Ungawuxazulula Kanjani Umonakalo Wokuthwala ku-Tricone Bit?

Njengengxenye ewumnyombo yokumba uwoyela negesi kanye nemishini yobunjiniyela engenawo amanzi, okuhambisana nayo "inhliziyo"i-tricone drill bit. Kodwa-ke, ngokuvamile ihluleka ngaphambi kwesikhathi ngenxa yezimo ezimbi kakhulu ze-downhole, ibe iphuzu elibalulekile lobuhlungu elikhawulela ukusebenza kahle kokumba.

Kunezizathu ezintathu ezibalulekile zokuthwala umonakalo: 

Okokuqala, imithwalo ephezulu yomthelela kanye nezingcindezi ezishintshanayo ziyancipha. I-radial runout kanye ne-axial extrusion ye-ikhoningesikhathi sokubhoboza kungabangela kalula ukukhathala ukuchitheka komgwaqo othwalayo; 

Okwesibili, ukuhlaselwa kwe-drilling fluid kanye ne-cuttings. Izigxivizo zendabuko azikwazi ukuhlukanisa ukungcola ngokuphumelelayo, okuholela ekugqokeni kwe-abrasive of the bear; okwesithathu, ukwehluleka kokugcoba. Ezimweni ezishisa kakhulu nezinomfutho ophezulu, amafutha okugcoba ahlanjululwa kalula noma afakwe i-carbonized, alahlekelwe umphumela wawo wokuvikela.

Ukuze kubhekwane nalawa maphuzu ezinhlungu, i-Drillmore ithuthukise ubuchwepheshe obuthathu obuhlosiwe ukuze ithuthukise ngokugcwele ikhwalithi yokuthwala. 

Okokuqala, samukela a inqubo yokuqinisa i-carburizing yensimbi ene-high-carbon chromium, okwandisa ubulukhuni bobuso be-bearing ibe ngaphezu kwe-HRC62 kuyilapho kugcinwa ukuqina komnyombo, kufeza ukuthuthuka okukabili ekumelaneni nomthelela nokumelana nokuguga. 

Okwesibili, sisungule a multi-channel labyrinth seal + high-pressure lubrication uhlelo oludidiyelwe, okuhlukanisa ngokuphumelelayo ukuhlasela koketshezi lokumba futhi ngokuqhubekayo yengeze amafutha okugcoba okushisa aphezulu ukuze kugwenywe ukwehluleka ukugcotshwa. 

Okwesithathu, sithuthukise i- I-spherical roller bearing structure ukusabalalisa umthwalo ngokulinganayo kuwo wonke umgwaqo womjaho kanye nokunciphisa ukugxila kwengcindezi yendawo.
