Mefuta e fapaneng ea lisebelisoa tsa Rock le Roller Cone Drill Bits lubrication system e sebelisetsoang ts'ireletso ea libere.Sistimi ea khale e kenyelletsa ho sebelisa mokelikeli oa ho cheka e le lisebelisoa, ha sistimi ea morao-rao e sebelisa mafura bakeng sa ho tlotsa.Mekelikeli ea ho cheka e nang le lintho tse thata tse abrasive e lokela ho ba karolo e lekantsoeng ea nako e telele 'me e sebelisoa ka seoelo e le setlolo ho likotoana tsa sejoale-joale.Ka mohlala, li-cones tsa li-tricone bits, li-roller cone drill bits li kenngoa ka har'a likoranta joalokaha ho bontšitsoe moralo o ka tlase.
Likotoana tsa ho cheka, likotoana tsa Tricone tsa Rock Roller Cone Drill Bit Bearing Design
Mefuta e Meraro e Tloaelehileng ea Moralo oa Bearings e Sebelisitsoeng ka har'a li-tricone bits tsa rock Roller Cone Drill Bits:
1.Roller bits bearings System, e etsang kopano e ka ntle ho tšehetsa ho kenya radial (kapa WOB)
2.Ball bearings System, e hanelang meroalo ea longitudinal kapa ea ho sututsa hape e thusa ho boloka likhoune likoranteng.
3.A friction Bearing System, kopanong ea nko e thusang ho tšehetsa phallo ea mahlaseli.Sehlahisoa se khethehileng se hatelloa ka nkong ea khoune.Sena se kopana le pilot pilot ho jenale ho hlahisa coefficient e tlase ea khohlano ho thibela ho tsietsana le ho khathala.
Lisebelisoa tsohle tsa ho jara li tlameha ho etsoa ka tšepe e thata e nang le khanyetso e phahameng ea ho phunya le ho robeha tlas'a mojaro o boima oo ba lokelang ho o tšehetsa.Joalo ka likarolo tsohle tsa li-roller cone drill, kalafo ea mocheso e sebelisetsoang ho matlafatsa tšepe.
Lintlha tsa bohlokoa ka ho fetisisa tsa moralo oa kopano ea li-bearings ke ho fumaneha ha sebaka.Ha e le hantle, bethe e lokela ho ba kholo ka ho lekaneng ho tšehetsa phallo e kentsoeng, empa sena se tlameha ho leka-lekana khahlanong le matla a koranta le khetla ea khoune e ka bang mosebetsi oa bophara ba jenale le botenya ba khetla ea kholu.
Moralo oa ho qetela ke ho sekisetsa ho tiisang hore, hantle-ntle, li-bearings tsa li-drill li ke ke tsa tsofala pele ho sebopeho sa ho seha (likotoana tsohle tsa tricone, rock bits, rolara rock drill bits li lokela ho senyeha ka ho lekana).Leha ho le joalo, cyclic loading e behiloeng holim'a li-bearings, maemong 'ohle, e tla qetella e hlolehile.Ha sena se etsahala ho leka-lekana le ho tsamaisana ha kopano ho senyeha 'me li-cones li notlela likoranteng.
