Chii chinonzi sensor yemhepo inotonhodza yemotokari
Chinogadzirisa mhepo inotonhodza mota ndicho chinhu chikuru chegadziriro yekutonhodza. Basa rayo guru nderekutarisa kumanikidzwa kwemhepo inotonhodza mupayipi yemhepo inotonhodza panguva chaiyo, kuona kuti compressor inoshanda zvakachengeteka, uye kushanda nezvimwe zvinhu kudzora kutanga nekumira kwefeni inotonhodza necompressor. Kazhinji inoiswa mupombi ine mhepo inotonhodza ine pressure yepamusoro muchikamu cheinjini uye inotumira data rekumanikidzwa rakaunganidzwa kuECU yeinjini kana imwe unit yekudzora mhepo inotonhodza. Kana ECU ikagamuchira chiratidzo chekumanikidzwa kwakajairika, inotanga compressor nefeni inotonhodza; Kana chiratidzo chekumanikidzwa chisina kujairika chikaonekwa, matanho ekukurumidzira anotorwa kudzivirira michina yekutonhodza yakaita secompressors kuti isatange, nokudaro ichidzivirira sisitimu yese yekutonhodza.
Chinopa mhepo inotonhodza chinowanzo gadzira dhizaini yesystem ine waya nhatu, nzira yayo yekudzora inosanganisira chiratidzo cheanalog, Lin bus uye duty cycle control mhando nhatu. Kuti uedze chinopa mhepo inotonhodza, shandisa multimeter kuyera tambo yemagetsi, tambo yepasi, uye tambo yechiratidzo yesensor. Muzviitiko zvakajairika, tambo yemagetsi i5V kana 12V, tambo yepasi i0V, uye tambo yechiratidzo inochinja-chinja kubva pa0.5V kusvika 4.5V kana 1V kusvika 5V. Kana kukosha kwakayerwa kwakasiyana zvakanyanya nekwakajairika, zvinogona kureva kuti sensor yakakuvara kana kuti pane kubatana kwechokwadi muharness.
Chinodziisa mhepo ine simba rekuisa mhepo ine simba chinoita basa guru mufiriji yemota. Kana chinodziisa mhepo isina simba, zvinogona kukonzera kusatonhodza mumota, compressor haigone kushanda, kana matambudziko ekumisa nekuvhura nguva nenguva. Saka, kuongorora nguva dzose nekugadzirisa chinodziisa mhepo ine simba rekuisa mhepo ine simba chinhu chakakosha kuti ive nechokwadi chekuti chinodziisa mhepo ine simba rekuisa ...
Nheyo yekushanda kwesensor yemhepo inotonhodza mweya inobva pakuyera kumanikidzwa, kazhinji kacho ine firimu rakatetepa uye grid ye resistors. Kana kumanikidzwa kuri mu automotive air conditioning system kuchichinja, kumanikidzwa kwemedium yakayerwa kunoendeswa kufirimu iri mu sensor. Firimu rinoshanduka pasi pesimba rekumanikidzwa, zvichikonzera shanduko ye resistance grid pafirimu. Kuchinja uku kwe resistance kunogona kuonekwa uye kuverengwa ne circuit yakabatana ne dashboard kana imwe control unit.
Kushandiswa kwemasensa ekumanikidza mweya wemotokari mumagetsi emhepo kunosanganisira mhando dzakawanda, mhando yega yega ine basa rayo uye nzvimbo yekuisirwa. Semuenzaniso, switch ine voltage yakakwira inoiswa papombi yekupinda ye condenser kuti igadzirise kumhanya kwemota yefeni uye ive nechokwadi chekuti kumanikidzwa kwe condenser kuri mukati menzvimbo yakachengeteka. Kana kumanikidzwa kwe condenser kwakaderera pane 1.51 mpa, feni inoramba ichishanda nekukurumidza. Kana kumanikidzwa kwapfuura 1.5 mpa, feni inokurumidza kusvika pakumhanya kukuru. Pamusoro pezvo, switch ine tembiricha mbiri inowanikwa padivi pe condenser uye inosanganisa switch ine pressure yakakwira netembiricha yeinjini inotonhorera kuti itonge mashandiro emota yefeni inotonhorera. Kana tembiricha ye coolant iri pakati pe95 ne102 ° C, feni inotenderera nekumhanya kwakaderera; Kana tembiricha yapfuura 102 ° C, feni inoshanda nekumhanya kukuru.
Basa remuchina wemhepo inotonhodza mweya mumotokari nderekuchengetedza sisitimu yemhepo inotonhodza mweya uye kuvandudza mashandiro. Anodzivirira kumanikidzwa kwakanyanya kuti kusakonzere kukuvara kwezvikamu nekutarisa shanduko dzekumanikidzwa mukati mesisitimu. Semuenzaniso, kana kumanikidzwa kwemutsara wepamusoro kuri pasi pe0.2 mpa kana kupfuura 3.2 mpa, clutch yemagetsi yecompressor inobviswa kuti idzivirire sisitimu; Clutch inoramba ichishanda pakati pe0.22 ne3.2 mpa. Pamusoro pezvo, switch yekunze inobvisa clutch yecompressor electromagnetic kana tembiricha iri pasi pe5 ° C, zvichidzivirira compressor yemhepo kuti isashande patembiricha yakaderera.
Kana uchida kuziva zvakawanda, ramba uchiverenga zvimwe zvinyorwa pane ino saiti!
Ndapota tifonerei kana muchida zvigadzirwa zvakadaro.
