Ungawusombulula njani Umonakalo wokuBeka kwi-Tricone Bit?

Njengenxalenye engundoqo ye-oyile kunye negesi yokomba kunye nezixhobo zobunjineli ezingenamijelo, indima "yintliziyo"i-tricone drill bit. Nangona kunjalo, ihlala isilela kwangaphambi kwexesha ngenxa yeemeko eziphantsi kakhulu, ibe yindawo ephambili yeentlungu ezithintela ukusebenza kakuhle.

Kukho izizathu ezithathu ezingundoqo zokuthwala umonakalo: 

Okokuqala, imithwalo yempembelelo ephezulu kunye nokutshintshana koxinzelelo kwi-downhole. I-radial runout kunye ne-axial extrusion yeikhowuningexesha lokomba kunokubangela ngokulula ukudinwa komzila wokuzala; 

Okwesibini, ukuhlaselwa kwe-drilling fluid kunye nokusika. Izitywina zemveli azikwazi ukwahlula ukungcola ngokufanelekileyo, okukhokelela ekugubungeleni i-abrasive bearing; okwesithathu, ukusilela kokuthambisa. Kwiindawo eziphezulu zokushisa kunye noxinzelelo oluphezulu, igrisi yokuthambisa ihlanjululwa ngokulula okanye i-carbonized, ilahlekelwa yimpembelelo yayo yokukhusela.

Ukujongana nala manqaku entlungu, i-Drillmore iphuhlise itekhnoloji ephambili ekujoliswe kuyo ekuphuculeni ngokubanzi umgangatho wokuthwala. 

Okokuqala, samkela a inkqubo yokuqinisa i-carburizing yentsimbi ephezulu yekhabhoni yechromium, okwandisa ukuqina komphezulu wokuthwala ukuya ngaphezulu kwe-HRC62 ngelixa ugcina ukuqina kombindi, ukuphumeza ukuphucuka okuphindwe kabini ekuchaseni impembelelo kunye nokumelana nokunxiba. 

Okwesibini, siye sasungula a Isitywina se-labyrinth se-multi-channel + inkqubo edibeneyo yokuthambisa i-high-pressure, ekwahlula ngokufanelekileyo uhlaselo lwe-drilling fluid kwaye ngokuqhubekayo yongeza igrisi yokuthambisa enobushushu obuphezulu ukunqanda ukusilela kokuthambisa. 

Okwesithathu, silwenze ngcono i isakhiwo sokuthwala i-roller ukusasaza umthwalo ngokulinganayo kuwo wonke umdyarho kunye nokunciphisa uxinzelelo lwendawo.
