这种现象往往是机油限压阀泄漏,造成机油压力过低,在摩擦副内难以形成有效的润滑油膜,因此引起烧瓦。 对于液压系统的限压阀,如果工作装置升举不灵,大油门时才能升起,FE2 GK稍一降低油门就自动沉降,有时还可以听到漏油的声音,说明液压系统的限压阀存在泄漏故障。 对于燃油箱上的真空减压阀(实质是进气阀),可以使用手持式真空泵进行检测,其检测方法是:先将真空减压阀阀体清洗干净,然后连接手持式真空泵,检查该阀门的开启压力和真空度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=1645405137232&bpp=1&bdt=31&idt=29&shv=r20220216&mjsv=m202202090102&ptt=9&saldr=aa&cookie=ID%3D138bd4a5c3f9dd5c-22e6327ab7c8007c%3AT%3D1621323454%3ART%3D1621323454%3AS%3DALNI_MZr6w-L6tDY0HVf8PxDU64fYTf-Jg&nras=1&correlator=6661554409072&frm=23&ife=1&pv=1&ga_vid=455693477.1645405137&ga_sid=1645405137&ga_hid=2032215955&ga_fc=0&nhd=1&u_tz=480&u_his=30&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=42531398%2C44750773%2C182982000%2C182982200%2C21067496%2C31062931&oid=2&pvsid=1332625572044349&pem=146&tmod=875727929&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=1.4obbxi4i474c&fsb=1&dtd=34" data-google-container-id="1.4obbxi4i474c" data-load-complete="true"> 柴油涡轮增压器 28231-4A700 燃油滤清器 31922-2E900 燃油滤清器 31922-2B900 柴油机风扇皮带 25212-27400 气流-传感器总成 28164-27800 气流-传感器总成 28138-2B200 喷油器 9709500-522 喷油器 23670-09430 控制阀 094040-0150 CAT修理包 249-0713 油嘴 DLLA158P2318 喷油器 33800-27800 0 445 110 253 喷油器 33800-42010 喷油器 33800-42600 喷油器 35310-37150 喷油器 095000-0940 喷油器 095000-0941 喷油器 0 445 120 346 喷油器 0 445 110 694 |
