PALL滤芯的压溃值为两个不同的压差值:
以***2941***定义的压差-A点:压差曲线陡升,接近垂直。表示过滤性能下降;
物理压溃压差-B点:组成滤芯的内部件损坏(如骨架压溃);
正确的滤芯支撑结构***了过滤器的化的压溃值。通常在过滤器壳体上安装旁通阀防止产生***压溃(A点),旁通阀开启压力小于滤芯的***压溃值。旁通阀用于保护过滤器和系统,以免压差过大以及或因此而造成的滤芯压溃。
过滤器的压差随着滤材截留污染物的增多而上升,在旁通阀打开之前,压差指示器发出信号,指明应更换滤芯。
PALL滤芯更换滤芯说明
过滤器的压差随着滤材截留污染物的增多而上升,在旁通阀打开之前,压差指示器发出信号,指明应更换滤芯。
