Zofunikira zachitukuko cha zingalowe m’mlengalenga ng’anjo

Pachitukuko chaukadaulo wocheperako wopanda oxidizing, kupangidwa kwa ng’anjo ya vacuum atmosphere ndikofulumira. Pazigawo zing’onozing’ono zamakono komanso kupanga misa, makamaka kuzimitsa kowala, kuzimitsa, kuzimitsa moto, kuzimitsa mpweya wa carbonitriding, ndi mpweya wa nitrocarburizing wa chitsulo cha kaboni ndi mbali zonse zazitsulo za aloyi zimatengera kugwiritsa ntchito njira zowongolera. Choncho, mpweya ng’anjo kutentha kutentha akadali chigawo chachikulu cha zipangizo zamakono kutentha mankhwala.

Gwero la gasi la mlengalenga wokonzekera. Pokhala odziwa bwino komanso kulimbikitsa chilengedwe chokhazikika, dziko lathu lafika patali kwambiri kuthetsa vuto la mlengalenga. The oyambirira endothermic mpweya jenereta makamaka liquefied mpweya, ndiye propane kapena butane ndi apamwamba chiyero. M’zaka zaposachedwa, zatsimikiziridwa kuti chuma chochuluka cha gasi cha dziko langa chapanga mikhalidwe yabwino yokonzekera ma endothermic atmospheres ndi methane. Kugwiritsiridwa ntchito kwa chikhalidwe cha mbadwo wachindunji popanda ng’anjo yaiwisi ndi njira yomwe singanyalanyazidwe.

Zida zotenthetsera ng’anjo ya vacuum atmosphere. Ng’anjo yosindikizidwa yamitundu yambiri komanso mizere yopangira ng’anjo yamitundu yambiri imakhala ndi zodziwikiratu, kusinthasintha kwakukulu kopanga komanso kugwiritsa ntchito mwamphamvu, kotero amagwiritsidwa ntchito kwambiri.

Kusokoneza pang’ono kwa workpiece ndi mwayi wofunikira kwambiri wa ng’anjo ya vacuum atmosphere. Malingana ndi zochitika zapakhomo ndi zakunja, kupotoza kwa ng’anjo ya mumlengalenga ndi gawo limodzi mwa magawo atatu a kutentha ndi kuzimitsa mchere. Ndikofunikira kwambiri kuphunzira njira zowotchera vacuum zazinthu zosiyanasiyana ndi magawo omwe ali ndi zovuta zosiyanasiyana komanso malamulo opotoka pansi pazikhalidwe zosiyanasiyana zoziziritsa, ndikufanizira ndi kompyuta, yomwe ili yofunika kwambiri pakukweza ukadaulo wa ng’anjo ya vacuum atmosphere. . Kufanana kwa mpweya wotuluka panthawi ya kutentha kwa vacuum, kuthamanga kwabwino kapena kuthamanga kwa mpweya wozimitsa kumakhala ndi chikoka chachikulu pa kuzimitsa ndi kubalalitsidwa kwabwino kwa zigawo. Kugwiritsa ntchito njira zofananira zamakompyuta pophunzira malamulo oyendetsa mpweya mu ng’anjo ndikofunikira kwambiri pakuwongolera kusintha kwa ng’anjo. Vacuum carburizing ndi njira yotheka yopezera kutentha kwambiri kwa carburizing.

Komabe, kutentha kwa nthawi yayitali pa kutentha kwakukulu kumapangitsa kukula kwambewu ya austenite yazitsulo zambiri kukula kwambiri. Kwa carburization yachitsulo yotentha kwambiri, chikoka cha kutenthedwa ndi kuzimitsa zinthu zakuthupi ndi zogwirira ntchito zidzaphunziridwa, ndipo kukhathamiritsa kwa kulowetsedwa kwa vacuum kudzaphunziridwa. Mpweya, kuzizira, kutentha ndi kuzimitsa ndi zipangizo ndizofunikira. M’zaka zaposachedwa, pakhala kafukufuku wapadziko lonse lapansi ndi chitukuko cha ng’anjo zamtundu woyaka moto pogwiritsa ntchito mafuta a gasi. Ndikovuta kwambiri kugwiritsa ntchito mafuta a gasi kutenthetsa mu ng’anjo ya vacuum atmosphere. Ngakhale pali mawu oti kupulumutsa mphamvu, sikuti ndi njira yofunikira yachitukuko.
