Nkhani - Ubwino wa machubu opangidwa ndi zipsepse

Kusamutsa kutentha kuchokera kumadzi otentha kupita kumadzi ozizira kudzera pa khoma la chubu ndichifukwa chake ambiri aife timagwiritsira ntchito machubu opangidwa ndi zipsepse.Koma mungafunse, ubwino waukulu wogwiritsa ntchito chubu chopangidwa ndi zipsepse ndi chiyani?Bwanji osangogwiritsa ntchito chubu chokhazikika kuti musamutsire?Chabwino mungathe koma mlingo udzakhala wochepa kwambiri.

Posagwiritsa ntchito chubu chopangidwa ndi zipsepse, malo akunja sakhala okulirapo kuposa amkati.Chifukwa chake, madzimadzi omwe ali ndi gawo lotsika kwambiri lotengera kutentha amawonetsa kuchuluka kwa kutentha.Pamene kutentha kutengerapo koyefishienti wa madzimadzi mkati chubu ndi kangapo lalikulu kuposa madzimadzi kunja chubu lonse kutentha kutengerapo mlingo akhoza kwambiri bwino powonjezera kunja kudera la chubu.

Machubu omalizidwa amawonjezeka kunja kwa dera.Pokhala ndi chubu chokhala ndi zipsepse m'malo mwake, kumawonjezera kuchuluka kwa kutentha.Izi zimachepetsa kuchuluka kwa machubu ofunikira pakugwiritsa ntchito komwe kumachepetsanso kukula kwa zida zonse ndipo m'kupita kwanthawi kungachepetse mtengo wantchitoyo.Nthawi zambiri, chubu chimodzi chopangidwa ndi zipsepse chimalowetsa machubu asanu ndi limodzi kapena kupitilira apo osakwana 1/3 mtengo wake ndi 1/4 voliyumu.

Pazinthu zomwe zimaphatikizapo kusamutsa kutentha kuchokera kumadzi otentha kupita kumadzi ozizira kudzera pakhoma la chubu, machubu a fin amagwiritsidwa ntchito.Nthawi zambiri, kwa chosinthira kutentha kwa mpweya, komwe kumodzi mwamadzimadzi ndi mpweya kapena mpweya wina, gawo la mpweya wotengera kutentha limakhala lotsika kwambiri, kotero kuti malo owonjezera kutentha kumtunda kapena chowotcha chubu ndichothandiza kwambiri.Mayendedwe amtundu wa chubu chosinthira nthawi zambiri chimakhala chodutsana, komabe, amathanso kuyenda mofananira kapena kubweza.

Zipsepse zimagwiritsidwa ntchito kuonjezera malo ogwira ntchito a kutentha kwa machubu.Kuphatikiza apo, machubu opangidwa ndi zipsepse amagwiritsidwa ntchito ngati mphamvu yotengera kutentha kunja kwa machubu ndi yotsika kwambiri kuposa mkati.M'mawu ena, kutentha anasamutsidwa madzi ndi mpweya, nthunzi kuti mpweya, monga nthunzi kuti mpweya kutentha exchanger, ndi madzimadzi thermic kuti mpweya kutentha exchanger.

Kuchuluka kwa kutentha koteroko kungatheke kumadalira zinthu zitatu - [1] kusiyana kwa kutentha pakati pa madzi awiriwa;[2] kutengera kutentha kokwanira pakati pa madzi aliwonse ndi khoma la chubu;ndi [3] pamwamba pomwe madzimadzi aliwonse amawonekera.

Pokhala ndi chubu chokhala ndi zipsepse m'malo mwake, kumawonjezera kuchuluka kwa kutentha.Machubu opangidwa amawonjezera malo akunja.Izi zimachepetsa kuchuluka kwa machubu ofunikira pakugwiritsa ntchito komwe kumachepetsanso kukula kwa zida zonse ndipo m'kupita kwanthawi kumatha kuchepetsa mtengo wa polojekitiyo.

Finned chubu kutentha exchanger ntchito zosiyanasiyana ntchito, ndi zambiri monga mafakitale kutentha exchanger.Chotenthetsera mpweya ngati koyilo ya evaporator mugawo lowongolera mpweya nthawi zambiri ndi fin chubu exchanger.Wina wodziwika bwino fin chubu air heat exchanger ndi radiator yamagalimoto.Cholinga cha radiator yamagalimoto ndikuziziritsa madzi otentha m'machubu ndi mpweya womwe umadutsa pamtanda.M'malo mwake, koyilo ya mpweya wa evaporator ili ndi cholinga choziziritsa mpweya womwe ukudutsamo.Machubu omwe amapangidwa ku Kainon Boilers amagwiritsa ntchito chitsulo chokwera kwambiri, chitsulo chosapanga dzimbiri, mkuwa, mkuwa, ndi aluminiyamu.Makina athu osinthira ma chubu amapangidwa kuti akwaniritse ntchito yake, kutentha komanso kuthamanga kwamadzi.
