Iinjini zemveli nazo zineesekethe zamanzi okupholisa, kodwa iisekethe zamanzi zokupholisa zezithuthi zamandla amatsha zihluke kakhulu.Esi sahluko sijonga indlela amanzi okupholisa adibana ngayo kunye nee-actuator ezahlukeneyo kunye neenzwa kwizithuthi zamandla amatsha.
Impompo yamanzi ye-elektroniki
Ukwenza ukuba isisipholisi sihambe kwisekethi yokupholisa nganye, ngokuqinisekileyo impompo iyafuneka.I-injini iqhuba impompo yamanzi yoomatshini ngenxa yokujikeleza kweshafu ye-injini.Kwizithuthi zombane ezicocekileyo kunye nezithuthi ezixubileyo, ngenxa yokudityaniswa kweemfuno zokupholisa kunye nesantya se-motor shaft, iimpompo zamanzi zombane zisetyenziselwa ukuhlangabezana neemfuno ezichanekileyo zokulawula ubushushu.
Inxalenye yehydraulic yempompo yamanzi ye-elektroniki ayahlukanga kakhulu kumpompo wamanzi womatshini.Umahluko ophambili ulele kwinxalenye yomqhubi wombane wempompo yamanzi ye-elektroniki.Ukujikeleza kwempompo yamanzi ye-elektroniki ibonelelwa yi-brushless DC motor.Amandla eenjini ukusuka kwi-30W ukuya kwi-150W, enokuthi igubungele ngokusisiseko uninzi lweemodeli ezicocekileyo zombane kunye ne-hybrid kunye nezakhiwo zolawulo lwe-thermal, ngaphandle kokuba i-fuel cell stack iya kusebenzisa impompo yamanzi ye-200W nangaphezulu..Kukho ezinye iimpompo zamanzi ezisebenzisa ii-motor brushed, kodwa kuyacetyiswa ukuba kusetyenziswe ii-motor brushless, ezinobomi obude kunye nengxolo encinci.
Ukongeza kwi-DC brushless motor pump drive, ezinye iisekethe zingongezwa kwibhodi yesekethe eprintiweyo yePCB.Impompo yamanzi ye-elektroniki ye-EVngokweemfuno zokusebenza.Impompo yamanzi ye-elektroniki ingasebenzisa ulawulo lwe-PWM okanye ulawulo lwebhasi ye-LIN (kukwakho nolawulo lwebhasi ye-CAN).
Iipompo zamanzi ze-elektroniki ezilawulwa yi-LIN zinconywa kwizithuthi zombane ezicocekileyo, kuba kukho ngokubanzi iimpompo zamanzi kunye neevalvu zamanzi ezisetyenziswa kwi-architecture yolawulo lwe-thermal yezithuthi zombane ezicocekileyo.Ukuba impompo nganye yamanzi kunye nevalve yamanzi isebenzisa ulawulo lwe-PWM, umlawuli wolawulo lwe-thermal kufuneka anike i-IO ehlukeneyo yeepompo kunye neevalve.Ibhasi ye-LIN yanele ukukhwela zonke iimpompo zamanzi kunye neevalve zamanzi ezisetyenziselwa izithuthi zombane ezicocekileyo (i-LIN inokudibaniswa kwii-nodes ze-16).
Ngokokubekwa komzekelo, ukrelekreleIiPumpu zokupholisa iSithuthi zeDckunye neevalvu zamanzi zombane nazo zinokuqwalaselwa.Umzekelo, kwimifuziselo ephakathi ukuya phezulu, ukusetyenziswa kwezixhobo zokulawula ubushushu obukrelekrele kunokuphucula le misebenzi: i-voltage overvoltage/undervoltage isilumkiso, isilumkiso sePCB overheating, ukubekwa esweni kwempompo yamanzi, isilumkiso sokugcwala kwempompo yamanzi, ukubonwa kwempompo yamanzi. , njl. Idityaniswe nomsebenzi we-Intanethi yeZithuthi, inokuphinda ibeke iliso kumacandelo enkqubo yolawulo lwe-thermal kwifu ngexesha langempela ukufezekisa imisebenzi ethile ephezulu ephezulu efana nokuxilongwa kwempazamo, ukubikezela ukungaphumeleli, kunye nohlalutyo lobomi.
