Pressure Switch For Refrigeration System

Pambuyo podzazidwa, firiji imalowa mu chipolopolo cha aluminiyamu (ndiko kuti, mkati mwa chosinthira) kupyolera mu dzenje laling'ono pansi pa chipolopolo cha aluminiyamu. Khomo lamkati limagwiritsa ntchito mphete yamakona anayi ndi diaphragm kuti alekanitse firiji ndi gawo lamagetsi ndikusindikiza nthawi yomweyo.

Kupsyinjika kukafika pamtengo wotsika wa 0.225 + 0.025-0.03MPa, diaphragm yotsika kwambiri (chidutswa chimodzi) imatembenuzidwa, mpando wa diaphragm ukukwera mmwamba, ndipo mpando wa diaphragm umakankhira bango lakumtunda kuti likwere mmwamba, ndipo zolumikizira za bango lakumtunda zili pansi pa mbale yachikasu. Kulumikizana kwa compressor kumalumikizidwa, ndiko kuti, kuthamanga kwapansi kumalumikizidwa, ndipo kompresa imayamba kuthamanga.

Mavuto akupitiriza kukwera. Ikafika pamtengo wotsika kwambiri wa 3.14 ± 0.2 MPa, diaphragm yothamanga kwambiri (zidutswa 3) imatembenuka, kukankhira ndodo ya ejector m'mwamba, ndipo ndodo ya ejector imakhazikika pa bango lakumunsi, kotero kuti bango lakumunsi limasunthira mmwamba, ndi kukhudzana pa mbale yotsika yachikasu Mfundoyi imasiyanitsidwa ndi kukhudzana ndi bango lapamwamba, ndiko kuti, kuthamanga kwakukulu kumachotsedwa, ndipo compressor imasiya kugwira ntchito.

Kupanikizika kumachepa pang'onopang'ono (mwachitsanzo, kuchepa). Pamene kupanikizika kumatsikira kumtengo wapamwamba wosinthira-pamtengo wotsika 0.6 ± 0.2 MPa, diaphragm yothamanga kwambiri imachira, ndodo ya ejector imatsika pansi, ndipo bango lapansi limachira. The kukhudzana pa m'munsi mbale chikasu ndi kukhudzana pamwamba bango kubwezeretsedwa. Kulumikizana ndi mfundo, ndiko kuti, kuthamanga kwakukulu kumalumikizidwa, kompresa imagwira ntchito.

Kupanikizika kukatsikira kumtengo wotsika wa 0.196 ± 0.02 MPa, diaphragm yotsika kwambiri imachira, mpando wa diaphragm umayenda pansi, bango lakumtunda limabwereranso pansi, ndipo kukhudzana kwa tsamba lachikasu kumtunda kumasiyana ndi kukhudzana. pa bango lapansi, ndiye kuti, kutsika kwapang'onopang'ono , Compressor imasiya kugwira ntchito.

Pogwiritsidwa ntchito kwenikweni, chosinthiracho chimachotsedwa pamene palibe kukakamizidwa. Imayikidwa mu makina owongolera mpweya wagalimoto. Firiji ikadzazidwa (nthawi zambiri 0.6-0.8MPa), chosinthira choponderezedwa chimakhala paboma. Ngati firiji sichikutha, Dongosolo limagwira ntchito bwino (1.2-1.8 MPa);Tamayatsa nthawi zonse.

wNkhuku kutentha kumakhala pamwamba pa madigiri asanu ndi awiri kapena asanu ndi atatu, Pamene dongosolo silikugwira ntchito bwino, monga kutentha kwabwino kwa condenser kapena zonyansa / ayezi kutsekeka kwa dongosolo, ndipo kupanikizika kwa dongosolo kumapitirira 3.14 ± 0.2 MPa, kusinthako kudzatembenuzidwa. kuzimitsa; Ngati firiji ikutha kapena kutentha kuli pansi pa madigiri asanu ndi awiri kapena asanu ndi atatu, ndipo kupanikizika kwa dongosolo kumakhala kotsika kuposa 0.196 ± 0.02 MPa, chosinthira chidzazimitsidwa. Mwachidule, kusinthaku kumateteza compressor.
