Ikhowudi ye-IADC imfutshane elithi “International Association of Drilling Contractors”.
Ikhowudi ye-IADC yeeTricone Bits ichaza uyilo lwayo lweebheringi kunye nezinye iimpawu zoyilo (i-SHIRT TAIL, LEG, SECTION, CUTTER).
Iikhowudi ze-IADC zenza kube lula kubagrumbi ukuchaza uhlobo lweqhekeza lelitye abalifunayo kumthengisi.
IMpuma Ekude ilandela inkqubo yokwahlulwahlulwa kweebhithi ze-IADC apho amanani amathathu okuqala ahlulahlula ibhithi ngokwendlela eyilelwe ukugrumba ngayo kunye noyilo lwebheri/isitywina olusetyenzisiweyo.
Inkcazo yekhowudi ye-IADC yenombolo yokuqala:
I-1, 2, kunye ne-3 zibonisa iiSteel Tooth Bits apho i-1 ikwindawo ethambileyo, i-2 ikwindawo ephakathi kunye ne-3 kwiindawo eziqinileyo.
4, 5, 6, 7 kunye no 8 bachaza i-TUNGSTEN CARBIDE INSERT BITS kwiindlela ezahlukeneyo zokuqina, u-4 uyeyona ithambileyo kwaye u-8 uyeyona inzima.
Inkcazo yekhowudi ye-IADC yedijithi yesibini:
I-1, 2, 3 kunye ne-4 zezinye iindlela zokwahlulahlula ukwakheka, apho i-1 ithambileyo kwaye i-4 inzima.
Inkcazo yekhowudi ye-IADC yenombolo yesithathu:
1 kunye no-3: i-roller bit evulekileyo eqhelekileyo (i-roller bearing engatywinwanga)
2: Ibheyari evulekileyo eqhelekileyo yokugrumba umoya kuphela
4 kunye no-5: i-roller sealed bearing bit
6 kunye no-7: i-jenali etywiniweyo yebheri
Phawula:
*Umahluko phakathi kwe-1 kunye ne-3:
3 kunye ne-carbide insert kwisithende sekhowuni, ngelixa enye ingenayo
*Umahluko phakathi kwe-4 kunye ne-5:
5 kunye ne-carbide insert kwisithende sekhowuni, ngelixa 4 ngaphandle kwayo.
*Umahluko phakathi kwe-6 kunye ne-7:
7 kunye ne-carbide insert kwisithende sekhowuni, ngelixa 6 ngaphandle kwayo.
Inkcazo yekhowudi ye-IADC yenombolo yesine:
Ezi khowudi zilandelayo zoonobumba zisetyenziswa kwindawo yesine ukubonisa ezinye iimpawu:
A. Ukusetyenziswa komoya
R. IiWelds eziQinisekisiweyo
C. Inqwelo moya esembindini
Izinyo lentsimbi esemgangathweni ye-S.
D. Ulawulo lokuphambuka
I-X. Itshiseli yokufaka
E. Ijethi Eyandisiweyo
I-Y. I-Conical Insert
G. Ukhuseleko olongezelelweyo lweGage
Z.Okunye Faka Imilo
Ukuphambuka kweJet kaJ.
Iintlobo zeebhearing:
Kukho iintlobo ezine (4) zoyilo lweebheringi ezisetyenziswa kwiibhithi zokubhola ze-trcione:
1) I-Roller Bit evulekileyo yokuthwala esemgangathweni:
Kwezi nxalenye, iikhowuni ziya kujika ngokukhululekileyo. Olu hlobo lwento lunomqolo ongaphambili weebheringi zebhola kunye nomqolo ongasemva weebheringi zerola.
2）: I-Standard Open Bearing Roller Bit yoMgca woMoya
Iikhowuni zifana ne #1, kodwa zinomoya ofakwa ngqo kwiikhowuni ukuze zipholise iibheringi. Umoya ungena kwikhowuni ngeendlela zokudlula ngaphakathi kwephini. (Ayisetyenziselwa ukufakelwa udaka)
3） Iibhithi zeRoller ezitywiniweyo
Ezi bhithi zinesitywina se-O-Ring esine-grisi reservoir yokupholisa iibheringi.
Izitywini zisebenza njengesithintelo eludakeni nakwiziqwenga ukuze ziveze iibheringi.
4) Iibhithi zeRoller zeJenali ezithwala iiBheri
Ezi bhithi zipholile ngeoyile/igrisi kuphela ngee-nose bearings, i-O-ring seal kunye nokhuphiswano lokusebenza okuphezulu.
IiTricone Bits zaseMpuma Ekude zine-raber sealed bearing kunye ne-metal sealed bearing.
