Isimiso semishini yepompo likawoyela
Uwoyela wokucindezela uwoyela
Ukumunca uwoyela kanye nomfutho kawoyela wephampu yomjovo kuqedwa ukunyakaza okuphindaphindayo kwe-plunger kumkhono we-plunger. Lapho i-plunger isendaweni engezansi, izimbobo ezimbili zikawoyela emkhonweni we-plunger ziyavulwa, futhi ingaphakathi lomkhono we-plunger lixhunyaniswa nephaseji likawoyela emzimbeni wepompo, futhi uphethiloli ugcwala ngokushesha ngegumbi likawoyela. . Lapho i-CAM ihlezi ku-roller yomzimba we-roller, i-plunger iyakhuphuka. Hambisa phezulu kusukela ekuqaleni kwe-plunger kuze kube yilapho imbobo kawoyela ivinjwa ubuso obungaphezulu besiphetho se-plunger. Phakathi nalesi sikhathi sesikhathi, ngenxa yokuhamba kwe-plunger, uphethiloli ucindezelwa ngaphandle kwekamelo lamafutha futhi ugeleza emgudwini wamafutha. Ngakho-ke le lift ibizwa ngokuthi i-pretravel. Lapho i-plunger ivimba imbobo kawoyela, inqubo yokucindezela uwoyela iyaqala. Lapho i-plunger ikhuphuka, umfutho kawoyela egumbini likawoyela ukhuphuka kakhulu. Lapho ukucindezela kudlula umthombo wasentwasahlobo we-valve yokukhipha uwoyela kanye nomfutho wamafutha ongaphezulu, i-valve kawoyela iphushwa ngaphandle, futhi uphethiloli ucindezelwa epayipini likawoyela bese uthunyelwa kumjovo wamafutha.
Isikhathi lapho imbobo yokungena kawoyela kumkhono we-plunger ivinjwe ngokuphelele ubuso obungaphezulu besiphetho se-plunger ibizwa ngokuthi iphoyinti lokuqala lokuhlinzeka ngowoyela. Lapho i-plunger iqhubeka nokukhuphuka, ukunikezwa kukawoyela kuyaqhubeka, futhi inqubo yokucindezela kawoyela iyaqhubeka kuze kube yilapho i-helical bevel ku-plunger ivula imbobo kawoyela. Lapho imbobo kawoyela ivulwa, uwoyela onengcindezi ephezulu ugeleza usuka egumbini likawoyela udlule endaweni eyilongitudinal ku-plunger kanye nembobo yokubuyisela uwoyela kumkhono we-plunger ukuya ephaseji likawoyela emzimbeni wephampu. Ngalesi sikhathi, umfutho kawoyela wegumbi likawoyela elinomkhono we-plunger wehla ngokushesha, i-valve yokukhipha uwoyela ibuyela esihlalweni se-valve ngaphansi kwesenzo sokucindezela kwamafutha entwasahlobo kanye neshubhu lomfutho ophezulu, futhi umjovo uyeka ngokushesha ukufafaza uwoyela. Ngalesi sikhathi, nakuba i-plunger iqhubeka nokukhuphuka, ukunikezwa kukawoyela kunqanyuliwe. Isikhathi lapho imbobo yokubuyisela uwoyela kumkhono we-plunger ivulwa ngasohlangothini lwe-bevel ye-plunger ibizwa ngokuthi iphoyinti lokugcina lokunikezwa kukawoyela. Kuyo yonke inqubo yokuya phezulu kwe-plunger, ingxenye ephakathi kuphela ye-stroke iyinqubo yokucindezela kwamafutha, okubizwa ngokuthi i-stroke ephumelelayo ye-plunger.
Ukulawula amafutha
Ukuze kuhlangatshezwane nezidingo zomthwalo wenjini ye-diesel, ukunikezwa kukaphethiloli kwephampu yomjovo kaphethiloli kufanele kukwazi ukulungisa phakathi kwebanga lomthamo omkhulu kaphethiloli (umthwalo ogcwele) ukuya ku-zero fuel supply (stop). Ukulungiswa kokunikezwa kukaphethiloli kubonakala ngenduku yezinyo kanye nomkhono ozungezayo ukwenza wonke ama-plungers wepompo yomjovo kaphethiloli ajikeleze ngesikhathi esisodwa. Lapho i-plunger ijikeleza, isikhathi sokuqala sokunikezwa kukawoyela asishintshi, futhi isikhathi sokuphela sokunikezwa kukawoyela siyashintshwa ngenxa yoshintsho endaweni yembobo yokubuyisela uwoyela yomkhono we-plunger ohlangothini lwe-bevel lwe-plunger. Nge-Engeli ehlukile yokuzungezisa i-plunger, i-stroke esebenzayo ye-plunger ihlukile, futhi ukunikezwa kukawoyela kuyashintshwa.
Uma i-Engeli yokuzungezisa ye-plunger inkulu ngokungabi bikho kukawoyela ileveli 1, iba nkulu ibanga phakathi kobuso obuphezulu be-plunger kanye ne-hypotenuse yembobo yokubuyisela uwoyela yomkhono wepulaki evulekile, futhi kuba mkhulu ukunikezwa kukawoyela. Uma i-engeli yokuzungezisa ye-plunger incane, ukunqanyulwa kukawoyela kuqala ngaphambi kwesikhathi futhi ukunikezwa kukawoyela kuba kuncane. Uma injini ye-diesel imiswa, uwoyela kufanele unqanyulwe. Ngenxa yalesi sizathu, i-longitudinal groove ku-plunger ingaphendulelwa emgodini wokubuyisela uwoyela ngokuphambene ngqo nomkhono we-plunger. Ngalesi sikhathi, ku-stroke yonke ye-plunger, uphethiloli osemkhonweni we-plunger ubelokhu egeleza ebuyela esiteshini samafutha ngokusebenzisa i-longitudinal groove kanye nembobo yokubuyisela uwoyela, ayikho inqubo yokucindezela uwoyela, ngakho-ke ukunikezwa kwamafutha kuyalingana no-zero. Lapho i-plunger izungeza, isikhathi sokushintsha indawo yokugcina uwoyela sisetshenziswa ukulungisa ukunikezwa kukawoyela, okubizwa ngokuthi indlela yokulungisa indawo yokugcina uwoyela.
Ukunikezwa kukawoyela kwephampu kawoyela kufanele kuhlangabezane nezidingo zenjini yedizili ezimeni ezahlukahlukene zokusebenza, ngokuya ngezidingo zenjini yedizili, iphampu yamafutha kufanele iqinisekise ukuthi ukunikezwa kukawoyela kwesilinda ngasinye kuqala ngasikhathi sinye, okungukuthi, i-Angle yokunikezwa kwamafutha kusengaphambili iyahambisana, kufanele futhi iqinisekise ukuthi ubude bokunikezwa kwamafutha buyafana, futhi ukunikezwa kwamafutha kufanele kuqale ngokushesha, kumise uwoyela ngokushesha futhi ngobunono, ukugwema ukuconsa. Ngokuya ngesimo segumbi elivuthayo kanye nendlela yokwakheka kwengxube, ipompo yamafutha kufanele inikeze uphethiloli ngokucindezela okwanele kumjovo ukuze kuqinisekiswe ikhwalithi enhle ye-atomization.
