Kodhi yeIADC ipfupiso ye "International Association of Drilling Contractors".
Kodhi yeIADC yeTricone Bits inotsanangura dhizaini yayo yemabheyaringi nezvimwe zvinhu zvekugadzira (SHIRT TAIL, LEG, SECTION, CUTTER).
Makodhi eIADC anoita kuti zvive nyore kune vanochera matombo kutsanangura rudzi rwedombo ravari kutsvaga kumutengesi.
Far Eastern inotevera nzira yekuisa mabhiti muzvikamu zveIADC umo manhamba matatu ekutanga anoisa mabhiti muzvikamu zvichienderana nekugadzirwa kwaakagadzirirwa kuboora uye dhizaini yebearing/seal inoshandiswa.
Tsananguro yekodhi yeIADC yenhamba yekutanga:
1, 2, uye 3 zvinoratidza Steel Tooth Bits ne 1 ye soft, 2 ye medium uye 3 ye hard formations.
4, 5, 6, 7 na 8 zvinoratidza TUNGSTEN CARBIDE INSERT BITS pakuoma kwechimiro kwakasiyana, 4 iriyo yakapfava uye 8 iriyo yakaoma.
Tsananguro yekodhi yeIADC yenhamba yechipiri:
1, 2, 3 na 4 mamwe magadzirirwo emuviri, 1 iriyo yakapfava uye 4 iriyo yakaoma.
Tsananguro yekodhi yeIADC yenhamba yechitatu:
1 ne3: bheyaringi yakavhurika yakajairika (bheyaringi isina kuvharwa) bheyaringi rinotenderera
2: Bearing yakavhurika yakajairika yekuchera mhepo chete
4 ne5: roller yakavharwa bearing bit
6 ne7: chidimbu chebheyaringi chakavharirwa
Cherechedza:
*Musiyano uripo pakati pe1 ne3:
3 ine kabhidhidhi pachitsitsinho chekoni, nepo imwe isina
*Musiyano uripo pakati pe4 ne5:
5 ine kabhidhidhi pachitsitsinho chekoni, nepo 4 isina.
*Musiyano uripo pakati pe6 ne7:
7 ine kabhidhidhi pachitsitsinho chekoni, nepo 6 isina.
Tsananguro yekodhi yeIADC yenhamba yechina:

Mhando dzeBheari:
Kune mhando ina (4) dzemabheyaringi anoshandiswa mukugadzira trcione drilling bits:
1) Chiyero cheRoller Bit chakavhurika:
Pazvidimbu izvi, makoni anotenderera zvakasununguka. Rudzi urwu rwechikamu rune mutsetse wepamberi wemabhora uye mutsetse wekumashure wemaroller bearings.
2）: Standard Open Bearing Roller Bit yeKuchera Mhepo
Makone akafanana ne #1, asi ane mweya unopinzwa zvakananga kumakone kuti mabheringi atonhore. Mhepo inoyerera ichipinda mukone ichipinda nepakati pepini. (Haisi yekushandiswa mumatope)
3） Zvidimbu zveRoller zveBearing zvakavharwa
Zvidimbu izvi zvine chisimbiso cheO-Ring chine grisi rekuchengetedza kuti bere ritonhore.
Zvisimbiso izvi zvinoshanda sechidziviriro kubva kumatope nezvidimbu kuti zviratidze mabheringi.
4) Zvidimbu zveRoller zveJenari
Zvidimbu izvi zvinotonhodzwa nemafuta/mafuta chete nemhino, chisimbiso cheO-ring uye kumhanya kuti zvishande zvakanaka.
Mabhiti eTricone ekuFar Eastern ane rabha yakavharwa uye simbi yakavharwa.
