Kamoo ho Fihla ha Li-Tri-Cone Bits ho Fetohetseng Khoebo ea Merafo
Li-drill tsa li-tri-cone ke tse ling tsa litšepe tse khahlehang ka ho fetisisa 'marakeng kajeno. Ha se feela hore likotoana tsena tsa tri-cone li na le tšepe ea tungsten e tšoarellang, e nang le likhokahano tsa cobalt le nickel tse sebelisetsoang ho eketsa boima ba 3% ho isa ho 30%, li ntse li ka sebelisoa hape molemong oa ho cheka ha feela li le maemong a matle.
Lisebelisoa tsa ho cheka li-tri-cone li fetotse indasteri ea ho cheka le ea merafo. Pele ho lithulusi tsena tse thusang, ho phunngoa ho ne ho etsoa ka "tšepe ea letsoho," e neng e hloka ho tšoara chesele le hamore le ho otla lejoe khafetsa. Qetellong, lilemong tsa bo-1930, lienjiniere tse peli li ile tsa etsa mochine oa ho phunya tai-cone, o nang le likarolo tse tharo tsa cone. Patent ea sesebelisoa sena se secha, e ntlafalitsoeng ke Ralph Neuhaus, e ile ea tšoarella ho fihlela 1951, 'me ka mor'a moo ea fella ka hore lik'hamphani tse ling tse ngata li iketsetse likotoana tsa tsona.
Bophahamo ba likaroloana tsena tse tharo tse ncha tsa likhoune bo ile ba fetola tsela eo merafo le ho cheka li neng li etsoa ka eona 'me ea fetola liindasteri tse makholo ka mor'a moo.
Ha tšepe ea tungsten e sebelisoa bakeng sa likotoana tsena tsa tri-cone, molemo o mong o moholo oa sesebelisoa sena se secha o ile oa hlaha: ho hanyetsa mocheso. Kaha tungsten e na le sebaka se phahameng sa ho qhibiliha, likotoana tsa tungsten li ile tsa khona ho mamella mocheso o phahameng 'me li-driller li ile tsa khona ho cheka metheo e thata haholoanyane. Ntle le ho hanyetsa mocheso, tungsten e ka boela ea sebetsa ka potlako ho feta lisebelisoa tse ling, e lumella ho cheka ka lebelo le phahameng.
Ho se ho fetile matsatsi ao basebetsi ba merafong ba tlamehang ho fetola lichesele le ho phunya ka hamore ho phunyeletsa mohaho o thata. Ka lebaka la ho qaptjoa ha mochini oa ho phunya tai-cone, hona joale ho bonolo haholo ho phunya mafika a bonolo, a mahareng le a thata haholo.
Le hoja likotoana tsa tungsten carbide li le matla haholo 'me li ka tšoarella nako e telele ho feta hoo e batlang e le likotoana leha e le life tse ling, li ntse li senyeha ha nako e ntse e ea' me qetellong li tla hloka ho nkeloa sebaka. Ho bohlokoa hore le ka mohla u se ke ua lahla likotoana tsena tsa tungsten tri-cone, leha ho le joalo, hobane lik'hamphani tse nchafatsang tungsten li ka thabela ho fapanyetsana chelete bakeng sa li-carbide tsena tse matla.
Melemo ea Bit ea Tricone ka Kakaretso:
• Theknoloji e Lekiloeng ka Nako
• Ho ikamahanya le maemo
• Theko e tlaase
• Ts'ebetso ea Hard Rock
Molemo o moholo ka ho fetisisa oa li-drillers ka ho sebelisa li-tricone bits ke ntlha ea nako. Teko ea nako ea theknoloji ena e ruile molemo haholo 'bokhoni ba eona bo felletseng le litlolo tsa tlhahiso. Tlhokahalo e tsebahalang ea li-roller cone bits lilemong tse lekholo tse fetileng e lumelletse baetsi ba meralo ho ntlafatsa karolo e 'ngoe le e 'ngoe ea boro ena. Le hoja thekenoloji e ncha e ntse e le qalong ea ho iphetola ha lintho, trione e fihlile sehlohlolong sa ts'ebetso. Ho kopanya lintlafatso tse tsoelang pele ho lisebelisoa tsa mantlha tse kang Tungsten Carbide Inserts le Sealed Journal Bearings li ekelitse liphetho le ts'epo haholo mme li e etsa hore e ntse e le e 'ngoe ea lisebelisoa tse holimo' marakeng oa ho cheka.
Molemo o mong bakeng sa li-drillers tse sebelisang li-roller cone bit ke boiketlo ba ho tsamaisa. Ha ba tšoaroa maemong a thata, ba chekang ba na le likhetho tse ngata tse nang le lintlha tse kang Torque le Weight On Bit tseo ba neng ba ke ke ba li fuoa ha ba cheka ka PDC bit. Likotoana tsa Tricone li boetse li loketse mesebetsi e shebaneng le mefuta e fapaneng ea mafika a thata. Ho sisinyeha ha e 'ngoe le e 'ngoe ea lirolara tse tharo ho thusa ho pshatla lejoe, ho etsa hore le be bonolo haholoanyane bakeng sa tsoelo-pele.
Litsenyehelo tse akaretsang ke molemo o mong oa ho sebelisa likotoana tsena. Mesebetsing moo tekanyetso e sa lumelleng litšenyehelo tsa ho sebelisa PDC, tricone bit e ka ba qeto e phethahetseng ea moruo bakeng sa mosebetsi.
Re barekisi ba li-tricone bit. Haeba u batla ho ithuta haholoanyane ka li-tricone bits, ikopanye le rona kajeno!
