Umgaqo womatshini wepompo yeoyile
Ioyile yokufunxa uxinzelelo lweoyile
I-oyile yokufunxa kunye noxinzelelo lwe-oyile yempompo yokutofa igqitywe yintshukumo yokubuyisela i-plunger kwi-sleeve ye-plunger. Xa i-plunger ikwindawo esezantsi, imingxuma emibini yeoli kumkhono we-plunger iyavulwa, kwaye umngxuma ongaphakathi womkhono we-plunger unxibelelana nendlela yeoli ekwimpompo yomzimba, kwaye ifutha izaliswa ngokukhawuleza ngegumbi leoli. . Xa i-CAM iphumla kwi-roller ye-roller body, i-plunger iphakama. Shenxisela phezulu ukusuka ekuqaleni kweplunger de umngxuma we-oyile uvalwe bubuso obungasentla beplunger. Ngeli xesha lexesha, ngenxa yokuhamba kwe-plunger, i-fuel ikhutshwe ngaphandle kwegumbi leoli kwaye igeleza kwi-oil passage. Ke oku kunyuswa kubizwa ngokuba yi-pretravel. Xa i-plunger ivala umngxuma we-oyile, inkqubo yokucofa i-oyile iqala. Xa i-plunger inyuka, uxinzelelo lwe-oyile kwigumbi le-oyile luyenyuka ngokukhawuleza. Xa uxinzelelo ludlula i-spring spring ye-valve ye-oyile kunye noxinzelelo lwe-oyile ephezulu, i-valve yeoli ikhutshwe, kwaye i-fuel icinezelwe kwipayipi yeoli kwaye ithunyelwe kwi-injector ye-fuel.
Ixesha apho umngxuma wokungena kwe-oyile kumkhono we-plunger uvalwe ngokupheleleyo bubuso obungasentla be-plunger ibizwa ngokuba yindawo yokuqalisa i-oyile yethiyori. Xa i-plunger iqhubeka ihambela phezulu, ukunikezelwa kweoyile kuyaqhubeka, kwaye inkqubo yoxinzelelo lwe-oyile iyaqhubeka de i-helical bevel kwiplunger ivule umngxuma weoyile. Xa uvula umngxuma we-oyile, i-oyile yoxinzelelo oluphezulu ibaleka isuka kwigumbi le-oyile idlula kwi-longitudinal groove kwi-plunger kunye nomngxuma wokubuyiswa kwe-oyile kumkhono we-plunger ukuya kwipaseji yeoli kumzimba wempompo. Ngeli xesha, uxinzelelo lweoyile yegumbi leoyile ye-plunger yehla ngokukhawuleza, ivalve yokukhupha ioyile ibuyela kwisitulo sevalvu phantsi koxinzelelo lweoyile entwasahlobo kunye netyhubhu yoxinzelelo oluphezulu, kwaye i-injector iyayeka kwangoko ukutshiza ioyile. Ngeli xesha, nangona i-plunger iqhubeka nokunyuka, ukunikezelwa kweoyile kuphelisiwe. Umzuzu xa umngxuma wokubuya kwe-oyile kumkhono weplunger uvulwa kwicala le-bevel leplunger ubizwa ngokuba yindawo yokuphela kobonelelo lweoyile. Kuyo yonke inkqubo yokunyuka kwe-plunger, kuphela indawo ephakathi ye-stroke yinkqubo yoxinzelelo lwe-oyile, ebizwa ngokuba yi-stroke esebenzayo ye-plunger.
Ulawulo lwamafutha
Ukuze kuhlangatyezwane neemfuno zomthwalo we-injini ye-diesel, ukunikezelwa kwepetroli yempompo ye-injection ye-fuel kufuneka ikwazi ukulungelelanisa phakathi koluhlu lwe-fuel unikezelo olupheleleyo (umthwalo ogcweleyo) kwi-zero fuel supply (stop). Ukulungelelaniswa kokunikezelwa kwamafutha kuqondwa ngentonga yezinyo kunye nomkhono ojikelezayo ukwenza zonke iiplungers zepompo yokutofa kwe-fuel zijikeleze ngaxeshanye. Xa i-plunger ijikeleza, ixesha lokuqala lokunikezelwa kwe-oyile alitshintshi, kwaye ixesha lokuphela kwe-oyile litshintshile ngenxa yokutshintsha kwendawo yokubuyisela i-oyile yomngxuma we-plunger kwicala le-bevel ye-plunger. Nge-Angle eyahlukileyo yokujikeleza kwe-plunger, i-stroke esebenzayo ye-plunger iyahluka, kwaye ukunikezelwa kweoli kuyatshintshwa.
Okukhona i-Engile yokujikeleza kweplunger yokungabikho kwe-oyile inqanaba loku-1, kokukhona umgama omkhulu phakathi kobuso besiphelo esiphezulu se-plunger kunye ne-hypotenuse ye-oyile yokubuyisela umngxuma wesingxobo seplagi evulekileyo, kunye nokubonelelwa okukhulu kwe-oyile. Ukuba i-Angle yokujikeleza i-plunger incinci, ukunqunyulwa kwe-oyile kuqala kwangethuba kwaye ukunikezelwa kwe-oyile kuncinci. Xa injini ye-diesel imisiwe, i-oyile kufuneka inqunyulwe. Ngesi sizathu, i-longitudinal groove kwi-plunger inokujikwa kumngxuma we-oyile wokubuyela ngqo ngokuchasene nomkhono weplunger. Ngeli xesha, kuyo yonke i-stroke ye-plunger, i-fuel kwi-sleeve ye-plunger iye yabuyela kumjelo we-oyile ngokusebenzisa i-longitudinal groove kunye ne-oil return hole, akukho nkqubo yoxinzelelo lwe-oyile, ngoko ke ukunikezelwa kweoli kufana ne-zero. Xa i-plunger ijikeleza, ixesha lokutshintsha indawo yokuphela kwe-oyile isetyenziselwa ukulungelelanisa unikezelo lwe-oyile, olubizwa ngokuba yi-oil supply end point adjustment method.
Ukunikezelwa kweoli yepompo yeoli kufuneka kuhlangabezane neemfuno ze-injini ye-diesel kwiimeko ezahlukeneyo zokusebenza, ngokweemfuno ze-injini ye-diesel, ipompo yeoli kufuneka iqinisekise ukuba i-oyile ye-cylinder nganye iqala ngexesha elifanayo, oko kukuthi, i-oyile yokubonelela kwangaphambili i-Angle iyahambelana, kufuneka kwakhona iqinisekise ukuba ixesha lokunikezelwa kweoli liyafana, kunye nokunikezelwa kweoli kufuneka kuqale ngokukhawuleza, ukumisa i-oyile ngokukhawuleza nangokucocekileyo, ukuphepha ukuvuza. Ngokuxhomekeke kwifom yegumbi lokutsha kunye nendlela yokwenza umxube, ipompo yeoli kufuneka inike i-fuel ngoxinzelelo olwaneleyo kwi-injector ukuqinisekisa umgangatho omhle we-atomization.
