hammers raug nqi ntau dua tab sis xyaum nrawm dua hauv cov pob zeb nyuaj.
Tsawg- cov rauj siab yog pheej yig dua thiab zoo tagnrho rau qhov ntiav / lub teeb drilling.
Txhawm rau kom tus nqi -ib -meter qis:
Siv lub siab kom raug
Siv kom raug lubrication
Xaiv qib siab - cov khoom zoo nrog cov carbide hwm
Ib tug zoo rauj muab:
ruaj khov piston tsim
Kev ua tau zoo huab cua
Premium alloy hlau
Ntev txhais tau tias- sij hawm- nruab nrab ntawm - tsis ua hauj lwm (MTBF)
Yooj yim tu qauv
Dminingwell hammers yog engineered rau:
Hard pob zeb cuam tshuam optimization
Kev txuag roj
Muaj zog qaug zog
Ntev kev pab cuam lub neej nyob rau hauv mining ib puag ncig
8. Cov ntsiab lus: Cov lus xaiv ceev
| Qhov xwm txheej | Pom zoo rauj |
|---|---|
| Mos / Nruab nrab av & pob zeb | Tsawg-siab |
| Mixed formations | Nruab nrab -siab |
| Hard granite / mining | Siab -siab |
| Qhov loj 65-120 mm | Tsawg-siab |
| Qhov loj 90-150 mm | Nruab nrab -siab |
| Qhov loj 110-254 mm | Siab -siab |
Xaus
Xaiv txoj cai DTH rauj kom ntseeg tauKev nkag siab ntau dua, lub neej siv tau ntev dua, thiab cov nqi khiav lag luam qis dua.
Txawm hais tias koj tab tom drilling qhov dej, mines, quarries, los yog lub hauv paus, xaiv qhov raug qib siab, qhov loj me, thiab compressor match yuav ua rau kev ua tau zoo.
