Ikhodi ye-IADC imfushane yokuthi “Inhlangano Yamazwe Ngamazwe Yosonkontileka Bokubhoboza”.
Ikhodi ye-IADC yamabhithi e-Tricone ichaza ukwakheka kwayo okuzalayo nezinye izici zokuklama ( SHIRT TAIL, LEG, SECTION, CUTTER).
Amakhodi e-IADC enza kube lula ngababhola ukuthi bachaze ukuthi yiluphi uhlobo lwe-rock bit abalufunayo kumphakeli .
IMpumalanga Ekude ilandela i-IADC bit classification system lapho amadijithi amathathu okuqala ehlukanisa ibhithi ngokuya ngendlela eklanyelwe ukuyibhoboza kanye nomklamo wokuthwala/uphawu osetshenzisiwe.
Incazelo yekhodi ye-IADC yedijithi yokuqala:
1, 2, kanye no-3 qoka Izingcezu Zezinyo Zensimbi no-1 kokuthambile, 2 kokumaphakathi no-3 kokwakheka okuqinile.
4,5,6,7 kanye no-8 qoka i-TUNGSTEN CARBIDE INSERT BITS yokwakheka okuhlukahlukene kobulukhuni kanye no-4 athambile kakhulu futhi 8 aqine kakhulu.
Incazelo yekhodi ye-IADC yedijithi Yesibili:
U-1, 2, 3 kanye no-4 ziwukuhlukana okuqhubekayo kokwakheka lapho u-1 ethambile futhi 4 enzima kakhulu.
Incazelo yekhodi ye-IADC yedijithi Yesithathu:
1 kanye no-3: ibhithi yerola elijwayelekile (elingavaliwe).
2: I-bearing evulekile evamile yokubhoboza umoya kuphela
4 kanye no-5: i-roller evalwe nge-bearing bit
6 kanye no-7: ijenali evaliwe enebhithi
Qaphela:
*Umehluko phakathi koku-1 no-3:
3 nge-carbide ifaka esithendeni sekhoni, kuyilapho u-1 ngaphandle
*Umehluko phakathi kuka-4 no-5:
5 nge-carbide ifaka esithendeni se-cone, kuyilapho 4 ngaphandle.
*Umehluko phakathi kuka-6 no-7:
7 nge-carbide ifaka esithendeni sekhoni, kuyilapho 6 ngaphandle.
Incazelo yekhodi ye-IADC yedijithi ye-Fout:
Amakhodi ezinhlamvu alandelayo asetshenziswa endaweni enedijithi yesine ukukhombisa izici ezengeziwe:
A. Isicelo somoya
R. Ama-Weld Aqinisiwe
C. Centre Jet
S. Izinyo Lensimbi Elijwayelekile
D. Ukulawula Ukuchezuka
X. Ishizi Faka
E. Indiza Enwetshiwe
Y. I-Conical Insert
G. Ukuvikelwa Kwegeji Eyengeziwe
Z.Enye Faka Umumo
J. Jet Defiection
Izinhlobo zokuthwala:
Kunezinhlobo ezine (4) ngokuyinhloko zemiklamo yokufaka esetshenziswa kumabhithi okumba ama-trcone:
1) I-Standard Open Bearing Roller Bit:
Kulezi zingcezu ama-cones azojikeleza ngokukhululekile.Lolu hlobo lwebhithi lunomugqa wangaphambili wamabheringi amabhola kanye nomugqa ongemuva wama-roller bearings.
2）: I-Standard Open Bearing Roller Bit for Air Drilling
Izigaxa ziyafana ne-#1, kodwa zijovwe komoya ngqo kumakhoni ukuze upholise ama-bearings. Umoya ugelezela kukhoni ezindleleni ezingaphakathi kwephini.(Hhayi okokufaka udaka)
3) Ama-Roller Bits Avaliwe
Lezi zingcezu zine-O-Ring seal ene-grease reservoir yokuthela ukupholisa.
Lezi zimvu zamanzi zisebenza njengesithiyo odakeni nasekusikeni ukuze ziveze ama-bearings.
I-4) I-Journal Bearing Roller Bits
Lezi zingcezu zingamafutha/amafutha apholile afakwe emakhaleni, i-O-ring seal kanye nomjaho wokusebenza okuphezulu.
I-Far Eastern Tricone Bits ine-rabha evalwe uphawu kanye nensimbi evaliwe.
