IADC code yog luv rau "International Association of Drilling Contractors".
IADC Code rau Tricone Bits txhais nws cov kabmob tsim thiab lwm yam qauv tsim (SHIRT TAIL, LEG, SECTION, CUTTER).
IADC Codes ua rau nws yooj yim dua rau cov tshuab tho los piav qhia seb cov pob zeb zoo li cas lawv tab tom nrhiav rau tus neeg muag khoom.
Far Eastern ua raws li IADC cov kev faib me me uas thawj peb tus lej faib cov me me raws li kev tsim nws yog tsim los xyaum thiab cov kabmob / foob tsim siv.
IADC code piav qhia rau Thawj tus lej:
1,2, thiab 3 xaiv cov hniav nyiaj hniav kub nrog 1 rau muag muag, 2 rau nruab nrab thiab 3 rau kev tsim nyuaj.
4,5,6,7 thiab 8 xaiv TUNGSTEN CARBIDE INSERT BITS rau txawv formations hardness nrog 4 yog softest thiab 8 hardest.
IADC code piav qhia rau tus lej thib ob:
1,2,3 thiab 4 yog qhov sib ntxiv ntawm kev tsim nrog 1 yog qhov softest thiab 4 hardest.
IADC code piav qhia rau tus lej thib peb:
1 thiab 3: txheem qhib bearing (tsis-sealed roller bearing) cov menyuam me
2: Standard qhib bearing rau huab cua drilling nkaus xwb
4 thiab 5: cov menyuam kaw cov kabmob me ntsis
6 thiab 7: phau ntawv kaw cov kabmob me ntsis
Nco tseg:
* Qhov txawv ntawm 1 thiab 3:
3 nrog carbide ntxig rau pob taws ntawm lub khob hliav qab, thaum 1 tsis muaj
* Qhov txawv ntawm 4 thiab 5:
5 nrog carbide ntxig rau pob taws ntawm lub khob hliav qab, thaum 4 tsis muaj.
* Qhov txawv ntawm 6 thiab 7:
7 nrog carbide ntxig rau pob taws ntawm lub khob hliav qab, thaum 6 tsis muaj.
IADC code piav qhia rau Tus lej Plaub:
Cov kab ntawv hauv qab no yog siv rau hauv txoj haujlwm thib plaub los qhia txog cov yam ntxwv ntxiv:
A. Air Application
R. Reinforced Welds
C. Center Jet
S. Txheem Hlau Hniav
D. Deviation Control
X. Chisel Insert
E. Lub dav hlau txuas ntxiv
Y. Conical ntxig
G. Extra Gage Protection
Z .Lwm Insert Shape
J. Dav Hlau Defiection
Hom Bearing:
Feem ntau muaj plaub (4) hom kabmob tsim siv hauv trcione drilling khoom:
1) Standard Open Bearing Roller Bit:
Ntawm cov khoom no lub cones yuav tig dawb do.Cov hom me me no muaj ib kab pem hauv ntej ntawm pob bearings thiab ib kab rov qab ntawm cov menyuam bearings.
2) Standard Open Bearing Roller Bit rau Cua Drilling
Cones zoo ib yam li #1, tab sis muaj cua txhaj ncaj qha rau lub khob kom txias cov kabmob.Cua ntws mus rau hauv lub khob hliav qab los ntawm txoj hauv kev hauv tus pin.(Tsis yog rau cov av nkos)
3) Sealed Bearing Roller Khoom
Cov khoom no muaj O-Ring foob nrog roj reservoir rau kev ua kom txias.
Cov ntsaws ruaj ruaj ua raws li kev thaiv cov av nkos thiab txiav los ua cov kabmob.
4) Phau ntawv Cov Kabmob Cov Menyuam Cov Khoom
Cov khoom no nruj me ntsis roj / roj txias nrog lub qhov ntswg bearings, O-ring foob thiab kev sib tw rau kev ua haujlwm siab tshaj plaws.
Far Eastern Tricone Bits muaj roj hmab kaw cov kabmob thiab cov kabmob hlau kaw.
