摘要
目前测量锅炉炉顶吊杆载荷的方法主要有应变片法、弦振式应变计法和刻痕法3种。针对这几种方法的缺陷和局限性,提出了通过测量吊杆的固有频率变化来测量载荷的方法,即动测法。通过试验表明,该方法结构简单、测量精度高、使用方便。
Directing against defects in three methods used at present for measuring the load of hanger rod at furnace roof of boiler, a method of measuring the said load by using measurement of natural frequency variation for hanger rod, namely mobile measuring method, has been put forward. Results of test show that the mobile measuring method has simple structure, and high measurement accuracy,and being convinient to use.
