Heat nemishonga simbi turboproizvodstve. Unhu Main mashoko

Heat nemishonga steels uye alloys sezvo rinokosha mhando zvokuvakisa akatanga kushandiswa zvikuru kwazvo maererano kukura turbine kuvakwa indasitiri. Turbine ive simba rine kana transducer kushandiswa chafariz simba zvokushandisa, ndege uye chikepe injini. Tichishandisa yapfuura kwave kune kuwedzera kwezviito gasi turbine magadzirirwo pasi tikaisa wemari (marori, locomotives).

Kuwedzera gasi Inlet tembiricha ipfupi chaizvo mafuta kudyiwa chete chikwata simba. Panyaya iyi, ari kumbonyanya pfupi pakanga kupisa nemishonga simbi. Nhasi zvinhu izvi vari turbine mazano vari kusvika 50% of zvachose uremu.

Heat kuramba simbi ndiyo zvinhu basa kwete chete panguva yakakwirira tembiricha. Hazvina kushanda mu mamiriro slozhnonapryazhennogo hurumende kwenguva akafanorongerwa nguva kumwedzi. The chikuru tsika anosarudza chokupika vakati zvinhu zvakakwirira-tembiricha simba.

Under uhwu asinganzwisisi zvinokonzera inoenda kukuparadzwa munhu akapiwa deformation mupfungwa iyo inokwanisa kutsigira simbi zvinhu neimwe akaitwa panguva imwe tembiricha wakapiwa kwenguva chaiyo nguva. Apo waiti nguva uye voltage, asi maitiro rinonzi tensile simba (refu). Kana zvikaonekwa deformation, nguva uye kunetseka, unhu inonzi simba zvinokambaira.

Heat nemishonga steels vane, kunze simba, ductility, izvo zvinofanira kuchengetedzwa kusvikira pakuguma kushanda. In mashoko plasticity Matura zvinofungidzirwa rakavimbika simbi rishande.

The chinokosha chakanangana mashoko acho notch wanda. Unhu uhwu akatsunga muchimiro ukama paakapera nguva kusvikira kukundikana kumeso uye notched specimens akaedzwa nenguva tembiricha kunetseka. Heat nemishonga steels vaiona hanya notch ari reshiyo akaenzana kana kupfuura kubatana.

Nokuti kuti kuwedzera kusvika uchishandisa tembiricha kunoitika pamusoro nguva, apo oparesheni anoenderana pakutanga, kazhinji chinhu tembiricha ambient, chikuru pfungwa rwakabhadharwa kuna zvinokosheswa elasticity uye simba. Zvakakosha kuti tsika dzinoitwa mashoko ari mumba tembiricha akanga akakwirira zvakakwana.

Nokuti kuti kupisa nemishonga steels slozhnonapryazhennogo wakashanda pasi mamiriro iyo kunoratidzwa chenguva nokuchinja chiratidzo uye kukosha kwakaita mutoro, pasina kukosha uye yakakwirira kuneta nemishonga.

Nhasi kushandiswa chakaoma michina negadziriso pakusikwa zvivako necessitates vane simbi zvinhu kuva mukuru rwokugadzira maitiro. Saka, muna zvaAtemisi mashizha ari gasi turbine injini inoshandiswa nokuchengetedza, zvakarurama nokuchengetedza, makorari, zvokuimba kubudiswa nzira uye vakaipedza nyaya pematanda, zvakarurama Kudzingwa, pakuonekwa. Kugadzirwa combustion makamuri nokupisa nemishonga simbi machira kunoitwa pachishandiswa chitsidzo, kuchitonhora aindiumba, gwapa nomoto uye dzimwe ruzivo. Rakajairika unyanzvi vari Welding electrode kukweshera diffusion chokuedza, brazing zvigadzirwa. manipulations zvose izvi zvinoda hwaivapo zvechadenga zvinhu zvaishandiswa.

Superalloys uye simbi nomuzvarirwo vanokwanisa kuramba yakawedzera simba zviratidzo kuti vashandi uye kuti ribude tembiricha. Izviwo, zvinoisa chaiyo mucherechedzo pamusoro simbi redistribution yose michina inoshandiswa, pamwe deformation pamusoro vara uye asati yokupedzisira chose kushandiswa, zvigadzirwa kune inodiwa pamusoro kumeso uye mukakumbira miganhu.
