限压阀一般由阀体（椎形、球形）、阀座、调节弹簧、调压螺钉和锁紧螺母以及密封垫圈等零件组成。 限压阀的工作原理是：FE2 GK在大多数时间里，限压阀处于关闭状态，只有当工作介质的压力超过一定数值时，限压阀开启，从旁路排泄一部分介质，使系统内的压力降低；当系统的压力达到下，限压阀关闭，系统的压力又上升。如此周而复始调节，使系统内的介质压力经常处在一个合理水平上，燃油系统、润滑系统、冷却系统和液压系统工作正常。 5#阀板 11E-505757 柱塞 2 418 455 289 泵总成 2643B319 泵总成 2644H201 电磁阀 0 445 110 519 电磁阀 F00VC30318 F00VC30319 油嘴 0 433 172 082 DLLA82P1773 油嘴 0 433 172 102 DLLA150P1808 油嘴 DLLA152P862 油嘴 DLLA145P2301 0 433 172 301 油嘴 DLLA144P2341 计量阀 0 928 400 617 限压阀 1110010028 喷油器 0 445 120 153 喷油器 0 445 120 142 泵总成 4M41 ME190711 ME204338 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=1645404916525&bpp=2&bdt=36&idt=27&shv=r20220216&mjsv=m202202090102&ptt=9&saldr=aa&cookie=ID%3D138bd4a5c3f9dd5c-22e6327ab7c8007c%3AT%3D1621323454%3ART%3D1621323454%3AS%3DALNI_MZr6w-L6tDY0HVf8PxDU64fYTf-Jg&nras=1&correlator=5079969096588&frm=23&ife=1&pv=1&ga_vid=1456388996.1645404917&ga_sid=1645404917&ga_hid=1454277505&ga_fc=0&nhd=1&u_tz=480&u_his=22&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%2C31064036%2C31063246%2C21067496%2C31062931&oid=2&pvsid=2465170338174727&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=1.3uac6w7zg25v&fsb=1&dtd=32" data-google-container-id="1.3uac6w7zg25v" data-load-complete="true"> |
