removing the contaminants of the hydraulic fluid Contaminants mainly occur in the form of metallic abrasions laquer rubbed off seal parts dust and scale These dirt particles are transported to all points of a hydraulic system Constantly increasing performance of hydraulic systems and devices results in high requirements with respect to the switching accuracy of valves This has been achieved among others by reducing the fit tolerances between housing and control piston Contaminants can thus cause immediate failures if the slide of a valve jams due to the presence of dirt particles 反向冲洗过滤器用作主 全流量压力过滤器 在液压系统中 它能够截留 过滤和除去液压液体中的污染物 污染物主要包括金属磨损物 漆 磨损的密封组件 灰尘以及水垢 这些杂质颗粒会被传输到液压系统中的各 个角落 为了持续改善液压系统和设备的性能 需要保证阀门具有较高的开关精确度 通过减少阀壳和控制活 塞之间的配合公差来达到这种效果 在这种情况下 如果因为设备中存在杂质颗粒而使阀门斜面堵塞 那么这 些污染物很快就会导致设备故障 The Backflush Filter with electrical pilot operation can be connected to a central computer which measures the available pressure using sensors and initiates the backflushing process on the basis of preset parameters either dependend on pressure or on time The contaminated filtrate is generally drained via separate lines 带有电先导阀操作功能的反向冲洗过滤器可以与电子控制器 ASG 5 相连 控制器通过传感器测量可用的压力 并根据预先设定 的压力或时间参数来启动反向冲洗过程 带有污染物的滤出液通常会通过分离的管路排出 功能说明功能说明 The Backflush Filter consists of the filter housing and filter elements Contaminated pressure fluid enters the filter housing through the housing inlet PIn It flows through the two filter elements from the inside out Dirt particles which are smaller than the pore screen size of the filter element are trapped and retained to prevent them contaminating the hydraulic system further The filtered fluid leaves the housing via outlet POut 反向冲洗过滤器包含过滤器阀壳和过滤器元件 带有污染物的压力液体通过阀壳入口Pin进入过滤器阀壳 它经过两个内部过滤 器元件 然后流出 大于过滤器元件孔 网筛的杂质颗粒会被挡住和截留 这样它们就不会继续污染液压系统 经过滤的液体通 过出口Pout离开阀壳 The degree of contamination of the filter element can be evaluated by observing the pressure MPin and MPout between the filter inlet PIn and the filter outlet POut the socalled differential pressure An increase in contamination of the filter element causes the differential pressure to rise If the pressure difference exceeds a preset value the filter element has to be backflushed This backflushing process removes dirt particles from the filter element 可以通过观察过滤器入口 Pin 和过滤器出口 Pout 的压力 分别为 MPin 和 MPout 之差 称为压差 来估计过滤器元件的污染程 度 如果过滤器元件的污染程度加重 会增加压差 如果压差超过了一个预先设定的数值 就必须对过滤器元件进行反向冲洗 以便把杂质颗粒从过滤器元件中除去 The contaminated pressure fluid also flows through the housing leaving it at the opposite end If the filter is used as single filter the rear of the housing will be closed It is possible to connect several filters to conduct parallel filtration 带有污染物的压力流体还会流经阀壳 并从相反的一侧流出 如果把过滤器用作单过滤器 阀壳的后侧会被关闭 此外 还可以 同时连接若干个过滤器 实现并行过滤 反向冲洗反向冲洗 Backflushing is initiated by operating the pilot valve located the head of the filter Normally the electric pilot valve controlled by the head gate computer will initiate the backflush process In the manual variant the pilot valve V5 V6 is operated manually The pilot valve is supplied with the backflushed hydraulic fluid internally 通过操作位于过滤器头部的先导阀来启动反向冲洗 在通常情况下 由 Head gate 计算机控 制的电先导阀会启动反向冲洗过程 在 手工 变量中 先导阀 V5 V6 通过手工方式操作 先导阀的液压流体在内部进行反向冲洗处理 83 205254 00 0e doc 第 3 页 共 7 页 状态 2005 年 11 月 22 日 修订版本 3 0 Backflush Filter 反向冲洗过滤器反向冲洗过滤器 Drawing No 83 205254 00 0 Item No see below 图纸号 83 205254 00 0 项目号 参见下文 Activating the pilot valve starts the backflushing process Operating one function of the V5 V6 pilot valve flushes the corresponding filter element Internal valves V1 2 2 way valve DN32 and V3 3 2 way valve capsule DN15 or V2 2 2 way valve DN32 and V4 3 2 way valve capsule DN15 are reversed and the pressure fluid flows through the filter element in the opposite direction for about 2 to 3 seconds so that dirt particles can be loosened and the contaminated fluid is drained via the leakage port 启动先导阀开始反向冲洗过程 V5 V6 先导阀的一个功能就是冲洗相应的过滤器元件 内 部阀门 V1 二位二通 DN32 和 V3 二位三通阀门组件 DN15 或 V2 二位二通阀门 DN32 和 V4 二位三通阀门组件 DN15 是反向的 压力液体流经反向的过滤器元件大 约 2 到 3 秒钟 以便除去杂质颗粒 带污染物的液体通过泄漏端口排出 While one side of the filter i e one filter element is backflushed the other side continues filtrating to permit troublefree operation to the possible extent The two sides should be flushed one after the other and never at the same time Shut off valves are not allowed to be installed in the flushing outlets as backflushing is made with high pressure 当过滤器的一侧 也就是一个过滤器元件被反向冲洗的时候 另外一侧持续进行过滤 以 便尽可能实现无故障操作 两侧应该轮流过滤 而不能同时过滤 因为反向冲洗是在高压 下进行的 所以在冲洗出口不能安装截止阀 While the lifetime of the filter depends on the degree of contamination of the fluid to be filtered it is not possible to make any binding statements as to when and how often backflushing should be conducted A general recommendation would be to backflush the filter elements once every shift 因为过滤器的寿命取决于要过滤器的液体的污染程度 所以不可能给出明确的反向冲洗操作的时间和频率 建议每班次反向冲洗 一次过滤器元件 更换先导阀控制电路过滤器元件更换先导阀控制电路过滤器元件 The pressure fluid of the 4 3 way pilot valve is cleaned via a separate plug type filter which should be cleaned regularly 三位四通先导阀的压力流体通过分离的插拔型过滤器来清洁 应该定期清洗这个过滤器 It is vital to depressurize the backflush filter before commencing work If the backflush filter is connected to other filters all filters must be depressurized The pressure indicator reading if available should be checked 在开始操作之前一定要对反向冲 洗过滤器进行降压 如果反向冲洗过滤器与其它过滤器相连 所有过滤器都必须降压 在操作中应该尽可能检查压力指示器的读 数 Remove the staple lock by using pliers or a screw driver Next pull the plug type filter out of the bore Please note that residual fluid may flow out Please rinse the filter thougly and refit the filter into the housing Refit the staple lock and pressurize the backflush filter again 通过钳子或者改锥卸下卡钉锁 接下来把插拔型过滤器从钻孔中拔出 请注意残留的液体可能会流出 请彻底冲洗过滤器 并把 过滤器重新安装到阀壳上 然后重新安装好卡钉锁 并再次对反向冲洗过滤器进行降压操作 更换主电路过滤器元件更换主电路过滤器元件 The filter cartridges should be replaced as and if required It is vital to depressurize the backflush filter before commencing work If the backflush filter is connected to other filters all filters must be depressurized The pressure indicator reading if available should be checked 在必要的情况下 应该更换过滤器的插装阀芯 在开始操作之前一定要对反向冲洗过滤器进行降压 如果反向冲洗过滤器与其它过滤器相连 所有过滤器都必须降压 在操作中 应该尽可能检查压力指示器的读数 To replace the element loosen and remove the screw connection at the bottom of the filter pipes by using an open end wrench sized SW55 Please note that residual fluid may flow out Using the built in ring of the filter itself the filter element can now be pulled out of the filter pipe by means of the ring fitted 在更换元件之前 要通过一个 SW55 尺寸的开口扳手拧松并卸下过滤器管末端的螺丝部件 请注意残留的液体可能会流出 使用 过滤器自带的内置环将过滤器元件从过滤器管中拉出 Next install the new filter element into the filter pipe Check the o ring of the screw connection for any damage replace if required and grease it lightly Install the screw fitting and tighten pressuretight by means of the open end wrench sized SW55 接下来 把新的过滤器安装到过滤器管道中 检查螺丝部件的O形圈是否有任何损坏 在必要的情况下更换 然后轻轻涂抹油 脂 用一个SW55尺寸的开口扳手安装固定螺丝 并用力拧紧 83 205254 00 0e doc 第 4 页 共 7 页 状态 2005 年 11 月 22 日 修订版本 3 0 Backflush Filter 反向冲洗过滤器反向冲洗过滤器 Drawing No 83 205254 00 0 Item No see

in order to obtain an extended parallel connection 反向冲洗过滤器在内部通过并行方式连接 这样一来液体就可以流经每个过滤器元件 也可以把若干个过滤器接起来 以便增加 并行连接的长度 To this end the individual filters are connected to this end by the special nested
