为了方便地获得锅炉中煤粉的流量,设计了一套新型风速测量装置。利用涡轮流量计的设计原理,阐述了旋转叶轮风速仪的设计依据,并设计了方案。经过风洞实验,选择双支承式旋转叶轮风速仪。在方案确定后,对测量装置进行了总装设计,并具体给出了叶轮及传感器隔热的设计。最后通过实验验证了这种新型风速测量装置能准确地测量流量。 In order to obtain the flow of pulverized coal in the boiler conveniently, a new wind speed measuring device was designed. Using the design principle of turbine flowmeter, the design basis of the rotary impeller anemometer is expounded and the scheme is designed. After wind tunnel experiment, choose double bearing rotary impeller anemometer. After the plan is confirmed, the assembly of the measuring device is designed and the design of the impeller and the sensor insulation is given specifically. Finally, the experiment verified that the new wind speed measuring device can accurately measure the flow rate.
