Ikhodi ye-IADC ifushaniswa nelithi “Inhlangano Yamazwe Ngamazwe Yabakhi Bemishini Yokubhoboza”.
Ikhodi ye-IADC yama-Tricone Bits ichaza ukwakheka kwayo kwamabhere kanye nezinye izici zokuklama (I-SHIRT TAIL, LEG, SECTION, CUTTER).
Amakhodi e-IADC enza kube lula ngababholi ukuchaza uhlobo lwe-rock bit abalufunayo kumhlinzeki.
I-Far Eastern ilandela uhlelo lokuhlukanisa ama-bit lwe-IADC lapho izinombolo ezintathu zokuqala zihlukanisa khona i-bit ngokwendlela eklanyelwe ukubhoboza ngayo kanye nomklamo we-bearing/seal osetshenzisiwe.
Incazelo yekhodi ye-IADC yedijithi yokuqala:
1, 2, kanye no-3 bachaza ama-Steel Tooth Bits ano-1 othambile, 2 ophakathi nendawo kanye no-3 wokwakheka okuqinile.
4, 5, 6, 7 kanye no-8 bachaza ama-TUNGSTEN CARBIDE INSERT BITS ngokuqina okuhlukahlukene kokwakheka, u-4 uthambile kakhulu kanti u-8 unzima kakhulu.
Incazelo yekhodi ye-IADC yedijithi yesibili:
U-1, 2, 3 no-4 bangukuhlukana okwengeziwe kokwakheka, u-1 uthambile kakhulu kanti u-4 unzima kakhulu.
Incazelo yekhodi ye-IADC yedijithi yesithathu:
1 no-3: i-roller bit ejwayelekile yokuthwala (i-roller bearing engavaliwe)
2: Ibhere elivulekile elijwayelekile lokubhoboza umoya kuphela
4 no-5: i-roller sealed bearing bit
6 no-7: i-jenali evaliwe i-bearing bit
Qaphela:
*Umehluko phakathi kuka-1 no-3:
3 ene-carbide insert esithendeni sekhoni, kanti eyodwa ayinayo
*Umehluko phakathi kuka-4 no-5:
5 ene-carbide insert esithendeni sekhoni, kuyilapho 4 ingenayo.
*Umehluko phakathi kuka-6 no-7:
7 ene-carbide insert esithendeni sekhoni, kuyilapho engu-6 ingenayo.
Incazelo yekhodi ye-IADC yezinombolo ezine:
Amakhodi ezinhlamvu alandelayo asetshenziswa endaweni yezinombolo ezine ukukhombisa izici ezengeziwe:
A. Isicelo Somoya
R. Ama-Weld Aqinisiwe
C. Indiza Ephakathi
Izinyo Lensimbi Elijwayelekile le-S.
D. Ukulawula Ukuphambuka
I-X. Insert ye-Chisel
E. Ijethi Enwetshiwe
I-Y. Conical Insert
G. Ukuvikelwa Kwesango Elengeziwe
Z. Okunye Ukuma Kokufaka
Ukulahleka Kwejethi kaJ.
Izinhlobo Zokuthwala:
Kunezinhlobo ezine (4) eziyinhloko zemiklamo yokuthwala esetshenziswa kuma-bits okubhoboza i-trcione:
1) I-Roller Bit Ejwayelekile Evulekile Yokuthwala:
Kulezi zingcezu amakhoni azojikeleza ngokukhululeka. Lolu hlobo lwe-bit lunomugqa wangaphambili wama-ball bearing kanye nomugqa wangemuva wama-roller bearing.
2）: I-Roller Bit Ejwayelekile Yokubethela Okuvulekile Yokubhoboza Umoya
Amakhoni afana ne-#1, kodwa anomjovo womoya ngqo kumakhoni ukuze apholise amabheringi. Umoya ugeleza ungene kukhoni ngezindlela zokudlula ngaphakathi kwephini. (Akuvunyelwe ukusetshenziswa ngodaka)
3） Ama-Roller Bits Ahlanganisiwe
Lezi zingcezu zinesivalo se-O-Ring esinesithako samafutha sokupholisa ama-bearing.
Lezi zivalo zisebenza njengesivikelo esivimbela udaka kanye nokusikwa ukuze kuvele amabheringi.
4) Ama-Roller Bits e-Journal Bearing
Lezi zingcezu zipholile ngo-oyela/amafutha kuphela nge-nose bearings, i-O-ring seal kanye nomjaho wokusebenza okuphezulu.
Ama-Tricone Bits aseMpumalanga Ekude ane-bearing evalwe ngerabha kanye ne-bearing evalwe ngensimbi.
