IADC637 9 7/8 tricone bits yobowola zitsime zamadzi yomwe ilipo kuti ipange miyala yolimba

IADC 637 (Code X) TCI journal sealed bearing tricone bit, yokhala ndi chitetezo cha gauge, yapangidwa mwapadera kuti igwiritsidwe ntchito pakupanga zolimba ndi mphamvu yayikulu yokakamiza kuyambira 100-150 MPa (14,500-23,000 PSI) — phindu lalikulu lomwe limawonetsedwa mu mayankho a makasitomala. Ndi kukula kwake kuyambira 9 5/8” mpaka 9 7/8”, imagwiritsa ntchito zinthu za tungsten kuti zigwirizane ndi zofunikira pakuyenda kwa matope pakubowola zitsime zamadzi, ndipo imagwirizanitsidwa ndi ma jet okhazikika a mbali zitatu. Makasitomala amanena kuti ndi ofooka kwambiri komanso kuyenda kwa matope kokhazikika, zomwe zimathandiza kuti ntchito ikhale yogwira mtima pakupanga zolimba. Pakadali pano, kapangidwe ka chitetezo cha bearing ndi gauge kotsekedwa kamawonjezera nthawi yake yogwirira ntchito, ndikuwonjezera magwiridwe antchito onse akubowola komanso kugwiritsa ntchito ndalama zochepa.kuchitapo kanthu.
