Isicelo
I-roller cone bit iyithuluzi elisetshenziswa kakhulu ekubholeni i-petroleum kanye nokumba i-geological.I-Tricone bit inomsebenzi wokuba nomthelela, ukuchoboza kanye nokugunda amatshe ekwakhekeni, ngakho-ke ingakwazi ukuzivumelanisa nokwakheka okuthambile, okuphakathi nendawo nokuqinile.I-cone bit ingahlukaniswa ibe yi-milling (amazinyo ensimbi) i-cone bit kanye ne-TCI cone bit ngokusho kohlobo lwamazinyo.
Izici
Ngokusho kwezinto zokusika, zingahlukaniswa zibe izinyo lensimbi (izinyo lokugaya) kanye ne-tungsten carbide insert (TCI) yezinyo le-roller cone bit.
I-TCI Tricone bits ukumba ukuze akheke amatshe aqinile.
Ukwakheka okumaphakathi kwe-TCI trione bits kufaka phakathi ukufakwa kwe-chisel tungsten carbide okunamandla emigqeni yesithende kanye nemigqa yangaphakathi.
Lo mklamo unikeza izinga lokumba ngokushesha futhi wanezela ukuqina kwesakhiwo sokusika ekubunjweni okuqinile okuphakathi nendawo.I-O-ring yerabha ye-HSN ihlinzeka ngokuvaleka okwanele ukuze ithwale ukuqina.
Izingcezu ze-TCI ze-tricone eziqinile zingasetshenziswa ukubhola ukwakheka okuqinile nokunama-abrasive.I-Wear resistance tungsten carbide inserts isetshenziswa emigqeni engaphandle ukuvimbela ukulahleka kwe-bit gauge.Izinombolo eziphezulu zokufakwa okumise okwe-hemispherical zisetshenziswa kuyo yonke imigqa ukunikeza ukuqina komsiki nempilo ende.

| 227 | 0.35~0,95 | 150-50 | Ukwakheka okuqinile okumaphakathi okunamandla amakhulu okucindezela, okufana ne-abrasive shale, i-limestone, i-sandstone, i-dolomite, i-gypsum eqinile, imabula, njll. |
| Qaphela: Imikhawulo ephezulu ye-WOB ne-RPM kuthebula elingenhla akufanele isetshenziswe kanyekanye. | |||
