Diesel Injector Fuel Injector 0445120064 0445120136 0445120137 Bosch for Renault Engine 240 Premium II

Ubulukhuni obuncane bezinhlayiya ezivuzayo zenza ukuthi ukwelashwa kwendawo yasentwasahlobo kungadluli;· Ukuphuka kokukhathala kubala cishe u-1.7% wesamba sokwehluleka, kanti okunye ukuphumula kokukhathala.· Ukuphumula kokukhathala bekulokhu kuyinkinga exakayo imboni yasentwasahlobo.Njengoba izinsimbi zingeyona i-elastomer ngokuphelele, i-micro-deformation (i-creep) izokwenzeka ngisho nangaphansi kwesenzo sokucindezeleka ngaphansi komkhawulo wokunwebeka, futhi umthelela wokuguquguquka unomphela ekwehleni kwengcindezi yokuvula komjovo ngokuvamile ngu-0.5 Beyond MPa, ukwehla kokucindezela ikakhulukazi okubangelwa ukuguga kwebhola lensimbi noma i-sphere emsileni we-valve yenaliti kanye nenduku ye-ejector, futhi ithonya layo ekwehleni kwengcindezi liphakathi kuka-0.5 no-2.5 ​​MPa.

(2) Ukugqokwa kwama-gaskets ayisicaba: (1) Ama-gasket ayisicaba anama-burrs, afika ku-0.4mm;②I-flat gasket material ithambile, insimbi evamile ephansi ye-carbon, kanye nobulukhuni HRC47 ~ 54 othintana nokuphela kwentwasahlobo kulula ukugqokwa nokuguqulwa

(3) induku ye-jacking.Isikulufu esilawula ukucindezela (noma umkhono wesikulufu) kanye nokucindezela kokulawula isikulufu seziphetho ezimbili ukugqokwa kwendiza yobuso obuseduze :40% wesijojo sikaphethiloli sibonakala sigugile lapha.Kunezizathu ezimbili:①ukucutshungulwa kwendawo othintana nayo kulukhuni kakhulu, i-Ra 12.50 Hn, okuholela ekwehleni kwengcindezi engaphezu kuka-1 MPa;(2) Indiza ethintana nayo ayilingani, okubangela ukuthi ubuso bentwasahlobo obungalingani bubangele ukugqokwa kwebhande elikhanyayo, ukujula okuphezulu kufika ku-0.15mm.

(4) Umthelela wokuhlanzeka komjovo kaphethiloli: Ngenxa yokuthi umthelela wokuqothula wemishini yokususa umjovo kaphethiloli wabakhiqizi abaningi basekhaya awukwazi ukuhambisana nezidingo zezindinganiso zikazwelonke, kunenani elithile lezinwele kanye nokucutshungulwa kwe-abrasive emzimbeni womjovo kaphethiloli, okwazi ukuhambisana nezimfuneko zezindinganiso zikazwelonke. kubangela ukuguga okungavamile kwezingxenye zokuhlanganisa umjovo kaphethiloli, okuholela ekwenyukeni kokuqina, ukuwohloka kophawu kanye nokwehla kwengcindezi.
