本标准规定了单向气流通过粮堆的单位压力损失的测定方法,它可以用来计算通风机组的总压损。即相当于以下几处压力损失之和:
a)在通风系统中(通风管道等);
b)在粮食中(本标准的主要内容);c)从管道进入粮堆的通道处。
本标准适用于气流速度在以下范围的通风系统中压力损失的测定。如果气流速度不超过以下限速,通风系统中的压力损失和气流从通风管道进入粮堆的通道中的压力损失,相对于粮堆中的压力损失而言,,可以忽略不计:
———主通风管道中的速度8m/s~10m/s;
———分通风管道中的速度4m/s~5m/s;
———进入粮堆的速度0.25m/s。
本标准不适用于气流速度不大于以上限速的通风系统(如主管道中气流速度达到30m/s),该情况下要计算由于气流分配以及卸料系统所引起的压力损失。
