Rexroth力士乐缓冲阀A10VSO71DFR/31R-PPA12KB3油泵



一是加剧密封圈与轴套间的磨损，过早泄漏；二是增大了动环轴向调整、移动的阻力，在工况变化频繁时无法适时进行调整；三是弹簧过度疲惫易损坏；四是使动环密封圈变形，影响密封效果。静环密封圈越紧越好。静环密封圈基本处于静止状态，相对较紧密封效果会好些，但过紧也是有害的。一是引起静环密封因过度变形，影响密封效果；二是静环材质以石墨居多，一般较脆，过度受力极易引起碎裂；三是安装、拆卸困难，极易损坏静环。叶轮锁母越紧越好。
不必再安装截止阀：在检修某一环路时，可将该环路上的动态平衡阀关闭，此时动态平衡阀起到截止阀截断水流的作用，检修完毕后再回复到原来锁定的位置。因此安装了动态平衡阀，就不必再安装截止阀。系统增设(或取消)环路时应重新调试整定：在管网系统中增设(或取消)环路时，除应增加(或关闭)相应的动态平衡阀之外，原则上所有新设的动态平衡阀及原有系统环路中的动态平衡阀均应重新调试整定(原环路中支管动态平衡阀不必重新调整)。
LSZ系列多普勒超声波流量计是一种耐用的、非接触式测量的超声波流量计，它可以在管道外部测量液体的流量，无需对管道进行破损和改造。安装和拆卸十分方便，为您省去了一笔可观的安装和拆卸费用，并且可使您的工艺不间断，这样也就将因仪表安装儿造成停产的损失减到了低。LSZ多普勒超声波流量计采用先进的单片机技术和超大规模集成电路，使其高度智能化，极大的提高了运行的稳定性，从而保证了仪表的精度和可靠性。仪表的外壳采用进口全塑机箱，达到IP65的防护等级。
ZDF系列多功能电磁阀则可通通于气.液体。好订时告明介质状态，安装用户就不必再调式。电磁阀1.2介质温度不同规格产品，否则线圈会烧掉，密封件老化，严重影响寿命命。质粘度，通常在5cSt以下。若超过此值，通径大于15mm用ZDF系列多功能电磁阀作特殊订货。通径小于15mm订高粘度电磁阀。质清洁度不高时都应在电磁阀前配装反冲过滤阀，压力低时尚可选用直动膜片式电磁阀作CDP。质若是定向流通，且不允许倒流ZDFN和ZQDFN单需用双向流通，请作特殊要求提出。6介质温度应选在电磁阀允许范围之内。管道参数2.1根据介质流向要求及管道连接方式选择阀门通口及型号。，用于一条管道向两条管道切换的，小通径的选CA5和Z3F，中等或大通径请选ZDFZ1/2。又如控制两条管道汇流的，请选ZDFZ2/1等。2根据流量和阀门Kv值选定公称通径，也可选同管道内径。请注电磁阀意有的厂家未标有Kv值，往往阀孔尺寸小于接口管径，切不可贪图价低而误事。作压差低工作压差在.4Mpa以上是可选用间接先导式;低工作压差接近或小于零的必须选用直动式或分步直接式。环境条件3.1环境的高和低温度应选在允许范围之内，如有超差需作特殊订货提出。2环境中相对湿度高及有水滴雨淋等场合，应选防水电磁阀3.3环境中经常有振动，颠簸和冲击等场合应选特殊品种，船用电磁阀。有腐蚀性或性环境中的使用应优先根据安全性要求选用耐发蚀3.5环境空间若受限制，请选用多功能电磁阀，因其省去了旁路及三只手动阀且便于在线维修。电源条件4.1根据供电电源种类，分别选用交流和直流电磁阀。
