Chii chinonzi mota air conditioning pressure sensor
Iyo yemotokari mhepo yekumanikidza kumanikidza sensor ndiyo yakakosha chikamu cheiyo firiji system. Basa rayo guru nderekutarisa kudzvanywa kwefiriji mupombi yekumisikidza mhepo munguva chaiyo, kuve nechokwadi chekushanda kwakachengeteka kwecompressor, uye kushanda nezvimwe zvikamu kudzora nemazvo kutanga uye kumira kweiyo inotonhorera fan uye compressor. Iyo inowanzoiswa mumhepo inosimudzira yakakwira kumanikidza pombi mukamuri yeinjini uye inoendesa iyo yakaunganidzwa yekumanikidza data kune injini ECU kana yakasarudzika air conditioning control unit. Kana iyo ECU inogamuchira yakajairika yekumanikidza chiratidzo, inotanga iyo compressor uye kutonhora fan; Kana chiratidzo chisina kujairika chekumanikidza chikaonekwa, matanho ekukurumidza anotorwa kudzivirira midziyo yekumisikidza mhepo senge compressors kubva pakutanga, nekudaro ichidzivirira iyo yese firiji system. .
Air conditioning pressure sensor inowanzo tora matatu-waya system dhizaini, maitiro ayo ekudzora anosanganisira analogi chiratidzo, Lin bhazi uye basa cycle control mhando nhatu. Kuyera kudzvanywa kwe sensor ye air conditioner, shandisa multimeter kuyera tambo yemagetsi, pasi tambo, uye chiratidzo tambo ye sensor. Muzviitiko zvakajairika, tambo yemagetsi ndeye 5V kana 12V, tambo yepasi ndeye 0V, uye tambo yechiratidzo inoshanduka muhuwandu hwe0.5V kusvika 4.5V kana 1V kusvika 5V. Kana iyo yakayerwa kukosha kwakasiyana zvakanyanya kubva kune yakajairwa kukosha, zvinogona kureva kuti sensor yakakuvadzwa kana kune chaiyo yekubatanidza mune harness.
Iyo air conditioning pressure sensor inoita basa rakakosha mumotokari refrigeration system. Kana iyo sensor ikatadza, inogona kutungamira mukusatonhodza mhedzisiro mumotokari, iyo compressor haigone kushanda, kana kazhinji kutanga nekumisa matambudziko. Naizvozvo, kugara uchiongorora uye kuchengetedzwa kweiyo air conditioning pressure sensor chiyero chakakosha kuti ive nechokwadi chekushanda kwakajairwa kweiyo mota air conditioning system.
Nheyo yekushanda yemotokari yemhepo yekumanikidza kudzvanywa sensor yakavakirwa pachiyero chekumanikidza, kazhinji chinosanganisira firimu rakatetepa uye gidhi revanopikisa. Kana kudzvinyirirwa mumotokari yemhepo yemhepo inogadzirisa system yachinja, kudzvanywa kwepakati yakayerwa kunoendeswa kune iyo firimu mune sensor. Iyo firimu inoshatisa pasi pechiito chekumanikidza, zvichikonzera kuenderana kwekupikisa shanduko yegidhi rekupokana pafirimu. Iyi shanduko yekupikisa inogona kuonekwa uye kuverengwa nedunhu rakabatana nedhibhodhi kana imwe control unit. .
Iko kushandiswa kwemotokari mhepo yekumanikidza kumanikidza sensors mumotokari mhepo yekumisikidza masisitimu inosanganisira akawanda marudzi, mhando yega yega ine basa rayo chairo uye nzvimbo yekuisa. Semuenzaniso, high voltage switch inoiswa pane condenser inlet pombi kugadzirisa kumhanya kwefan mota uye kuve nechokwadi chekuti condenser pressure inochengetwa mukati menzvimbo yakachengeteka. Kana iyo condensing pressure yakadzikira pane 1.51 mpa, fan inochengetedza yakaderera kumhanya kushanda. Kamwe kudzvanywa kwapfuura 1.5 mpa, fan inomhanyisa kusvika pakumhanya. Uye zvakare, kaviri tembiricha switch inowanikwa padyo necondenser uye inosanganisa iyo yakanyanya kudzvanywa switch nejini inotonhorera tembiricha kudzora kushanda kweiyo condensing fan mota. Kana tembiricha inotonhorera iri pakati pe95 ne102 ° C, fan inotenderera nekumhanya kwakaderera; Kana tembiricha yadarika 102 ° C, fan inoshanda nekumhanya kukuru.
Basa remotokari mhepo yekumanikidza kumanikidza sensor mumotokari yemhepo yekumisikidza system kuchengetedza sisitimu nekuvandudza kushanda kwayo. Ivo vanodzivirira kudzvanyirira kwakanyanya kubva mukukonzera kukuvadza kune zvikamu nekutarisa shanduko yedzvinyiriro mukati mehurongwa. Semuyenzaniso, kana high pressure line pressure iri pazasi 0.2 mpa kana pamusoro pe3.2 mpa, iyo compressor's electromagnetic clutch inodimburwa kudzivirira system; Iyo clutch inoramba yakabatikana pakati pe0.22 ne3.2 mpa. Uye zvakare, iyo yekunze tembiricha switch inobvisa iyo compressor electromagnetic clutch kana tembiricha iri pasi pe5 ° C, ichidzivirira iyo air conditioning compressor kubva pakushanda pakadzika tembiricha.
