Middle-Low Cua Siab DTH Hammers
BRIA,BR2A thiabBR3A series DTH Hammers yog tsim los ua haujlwm zoo ntawm huab cua tsis tshua muaj siab thiab nruab nrab cua siab, siv BR series khoom.
Lub ntsiab nta yog raws li nram no:
1. Kev khiav hauj lwm huab cua siab nyob nruab nrab ntawm 0.7Mpa thiab 1.75Mpa.
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. txo qis cua thiab kev siv roj tsawg.Ib lub qhov tuaj yeem drilled rau ntawm daim tshev valve los muab kev txiav tawm kom zoo dua.
6. Tshwj xeeb tshaj yog tsim rau quarrying.
