Ukugrumba okungcwatywayo kunye nokudilika komngxuma zezona ngxaki zixhaphakileyo neziyingxaki kwiiprojekthi ezininzi ezintsonkothileyo zolwakhiwo lwejoloji.Kunzima ukuqinisekisa umgangatho kunye nokusebenza kakuhle kokomba ngobuchwepheshe obuqhelekileyo bokugaya.
Nangona kunjalo, ukubonakala kombhobho olandelayo kusombulula ngokugqibeleleyo le ngxaki.Ikhusela umngxuma wesitsala-manzi ngesingxobo sokugrumba ngokufanelekileyo, kwaye ibuyisela iqula eligobayo ngesiphumo esisisikhokelo esiqinileyo sombhobho.Okwangoku, izixhobo zokugrumba imibhobho ye-eccentric kunye ne-centric zisetyenziswa kakhulu e-China.Ngenxa yodonga olungqindilili lwesuntswana langaphandle, isiphumo sothumelo lwamandla empembelelo yesixhobo sokugrumba esigxile asilunganga njengesixhobo sokomba eccentric kulwakhiwo olufanayo lokuvula.Kuphela xa i-diameter yesixhobo sokugaya isikhulu kwaye i-impactor enoxinzelelo oluphezulu lomoya ikhethiwe, umphumo ungcono, kodwa iindleko zokuvelisa ziphezulu kakhulu kunezo zixhobo zokugaya i-eccentric.Isixhobo sokugaya umbhobho we-Eccentric asinayo kuphela ububanzi bomngxuma omkhulu, kodwa sinesakhiwo esilula, ixabiso eliphantsi lokuvelisa kunye nokulula ukulisebenzisa, ngoko lisetyenziswe ngokubanzi.
Umgaqo wokusebenza we-eccentric bit ngulo:
I-1, i-DTH hammer eccentric kunye nenkqubo yokugrumba umbhobho, nokuba yeyiphi i-eccentric enezixhobo zokugaya umbhobho xa i-drill drilling igrunjwe yi-eccentric inkulu kunomngxuma we-casing diameter, kwaye xa ubhobhoza kumhlaba omiswe kwangaphambili, ukudibanisa, kunye nezixhobo zokugaya umbhobho. inokwenziwa kunye nedamitha enkulu yangaphandle yesixhobo sokomba umbhobho ngaphantsi kwe-diameter yangaphakathi yeebhutsi zetyhubhu, i-casing, ukususa ngezixhobo zokomba umbhobho, i-casing ingahlala ikwi-formation yokukhusela udonga lomngxuma.
2. Xa ubhobhoza ngokuqhelekileyo, umoya oxinyiweyo onikezelwa yi-compressor yomoya ungena kwi-DTH impactor ngokusebenzisa i-drill kunye ne-drill pipe ukuze isebenze.I-piston ye-impactor ichaphazela i-normalizer yesixhobo sokomba kunye nombhobho, kwaye i-normalizer idlulisela i-wave shock kunye noxinzelelo lwe-bit kwi-bit eccentric kunye ne-bit central ukuphula ilitye ezantsi komngxuma.
3. Xa ubunzima be-casing bukhulu kunokuxhatshazwa kwe-friction yokwakheka kwindonga ye-casing, i-casing iya kulandela ubunzima bayo.
4. Umngxuma owenziwe nge-eccentric bit umkhulu kunobukhulu obungaphandle bobubanzi be-casing, ukwenzela ukuba i-casing ingathintelwa yidwala phantsi komngxuma kwaye ilandele phezulu.
