Iindidi ezahlukeneyo zeMigodi kunye neeBits zoKwemba kakuhle

Ukwembiwa kwemigodi ngamasuntswana akruqulayo emingxuma agqobhozayo agqobhoze imathiriyeli yamatye athambileyo naqinileyo. Zisetyenziswa emigodini, ekugrunjweni kwamaqula, ekwarini, etoneleni, ekwakhiweni, kuphononongo lwejoloji, kunye nezicelo zokuqhushumba.

Ukwembiwa kwemigodi kunye namasuntswana okomba abonisa uqhagamshelo oludityanisiweyo lokuncamatheliswa kumtya wokubhola kunye nomzimba ongenanto apho ulwelo lwe-drill lujikeleziswa. Ulwelo lwe-drill luyafuneka ukuze kucinywe i-drill cuttings, ukupholisa intwana, kunye nokuzinzisa udonga lwequla. Iintlobo zamasuntswana okomba amaqula ziquka oku kulandelayo:

I-Tri-cone okanye i-roller bitsziqulathe iicones ezintathu ezinamazinyo, nganye ineengile yejenali egxunyekwe kwiaxis ephambili yebit. I-angle yejenali iguqulwa ngokobulukhuni bokubunjwa. Amazinyo ekhowuni nganye adibana kwelinye ukuze agqobhoze umhlaba oqinileyo. I-bit iqhutywa yi-weight-on-bit (WOB) ngelixa itsalwa yintshukumo ejikelezayo yentloko ye-drill bit.

Phantsi-kumngxuma (DTH) amasuntswana esandozisetyenziswa nge Down-the-hole iihamile zokomba imingxuma ngokusebenzisa uluhlu olubanzi lwamatye iintlobo. Ngokudityaniswa neehamile ze-DTH, i-drill hammer bits ziyilelwe nge-splined drive yokujikeleza isuntswana emhlabeni. Amasuntswana e-DTH ngamasuntswana entloko esisigxina ane-conical okanye i-chisel bit efakelwayo elungelelaniswe kwi-matrix malunga ne-drill bit head. Ubumbeko lwentloko yesuntswana inokuba convex, concave, okanye flat.

Amasuntswana ePDCkunye nokufakwa kwe-polycrystalline diamond compact (PDC) kunokubhekiswa kuyo njengamasuntswana ePDC. Ngokungafaniyo namasuntswana e-tricone, i-PDC drill bits yimizimba enye engenazo iindawo ezihambayo kwaye zenziwe ukuba zihlale; yonke isuntswana yenzelwe ukusebenza, ukungaguquguquki kunye nokuthembeka. Khetha iMatrix okanye intsimbi ephezulu ukuze ihambelane nezicelo ezahlukeneyo zokomba.

Amaqhosha amaqhoshaziyafana namasuntswana e-DTH entloko esisigxina ene-conical okanye i-chisel bit efakelwayo elungelelaniswe kwi-matrix malunga ne-drill bit head. Ubumbeko lwentloko yesuntswana inokuba convex, concave, okanye flat. I-Button bit yintwana engqukuva ilungele uninzi lwamatye aqinileyo, izicelo zokomba ihamile ephezulu.

Iibhithi ezinqamlezayo kunye neebhithi zetshiselingamasuntswana anentloko eqinileyo enentsimbi eqinileyo okanye iincakuba zecarbide. Iibhithi zetshizi zichazwa ngencakuba enye ngelixa iibhithi ezinqamlezileyo zinencakuba ezimbini nangaphezulu ezinqumla kumbindi we bit. Iiblades zidla ngokucolwa phantsi ukuya kwindawo yokusika.
