Tsawg Cua-Pressure DTH Rauj
Lub down-the-qhovdth cogyog ib qho khoom siv uas siv cov cua compressed los ua lub zog thiab siv cov lus tsa suab ntawm lub piston hauvraujlos cuam tshuam lub laum me ntsis kom tawg lub pob zeb. Lub down-the-qhovdth cogyog ib qho cuab yeej ua haujlwm ntawm qhov kev xyaum ua haujlwm hauv qab. Raws li kev ua haujlwm siab ntawm lubdth cog, nws tuaj yeem muab faib ua qhov tsis tshua muaj siabdth cog(ua haujlwm siab yog 0.5 ~ 0.7Mpa), nruab nrab-siabdth cog(0.7 ~ 1.2Mpa) thiab siab-siabdth cog(siab tshaj 1.2Mpa); raws li txoj kev faib cov pa roj thiab cov yam ntxwv ntawm cov qauvdth cog, nws tuaj yeem muab faib ua valved thiab valveless hom; raws li kev tsim ntawm lub hauv paus los ntawm lub qhov ntawm down-the-qhovdth cog, nws muaj peev xwm muab faib ua dog dig down-the-qhovdth cogthiab rov qab ncig down-lub-qhovdth cog.
Daim ntawv thov:
Nws yog dav siv nyob rau hauv loj-scale qhib-qhov thiab underground ore mining, anchoring engineering, quarrying thiab pob zeb drilling, dej zoo geothermal mining, kev tsim kho engineering pob zeb drilling thiab loj-scale engineering siv., lwm.
Nta
1 Kev khiav hauj lwm huab cua siab nyob nruab nrab ntawm 0.5Mpa thiab0.7 uaMpa
2 Valveless rauj.
3 Cov qauv yooj yim, yooj yim rau kev sib sau thiab disassemble, lub neej ntev.
4 Kev cuam tshuam ntau dua thiab nrawm dua drilling.
5 Tsawg cua siv thiab txo cov roj noj. Ib lub qhov tuaj yeem drilled rau ntawm daim tshev valve los muab kev txiav tawm kom zoo dua.
6 Tshwj xeeb yog tsim rau quarrying.
