WOODWARD 5439-986 涡轮电子调速器

启动燃料限制设置启动序列期间的最大执行器位置,当速度达到控制设定点时，它会偏置,此功能可用于限制过多的启动烟雾，减少过多燃油的冲洗作用造成的气缸磨损，并有助于缩短启动时间。

Starting Fuel Limit sets the maximum actuator position during the starting sequence, which is biased when the speed reaches the control set point. This feature can be used to limit excessive starting fumes, reduce cylinder wear caused by the flushing action of excess fuel, and help shorten start-up times.

如果需要，可提供外部开关连接来禁用启动燃料限制，以防止反向作用系统在磁性拾取器丢失时恢复到启动燃料位置，该控制装置可最大限度地防止电磁和射频干扰。

If desired, an external switch connection can be provided to disable the start fuel restriction to prevent the reverse acting system from reverting to the start fuel position in the event of loss of the magnetic pickup, and the control provides maximum protection against electromagnetic and radio frequency interference.

Woodward USA设计并制造了Woodward 505控制系统，这是一种用于单执行器或双执行器汽轮机的基于微处理器的控制器。
