Mafuta ekuvhara-mavharuvhu akakosha zvikamu mukati mehurongwa sezvo achimiririra chinhu chakanaka chekuchengetedza mudziyo. Basa guru rinoitwa nemudziyo uyu nderekudzivisa uye kuvhara mafuta asati asvika pamoto, nokudaro kudzivisa kupisa kwekushisa kwedunhu kupinda muhurongwa kubva pakusvikwa. Izvi zvinomiririra nzira yekudzivisa kukanganisa kuhurongwa pachahwo asiwo kune vanhu vari pedyo nayo.

Ivhavha yekuvhara mafuta inoshanda sei?

Pane zvikamu zviviri zvakakosha zvevhavha:
- Muviri wevhavha: mukati umo mafuta, mvura kana gasi, inopfuura;
-Chishandiso chekudzora: chakashongedzerwa nechinhu chinonzwisa tsitsi.
Ivhavha yevhavha yakabatanidzwa kune chigadziro chekutonga uye inokonzera kuvhara kwevhavha kana zvichidiwa. Kana zvinhu zvose zvichishanda nemazvo, tsvimbo yekuvhara inozorora papiston uye inova nechokwadi chekupfuura kwemafuta. Zvisinei, kana kukanganisa kana kukanganisa kukaitika, piston inofamba uye inokonzera kuvhara nekudzikisa tsvimbo yekuvhara. Ndedzipi nyaya idzi?
- Kuwedzera kwekuwedzera kwemvura: piston inofamba kuruboshwe uye inoita kuti tsvimbo iburuke, ichivhara nzira yemafuta;
- Kuputsika kwecapillary: piston inofamba ichienda kurudyi uye inokonzera, zvakare, kuburuka kwetsvimbo nekuvhara kwechikamu.
Kamwe vharafu ichivhara, zvinokwanisika kudzokera kukushanda chete kuburikidza nebhuku rekugadzirisa rinogona kuitika chete kana mvura ine tembiricha iri pasi pe87 ° C uye capillary haina kuputsika kana kukuvara.
