- Khoom Taw qhia
Cov Qauv Siv Tau: MT/T 537-1996 Coal Drill Bits, siv tau rau kev ua haujlwm drilling hauv cov thee thiab coal-pob zeb formations.
Cov khoom siv sib txuam: ntub dej hollow spiral laum rods nrog lub hauv paus dej nkag, siv nrog pneumatic thee laum thiab hluav taws xob thee xyaum. Hom laum no feem ntau yog siv rau kev tshawb nrhiav roj, kev tshawb nrhiav dej, thiab kev ua haujlwm drilling hauv kev tsim kho pob zeb hauv av thiab tunneling.
Qauv thiab Txoj Cai Ua Haujlwm
Cov yam ntxwv tseem ceeb
Lub laum me ntsis yog tsim los nrog lub hauv paus dej nkag. Cov dej siab ntws los ntawm lub tshuab drilling los ntawm lub hollow ntub laum pas nrig thiab tawm los ntawm lub hauv paus qhov ntawm lub laum me ntsis mus rau hauv qab ntawm lub borehole.
Qhov no ntub dej drilling system pab:
Ncua plua plav thaum lub sijhawm drilling
Txias cov carbide txiav cov hniav
ntub thiab loosen thee cuttings
Txhim kho qhov kev tshem tawm ntawm cuttings los ntawm cov kauv flutes
Cov wetted cuttings yog tsis tu ncua thauj tawm ntawm lub borehole los ntawm cov kauv flutes, pab tswj kom zoo drilling thiab txo qhov kev pheej hmoo ntawm lub qhov blockage.
Drill Bit Lub Cev
Lub ntsis lub cev yog tsim los ntawm forged alloy steel. Cemented carbide txiav cov hniav yog brazed rau hauv lub taub hau me ntsis.
Cov qauv tsim feem ntau yog ob -tis (Y-hom) kev teeb tsa.
Ob hom tseem ceeb yog muaj:
Hom I: Rau qhov muag muag
Hom II: Rau cov thee tawv thiab thee- pob zeb tsim
Kev sib txuas
Lub laum me ntsis siv ib qho kev sib txuas hauv threaded. Cov xov xov zoo xws li M14 × 1.5 thiab M16 × 2.
Lub ntsis yog txuas ncaj qha mus rau ib tug ntub hollow spiral laum pas nrig los ntawm cov xov txuam.
Qhuav- hom laum cov khoom feem ntau siv lub qhov rooj plaub - nyob rau hauv kev sib txuas thiab tsis muaj dej nkag. ntub- hom thiab qhuav- hom tho khoom yuav tsum tsis txhob hloov pauv.

Qhov zoo
1. Kev tiv thaiv plua plav ntub dej zoo
Cov dej muaj zog txhawb nqa cov hmoov av uas tsim los thaum lub sij hawm drilling, pab ua kom tau raws li cov av hauv av mine plua plav- tswj thiab kev nyab xeeb. Cov me ntsis yog tshwj xeeb tshaj yog haum rau siab -gas mining ntsej muag uas yuav tsum tau siv cov plua plav tawm.
2. Carbide hniav txias thiab tiv thaiv
Kev khiav dej txias ua rau cov cemented carbide txiav cov hniav, txo cov cua sov thiab thermal puas thiab pab txuas ntxiv me ntsis kev pab cuam lub neej.
3. Txhim kho Cuttings tshem tawm
Dej ntub cov thee cuttings thaum lub spiral flutes tsis tu ncua thauj cov cuttings tawm ntawm lub borehole. Qhov no yuav pab txo qis kev pheej hmoo ntawm me ntsis jamming thiab borehole blockage thiab txhim kho kev ua haujlwm ntawm drilling.
4. Kev sib txuas ceev ceev
Kev sib txuas threaded tso cai rau kev sib dhos ceev thiab disassembly. Alignment ntawm lub laum me ntsis thiab laum pas nrig yog yooj yim thiab yooj yim.
Kev txwv
1. Yuav tsum muaj lub pas dej ntub dej Drill
Lub ntsis yuav tsum tau siv nrog ib tug hollow laum pas nrig nruab nrog ib tug dej nkag. Nws tsis tuaj yeem txuas nrog cov khoom qhuav- hom xyaum qws.
2. Yuav tsum muaj dej txaus
Kev siv dej yuav tsum ua kom tau raws li qhov xav tau. Cov dej tsis txaus tuaj yeem txo cov kev ua haujlwm ntawm cov plua plav tawm thiab carbide hniav txias.
3. Tsis pom zoo rau kev tsim tsis ruaj tsis khov
Nyob rau hauv cov formations prone rau borehole vau, dej txhaj yuav ua rau kom muaj kev pheej hmoo ntawm borehole phab ntsa instability.
4. Tsis haum rau dej ua kom tiav -Kev ua haujlwm hauv av dawb
Cov ntub dej - hom laum me me yuav tsum muaj cov dej tsis tu ncua thiab yog li tsis tsim nyog rau cov dej drilling uas tsis tuaj yeem muab tau.

Kev Tiv Thaiv Kev Ua Haujlwm
Txheeb xyuas qhov dej ntws ua ntej Drilling
Nco ntsoov xyuas tias cov dej hla dhau ntawm lub pas nrig thiab lub laum me ntsis yog qhov tseeb thiab tsis muaj kev cuam tshuam. Kev pom zoo dej siab yog 0.3-0.8 MPa.
Tsis txhob txuas lub ntub me ntsis rau ib qho khoom Dry Drill Rod
Ib qho ntub dej - hom laum me me yuav tsum tsis txhob txuas nrog lub laum khoom. Yog tias tsis muaj dej nkag, dej tsis tuaj yeem ncav cuag qhov me me thiab cov dej ntub dej yuav ploj mus.
Hloov cov hniav puas Carbide sai sai
Yog hais tias cov cemented carbide cov hniav ua xoob, chipped, tawg, los yog lwm yam puas, hloov lub laum me ntsis tam sim ntawd. Tsis txhob txuas ntxiv drilling nyob rau hauv lub zog ntau dhau nrog ib qho kev puas tsuaj me ntsis.
Tswj Kev Siv Dej tsis tu ncua thaum lub sijhawm Drilling
Kev xa dej yuav tsum tau tswj xyuas thoob plaws hauv kev ua haujlwm drilling. Tsis txhob txuas ntxiv drilling tom qab tso tseg cov dej, vim tias qhov txias tsis txaus tuaj yeem ua rau cov hniav carbide overheat thiab raug kev puas tsuaj rau thermal.
Siv tau Formations
Cov ntub dej - hom twist thee me ntsis yog tsim rau cov thee thiab thee- pob zeb tsim nrog lub zog uniaxial compressive (UCS) tsawg dua lossis sib npaug li 50 MPa.
Nws tsis pom zoo rau kev tsim cov pob zeb nyuaj. Rau cov ntawv thov nyuaj- pob zeb drilling, ib qho kev xyaum pob zeb tsim nyog yuav tsum raug xaiv raws li cov qauv tsim thiab cov qauv siv mining.
