摘要： A system for filtering hydraulic fluid wherein a high flow rate of uncontaminated fluid is required. A filling facility is provided for initial filling or for the addition of make-up fluid to the system which facility assures that such added fluid must pass through a filtration unit prior to integration with fluid already in the system. A by-pass valve is provided to provide pressure relief in the event that the filtration unit becomes clogged during use. The valve, along with an accompanying coarse filtration unit, are readily manually removable from the system for cleaning or repair.
摘要翻译：一种用于过滤液压流体的系统，其中需要高流量的未污染流体。提供了填充设备用于初始填充或向系统添加补充流体，该设备确保这种添加的流体必须在与已经在系统中的流体集成之前通过过滤单元。提供旁通阀，以在过滤单元在使用过程中堵塞的情况下提供压力释放。阀门以及伴随的粗过滤装置可以方便地从系统中移除以进行清洁或修理。
