Njerwa zomangiraNdi zinthu zapadera zopinga, zomwe zimagwiritsidwa ntchito makamaka pokonza ndikuthandizira khoma lamkati la uvuni kuti zitsimikizire kukhazikika ndi kulimba kwa uvuni pansi pa kutentha kwambiri komanso malo ogwirira ntchito ovuta. Njerwa zomangira zimamangiriridwa ku khoma lamkati la uvuni ndi zomangira zapadera, zomwe zimatha kupirira kutentha kwambiri, kukanda kwa mpweya ndi kuwonongeka kwa zinthu, motero zimakulitsa nthawi yogwira ntchito ya uvuni ndikusunga kukhazikika kwa malo ogwirira ntchito a uvuni.
Zipangizo ndi mawonekedwe
Njerwa zomangira nthawi zambiri zimapangidwa ndi zinthu zopangira zosalimba monga aluminiyamu yambiri, magnesium, silicon kapena chromium, zomwe zimakhala ndi kukhazikika bwino komanso kukana dzimbiri kutentha kwambiri. Mawonekedwe ndi kukula kwake zimasinthidwa malinga ndi kapangidwe kake ndi zofunikira pa ntchito ya uvuni. Mawonekedwe wamba amaphatikizapo mawonekedwe amakona anayi, ozungulira ndi apadera.
Munda wofunsira
1. Makampani opanga zinthu zotayidwa: amagwiritsidwa ntchito popanga zinthu zotayidwa zotentha kwambiri monga zinthu zotayidwa, chitsulo chosapanga dzimbiri, zinthu zotayidwa zochokera ku nickel ndi zinthu zotayidwa za titaniyamu.
2. Makampani opanga zitsulo: amagwiritsidwa ntchito popangira ndi kukonza zida zotentha kwambiri monga makina opangira zinthu zopitilira muyeso, ng'anjo zopangira zitsulo, zosinthira, ng'anjo zotentha, ng'anjo zophulika ndi maiwe oyeretsera.
3. Makampani opanga simenti: amagwiritsidwa ntchito pokonza ndi kulimbitsa zida monga ma uvuni ozungulira, zoziziritsira, zotenthetsera zinthu zakale, ndi zina zotero.
4. Makampani opanga mafuta: amagwiritsidwa ntchito pokonza ndi kulimbikitsa zinthu monga mapaipi ndi matanki osungiramo zinthu m'mafakitale oyeretsera.
5. Makampani opanga magetsi: amagwiritsidwa ntchito pokonza ndi kulimbitsa zida monga ma boiler m'mafakitale amagetsi, uvuni ndi michira ya malo opangira magetsi otenthetsera omwe amayaka ndi malasha komanso omwe amayaka ndi gasi.
Makhalidwe a kapangidwe kake
Njerwa za nangula nthawi zambiri zimakhala ndi malekezero opachikika ndi matupi a nangula, ndipo zimakhala ndi kapangidwe ka mzati. Pamwamba pa thupi la nangula pali mipata ndi nthiti zomwe zimagawidwa nthawi ndi nthawi. Nthiti zimagwira ntchito yolimbitsa ndi kukoka, kukonza mphamvu yokoka ndi kusinthasintha komanso kupewa kusweka. Kuphatikiza apo, njerwa za nangula zimakhalanso ndi mawonekedwe a kuchuluka kwa voliyumu, mphamvu yokakamiza kwambiri, kukana kwamphamvu kwa spalling, kukhazikika bwino kwa kutentha komanso kukana kwamphamvu kwa kugunda.
