关系式分析引荐罗斯蒙特3051t型压变的导压管堵塞问题。

    罗斯蒙特3051系列变送器有很多种,今天我们就罗斯蒙特3051t型压力变送器关系式分析来简单了解下导压管堵塞问题。 

    设罗斯蒙特3051t型变送器增加后的流量为f2,(即:f2> f1), p2= p2+- p2- ,f’2=k ,f’2为流量增加后的罗斯蒙特3051t变送器输出值。  

    设原流量为f1, p1= p1+- p1- ,f’1=k , 

     则: f’现=k = k  

      则: p2= p2+- p2- = p1+-( p1-+ p0- p0?)= p1+( p0?-p0) 

     p2- = p1-+ p0- p0? 

    当流量增加时,p2-泛起如下变化:由于实际流量增加为f2,则与原流量f1时比拟,罗斯蒙特3051t的管道内的静压力也相应增加,设增加值为p0,同时p2- 因管道中流体流速的增加而产生的静压减小,减小值为p0?,此时p2-与p1- 的关系为:

     因为罗斯蒙特3051t的正压管堵塞,则当实际流量分别为f1、f2时,p1+= p2+; 

    故f’1为变化前罗斯蒙特3051t变送器的输出值。 

    以上关系式进行分析,就可以更有利于了解罗斯蒙特3051t型压力变送器导压管堵塞问题。
