Ndodo ya ku Poland

Kufotokozera Kwachidule:

Ndodo ya ku Poland ndi mtundu wa ndodo yapadera yolumikizirana ndi ndodo yolumikizirana ndi beam hanger. Ili pamwamba pa ndodo yolumikizirana, iyenera kukhala ndi mphamvu zambiri, kotero ndi mainchesi akulu komanso chitsulo chapamwamba kuposa ndodo yolumikizirana, ndipo pamwamba pake ndi posalala kwambiri.

1. Ndodo ya ku Poland ndi mtundu wa ndodo yapadera yolumikizirana ndi ndodo yolumikizirana ndi cholumikizira cha beam. Ili pamwamba pa ndodo yolumikizirana, iyenera kukhala ndi mphamvu zambiri, kotero ndi mainchesi akulu komanso chitsulo chapamwamba kuposa ndodo yolumikizirana, ndipo pamwamba pake ndi posalala kwambiri.

2. Ntchito yaikulu:

Kuphatikiza ndi kulongedza komwe kumayikidwa mu bokosi lolongedza kuti kutseke mutu wa chitsime ndikuletsa mafuta, gasi, madzi kutuluka.

Cholumikizira chapakati pakati pa ndodo yonyowa ndi chopachikira mutu cha nyulu

Kuyesa chithunzi chosonyeza kumaliza.

Malizitsani ntchito zosiyanasiyana zoyendetsera chitsime, monga kupopera pampu, kukonza bwino momwe pampu imagwirira ntchito.

Dziwani: Ngati mphamvu yocheperako ya zokolola singathe kuyezedwa, iyenera kuganiziridwa kuti yakonzedwa kukhala chitsanzo chokhazikika ndikuyika extensometer kuti muyese.
A Kawirikawiri imapangidwa ndi chitsulo cha kaboni chapamwamba kwambiri, chomwe chimatha kufikira mphamvu zamakina za tebulo. Chitsulo cha molybdenum (koma osati cha mtundu uwu wa chitsulo) chimagwiritsidwa ntchito nthawi zambiri, ndipo chithandizo chogwira mtima cha kutentha chingapangitse kuti tebulo ili likhale ndi mphamvu zamagetsi.
