Pipe network resistance difference between the actual value and the calculated value is too large. By the general network characteristics of the equation P = KQ2 (K is the drag coefficient) it shows that if the actual value is less than the calculated value K K, desulfurization fan, the flow rate increases; if the actual value is greater than the calculated K K the flow is reduced. Big, sometimes small. Or fan in the area flying work and other reasons; installation requirements: according to the location and size of the installation shown in the drawings, Tyan fan, in order to obtain high efficiency, in particular to ensure that the air inlet and the impeller gap size; to ensure the horizontal position of the spindle, and to measure non-parallelism and concentricity of the coupling end faces of the spindle and the motor shaft. _ Gas stove gas pressure fan blower (certified) _ Tai'an Zibo Blower Factory Co., Ltd. by the fan.
