I-Hot Selling ye-Diesel Fuel Common Rail Injector Nozzle G3S151 ye-Common Rail System Spare Parts

1. Ukulungelelaniswa kwendibano engafanelekanga
Okokuqala, ukucocwa phakathi kwe-cylinder kunye ne-piston akuhambelani neemfuno eziqhelekileyo, okubangelwa ukuguqulwa kwendawo ye-piston ring, kwaye indawo yokuvula ayigxininisi, ibangela ukuvuza kweoli kunye negesi kwi-cylinder. Okwesibini, i-shaft engundoqo kunye nokudibanisa intonga ifakwe kwindawo esemgangathweni, okubangela ukuba indawo yokuhlanganisana ingahambelani neemfuno eziqhelekileyo, kwaye i-torque yokuqinisa kunye nokucoca ayihambelani nomgangatho, obangela ukutshisa kunye nokugqoka. Okwesithathu, igiya yexesha lifakwe kwindawo yendibano, echaphazela ubudlelwane be-gear meshing, kwaye ngokuhambelanayo ibangele ukungqubana kwepiston kunye nevalve.
ingxaki. Okwesine, ukucocwa kwevalve akuhambelani nomgangatho, okuchaphazela ukuqina kwevalve, enokuthi itshise ivalve kunye nezinye iindawo, kwaye ikhawulezise ukunxiba kweendawo zevalve. Okwesihlanu, ukubonelela kunye nexesha le-cylinder nganye azilingani, ezinokuchaphazela ngokulula ukuzinza kwe-injini ye-diesel kwaye kubangele iingxaki zokutsha ezingaphelelanga.
2. I-injini ye-diesel ayikwazi ukuqalisa ngokuqhelekileyo
Okokuqala, khangela i-low-pressure oil circuit. Nika ingqalelo ekujongeni ukutshitsha kwedizili ezantsi kwetanki yedizili ukuqinisekisa ukuba ikwimeko evulekileyo. Sebenzisa ivalve yokukhupha i-drain ukususa ngokupheleleyo i-oyile emdaka kunye namanzi etankini. Ngexesha elifanayo, khangela kwaye ukhuphe ioli engcolileyo kunye namanzi kwi-filter kunye ne-diesel filter. I-screw ye-bleed phezu kwe-high-pressure body pump kufuneka ikhululwe ngokufanelekileyo. Sebenzisa impompo ye-oyile yesandla ukumpompa ioyile, kwaye ujonge imeko yobonelelo lweoyile ephantsi koxinzelelo ngaxeshanye ukuqinisekisa ukuba yanele kwaye igudile. Ukuba ayigudi kwaye ayanelanga, oko kuthetha ukuba kukho umoya oshiyekileyo ngaphakathi. Igcisa kufuneka lijonge onke amakhonkco ombhobho phambi kwempompo ye-oyile yesandla ukujonga iindawo ezivuzayo. Xa impompo ye-oyile yesandla isetyenziselwa ukumpompa i-oyile, ukuba i-oyile inzima ukungena kwaye ukufunxa kwe-oyile ayigudi, oko kuthetha ukuba kukho ukuvaleka kwisekethe ye-oyile ephantsi koxinzelelo, kunye nescreen sokucoca idizili, into yokucoca. , kwaye ukuvaleka kwemibhobho kufuneka kuhlolwe. Xa iqondo lobushushu lisezantsi, i-brand ye-diesel kufuneka ihlolwe ukunqanda ukuvaleka kweesekethe ze-oyile ngenxa ye-wax yemvula yedizili kunye neqhwa lamanzi. Xa kusenzeka ingxaki yokuvaleka, impazamo kufuneka isuswe kwangethuba de ukufunxa kwe-oyile kube mpuluswa kwaye nonikezelo lwe-oyile lungenamaqamza. Ukuba iphoso alibangelwa ezi zizathu zingasentla, mhlawumbi i-piston yepompo yeoli yesandla igugile kakhulu, i-valve yonakaliswe, okanye ihlanjululwe ngumbane ngokungcola. Kusenokuba ngenxa yokungatywinwa ngokwaneleyo kwempompo yeoli yesandla, kwaye ipompo yeoli yesandla idinga ukutshintshwa ngeli xesha. Okwesibini, khangela i-high-pressure oil circuit. Xa kungekho siphoso kwi-oyile ye-low-pressure circuit, injini ye-diesel ayikwazi ukuqala ngokuqhelekileyo, kwaye i-high-pressure oil circuit kufuneka ihlolwe. Okokuqala, jonga intonga yohlengahlengiso lweoyile yempompo yoxinzelelo oluphezulu ukuqinisekisa ukuguquguquka kwentonga yegiya yohlengahlengiso ukuyinqanda ukuba ibambeke kwindawo yokumisa. Nika ingqalelo ekujongeni ixesha lokubonelela ngeoyile yempompo yeoli yoxinzelelo oluphezulu. Ukuba ixesha lokunikezelwa kweoli alinangqiqo, kufuneka lilungiswe kwixesha eliqhelekileyo. Nika ingqalelo ekupheliseni umoya ngaphakathi kombhobho weoli woxinzelelo oluphezulu. Xa kukho umoya ngaphakathi kumbhobho we-oyile we-diesel woxinzelelo oluphezulu, awukwazi ukudlula kwisiqalisi ukuqhuba injini yedizili ukujikeleza. Xa uphatha, i-nut edibanisa i-injector kumbhobho we-oyile ephezulu kufuneka ikhululwe, kwaye isiqalo kufuneka siqaliswe ukujikeleza injini ye-diesel. Xa umbhobho we-oyile woxinzelelo oluphezulu unokutshiza i-fuel, i-nut edibanisa umbhobho we-oyile woxinzelelo oluphezulu kufuneka iqiniswe. Xa le ndlela ingentla ingasetyenziselwa ukuqalisa, i-injector kunye nempompo yeoli yoxinzelelo oluphezulu kufuneka ihlolwe. Kungakhathaliseki ukuba zeziphi izixhobo ezingentla zihluleka, umsebenzi wokulinga kufuneka uqhutywe kwibhentshi yokuvavanya, kwaye umvavanyi okhethekileyo woxinzelelo kufuneka asetyenziswe ukuphepha izingozi.
