Kusamalira zofukula m'chilimwe, pewani kulakwitsa kwa kutentha kwakukulu - radiator

Kukonza zofukula m'chilimwe, pewani kulakwitsa kwa kutentha kwakukulu -radiator

Malo ogwirira ntchito ofukula ndi ovuta, ndipo kutentha kwakukulu kungakhudze magwiridwe antchito a makina.Komabe, kutentha kukakhala koopsa, kungakhudzenso moyo wautumiki wa makinawo.Kutentha kogwira ntchito ndikofunikira kwa okumba.Kapangidwe ka kutentha kwa zofukula zimatenga motere:

Kutentha kopangidwa ndi 01 injini kuyaka mafuta;

02 Mafuta a Hydraulic amatulutsa kutentha komwe kumatha kusinthidwa kukhala mphamvu yamagetsi mu hydraulic system;

03 Kutentha kwamphamvu komwe kumapangidwa ndi ma hydraulic transmission ndi ma transmission ena pakuyenda;

04 Kutentha kwa dzuwa.

Pakati pa magwero akuluakulu otentha a zofukula, kuyaka kwa injini kumakhala pafupifupi 73%, mphamvu ya hydraulic ndi kufalitsa kumapanga pafupifupi 25%, ndipo kuwala kwa dzuwa kumapanga pafupifupi 2%.

Pamene chilimwe chotentha chikuyandikira, tiyeni tidziwe ma radiator akuluakulu pa zofukula:

① Reyeta yoziziritsa

Ntchito: Powongolera kutentha kwa antifreeze ya injini yozizirira kudzera mu mpweya, injini imatha kugwira ntchito mkati mwa kutentha koyenera pansi pamikhalidwe yosiyanasiyana yogwirira ntchito, kupewa kutenthedwa kapena kuzizira.

Zotsatira zake: Ngati kutenthedwa kukuchitika, zigawo zosuntha za injini zidzakula chifukwa cha kutentha kwakukulu, zomwe zimayambitsa kuwonongeka kwa chilolezo chawo chogonana, zomwe zimapangitsa kulephera ndi kupanikizana pa kutentha kwakukulu;Mphamvu yamakina ya gawo lililonse imachepetsedwa kapena kuonongeka chifukwa cha kutentha kwakukulu;Panthawi yogwiritsira ntchito injini, kutentha kwakukulu kungayambitse kuchepa kwa voliyumu yoyamwa komanso ngakhale kuyaka kwachilendo, zomwe zimapangitsa kuchepa kwa mphamvu ya injini ndi zizindikiro zachuma.Choncho, injini sangathe kugwira ntchito pa kutentha kwambiri.Ngati kuzizira kwambiri, kuwonongeka kwa kutentha kumawonjezeka, kukhuthala kwa mafuta kumakhala kwakukulu, ndipo kutayika kwamphamvu kwamphamvu kumakhala kwakukulu, zomwe zimapangitsa kuchepa kwa mphamvu ya injini ndi zizindikiro zachuma.Choncho, injini sangathe kugwira ntchito pansi pa mikhalidwe ya subcooled.

② radiator yamafuta a hydraulic

Ntchito: Pogwiritsa ntchito mpweya, kutentha kwa mafuta a hydraulic kumatha kukhala koyenera mkati mwa nthawi yogwira ntchito mosalekeza, ndipo makina a hydraulic amatha kutentha mofulumira akagwiritsidwa ntchito kumalo ozizira, kufika pa kutentha kwapakati pa kutentha kwa mafuta a hydraulic.

Zotsatira: Kugwiritsa ntchito ma hydraulic system pa kutentha kwambiri kumatha kupangitsa kuti mafuta a hydraulic awonongeke, kutulutsa zotsalira zamafuta, ndikupangitsa kuti zida za hydraulic zichotsedwe, zomwe zingayambitse kutsekeka kwa doko la throttle.Kutentha kumawonjezeka, kukhuthala ndi kutsekemera kwa mafuta a hydraulic kudzachepa, zomwe zidzafupikitsa kwambiri moyo wogwira ntchito wa zigawo za hydraulic.Zisindikizo, zodzaza, ma hoses, zosefera zamafuta, ndi zinthu zina zamakina a hydraulic zimakhala ndi kutentha kwina kogwira ntchito.Kutentha kwambiri kwamafuta mumafuta a hydraulic kumatha kufulumizitsa ukalamba wawo komanso kulephera kwawo.Chifukwa chake, ndikofunikira kugwiritsa ntchito ma hydraulic system pa kutentha komwe kumayikidwa.

③ Intercooler

Ntchito: Kuziziritsa mpweya wotentha kwambiri pambuyo pa turbocharging mpaka kutentha kochepa kwambiri kudzera mumlengalenga kuti mukwaniritse zofunikira za malamulo otulutsa mpweya, ndikuwongolera mphamvu ya injini ndi chuma.

Zokhudza: Turbocharger imayendetsedwa ndi mpweya wotulutsa injini, ndipo kutentha kwa injini kumafika madigiri masauzande.Kutentha kumasamutsidwa ku mbali ya turbocharger, zomwe zimapangitsa kuti kutentha kuchuluke.Mpweya woponderezedwa kudzera mu turbocharger umapangitsanso kuti kutentha kuchuluke.Kutentha kwakukulu kwa mpweya kungayambitse kuphulika kwa injini, zomwe zimabweretsa zotsatira zoipa monga kuchepa kwa turbocharging ndi moyo waufupi wa injini.

④ mpweya condenser

Ntchito: Gasi wozizira kwambiri komanso wothamanga kwambiri kuchokera ku kompresa amakakamizika kusungunuka ndikukhala madzi otentha kwambiri komanso opanikizika kwambiri chifukwa chozizira ndi fani ya radiator kapena fani ya condenser.
