Kub Muag Downhole Dth Rauj Bit Chaw Tsim Tshuaj Nqe
Laum rauj yog ib yam ntawm cov cuab yeej siv hauv kev xyaum drilling, Pneumatic DTH rauj kuj hu ua pneumatic impactor, pneumatic DTH.Powered los ntawm compressed cua nruab nrab, siv compressed cua zog los tsim ib tug nruam hauv qab ntawm lub qhov cuam tshuam load zog cuab tam.Compressed cua thiab tuaj yeem ua ob npaug li ntxuav Kong media.Pneumatic impactor nrog kev kub siab thiab tsis tshua muaj siab, valve thiab valveless ntawm cov ntsiab lus.Feem ntau pneumatic impactor ncaj qha txuas nrog carbide laum me ntsis stelidium txoj kev cuam tshuam rau pob zeb crushed, low-speed rotary drilling tsis coring comprehensive.Feem ntau siv nyob rau hauv hydrology thiab dej zoo drilling, geological drilling tsis muaj core, geological kev puas tsuaj tiv thaiv engineering thiab mine drilling thiab lwm yam teb.Haum rau kev siv pob zeb thiab pob zeb nyuaj, teeb tsa cov qauv tshwj xeeb ntawm cov laum kuj tuaj yeem siv rau hauv cov av mos.ROP feem ntau siab dua li qhov hydraulic impactor drilling, tab sis yuav tsum muaj cua compressor loj dua nrog lub peev xwm, ntau dua roj noj, suab nrov thiab plua plav paug.Drilling qhov tob los ntawm qib dej hauv av, dej cawv.
