Shacman Truck: Technology Escort, Cool Summer

M’nyengo yotentha kwambiri, dzuwa lili ngati moto. Kwa oyendetsa aShacmanMagalimoto, malo oyendetsa bwino ndikofunikira kwambiri. Luso laShacmanMagalimoto obweretsa kuziziritsa pakutentha kwambiri ndi chifukwa cha mgwirizano wokwanira wa magawo angapo. Pakati pawo, njira yozizirira madzi ndi firiji imagwira ntchito yofunika kwambiri.

Ntchito ya makina oziziritsira madzi ndikuwonetsetsa kuti injini imapeza kuziziritsa kokwanira. Ngakhale mutakumana ndi kutentha kwapamwamba kotheka ndi zowonjezera zowonjezera zowonjezera, dongosololi likhoza kugwirabe ntchito bwino. Monga pachimake cha galimoto yolemera, injini imapanga kutentha kwakukulu pakugwira ntchito. Ngati sichikhoza kuzimitsidwa mu nthawi, idzakhudza ntchito yake ndi moyo wake wonse. Dongosolo lozizirira madzi lili ngati mlonda wokhulupirika, yemwe amaperekeza injini nthawi zonse. Kupyolera mu kayendedwe ka kuzizira kozizira, kutentha kopangidwa ndi injini kumachotsedwa, kuonetsetsa kuti injiniyo imatha kugwira ntchito mokhazikika ngakhale kumalo otentha kwambiri.
Dongosolo la firiji limapanga malo ozizira komanso omasuka oyendetsa galimoto kwa dalaivala. Choyamba, kompresa ali ngati mtima wamphamvu. Moyendetsedwa ndi injini, imakanikiza firiji mosalekeza kuti ikhale yotentha kwambiri komanso mpweya wothamanga kwambiri, zomwe zimapereka mphamvu mosalekeza kwa dongosolo lonse la firiji. Zimagwira ntchito ndi mphamvu zake zonse kufinya firiji ya mpweya kuti ikhale yoyenera, ndikuyika maziko a ndondomeko yotsatirira firiji.
Condenser ili ngati mlonda wodekha, yemwe ali ndi udindo waukulu wochotsa kutentha. Pambuyo pa kutentha kwambiri komanso mpweya wothamanga kwambiri wotuluka mu kompresa umalowa mu condenser, kupyolera mu kutentha kutentha ndi mpweya wakunja, kutentha kumatayika, ndipo refrigerant imazizira pang'onopang'ono ndikulowa mumadzimadzi. Kuchita kwake bwino kwa kutentha kwa kutentha kumatsimikizira kuti firiji imatha kuzizira mofulumira ndikukonzekera ulendo wotsatira wa firiji.
Valavu yowonjezera ili ngati chowongolera cholondola. Malingana ndi zosowa za kutentha kwa mkati, zimasintha molondola kutuluka kwa firiji. Ikhoza kugwedezeka ndikuchepetsa kupanikizika kwa refrigerant yamadzimadzi yothamanga kwambiri kuti ikhale yotentha komanso yotsika kwambiri, kukonzekera kulowa mu evaporator. Kupyolera mu kusintha kwabwino kwa firiji, valavu yowonjezera imatsimikizira kuti firiji ikhoza kupereka mphamvu yoyenera yozizira pansi pazikhalidwe zosiyanasiyana zogwirira ntchito.
Evaporator ndiye gawo lomaliza lokwaniritsa mawonekedwe a firiji. Refrigerant yotsika kwambiri komanso yotsika kwambiri imatenga kutentha mkati mwagalimoto mu evaporator ndikutuluka mwachangu, kuchepetsa kutentha mkati mwagalimoto. Evaporator idapangidwa mwanzeru kuti iwonjezere malo olumikizana ndi mpweya ndikuwongolera kusinthana kwa kutentha. Pansi pa zomwe zimakupiza, mpweya wotentha mkati mwa galimotoyo umadutsa mosalekeza kudzera mu evaporator ndipo umakhazikika ndikubwezeretsedwanso mgalimoto, motero kupanga malo ozizira komanso omasuka oyendetsa galimoto.
Fani ndi gawo lofunika kwambiri la firiji. Imafulumizitsa kusinthana kwa kutentha pakati pa condenser ndi evaporator ndi mpweya wakunja kupyolera mu kusuntha kokakamiza. Kumbali ya condenser, fani imawomba mpweya wozizira wakunja kupita ku condenser kuthandiza refrigerant kuchotsa kutentha; kumbali ya evaporator, fani imawomba mpweya woziziritsa m'galimoto kuti ukhale wabwino.
Magawo awa aShacmanMagalimoto amagwirira ntchito limodzi kuti apange firiji yabwino. M’nyengo yotentha, amagwira ntchito limodzi kuti abweretse kuzizira ndi chitonthozo kwa dalaivala. Kaya mumsewu waukulu wamayendedwe atali kapena pamalo ogwirira ntchito ovuta,ShacmanMagalimoto amatha kukhala othandizana nawo odalirika kwa madalaivala omwe ali ndi magwiridwe antchito abwino kwambiri a firiji komanso makina oziziritsira madzi okhazikika. Ndi mgwirizano wawo mwakachetechete, amatanthauzira mphamvu yaukadaulo ndi chisamaliro kwa oyendetsa, kupangitsa ulendo uliwonse woyendetsa galimoto kukhala wosangalatsa komanso wolimbikitsa. M'tsogolo chitukuko, amakhulupirira kutiShacmanMagalimoto apitiliza kupanga zatsopano ndikupangitsa madalaivala kukhala oyendetsa bwino kwambiri.
