Phansi kwentengo yochungechunge lwe-dth hammer QL SD e-China

Incazelo emfushane:

1. Letha amandla aphezulu ku-drilling bit, isivinini sokumba ngokushesha kanye nokusetshenziswa komoya okuphansi ngenxa yesakhiwo esikhethekile sangaphakathi se-HD uchungechunge lwesando se-DTH esakhiwe ngokuvumelana nethiyori entsha yokumba amadwala.
2. Ukusebenza okubushelelezi kanye nempilo ende yesevisi yesando se-DTH ngenxa yezinto ezisezingeni eliphezulu zensimbi ye-alloy kanye nobuchwepheshe bokucubungula obuthuthukisiwe obushintshiwe.
3. Izinga lenkinga eliphansi futhi kulula ukugcinwa ngenxa yokuhlanganisa okulula, okuthembekile nokulula nokuhlakaza isakhiwo sangaphakathi sesando.
4. Kulula ukusuka kancane esando ngenxa yentambo enamakhanda amaningi exhuma i-chuck nesilinda sesando.
5. Ishintshaniswa ne-DTH bit kanye nepayipi lokubhoboza

Imininingwane Yomkhiqizo

Omaka bomkhiqizo

Ibanga lezando le-TDS Down the Hole liyahluka ukusuka ku-2.5 kuya ku-12 amayintshi ububanzi futhi ibhithi ye-DTH isukela ku-3” kuya ku-18” ububanzi.Insimbi yekhwalithi ephezulu ehlanganiswe nekhwalithi ye-carbide ezandleni zonjiniyela bethu abangochwepheshe nabanolwazi iqinisekisa kuphela imikhiqizo yokumba esezingeni eliphakeme kakhulu.Izando zethu zikhiqiza ukungena okuphezulu ekusebenziseni uphethiloli ophansi.Ngisho nomfutho womoya ophansi, unikeza ukusebenza okuphezulu.Izando zethu ze-DTH zisetshenziselwa ukumba imithombo Yamanzi, ezimayini nasenkwalini kanye nasembonini yezokwakha.Amabhithi e-DTH ayatholakala ngezitayela zobuso ezihlukene njenge-concave, i-convex ne-flat.
