1. Kusintha kwa boiler. Posankha chowotchera, "chiwopsezo" chiyenera kuganiziridwa bwino. "Impact load" imatanthawuza zida zomwe zimagwiritsa ntchito nthunzi kwakanthawi kochepa, monga zida zochapira madzi. 60% ya kumwa kwa nthunzi ya zida zochapira madzi amadyedwa mkati mwa mphindi zisanu. Ngati chowotcheracho chasankhidwa chaching'ono kwambiri, malo otulutsa mpweya m'bowolo ndi osakwanira, ndipo madzi ambiri amatulutsidwa panthawi ya nthunzi. Kugwiritsa ntchito kutentha kumachepetsedwa kwambiri. Pa nthawi yomweyi, potsuka makina otsuka, kuchuluka kwa mankhwala opangira mankhwala kumatsimikiziridwa pansi pa madzi ena. Ngati chinyezi cha nthunzi chikukwera kwambiri, kupatuka kwa madzi a makina ochapira kudzakhala kwakukulu kwambiri panthawi yotentha, zomwe zimakhudza ubwino wa nsalu. Kuchapa zotsatira.
2. Kukonzekera kwa chowumitsa kumafunika kukwaniritsa zofunikira za makina ochapira osiyanasiyana posankha. Nthawi zambiri, mphamvu ya chowumitsira iyenera kukhala yokwera kwambiri kuposa ya makina ochapira, ndipo kuchuluka kwa chowumitsira kumafunika kukhala mulingo umodzi wapamwamba kuposa wa makina ochapira. Chiŵerengero cha voliyumu chikuwonjezeka ndi 20% -30% kutengera mulingo wadziko lonse kuti ziwongolere bwino zowumitsa. Chowumiracho chikaumitsa zovala, mpweya ndi umene umachotsa chinyezi. Malinga ndi mulingo wapano wa dziko, kuchuluka kwa zowumitsa ndi 1:20. Kumayambiriro kwa kuyanika, chiŵerengero ichi ndi chokwanira, koma nsaluyo ikauma mpaka pamlingo wina, imakhala yotayirira. Pambuyo pake, kuchuluka kwa bafuta mu thanki yamkati kumakhala kokulirapo, komwe kudzakhudza kulumikizana pakati pa mpweya ndi nsalu, potero kukulitsa nthawi yosungira kutentha kwa bafuta.
3. Mukayika payipi ya nthunzi ya chidacho, ndi bwino kuti muyike payipi ya nthunzi. Chitoliro chachikulu chiyenera kukhala chitoliro chokhala ndi mphamvu yofananira mofanana ndi momwe kungathekere. Gulu la valve kuchepetsa kuthamanga liyenera kuikidwa pambali pa katunduyo. Kuyika kwa mapaipi a zida kumakhudzanso kugwiritsa ntchito mphamvu. Pansi pa kuthamanga kwa 10Kg, chitoliro cha nthunzi chimakhala ndi 50 mm, koma pamwamba pa chitoliro ndi 30% yaing'ono. Pansi pazikhalidwe zomwezo zotchinjiriza, nthunzi yomwe imadyedwa ndi mapaipi awiri omwe ali pamwambapa pa mita 100 pa ola ndi pafupifupi 7Kg yocheperako kuposa yomaliza. Choncho, ngati n'kotheka, tikulimbikitsidwa kuti muyike payipi ya nthunzi ndikugwiritsa ntchito chowotchera ndi mphamvu yofanana yomwe mungathe pa chitoliro chachikulu. Kwa mapaipi, gulu la valve kuchepetsa kuthamanga liyenera kuikidwa pambali pa katunduyo.
