Cov khoom siv dov kaw IADC216 5 7/8inches (149mm)
Kev piav qhia txog khoom
TCI Tricone Bit tseem hu ua rotary drill bit yog qhov kev daws teeb meem zoo tshaj plaws rau cov pob zeb mos, nruab nrab, lossis tawv, nws txuas nrog lub qia laum thiab tig nrog nws, thiab tsav cov cones kom nias rau ntawm pob zeb. Txhua lub cone tig ib ncig ntawm lub axis ntawm nws ceg thiab peb lub cones tib lub sijhawm tig ib ncig ntawm lub hauv paus ntsis. Cov tungsten carbide inserts ntawm lub plhaub cone ua rau cov qauv tsim kom tawg hauv qab qhov hnyav ntawm lub ntsis thiab qhov cuam tshuam ntawm lub cone tig, cov khib nyiab yuav raug tso tawm mus rau qhov los ntawm cua compression.
Cov pob zeb tricone muaj ntau hom sib txawv, thiab tuaj yeem daws tau ntau yam pob zeb sib txawv. Nws yog ib qho tseem ceeb kom paub hom pob zeb uas koj tab tom tho thaum xaiv lub pob zeb tho. Cov pob zeb nruab nrab TCI tricone muaj cov yam ntxwv:
Cov cuab yeej txiav tungsten carbide ntxig rau ntawm cov kab pob taws thiab cov kab sab hauv. Tus qauv tsim no muab qhov nrawm nrawm thiab ntxiv qhov ruaj khov ntawm cov qauv txiav hauv nruab nrab mus rau nruab nrab nyuaj rau cov mations. Lub nplhaib roj hmab HSN muab kev sib khi txaus rau kev ua haujlwm ntev.
