I-Rotary drilling rig

Kunezinhlobo ezimbili: eyodwa isemshinini wokumba ojikelezayo ngesisekelo sokwengezwa komshini womthelela, ikakhulukazi ekubholani okujikelezayo, lapho uhlangana nongqimba lwamatshe olunomthelela wokumba umgodi wokumba onezinjongo ezimbili, ukukwazi ukuzivumelanisa nezimo eziqinile ezitabeni ezihlukahlukene;Okunye wumthelela kanye nesenzo sokuzungeza okuhlanganiswe nensimbi yokumba umthombo, njenge-pneumatic DTH hammer drill.I-DTH hammer drill (FIG. 5) yenziwe nge-cylinder liner kanye nepiston ehamba phezulu naphansi ku-cylinder liner.Ingxenye engezansi ye-cylinder liner ixhunywe ne-drill bit, futhi indawo engenhla ixhunywe nepayipi yokubhoboza ngokusebenzisa i-joint threaded.Umoya onomfutho ophezulu ohlinzekwa yi-compressor yomoya ungu-0.7 ~ 1.4 mpa ngevalvu yokuhlola ngaphezu kwepiston, isisabalalisi somoya nendawo yokungena komoya ngaphansi kwepiston, kanye nemvamisa yomthelela yepiston iphushwa phezulu naphansi njengo-700~1200. izikhathi/umzuzu, ukuze ipiston ivamise ukuba nomthelela kubhithi lokubhoboza.Ukuthuthukisa ikhono le-drill bit yokubhoboza idwala.Ngesikhathi esifanayo, ipayipi yokubhoboza ijikeleza ngesivinini esiphansi se-35 ~ 60 RPM.Umoya ovela emigodini engaphezulu nephansi yepiston ugeleza wehle uye ebhithini ukuze upholise kancane futhi ukhiphe ama-cuttings anembobo engezansi ekhanda lomthombo.Isakhiwo sengxenye yokugeza kahle ejikelezayo nezungezayo ngokuyisisekelo sifana naleyo yokubhoboza okujikelezayo okunomoya ocindezelweyo, kanti ibhithi elisetshenziswa i-tungsten carbide ball tooth bit noma i-roller cone bit.I-pneumatic DTH yokubhoboza isando ingasetshenziselwa ukubhoboza Imithombo ejulile kumadwala aqinile.Isivinini sokubhoboza siphezulu, futhi isivinini sokubhoboza asinciphi ngenxa yokwanda kokujula kokumba, futhi umgodi wokubhoboza uqondile.

Ukuze uvumelane nezidingo zokumba ama-strata ahlukene, ukuthuthukisa ukusebenza kahle kokumba, i-drilling rig iyi-multi-purpose drilling rig kanye nokudluliswa okugcwele kwe-hydraulic kanye nokulawula isiqondiso sentuthuko: okungukuthi, i-rig yokumba enezinhlobonhlobo zemishini nezinye izinsimbi. , ingasebenzisa isando esijikelezayo, i-DTH nezinye izindlela zokumba;Ukugeza amanzi ngodaka, ukuwashwa komoya ocindezelwe kanye nokugeleza okuhle nokuhlehlisa ukugeleza kwamanzi ukuwashwa kahle nakho kungasetshenziswa.
