Chifukwa chiyani kapu ya thermos yomwe ndidagula imapanga phokoso lachilendo mkati ikagwiritsidwa ntchito kwakanthawi?

Chifukwa chiyani pali phokoso lachilendo mkati mwa kapu ya thermos? Kodi phokoso losazolowereka lingathe kuthetsedwa? Kodi kapu yamadzi yaphokoso imakhudza kagwiritsidwe ntchito kake?

Ndisanayankhe mafunso omwe ali pamwambawa, ndikufuna kuuza aliyense momwe kapu ya thermos imapangidwira. Inde, popeza pali njira zambiri zopangira makapu amadzi osapanga dzimbiri, sitidzafotokoza kuyambira pachiyambi. Tidzayang'ana kwambiri njira zopangira zokhudzana ndi phokoso lachilendo.

Pamene matupi amkati ndi akunja a kapu yamadzi osapanga dzimbiri amalumikizidwa palimodzi, koma pansi pa chikhocho sichinatenthedwe, kukonzanso kwapadera kumafunika pansi pa kapu. Kukonzekera kwapadera kumeneku ndikuwotcherera gitala kumbali ya pansi pa kapu moyang'anizana ndi mkati mwa kapu yamadzi. Kenaka pansi pa chikhocho amawotchedwa ku thupi la chikho chamadzi chimodzi ndi chimodzi mwadongosolo. Nthawi zambiri pansi pa chitsulo chosapanga dzimbiri thermos chikho wapangidwa 2 kapena 3 mbali.

Padzakhala bowo lotsekera pansi pa kapu yowotchera chotengera. Makapu onse amadzi asanatulutsidwe, mikanda yagalasi iyenera kuyikidwa padzenje. Mukalowa mu ng'anjo yowonongeka, ng'anjo ya vacuum idzagwira ntchito mosalekeza pa kutentha kwa 600 ° C kwa maola 4. Chifukwa kutentha kwakukulu kumapangitsa kuti mpweya pakati pa makoma awiri a masangweji ukule ndikufinyidwa kuchokera ku sangweji pakati pa makoma awiriwo, nthawi yomweyo, mikanda yagalasi yomwe imayikidwa m'mabowo a vacuum pambuyo pa kutentha kwa nthawi yayitali idzakhala. kutenthedwa ndi kusungunuka kuti atseke mabowo otsekera. Komabe, mpweya pakati pa makoma sudzatulutsidwa kwathunthu chifukwa cha kutentha kwakukulu, ndipo mpweya wotsalawo udzakongoletsedwa ndi getter yomwe yayikidwa mkati mwa kapu, motero kumapangitsa kuti pakhale mpweya wokwanira pakati pa makoma a khoma. chikho cha madzi.

Kodi nchifukwa ninji anthu ena amamva phokoso losazolowereka mkati akaligwiritsa ntchito kwa kanthaŵi?

Izi zimachitika chifukwa cha kumveka kwachilendo komwe kumabwera chifukwa cha getter yomwe ili pansi pa kapu ikugwa. The getter ali ndi mawonekedwe achitsulo. Pambuyo pa kugwa, kugwedeza kapu yamadzi kumapanga phokoso pamene ikuwombana ndi khoma la chikho.

Ponena za chifukwa chomwe getter imagwera, tidzagawana nanu mwatsatanetsatane m'nkhani yotsatira.
