Iyini ivalvu yokulawula ukugeleza kwephampu kawoyela yemoto
Umsebenzi wevalvu yokulawula ukugeleza kwephampu kawoyela yezimoto ukukhawulela ukugeleza okuphezulu kwephampu kawoyela, ukuqinisekisa ukuqina kwengcindezi kawoyela nokuvikela uhlelo lokuthambisa injini. Lokhu okulandelayo yimisebenzi nezimiso ezithile:
Umsebenzi oyinhloko
Nciphisa izinga lokugeleza eliphezulu: Ngokulungisa inani lokukhishwa kukawoyela yipompo kawoyela, vimbela ukugeleza ngokweqile ngenxa yesivinini esikhulu senjini, futhi ugweme ukushisa ngokweqile kwepompo kawoyela noma imfucuza kagesi.
Gcina ingcindezi izinzile: Lapho ijubane lenjini lishintsha, ivalvu yokulawula ilungisa ngokuzenzakalelayo izinga lokugeleza ukuqinisekisa ukuthi ingcindezi kawoyela ihlala ngaphakathi kwebanga elifanele futhi ihlangabezana nezidingo zokuthambisa zenjini.
Isimiso sokusebenza
Ukuxhumana nesivinini senjini: Izinga lokugeleza kwepompo kawoyela livame ukulingana nesivinini senjini, kodwa ivalvu yokulawula izozivumelanisa ngokuguquguqukayo ngokwezidingo zangempela ukuze igweme ukugeleza okunganele lapho ingasebenzi noma lapho igeleza ngokweqile ngesivinini esikhulu.
Indlela yokulawula ingcindezi: Amanye ama-valve okulawula athola impendulo yengcindezi ngama-valve anciphisa ingcindezi noma izakhiwo ze-diaphragm (njengezilawuli zengcindezi kaphethiloli). Lapho ingcindezi idlula inani elibekiwe, uwoyela owengeziwe ugeleza ubuyela endaweni yokungena kawoyela noma ethangini likaphethiloli.
Izimo ezijwayelekile zohlelo lokusebenza
Uhlelo lokuthambisa injini: Luqinisekisa ukuthi uwoyela wenjini unganikeza ingcindezi eqinile ngaphansi kwezimo zesivinini esiphezulu nesiphansi, okunciphisa ukuguguleka.
Vimbela ukugcwala ngokweqile kwephampu kawoyela: Gwema ukulimala kwemishini kuphampu kawoyela noma ukwanda okungavamile kwezinga lokushisa likawoyela ngenxa yokugeleza ngokweqile.
Umsebenzi oyinhloko wevalvu yokulawula ukugeleza kwephampu kawoyela wezimoto ukukhawulela ingcindezi ephezulu yesistimu yokugcoba, ukuvimbela umonakalo ezingxenyeni zokugcoba noma ukuvuza kukawoyela endaweni kawoyela ngenxa yengcindezi enkulu. Okulandelayo ukuhlaziywa komsebenzi othize:
Umsebenzi oyinhloko
Umkhawulo wokucindezela: Ngokulungisa ingcindezi yokukhipha yepompo kawoyela, qiniseka ukuthi uhlelo lokugcoba lusebenza ngaphakathi kwebanga eliphephile futhi uvimbele izingxenye ekulimaleni ngenxa yokucindezela okuphezulu.
Ukuvikelwa kokuvuza kukawoyela: Lapho ingcindezi yesistimu ikhuphuka ngendlela engavamile, ivalvu yokulawula izokhipha ingcindezi ngokuzenzakalelayo ukuvimbela ukwehluleka kophawu lokudlula kukawoyela kanye nokuvuza kukawoyela.
Umehluko kwamanye ama-valve okulawula
Ngokungafani nevalvu yokulawula ukugeleza kwephampu kawoyela wokuqondisa, eyenzelwe ngqo izinhlelo zokugcoba, ivalvu yokulawula yephampu kawoyela wokuqondisa isetshenziselwa ukukhawulela ukugeleza kwesistimu yokuqondisa yamandla.
Ngokungafani nevalvu yokulawula iphampu kaphethiloli, elawula kakhulu ingcindezi kaphethiloli, ivalvu yokulawula iphampu kaphethiloli yenzelwe ingcindezi kaphethiloli.
Izimo ezijwayelekile zohlelo lokusebenza
Amavalvu okulawula ipompo kawoyela avame ukutholakala ezinhlelweni zokugcoba injini, ikakhulukazi kumamodeli anezidingo zokugcoba ezicindezela kakhulu (njengezinjini zedizili noma izimoto ezisebenza kahle kakhulu).
Ukungasebenzi kahle kwevalvu yokulawula ukugeleza kwephampu kawoyela wemoto kungaholela ekucindezelweni kawoyela okungajwayelekile, amandla enjini anganele, umsindo ongajwayelekile kanye nezinye izinkinga, futhi kudinga ukulungiswa ngesikhathi. Lokhu okulandelayo yizibonakaliso ezithile kanye nemiphumela:
Ukubonakaliswa kwamaphutha okuvamile
Umfutho kawoyela ongajwayelekile: Isibani sokuxwayisa ngomfutho kawoyela kudeshibhodi sivuliwe, okungase kuhambisane nomfutho kawoyela ophezulu kakhulu noma ophansi kakhulu.
Umsindo wenjini ongajwayelekile: I-piston, i-crankshaft nezinye izingxenye zikhiqiza imisindo yokungqubuzana okubukhali noma imisindo yokungqongqoza ngenxa yokungagcobi ngokwanele.
Ukwehla kwamandla: Ukusheshisa okubuthakathaka, ukusheshisa okungazelelwe okubangela ukuba imoto iqine, kanye nokusetshenziswa kukaphethiloli okwandisiwe.
Ubunzima bokuqala: Isihluthulelo sidinga ukuphendulwa kaningi ukuze siqale, ikakhulukazi uma imoto ibanda.
Imiphumela emibi kakhulu
Ukushisa ngokweqile kwenjini: Ukungajikelezi kahle kukawoyela wenjini kuholela ekunciphiseni ukusebenza kahle kokushabalalisa ukushisa, okungase kubangele ukusha kwesilinda kanye nokusha kwamabhereyitha.
Ingozi Yokuzishayisa: Ukucindezela kukawoyela okungalawulwa kungabangela ukushisa ngokweqile noma ukwehluleka kokuvala.
Izimbangela ezivamile zamaphutha
Ukulimala kwevalvu ye-solenoid: Kuholela ekuvinjweni kokulethwa kukawoyela futhi kuthinta ukulawulwa kwengcindezi kawoyela.
Ukuguguleka kwezingxenye: Ukungatholakali kahle kukaphethiloli kubangelwa ukuguguleka kwezingxenye ezifana ne-plunger sleeve kanye ne-valve yokuphuma kawoyela.
Ukuvaleka kwesekethe kawoyela: Ukungcola noma uwoyela wenjini osezingeni eliphansi kuvala isikrini sesihlungi, okusheshisa ukuguguleka komzimba wephampu.
Iziphakamiso zokulungisa
Misa imoto ngokushesha ukuze uyihlole ukuze ugweme ukuqhubeka nokushayela nokudala umonakalo omkhulu.
Sebenzisa amathuluzi ochwepheshe ukuhlola ingcindezi kawoyela (njengesilinganiso sokucindezela kukaphethiloli) nokuxazulula izinkinga nge-solenoid valve noma izingxenye zemishini.
Shintsha izingxenye zasefektri zokuqala bese ushintsha njalo isihlungi samafutha ukuze ugweme uwoyela ongemuhle.
Uma ufuna ukwazi okwengeziwe, qhubeka ufunda ezinye izihloko ezikulesi siza!
Sicela usishayele ucingo uma udinga imikhiqizo enjalo.
Inkampani Zhuo Meng Shanghai Auto Co., Ltd. uzibophezele ekuthengiseni i-MG&I-MAXUSizingxenye zezimoto zamukelekile ukuthenga.
