Kudzvanya Switch Kune Refrigeration System
Iyo yekudzvanya switch inonyanya kushandiswa mufiriji system, mupombi yekutenderera system yeyakanyanya kudzvanywa uye yakaderera kudzvanywa, kuchengetedza iyo isina kujairika yakanyanya kudzvanywa kweiyo system kudzivirira kukanganisa kune compressor.
Mushure mekuzadzwa, firiji inoyerera ichipinda mugoko realuminium (kureva, mukati mekuchinja) kuburikidza neburi diki riri pasi pegoko realuminium. Iyo yemukati mhango inoshandisa denderedzwa rectangular uye diaphragm kuparadzanisa refrigerant kubva kune chikamu chemagetsi uye kuchisimbisa panguva imwe chete.
Kana dzvinyiriro ichisvika kune yakaderera-pressure switch-on value 0.225 + 0.025-0.03MPa, iyo yakaderera-pressure diaphragm (1 chidimbu) inotenderedzwa, chigaro che diaphragm chinokwira kumusoro, uye chigaro che diaphragm chinosundira rutsanga rwepamusoro kuti uende kumusoro, uye zvinobatanidzira rutsanga rwepamusoro zviri pasi peplate yeyero. Kubatana kwecompressor kunobatwa, ndiko kuti, kuderera kwakabatana kwakabatana, uye compressor inotanga kumhanya.
Dzvinyiriro inoramba ichikwira. Kana yasvika pakakwirira-kudzvanya disconnect kukosha kwe3.14 ± 0.2 MPa, iyo yakakwira-pressure diaphragm (3 zvidimbu) inobhururuka, ichisundira ejector tsvimbo kumusoro, uye tsvimbo yejector inozorora parutsanga rwezasi, kuitira kuti tsanga yezasi iende kumusoro. uye kuonana pane yakaderera yellow plate Iyo poindi inoparadzaniswa kubva pakusangana parutsanga rwepamusoro, ndiko kuti, kudzvanywa kwepamusoro kunobviswa, uye compressor inomira kushanda.
Dzvinyiriro yacho inodzikama zvishoma nezvishoma (kureva inodzikira). Kana dzvinyiriro ichidonha kusvika ku-high-pressure switch-on value minus 0.6±0.2 MPa, diaphragm yepamusoro-pressure inopora, tsvimbo yejector inofamba ichidzika, uye tsanga yezasi inopora. Mabatirwo aripazasi yeyero ndiro uye macontacts ari pamusoro rutsanga anodzoreredzwa. Point yekubata, ndiko kuti, high pressure yakabatana, iyo compressor inoshanda.
Kana dzvinyiriro ichidzika kusvika kune yakaderera-pressure cut-off value ye 0.196±0.02 MPa, iyo yakaderera-pressure diaphragm inopora, chigaro che diaphragm chinofamba chichidzika, rutsanga rwepamusoro rwunodzokera pasi, uye kubatwa kwepamusoro shizha reyero kunopatsanurwa kubva pakubata. parutsanga rwezasi, kureva, low-pressure disconnect , Iyo compressor inomira kushanda.
Mukushandiswa chaiko, switch inobviswa kana pasina kudzvanywa. Yakaiswa mumotokari air conditioner system. Mushure mekunge firiji yazadzwa (kazhinji 0.6-0.8MPa), iyo yekumanikidza switch iri muhurumende. Kana iyo firiji ikasadonha, Iyo sisitimu inoshanda zvakajairika (1.2-1.8 MPa);Tanogara akabatidza.
when tembiricha iri pamusoro peanomwe kana masere madhigirii, Kana sisitimu isingashande zvakajairwa, sekutadza kupisa kwekupisa kweiyo condenser kana tsvina / ice kuvharika kweiyo system, uye iyo system yekumanikidza inodarika 3.14 ± 0.2 MPa, switch inoshandurwa. Kudzima; Kana firiji ichidonha kana tembiricha iri pazasi manomwe kana masere madhigirii, uye system pressure yakadzikira pane 0.196±0.02 MPa, switch inodzimwa. Muchidimbu, switch inodzivirira compressor.
