过滤元件过滤性能的单次通过和多次通过试验比较

过滤精度是指过滤元件对不同尺寸颗粒污染物的滤除能力。单次通过和多次通过试验是评定过滤元件重要参数——过滤精度的主要方法。过滤元件过滤精度的表示方法及评定结果在过滤与分离行业中有很多形式 ,由于试验标准及方法的各异 ,性能评定结果有很大差异。某些过滤元件尽管其标注的过滤精度值相同 ,但其实际过滤效率相差很大。真正了解过滤元件性能评定表示方法 ,是选择过滤元件可靠性的关键。

Contrast Between Single-pass Test and Multi-Pass Test for Filtration Performance of Filter Parts

Single pass test and multi pass test are the major methods of evaluating the key characteristic filtration precision,Which refers to the capacity of a filter part to remove different sized particle contaminants,Zn filtration & Separation industry there are various forms of precision indication and result evaluation,and different test standards and methods may lead to considerably different evaluated results.Some filter parts,though having same normal ratings,do rot conform with their actual filtration efficiency.therefor it is crucial for selecting reliable filter parts to deeply comprehend the indication and evaluation methods.
