Meta Description:Kawm paub tias DTH rauj yog dab tsi, nws ua haujlwm li cas, nws cov khoom, qhov zoo, kev siv, thiab yuav xaiv tus qauv zoo li cas. suav nrog kev txuas sab hauv mus rau qis -, nruab nrab -, thiab siab - siab DTH rauj rau txhua qhov kev drilling.
DTH Hammer yog dab tsi thiab nws ua haujlwm li cas?
A DTH rauj (down-tus-Qhov rauj)Nws yog ib qho cuab yeej siv rau kev siv hauv mining, quarrying, dej zoo drilling, foundation engineering, thiab tej yaam num geothermal. Nws ua haujlwm los ntawm kev tso lub rauj ncaj qha tom qab lub laum me ntsis, tso cai rau lub zog cuam tshuam kom xa ncaj qha mus rau hauv pob zeb nrog tsawg zog poob.
Qhov no technology muajceev nkag mus ceev, zoo heev straightness, thiab npaum drillingtxawm nyob rau hauv lub hardest formations. Niaj hnub nimno DTH rauj-xws li cov uas muaj los ntawmDminingwell-yog tsim los rau kev ua haujlwm siab thoob plaws - siab, nruab nrab - siab, thiab siab - siab.
DTH rauj ua haujlwm li cas?
Lub hauv paus ntsiab lus ua haujlwm ntawm DTH rauj tuaj yeem sau ua plaub kauj ruam:
1. Siab-Huab cua nkag rau rauj
Compressed cua ntws los ntawm cov yeeb nkab laum rau hauv rauj. Cov huab cua tsav lub piston sab hauv thiab ib txhij ntxuav cov txiav los ntawm lub qhov.
Yog tias koj xav nkag siab tias qib siab cuam tshuam li cas rau kev ua haujlwm drilling, sib piv
✔ Tsawg-siab rauj →
✔ Nruab nrab -siab rauj →
✔ Siab -siab rauj →
2. Piston Strikes the Drill Bit
Nyob rau hauv lub rauj zaum ib tug precisely machined piston. Nws nrawm nrawm nce thiab nqis, tsoo me ntsis shank kaum ob zaug ib ob.
Qhov kev cuam tshuam lub zog no ua rau lub pob zeb ncaj qha hauv qab me ntsis.
3.Kev sib hloov ntxiv txiav txiav
Thaum lub rauj muab kev cuam tshuam, lub laum rig muab kev sib hloov. Qhov kev sib xyaw no:
Tsim cov qhov sib npaug sib npaug
Txo kev sib txawv
Txhim khu kev nkag mus rau hauv cov pob zeb nyuaj
DTH rauj feem ntau ua haujlwm ntawm20-60 rpm, nyob ntawm tus qauv thiab tsim.
4. Cua ntws cov pob zeb txiav tawm ntawm lub qhov
Cov cua compressed tib yam uas tsav lub piston kuj ntws los ntawm lub ntsej muag me ntsis, nqa cov khoom tawg tawm ntawm qhov borehole.
Qhov no ua kom lub qhov huv si thiab ua kom ruaj khov drilling.
Cov Cheebtsam tseem ceeb ntawm DTH Rauj
Tus qauv DTH rauj muaj xws li:
Top Sub
Cua Distributor / Check Valve
Piston
Sab hauv lub tog raj kheej
Ntsis Retainer
Tsav Chuck
Hammer Bit (sib cais)
Txhua yam khoom yuav tsum raug tsim los ua kom tiav kev ua tau zoo thiab ua haujlwm ntev.
Daim ntawv thov ntawm DTH Hammers
DTH drilling yog dav siv hauv:
Mining & chaw txua txiag zeb blasting
Qhib - qhov drilling
Dej zoo drilling
Geothermal qhov dej
Foundation & piling
Tunneling & underground engineering
Roj & roj ua ntej -splitting
Kev tsim kho & infrastructure
Hom DTH Hammers (Kab Siab)
Qhov chaw sib txawv ntawm qhov sib txawv yuav tsum muaj cua sib txawv. Dminingwell faib nws cov hammers rau hauvlow-siab, nruab nrab-siab, thiab siab-siabpawg.
1. Tsawg-Nias DTH Rauj (1.0–1.4 MPa)
Tsim los rau kev tsim cov mos mos thiab nruab nrab, qhov dej zoo drilling, thiab cov nqi qis dua -.

2. Nruab nrab -Nias DTH Hammers (1.2–1.8 MPa)
Qhov zoo tshaj plaws sib npaug ntawm lub zog tso zis thiab tus nqi. Zoo tagnrho rau kev tsim kho, geothermal drilling, thiab dav - lub hom phiaj pob zeb drilling.
👉 Internal Link to Mid-Pressure Models (MW-M3 / MW-M3K / MW-M4):

Qhov zoo ntawm DTH Rauj Drilling
Muaj zog pob zeb nkag
Lub zog cuam tshuam raug xa ncaj qha los ntawm lub rauj mus rau qhov me ntsis - tsis muaj lub zog laum ntev.
Superior Qhov Ncaj Ncaj
Vim lub rauj nyob rau hauv qab ntawm lub qhov, nws stabilizes lub laum txoj hlua thiab ua rau lub borehole ntsug.
Kev tsim khoom siab
Piv nrog rau sab saum toj - rauj drilling, DTH drilling tuaj yeem nce mus txog50% sai duahauv nruab nrab - mus rau - pob zeb nyuaj.
Cov nqi khiav lag luam qis dua
Tsawg vibration txhais tau tias:
Cov cuab yeej siv tsawg dua
Ntev me ntsis lub neej
Txo lub sij hawm txij nkawm
Cov Tswv Yim Kho Kom Zoo Rau Lub Neej Ntev Rauj
✔ Lubricate O-rings txhua hnub
✔ Cia huab cua qhuav (tsis txhob muaj dej hauv rauj)
✔ Siv cov roj laum kom raug lossis pob zeb laum lubricant
✔ Tshawb xyuas me ntsis splines thiab chuck
✔ Hloov cov pistons lossis lub tog raj kheej hnav kom sai
