Izinjini zendabuko nazo zinezijikelezo zamanzi okupholisa, kodwa izijikelezo zamanzi okupholisa zezimoto ezintsha zamandla empeleni zihlukile kakhulu. Lesi sahluko sibheka indlela amanzi okupholisa asebenzisana ngayo nama-actuator ahlukahlukene kanye nezinzwa ezimotweni ezintsha zamandla.
Iphampu yamanzi kagesi
Ukuze i-coolant igeleze kumjikelezo ngamunye wokupholisa, vele ipompo iyadingeka. Injini ishayela ipompo yamanzi emishini ngenxa yokujikeleza kweshafti yenjini. Ezimotweni zikagesi ezihlanzekile kanye nasezimotweni ezixubile, ngenxa yokuhlanganiswa kwezidingo zokupholisa kanye nesivinini seshafti yemoto, amaphampu amanzi kagesi asetshenziswa ukuhlangabezana nezidingo zokulawula izinga lokushisa ezinembile.
Ingxenye ye-hydraulic yephampu yamanzi kagesi ayihlukile kakhulu ephampini yamanzi kagesi. Umehluko omkhulu usengxenyeni yokushayela kagesi yephampu yamanzi kagesi. Ukujikeleza kwephampu yamanzi kagesi kunikezwa yimoto ye-DC engenamabhulashi. Amandla emoto asukela ku-30W kuya ku-150W, okungamboza iningi lamamodeli kagesi ahlanzekile kanye ne-hybrid kanye nokwakhiwa kokuphathwa kokushisa, ngaphandle kokuthi i-fuel cell stack izosebenzisa iphampu yamanzi engu-200W nangaphezulu. . Kukhona futhi amaphampu amanzi asebenzisa ama-motor axutshwe, kodwa kunconywa ukusebenzisa ama-motor angenamabhulashi, aphila isikhathi eside futhi anomsindo omncane.
Ngaphezu kwe-DC brushless motor pump drive, ezinye izifunda zingangezwa ebhodini lesifunda eliphrintiwe le-PCB le-Iphampu yamanzi kagesi ye-EVngokwezidingo zokusebenza. Iphampu yamanzi kagesi ingasebenzisa ukulawula kwe-PWM noma ukulawula kwebhasi le-LIN (kukhona nokulawula kwebhasi le-CAN).
Amaphampu amanzi kagesi alawulwa yi-LIN anconywa ezimotweni zikagesi ezihlanzekile, ngoba ngokuvamile kuneziphampu zamanzi eziningi namavalvu amanzi asetshenziswa ekwakhiweni kokuphathwa kokushisa kwezimoto zikagesi ezihlanzekile. Uma iphampu yamanzi ngayinye nevalvu yamanzi isebenzisa ukulawula kwe-PWM, isilawuli sokuphathwa kokushisa sidinga ukunikeza i-IO ehlukile yamaphampu namavalvu. Ibhasi le-LIN lanele ukufaka wonke amaphampu amanzi namavalvu amanzi asetshenziswa ezimotweni zikagesi ezihlanzekile (i-LIN ingaxhunywa kuma-node angu-16).
Ngokusho kwendawo imodeli ebekwe kuyo, ihlakaniphileAmaphampu e-Dc Okupholisa Imotokanye nama-valve amanzi kagesi nakho kungacatshangelwa. Isibonelo, kumamodeli aphakathi kuya kwaphezulu, ukusetshenziswa kwama-actuator okuphatha ukushisa ahlakaniphile nakho kungacebisa le misebenzi: isexwayiso se-voltage overvoltage/undervoltage, isexwayiso sokushisa ngokweqile kwe-PCB, ukuqapha i-Water pump stall, isexwayiso se-water pump overload, ukutholwa kwe-idling pump pump, njll. Uma ihlanganiswe nomsebenzi we-Inthanethi Yezimoto, ingaphinde iqaphe izingxenye zohlelo lokuphatha ukushisa efwini ngesikhathi sangempela ukuze kufezwe imisebenzi ethile ephezulu efana nokuxilongwa kwamaphutha, ukubikezela ukwehluleka, kanye nokuhlaziywa kokuphila.
