Ma Soft Rocks Drilling Roller Cone Bits IADC437 Sealed Bearing ndi Long TC Insert Bits

Ma tricone roller bits a IADC437 ali ndi ma tungsten carbide inserts ataliatali kwambiri omwe amayenera kukumba miyala yofewa kwambiri.

Miyala yofewa nthawi zonse imakhala yodzaza ndi zinthu zomata zomwe zimaphimba mano zomwe zimapangitsa kuti mano azigwedezeka.

Ma tungsten carbide inserts afupiafupi amatha kuboola miyala yolimba mosavuta, koma sangathe kuboola miyala yofewa komanso yomata, kuyika bit-balling kudzateteza kuti miyala isasweke.
IADC437 ndi yayitali kwambiri chifukwa TC imayika ma roller cone bits, ndi yoyenera kuboola mapangidwe ofewa mwachangu kwambiri.
Magawo Ogwirira Ntchito
Ma roller cone awa amagwiritsidwa ntchito popanga zinthu zofewa zomwe zimakhala ndi mphamvu zochepa zopondereza komanso luso lalikulu lobowola, monga dongo, miyala yamatope, choko, gypsum, mchere, miyala yamwala yofewa, ndi zina zotero.
