I-Low Air-Pressure DTH Hammer
I-down-the-holedth isandoiyidivayisi esebenzisa umoya ocindezelwe njengomthombo wamandla futhi isebenzisa ukunyakaza okuphindaphindayo kwepistonisandoukuba nomthelela ku-drill bit ukuphula idwala. I-down-the-holedth isandoiyithuluzi elisebenzayo lokubhoboza phansi-umgodi. Ngokusho kwengcindezi yokusebenza kwedth isando, ingahlukaniswa ibe yingcindezi ephansidth isando(ingcindezi yokusebenza ingu-0.5~0.7Mpa), ingcindezi ephakathidth isando(0.7~1.2Mpa) kanye nengcindezi ephezuludth isando(ngaphezulu kwe-1.2Mpa); ngokwendlela yokusabalalisa igesi kanye nezici zesakhiwo se-dth isando, ingahlukaniswa ngezinhlobo ze-valve kanye ne-valve; ngokusho kokwakheka kwendawo ephakathi ngembobo ye-down-the-holedth isando, ingahlukaniswa ngokwejwayelekile phansi-umgodidth isandonokuhlehlisa ukuzungeza phansi emgodinidth isando.
Isicelo :
Isetshenziswa kakhulu ezimayini ezinkulu zemigodi evulekile nezingaphansi komhlaba, ubunjiniyela be-anchoring, ukumba izinkwali nokumba amatshe, izimayini zomthombo wamanzi we-geothermal, ubunjiniyela bokumba amatshe kanye nokwakhiwa kobunjiniyela obukhulu., njll.
Izici
1 Umfutho womoya osebenzayo uphakathi kuka-0.5uMpa kanye0.7Mpa
2 Izando ezingenazivali.
3 Isakhiwo esilula, kulula ukusihlanganisa nokusiqaqa, ubude bempilo.
4 Imvamisa ephezulu yomthelela kanye nesivinini sokubhola esisheshayo.
5 Ukusetshenziswa komoya okuphansi nokusetshenziswa kancane kukawoyela. Imbobo ingabhotshwa kuvalve yokuhlola ukuze kuhlinzekwe ukukhishwa kwe-cuttings okuphumelelayo.
6 Ilungele kakhulu ukumba inkwali.
