I-Favourite Factory Delivery Valve 504660 yama-Simms Minimec Pumps

Iphampu yomjovo 'yinhliziyo' yenjini uma kukhona ukwehluleka kuzokwenza ukuthi injini ingasebenzi kahle Iphampu yokuphakela uphethiloli enomfutho ophezulu wengcindezi iyingxenye ebalulekile yesistimu yomjovo kajantshi wengcindezi ephezulu ukuze umjovo womjovo onengcindezi ephezulu unikeze ukuzinza nokuqhubekayo. high-pressure fuel injector pump plunger movement in the process of high-frequency movement of the outlet valve kuthinta ukuthembeka nokuzinza kwevalvu lapho uphethiloli womfutho ophezulu ukuvuza endaweni evalekayo ꎬ ukucindezela kukaphethiloli okunganele ꎬ uhlelo lwesitimela oluvamile. Lapho uphethiloli wengcindezi ephezulu uvuza endaweni evalekayo, umfutho kaphethiloli ohlelweni lukaloliwe oluvamile ayanele, okuholela ekucindezelekeni komjovo onganele we-injector kanye ne-atomisation engeyinhle, okuholela kabi emandleni enjini aphansi noma ngisho nokwehluleka ukuqala. Kuleli phepha, ukuze kuxazululwe inkinga yokwehluleka kokuvalwa kokuvalwa kwe-high-pressure sealing surface okubangelwa yi-cavitation ku-valve yokuphuma, sihlaziya ukwakheka kwe-valve yokuphuma futhi sandise ukwakheka kwe-valve ngokusebenzisa izibalo ze-finite-element simulation kanye nokuhlolwa ukuze kuqinisekiswe. ukuthi umklamo owenziwe kahle uyasebenza ekuxazululeni inkinga ye-cavitation.

I-valve yokuphuma itholakala engxenyeni engenhla ye-plunger yepompo yomjovo futhi ixhunywe ku-accumulator ye-high-pressure accumulator. I-valve yokuphuma iyi-valve yendlela eyodwa futhi uphethiloli ungadlulela ohlangothini olulodwa kuphela nakwelinye icala, elingavala uphethiloli ocindezela kakhulu. Isakhiwo kanye nenqubo yokusebenza ye-valve yokuphuma imi kanje: lapho ikhamera izungeza engxenyeni eyisicaba yephrofayela yekhamera, i-plunger iya phansi futhi ukucindezela okungalungile kukhiqizwa ekamelweni le-plunger. Uma umehluko wengcindezi phakathi kwe-inlet ne-plunger chamber ufinyelela ukucindezela kokuvula kwe-valve, lapho-ke i-spool ye-inlet ihamba phansi, i-valve izovuleka futhi uphethiloli uzofakwa empompini ehlinzekayo nge-spool yokungena. Lapho ikhamera izungeza ukuya kumugqa ophakanyisiwe we-plunger ukunyakaza okuya phezulu kwevolumu yegumbi lokusebenza iba ingcindezi encane yegumbi ikhuphuka ngokushesha lapho indawo yokucindezela ephezulu yegumbi ivula i-valve yokukhipha i-spool ukugeleza kukaphethiloli okunomfutho ophezulu ukuya epayipini lesitimela elivamile lapho ipulangwe isuka phansi iye phezulu. inqubo yokumpompa yokuma ephezulu isiphelile inqubo yokuphindaphinda yepompo ye-plunger yokukhipha i-valve spool ukushintsha umfutho kaphethiloli ovamile endaweni enkulu yokuvala ingcindezi ephezulu okuthambekele ku-cavitation kuholele endaweni yokukhipha uphawu lokuvalwa kwe-valve ye-spalling sealing surface. I-valve kawoyela evala i-valve ye-valve kawoyela evala uphawu, i-flaking sealing surface, ukwehluleka ukuvala ukuxega kwenjini ye-diesel ephehla amandla enziwa emhlabeni yenzeka enanini lepompo yokukhipha umjovo we-valve cavitation test ukwehluleka ukubekezela amahora angama-500 okuvala ingcindezi ephezulu kokuvuleka kwe-valve yokukhipha, ukuvala uphawu. inkinga yokwehluleka ingaphansi kakhulu kwezidingo zempilo yejeneretha evame ukusetshenziswa
