Kodi valavu mu makina opopera mpweya woziziritsa magalimoto ndi chiyani?
Chimodzi mwa zigawo zazikulu za makina opopera mpweya woziziritsa magalimoto ndi valavu yowongolera njira zinayi (yomwe imadziwikanso kuti valavu ya njira zinayi), yomwe ndi chipangizo chofunikira kwambiri chosinthira pakati pa njira zoziziritsira ndi zotenthetsera.
Ntchito ndi kapangidwe ka valavu ya njira zinayi
Valavu ya njira zinayi imalamulira kayendetsedwe ka chotsetsereka kudzera mu coil yamagetsi kuti isinthe njira yoyendera ya refrigerant.
Youdaoplaceholder0 Njira yoziziritsira : Chotsekeracho chimasunthira kumanzere, kulumikiza chotulutsira compressor ku chosinthira kutentha chamkati (evaporator) ndi cholowera ku chosinthira kutentha chakunja (condenser), ndi chosinthira kutentha chakunja chomwe chimagwira ntchito ngati chotenthetsera kutentha.
Youdaoplaceholder0 Kutentha mode : chotsetsereka chimasunthira kumanja. Chotulutsira compressor chimalumikizidwa ku chosinthira kutentha chakunja, ndipo cholowera chimalumikizidwa ku chosinthira kutentha chamkati. Chosinthira kutentha chamkati chimagwira ntchito ngati chotenthetsera kutulutsa kutentha, pomwe chosinthira kutentha chakunja chimatenga kutentha kozungulira.
Zinthu zazikulu zaukadaulo
Njira yoyendetsera mpweya mufiriji imayendetsedwa ndi valavu yowongolera yamagetsi kuti ikwaniritse kusintha kwachangu kwa mode.
Pogwiritsa ntchito kutentha kwa reverse cycle (kugwiritsa ntchito mphamvu zamagetsi zochepa kuti mutumize kutentha kwakukulu), mphamvu yotenthetsera nthawi yozizira ikhoza kuwonjezeka.
Iyenera kugwira ntchito mogwirizana ndi zinthu monga ma compressor amagetsi ndi ma valve okulitsa amagetsi kuti ipange dongosolo lonse la pampu yotenthetsera.
Ogulitsa akuluakulu apakhomo ndi Sanhua Intelligent Control, Yilun Co., Ltd. ndi mabizinesi ena.
Valavu ya makina opopera mpweya woziziritsa magalimoto (nthawi zambiri imatanthauza valavu ya njira zinayi) ndi gawo lofunikira kwambiri posintha pakati pa njira zoziziritsira ndi zotenthetsera, kukwaniritsa njira ziwiri zogwirira ntchito posintha njira yoyendera ya refrigerant.
Mufiriji
Valavu ya njira zinayi ikayatsidwa, imasinthira ku AD yolumikizidwa ndi BC yolumikizidwa. Refrigerant imazungulira kudzera mu compressor → condenser → expansion valve → evaporator → compressor kuti izizire mkati mwa galimoto.
Kutentha
Valavu ya njira zinayi ikachotsedwa mphamvu, imasinthira ku AD yolumikizidwa ndi BC yolumikizidwa. Refrigerant imazungulira kudzera mu compressor → cooler → expansion valve → condenser → compressor, ndikutenthetsa mpweya mkati mwa galimotoyo poyamwa kutentha kuchokera kunja.
Vavu iyi ilinso ndi ntchito yoteteza compressor: imatseka yokha valavu pamene kuthamanga kwa payipi sikuli bwino kuti compressor isachuluke kwambiri komanso kuwonongeka.
Kulephera kwa ma valve mu makina opopera mpweya woziziritsa magalimoto kungawonekere ngati zizindikiro zotsatirazi:
Mphamvu yozizira/yotenthetsera yatsika
Pamene ma valve a makina opopera kutentha (monga ma valve a njira zinayi kapena ma valve a solenoid) alephera kugwira ntchito bwino, izi zingayambitse kuyenda kosazolowereka kwa firiji, zomwe zimakhudza mwachindunji kuziziritsa kapena kutentha bwino. Mwachitsanzo, valavu ya njira zinayi yomwe yakhazikika ingayambitse kuchepa kwa kutentha kopitilira katatu, pomwe valavu ya solenoid ikalephera kugwira ntchito bwino ingayambitse kuyenda kosakhazikika kwa mpweya wozizira kapena kugwira ntchito kosazolowereka kwa compressor.
Njira yodzitetezera yakhazikitsidwa
Zolakwika zingayambitse njira yodzitetezera ya makina oziziritsira mpweya, monga compressor kuzimitsa yokha chifukwa cha kupanikizika kwambiri, kapena makinawo kuzimitsa okha chifukwa cha kutentha kwambiri.
Phokoso losazolowereka komanso kuchuluka kwa mphamvu zomwe zimagwiritsidwa ntchito
Ngati chowongolera ma valavu sichili bwino, mavuto monga phokoso losazolowereka kuchokera ku compressor ndi mphamvu yochulukirapo angachitike, zomwe zingachititse kuti mphamvu igwiritsidwe ntchito kwambiri (monga kuchepetsa magalimoto atsopano amagetsi) kapena kuchepa kwa mphamvu yozizira kwa batri.
Malangizo okonza
Ndikofunikira kuyang'ana kwambiri kulumikizana kwa magetsi, kutuluka kwa mpweya mufiriji kapena mavuto okhudzana ndi kutsekeka kwa ma valavu. Ngati valavu ya solenoid ili ndi vuto, ndikofunikira kuwona ngati valavu yakhazikika kapena yasungunuka. Ngati kuli kofunikira, valavu iyenera kusinthidwa.
Kuwonongeka kwa valavu mu makina opopera mpweya woziziritsa galimoto kungayambitse zotsatira zosazolowereka zoziziritsa/zotenthetsera. Zizindikiro zenizeni ndi malingaliro okonza ndi awa:
Zizindikiro zofala za zolakwika
Kuzizira/kutentha koyipa : Ngati valavu yatsekeka kapena kuwonongeka, ingayambitse kuyenda kosazolowereka kwa firiji, zomwe zimakhudza kuyenda bwino kwa dongosololi ndipo zimapangitsa kuti kuzizira ndi kutentha kusatuluke mokwanira.
Youdaoplaceholder0 nthawi zina imakhala yozizira ndipo nthawi zina imakhala yotentha : Pamene njira yowongolera ma valve si yachilendo, kuzizira/kutentha kumatha kuchitika nthawi ndi nthawi. Mwachitsanzo, ikhoza kubwezeretsedwa kwakanthawi mutatseka switch ya AC ndikuyambiranso.
Youdaoplaceholder0 Kusokonezeka kwa kuthamanga kwa magazi: Kulephera kwa valavu kungayambitse kusinthasintha kwa kuthamanga kwa magazi kumbali ya kuthamanga kwambiri komanso kotsika, zomwe zimapangitsa kuti deta isayende bwino.
Malangizo okonza
Youdaoplaceholder0 Yang'anani momwe valavu ilili: Ngati mukukayikira kuti pali vuto la valavu, deta ya kuthamanga ndi momwe singano ya valavu imayendera zitha kuzindikirika ndi zida zaukadaulo kuti zitsimikizire ngati yakhazikika kapena yawonongeka.
Youdaoplaceholder0 Sinthanitsani magawo : Ngati ndi valavu yamakina (monga valavu yosinthasintha yosinthika), fakitale yoyambirira kapena magawo ogwirizana nayo ayenera kusinthidwa (mwachitsanzo, valavu yosinthasintha yosinthika iyenera kusinthidwa ya Focus model); Ngati ndi valavu yamagetsi, gawo lolowa m'malo logwirizana ndi logic yowongolera liyenera kufananizidwa.
Youdaoplaceholder0 Kufananiza ndi kukonza zolakwika za dongosolo : Pambuyo posintha, magawo a kuthamanga kwa dongosolo ayenera kubwezeretsedwanso kuti zitsimikizire kuti mphamvu ya refrigerant ikugwirizana ndi valavu.
Ndikofunikira kulankhulana ndi bungwe losamalira akatswiri kuti mudziwe chomwe chayambitsa vutoli kuti mupewe kuwonongeka kwachiwiri komwe kumachitika chifukwa chodzisokoneza.
Ngati mukufuna kudziwa zambiri, pitirizani kuwerenga nkhani zina patsamba lino!
Chonde tiimbireni foni ngati mukufuna zinthu zotere.
