Kugwiritsa Ntchito Titanium Alloy M'makampani a Valve

Titaniyamu aloyi ali ndi zabwino zambiri monga otsika kachulukidwe, mphamvu mkulu, kukana dzimbiri, kutentha kwambiri ndi kutsika kutentha kukana, ndipo angagwiritsidwe ntchito kwambiri m'madera ambiri monga mafuta, makampani mankhwala, chilengedwe m'madzi, biomedicine, Azamlengalenga, makampani magalimoto, ndi zombo. . Cast titaniyamu aloyi anapezedwa poponya titaniyamu aloyi mu mawonekedwe ankafuna, pakati pa ZTC4 (Ti-6Al-4V) aloyi ndi ambiri ntchito, ndi khola ndondomeko ntchito, mphamvu zabwino ndi fracture kulimba (pansi pa 350 ℃).

Monga chigawo chachikulu chowongolera madera osiyanasiyana apadera komanso machitidwe apadera oyendetsa mapaipi amadzimadzi, ma valve akhala gawo lofunikira la zida zambiri popanga, ndipo tinganene kuti makampani aliwonse sangathe kuchita popanda ma valve. Chifukwa cha zosiyana zachilengedwe, kutentha, ndi zofunikira zapakati m'madera osiyanasiyana, kusankha zinthu za valve ndizofunikira kwambiri komanso ndizofunikira kwambiri. Mavavu otengera ma aloyi a titaniyamu ndi ma aloyi opangidwa ndi titaniyamu ali ndi chiyembekezo chokulirapo pantchito ya mavavu chifukwa cha kukana kwawo kwa dzimbiri, kutentha kwambiri komanso kutsika, komanso mphamvu zambiri.

Mapulogalamu

- Marine
Malo ogwirira ntchito a mapaipi amadzi a m'nyanja ndi ovuta kwambiri, ndipo machitidwe a mavavu apanyanja amakhudza mwachindunji chitetezo ndi machitidwe onse a mapaipi. Kumayambiriro kwa zaka za m'ma 1960, dziko la Russia linayamba kufufuza za ma aloyi a titaniyamu a zombo zapamadzi ndipo kenako anawapanga kuti azigwiritsa ntchito panyanja. ndi ntchito zambiri; Panthawi imodzimodziyo, ma valve a titaniyamu akhala akugwiritsidwa ntchito m'mapaipi amtundu wamba. Poyerekeza ndi aloyi mkuwa kale ntchito, zitsulo, etc., wotsatira ngalande mayesero asonyezanso kuti ntchito kuponyedwa titaniyamu aloyi ali ndi kudalirika mkulu m'mbali zambiri monga mphamvu structural ndi dzimbiri kukana, ndi moyo utumiki wakhala anawonjezera, kuchokera zaka zoyambirira za 2-5 mpaka kuwirikiza kawiri, zomwe zakopa chidwi cha aliyense. The atatu eccentric gulugufe valavu woperekedwa ndi China Shipbuilding 725 Research Institute ku Luoyang, China kwa chitsanzo china cha zombo ndi kusintha m'mbuyomu kusankha zinthu ndi kapangidwe chiwembu, ntchito Ti80 ndi zipangizo zina monga thupi lalikulu, kukulitsa moyo utumiki wa valavu kwa zaka zoposa 25, kuwongolera kudalirika ndi kuchitapo kanthu kwa ntchito zama valve, ndikudzaza kusiyana kwaukadaulo ku China.

- Zamlengalenga
Pankhani yazamlengalenga, zotayira za titaniyamu zimagwiranso ntchito bwino, chifukwa cha kukana kwawo kutentha komanso mphamvu. Zinalinso m'zaka za m'ma 1960 kuti American Airlines idayesa koyamba kuponya titaniyamu. Pambuyo pa kafukufuku, titaniyamu alloy castings akhala akugwiritsidwa ntchito mwalamulo mu ndege kuyambira 1972 (Boeing 757, 767, ndi 777, etc.). Osangokhala ndi ma static structure titanium alloy castings omwe agwiritsidwa ntchito, koma amagwiritsidwanso ntchito m'malo ovuta, monga kuwongolera ma valve pamapaipi ofunikira. Ma valve omwe amagwiritsidwa ntchito kawirikawiri amaphatikizapo ma valve otetezera, ma valve owonetsetsa, ndi zina zotero, zomwe zachepetsa ndalama zopangira ndege ndikuwonjezera chitetezo ndi kudalirika, Pakalipano, chifukwa cha kachulukidwe kakang'ono ndi kulemera kwa titaniyamu poyerekeza ndi ma alloys ena, omwe ali pafupifupi 60% ya chitsulo chofanana champhamvu, kugwiritsa ntchito kwake kofala kumatha kulimbikitsa ndege kuti zisunthike pang'onopang'ono kumphamvu yayikulu komanso njira yopepuka. Pakalipano, mavavu amlengalenga amagwiritsidwa ntchito kwambiri m'machitidwe ambiri olamulira monga pneumatic, hydraulic, mafuta, ndi mafuta, ndipo ndi abwino kwambiri m'madera omwe ali ndi kukana kwa dzimbiri komanso kutentha kwakukulu kwa chilengedwe. Ndi chimodzi mwazinthu zofunika kwambiri zamagalimoto apamlengalenga, injini, ndi madipatimenti ena. Mavavu achikhalidwe nthawi zambiri amafunikira kusinthidwa pang'onopang'ono, ndipo mwina sangakwaniritse zofunikira. Nthawi yomweyo, ndikukula kwachangu kwa msika wamavavu amlengalenga, ma valve a titaniyamu akutenganso gawo lochulukirapo chifukwa chakuchita bwino kwambiri.

- Chemical Viwanda
Ma valve a Chemical nthawi zambiri amagwiritsidwa ntchito m'malo ovuta monga kutentha kwambiri, kuthamanga kwambiri, kukana dzimbiri, komanso kusiyana kwakukulu kwapanikizidwe. Chifukwa chake, kusankha zida zoyenera ndikofunikira pakugwiritsa ntchito makina amagetsi a valve. Kumayambiriro koyambirira, zitsulo za carbon, zitsulo zosapanga dzimbiri, ndi zipangizo zina zimasankhidwa makamaka, ndipo dzimbiri zimatha kuchitika pambuyo pa ntchito, zomwe zimafuna kusinthidwa ndi kukonzanso. Ndi chitukuko chosalekeza cha ukadaulo wopangira titaniyamu aloyi komanso magwiridwe ake apamwamba pang'onopang'ono akudziwika, mavavu a titaniyamu awonekeranso m'maso mwa anthu. Kutengera gawo lopanga la oyeretsedwa terephthalic acid (PTA) mumakampani opanga mankhwala monga mwachitsanzo, sing'anga yogwirira ntchito imakhala ndi asidi acetic ndi hydrobromic acid, yomwe ili ndi corrosiveness yamphamvu. Pafupifupi ma valve 8000, kuphatikizapo ma valve a globe ndi ma valve a mpira, ayenera kugwiritsidwa ntchito, ndi mitundu yosiyanasiyana komanso chiwerengero chachikulu. Chifukwa chake, mavavu a titaniyamu akhala chisankho chabwino, ndikuwonjezera kudalirika komanso chitetezo chogwiritsa ntchito. Nthawi zambiri, chifukwa cha kuwonongeka kwa urea, mavavu omwe amatuluka ndi polowera munsanja ya urea synthesis amatha kukwaniritsa moyo wautumiki wa chaka chimodzi ndipo afika kale pamagwiritsidwe ntchito. Mabizinesi monga Shanxi Lvliang Fertilizer Plant, Shandong Tengzhou Fertilizer Plant, ndi Henan Lingbao Fertilizer Plant ayesa kangapo ndipo pamapeto pake adasankha ma valve a titaniyamu othamanga kwambiri H72WA-220ROO-50, H43WA-220ROO-50, 65, 80, ndi kutchinjiriza, ma valve oyimitsa BJ45WA-25R-100, 125, ndi zina zotero pofuna kuitanitsa nsanja za urea synthesis, ndi moyo wautumiki wa zaka zoposa 2, kusonyeza kukana kwa dzimbiri kwabwino [9], kuchepetsa mafupipafupi ndi mtengo wa kusintha kwa valve.

Kugwiritsa ntchito aloyi ya titaniyamu pamsika wa ma valve sikungokhala m'mafakitale omwe tawatchulawa, koma pali chitukuko chabwino pazinthu zina. Mwachitsanzo, aloyi watsopano wa titaniyamu wa Ti-33.5Al-1Nb-0.5Cr-0.5Si wopangidwa ku Japan ali ndi zabwino zambiri monga kusachulukira kochepa, mphamvu zokwawa kwambiri, komanso kukana kuvala bwino. Ikagwiritsidwa ntchito mu valavu yakumbuyo ya injini zamagalimoto, imatha kupititsa patsogolo chitetezo cha injini ndikuwonjezera moyo wake wautumiki.

- Makampani Ena
Poyerekeza ndi kugwiritsa ntchito ma aloyi a titaniyamu m'makampani opanga ma valve, ntchito zina zopangira titaniyamu ndizochulukirapo. Titaniyamu ndi titaniyamu alloys ali ndi bwino kukana dzimbiri, amene ali ofunika kwambiri kwa mafakitale ndi zofunika dzimbiri monga mafakitale petrochemical. M'mafakitalewa, zida zazikulu zambiri zomwe zimafunikira kupanga mafakitale monga mapampu a volumetric, zosinthira kutentha, ma compressor, ndi ma reactors adzagwiritsa ntchito ma titaniyamu osachita dzimbiri, omwe amafunikira kwambiri msika. M'munda wa zamankhwala, chifukwa titaniyamu kukhala chitsulo chodziwika bwino padziko lonse lapansi, chosakhala ndi poizoni, komanso chitsulo cholemera kwambiri, zida zambiri zothandizira zamankhwala, ma prostheses amunthu, ndi zina zimapangidwa ndi ma aloyi a titaniyamu. Makamaka mu mankhwala a mano, pafupifupi madontho onse a mano omwe ayesedwa amapangidwa ndi titaniyamu yoyera ya mafakitale ndi aloyi a Ti-6Al-4V, omwe ali ndi biocompatibility yabwino, katundu wamakina, komanso kukana dzimbiri. Kumbali ina, chifukwa chaubwino wocheperako komanso magwiridwe antchito abwino a titaniyamu ndi ma aloyi a titaniyamu, amagwiritsidwa ntchito kwambiri pazida zambiri zamasewera monga makalabu a gofu, mitu ya mpira, ma racket a tennis, ma racket a badminton, ndi zida za usodzi. Zopangidwa ndi iwo ndizopepuka, zili ndi chitsimikizo chaubwino, ndipo ndizodziwika kwambiri pakati pa anthu. Mwachitsanzo, SP-700 titanium alloy yatsopano yopangidwa ndi Japan Steel Pipe Company (N104) imagwiritsidwa ntchito ngati zinthu zapamwamba za Taylor brand 300 series golf heads, zomwe zikugulitsidwa kwambiri pamsika wa gofu wapadziko lonse lapansi. Kuyambira chakumapeto kwa zaka za m'ma 1900, ma aloyi a titaniyamu apanga pang'onopang'ono kukula kwa mafakitale ndikukula m'magawo monga petrochemical, aerospace, biomedical, makampani amagalimoto, masewera ndi zosangalatsa, kuyambira pakuwunika koyambirira mpaka kukwezedwa ndi chitukuko champhamvu.
