• Wilkerson过滤器，Wilkerson新产品

  Wilkerson过滤器，Wilkerson新产品Wilkerson威尔克森过滤器由简体、不锈钢滤网、排污部分、传动装置及电气控制部分组成。过滤器工作时，待过滤的水由水口过滤器流Wilkerson威尔克森过滤器经滤网，通过出口进入用户所须的管道进行工艺循环，水中的颗粒杂质被截留在滤网内部。如此不断的循环，被截留下来的颗粒越来越多，过滤速度越来越慢，而进口的污水仍源源不断地进入，滤孔会越来越小，由此在进、出口之间产生压力差，当大度差达到设定值时，差压变送器将电信号传送到控制器，控制系统启动驱动马达通过传动组件带动轴转动，同时排污口打开，由排污口排出，当滤网清洗完毕后，压差降到Z小值，系统返回到初始过滤状，系统正常运行。Wilkerson威尔克森过滤器由壳体、多元滤芯、反冲洗机构、和差压控制器等部分组成。壳体内的横隔板将其内腔分为上、下两腔，上腔内配有多个过滤芯，这样充分利用了过滤空间，显着缩小了过滤器的体积，下腔内安装有反冲洗吸盘。工作时，浊液经入口进入过滤器下腔，又经隔板孔进入滤芯的内腔。大于过滤芯缝隙的杂质被截留，净液穿过缝隙到达上腔，Z后从出口送出。新产品查看新的Wilkerson产品！查看Wilkerson的R90系列。90系列允许在不使用管道连接器的情况下将单元连接在一起。这样可以节省空间，提供恒定的安装ZX，并保持现代的美观外观。新目录和产品列表！R90系列产品目录下载目录607：R90系列FLR产品其他新产品文献：公告9EM-B3：R120调节器公告9EM-B1：D级工业呼吸空气的空气准备目录604：气动产品-精密调节器FRL-SIF-619：精密调节器清洁干燥空气系统的更多信息（PDF）目录：603：烘干机产品：液体分离器，排水阀和制冷干燥机FRL-SIF-618：压缩空气干燥指南FRL-TEC-600：聚碳酸酯碗化学兼容性Wilkerson过滤器，Wilkerson新产品New!90SeriesFRLProductsSafetyLockOutsCombinedSoftStartandRemoteOperatedDumpValveHighPrecisionRegulatorsWSA/WSOSeriesLiquidSeparatorWDV3AutomaticElectricalDrainValveWDV2SeriesZeroLossDrainWDRDSeriesRefrigerationDryerModularBallValveWilkerson过滤器，Wilkerson新产品[详细]
