Calculation of total pressure under abnormal operating conditions of fans
Thread Content
Fan nameplate parameters: flow rate 180,000, total pressure 14,500, power 1,120, speed 1,480, operating temperature 60°, direct start mode. Process flow: coal grinder - pipeline - dust collector - pipeline - fan - chimney. If the coal mill gets clogged and the fan creates a vacuum, what can be the maximum total pressure? How to calculate it?
Just ask the manufacturer to provide the performance curve for checking; simply doing the calculations is complicated, and it’s not easy to do on-site!
