Auto Air Conditioning Refrigeration Pressure Switch

Nthawi zambiri, ma switch switch amayikidwa mufiriji yama air-conditioning system.Ma switch otchinjiriza kupsinjika kumaphatikizapo kusintha kwa kuthamanga kwamphamvu, kusintha kocheperako, kusintha kwakukulu ndi kutsika kophatikizira ndi katatu-boma Pressure switch.Pakali pano, imagwiritsidwa ntchito ngati chosinthira chophatikizira. Mfundo yogwirira ntchito yosinthira mphamvu yamayiko atatu ikufotokozedwa pansipa.

Kusinthana kwamphamvu kumayikidwa pambali yothamanga kwambiri ya air-conditioning system.Pamene kuthamanga kwa refrigerant ndi ≤0.196MPa, popeza mphamvu yothamanga ya diaphragm, kasupe wa butterfly ndi kasupe wapamwamba ndi wamkulu kuposa kuthamanga kwa firiji. , zolumikizira zamphamvu komanso zotsika zimachotsedwa (KUZIMU), kompresa imayima, ndipo chitetezo chochepa kwambiri chimakwaniritsidwa.

Kuthamanga kwa firiji kukafika ku 0.2MPa kapena kupitilira apo, kupanikizika kumeneku kumakhala kokulirapo kuposa kuthamanga kwa kasupe kosinthira, kasupe amapindika, kulumikizana kwapamwamba ndi kutsika kumayatsidwa (ON), ndipo compressor imagwira ntchito bwino.

Kuthamanga kwa refrigerant kukafika ku 3.14MPa kapena kupitilira apo, kudzakhala kwakukulu kuposa mphamvu zotanuka za diaphragm ndi masika a disc. Chimbale kasupe amabwerera kuti aletse kulumikizana kwamphamvu ndi kutsika kwamphamvu ndipo kompresa imayima kuti itetezere kuthamanga kwambiri.

Palinso chosinthira chapakati chomwe chimagwiritsidwa ntchito kwambiri.Pamene kupanikizika kwa refrigerant kuli kwakukulu kuposa 1.77MPa, kupanikizika kumakhala kwakukulu kuposa mphamvu zotanuka za diaphragm, diaphragm imabwerera kumbuyo, ndipo shaft idzakankhidwira mmwamba kuti igwirizane ndi kutembenuka kwa liwiro. Kuthamanga kumatsika mpaka 1.37MPa, diaphragm imabwereranso ku mawonekedwe ake oyambirira, shaft imatsika, kukhudzana kumachotsedwa, ndipo chiwombankhanga chimabwerera ku mawonekedwe ake oyambirira. condensing fan amathamanga pa liwiro lotsika.
