Feem ntau siv cais- hom down- lub - qhov drilling rigs nyob rau hauv qhov av engineering feem ntau muab faib ua peb pawg:
Lub teeb- lub luag haujlwm rigs: Nyhav 3-5 tons, nrog rau txoj kab uas hla ntawm 80-120mm, haum rau cov pob zeb mos thiab cov chaw kaw.
Nruab nrab- lub luag haujlwm rigs: Nruab nrog ob lub hwj chim taub hau, drilling qhov tob txog li 50 meters, ua tau zoo heev rau nruab nrab- cov pob zeb nyuaj.
Hnyav- lub luag haujlwm rigs: Hydraulic system siab tshaj 25MPa, nrog tsim - hauv cov khoom siv tshem tawm plua plav, tshwj xeeb yog tsim los rau cov txheej txheem nyuaj heev xws li granite.
Cov ntsuas kev ua tau zoo tseem ceeb rau qhov chaw tsim kho sib txawv:
Pob zeb khoom: Rau Mohs hardness hauv qab 5, ib qho kev cuam tshuam lub zog ntawm 800J yog haum; rau Mohs hardness saum 6, 1200J yog yuav tsum tau. Qauv J thiab siab dua
Kev txwv qhov chaw: Qhov qhov siab ntawm qhov siab tsawg dua 3 meters yuav tsum muaj kev sib tw folding caj npab tsim.
Environmental requirements: Rau kev tsim kho hauv nroog, kev siv hluav taws xob hybrid raug pom zoo, nrog cov suab nrov tswj qis dua 75 decibels.
Peb txoj cai golden rau kev ua haujlwm thiab kev saib xyuas:
Laum pas nrig tu: Ntxuav cov xov txhua 8 teev ntawm kev ua haujlwm; ua qhov sib nqus particle kuaj tom qab 200 teev ntawm kev siv cumulative.
Kev tswj cov roj lubrication: Ntxiv cov roj tshwj xeeb rau qhov cuam tshuam txhua 2 teev; kho cov roj viscosity raws li ambient kub.
Kev twv twv ua txhaum: Tam sim ntawd xyuas lub tshuab txias yog tias cov roj hydraulic kub siab tshaj 65 degree; nres lub tshuab thiab tshawb xyuas yog tias muaj kev hloov pauv siab tshaj 15%.
