Isimiso somshini wepompo kawoyela
Uwoyela wokucindezela ukumunca uwoyela
Ukumuncwa kwamafutha kanye nokucindezela kwamafutha kwephampu yokujova kuqedwa ngokunyakaza okuphindaphindayo kwephampu emphethweni wephampu. Uma iphampu isendaweni engezansi, imigodi emibili kawoyela emphethweni wephampu iyavulwa, futhi ingaphakathi lephampu yephampu lixhunyaniswa nokuhamba kwamafutha emzimbeni wephampu, futhi uphethiloli ugcwaliswa ngokushesha ngegumbi lamafutha. Lapho i-CAM ihlezi phezu kwerola yomzimba wephampu, iphampu iyaphakama. Hamba uye phezulu kusukela ekuqaleni kwephampu kuze kube yilapho imbobo kawoyela ivinjiwe ubuso obuphezulu bephampu. Phakathi nalesi sikhathi, ngenxa yokunyakaza kwephampu, uphethiloli ucindezelwa uphume ekamelweni lamafutha bese ugeleza uye endaweni yamafutha. Ngakho-ke lokhu kuphakamisa kubizwa ngokuthi i-pretravel. Lapho iphampu ivimba imbobo kawoyela, inqubo yokucindezela uwoyela iyaqala. Lapho iphampu ikhuphuka, ukucindezela kwamafutha emphethweni kawoyela kukhuphuka kakhulu. Lapho ukucindezela kudlula intwasahlobo ye-valve yokuphuma kawoyela kanye nokucindezela kwamafutha okuphezulu, iphampu kawoyela iyacindezelwa, bese uphethiloli ucindezelwa epayipini kawoyela bese uthunyelwa ku-injector kawoyela.
Isikhathi lapho imbobo yokungena kawoyela esikhaleni se-plunger ivinjwe ngokuphelele ubuso obuphezulu be-plunger ibizwa ngokuthi indawo yokuqala yokuphakelwa kawoyela. Lapho i-plunger iqhubeka nokukhuphuka, ukuphakelwa kawoyela kuyaqhubeka, futhi inqubo yokucindezela kawoyela iyaqhubeka kuze kube yilapho i-bevel e-helical e-plunger ivula imbobo kawoyela. Lapho imbobo kawoyela ivuliwe, uwoyela ocindezelekile ophezulu ugeleza usuka ekamelweni likawoyela udlule emseleni omude ku-plunger kanye nembobo yokubuyela kawoyela esikhaleni se-plunger uye endaweni yamafutha emzimbeni wephampu. Ngalesi sikhathi, ukucindezela kawoyela kwegumbi likawoyela esikhaleni se-plunger kwehla ngokushesha, i-valve yokuphuma kawoyela iwela esihlalweni se-valve ngaphansi kwesenzo sokucindezela kawoyela entwasahlobo kanye nepayipi lokucindezela okuphezulu, futhi i-injector iyeka ngokushesha ukufafaza uwoyela. Ngalesi sikhathi, yize i-plunger iqhubeka nokuphakama, ukuphakelwa kawoyela sekuphelile. Umzuzu lapho imbobo yokubuyela kawoyela esikhaleni se-plunger ivulwa ohlangothini lwe-bevel lwe-plunger ibizwa ngokuthi indawo yokugcina yokuphakelwa kawoyela. Kuyo yonke inqubo yokunyakaza okuphezulu kwe-plunger, ingxenye ephakathi kuphela ye-stroke yinqubo yokucindezela uwoyela, ebizwa ngokuthi i-stroke ephumelelayo ye-plunger.
Ukulawulwa kukaphethiloli
Ukuze kuhlangatshezwane nezidingo zomthwalo wenjini kadizili, ukunikezwa kukaphethiloli kwephampu yokujova uphethiloli kumele kukwazi ukulungisa ngaphakathi kobubanzi bokunikezwa kukaphethiloli okuphezulu (umthwalo ogcwele) kuya ekunikezelweni kukaphethiloli okungu-zero (ukuma). Ukulungiswa kokunikezwa kukaphethiloli kuqashelwa yinduku yamazinyo kanye nesikhwama esijikelezayo ukuze kwenze wonke ama-plunger ephampu yokujova uphethiloli ajikeleze ngesikhathi esisodwa. Lapho i-plunger ijikeleza, isikhathi sokuqala kokunikezwa kukaphethiloli asishintshi, futhi isikhathi sokuphela kokunikezwa kukaphethiloli siyashintshwa ngenxa yokushintsha kwesikhundla sembobo yokubuya kukaphethiloli yesikhwama se-plunger ohlangothini lwe-bevel lwe-plunger. Nge-Engela ehlukile yokujikeleza kwe-plunger, ukushaywa okusebenzayo kwe-plunger kuhlukile, futhi ukunikezwa kukaphethiloli nakho kuyashintshwa.
Uma i-engeli yokujikeleza kwe-plunger ikhulu kakhulu ezingeni 1 lokunikezwa kwamafutha, ibanga eliphakathi kobuso obuphezulu be-plunger kanye ne-hypotenuse yembobo yokubuyisa amafutha yesleeve evulekile ye-plug, kanye nokunikezwa kwamafutha kukhulu. Uma i-engeli yokujikeleza kwe-plunger incane, ukunqunywa kwamafutha kuqala kusenesikhathi futhi ukuhlinzekwa kwamafutha kuncane. Lapho injini yedizili imisiwe, uwoyela kumele unqunywe. Ngenxa yalesi sizathu, umsele omude ku-plunger ungaphendulwa uye emgodini wokubuyisa uwoyela ngqo maqondana nesleeve ye-plunger. Ngalesi sikhathi, kulo lonke i-plunger stroke, uphethiloli kusleeve se-plunger ubulokhu ugeleza ubuyela emuva esiteshini samafutha nge-groove ende kanye nembobo yokubuyisa uwoyela, akukho nqubo yokucindezela uwoyela, ngakho ukuhlinzekwa kwamafutha kulingana no-zero. Lapho i-plunger ijikeleza, isikhathi sokushintsha iphuzu lokugcina lokuhlinzekwa kwamafutha sisetshenziselwa ukulungisa ukuhlinzekwa kwamafutha, okubizwa ngokuthi indlela yokulungisa iphuzu lokugcina lokuhlinzekwa kwamafutha.
Ukunikezwa kukawoyela kwephampu kawoyela kufanele kuhlangabezane nezidingo zenjini kadizili ezimweni ezahlukene zokusebenza, ngokwezidingo zenjini kadizili, iphampu kawoyela kufanele iqinisekise ukuthi ukunikezwa kukawoyela kwesilinda ngayinye kuqala ngesikhathi esifanayo, okungukuthi, i-Angle yokunikezwa kukawoyela iyahambisana, kufanele futhi iqinisekise ukuthi isikhathi sokunikezwa kukawoyela siyafana, futhi ukunikezwa kukawoyela kufanele kuqale ngokushesha, kumise uwoyela ngokushesha nangokucophelela, ukuze kugwenywe ukuconsa. Kuye ngesimo segumbi lokushisa kanye nendlela yokwakheka kwengxube, iphampu kawoyela kumele inikeze uphethiloli ngokucindezela okwanele ku-injector ukuqinisekisa ikhwalithi enhle ye-atomization.
I-Zhuo Meng Shanghai Auto Co., Ltd. izibophezele ekuthengiseni izingxenye zezimoto ze-MG&MAUXS futhi wamukelekile ukuzithenga.
