General principles of filter selections

1, import and export size In principle, the import and export of the filter size should not be less than the import of matching pump size, generally consistent with imported pipe diameter.
2, nominal pressure According to the possible highest filter line pressure to determine the filter pressure rating.
3, the number of hole mesh Main consideration to intercept the impurities particle size, on the basis of medium process technological requirements.All kinds of wire mesh can intercept the particle size of the check table below "mesh specifications".
4, choice of filter material filter material in general and of piping material is the same, that is connected to different service condition can consider to choose cast iron, carbon steel, low alloy steel or stainless steel filter.
5, water filter, filter resistance loss in general calculation under the rated flow rate, pressure loss of 0.52 ~ 1.2 kpa.
