发动机在工作中，从喷油泵泵出的高压柴油往往会夹带一些杂质进入喷油嘴，并黏附在针阀体的密封锥面上，使其密封不严。由于燃烧室内高压、高温气体的烧蚀，再加上燃油中机械杂质的频繁冲刷，针阀与针阀体的密封环面出现麻点和凹坑，致使喷油嘴针阀与针阀体之间的密封性能因磨损而恶化，于是可能会出现上述故障。 出油阀圆柱形的减压带与阀座配合部位磨损，FE2 GK且减压带和阀座上端磨成锥形，配合间隙超限，当喷油泵工作时，减压带就不会全部露出阀座，从而提高了高压油管的残余应力，破坏了整个油管的工作。LED">ABSolute;top:0;border:0;width:undefinedpx;height:undefinedpx;" SANdbox="allow-forms allow-popUPS allow-popups-to-escape-sandbox allow-same-origin allow-scripts allow-top-navigation-by-user-activation" frameborder="0" marginwidth="0" marginheight="0" vspace="0" hspace="0" allowtransparency="true" scrolling="no" src="https://googleads.g.doubleclick.net/pagead/ads?client=ca-pub-6745515041074118&ouTPUt=html&adk=1812271804&adf=3279755396&plat=3%3A32%2C4%3A32%2C8%3A134217728%2C9%3A134250632%2C16%3A8388608%2C17%3A32%2C24%3A32%2C25%3A32%2C30%3A1081344%2C32%3A32&format=0x0&url=https%3A%2F%2Fwww.bizrobot.com%2Fcompany_bloginfo.php%3Fact%3D1&ea=0&flash=0&pra=5&wgl=1&uach=WyJXaW5kb3dzIiwiNy4wLjAiLCJ4ODYiLCIiLCI5OC4wLjQ3NTguMTAyIixbXSxudWxsLG51bGwsIjY0IixbWyIgTm90IEE7QnJhbmQiLCI5OS4wLjAuMCJdLFsiQ2hyb21pdW0iLCI5OC4wLjQ3NTguMTAyIl0sWyJHb29nbGUgQ2hyb21lIiwiOTguMC40NzU4LjEwMiJdXV0.&dt=1645494053435&bpp=4&bdt=41&idt=26&shv=r20220216&mjsv=m202202090102&ptt=9&saldr=aa&cookie=ID%3D138bd4a5c3f9dd5c-22e6327ab7c8007c%3AT%3D1621323454%3ART%3D1621323454%3AS%3DALNI_MZr6w-L6tDY0HVf8PxDU64fYTf-Jg&nras=1&correlator=2963895380995&frm=23&ife=1&pv=1&ga_vid=1358290196.1645494053&ga_sid=1645494053&ga_hid=1084138701&ga_fc=0&nhd=1&u_tz=480&u_his=14&u_h=1080&u_w=1920&u_ah=958&u_aw=1920&u_cd=24&u_sd=1&DMC=8&adx=-12245933&ady=-12245933&biw=1920&bih=855&isw=730&ish=360&ifk=2699508910&scr_x=0&scr_y=0&eid=42531397%2C44750773%2C182982000%2C182982200%2C31064858%2C44756431%2C21067496%2C31062931&oid=2&pvsid=3812775062359484&pem=146&tmod=656603823&uas=0&nvt=1&ref=https%3A%2F%2Fwww.bizrobot.com%2Fcompany_bloginfo.php%3Fadd_suc%3D1&eae=2&fc=1920&brdim=0%2C0%2C0%2C0%2C1920%2C0%2C1920%2C958%2C730%2C360&vis=1&rsz=%7C%7Cs%7C&abl=NS&fu=32772&bc=31&ifi=1&uci=1.p8k66m88o53j&fsb=1&dtd=33" data-google-container-id="1.p8k66m88o53j" data-load-complete="true"> 泵量孔 095331-0020 喷油器 0 414 720 310 油泵总成 22100-1C050 注射泵 0 440 003 238 油泵总成 44060 修理包 095000-5450 DLLA157P855 修理包 095000-5504 修理包 23670-30050 095000-5880 095000-5881 095000-5660 23670-39095 修理包 095000-5471 095000-5470 095000-5473 095000-5474 095000-5475 095000-8900 095000-8901 095000-8902 095000-6373 095000-8903 095000-0660 (8-98284393-0) 修理包 0 445 120 006 DLLZ157P964 F00RJ00375 修理包 33800-4A600 |
