General Principles Of Automatic Filters
Dec 27, 2017


In principle, the import and export diameter of the filter shall not be less than the inlet diameter of the supporting pump, which is generally consistent with the inlet line.

Nominal pressure

Determine the pressure level of the filter according to the maximum pressure of the filter line.

Selection of aperture number

It mainly considers the particle size of impurity to be intercepted, according to the process of dielectric process. All sizes of screen can be intercepted to check the size of "filter screen specification".

Filter material

The material of the filter is usually the same as the material that is connected, and the filter of cast iron, carbon steel, low alloy steel or stainless steel can be considered for different service conditions.

Filter resistance loss calculation

The water filter is used to calculate the pressure loss of 0.52 ~ 1.2kpa under normal calculation
