Vavu yowonjezera - chinthu chofunika kwambiri mu firiji dongosolo.
Valavu yowonjezera ndi gawo lofunika kwambiri la firiji, yomwe nthawi zambiri imayikidwa pakati pa silinda yosungiramo madzi ndi evaporator. The valavu kutambasuka zimapangitsa madzi refrigerant wa sing'anga kutentha ndi kuthamanga kwambiri kukhala otsika kutentha ndi otsika kuthamanga chonyowa nthunzi kudzera throttling ake, ndiyeno refrigerant zimatenga kutentha mu evaporator tikwaniritse refrigeration kwenikweni. Valavu yowonjezera imayendetsa kayendedwe ka valve kupyolera mu kusintha kwa kutentha kwapamwamba kumapeto kwa evaporator kuti ateteze kusagwiritsidwa ntchito kosakwanira kwa dera la evaporator ndi cylinder kugogoda chodabwitsa.
Chikwama chozindikira kutentha
The refrigerant mlandu mu thumba sensing kutentha ali mu chikhalidwe cha gasi-zamadzimadzi Equilibrity ndi machulukitsidwe, ndipo mbali iyi ya refrigerant si analankhulana ndi refrigerant mu dongosolo. Nthawi zambiri womangidwa ndi evaporator kubwereketsa chitoliro, pafupi kukhudzana ndi chitoliro kumva evaporator kubwereketsa kutentha nthunzi kutentha, chifukwa refrigerant wake mkati zimakhutitsidwa, choncho malinga ndi kutentha kutengerapo kutentha machulukitsidwe boma kuthamanga kwa valavu thupi.
Equalizing chubu
Mapeto amodzi a chubu chowongolera amalumikizidwa ndi chotulutsa evaporator pang'ono kutali ndi envulopu ya kutentha, ndipo imalumikizidwa mwachindunji ndi thupi la valve kudzera mu chubu cha capillary. Ntchitoyi ndikusamutsa kukakamiza kwenikweni kwa chotulutsa evaporator kupita ku thupi la valve. Pali ma diaphragms awiri m'thupi la valve, ndipo diaphragm imasunthira mmwamba pansi pa kukakamizidwa kuti muchepetse kuthamanga kwa refrigerant kudzera mu valve yowonjezera ndikuyang'ana bwino mu mphamvu.
Kuweruza kwabwino
Njira yabwino yogwiritsira ntchito valve yowonjezera iyenera kukhala kusintha kutsegulira mu nthawi yeniyeni ndikuwongolera kuthamanga kwa kuthamanga ndi kusintha kwa evaporator katundu. Komabe, kwenikweni, chifukwa cha hysteresis ya kutentha komwe kumamveka ndi envelopu yotentha mu kutentha kwa kutentha, kuyankha kwa valve yowonjezera nthawi zonse kumakhala theka la kugunda pang'onopang'ono. Ngati tijambula chithunzi cha nthawi ya valve yowonjezera, tidzapeza kuti si njira yosalala, koma mzere wa zigzag. Ubwino wa valavu yowonjezera ukuwonekera mu matalikidwe a kupotoza ndi kutembenuka, ndipo kukula kwa matalikidwe, pang'onopang'ono kachitidwe ka valve ndi khalidwe loipa kwambiri.
Valavu yowonjezera mpweya wa galimoto yathyoka
01 Valavu yowonjezera imatsegulidwa yayikulu kwambiri
Kutsegula valavu yokulitsa ya makina oziziritsa mpweya wamgalimoto yokulirapo kwambiri kungapangitse kuti kuziziritsa kuchepe. Ntchito yaikulu ya valavu yowonjezera ndikuwongolera kutuluka kwa refrigerant mu evaporator kuti ikhalebe yotsika kwambiri mu evaporator. Pamene valavu yowonjezera imatsegulidwa kwambiri, kutuluka kwa firiji kumawonjezeka, zomwe zingayambitse kutsika kochepa mu evaporator kukhala kwakukulu. Izi zimapangitsa kuti refrigerant isinthe kukhala madzi nthawi isanakwane mu evaporator, zomwe zimachepetsa kuyamwa kwa kutentha mu evaporator. Chifukwa chake, kuziziritsa kwa mpweya wamagalimoto kumachepetsedwa kwambiri.
02 Kuzizira ndi kutentha sikwabwino
Kuwonongeka kwa valavu yowonjezera ya mpweya wamagalimoto kumapangitsa kuti pakhale kuzizirira bwino komanso kutentha. Valavu yowonjezera imagwira ntchito pakuwongolera kuyenda kwa refrigerant mu air conditioning system. Pamene valve yowonjezera yawonongeka, kutuluka kwa refrigerant kungakhale kosakhazikika kapena kwakukulu kwambiri, motero kumakhudza kuzizira ndi kutentha. Ntchito yeniyeni ndi: mufiriji, kutentha mkati mwa galimoto sikungachepetse mtengo wokhazikitsidwa; Potentha, kutentha mkati mwa galimoto sikungakwere kufika pamtengo wokhazikitsidwa. Kuonjezera apo, kuwonongeka kwa valve yowonjezera kungayambitsenso kuwonongeka kwa zigawo zina za mpweya wabwino, zomwe zimakhudzanso kuzizira ndi kutentha. Choncho, pamene kuzizira kapena kutentha kwa mpweya wozizira kumakhala kovutirapo, valavu yowonjezera iyenera kufufuzidwa mu nthawi kuti muwone ngati yawonongeka.
03 Valavu yowonjezera ndiyochepa kwambiri kapena yolakwika
Kutsegula valavu yowonjezera yaying'ono kwambiri kapena yosagwira ntchito kungayambitse mavuto mu makina oyendetsa mpweya wa galimoto. Pamene valavu yowonjezera imatsegulidwa yaying'ono kwambiri, kutuluka kwa refrigerant kumakhala kochepa, zomwe zimapangitsa kuti kuzizira kwa mpweya wa mpweya kuchepe. Kuonjezera apo, chifukwa firiji sikuyenda mokwanira mu evaporator, ikhoza kuchititsa kuti evaporator iundane kapena kuzizira pamwamba. Vavu yowonjezera ikalephera kwathunthu, makina owongolera mpweya sangakhale ozizira kapena kutentha konse. Pankhaniyi, muyenera kusintha valavu yowonjezera mwamsanga kuti mubwezeretsenso chikhalidwe chogwira ntchito cha mpweya wabwino.
04 Osapumula kapena kugona m'galimoto ndi zoziziritsa kukhosi kwa nthawi yayitali
Sichinthu chanzeru kuti musapume kapena kugona kwa nthawi yayitali m'galimoto ndi mpweya, makamaka ngati pali vuto ndi valavu yowonjezera ya mpweya wa galimoto. Mavavu okulitsa ndi zigawo zazikulu zamakina owongolera mpweya wamagalimoto ndipo ali ndi udindo wowongolera kuyenda kwa refrigerant ndi kuthamanga. Vavu yowonjezera ikawonongeka, kuzizira kumatha kuchepetsedwa kapena kulephera kwathunthu. Kutentha kwambiri, kutetezedwa kwa nthawi yayitali kumalo otere kungayambitse kutaya madzi m'thupi ndi kutopa, komanso ngakhale kuopseza moyo. Choncho, ngati mutapeza vuto ndi valavu yowonjezera ya mpweya wa galimoto, ndi bwino kupewa kupuma kapena kugona kwa nthawi yaitali m'galimoto kuti muteteze chitetezo ndi chitonthozo.
Ngati mukufuna kudziwa zambiri, pitilizani kuwerenga zolemba zina patsamba lino!
Chonde tiyimbireni ngati mukufuna zinthu zotere.
