Inyundo n'imyitozo yo gucukura umwobo

Igishushanyo cya valve cyinyundo ya DTH itanga imikorere yizewe, gukoresha umwuka muke, kubungabunga byoroshye no kwiyubaka bihendutse. Ifoto tuyikesha Caterpillar.

Inyundo ya DTH ifite santimetero 6 z'umurambararo kandi niyo yabaye iyambere yinjijwe mumurongo wibicuruzwa bya DTH.Nk'uko iyi sosiyete ibivuga, igishushanyo mbonera cyacyo gitanga imikorere yizewe, gukoresha umwuka muke, kubungabunga byoroshye no kwiyubaka bidahenze. Byongeye kandi, igishushanyo cya piston gitanga kuramba no guhererekanya ingufu neza.

Nyundo irashobora gukora hamwe na sisitemu yo mu kirere ifunitse igera kuri 500 psi.Uyu muvuduko winyuma winyuma, ufatanije nu mwuka ujyanye nibisabwa, utanga inkoni nyinshi kumunota, bigatuma umuvuduko winjira wihuta.

Iratanga kandi imyitozo yo gucukura umwobo.Bits ubu iraboneka muburyo butandukanye (santimetero 6,75) muburyo busanzwe kandi buremereye kugirango buhuze bits kumitungo n'ibisabwa akazi.

Amahitamo ya biti arimo imiterere ya karbide itandukanye (spherical, ballistic) hamwe nisura yo mumaso (conave, flat, convex), kandi ikanashyirwa mubikorwa byo kurwanya imyenda myinshi no kunonosora urutare. tanga kwinjira bidasanzwe.
