Iimpawu zoyilo: I-Tricone Drill Bit Body.

Umzimba we-tricone drilling bit uquka:

1.uqhagamshelwano lwentambo, okanye amanqina, ancamathisela amasuntswana etricone kumtya.
2.isikhonkwane sokuthwala ekufakwe kuso iicones.
3.idama lokuthambisa, eliqulathe unikezelo lwesixokelelwano sokuthambisa kwibheringi, umjelo wamanzi apho ulwelo lokomba luhamba ukuya khona.icocekile emngxunyenis.

Icandelo lomzimba womntu ngamnye, kubandakanywa nezikhonkwane zokuzala, zenziwe ngoomatshini ukusuka kwi-forging okanye ukuphosa i-nickel-chromium-molybdenum alloy steel ye-carburized grade.Inxalenye yepini yokuthwala ikhethwa ngokukhethiweyo (i-surface lukhuni) ukubonelela ngetyala elinzulu, elingagugiyo.Eli candelo ke licinywe ngeoli liqiniswe kwaye lifudumale, okubangela ukunxitywa kwe-bearing surface.

Icandelo ngalinye lomzimba libandakanya umlenze kunye nephini lokuzala, i-Tricone Three Cones Drill Bits inamacandelo amathathu.Amacandelo ngamanye adityaniswe kunye ukwenza i-bit body epheleleyo.

IrolaamasuntswanaTricone Drill Bit Shanks.

I-shank ye-Rock Roller Tricone Bits idibanisa umzimba kwi-bit sub okanye i-drill collar.Uxhulumaniso lwentambo yi-API intambo eqhelekileyo, intambo engqukuva.Iisayizi zoqhagamshelo zilungele amasuntswana edrill ahlukeneyo.

Umphezulu we-shank usetyenziselwa ukuchonga.Iqulethe ulwazi olunje:

1.bit ubukhulu intshi
2.inombolo yendibano
3.uhlobo
4.uphawu lokuthengisa lomenzi
5.inombolo yothotho
6.IADC ikhowudi

I-shank kunye negxalaba zibonelela ngokutywinwa kwe-fluid phakathi kwe-tricone bit kunye nomtya we-drill.Iintambo aziyi kwenza isitywina soxinzelelo kwaye ziya kubangelaukuhlamba umbhobhoingxaki ukuba i-cone Drill Bit ayenziwanga kakuhle.Kubalulekile, ke ngoko, ukuqinisekisa ukuba isihlalo se-shank kunye negxalaba zicocekile.
