Izando zeDTH zoxinzelelo loMoya oPhakathi-Phantsi
BRIA,BR2A kunyeI-BR3Uthotho lwe-DTH Hammers zenzelwe ukusebenza ngokufanelekileyo kuxinzelelo lomoya ophantsi kunye noxinzelelo lomoya ophakathi, usebenzisa iibhithi ze-BR.
Iimpawu eziphambili zezi zilandelayo:
1. Uxinzelelo lomoya olusebenzayo luphakathi kwe-0.7Mpa kunye ne-1.75Mpa.
2. Iihamile ezingenavalo.
3. Isakhiwo esilula, kulula ukudibanisa kunye nokuqhaqha, ubomi obude.
4. Ukuphindaphinda kwempembelelo ephezulu kunye nesantya sokumba ngokukhawuleza.
5. ukusetyenziswa komoya okuphantsi kunye nokusetyenziswa kweoli ephantsi.Umngxuma unokugrunjwa kwi-valve yokutshekisha ukubonelela ngokukhutshwa kwe-cuttings esebenzayo.
6. Ngokukodwa afanele ukugrunjwa.
