One customer provides conditions
         The weight of the adsorbent grinding wheel is 100kg, the suction ring has a ring design, the outer diameter is 1200 inner diameter 230, and the perforation hole diameter is 40 at the adsorption area. The length of the pipe cannot exceed 5M.
    
    Determination of two suction cups
        1, determine the number of punches
           Total area = 3.14 × 6002CM2
                     Hole area = 3.14 × 202CM2
                     Maximum number of punched holes = total area / hole area = (3.14 × 6002) / (3.14 × 202) = 900
           Considering the processing cost and the cost performance of the fan selection, it is determined to be 100
           Adsorption effective area = 200 × 3.14 × 0.022 = 0.25 M2

Third, determine the fan pressure and flow
 
      P=F/S=4×100×/0.125=
Considering the pressure loss and resistance, multiply by the safety factor of 5. The fan selection pressure is 400 mbar
