I-Auto Air Conditioning Refrigeration Pressure Switch

Incazelo emfushane:

I-pressure switch ifakwe ohlangothini lwe-high-pressure yesistimu ye-air-conditioning.Lapho ukucindezela kwesiqandisi kungu-≤0.196MPa, njengoba amandla anwebekayo we-diaphragm, isiphethu sovemvane kanye nesiphethu esiphezulu kukhulu kunokucindezela kwesiqandisi. , abathintwayo bengcindezi ephezulu nephansi bayanqanyulwa (OFF), i-compressor iyama, futhi ukuvikelwa kokucindezela okuphansi kuyabonakala.

Lapho ingcindezi yefriji ifinyelela ku-0.2MPa noma ngaphezulu, lokhu kucindezela kuphakeme kunokucindezela kwentwasahlobo komshini, isiphethu sizogoba, othintana nabo abaphezulu nabaphansi bavuliwe (ON), futhi i-compressor isebenza ngokujwayelekile.

Isimiso Sokusebenza

Ngokuvamile, amaswishi okucindezela afakwa ezinhlelweni zesiqandisi se-air-conditioning yemoto.Amaswishi okuvikela ukucindezela ahlanganisa ukushintsha kokucindezela okukhulu, ukushintsha komfutho ophansi, ukushintsha kokuhlanganiswa komfutho ophansi nophezulu kanye nokuthathu-isimo I-pressure switch.Okwamanje, ivamise ukusetshenziswa njengenhlanganisela ye-pressure switch. Umgomo wokusebenza wokushintsha kwengcindezi yezifunda ezintathu wethulwa ngezansi.

Uma ingcindezi yesiqandisi ifinyelela ku-3.14MPa noma ngaphezulu, izoba mkhulu kunamandla anwebekayo we-diaphragm kanye ne-disc spring. I-disc spring iyahlehla ukuze inqamule abathintwayo abaphezulu nabaphansi futhi i-compressor iyama ukuze ithole ukuvikeleka kwengcindezi ephezulu.

Kukhona futhi umshini wokushintsha umfutho ophakathi nendawo ovame ukusetshenziswa.Lapho ingcindezi yesiqandisi ingaphezu kuka-1.77MPa, ingcindezi inkulu kunamandla anwebekayo we-diaphragm, i-diaphragm izohlehla, futhi i-shaft izophushwa phezulu ukuze kuxhunywe othintana naye wokuguqula isivinini. ye-condenser fan (noma i-radiator fan), futhi ifeni izogijima ngesivinini esiphezulu ukuze ifinyelele ukuvikeleka kwengcindezi.Lapho ukucindezela kwehla ku-1.37MPa, i-diaphragm ibuyela esimweni sayo sokuqala, i-shaft iyawa, ukuthintana kuyanqanyulwa, futhi I-condensing fan igijima ngesivinini esiphansi.
