Cold Anapanga Welded Kapangidwe ka Moto Chitoliro Line

Kapangidwe Kozizira Kopangidwa ndi Chitoliro cha Moto Chithunzi Chowonetsedwa

Kufotokozera Kwachidule:

Mapaipi olumikizidwa ndi msoko wozungulira amagwira ntchito yofunika kwambiri m'mafakitale osiyanasiyana, makamaka m'mapangidwe opangidwa ndi msoko wozizira komanso m'mizere ya mapaipi amoto. Mapaipi awa amapangidwa mwa kupindika zitsulo mosalekeza kukhala mawonekedwe ozungulira kenako n'kulumikiza mizere yozungulira kuti apange mapaipi ataliatali opitilira. Amagwiritsidwa ntchito kwambiri ponyamula zakumwa, mpweya ndi zinthu zolimba, komanso m'mafakitale ndi mafakitale.

Mapaipi awa nthawi zambiri amapangidwa ndi chitsulo chapamwamba kwambiri ndipo amatha kupirira katundu wolemera, zomwe zimapangitsa kuti akhale abwino kwambiri pa milatho, nyumba ndi mapulojekiti ena a zomangamanga.

a. Njira yochotsera poizoni m'thupi imatchulidwa motere:
FF: Chitsulo chophwanyika bwino chokhala ndi zinthu zomangira nayitrogeni mu kuchuluka kokwanira kumangirira nayitrogeni yomwe ilipo (monga osachepera 0,020% ya Al yonse kapena 0,015% ya Al yosungunuka).
b. Mtengo wapamwamba kwambiri wa nayitrogeni sugwira ntchito ngati mankhwala akuwonetsa kuchuluka kwa Al komwe kuli 0,020% ndi chiŵerengero chochepa cha Al/N cha 2:1, kapena ngati pali zinthu zina zokwanira zomangira N. Zinthu zomangira N ziyenera kulembedwa mu Chikalata Chowunikira.

Komanso, chitetezo cha motomapaipi, kugwiritsa ntchito mapaipi olumikizidwa ndi msoko wozungulira ndikofunikira kwambiri kuti dongosololi likhale lotetezeka komanso lodalirika. Mapaipi awa adapangidwa mwapadera kuti athe kupirira kutentha kwambiri ndi kupsinjika ndipo ndi oyenera kugwiritsidwa ntchito m'makina oteteza moto. Kapangidwe ka chitoliro cholumikizidwa ndi msoko wozungulira kamaonetsetsa kuti sichikutuluka madzi ndipo chimasunga kapangidwe kake ngakhale pakakhala zovuta kwambiri, zomwe zimapangitsa kuti chikhale gawo lofunikira la makina oteteza moto ndi makina oletsa moto.

Chimodzi mwa zabwino zazikulu zachitoliro chozungulira cholumikizidwandi kusinthasintha kwake komanso kusinthasintha kwake kuti zigwirizane ndi ntchito zosiyanasiyana. Mapaipi awa amatha kupangidwa m'makulidwe osiyanasiyana kuti akwaniritse zofunikira za polojekiti. Kuphatikiza apo, amatha kuphimbidwa ndi zinthu zoteteza kuti awonjezere kukana dzimbiri ndikuwonjezera nthawi yawo yogwirira ntchito, zomwe zimapangitsa kuti akhale oyenera kugwiritsidwa ntchito m'malo ndi mikhalidwe yosiyanasiyana.

Mapaipi olumikizidwa ndi msoko wozungulira ali ndi ubwino womveka bwino pankhani yokhazikitsa ndi kukonza. Ndi opepuka komanso osinthasintha, zomwe zimapangitsa kuti zikhale zosavuta kunyamula ndi kusamalira, zomwe zimachepetsa nthawi yoyika ndi ndalama zogwirira ntchito. Kuphatikiza apo, kutalika kwake kwakutali komanso kosalekeza kumachepetsa kufunikira kwa maulumikizidwe ena, kuchepetsa chiopsezo cha kutuluka kwa madzi ndikuwonetsetsa kuti mapaipi azikhala ogwira ntchito bwino komanso odalirika.

Pomaliza, chitoliro cholumikizidwa ndi msoko wozungulira ndi gawo lofunikira m'mafakitale osiyanasiyana, makamaka m'nyumba zolumikizidwa zozizira komansochingwe cha chitoliro cha motontchito zake. Kapangidwe kake kolimba, magwiridwe antchito apamwamba komanso kusinthasintha kumapangitsa kuti ikhale chisankho choyamba kwa mainjiniya, makontrakitala ndi oyang'anira mapulojekiti. Kaya kumanga nyumba zolimba kapena kupanga njira zodzitetezera ku moto zotetezeka komanso zodalirika, mapaipi olumikizidwa ndi msoko wozungulira ndi yankho lofunikira kwambiri pazosowa za zomangamanga zamakono ndi mafakitale.
