Phansi emgodini dth sd mission 6” isando kanye nenani elincane

Incazelo emfushane:

I-TDS ingumkhiqizi osezingeni lomhlaba wemikhiqizo yokumba i-percussion.Njengoba sinesipiliyoni seminyaka engaphezu kwengu-20, ukuzibophezela kwethu ekwenzeni kahle kuqinisekisa umkhiqizo onokwethenjelwa ozokwenza njalo.Sisebenzisa ubuchwepheshe bakamuva kwezobunjiniyela ukukhiqiza imiklamo esezingeni eliphezulu.Sisebenzisa izindlela ezihlangabezana nezindinganiso ze-aerospace ekukhiqizeni izando nebhithi yekhwalithi ephezulu

Umlayezo I-imeyili

Imininingwane Yomkhiqizo

Omaka bomkhiqizo

Ibanga eliphelele losayizi wembobo wokumba imbobo eqhumayo nge-DTH ngu-90 mm ukuya ku-254 mm (3 ½”–10″).Izimbobo ezincane eziqhumayo ngokuvamile zibholwa kusetshenziswa i-tophammer, futhi izimbobo ezinkulu ngokuvamile zisebenzisa imishini yokuzungeza.

Kwezinye izinhlelo zokusebenza, njengokumba isisekelo, izando ze-DTH zingasetshenziswa ngebhithi eyodwa kumasayizi wembobo kufika ku-.750 mm (30″).Ngamayunithi amaningi esando e-CD (ama-Cluster drill) bhoboza izimbobo ezifika ku-70″ noma 1778 mm.

Njengomthetho wesithupha, imbobo encane kunazo zonke isando se-DTH esingamba usayizi wayo ovamile.Isando esingu-4 intshi sizobhoboza imbobo engama-intshi angu-4 (102 mm).Isici esikhawulelayo ububanzi obungaphandle besando, ngoba, njengoba ububanzi bembobo kuncipha, ukugeleza komoya kukhawulelwe.Ubukhulu bembobo yosayizi wokukhiqiza ubungako besando esihlanganisa ne-intshi engu-1, ngakho-ke ngesando esingama-intshi angu-4 ubukhulu bembobo bungama-intshi angu-5 (127–130 mm).

Ukukhetha isando esifanele kunqunywa kakhulu ubukhulu bembobo kanye nohlobo lokwakheka kwamatshe.Ngokufanelekile, ubukhulu besando kufanele buhambisane nobukhulu bembobo edingekayo ngokuseduze ngangokunokwenzeka, kushiye isikhala esanele sokusikwa ukuze kukhishwe umgodi.
