Yintoni ivalvu yokulawula ukuhamba kwepompo yeoyile yemoto
Ivalvu yokulawula ukuhamba kwepompo yeoyile yemoto yinxalenye ebalulekileyo kwipompo yeoyile. Umsebenzi wayo ophambili kukulawula nokunciphisa ukuhamba kweoyile yenjini, ukuqinisekisa ukuba inkqubo yokuthambisa injini inokufumana unikezelo oluzinzileyo nolufanelekileyo lweoyile yenjini phantsi kweemeko zokusebenza ezahlukeneyo.
Ngokukodwa, le valve ilungisa ngokuzenzekelayo ukuhamba kwemveliso yepompo yeoyile ngokubona iiparameter ezifana noxinzelelo lwenkqubo okanye isantya senjini. Xa injini isebenza ngesantya esiphantsi okanye ingasebenzi, iya kunciphisa izinga lokuhamba ukuze kuthintelwe uxinzelelo olugqithisileyo. Xa isebenza ngesantya esiphezulu, izinga lokuhamba kufuneka lonyuswe ngokufanelekileyo ukuze kuhlangatyezwane neemfuno zokuthambisa. Lo msebenzi wokulawula unceda ukuthintela uxinzelelo lwenkqubo yokuthambisa ukuba luphezulu kakhulu okanye lube phantsi kakhulu, ngaloo ndlela lukhusela izixhobo zenjini ekugugeni okanye ekonakaleni.
Ukongeza, ivalvu yokulawula ukuhamba kwamanzi inokunceda ekuphuculeni ukusetyenziswa kwamandla kwepompo yeoyile, inciphise ukulahleka kwamandla okungeyomfuneko, kwaye incede ekugcineni ubushushu beoyile bukwinqanaba elifanelekileyo, ngaloo ndlela iphucula ukusebenza kakuhle kwenkqubo iyonke.
Umsebenzi ophambili wevalvu yokulawula ukuhamba kwepompo yeoyile yemoto (edla ngokubhekisa kwivalvu ethintela uxinzelelo okanye ivalvu elawula uxinzelelo ngaphakathi kwipompo yeoyile) kukunciphisa uxinzelelo oluphezulu lwenkqubo yokuthambisa, ukuthintela umonakalo kwiindawo zenkqubo yokuthambisa okanye ukuvuza kwepaseji yeoyile ngenxa yoxinzelelo olugqithisileyo.
Imisebenzi ethile ibandakanya:
Ukhuseleko loxinzelelo lwe-Youdaoplaceholder0: Xa isantya senjini sisanda okanye i-viscosity yeoyile yenjini itshintsha, uxinzelelo oluphumayo lwepompo yeoyile lunokudlula uluhlu olukhuselekileyo (olufana ne-0.6MPa). Ivalvu ethintela uxinzelelo iya kuvula ngokuzenzekelayo, kwaye inxalenye yeoyile yenjini iya kubuyela kwi-inlet yepompo yeoyile ngetshaneli yokunciphisa uxinzelelo ukugcina uxinzelelo oluphambili lwendlela yeoyile lungaphakathi koluhlu olukhuselekileyo lwe-0.18-0.35MPa.
Uzinzo lwenkqubo ye-Youdaoplaceholder0 : Phantsi kweemeko zokusebenza ezingaqhelekanga ezifana nezihluzi zeoyile ezivalekileyo, ivalvu ethintela uxinzelelo ingenza umsebenzi we-bypass usebenze, ivumele ioyile engahluzwanga ukuba ingene ngqo kwindawo yeoyile, iqinisekise ukuba izinto ezibalulekileyo (ezifana nee-crankshafts kunye nee-turbochargers) zifumana ukuthambisa okusisiseko kwaye ziphephe ukungqubana okomileyo.
I-Youdaoplaceholder0 Ulawulo oluguqukayo : Ivalvu elawula ioyile yezinye iimodeli zanamhlanje ilungisa uxinzelelo lweoyile ngexesha langempela ngeendlela ze-electromagnetic, isebenza ngokubambisana neyunithi yokulawula injini (ECU) ukuphucula ukusebenza kakuhle kokuthambisa kunye nokuxhasa ulawulo lwenkqubo efana nexesha levalvu eguquguqukayo.
Ukuba le valve ayisebenzi kakuhle, inokubangela uxinzelelo lweoyile olungaqhelekanga (nokuba luphezulu kakhulu okanye luphantsi kakhulu), nto leyo ekhokelela kwiingxaki ezifana nokuma, ukungabikho kwamandla aneleyo okanye ukuguguleka kwezixhobo. Kufuneka ukulungiswa ngexesha elifanelekileyo.
Ivalvu yokulawula ukuhamba kwepompo yeoyile yemoto (ekwaziwa ngokuba yivalvu yokulawula ioyile okanye ivalvu yesolenoid yepompo yeoyile) yinxalenye ebalulekileyo kwinkqubo yokuthambisa injini, enoxanduva lokulawula ukuhamba kokuphuma kunye noxinzelelo lwepompo yeoyile. Xa le valve ingasebenzi kakuhle, iya kubangela uthotho lwemisebenzi engaqhelekanga yenjini. Ezi zilandelayo ziimpawu eziqhelekileyo zeziphene:
Ubunzima bokuqalisa injini okanye ukuma ngequbuliso ngelixa uqhuba : Ukungasebenzi kakuhle kwevalvu yokulawula ioyile kunokubangela ukuba uxinzelelo lweoyile lungahlali kakuhle, nto leyo ebangela ukuthambisa okwaneleyo xa uqalisa injini okanye ukuma ngequbuliso ngexesha lokusebenza.
I-Youdaoplaceholder0 Uxinzelelo lweoyile olungaqhelekanga : Iziphene zinokubangela ukuba uxinzelelo lweoyile lube phezulu kakhulu okanye lube phantsi kakhulu. Xa uxinzelelo lweoyile luphezulu kakhulu, iingxaki ezifana nomxube otyebileyo kakhulu, umsi omnyama ovela kumbhobho wokukhupha umoya, kunye namandla anganeleyo zinokwenzeka. Uxinzelelo lweoyile oluphantsi lunokubangela ukusetyenziswa ngokukhawuleza kweoyile yenjini kunye nengxolo eyandayo yenjini.
Ukwehla kokusebenza kwamandla e-Youdaoplaceholder0: Isithuthi sinokukhawuleza okubuthathaka, impendulo ye-throttle ecothayo okanye ukushukuma xa sikhawuleza ngokukhawuleza. Oku kungenxa yokunikezelwa kwamafutha okungazinzanga okuvela kwipompo yeoyile, okuchaphazela amandla enjini.
I-Youdaoplaceholder0 Ingxolo engaqhelekanga kunye nokungcangcazela : Injini inokukhupha isandi sokugquma esiqhubekayo okanye ingxolo engaqhelekanga yangaphakathi, ehamba nokungcangcazela okungasebenziyo okanye ukungcangcazela kwenjini ngexesha lokuqhuba. Oku kungenxa yokungqubana okungaqhelekanga kwezinto ezibangelwa kukuthambisa okungekho semgangathweni.
I-Youdaoplaceholder0 Ukusetyenziswa kwepetroli okwandileyo kunye nesibane sesilumkiso esikhanyayo: Ukunikezelwa kwepetroli kusenokungachaneki ngenxa yeengxaki zoxinzelelo lweoyile, nto leyo ebangela ukusetyenziswa kwepetroli okwandileyo; Okwangoku, iyunithi yolawulo lwenjini iya kubona into engaqhelekanga kwaye ikhanyise isibane sephutha (njengesibane sephutha lenjini).
Ukuba kuvela ezi mpawu zingasentla, kucetyiswa ukuba injini ihlolwe kwaye ilungiswe kwangethuba ukuze kuthintelwe umonakalo ongakumbi kwinjini. Xa kusenziwa uhlolo, kufuneka kuqwalaselwe ngokukodwa uxinzelelo lweoyile, imeko yenkqubo yepetroli kunye nemeko yokusebenza kwevalvu yokulawula ngokwayo.
