Pofuna kukwaniritsa miyezo yolimbana ndi kuphulika, mpandawo uyenera kuthana ndi kuphulika kulikonse komwe kumachitika mkati mwake ndikuletsa ziphuphu zomwe zimatsekedwa kuti zisatenthe nthunzi, mpweya, fumbi kapena ulusi mumlengalenga. Chifukwa chake, chitetezo cha kuphulika sikutanthauza kuti chitha kupirira kuphulika kwakunja zikafika pamakola amagetsi. Uku ndiye kuthekera kwa chassis kuteteza zipsera zamkati kapena zophulika kuti zisapangitse kuphulika kwakukulu.

Kutentha kwapamwamba kapena ziwalo zilizonse zamagetsi zomwe zitha kupezeka mumlengalenga wowopsa ziyenera kuyesedwa kuti zisapitirire 80% ya kutentha kwamphamvu kwa gasi kapena nthunzi m'dera lomwe zida zake zikuyenera kukhala ntchito.

Zida zophulika

Tanthauzo: Zipangizo zamagetsi zomwe sizimayatsa mpweya wophulika mozungulira momwe ziriri.

Kugawidwa m'magulu atatu:

Kalasi Woyamba: zida zamagetsi zapansi panthaka mumigodi yamakala;

Kalasi Yachiwiri: Zipangizo zina zonse zamagetsi zamagesi ophulika kupatula migodi yamalasha ndi migodi yapansi panthaka.

Kalasi Yachitatu: Zipangizo zamagetsi zomwe zimagwiritsidwa ntchito m'malo ophulika kupatula migodi yamalasha
