Kuyeza Ubwino Wamkati

Kuonetsetsa kuti mkati mwa ma castings, njira zingapo zimagwiritsidwa ntchito kuti zizindikire zolakwika zapansi panthaka zomwe sizikuwoneka ndi maso. Njirazi zikuphatikizapo:

Zithunzi za X-ray:Njirayi imagwiritsa ntchito ma X-ray kuti apange zithunzi zamkati mwazojambulazo. Ndiwothandiza kwambiri pozindikira ming'alu yamkati, porosity, ndi inclusions.

Mayeso a Ultrasonic (UT):Mafunde akupanga amafalitsidwa kudzera mukuponya, ndipo zowunikira zimawunikidwa kuti zizindikire discontinuities mkati kapena zolakwika.

Kusanthula kwa Computed Tomography (CT).: Mawonekedwe apamwamba kwambiri a X-ray radiography yomwe imapereka chithunzi cha 3D cha kuponyera, kulola kusanthula mwatsatanetsatane zamkati.

Njira zowunikira bwino zandalama castingszambiri zikuphatikizapo: Dimensional Inspection,X-ray ndi CT scanning.

 

Kuyesa Kopanda Kuwononga (NDT)

Njira zoyesera zosawononga ndizofunikira pakuwunika mtundu wa castings popanda kuwononga ziwalozo. Njira zodziwika bwino za NDT ndi izi:

Kuyeza kwa Magnetic Particle (MPT): Njira imeneyi kumafuna magnetizing ndi kuponyera ndi ntchito ansomba particles pamwamba. Zowonongeka zilizonse zapamtunda kapena pafupi ndi pamwamba zipangitsa kuti tinthu tiwunjikane, ndikupangitsa kuti ziwonekere pansi pa kuwala kwa ultraviolet.

Kuyeza kwa Dye Penetrant (DPT): Utoto wamadzimadzi umagwiritsidwa ntchito pamwamba pa kuponyera. Pambuyo pa nthawi yokhazikika, utoto wowonjezera umachotsedwa, ndipo wogwiritsa ntchito amayikidwa. Chilema chilichonse chimapangitsa kuti utotowo utuluke, kuwulula zolakwika zake.

Eddy Current Testing (ECT): Njirayi imagwiritsa ntchito ma elekitiromagineti induction kuti izindikire zolakwika zapamtunda ndi pafupi ndi pamwamba pa zinthu zoyendetsa.

 

Mapulogalamu ndi Njira Zoyendera Zofananira

Mitundu yosiyanasiyana ya ma castings imafunikira njira zowunikira zenizeni potengera momwe amagwiritsidwira ntchito komanso katundu wawo. Nazi zitsanzo zingapo:

Zida Zagalimoto: Zigawo zofunika kwambiri monga midadada ya injini, mitu ya silinda, ndi zida zoyimitsidwa nthawi zambiri zimawunikiridwa pogwiritsa ntchito X-ray radiography ndi kuyesa kwa ultrasonic kuti zitsimikizire kuti zimatha kupirira kupsinjika kwa ntchito.

Zida Zamlengalenga: Chifukwa cha zofunikira zachitetezo chokhazikika, zowulutsa zakuthambo zimawunikiridwa mozama pogwiritsa ntchito CT scanning ndi kuyezetsa akupanga kuti zitsimikizire kukhulupirika komanso kudalirika.
