I. Los ntawm Lub Hwj Chim Loj
• Pneumatic Pob Zeb Laum: Tsim los ntawm cov cua compressed, kuj yooj yim hauv cov qauv thiab yooj yim los tswj, haum rau drilling nruab nrab- pob zeb nyuaj thiab nyuaj, thiab feem ntau siv dav hauv cov chaw engineering.
• Hydraulic Pob Zeb Laum: Siv siab - roj siab ua qhov nruab nrab, muaj lub zog siab ceev, tsis tshua muaj suab nrov, thiab ua haujlwm siab. Nws yog ib qho yooj yim los kho cov kev txwv thiab tswj tau, feem ntau siv hauv tunneling, hydropower, thiab quarrying rau nruab nrab mus rau qhov tob qhov kev ua haujlwm.
• Fais Pob Zeb Laum: Tsav los ntawm lub tshuab hluav taws xob los ntawm lub crank- txuas pas nrig mechanism, nws muaj kev siv lub zog siab, huv si thiab qis- suab nrov, thiab haum rau me me mus rau nruab nrab txoj kab uas hla, luv luv thiab ntiav qhov kev tsim kho nrog lub zog ruaj khov.
• Internal Combustion Pob Zeb Laum: Siv lub cav roj av los muab kev cuam tshuam lub zog, yog lub xov tooj ntawm tes, tsim nyog rau cov xwm txheej tsis muaj hluav taws xob / cua, thiab ua kom yooj yim txav chaw ceev hauv roob thiab thaj chaw ib puag ncig.
II. Los ntawm Kev Txhawb Nqa thiab Kev Txhawb Nqa
• Handheld: Lub teeb yuag, nqa tau yooj yim thiab hloov tau yooj yim hauv lub qhov layout, haum rau me me txoj kab uas hla, luv luv thiab ntiav lub qhov. • Outrigger hom (pneumatic ceg hom): Kev txhawb nqa thiab kev txhawb nqa yog muab los ntawm pneumatic ob txhais ceg, txo qis zog siv zog thiab txhim kho kev ua haujlwm drilling. Dav siv nyob rau hauv mines thiab tunnel excavation.
• Hom Telescopic (hom sab saud): Lub laum caj npab yog coaxially teem nrog lub ntsiab chav tsev, tshwj xeeb tshaj yog rau upward drilling tej yam kev mob.
• Qhia kev tsheb ciav hlau hom: Rigidly txuas nrog lub drilling rig los yog kev taw qhia rail, muab qhov chaw siab thiab ruaj khov, haum rau nruab nrab - qhov tob, qhov ntev drilling, thiab siab - qhov ua tau zoo.
III. Los ntawm Crushing Mechanism thiab Drilling Method
• Kev cuam tshuam pob zeb: tso siab rau qhov siab - zaus cuam tshuam ntawm lub piston ntawm lub laum me ntsis txhawm rau txhawm rau pob zeb. Haum rau cov pob zeb tawv thiab abrasive, nrog rau qhov zoo dua hauv kev ua haujlwm drilling hauv cov pob zeb nyuaj.
• Rotary pob zeb xyaum: Feem ntau siv txiav txiav, ua ke nrog axial thrust rau pob zeb nruam tawg. Feem ntau siv rau hauv cov pob zeb mos thiab cov coal seams, nrog kev co thiab suab nrov.
• Impact-rotary (rotary-}impact) pob zeb laum: Sib txuas cov kev cuam tshuam thiab kev txiav rotary, sib koom ua ke qhov zoo ntawm ob lub tswv yim, haum rau ntau yam kev ua haujlwm ntawm nruab nrab- nyuaj rau pob zeb nyuaj. • Kev piav qhia ntxiv: Hauv kev xyaum ua engineering, tsis yog- pob zeb tshuab- txoj kev tawg kuj tseem muaj (xws li siab- lub dav hlau dej siab, thermal, laser, ultrasonic vibration txiav, plasma nplaim, thiab lwm yam), uas yog siv los ua cov txheej txheem ntxiv lossis tshwj xeeb hauv cov xwm txheej tshwj xeeb.
IV. Los ntawm Drill Rotation Method thiab Frequency Parameters
• Drilling Method
• Internal Rotation Type: Lub laum me ntsis yog tsav los tig intermittently los ntawm ib tug kauv pas nrig ratchet mechanism, uas ua rau ib tug compact qauv.
• Sab Nraud Kev Sib Txuas Hom: Lub laum me ntsis yog tsav los tig tsis tu ncua los ntawm lub tshuab cua ywj siab lossis hydraulic lub cev muaj zog, muab lub zog zoo dua thiab tswj tau.
• Kev cuam tshuam theem
• Hauv engineering, zaus feem ntau raug faib ua qis- zaus (kwv yees Tsawg dua lossis sib npaug li 42 Hz) thiab siab - zaus. Feem ntau, pneumatic pob zeb xyaum ua haujlwm ntawm zaus ntawm 20-50 Hz, thaum hydraulic pob zeb xyaum tuaj yeem ncav cuag 30-70 Hz. Ntau zaus muaj txiaj ntsig zoo rau kev txhim kho pob zeb- rhuav tshem kev ua haujlwm thiab lub qhov phab ntsa tsim kom zoo.
V. Cov Lus Qhia Xaiv (Cov Lus Qhia luv luv)
• Xaiv cov txheej txheem crushing thiab qauv raws li pob zeb tej yam kev mob (hardness, toughness, pob qij txha, thiab lwm yam): Impact/impact-rotary yog nyiam rau cov pob zeb nyuaj; rotary yog tsim rau cov pob zeb mos.
• Xav txog lub borehole txoj kab uas hla thiab qhov tob: Handheld/outrigger hom yog haum rau me me, ntiav qhov; hydraulic qhia rail hom lossis drilling rig nrog kev ua haujlwm siab yog nyiam rau nruab nrab - qhov tob.
• Sib tw ntawm -qhov chaw zog thiab kev tiv thaiv ib puag ncig: Hluav taws xob raug xaiv yog tias muaj lub zog ruaj khov; hydraulic raug xaiv rau kev ua haujlwm siab thiab tsis muaj suab nrov; sab hauv combustion raug xaiv yog tias tsis muaj hluav taws xob lossis roj; pneumatic raug xaiv yog tias muaj roj txaus.
• Hais txog qhov chaw ua haujlwm thiab kev nyab xeeb: Ua tib zoo mloog lub suab nrov, kev co, kev tswj plua plav, thiab qhov cua; configure ntub drilling, tshem tawm plua plav, thiab kev co damping li yog tias tsim nyog.
