Information
To calculate the filtration area, simply put, there is a formula:
S=L/K
S——Filter area (m2)
L——rate of flow (m³/min)
K——Velocity of flow (m³/m2*min);This coefficient is related to the efficiency, pressure drop, and life of the filter material.
In our selection, we mainly rely on experimental data.therefore,filter selection recommendations or let the manufacturer to choose.
Yinbeier is the production, research and development of imported, domestic mechanical equipment filter element and filter assembly; Hydraulic system high, medium and low pressure filter element; Air compressor oil and gas, oil and water; Oil filter element; Air purification; Drying filter; Water purification; Dust filter core and other products based enterprises.
There are three major curves for filtering:
Differential pressure flow curves (Δ P - Q),
Particle size and filtration ratio curve (mu-beta),
Time and pressure drop curve (T - Δ P)
Therefore, the calculation of the filter area is based on these three curves, the most important of which is the flow differential pressure curve.
Filtration area calculation steps:
1. Determine the filtration ratio with a filtration accuracy of 25μm, such as 200 (filtration efficiency), determine the appropriate filter material;
2. Perform a flow differential pressure test on the filter material according to a given pressure drop of 0.05 MPa. Get the right flow (L/min);
3. Calculate the flow rate (L/min.m2) based on the resulting flow divided by the area of the test media;
4. Determine the filtration area according to the flow rate and the actual applied flow rate, rate of flow / velocity of flow = filtration area;
5. Determine the filter structure according to the selected filter area and filter material, folding filter or cylindrical winding filter.
