1, Import and export of diameter: In principle, the import and export of filter diameter should not be less than the matching pump inlet diameter, in general, consistent with the inlet pipe diameter.
2, Nominal pressure: According to the filter pipe may occur to determine the maximum pressure of the pressure level of the filter.
3, The choice of hole number: the main consideration to be blocked impurity size, according to process requirements of the media process. A variety of wire mesh size can be intercepted check the following table “filter specifications.”
4, The filter material: the filter material is generally selected and connected to the same process pipe material, for different service conditions can be considered to choose cast iron, carbon steel, low alloy steel or stainless steel filter.
5, The filter resistance loss calculation Water filter, in the general calculation of the rated flow rate, the pressure loss of 0.52 ~ 1.2kpa
