Iinjini zemveli nazo zineesekethe zamanzi okupholisa, kodwa iisekethe zamanzi okupholisa zezithuthi zamandla amatsha zahlukile kakhulu. Esi sahluko sijonga indlela amanzi okupholisa asebenzisana ngayo nee-actuators ezahlukeneyo kunye nee-sensors kwizithuthi zamandla amatsha.
Impompo yamanzi ye-elektroniki
Ukuze i-coolant ihambe kwisekethe nganye yokupholisa, ewe, kufuneka ipompo. Injini iqhuba ipompo yamanzi yoomatshini ngenxa yokujikeleza kweshafti yenjini. Kwizithuthi zombane ezicocekileyo kunye nezithuthi ezixutyiweyo, ngenxa yokudibanisa iimfuno zokupholisa kunye nesantya seshafti yemoto, iipompo zamanzi ze-elektroniki zisetyenziselwa ukuhlangabezana neemfuno zolawulo lobushushu ezichanekileyo.
Inxalenye ye-hydraulic yepompo yamanzi ye-elektroniki ayihlukanga kangako kwipompo yamanzi yoomatshini. Umahluko ophambili ukwinxalenye ye-electric drive yepompo yamanzi ye-elektroniki. Ukujikeleza kwepompo yamanzi ye-elektroniki kunikezelwa yimoto ye-DC engenamabhrashi. Amandla emoto aqala kwi-30W ukuya kwi-150W, enokubandakanya uninzi lweemodeli zombane ezicocekileyo kunye ne-hybrid kunye noyilo lolawulo lobushushu, ngaphandle kokuba i-fuel cell stack iya kusebenzisa ipompo yamanzi engama-200W nangaphezulu. . Kukwakho neepompo zamanzi ezisebenzisa iimoto ezibrashiweyo, kodwa kuyacetyiswa ukusebenzisa iimoto ezingenamabhrashi, ezinobomi obude kwaye zingangxoli kangako.
Ukongeza kwi-DC brushless motor pump drive, ezinye iisekethe zingongezwa kwibhodi yesekethe eprintiweyo ye-PCB yeImpompo yamanzi ye-elektroniki ye-EVngokweemfuno zokusebenza. Ipompo yamanzi ye-elektroniki ingasebenzisa ulawulo lwe-PWM okanye ulawulo lwebhasi ye-LIN (kukwakho nolawulo lwebhasi ye-CAN).
Iimpompo zamanzi ze-elektroniki ezilawulwa yi-LIN ziyacetyiswa kwizithuthi zombane ezicocekileyo, kuba ngokubanzi kukho iimpompo zamanzi ezininzi kunye neevalvu zamanzi ezisetyenziswa kuyilo lolawulo lobushushu kwizithuthi zombane ezicocekileyo. Ukuba ipompo nganye yamanzi kunye nevalvu yamanzi isebenzisa ulawulo lwe-PWM, umlawuli wolawulo lobushushu kufuneka anike i-IO eyahlukileyo kwiimpompo kunye neevalvu. Ibhasi ye-LIN yanele ukufaka zonke iimpompo zamanzi kunye neevalvu zamanzi ezisetyenziswa kwizithuthi zombane ezicocekileyo (i-LIN inokuqhagamshelwa kwiindawo ezili-16).
Ngokwendlela imodeli ebekwe ngayo, ikrelekreleIimpompo zeDc zokuPholisa iiMotokunye neevalvu zamanzi ze-elektroniki nazo zinokuqwalaselwa. Umzekelo, kwiimodeli eziphakathi ukuya kweziphezulu, ukusetyenziswa kwee-actuators zolawulo lobushushu ezikrelekrele kunokunceda le misebenzi: isilumkiso se-voltage overvoltage/undervoltage, isilumkiso se-PCB overheating, ukujonga i-Water pump stall, isilumkiso se-water pump overload, ukufunyanwa kwe-water pump idling, njl. Idibene nomsebenzi we-Intanethi yeZithuthi, inokujonga kwakhona izinto zenkqubo yolawulo lobushushu efini ngexesha langempela ukufezekisa imisebenzi ethile ephezulu efana nokuxilongwa kweempazamo, ukuqikelela ukungaphumeleli, kunye nohlalutyo lobomi.
