Auto Air Conditioning Refrigeration Pressure Switch

Kazhinji, kushandiswa kwemagetsi kunoiswa mumotokari air-conditioning firiji masisitimu.Kudzivirirwa kwedziviriro kunosanganisira high pressure pressure switch, low pressure pressure switch, high and low pressure combination switch and three-state pressure switch.Parizvino, inowanzoshandiswa semusanganiswa wekumanikidza switch. Nheyo yekushanda yematatu-state pressure switch inounzwa pazasi.

Shanduko yekumanikidza inoiswa padivi repamusoro-kudzvanya kwemhepo-conditioning system.Kana refrigerant pressure iri ≤0.196MPa, sezvo elastic force ye diaphragm, butterfly spring uye chepamusoro chitubu chikuru kupfuura kumanikidza kwefiriji. , iyo yakakwira uye yakaderera kudzvanywa mabatirwo anodimburwa (OFF), iyo compressor inomira, uye yakaderera chengetedzo yekudzivirira inowanikwa.

Kana iyo refrigerant pressure inosvika 0.2MPa kana kupfuura, iyi dzvinyiriro yakakwira kupfuura kudzvanywa kwechitubu chekuchinja, chitubu chinokotama, iyo yakakwira uye yakaderera kudzvanywa maconta anovhurwa (ON), uye compressor inoshanda zvakajairika.

Kana iyo refrigerant pressure inosvika 3.14MPa kana kupfuura, ichave yakakura kudarika elastic force ye diaphragm uye disc spring. Iyo disc chitubu inodzokera kumashure kuti ibvise iyo yakakwira uye yakaderera kudzvanywa mabatiki uye iyo compressor inomira kuti iwane yakakwira kuchengetedzwa.

Kune zvakare inowanzo shandiswa yepakati pressure switch.Kana refrigerant pressure yakakura kudarika 1.77MPa, pressure yakakura kudarika elastic force ye diaphragm, diaphragm inodzokera kumashure, uye shaft ichasundidzirwa kumusoro kuti ubatanidze speed conversion contact. ye condenser fan (kana radiator fan), uye fan inomhanya nekumhanya kukuru kuti iwane kuchengetedzwa kwekumanikidza. Kana kudzvanywa kwadonha kusvika ku 1.37MPa, diaphragm inodzokera kune yayo yepakutanga chimiro, shaft inodonha, kubata kunobviswa, uye iyo condensing fan inomhanya nekumhanya kwakaderera.
