ATOS先导型溢流阀故障失灵及造成的原因：先导阀阀芯弹簧折断；阴尼孔堵塞；先导阀阀口密封不良；主阀芯卡死等。相应的排除措施是：更换或在折断处加平垫以应急使用；清洗疏通；研磨或将该油路断路以应急使用；研磨、清洗。限压不稳：先导型溢流阀限压不稳，表现为液压系统压力偏低或偏高，液压执行元件动作无力或油管、泵体、阀体爆裂。造成限压不稳故障的原因：压力调整不当；先导阀阀芯弹簧弯曲或变软；油液过脏或油液流动不畅。相应的排除措施是：重新调整；校正、加垫或更换；更换、清洗。先导型溢流阀限压不稳为渐发性故障，先导型溢流阀失灵为突发性故障，在排除完故障后，应按系统所限定的压力对先导型溢流阀控制的压力重新进行调整。ATOS先导型溢流阀由主阀和先导阀两部分组成。先导阀类似于直动型溢流阀，但一般多为锥阀（或球阀）形阀座式结构。主阀可分为一节同心结构、二节同心结构和三节同心结构。三节同心结构:主阀芯与阀盖、阀体与主阀座等三处有同心配合要求，属于三节同心结构。压力油自阀体中部进油口进入，并主阀芯上阻尼孔进入主阀芯上腔，油阀盖上通道和锥阀座上小孔作用与锥阀上。当进油口压力小于先导阀调压弹簧调定值时，先导阀关闭，主阀芯上、下两侧有效面积比为1.03～1.05，上侧稍大，作用与主阀芯上压力差和主阀弹簧力均使主阀口闭紧，不溢流。当进油压力超过先导阀调定压力时，先导阀被打开，造成资金油口P井主阀芯阻尼孔、先导阀口、主阀芯ZX孔至阀体下部出油口（溢流口）流动。阻尼孔处流动损失使主阀芯上、下腔中油液产生一个随先导阀流量增加而增加压力差，当它主阀芯上、下作用面上产生总压力差足以克服主阀弹簧力、主阀自重和摩擦力时，主阀芯开启。此时进油口与出油口（溢流口）直接相通，造成溢流以保持系统压力。二节同心结构:主阀芯为带有圆柱面锥阀。为使主阀关闭时有良好密封性，要求主阀芯1圆柱导向面和圆锥面与阀套配合良好，两处同心度要求较高，故称二节同心。主阀芯上没有阻尼孔，而将三个阻尼孔分别设阀体和先导阀体上。其工作原理与三节同心先导型溢流阀相同，只油液从主阀下腔到主阀上腔，需三个阻尼孔。根据零件技术要求，进行动力和运动分析，再确定主要参数，液压图形编制，然后拟定液压系统图，进行标准元件选择和专用元件设计，之后验证液压系统技术性能，Z后编制技术文件与审核。ATOS先导型溢流阀特点：1）、具有良好的自适应性能，布局灵活方便；2）、单位功率的重量轻，工作平稳、快速性好；3）、液压元件的可靠性高，使用寿命长；4）、液压系统设计、制造、和使用维护方便；5）、传动效率偏低；6）、造价较高；7）、故障诊断困难；直动式溢流阀RZMA-A-010/250/M21RZMA-A-030/180/M/721RZMO-A-010/100RZMO-A-010/210RZMO-A-010/210/1820RZMO-A-010/315RZMO-A-010/315/18RZMO-A-010/50RZMO-A-010/50/18RZMO-A-030/10020RZMO-A-030/21020RZMO-A-030/210/18RZMO-A-030/315RZMO-AE-010/31510RZMO-AE-030/10040RZMO-P1-010/100/18/MC20RZMO-P1-010/210RZMO-P3-010/100/AM1NSARZMO-P3-010/100/I/AM1NSARZMO-P3-010/210/I/AM1NSRZMO-P3-010/210/I/AMINSARZMO-TER-010/10040RZMO-TER-010/31540RZMO-TER-010/315/I40RZMO-TER-030/21040RZMO-TER-030/315/I40意大利ATOS叶片泵,柱塞泵,电磁换向阀,溢流阀等价优,常年备有大量库存，价格Zyou，供货快捷，以下产品备有大量现货,欢迎来电咨询!E-ME-AC-05F/4R-420/3,
