蒙那多频闪仪测量时如何对风扇进行标记？

如图所示，在 3 个风扇叶片上放置一块 T-5 反光胶带。 风扇的速度为 1500 RPM，通过 Pocket-Tach转速表验证，将一 (1) 条胶带贴在中心轮毂上。将蒙那多Nova Strobe 频闪仪频率调整为运行速度的 3 倍。 3 x 1500 = 4500 转。 当您将蒙那多频闪仪速度提高三倍至 4500 RPM 时，叶片将相互叠加，从正面看时，风扇会显示“Hi”。 在滑轮、轴、联轴器和多叶风扇上试试这个演示。

蒙那多频闪仪作为诊断检查灯

当风扇运行时，用频闪仪从侧面照射。 您将能够检测到刀片相对于彼此的任何“摆动”或错位。 状况良好的风扇应该将三个叶片叠加在一起，看起来像一个叶片。

您可以使用 美国蒙那多频闪仪（monarch instrument nova strobe portable stroboscopes）检查弯曲的滑轮、柔性板刀片、松动的螺栓、缺少油脂、裂缝和打滑的皮带。

HOW TO MAKE A FAN TALK 

Place a piece of T-5 reflective tape on the 3 fans blades as shown. The speed of the Fan is 1500 RPM as verified with a Pocket-Tach aimed a one (1) piece of tape applied to the Center Hub. Adjust the Nova Strobe Flash rate to 3 time the running speed. 3 x 1500 = 4500 RPM. When you triple the speed to 4500 RPM all the blades will be superimposed on each other and the Fan will read “Hi” when viewed from the front. Try this demo on pulleys , shafts, couplings and multi-bladed fans.

Nova Strobe as a Diagnostic Inspection Light 

As the fan is running view it from the side. You will be able to detect any “wobble” or misalignment of the blades relative to one another. A fan in good condition should have all three blades superimposed appearing as a single blade. 

You can use a Nova Strobe to inspect for bent pulleys, flexplate blades, loose bolts, lack of grease, cracks and slipping belts.
