Description of suction and blowing relationship of side channel blower for blowing and suction
Under normal circumstances, the high-pressure fan has the function of blowing and suction, that is to say, it has an air inlet and an air outlet. Generally speaking, the pressure of the fan refers to the kinetic energy of the unit volume gas flowing through the fan outlet section. Accordingly, the suction force of the fan refers to the kinetic energy of the unit volume gas flowing through the air inlet section of the fan.
The strong suction of side channel blower for both blowing and suction is related to the high air velocity at the suction outlet. The higher the flow rate of the suction outlet is, the greater the perceived suction is; on the contrary, the lower the velocity of the suction outlet, the lower the perceived suction; In the selection of high-pressure fan, if the suction at the suction outlet is large, not only the pressure but also the air volume should be considered, because the suction comes from the flow rate. If the size of the pipe and suction outlet is unchanged, the suction will change twice, that is, the flow rate will change twice, that is, the air volume will change twice; At the same time, with the increase of flow rate and air volume, the pressure will also increase, and the increase of square times, the suction will be doubled, and the pressure will be four times.
