The deviation of the flow rate of the anticorrosive fan is the deviation of the conveying gas, which leads to the uneconomical use. What is the reason for the occurrence of the anti-corrosion fan? How to solve?
1. The actual value of pipe network resistance is too different from the calculated value. If the actual value of the characteristic coefficient k of the pipe network is less than the calculated value, the flow will increase, and if the actual value of k is greater than the calculated value, the flow will decrease.
2. When the total pressure deviation δ p is not taken into account, the flow rate increases when the actual total pressure is positive deviation, and the flow rate decreases when the actual total pressure is negative deviation.
1, replace the anticorrosive fan with higher or lower pressure.
2, use throttle device to adjust the flow rate. As by adjusting the air valve or door.
3, change the speed of the anti-corrosion fan impeller.
4, change the resistance of the pipe network to adjust the flow rate.
Through the above knowledge, we can see that anti-corrosion fans generally use throttling devices to regulate the flow and reduce the frequency of deviation.www.jnblower.com
