Hydraulic filter is an indispensable device on the transmission medium pipeline, usually installed in the pressure reducing valve, pressure relief valve, fixed level valve or other equipment at the inlet end, used to eliminate impurities in the medium to protect the normal use of valves and equipment.

There are hundreds of hydraulic filter products, so how to choose? Asahi Hydraulic - professional manufacturer of hydraulic filter to teach you to choose the right hydraulic filter should be considered from the following points:

1, import and export diameter: in principle, the import and export diameter of the filter should not be less than the matching pump inlet diameter, generally consistent with the inlet pipe diameter.

2. Nominal pressure: Determine the pressure level of the filter according to the highest pressure that may appear in the filter pipeline.

3, the selection of the number of holes: mainly consider the size of the impurities to be intercepted, according to the process requirements of the medium process. The particle size of various specifications can be intercepted by the screen check the table "filter specifications".

4, filter material: the material of the filter is generally the same as the material of the connected process pipeline, and the cast iron, carbon steel, low alloy steel or stainless steel filters can be considered for different service conditions.

5, filter resistance loss calculation: water filter, in the general calculation of rated flow rate, pressure loss is 0.52 ~ 1.2kpa.
