Basa re sensor yekumanikidza mafuta emotokari
Basa guru re automobile oil pressure sensor nderekuona kumanikidzwa kwemafuta uye kuridza alarm kana kumanikidzwa kusina kukwana . Oil pressure sensor inoiswa papombi huru yemafuta yeinjini, inoona kumanikidzwa kwemafuta kuburikidza nemudziyo wekuyera kumanikidzwa, uye inoshandura ma pressure signals kuita ma electric signals, ayo anotumirwa ku signal processing circuit. Kana oil pressure yaderera pasi pe preset safe value, oil indicator light iri padashboard inobatidza kuti mutyairi azive .
Musimboti wekushanda
Pane kusliding resistance mukati me oil pressure sensor, uye kuchinja kwe oil pressure kuchasunda sliding resistance potentiometer kuti ifambe, uye yobva yachinja current ye oil pressure gauge, kuitira kuti pointer position ichinje. Panguva imwe chete, chiratidzo chinotumirwa ku oil pressure indicator kuburikidza nesignal line, uye ratio ye current inopfuudzwa ne two coils mu indicator inochinjwa, zvichiratidza starting motor . Iyo sensor inowanzo kuve ne thick film pressure sensor chip, signal processing circuit, housing, fixed circuit board device uye two leads. Iyo signal processing circuit inosanganisira power supply circuit, sensor compensation circuit, zeroing circuit, voltage amplification circuit, current amplification circuit, filter circuit uye alarm circuit .
Nzvimbo yekuiswa
Sensor yekumanikidza mafuta inowanzoiswa papombi huru yemafuta yeinjini, uye dzimwe nguva pachigaro chefirita yemafuta. Sensor iyi inoumbwa necontact, spring, diaphragm uye diaphragm. Kana pasina oil pressure, spring inosunda diaphragm kuti ivhare contact; Kana pressure yasvika pamutengo wakatarwa, diaphragm inokunda simba re spring uye inotyora contact .
Zviratidzo zvekutadza kushanda kwe sensor yemafuta emotokari zvinosanganisira zvinhu zvinotevera:
Kana sensor yekumanikidza mafuta ikakuvara, chiratidzo chekumanikidza mafuta chinoramba chichipenya, zvisinei nekumanikidzwa kwemafuta chaiko, izvo zvinogona kutsausa mutyairi kuti atende kuti kumanikidzwa kwemafuta einjini hakuna kujairika.
Kugara kwakasimba: Mwenje pamwenje wekutadza kweinjini (unozivikanwawo seMIL kana kuti mwenje wekutarisa injini) unowanzoreva kuti pane dambudziko raonekwa nehurongwa hwekudzora mafambiro emagetsi emotokari. Kukundikana kwesensa yemafuta ndicho chimwe chezvikonzero zvinoita kuti mwenje ubate.
Kuratidzwa kwekumanikidzwa kwemafuta kusina kujairika: Kana mota isingashande zvakanaka, kana sensor yekumanikidzwa kwemafuta ikakundikana, kukosha kwekumanikidzwa kwemafuta kunoratidzwa padashboard kunogona kunge kusina kujairika, sekunge kunoratidzwa nguva dzose semutengo wakatarwa (senge 0.99) kana huwandu hwekusajairika kwekushanduka.
Kodhi yekukanganisa P01CA inoonekwa : Kana sisitimu yekuongorora mota ikaona kuti voltage ye sensor yekumanikidza mafuta iri kunze kwehuwandu hwakajairika, kodhi yekukanganisa inoenderana nayo, senge P01CA, icharekodhwa uye icharatidzwa. Iyi kodhi yekukanganisa inoratidza zvakananga dambudziko ne sensor yekumanikidza mafuta.
Zvikonzero zvekukundikana kwe sensor yekumanikidza kwemafuta zvinogona kusanganisira:
Sensor pachayo haina kunaka: zvikanganiso zvekugadzira kana kukwegura zvinoita kuti pave nekuonekwa kusina kururama kana kukuvara.
Matambudziko emutsetse: Short circuit, open circuit kana kusabatana zvakanaka zvinogona kukanganisa kutapurirana kwemasaini.
Kumanikidzwa kwemafuta kusina kujairika: kumanikidzwa kwemafuta kwakakwira kana kwakaderera kunounza kumanikidzwa kukuru kune sensor.
Kusvibiswa kwetsvina: Tsvina inobva mukati meinjini inogona kuvhara kana kusvibisa masensa.
Nzvimbo yekuisa isiriyo : kutsauka kwenzvimbo yekuisa kuchakanganisa kunyatsoonekwa kwesensa.
zvimwe zvikamu zvekutadza kushanda zvakanaka kweinjini: zvakaita sekuvharika kwefirita, kusakwana kwemafuta, nezvimwewo.
Kusagadzikana kwemagetsi emagetsi: kushanduka kwemagetsi kunokanganisa mashandiro akajairika e sensor.
Kupfupika kwemhepo mukati kunokonzerwa ne sensor inopinda mumvura kana mumafuta.
Nzira dzekuongorora nekurapa:
Shandisa chishandiso chekuongorora : verenga kodhi yekukanganisa nekubatanidza OBDII diagnostic interface, semuenzaniso P0520 (oil pressure sensor circuit fault).
Tarisa kubatana kwetambo nesensa: iva nechokwadi chekuti kubatana kwetambo hakuna ngura, kuputsika, kana kusuduruka.
Kuyera voltage inobuda yesensor: Shandisa multimeter kuyera voltage inobuda yesensor uye kuve nechokwadi chekuti inoburitsa voltage yakakodzera pasi pekumanikidzwa kwakasiyana.
Kuenzanisa kwekuyerwa kwesimba remagetsi: Bvisa sensor yemagetsi yemafuta emagetsi woisa iyo mechanical pressure gauge yekuyedzwa kwekuenzanisa kuti uone kana sensor isiri kushanda.
Tsiva sensor : Kana sensor ikasimbiswa kuti haishande, itsive ne sensor itsva inoenderana nemota yekutanga.
Kana uchida kuziva zvakawanda, ramba uchiverenga zvimwe zvinyorwa pane ino saiti!
Ndapota tifonerei kana muchida zvigadzirwa zvakadaro.
Zhuo Meng Shanghai Auto Co., Ltd. yakazvipira kutengesa zvikamu zvemotokari zveMG&750 zvinogamuchirwa Kutenga.
