Ikhowudi ye-IADC imfutshane kwi "International Association of Drilling Contractors".
IKhowudi ye-IADC yeeBits ze-Tricone ichaza ukuyila kwayo kunye nezinye iimpawu zoyilo (i-SHIRT TAIL, LEG, SECTION, CUTTER).
IiKhowudi ze-IADC zenza kube lula ukuba abombi bachaze ukuba luhlobo luni na lwesuntswana lelitye abalikhangelayo kumthengisi .
IMpuma Ekude ilandela i-IADC bit classification system apho amanani amathathu okuqala ahlela isuntswana ngokokwakheka eyilelwe ukugrumba kunye noyilo olusetyenziswayo lokuzala/lotywina.
IADC ikhowudi ingcaciso yedijithi yokuqala:
I-1, 2, kunye ne-3 zikhethe iiBits zezinyo zensimbi kunye ne-1 ye-soft, i-2 ye-medium kunye ne-3 yokwakheka okuqinileyo.
I-4, 5, 6,7 kunye ne-8 zityumbe i-TUNGSTEN CARBIDE INSERT BITS yobunzima obuhlukeneyo kunye ne-4 ibe yeyona nto ithambileyo kwaye i-8 inzima kakhulu.
IADC ikhowudi ingcaciso yedijithi yesiBini:
I-1, 2, 3 kunye ne-4 ziphinda ziqhekeke kwi-formation kunye ne-1 ibe yeyona nto ithambile kwaye i-4 inzima kakhulu.
IADC ikhowudi ingcaciso yedijithi yesiThathu:
I-1 kunye ne-3: i-standard open bearing (i-non-sealed roller bearing) i-roller bit
2: Umgangatho ovulekileyo ovulekileyo wokuqhuba umoya kuphela
I-4 kunye ne-5: i-roller itywinwe ukuthwala ibhithi
I-6 kunye ne-7: ijenali itywinwe ibhithi yokuzala
Phawula:
*Umahluko phakathi kwe-1 kunye ne-3:
3 kunye ne-carbide faka kwisithende se-cone, ngelixa i-1 ngaphandle
*Umahluko phakathi kwe-4 kunye ne-5:
I-5 kunye ne-carbide ifake kwisithende se-cone, ngelixa i-4 ngaphandle.
*Umahluko phakathi kwe-6 kunye ne-7:
7 kunye ne-carbide faka kwisithende se-cone, ngelixa i-6 ngaphandle.
Inkcazo yekhowudi ye-IADC yedijithi yesiNne:
Ezi khowudi zoonobumba zilandelayo zisetyenziswa kwindawo enamanani esine ukubonisa iimpawu ezongezelelweyo:
A. Isicelo soMoya
R. IiWelds ezongeziweyo
C. Centre Jet
S. Izinyo Steel Standard
D. Ulawulo lokutenxa
X. Chisel Faka
E. Ijethi eyandisiweyo
Y. Conical Insert
G. Ukhuseleko lweGage olongezelelweyo
Z.Enye Faka imilo
J. Ukungafezeki kweJet
Iintlobo zokuthwala:
Kukho ubukhulu becala ezine (4) iintlobo zoyilo olusetyenziswa kwi-trcone drilling bits:
1) Umgangatho ovulekileyo we-Roller Bit:
Kwezi bits iicones ziya kujikeleza ngokukhululekileyo.Olu hlobo lwebit lunomqolo ongaphambili weebheringi zebhola kunye nomqolo ongasemva weebheringi eziqengqelekayo.
2): UmGangatho oVulekileyo weRoller yeBit yoKwemba umoya
Iicones ziyafana no #1 ,kodwa zinenaliti yomoya ngqo kwiicones ukupholisa iibheringi. Umoya uqukuqela kwikhowuni ngeepaseji kwiindlela ezingaphakathi kwephini.
3) Amasuntswana eRoller atywiniweyo
La masuntswana anetywina le-O-Ring elinendawo yokugcina igrisi yokuthwala ukupholisa.
Amatywina asebenza njengesithintelo ngokuchasene nodaka kunye nokusikwa ukuze kuveliswe iibheringi.
4) Journal Bearing Roller Bits
Ezi bits ziyi-oyile engqongqo / igrisi epholileyo ngeebheringi zempumlo, i-O-ring seal kunye nomdyarho wokusebenza okuphezulu.
Amasuntswana eTricone aseMpuma aneebheringi etywiniweyo yerabha kunye nentsimbi etywiniweyo.
