使用过滤调节器的重要性（中英文）

空气过滤器调节器是更简单、廉价的装置，在任何气动系统中都发挥着至关重要的作用。这些单元同时完成两个不同的目的。首先，它们过滤空气供应中的液体和颗粒物。其次，它们为系统中的其他过程或设备提供平稳、可靠的气压。下图显示了 ControlAir 300 型空气过滤减压阀的剖视图。该过滤器（40 微米或 5 微米过滤器）以绿色突出显示，以显示供应空气在调节之前如何被迫通过该过滤器。其结果是下游空气得到良好的调节、清洁。

Air filter regulators are simpler, inexpensive units that play a crucial role in any pneumatic system. These units accomplish two different purposes at the same time. First, they filter liquids and particulate matter from an air supply. Second, they provide smooth, reliable air pressure to some other process or device in the system. The image below shows a cut-away of the ControlAir Type 300 Air Filter Regulator. The filter, either a 40 micron or 5 micron filter, is highlighted in green to show how supply air is forced through this filter prior to being regulated. The result is well regulated, clean air downstream.

这些类型的监管机构的重要性基于两种不同方式的成本节省。更敏感的单元，例如I/P 传感器和阀门定位器，包含小孔螺钉、滑阀和电路板等组件。空气污浊是 IP 传感器故障的常见原因。通过使用过滤调节器，可以保护设备免受损坏，减少设备的维修或更换。

The importance of these types of regulators is based around cost savings in two different ways. More sensitive units, such as I/P Transducers and Valve Positioners, contain components such as small orifice screws, spool valves and circuit boards. Dirty air is the most common reason for failure of an IP transducer. By utilizing a filter regulator, you are protecting more sensitive, and likely more expensive, equipment from damage that could result in a costly repair or need to replace the unit.

节省成本的第二个方面涉及过滤调节器下游发生的任何事情。如果下游装置的输出会根据装置的输入压力而变化，则必须为此类装置提供稳定的空气供应。直接来自压缩机的空气可能会根据空气压缩机的状态而波动。如果供应空气的压力波动正在改变塑料挤出应用中使用的下游单元的输出，则如果工艺空气压力与预期设定值相差太远，最终产品可能无法使用。通过调节和过滤来自压缩机的空气，能够为控制过程压力的装置提供非常稳定的供应压力，因为过滤调节器可以很好地处理供应空气的波动。例如，装置中的供给压力每变化 25 PSI， 过滤器调节器的输出只会变化0.25 PSI。如果发生这样的波动，控制过程压力的单元在提供给该单元的供应压力中只会经历 0.25 PSI 的变化。供应压力的 0.25 PSI 变化不太可能对该装置的输出产生影响。

The second aspect of cost savings involves whatever is happening downstream from the filter regulator. If there is a unit downstream that has an output that will change based on the input pressure into the unit, it is going to be essential to provide stable air supply to such a unit. Air coming directly from a compressor could fluctuate based on the state of the air compressor. If this pressure fluctuation of supply air is changing the output of a downstream unit used in, for example, a plastic extruding application, the end product may not be usable if the process air pressure is too far from the intended set point. By regulating, and filtering, the air coming from a compressor, you are going to be able to provide very stable supply pressure to the unit controlling the process pressure as filter regulators can handle fluctuations in supply air very well. The output of the Air filter regulators will only change by 0.25 PSI for every 25 PSI change in supply pressure into the unit. If a fluctuation like this were to occur, the unit controlling the process pressure would only experience a 0.25 PSI change in the supply pressure being provided to that unit. This 0.25 PSI change in supply pressure is unlikely to have an impact on the output of that unit.

空气过滤调节器是任何气动系统的重要组成部分。它们有助于为下游工艺提供清洁、可靠的空气供应，并充当较昂贵设备的廉价保护者。这两个因素将减少因维修或故障而损失的时间，并提高流程效率。

Air filter regulators are an important part of any pneumatic system. They help to provide clean, reliable air supply to your downstream process and act as an inexpensive defender to your more expensive equipment. These two factors will result in less time lost due to repair or failures and great efficiencies from your process.
