Kuvimbika kweRotor Kana Iine Tembiricha Yakanyanya Uye Ichishanda Nguva Refu Zvinova Chinhu Chitsva Mukunyunguduka kweAluminium

Sezvo mitsetse yekugadzira aluminium yepasi rose ichiramba ichienda mberitembiricha yakakwira, kugadzirwa kwenguva refu, uye kudzimwa kwekugadzirisa kushoma, kuve nechokwadi chekuti marotor anobvisa gasi regirafiti anoramba akagadzikana uye akavimbika mumamiriro ezvinhu akaoma kwave chinhu chikuru chinonetsa zvirimwa zvinonyungudutsa aruminiyamu.

Munguva pfupi yapfuura, kambani inogadzira mainjiniya epamusoro uye inovhara jira muindasitiri yakatanga nzira yekusimbisa girafu inobvisa gasi yegirafu inoshanda mumamiriro ekupisa kwakanyanya uye kwenguva refu. Mhinduro iyi yakatoshandiswa mumafekitori akati wandei earuminiyamu uye iri kukwezva vanhu vakawanda.

1. Kupisa Kwakanyanya + Kutenderera Kurefu

Nekuvandudzwa kwezvigadzirwa zvealuminium alloy uye kuwedzera kwehuwandu hweotomatiki, nguva yekunyunguduka nekukanda mitsetse yakawanda yakawedzera zvakanyanya. Iye zvino zvakajairika kuti marotor anyudzwe mualuminium yakanyungudutswa pa700–750 °C kana kutopfuurakwenguva yakareba uchitenderera nguva dzose.

Mumamiriro ezvinhu aya, marotor e graphite akajairika anowanzoita zvinotevera:

• Kukurumidza kuoxidation yekupisa kwakanyanya, zvichikonzera kukurumidza kupwanyika uye kupwanyika kwenzvimbo;

• Kutsemuka kana kutotyoka nekuda kwekukanganiswa kwekupisa pamwe chete uye kushushikana kwemuchina;

• Kukweshana kwejira nekukweshana kunokonzerwa nekusawirirana kwekuwedzera kwekupisa pakati pejira negirafiti;

• Kudzikira kunoonekwa mukushanda kwekubvisa gasi nekufamba kwenguva, zvichikonzera zvikanganiso zvakawanda zvekuboorwa kwemhepo.

2.Kubva paZvinhu kusvika pakuputira

Kune mamiriro ekushanda anodziya zvakanyanya uye kwenguva refu, mhinduro itsva ndeyekwetekungo "wedzera chifukidziro" pamarotor aripo. Pane kudaro, inogadzirisa sisitimu yese - kubva pakusarudza substrate yegraphite uye chimiro cherotor kusvika kusystem yecoating uye kudzora maitiro:

• Sarudzo yakanatswa ye graphite substrate
  Nekudzora huwandu hwegraphite, chimiro chepore, uye hunhu hweanisotropic, mhinduro inoderedza huwandu hwemukati mekushushikana uye nzira dzeoxidation, zvichiisa hwaro hwakasimba hwekushanda kwenguva refu pakupisa kwakanyanya.

• Chimiro cheRotor chakagadzirirwa kuvimbika
  Impeller, nzira dzekuyerera kwemvura, uye zvikamu zvekuchinja zvinogadziriswa nenzira yekuvaka kuti zvibvise makona akapinza uye zvikamu zvisina kusimba munzvimbo dzine kushushikana kwakanyanya, zvichivandudza kuramba kupisa.

• Mapfekero ekupisa kwakanyanya ane pfungwa "dzinoenderana"
  Masisitimu ekuputira akagadzirwa necomposite ane macoefficients ekuwedzera kwekupisa ari pedyo negraphite anoshandiswa. Izvi hazvingopi chete oxidation yakanaka uye kuramba ngura, asiwo zvinoderedza kutsemuka nekubviswa kweganda kunokonzerwa nekusawirirana kwekupisa.

• Kudzora maitiro kwakatarisana ne "matete uye akafanana" zvidimbu
  Kuburikidza nekurapa kwekutanga kwematanho akawanda uye maitiro ekudzora machira, mushonga unovandudza kuwanda kwemavara uye kunamira, zvichidzivirira kuratidzwa kwekutanga kwegirafiti pasi pekutenderera kwenguva refu uye kukanganiswa.

3. Mhedzisiro yeMunda

Mumiti yekunyungudutsa aruminiyamu yakashandisa itsvamarotor ekubvisa gasi regirafiti, mhedzisiro pasi pemamiriro ezvinhu akafanana ekuita zvinosanganisira:

• Nguva yebasa yakawedzerwa zvakanyanya pa rotor imwe neimwe, nekutsiviwa kwe rotor kushoma;

• Kushanda kwakasimba kwekubvisa gasi, nekusapinda kwemvura uye zvichemo zvekubatanidzwa mumakwikwi marefu ekukanda;

• Kuderedzwa kwenguva yekushanda kwekugadzirisa, zvichikonzera nguva yakawanda yekushanda kwemutsetse uye kubereka;

• Kuderera kukuru kwezviitiko zvinongoerekana zvaitika zvinokonzerwa nekutyoka kwerotor kana kucheka kwecoating.

Zvinotarisirwa kuti chero ani zvake anogona kutanga agadzirisa matambudziko ekuvimbika kwemarotor ekubvisa gasi egraphite pasi pekushanda kwenguva refu uye kwenguva refu achawana mukana wekutanga muchikamu chinotevera chekuvandudza maitiro ekunyungudutsa aruminiyamu. Panyaya yekuti "kubata nemaitiro akaomarara," kuiswa kwehunyanzvi uye zvigadzirwa kwave nzvimbo itsva yekurwa uko indasitiri yearuminiyamu nevatengesi verotor vari kuwedzera kushanda kwavo.
