Tungsten Carbide bearings: Tharollo ea ho qetela bakeng sa Likopo tse Phahameng tsa Ts'ebetso ea Indasteri

Sebakeng sa mechine ea indasteri, li-bearings li sebeletsa e lemokokotlots'ebetso e boreleli, empa ha se li-bearings tsohle tse entsoeng ka ho lekana.Lihlahisoa tsa tungsten carbideli hlahile e le papali-papali, nyehelonako e telele le tshebetso e ke keng ya lekanngoae fetisang lisebelisoa tsa setso joalo ka tšepe kapa ceramic. E entsoe ka tungsten carbide - e leng motsoako oa tungsten le carbon e tummeng ka ho thatafala ha eona (ea bobeli ho daemane) le ho hanyetsa ho roala - li-bearings tsena li etselitsoe hore li atlehemaemo a boima haholo,li etsa hore e be tsa bohlokoa ho liindasteri tsa bohlokoa.

E 'ngoe ea melemo e tsotehang ea li-bearings tsa tungsten carbide ke tsonaboima bo ikhethang, e lekantsoeng ho 90-95 HRA (Rockwell Hardness Scale). Thepa ena e ba nolofalletsa homamella meroalo e boima, lebelo le phahameng, le likaroloana tse hlabangntle le ho holofala kapa ho putlama, e leng tšobotsi ea bohlokoa bakeng sa makala a kang merafo, oli le khase, le tlhahiso. Ka mohlala, ts'ebetsong ea merafo, li-tungsten carbide bearings power conveyor systems le li-crusher, tse mamellang likhohlano tse sa khaotseng tse tsoang ho liminerale le lerōle le bohale. Ka indasteri ea oli le khase, li ipabola ka lisebelisoa tsa ho cheka likoti, moo li hanang ho bola ho tsoa ho metsi a acidic le ho boloka botšepehi tlas'a khatello e feteletseng (ho fihlela ho 10,000 psi) le mocheso (ho feta 300 ° C). Ho fapana le li-bearings tsa tšepe, tseo hangata li hlokang ho nkeloa sebaka khafetsa ka lebaka la ho koaleha, mefuta e fapaneng ea tungsten carbide e ithorisa ka nako ea bophelo ho fihla ho makhetlo a 10, e fokotsa haholo litšenyehelo tsa tlhokomelo le nako ea ho theoha ha likhoebo.

Molemo o mong oa bohlokoa ke oa bonakhanyetso e phahameng ea kutu. Li-bearings tsa khale tsa tšepe li na le mafome le ho senyeha ha li pepesehile mongobo, lik'hemik'hale, kapa metsi a letsoai, empa tlhaho e sa sebetseng ea tungsten carbide e e sireletsa tšenyo e joalo. Sena se li etsa hore e be tse loketseng bakeng sa lisebelisoa tsa leoatleng, tse kang li-propeller shafts le lipompo tse ka tlas'a metsi, hammoho le lifeme tsa ho lokisa lik'hemik'hale moo li-bearings li kopanang le metsoako e senyang. Ho feta moo, khohlano ea bona e tlase e tiisa hore ho potoloha ha bona hantle esita le ka lebelo le holimo, ho fokotsa tahlehelo ea matla le ho ntlafatsa ts'ebetso ea mochini - ntho ea bohlokoa bakeng sa liindasteri tse lekang ho fokotsa likhahla tsa khabone le litšenyehelo tsa ts'ebetso.

Ha li-bearings tsa tungsten carbide li fana ka ts'ebetso e tsotehang, ea bonamoralo le ho kenyahloka ho nepahala. Hangata bahlahisi ba li etsa hore li lumellane le lits'ebetso tse ikhethileng, ho lokisa lintlha tse kang ho kolobisoa, ho roala (mohlala, k'habone e kang daemane bakeng sa lubricity e eketsehileng), le mofuta oa sealant ho ntlafatsa ts'ebetso. Tlhokomelo e nepahetseng, joalo ka ho tlotsa khafetsa ka mafura a mocheso o phahameng, ho eketsa bophelo ba bona ba ts'ebeletso.

Ha liindasteri li ntse li tsoela pele ho sutumelletsa meeli ea lebelo, mojaro, le botsitso ba tikoloho, li-tungsten carbide bearings li se li le malala a laotsoe ho bapala karolo ea bohlokoa le ho feta. Ho tloha ho liroboto tse tsoetseng pele tsa tlhahiso ho ea ho lisebelisoa tsa matla tse nchafalitsoeng joalo ka lijenereithara tsa turbine ea moea, bokhoni ba tsona ba ho kopanya ho thatafala, ho hanyetsa kutu, le bophelo bo bolelele bo etsa hore e be khetho ea pele bakeng sa baenjiniere ba batlang litharollo tse tšepahalang, tse sebetsang hantle. Lefatšeng leo ho lona ho sebetsa hantle le ho tšoarella ha mochini ho amang tlhahiso le phaello ka kotloloho, li-bearings tsa tungsten carbide li eme e le bopaki ba hore nalisebelisoa tse ncha li ka fetola ts'ebetso ea indasteri.
