Kunyaka ophelileyo, ibhasi yombane ecocekileyo ifumene ukungasebenzi ngequbuliso kwe-brake assist kwindawo eqhubekayo yokwehla kweYunnan-Guizhou Plateau. Uphando lufumanise ukuba unobangela yayikukungasebenzi kakuhle kwe-vacuum controller okubangele ukuba i-vacuum pump ime, kwaye itanki ye-vacuum encinci yayingenawo amandla okugcina, nto leyo ephantse yabangela ingozi enkulu1. Eli tyala latyhila iingozi zoyilo lweenkqubo zemveli ze-vacuum assist kwaye lenze ukuba ishishini liqalise ukujonga kwakhona indima ephambili yee-micro DC vacuum pumps kwiinkqubo ze-elektroniki zezithuthi.

Kutheni izithuthi zombane kufuneka zixhomekeke kwiimpompo ezincinci ze-vacuum?

Kwizithuthi zepetroli zemveli, i-injini intake manifold ngokwendalo ivelisa uxinzelelo olubi, inika umthombo we-vacuum wasimahla kwinkqubo yokuncedisa iibhuleki4. Nangona kunjalo, izithuthi zombane azinawo injini, kwaye ngaphandle komthombo we-vacuum, i-brake pedal iba nzima kakhulu - amandla okubhuleka okubhuleka ngesandla kuphela akahlangabezani neemfuno zokhuseleko.

Ngeli xesha,ipompo ye-vacuum ye-micro DCu-p uba sisisombululo sodwa:

Ukuqhuba ngombane: sebenzisa ngokuthe ngqo umbane wesithuthi se-12V/24V, qhuba i-piston okanye i-diaphragm ukuze ihambe ngesantya esiphezulu kwi-motor, kwaye ukhuphe i-vacuum3 ngokukhutheleyo;

Impendulo ekhawulezileyo:Umzekelo, i-HD-PC3025N inokumisela uxinzelelo olubi lwe--70kPa ngaphakathi kwesekhondi eli-1 ukuhlangabezana neemfuno zokuqhobosheka ezingxamisekileyo3;

Ubonelelo lwamandla oluzimeleyo:ayithintelwanga ziimeko zokusebenza kwenjini, ingasebenza nokuba imoto ayimi ndawonye

Iimpompo ze-vacuum ezincinci ziyoyisa njani imiqobo kwaye zihlangabezane neemfuno ezingqongqo zeemoto?

1. Izalathisi zokusebenza: ibhalansi phakathi kwe-vacuum kunye nokuhamba kwamanzi

Umngeni wePlateau:Kwindawo ephakamileyo yeemitha ezingama-3,000, uxinzelelo lomoya luyehla luye kwi-70kPa (101kPa kwindawo ethe tyaba). Ukuba i-vacuum eqhelekileyo yepompo yi--50kPa kuphela, uxinzelelo olusebenzayo olungalunganga luya kubola luye kwi--20kPa, nto leyo ebangela ukungabikho okukhulu kwe-brake assist. Ke ngoko, kuyimfuneko ukukhetha imodeli ene-vacuum ye-≥-70kPa (njenge-PC3025N) ukuze ushiye umda wokhuseleko.

Ukuncitshiswa kokuhamba kwamanzi:Kwimpompo enomsinga oqhelekileyo we-25L/min, umsinga wokwenyani unokwehla uye kwi-15L/min emva kokudibanisa umbhobho wemitha e-1 + iingqiniba ezi-2. Ngexesha lokuqhobosha okuqhubekayo (njengokwehla okude), ukuba umsinga awonelanga kwaye uxinzelelo lwetanki ye-vacuum alunakugcinwa, i-alamu yebhuleki iya kuqaliswa.

 

2.Ukuthembeka: Umshuwalense ophindwe kabini wokuqina kunye nokuthintela ukungaphumeleli

Uvavanyo lokunyamezela lweeyure ezili-1500:I-Ruhaizhibo iEVP Pro yenziwe ngcono ngee-rotors ze-graphite, kwaye ubomi bayo budlula obo bakhuphisana nabo bamazwe ngamazwe.

Inyathelo lesi-2: Hlanganisa i-vacuum kunye ne-flow

Jonga itafile ngokukhawuleza (ukuthatha iimodeli eziqhelekileyo zePincheng njengomzekelo)

 

Uyilo olungafunekiyo lwesilawuli esiphindwe kabini:Inkqubo entsha isebenzisa izilawuli ezimbini ze-vacuum ezihambelanayo. Ukuba enye iyasilela, enye isenokulawula ipompo ukuba isebenze, isuse ukusilela kwenqaku elinye

Icebo lokunciphisa umthwalo elikrelekrele:Xa kufunyaniswa ukuvuza kwe-vacuum (i-gradient yoxinzelelo olungaqhelekanga), itshintshela ngokuzenzekelayo kwimo yokusebenza engapheliyo ukuthintela imoto ukuba ingatshi.

Ukulungelelana nokusingqongileyo: ukusuka ekubeninda kakhulu ukuya kumswakama ophezulu

Ukunyamezela umphunga wamanzi:Inkqubo yeebhuleki inokungenisa umoya ofumileyo, kwaye iimpompo eziqhelekileyo zinomngcipheko wokugqwala. Nangona kunjalo, i-PC mini vacuum pump ivumela ukuba le medium "ityebile ngomphunga wamanzi" kwaye isebenzisa izitywino ze-fluororubber ngaphakathi.

-30℃ ukuqala okubandayo:iimpompo zeemoto ezingenamabhrashi (ezifana nothotho lwe-VML) zisenokusabela ngokukhawuleza kumaqondo obushushu aphantsi, ziphepha umngcipheko wokuqina kweenkqubo ze-hydraulic zemveli

 

3. Imingeni yokwenyani: Iingxaki kunye nezisombululo zeMicroi-vacuumiimpompo

Nangona le teknoloji sele ivuthiwe, ii-micro pumps zisajongene neengxaki ezintathu eziphambili xa zisetyenziswa:

Ukusetyenziswa kwamandla kunye nengxabano ye-NVH (ingxolo kunye nokungcangcazela)

Iimpompo ezihamba ngamandla aphezulu zihlala zinamandla angaphezu kwama-40W, kwaye ukusebenza rhoqo kudla amandla amakhulu (amalunga ne-0.5% yoluhlu lwesithuthi sombane). Kwangaxeshanye, ingxolo yemoto ingadluliselwa kwi-cockpit. Izisombululo:

Injini engenabhrashi + ulawulo lwefrikhwensi eguquguqukayo: Umzekelo, uthotho lwe-VML lunciphisa ukusetyenziswa kwamandla okungasebenzi ngokulawula isantya7;

Isigqubuthelo esithintela isandi + ukunciphisa ukungcangcazela kwepayipi: isisombululo esiqhelekileyo kwii-OEM.

Umngcipheko wobushushu obugqithisileyo kwiindawo ezixineneyo kunye neemeko zokuvuza

Kwiindawo ezithe tyaba okanye xa isitywino singasebenzi, ipompo inokutshisa kakhulu ngenxa yokusebenza ixesha elide. Isilawuli esitsha ngobuchule siyayimisa ipompo ngokujonga i-pressure gradient:

Ukuba i-pressure drop gradient ingaphantsi kwe-8mbar/s kwimizuzwana eli-10 yokusebenza, inkqubo igwetywa njengeqhelekileyo kwaye ipompo iyekiswa ngoko nangoko;

Ukuba i-gradient ayiqhelekanga (ukuvuza), iya kungena kumjikelo wokukhusela "imizuzwana eli-15 yokusebenza + imizuzwana eli-10 yokuma"4.

Umdlalo wendawo kunye neendleko

Iimpompo ezinkulu ezihambayo (ezifana nePC3025N) zinobunzima obuyi-1kg kwaye zithatha indawo ye-chassis. Nangona isisombululo se-dual controller + i-vacuum tank enkulu siphucula ukuthembeka, iindleko zinyuka malunga ne-30%15. Indlela yoshishino kuyilo oludibeneyo: I-Haizhibo ifaka i-controller emzimbeni wepompo ukunciphisa iintambo zocingo kunye nee-interfaces6.

 

Isikhokelo sexesha elizayo: asiyonto nje "yokuxhasa"

Ngokuphuculwa kokuqhuba ngobuchule, imisebenzi yeempompo ezincinci zokucoca umoya iyanda:

Inkxaso engafunekiyo yokuqhuba ngokuzimeleyo ngaphezulu kwenqanaba le-L3:Xa ibhuleki ye-hydraulic ye-elektroniki ingaphumeleli, inkqubo ye-vacuum booster ithatha indawo njenge-mechanical backup7;

Umoya oxutyiweyo osebenzayo:Ezinye iimodeli zisebenzisa ipompo efanayo ye-vacuum ukunika amandla isipringi somoya, zisenza "ipompo enye yokusetyenziswa okuninzi"6;

Ukujikeleza kwe-hydrogen kwisithuthi se-hydrogen fuel cell:Iimpompo ezincinci ezingamelani nokugqwala zisetyenziswa kwinkqubo yokujikeleza kwe-hydrogen ukuphucula ukusetyenziswa kwamafutha3.

 

Isiphelo: Izinto eziphambili, kodwa kufuneka ukulungiswa kwinqanaba lenkqubo

Iimpompo ze-vacuum ze-Micro DC ziyahlangabezana ngokupheleleyo neemfuno zoncedo lombane zezithuthi zombane zanamhlanje, kodwa kufuneka "zikhethwe ngokweempawu":

Iimoto zosapho:Inqanaba le-PC3025N (-70kPa, 25L/min) elinesilawuli esinye + itanki yokufunxa ye-8L yanele8;

Iimoto zorhwebo/iimodeli zasezintabeni: zifuna iimpompo ezingaphezulu kwe--80kPa + izilawuli ezimbini + iitanki ezinkulu ze-vacuum eziyi-15L, kwaye zilungiselele ukujonga i-pressure gradient14;

Iimoto ezikrelekrele zexesha elizayo:Iimpompo zeemoto ezingenabhrashi (ezifana neVML) ziya kuba zizinto eziqhelekileyo, kuthathelwa ingqalelo ukusebenza kakuhle, ukuzola kunye nolawulo olukrelekrele67.

Njengoko iinjineli zivumelana: Nokuba inamandla kangakanani na ipompo enye, ayilunganga njengolungelelwaniso lwenkqubo "yepompo-itanki-yokulawula-inzwa". Xa ukhetha, akufuneki ujonge kuphela iiparameter eziqhelekileyo zepompo, kodwa kwakhona uqinisekise umthamo wayo womthwalo kunye nendlela yokuphendula iimpazamo kwinkqubo yonke yesithuthi - emva kwayo yonke loo nto, ii-milliseconds phakathi kweebhuleki zimisela umda wokhuseleko lobomi.

Shenzhen Pincheng Motorunamava eminyaka emininzi kwi-R&D nakwimveliso yeiimpompo ezincinci ze-vacuum, kwaye uphumelele isiqinisekiso seemoto i-IATF 16949, esinokubonelela ngezisombululo ezilungileyo zokuvelisa iindawo zeemoto.
