ISando seDTH soxinzelelo lomoya oluphantsi
Umngxuma osezantsidth isandosisixhobo esisebenzisa umoya ocinezelweyo njengomthombo wamandla kwaye sisebenzisa intshukumo yokubuyisela yepistonisandoukuphembelela isuntswana le-drill ukuqhekeza ilitye. Umngxuma osezantsidth isandosisixhobo esisebenzayo se-drill esezantsi-umngxuma. Ngokoxinzelelo lokusebenza lwedth isando, inokwahlulwa ibe luxinzelelo oluphantsidth isando(uxinzelelo lokusebenza yi-0.5 ~ 0.7Mpa), uxinzelelo oluphakathidth isando(0.7 ~ 1.2Mpa) kunye noxinzelelo oluphezuludth isando(ngaphezu kwe-1.2Mpa); ngokwendlela yokusasazwa kwerhasi kunye neempawu zesakhiwo sedth isando, inokwahlulwa ibe ziindidi ezinevalvu kunye nezingenavalo; ngokokwakheka kwendawo esembindini ngomngxuma ongaphantsi komngxumadth isando, inokwahlulwa ngokwesiqhelo phantsi komngxumadth isandokunye nokujikeleza okujikelezayo phantsi komngxumadth isando.
Isicelo :
Isetyenziswa ngokubanzi kumgodi omkhulu ovulekileyo kunye nomgodi wentsimbi ekrwada ngaphantsi komhlaba, ubunjineli be-anchoring, ukwembiwa kwenkwali kunye nokugrumba amatye, imigodi yamanzi eshushu, imigodi yobunjineli bokwembiwa kwamatye kunye nokwakhiwa kobunjineli obukhulu., njl.
Iimbonakalo
1 Uxinzelelo lomoya olusebenzayo luphakathi kwe-0.5uMpa kunye0.7Mpa
2 izando ezingenavalo.
3 Ulwakhiwo olulula, kulula ukudibanisa kunye nokuqhawula, ubomi obude.
I-4 ifuthe leempembelelo eziphezulu kunye nesantya esikhawulezayo sokomba.
5 Ukusetyenziswa komoya okuphantsi kunye nokusetyenziswa kwe-oyile ephantsi. Umngxuma unokugrunjwa kwi-valve yokutshekisha ukubonelela ngokukhutshwa kwe-cuttings esebenzayo.
6 Ilungele ngakumbi ukwembiwa.
