Valavu yowonjezera - chinthu chofunikira kwambiri mu dongosolo loziziritsira.
Vavu yowonjezera ndi gawo lofunika kwambiri la makina oziziritsira, omwe nthawi zambiri amaikidwa pakati pa silinda yosungira madzi ndi evaporator. Vavu yowonjezera imapangitsa kuti firiji yamadzimadzi ya kutentha kwapakati ndi kuthamanga kwambiri ikhale kutentha kochepa komanso nthunzi yonyowa yotsika kudzera mu throttling yake, kenako refrigerant imayamwa kutentha mu evaporator kuti ikwaniritse zotsatira za firiji. Vavu yowonjezera imayang'anira kuyenda kwa valavu kudzera mu kusintha kwa kutentha kwambiri kumapeto kwa evaporator kuti apewe kugwiritsa ntchito mokwanira malo a evaporator ndi vuto la kugwedezeka kwa silinda.
Chikwama chowunikira kutentha
Refrigerant yomwe ili mu thumba lozindikira kutentha ili mu mkhalidwe wa gasi-madzimadzi komanso kukhuta, ndipo gawo ili la refrigerant silimalumikizidwa ndi refrigerant mu dongosolo. Nthawi zambiri limalumikizidwa ndi chitoliro chotulutsira evaporator, kukhudzana kwambiri ndi chitoliro kuti mumve kutentha kwa nthunzi ya evaporator, chifukwa refrigerant yake yamkati imakhala yodzaza, kotero malinga ndi kutentha komwe kutentha kumasamutsa, kuthamanga kwa thupi la valavu kumayikidwa.
Chubu choyezera
Malekezero ena a chubu choyezera amalumikizidwa ndi chotulutsira mpweya chochokera mu evaporator kutali pang'ono ndi envelopu ya kutentha, ndipo amalumikizidwa mwachindunji ndi thupi la valavu kudzera mu chubu cha capillary. Ntchito yake ndikusamutsa kupanikizika kwenikweni kwa chotulutsira mpweya chochokera mu evaporator kupita ku thupi la valavu. Pali ma diaphragm awiri m'thupi la valavu, ndipo diaphragm imakwera mmwamba pansi pa mphamvu ya kupanikizika kuti ichepetse kuyenda kwa refrigerant kudzera mu valavu yowonjezera ndikufunafuna kukhazikika mu mphamvu.
Chiweruzo cha khalidwe
Mkhalidwe wabwino kwambiri wogwirira ntchito wa valavu yokulitsa uyenera kukhala kusintha malo otseguka nthawi yeniyeni ndikuwongolera kuchuluka kwa madzi ndi kusintha kwa katundu wa evaporator. Komabe, kwenikweni, chifukwa cha kutentha komwe kumamveka ndi envelopu yotenthetsera kutentha, yankho la valavu yokulitsa nthawi zonse limakhala locheperako pang'ono. Ngati tijambula chithunzi cha nthawi ya valavu yokulitsa, tidzapeza kuti si yokhota yosalala, koma mzere wozungulira. Ubwino wa valavu yokulitsa umawonekera mu kukula kwa ma curve ndi ma turn, ndipo kukula kwa valavu kukakhala kwakukulu, kumachita pang'onopang'ono kwa valavu ndipo khalidwe lake limakhala loipa kwambiri.
Valavu yowonjezera mpweya woziziritsa mpweya m'galimoto yasweka
01 Valavu yowonjezera yatsegulidwa yayikulu kwambiri
Kutsegula valavu yokulitsa mpweya wa galimoto yokhala ndi mpweya waukulu kwambiri kungayambitse kuchepa kwa mphamvu yozizira. Ntchito yayikulu ya valavu yokulitsa ndikulamulira kayendedwe ka firiji mu evaporator kuti mphamvu yochepa mu evaporator ikhalebe. Pamene valavu yokulitsa yatsegulidwa kwambiri, kayendedwe ka refrigerant kamawonjezeka, zomwe zingayambitse mphamvu yochepa mu evaporator kukhala yokwera kwambiri. Izi zimapangitsa kuti refrigerant isanduke madzi msanga mu evaporator, zomwe zimachepetsa mphamvu yoyamwa kutentha mu evaporator. Chifukwa chake, mphamvu yozizira ya mpweya wa galimoto idzachepa kwambiri.
02 Kuziziritsa ndi kutentha sikwabwino
Kuwonongeka kwa valavu yokulitsa mpweya wa galimoto kudzapangitsa kuti mpweya woziziritsa ndi kutentha ukhale woipa. Vavu yokulitsa imagwira ntchito poyendetsa kayendedwe ka refrigerant mu makina oziziritsira mpweya. Vavu yokulitsa ikawonongeka, kayendedwe ka refrigerant kangakhale kosakhazikika kapena kwakukulu kwambiri, zomwe zimakhudza kuzizira ndi kutentha. Kagwiridwe kake ndi aka: mu makina oziziritsira, kutentha mkati mwa galimoto sikungachepe kufika pa mtengo wokhazikika; Mu makina otenthetsera, kutentha mkati mwa galimoto sikungakwere kufika pa mtengo wokhazikika. Kuphatikiza apo, kuwonongeka kwa valavu yokulitsa kungayambitsenso kuwonongeka kwa zigawo zina za makina oziziritsira mpweya, zomwe zimakhudzanso kuzizira ndi kutentha. Chifukwa chake, kutentha kapena kutentha kwa mpweya woziziritsira ukapezeka kuti ndi woipa, valavu yokulitsa iyenera kuyang'aniridwa nthawi yake kuti ione ngati yawonongeka.
03 Valavu yokulitsa ndi yaying'ono kwambiri kapena yolakwika
Kutsegula valavu yokulitsa ndi yaying'ono kwambiri kapena kusagwira ntchito bwino kungayambitse mavuto mu makina oziziritsira mpweya m'galimoto. Ngati valavu yokulitsa ndi yaying'ono kwambiri, kuyenda kwa firiji kumakhala kochepa, zomwe zimapangitsa kuti mphamvu yozizira ya makina oziziritsira mpweya ichepe. Kuphatikiza apo, chifukwa firijiyo sikuyenda bwino mu evaporator, ingayambitse evaporator kuzizira kapena kuzizira pamwamba. Ngati valavu yokulitsa yalephera kwathunthu, makina oziziritsira mpweya sangazizire kapena kutentha konse. Pankhaniyi, muyenera kusintha valavu yokulitsa mwachangu momwe mungathere kuti mubwezeretse momwe makina oziziritsira mpweya amagwirira ntchito.
04 Musapumule kapena kugona mgalimoto yokhala ndi mpweya woziziritsa kwa nthawi yayitali
Si nzeru kusagona kapena kugona kwa nthawi yayitali mgalimoto muli mpweya woziziritsa, makamaka ngati pali vuto ndi valavu yokulitsa mpweya wa galimoto. Mavalavu okulitsa ndi zinthu zofunika kwambiri m'makina oziziritsira mpweya a magalimoto ndipo ali ndi udindo wowongolera kuyenda ndi kuthamanga kwa mpweya woziziritsa. Vavu yokulitsa ikawonongeka, mphamvu yoziziritsira imatha kuchepetsedwa kapena kulephera kwathunthu. Pa kutentha kwambiri, kukhala pamalo otere kwa nthawi yayitali kungayambitse kutaya madzi m'thupi ndi kutopa, komanso ngakhale zinthu zomwe zingawopseze moyo. Chifukwa chake, ngati mupeza vuto ndi valavu yokulitsa mpweya wa galimoto, ndi bwino kupewa kupuma kapena kugona kwa nthawi yayitali mgalimoto kuti muwonetsetse kuti muli otetezeka komanso omasuka.
Ngati mukufuna kudziwa zambiri, pitirizani kuwerenga nkhani zina patsamba lino!
Chonde tiimbireni foni ngati mukufuna zinthu zotere.
Malingaliro a kampani Zhuo Meng Shanghai Auto Co., Ltd.yadzipereka kugulitsa zida zamagalimoto za MG&MAUXS zomwe zalandiridwakugula.
