IADC kodhi ipfupi ye "International Association of Drilling Contractors".
IADC Code yeTricone Bits inotsanangura kugadzirwa kwayo uye mamwe maitiro ekugadzira (SHIRT TAIL, LEG, SECTION, CUTTER).
IADC Makodhi anoita kuti zvive nyore kune vanochera kutsanangura rudzi rwedombo ravari kutsvaga kumutengesi.
Kumabvazuva kunotevera iyo IADC bit classification system umo madhijiti matatu ekutanga anoisa chidimbu zvinoenderana nemagadzirirwo achakagadzirirwa kudhiraivha uye dhizaini / chisimbiso chinoshandiswa.
IADC kodhi tsananguro yedhijiti Yekutanga:
1, 2, uye 3 inosarudza Steel Tooth Bits ine 1 yekupfava, 2 yepakati uye 3 yeakaomarara maumbirwo.
4,5,6,7 uye 8 sarudza TUNGSTEN CARBIDE INSERT BITS yemhando dzakasiyana-siyana kuomarara ne 4 ichive yakapfava uye 8 yakanyanya kuoma.
IADC kodhi tsananguro yedhijitari yechipiri:
1, 2, 3 uye 4 ndezvimwezve kuparara kwekuumbwa uye 1 ari iye akapfava uye 4 akanyanya kuoma.
IADC kodhi tsananguro yetatu digit:
1 uye 3: mureza wakavhurika fani (isina-yakavharwa roller bearing) roller bit
2: Standard yakavhurika fani yekuchera mhepo chete
4 uye 5: roller yakavharwa inotakura bhiti
6 uye 7: jenari yakavharwa inobereka bhiti
Cherechedza:
*Musiyano pakati pe1 ne3:
3 ine carbide isa pachitsitsinho chekoni, nepo 1 isina
*Musiyano pakati pe4 ne5:
5 ine carbide isa pachitsitsinho chekoni, nepo 4 isina.
*Musiyano pakati pe6 ne7:
7 ine carbide isa pachitsitsinho chekoni, nepo 6 isina.
IADC kodhi tsananguro yeFout digit:
Aya mabhii macode anotevera anoshandiswa munzvimbo yechina digit kuratidza mamwe maficha:
A. Mhepo Application
R. Reinforced Welds
C. Center Jet
S. Standard Steel Zino
D. Kutsauka Kudzora
X. Chisel Insert
E. Yakawedzerwa Jet
Y. Conical Insert
G. Kuwedzera Gage Dziviriro
Z. Zvimwe Isa Shape
J. Jet Defiection
Bearing Types:
Kune kunyanya ina (4) mhando dzekutakura magadzirirwo anoshandiswa mu trcone drilling bits:
1) Standard Open Bearing Roller Bit:
Pamabhiti aya makoni anotenderera akasununguka.Iyi mhando yebhiti ine mutsara wemberi wemabearings ebhora uye kumashure kweroller bearings.
2）: Yakazaruka Yakazaruka Roller Bit yeMhepo Drilling
Makoni akafanana ne#1, asi iva nejekiseni remhepo zvakananga kumakoni kuti utonhodze mabheya.Mhepo inoyerera ichipinda mukoni nemumapassage nzira mukati mepini.(Kwete yekushandiswa kwedhaka)
3) Yakavharwa Inotakura Roller Bits
Aya mabhiti ane chisimbiso cheO-Ring chine giresi reservoir yekuburitsa kutonhora.
Zvisimbiso zvinoshanda sechidziviso kumadhaka uye kucheka kuburitsa mabearings.
4) Journal Bearing Roller Bits
Aya mabheti anonyatso oiri / girizi yakatonhodzwa nemhino, O-ring chisimbiso uye mujaho wekuita zvakanyanya.
Far Eastern Tricone Bits ane rabha yakavharwa fani uye simbi yakavharwa inobereka.
