Thepa ea Lifahleho tsa Carbon Seal
Carbon ke ntho e sebelisoang hangata bakeng salifahleho tsa tiiso ea mochinika lebaka la thepa ea eona e ikhethang. E fana ka litšobotsi tse ntle tsa ho tlotsa, tse thusang ho fokotsa likhohlano le ho roala pakeng tsa lifahleho tsa tiiso nakong ea ts'ebetso. Carbon e boetse e bonts'a conductivity e ntle ea mocheso, e e lumellang hore e felise mocheso hantle le ho thibela mocheso o feteletseng ho sehokelo sa tiiso.
Molemo o mong oa lifahleho tsa carbon seal ke bokhoni ba bona ba ho lumellana le ho se phethahale ho fokolang kapa ho se lumellane ha bona sebakeng sa ho nyalana. Ho ikamahanya le maemo hona ho tiisa tiiso e tiileng le ho fokotsa ho lutla. Carbon e boetse e hanana le mefuta e mengata ea lik'hemik'hale, e etsa hore e loketse ho sebelisoa lits'ebetsong tse fapaneng tsa indasteri.
Thepa ea Silicon Carbide Seal Faces
Silicon carbide (SiC) ke khetho e 'ngoe e tsebahalang bakeng sa lifahleho tse tiisitsoeng tsa mochini ka lebaka la ho thatafala ha eona le ho hanyetsa ho roala. Lifahleho tsa SiC seal li ka mamella maemo a thata a ts'ebetso, ho kenyelletsa likhatello tse phahameng, mocheso le mecha ea litaba e senyang. Thepa e phahameng ea mocheso e thusa ho qhala mocheso, ho thibela ho sotha ha mocheso le ho boloka botšepehi ba tiiso.
Lifahleho tsa SiC seal li boetse li fana ka khanyetso e ntle ea lik'hemik'hale, e li etsang hore li tšoanelehe ho sebelisoa libakeng tse senyang. Qetello e boreleli ea SiC e fokotsa likhohlano le ho roala, e lelefatsa bophelo ba tiiso ea mochini. Ntle le moo, modulus e phahameng ea SiC ea elasticity e fana ka botsitso ba sebopeho, ho netefatsa hore lifahleho tsa tiiso li lula li bataletse ebile li bapile nakong ea ts'ebetso.
Phapang lipakeng tsa Carbon le Silicon Carbide
Sebopeho le Sebopeho
Litiiso tse entsoeng ka carbon li entsoe ka graphite, mofuta oa carbon o tsejoang ka thepa ea eona ea ho itlotsa le ho hanyetsa mocheso le tlhaselo ea lik'hemik'hale. Hangata graphite e kenngoa ka resin kapa tšepe ho ntlafatsa thepa ea eona ea mochine.
Silicon carbide (SiC) ke thepa ea ceramic e thata, e manganga e entsoeng ka silicon le carbon. E na le sebopeho sa kristale se tlatsetsang ho thatafala ha eona, conductivity ea mocheso, le botsitso ba lik'hemik'hale.
Ho thatafala le ho Rua Khanyetso
Silicon carbide e thata haholo ho feta carbon, e nang le boima ba Mohs ba 9-9.5 ha bo bapisoa le 1-2 bakeng sa graphite. Ho thatafala hona ho phahameng ho etsa hore SiC e se ke ea hlola e e-ba le moaparo o hlabang, esita le lits'ebetsong tse boima tse nang le mecha ea litaba e senyang.
Litiiso tsa carbon, ha li ntse li le bonolo, li ntse li fana ka khanyetso e ntle ea ho apara libakeng tse sa senyeheng. Mokhoa oa ho itlotsa oa graphite o thusa ho fokotsa khohlano le ho roala pakeng tsa lifahleho tsa tiiso.
Ho hanyetsa Mocheso
Ka bobeli carbon le silicon carbide li na le thepa e ntle haholo ea mocheso o phahameng. Litiiso tsa carbon li ka sebetsa ka mocheso ho fihlela ho 350 ° C (662 ° F), ha li-silicon carbide li ka mamella mocheso o phahameng le ho feta, hangata o feta 500 ° C (932 ° F).
Thermal conductivity ea silicon carbide e phahame ho feta ea carbon, e lumellang litiiso tsa SiC ho qhala mocheso ka katleho le ho boloka mocheso o tlaase oa ts'ebetso sebakeng sa ho tiisa.
Khanyetso ea Lik'hemik'hale
Silicon carbide ha e kenelle ka lik'hemik'hale 'me ha e khone ho hlaseloa ke li-acids tse ngata, li-bases le li-solvents. Ke khetho e ntle haholo bakeng sa ho tiisa mecha ea litaba e senyang haholo kapa e mabifi.
Carbon e boetse e fana ka khanyetso e ntle ea lik'hemik'hale, haholo-holo ho metsoako ea lintho tse phelang le li-acids le li-bases tse se nang oxidizing. Leha ho le joalo, e kanna ea se tšoanelehe haholo bakeng sa tikoloho e nang le oxidizing e matla kapa lits'ebetso tse nang le media e phahameng ea pH.
Litšenyehelo le ho ba Teng
Litiiso tsa mochini oa carbon hangata li theko e tlase ho feta litiiso tsa silicon carbide ka lebaka la theko e tlase ea lisebelisoa tse tala le lits'ebetso tse bonolo tsa tlhahiso. Litiiso tsa carbon li fumaneha hohle 'me li ka hlahisoa ka mefuta e fapaneng ea limaraka le litlhophiso.
Litiiso tsa Silicon carbide li khethehile haholoanyane 'me hangata li tla ka theko e phahameng. Ho hlahisa likarolo tsa boleng bo phahameng ba SiC ho hloka mekhoa e tsoetseng pele ea tlhahiso le taolo e tiileng ea boleng, e tlatsetsang ho theko e eketsehileng.
Nako ea ho Sebelisa Carbon Seal
Lifahleho tsa carbon seal li loketse lits'ebetso tse kenyelletsang likhatello tse tlase ho isa ho tse itekanetseng le mocheso. Hangata li sebelisoa lipompong tsa metsi, li-mixer, le li-agitator moo mecha ea phatlalatso ea ho tiisa e sa senyeheng haholo kapa e senyang. Litiiso tsa carbon li boetse li loketse ho tiisa metsi a nang le thepa e fokolang ea ho tlotsa, kaha thepa ea carbon ka boeona e fana ka lubrication.
Lits'ebetsong tse nang le lipotoloho tsa ho emisa khafetsa kapa moo shaft e kopanang le motsamao oa axial, lifahleho tsa carbon seal li ka amohela maemo ana ka lebaka la thepa ea tsona ea ho itlotsa le bokhoni ba ho ikamahanya le liphoso tse nyane sebakeng sa ho nyalana.
Nako ea ho Sebelisa Silicon Carbide Seal
Lifahleho tsa Silicon carbide seal li ratoa lits'ebetsong tse kenyelletsang likhatello tse phahameng, mocheso, le mecha ea litaba e senyang kapa e senyang. Hangata li sebelisoa lits'ebetsong tse boima tsa indasteri, joalo ka tlhahiso ea oli le khase, ts'ebetso ea lik'hemik'hale le tlhahiso ea matla.
Litiiso tsa SiC li boetse li loketse ho tiisa metsi a hloekileng haholo, kaha ha a silafatse mecha ea phatlalatso e tiisitsoeng. Lits'ebetsong moo mecha ea phatlalatso ea ho tiisa e nang le thepa e fokolang ea ho tlotsa, SiC's coefficient e tlase ea likhohlano le ho hanyetsa ho roala e etsa khetho e ntle haholo.
Ha tiiso ea mochini e ba le maemo a feto-fetohang a mocheso khafetsa kapa ho tsukutloa ha mocheso, SiC's conductivity e phahameng ea mocheso le botsitso ba sebopeho li thusa ho boloka ts'ebetso ea tiiso le bophelo bo bolelele. Ho feta moo, litiiso tsa SiC li loketse lits'ebetso tse hlokang bophelo bo bolelele ba ts'ebeletso le tlhokomelo e nyane ka lebaka la ho tšoarella ha tsona ka mokhoa o ikhethang le ho hana ho roala.

Ke thepa efe ea mochini ea tiiso e sebelisoang haholo?
Carbon e sebelisoa hangata ho litiiso tsa mochini ka lebaka la theko ea eona e tlase le ts'ebetso e lekaneng lits'ebetsong tse ngata.
Na litiiso tsa carbon le silicon carbide li ka sebelisoa ka ho fapanyetsana?
Maemong a mang, ho joalo, empa ho ipapisitse le litlhoko tse ikhethileng tsa kopo, joalo ka mocheso, khatello le ho lumellana ha mokelikeli.
Ha re phethela
Ha u khetha pakeng tsa litiiso tsa mochini oa carbon le silicon carbide, nahana ka litlhoko tse khethehileng tsa kopo. Silicon carbide e fana ka boima bo phahameng le ho hanyetsa lik'hemik'hale, ha carbon e fana ka bokhoni bo betere ba ho matha.
