IADC637 9 7/8 tricone bits zo gucukura amariba y'amazi ziri mu bubiko bwo gukora amabuye akomeye

IADC 637 (Code X) TCI journal sealed bearing tricone bit, ifite uburinzi bwa gauge, yagenewe by'umwihariko imiterere ikomeye ifite imbaraga zo gukanda kuva kuri 100-150 MPa (14.500-23.000 PSI) - inyungu nyamukuru igaragarira mu bitekerezo by'abakiriya. Ifite ingano ya 9 5/8” kugeza kuri 9 7/8”, ikoresha ibikoresho bya tungsten kugira ngo ihuze n'ibisabwa mu gucukura amariba y'amazi, kandi ihuzwa n'indege zisanzwe zo mu mpande eshatu. Abakiriya bavuga ko idashira neza kandi ko ikora neza mu miterere ikomeye. Hagati aho, igishushanyo mbonera cy'uburinzi bwa gauge n'ubwaguke byongera igihe cyo kuyikoresha, yongera imikorere myiza yo gucukura no kugabanya ikiguzi.gukora cyane.
