Tšebeliso ea Titanium Alloy indastering ea li-valve

Titanium alloy e na le melemo e mengata e kang ho teteana ho tlase, matla a phahameng, ho hanyetsa kutu, mocheso o phahameng le ho hanyetsa mocheso o tlase, 'me e ka sebelisoa haholo mafapheng a mangata a kang petroleum, indasteri ea lik'hemik'hale, tikoloho ea leoatle, biomedicine, sefofane, indasteri ea likoloi le likepe. . Cast titanium alloy e fumanoa ka ho lahlela motsoako oa titanium ka sebopeho se lakatsehang, moo motsoako oa ZTC4 (Ti-6Al-4V) o sebelisoang ka ho fetisisa, o nang le ts'ebetso e tsitsitseng ea ts'ebetso, matla a matle le boima ba ho robeha (ka tlase ho 350 ℃).

E le karolo e ka sehloohong ea taolo ea libaka tse sa tšoaneng tse khethehileng le mekhoa e khethehileng ea ho tsamaisa lipeipi tsa metsi, li-valve li fetohile karolo ea bohlokoa ea lisebelisoa tse ngata tsa tlhahiso, 'me ho ka boleloa hore indasteri leha e le efe e ke ke ea etsa ntle le li-valve. Ka lebaka la litlhoko tse fapaneng tsa tikoloho, mocheso le mahareng mafapheng a fapaneng, khetho ea thepa ea li-valve e bohlokoa haholo ebile e bohlokoa haholo. Li-valve tse thehiloeng holim'a li-alloys tsa titanium le li-alloys tse entsoeng ka titanium li na le menyetla e pharaletseng tšimong ea li-valve ka lebaka la ho hanyetsa ha tsona ho matla ha kutu, ts'ebetso e phahameng le e tlase ea mocheso, le matla a phahameng.

Ha ho bapisoa le li-alloys tsa koporo tse neng li sebelisoa pele, tšepe, joalo-joalo, liteko tse latelang tsa drainage le tsona li bontšitse hore tšebeliso ea li-alloys tse entsoeng ka titanium e na le ts'epo e phahameng likarolong tse ngata tse kang matla a sebopeho le ho hanyetsa kutu, 'me bophelo ba tšebeletso bo ekelitsoe haholo. lilemo tsa pele tsa 2-5 ho feta habeli, tse hohetseng tlhokomelo e atileng ho tsoa ho motho e mong le e mong. Li-valve tse tharo tsa serurubele tse fanoeng ke Setsi sa Patlisiso sa China Shipbuilding 725 se Luoyang, Chaena bakeng sa mohlala o itseng oa sekepe ke phetoho ea moralo o fetileng oa khetho le moralo, o sebelisa Ti80 le lisebelisoa tse ling e le 'mele o ka sehloohong, o lelefatsang bophelo ba tšebeletso. valve ho fihlela lilemo tse fetang 25, ho ntlafatsa ts'epo le ts'ebetso ea ts'ebeliso ea lihlahisoa tsa valve, le ho tlatsa lekhalo la tekheniki naheng ea China.

- Sepakapaka
Lefapheng la aerospace, li-alloys tse entsoeng ka titanium le tsona li sebetsa hantle, ka lebaka la matla a tsona a ho hanyetsa mocheso le matla. E ne e boetse e le lilemong tsa bo-1960 moo American Airlines e ileng ea qala ho leka ho hlahisa titanium. Ka mor'a nako ea lipatlisiso, lihlahisoa tsa titanium alloy li 'nile tsa sebelisoa ka molao lifofaneng ho tloha ka 1972 (Boeing 757, 767, le 777, joalo-joalo). Ha se feela palo e kholo ea li-static structure titanium alloy castings e sebelisitsoeng, empa hape e sebelisitsoe maemong a mahlonoko, joalo ka taolo ea li-valve lits'ebetsong tsa bohlokoa tsa liphaephe. Li-valve tse sebelisoang ka tloaelo li kenyelletsa li-valve tsa polokeho, li-valve tsa ho hlahloba, joalo-joalo, tse fokolitseng litšenyehelo tsa ho etsa lifofane le ho eketsa polokeho le ts'epo, Ho sa le joalo, ka lebaka la boima bo batlang bo le bonyenyane le boima ba alloy ea titanium ha e bapisoa le li-alloys tse ling, tse ka bang 60% feela ea tšepe e tšoanang ea matla, ts'ebeliso ea eona e atileng e ka khothaletsa lifofane ho tsamaea butle ho ea matla a phahameng le tataiso e bobebe. Hajoale, li-valve tsa sepakapaka li sebelisoa haholo lits'ebetsong tse ngata tsa taolo tse kang pneumatic, hydraulic, fuel, le lubrication, 'me li loketse haholoanyane tikolohong e hanyetsanang le kutu le mocheso o phahameng oa tikoloho. Ke e 'ngoe ea likarolo tsa bohlokoa tsa likoloi tsa sepakapaka, lienjineri le mafapha a mang. Hangata li-valve tsa setso li hloka ho nchafatsoa ka mekhahlelo, 'me li ka 'na tsa se ke tsa finyella tlhokahalo. Ka nako e ts'oanang, ka keketseho e potlakileng ea 'maraka oa li-valve tsa aerospace, li-valve tsa titanium le tsona li nka karolo e ntseng e eketseha ka lebaka la ts'ebetso ea tsona e holimo.

- Indasteri ea lik'hemik'hale
Li-valve tsa lik'hemik'hale hangata li sebelisoa libakeng tse thata joalo ka mocheso o phahameng, khatello e phahameng, ho hanyetsa kutu, le phapang e kholo ea khatello. Ka hona, khetho ea lisebelisoa tse nepahetseng ke ea bohlokoa bakeng sa ts'ebeliso ea indasteri ea lik'hemik'hale tsa valve. Qalong, tšepe ea carbon, tšepe e sa hloekang, le lisebelisoa tse ling li khethoa haholo-holo, 'me ho ka etsahala hore ho be le kutu ka mor'a ho sebelisoa, ho hloka hore ho nkeloe sebaka le tlhokomelo. Ka nts'etsopele e tsoelang pele ea theknoloji ea alloy ea titanium le ts'ebetso ea eona e holimo e ntse e sibolloa, li-valve tsa titanium le tsona li hlahile mahlong a batho. Ho nka karolo ea tlhahiso ea purified terephthalic acid (PTA) indastering ea fiber ea lik'hemik'hale e le mohlala, sebaka sa ho sebetsa ke haholo-holo acetic acid le hydrobromic acid, e nang le ho bola ho matla. Hoo e ka bang li-valve tsa 8000, ho kenyelletsa le li-valve tsa globe le li-valve tsa bolo, li hloka ho sebelisoa, ka mefuta e sa tšoaneng le palo e kholo. Ka hona, li-valve tsa titanium li fetohile khetho e ntle, ho eketsa ts'episo le polokeho ea ts'ebeliso. Ka kakaretso, ka lebaka la ho bola ha urea, li-valve tse tsoang kantle le ho kena ha urea synthesis tower li ka fihlela bophelo ba ts'ebeletso ea selemo se le seng mme li se li fihletse litlhoko tsa ts'ebeliso. Likhoebo tse kang Shanxi Lvliang Fertilizer Plant, Shandong Tengzhou Fertilizer Plant, le Henan Lingbao Fertilizer Plant li entse liteko tse ngata 'me qetellong li khethile li-valve tsa titanium high-pressure check valves H72WA-220ROO-50, H43WA-220ROO-50, 65, 80, li-valve tsa ho emisa BJ45WA-25R-100, 125, joalo-joalo bakeng sa ho kenngoa ha litora tsa urea synthesis, tse nang le bophelo ba tšebeletso ea lilemo tse fetang 2, tse bontšang khanyetso e ntle ea kutu [9], ho fokotsa makhetlo le litšenyehelo tsa ho fetola li-valve.

Ts'ebeliso ea alloy ea cast titanium 'marakeng oa li-valve ha e felle feela liindastering tse boletsoeng ka holimo, empa ho na le nts'etsopele e ntle likarolong tse ling. Mohlala, motsoako o mocha oa titanium oa Ti-33.5Al-1Nb-0.5Cr-0.5Si o ntlafalitsoeng Japane o na le melemo e mengata joalo ka letsoalo le tlase, matla a phahameng a ho qhekella, le ho hanyetsa ho apara hantle. Ha e sebelisoa ka har'a valve e ka morao ea enjine ea likoloi, e ka ntlafatsa ts'ebetso ea ts'ireletso ea enjene le ho lelefatsa bophelo ba eona ba ts'ebeletso.

- Liindasteri tse ling
Ha ho bapisoa le ts'ebeliso ea li-alloys tsa cast titanium indastering ea li-valve, lits'ebetso tse ling tsa li-alloys tsa cast titanium li pharalletse haholo. Li-alloys tsa titanium le titanium li na le khanyetso e ntle ea kutu, e bohlokoa haholo bakeng sa liindasteri tse nang le litlhoko tse senyang joalo ka indasteri ea petrochemical. Liindastering tsena, lisebelisoa tse ngata tse kholo tse hlokang tlhahiso ea indasteri joalo ka lipompo tsa volumetric, li-heaters tsa mocheso, li-compressor le li-reactors li tla sebelisa li-titanium tse thibelang kutu, tse nang le tlhoko e kholo ea 'maraka. Lefapheng la bongaka, ka lebaka la hore titanium ke tšepe e sireletsehileng e tsebahalang lefatšeng ka bophara, e seng chefo, le tšepe e matla, lisebelisoa tse ngata tsa thuso ea bongaka, li-prostheses tsa batho, le tse ling li entsoe ka li-alloys tse entsoeng ka titanium. Haholo-holo meriana ea meno, hoo e batlang e le lisebelisoa tsohle tsa meno tse lekiloeng li entsoe ka titanium e hloekileng ea indasteri le motsoako oa Ti-6Al-4V, o nang le biocompatibility e ntle, thepa ea mochine le ho hanyetsa ho bola. Ka lehlakoreng le leng, ka lebaka la melemo ea sekhahla se tlase le ts'ebetso e ntle ea li-alloys tsa titanium le titanium, li sebelisoa haholo lisebelisoa tse ngata tsa lipapali tse kang lihlopha tsa kolofo, lihlooho tsa bolo, lirakete tsa tennis, li-racket tsa badminton le lisebelisoa tsa ho tšoasa litlhapi. Lihlahisoa tse entsoeng ka tsona li bobebe, li na le tiiso ea boleng, 'me li tumme haholo har'a sechaba. Mohlala, alloy e ncha ea titanium ea SP-700 e ntlafalitsoeng ke Japan Steel Pipe Company (N104) e sebelisoa e le thepa e holimo bakeng sa Taylor brand 300 series, e rekisoang haholo 'marakeng oa kolofo oa lefatše. Ho tloha bofelong ba lekholo la bo20 la lilemo, li-alloys tsa "titanium" li thehile indasteri butle butle le ho hola masimong a kang petrochemical, aerospace, biomedical, indasteri ea likoloi, le lipapali le boikhathollo, ho tloha tlhahlobong ea pele ho ea ho nts'etsopele le nts'etsopele e matla ea hajoale.
