前言管井过滤器设计合理与否,是供水管井成败的关健。本文拟对管井过滤器孔隙率的有关问题进行一些粗浅的讨论,提出一些不成熟的看法,供商榷和参考。一、管并过滤器孔隙率的计算所谓过滤器的孔隙率即是指过滤面的孔隙率和支撑骨架的孔隙率。不同结构类型的
Preface The rational design of the tube filter is the key to success or failure of the water supply tube well. This article intends to discuss some issues related to the porosity of the tube well filter, and put forward some immature views for commercial reference and reference. The calculation of the porosity of the tube and filter The so-called porosity of the filter refers to the porosity of the filter surface and the porosity of the support skeleton. Different types of structures
