2022-08-15

1. intshayelelo

 Ukusukela ngeminyaka yee-1940s, itekhnoloji ye-vacuum brazing iye yaba yitekhnoloji ethembisayo ye-welding. I-Brazing yobhedu kunye neengxenye zensimbi ezingenasici zivele kuqala kwishishini le-elektroniki. Kamva, ngophuhliso olukhawulezayo lweshishini lokubhabha, ishishini lombane, ishishini lemoto, ishishini lejenereyitha yeoksijini kunye ne-rocket kunye netekhnoloji ye-missile, itekhnoloji ye-vacuum brazing nayo yaphuhliswa ngokufanelekileyo. Itekhnoloji ye-vacuum brazing isetyenziswa ngokubanzi ekwenzeni iipaneli zesangweji ye-honeycomb, iindibano zeenjini ze-jet kunye nezixhobo ezijulwayo ze-rocket, izihluzi zetsimbi, ii-waveguides kunye neeradiyetha ezahlukeneyo.

2. Yintoni i-vacuum brazing

I-vacuum brazing ibhekiselele kwindlela yenkqubo yokubrawuza ngokusebenzisa intsimbi yentsimbi yokugalela intsimbi ngaphandle kokuguquguquka kwindawo ephezulu yokufunxa.

Umgaqo wokusebenza:

Intsimbi yokuzalisa ibrazing igqunywe kumphezulu wamalungu ukuze ivacuum ibraze, emva koko ifakwe kwi-vacuum. ivacuum yokutshisa iziko. Inkqubo yokufunxa iqala ukusebenza kwaye umoya ukhutshwa ngaphandle. Xa idigri ye-vacuum ifikelela kwi-10-3Pa ye-vacuum state, ukufudumeza kuqala, kwaye ukufudumeza kufikelela kwi-10-3Pa. Kwiqondo lokushisa elifunwa yinkqubo, i-metal filler metal iqala ukunyibilika, kwaye i-liquid brazing filler metal imanzisa isiseko sesinyithi kwaye izalise isithuba phakathi kwe-drill bits phantsi kwesenzo se-capillary. Ngelo xesha, izinto ze-solder zisasazeka kwisiseko sesinyithi, kwaye isiseko sesinyithi sinyibilika kwi-solder yolwelo ukwenza i-joint brazing esemgangathweni.


3. Izinto eziluncedo zokuqhola ivacuum

  • Kwinkqubo ye-vacuum brazing, i-workpiece yokudibanisa iphantsi kweemeko ze-vacuum, kwaye akuyi kubakho i-oxidation, ukwanda kwekhabhoni, i-decarburization kunye nokuchithwa kokungcola. Ukucoceka komdibaniso odibeneyo kulungile kwaye amandla aphezulu.

  • Xa i-braking, ukushisa okutshisayo kuphantsi kunomgangatho wokunyibilika kwesiseko sesinyithi, esinempembelelo encinci kwizinto ezisisiseko, yonke inxalenye ifudumala ngokulinganayo, kwaye uxinzelelo lwe-thermal luncinci, kwaye i-deformation inokulawulwa ubuncinane, eyona nto ifaneleka ngokukodwa ukubethelwa kweemveliso ezichanekileyo.

  • Uxinzelelo oluphantsi (i-vacuum) ejikeleze isiseko sesinyithi kunye nentsimbi yokugubungela i-brazing inokuphelisa iigesi eziguquguqukayo kunye nokungcola okukhutshwe yintsimbi kwiqondo lokushisa lokutshisa, kwaye inokuphucula ukusebenza kwesiseko sesinyithi.

  • Indlela yoyilo lwemveliso iye yandiswa, kwaye iinxalenye brazable zivumelekile ukuba imijelo emxinwa, iitafile zenguqu encinane kakhulu, imingxuma ezingaboniyo, njl. Ngokukodwa ilungele iinxalenye ezinezikhongozeli ezivaliweyo kunye neemilo ezintsonkothileyo, kwaye ziyakwazi ukunyanyiswa kwiipasiti ezininzi. ngexesha. Inomsebenzi ophezulu wokubhobhoza kwaye ayifuni ukuqwalasela iingxaki zokubola, ukucocwa kunye nomonakalo obangelwa yi-flux, njl.

  • Inkqubo yokushisa ukushisa kwe-workpiece inokugqitywa ngexesha elifanayo ngexesha lokuqhaqha, iiparitha zenkqubo ye-welding efanelekileyo inokukhethwa, kwaye ukunyanyiswa kunokulungiswa njengenkqubo yokugqibela yokufumana i-brazed joint esebenza ngayo ihlangabezana neemfuno zoyilo.

  • Kukho iintlobo ezininzi zetsimbi ezinokubhobhoza, ngokukodwa ezifanelekileyo i-aluminium kunye ne-aluminium alloys, i-titanium kunye ne-titanium alloys, insimbi engenasici, i-alloys ephezulu yokushisa, njl.; kwakhona ilungele ukudibaniswa kwe-brazing ye-titanium, i-zirconium, i-niobium, i-molybdenum, i-tungsten kunye nezinye izinyithi ezifanayo okanye ezingafaniyo; Kwakhona kufanelekile kwizinto ezidibeneyo, i-ceramics, igraphite, iglasi, idayimane kunye nezinye izinto.

4.Esona sicelo siphambili setekhnoloji ye-vacuum brazing

  • Injini yomoya

I-vacuum brazing isetyenziswa ngokubanzi kwizakhiwo ze-honeycomb njengezinto zokutywinwa kweentlobo ezahlukeneyo zee-injini ze-aero. Inkqubo yokuqhafaza kwesakhiwo se-honeycomb kukulungiselela kwangaphambili i-brazing material in the honeycomb core, uze udibanise i-honeycomb kunye negobolondo, kwaye ekugqibeleni uthabathe indlela yokutshiza i-vacuum Ukukhangela, amandla okubambisana okudibeneyo malunga ne-50% yezinto ezisisiseko. I-stator blades edibeneyo ye-aero-injini ye-compressor nayo yenziwe yile ndlela yokuqhayisa. Iqulethwe ngamakhonkco angaphakathi nangaphandle kunye namacwecwe angaphezu kwe-10 adityaniswe nge-vacuum brazing. kuko konke.

Ukongeza, i-vacuum brazing ikwasetyenziswa ekwenzeni izikhokelo ze-turbine, i-vanes yesikhokelo, i-diffusers, iityhubhu zomlilo, izihluzi zeoyile kunye nezinye izinto kwii-injini ze-aero.
