Hobaneng ha sintered tungsten carbide e le lisebelisoa tse hlokahalang bakeng sa li-valve?

Indasteri ea lik'hemik'hale tsa mashala, liphaephe tsa seretse le lintho tse ling tsa lipalangoang, karolo ea ho tiisa ea valve ha e felle feela ka ho ferekana ho thellang le ho roala ha likarolo tse thusang tse tiisang, empa hape le ho mamella tšusumetso e phahameng ea lebelo la duplex e tiileng ea khase. motsoako le mocheso o phahameng le boima bo phahameng, hammoho le ho benya le cavitation e bakoang ke mokelikeli o phahameng oa khatello, e leng se lebisang ho senyeha le ho mpefatsa ho hlōleha ha valve.Ka hona, tlas'a maemo a thata a ho sebetsa a kang lipalangoang tsa phofo, ho hanyetsa ho roala ke letšoao la bohlokoa haholo la tlhahlobo ea ts'ebetso ea valve.

Re khetha integral sintered tungsten carbide e le thepaho etsa valve, e se nang matla a phahameng feela, empa hape e na le qetello e phahameng ea holim'a metsi, ha e sebelisoa lisebelisoa tse ling, coefficient ea friction e nyenyane ho feta tšepe, e ka fokotsang haholo ho fereka ha sebaka sa ho kopana le ho fokotsa ka katleho torque e sebetsang.

Integral sintered tungsten carbide e entsoe ka ho futhumatsa motsoako oa tungsten le carbon ka mocheso o phahameng, boholo ba tungsten carbide e na le boima bo phahameng.ho joalo ha ho bonolo ho bola ka mocheso o phahameng, lehapee na le khanyetso e ntle ea oxidation.

Ka har'a valve ea mashala, valve disc le setulo sa valve li entsoe ka integral sintered tungsten carbide ho etsa para e tiisang, 'me valve e na le melemo e latelang e totobetseng.:

1,Boima bo phahameng.hardness> 80HRC, e ka mamellang khoholeho e phahameng ka potlako ea multiphase particle media e kang slurry ea metsi a mashala, mashala a pulverized, silica fume, joalo-joalo.

2,Ho hanyetsa mocheso o phahameng.E ka sebetsa ho750°C mocheso o phahameng ka nako e telele, 'me matla a eona, ho khomarela le ho atolosoa ha mocheso ha ho felle ka mocheso, o kopanang ka botlalo le maemo a phahameng a mocheso a kang indasteri ea lik'hemik'hale tsa mashala..

3,Ho hanyetsa khatello e phahameng.Matla a ho robeha a pota-potileng a sintered tungsten carbide ka kakaretsoka khonafihla 4000MPa, e leng makhetlo a fetang 10of tšepe e tloaelehileng.

4,Corrosion-resistance.Carbide e entsoeng ka sintered ka kakaretso e tsitsitse ka lik'hemik'hale, ha e qhibilihe ka metsing le haeba e futhumetse, 'me ha e sebelisane le hydrochloric acid le sulfuric acid.

5Abrasion resistance.Litšobotsi tsa boima bo phahameng le botsitso bo phahameng ba carbide e kentsoeng ea sintered sintered e netefatsa ts'ebetso e ntle ea anti-wear ea "sub-material" ea tiiso..

6Erosion Resistance.

Ka kakaretso, motsoako oa sintered sintered tungsten carbide cemented carbide e na le matla a phahameng, boima bo phahameng, ntlha e qhibilihisang haholo, botsitso bo phahameng, coefficient e tlase ea likhohlano, ho hanyetsa ho roala, ho hanyetsa khoholeho ea mobu le cavitation, ho hanyetsa kutu, le ho etsoa ha litiiso tsa li-valve tse sa sebetseng. maemo a thata a ho sebetsa a ka ntlafatsa haholo ts'ebetso ea valve, ho atolosa sebaka sa tšebeliso ea valve, le ho lelefatsa bophelo ba mosebetsi oa valve.

Zhuzhou Chuangrui Cemented Carbide Co., Ltd. e fana ka lisebelisoa tsa boleng bo holimo tse sa sebetseng le theknoloji e thatafatsang holim'a li-valve ho fana ka tharollo bakeng sa maemo a thata a ts'ebetso ea indasteri ea lik'hemik'hale tsa mashala..
