Yog tias koj tab tom nrhiav cov pob zeb tho pob zeb rau cov neeg siv khoom hauv mining, quarrying, lossis tunnel tsim, koj yuav tau khiav mus rau tib lo lus nug los ntawm cov neeg yuav khoom:"Kuv puas yuav tsum tau txiav cov chisel khoom lossis khawm khoom?"
Cov lus teb instinctive yog khawm me ntsis - lub neej ua haujlwm ntev dua, nkag mus sai dua, thiab cov ntaub ntawv ua haujlwm zoo dua ntawm daim ntawv. Tab sis cov lus teb ntawd tsis yog rau ib feem tseem ceeb ntawm cov ntawv me me - qhov drilling. Pom zoo cov khoom "zoo dua" rau tus neeg yuav khoom uas tsis xav tau nws tsis tsim kev ntseeg siab. Nws tsim rov qab, tsis txaus siab, thiab poob nyiaj.
Nov yog yuav ua li cas los ntawm kev txiav txim kom raug.
Qhov ob hom me ntsis ua tau txawv
A tapered chisel xyaum me ntsismuaj ib lub tiaj tiaj tungsten carbide hniav brazed hla lub ntsej muag me ntsis. Thaum lub pob zeb laum xa ib qho kev cuam tshuam, cov hniav ntawd tsoo lub pob zeb hauv ib qho kev tawm suab, shearing thiab chipping khoom raws txoj kev ncaj. Tus tsim yog mechanically yooj yim, uas yog precisely nws lub zog.
A tapered khawm me ntsisHloov cov hniav ntawd nrog ntau lub tungsten carbide inserts - hemispherical lossis parabolic nyees khawm - faib thoob plaws lub ntsej muag. Txhua lub pob tseem ceeb cuam tshuam lub zog rau ntawm qhov chaw sib cuag me me, crushing pob zeb ntau dua li shearing. Cov ntsiab lus sib txuas ntau dua, kev sib tsoo ntau dua, kev ua haujlwm zoo ib yam hauv cov khoom siv nyuaj.
Ob hom siv ib qho kev sib txuas (7 degree, 11 degree, lossis 12℃taper) rau kev sib raug zoo nrog ib tug tapered laum pas nrig, thiab ob leeg yog tsav los ntawm lub teeb yuag pneumatic pob zeb xyaum xws li YT28 los yog Y24 - cov khoom txheem rau me me - txoj kab uas hla qhov drilling nyob rau hauv underground mining thiab quarry applications.
Qhov txawv tsis yog qhov twg ua tau zoo dua hauv kev sib cais. Qhov sib txawv yog qhov sib txawv ntawm cov xwm txheej tiag tiag uas koj cov neeg yuav khoom tau khawb hauv.
Qhov kev txiav txim siab tiag tiag los rau Pob Zeb Hardness
Qhov no yog qhov uas feem ntau cov kev txiav txim siab mus tsis ncaj ncees lawm. Cov neeg yuav khoom - thiab qee zaum cov neeg muag khoom - kho "khawm me ntsis siab dua" raws li qhov tseeb thoob ntiaj teb, thaum nyob hauv kev xyaum nws yog cov ntsiab lus - nyob ntawm nqe lus.
- Chisel khoom yog qhov kev xaiv raug thaum:
Pob zeb hardness yog tsawg mus rau nruab nrab (kwv yees Mohs 3-5), xws li limestone, coal seam phab ntsa, av nplaum pob zeb, los yog mos sandstone.
Qhov txoj kab uas hla yog nyob rau hauv 50mm - qhov ntau yam uas chisel geometry muab kev nkag tau zoo yam tsis muaj cov hniav hnav ntau dhau
Lub tshuab drilling yog ib txhais tes - tuav los yog cua - ceg pneumatic xyaum nrog tsawg cuam tshuam lub zog tso zis
Lub vev xaib muaj kev nkag mus rau lub tshuab sib tsoo, tso cai rau cov hniav hnav kom rov ua dua thiab rov qab mus rau qhov kev pabcuam
- Button bits yog qhov kev xaiv zoo dua thaum:
Pob zeb hardness txav mus rau hauv nruab nrab- nyuaj rau thaj chaw nyuaj (Mohs 5–7+), xws li granite, basalt, lossis abrasive quartzite
Tus nqi nkag mus tsis tu ncua tseem ceeb ntau dua li tus nqi tsev ib me ntsis
Kev ua haujlwm khiav mus ntev yam tsis muaj kev nkag tau yooj yim rau cov chaw tu
Qhov tseem ceeb point:nyob rau hauv mos mus rau nruab nrab pob zeb nrog lub teeb - lub luag hauj lwm xyaum, ib tug chisel me ntsis feem ntau outperforms ib pob me ntsis ntawm tus nqi -ib - meter hauv paus, vim tias nws raug nqi tsawg, xyaum ua kom nrawm nrawm, thiab tuaj yeem hloov kho ntau zaus ua ntej hloov. Ib lub pob me ntsis hauv tib yam kev mob tsuas yog overpaying rau durability uas tsim tsis xav tau.
Qhov Resharpening Factor Feem ntau cov neeg yuav khoom saib
Chisel cov khoom tuaj yeem rov kho dua ntawm -qhov chaw siv tus qauv me ntsis grinder. Thaum cov hniav poob qis los yog txhim kho lub tiaj tus, tus neeg ua haujlwm tau txais kev cob qhia rov qab txiav ntug hauv feeb. Ib qho chisel me ntsis tuaj yeem dhau los ntawm peb mus rau tsib lub voj voog rov ua dua ua ntej carbide depleted dhau mus ntxiv.
Khawm cov khoom tsis tuaj yeem rov kho dua nyob rau hauv ib qho kev nkag siab zoo. Thaum cov carbide inserts hnav tiaj los yog tawg, qhov me ntsis hloov. Rau cov chaw ua haujlwm mining tej thaj chaw deb lossis cov chaw txua txiag zeb me me hauv kev tsim cov lag luam - ib feem tseem ceeb ntawm qhov kawg - cov neeg siv lub hauv paus rau cov khoom siv tho txawv txawv txawv - qhov kev sib txawv no muaj qhov hnyav ntawm kev lag luam tiag.
Thaum koj tab tom qhia rau ib lub tuam txhab lag luam lossis tus neeg muag khoom uas muab cov mines tej thaj chaw deb nyob rau sab hnub tuaj Asia, Sub-Saharan Africa, lossis hauv South America, cov lus nug tsis yog "qhov twg xyaum nrawm dua." Nws yog "uas me ntsis ua rau drilling thaum cov saw hlau qeeb."
Ib Lub Tswv Yim Xaiv Cov Qauv
| Qhov xwm txheej | Chisel Bit | Khawm Ntsis |
|---|---|---|
| Pob zeb hardness | Mohs 3-5 (mos rau nruab nrab) | Mohs 5–7+ ( nruab nrab- nyuaj rau nyuaj) |
| Qhov taub | Tsawg dua los yog sib npaug li 50mm | Tsawg dua lossis sib npaug li 50mm (ob leeg siv) |
| Laum hom | Lub teeb pneumatic (YT28, Y24) | Lub teeb rau nruab nrab pneumatic |
| Field resharpening | Yog - ntau lub voj voog | Tsis muaj |
| Chav tsev nqi | qis | Siab dua |
| Zoo tshaj rau | Siab- ntim, nqi-sensitive, mos pob zeb | Lub pob zeb tawv, ua haujlwm ntev, nres tsawg dua |
| Tej daim ntawv thov | Coal mines, limestone quarries, thauj tog rau nkoj qhov nyob rau hauv mos tsim | Granite quarries, basalt, nyuaj- pob zeb tunneling |
Qhov no txhais li cas rau koj qhov kev txiav txim siab muab khoom
Yog tias koj cov neeg yuav khoom tau muab me me - nplai mines lossis quarries ua haujlwm hauv pob zeb mos mus rau nruab nrab nrog tes- tuav pneumatic xyaum,ib tug 36mm tapered chisel laum ntsis tsis yog ib qho kev cuam tshuam nyiaj txiag - nws yog technically raug specification.Kev ntim khoom nrog cov pob khawm muab rau koj cov neeg siv khoom tiav thiab ua haujlwm rau koj ua tus neeg muag khoom uas nkag siab txog cov xwm txheej drilling, tsis yog cov lej hauv phau ntawv xwb.
Cov neeg yuav khoom uas tau txais cov kev taw qhia zoo ntawm qhov chaw muab khoom tsis hloov cov neeg muag khoom. Cov neeg uas tau txais ib qho kev pom zoo me ntsis rau qhov muag muag - pob zeb chisel txoj haujlwm thaum kawg txiav txim siab seb puas muaj dab tsi tshwm sim.
Lub Tshuab Nruab Nrab muab 36mm tapered chisel laum cov khoom sib tw rau cov qauv teeb pom kev zoo -cov haujlwm pneumatic pob zeb xyaum, nrog 7 degree, 11 degree, thiab 12℃taper xaiv muaj.
