Khodi ya IADC ndi yachidule ya "International Association of Drilling Contractors".
Khodi ya IADC ya Tricone Bits imatanthawuza kapangidwe kake kokhala ndi mawonekedwe ena (SHIRT TAIL, LEG, SECTION, CUTTER).
Ma Code a IADC amapangitsa kuti zikhale zosavuta kuti obowola afotokoze mtundu wa rock bit yomwe akufuna kwa ogulitsa.
Kum'mawa kwa Far kumatsatira kachitidwe ka IADC kagawo kakang'ono komwe manambala atatu oyamba amayika pang'onopang'ono molingana ndi kapangidwe kake kabowoleredwe ndi kamangidwe kake.
Kufotokozera kwa IADC kwa Nambala Yoyamba:
1, 2, ndi 3 amasankha Mabiti a Steel Tooth ndi 1 yofewa, 2 yapakati ndi 3 yamagulu olimba.
4,5,6,7 ndi 8 amasankha TUNGSTEN CARBIDE INSERT BITS ya kuuma kosiyanasiyana ndi 4 kukhala yofewa kwambiri ndi 8 yolimba kwambiri.
Kufotokozera kwa IADC kwa Nambala Yachiwiri:
1, 2, 3 ndi 4 ndi kuwonongeka kwina kwa mapangidwe ndi 1 kukhala wofewa kwambiri ndi 4 wovuta kwambiri.
Kufotokozera kwa IADC pa Nambala Yachitatu:
1 ndi 3: wodzigudubuza wokhazikika (wopanda kusindikizidwa) wodzigudubuza pang'ono
2: Standard lotseguka pobowola mpweya kokha
4 ndi 5: chodzigudubuza chosindikizidwa chonyamula
6 ndi 7: magazini yosindikizidwa yosindikizidwa
Zindikirani:
* Kusiyana pakati pa 1 ndi 3:
3 yokhala ndi carbide yoyika pachidendene cha chulucho, pomwe 1 wopanda
* Kusiyana pakati pa 4 ndi 5:
5 yokhala ndi carbide ikani pachidendene cha chulucho, pomwe 4 opanda.
* Kusiyana pakati pa 6 ndi 7:
7 yokhala ndi carbide pa chidendene cha chulucho, pomwe 6 opanda.
Kufotokozera kwa nambala ya IADC kwa manambala aFout:
Zilembo zotsatirazi zimagwiritsidwa ntchito pa nambala yachinayi kusonyeza zina zowonjezera:
A. Air Application
R. Zowotcherera Zowonjezeredwa
C. Center Jet
S. Standard Steel Dzino
D. Kuwongolera Kupatuka
X. Chisel Insert
E. Jeti Yowonjezera
Y. Conical Insert
G. Chitetezo Chowonjezera cha Gage
Z
J. Jet Defiection
Mitundu Yonyamula:
Pali mitundu inayi (4) yamapangidwe omwe amagwiritsidwa ntchito pobowola trcione bits:
1) Standard Open Bearing Roller Bit:
Pazinthu izi ma cones amazungulira momasuka. Mtundu uwu wa bit uli ndi mzere wakutsogolo wa mayendedwe a mpira ndi mzere wakumbuyo wa mayendedwe odzigudubuza.
2）: Standard Open Bearing Roller Bit for Air Drilling
Ma cones ndi ofanana ndi #1, koma jekeseni mpweya mwachindunji ku cones kuti aziziziritsa mayendedwe. Mpweya umalowa mu koni kudzera munjira za mkati mwa pini. (Osati zamatope)
3) Zosindikizidwa Zokhala ndi Roller Bits
Ma bits awa ali ndi chisindikizo cha O-Ring chokhala ndi mosungiramo mafuta kuti aziziziritsa.
Zisindikizozo zimagwira ntchito ngati chotchinga pamatope ndi kudula kuti zipangitse mabere.
4) Journal Bearing Roller Bits
Tizidutswa tating'onoting'ono tamafuta / mafuta okhazikika ndi mphuno, O-ring seal komanso mpikisano wochita bwino kwambiri.
Far Eastern Tricone Bits ali ndi zomata zomata mphira komanso zomata zachitsulo.
