Amathuluzi Okugaya E-DTH Drilling Rigs-Drill Pipes

Iqhaza le-drill rod ukuthumela i- impactor phansi kwembobo, ukudlulisa i-torque kanye nomfutho we-shaft, nokuletha umoya ocindezelwe ku-impactor ngembobo yawo emaphakathi.Ipayipi lokubhoboza lingaphansi kwemithwalo eyinkimbinkimbi efana nokudlidliza komthelela, itorque, kanye nomfutho we-axial, futhi libhekene nokuhuzuka kwe-sandblasting ebusweni be-slag ekhishwa odongeni lwembobo kanye nepayipi lokubhoboza.Ngakho-ke, induku yokubhoboza iyadingeka ukuze ibe namandla anele, ukuqina kanye nokuqina komthelela.Ipayipi lokubhoboza ngokuvamile lenziwa ngepayipi lensimbi engenamthungo elinengalo ewugqinsi engenalutho.Ubukhulu bobubanzi bepayipi lokubhoboza kufanele buhlangabezane nezidingo zokukhishwa kwe-slag.

Iziphetho ezimbili zenduku yokubhoboza zinemicu yokuxhuma, isiphetho esisodwa sixhunywe kumshini wokuhambisa umoya ojikelezayo, kanti esinye isiphetho sixhunywe ne- impactor.I-drill bit ifakwe ekugcineni kwe- impactor.Lapho ubhoboza, umshini wokuhambisa umoya ojikelezayo ushayela ithuluzi lokubhoboza ukuze lijikeleze futhi linikeze umoya ocindezelwe entweni yokubhoboza engenalutho.I- impactor ithinta i-drill bit ukubhoboza idwala.Umoya ocindezelwe ukhipha i-rock ballast embobeni.I-propulsion mechanism igcina i-rotary air supply mechanism kanye nethuluzi lokumba liqhubekele phambili.Phambili.

Ubukhulu bobubanzi bepayipi lokubhoboza kufanele buhlangabezane nezidingo zokususwa kwe-ballast.Njengoba umthamo wokunikezwa komoya uhlala njalo, isivinini somoya esibuyayo sokukhishwa kwe-rock ballast sincike kubukhulu bendawo ye-annular cross-sectional phakathi kodonga lwembobo kanye nepayipi lokubhoboza.Ngomgodi onobubanzi obuthile, ubukhulu be-diameter yangaphandle yepayipi yokubhoboza, kukhulu ukubuya kwesivinini somoya.
