transport speed in variable capacity systems

transport speed in variable capacity systems

transport speed in variable capacity systems

Hi i would like to know your suggestions for maintaining the transport speed in a ventilation system to work at different capacities of airflow according to the stage of the process, at full capacity i get some duct diameters, however in one of the stages of the process is only required to capture a percentage of the corresponding total capacity to some of the branches (the rest of the system would be isolated by valves operated electrically) in this case the transport speed is reduced as it passes through the ducts above designed to transport the total flow. I hope and can help me.

RE: transport speed in variable capacity systems

You can use supplemental air vents to add flow to the main trunk when branches are shut down, such as when certain machines are shut off. These can either be spring loaded dampers, or "either or" shuttle valves wired in with the shut off valves. As you may already know it is vital to keep the main trunk velocity up to prevent product drop out, and ensure that the ducts stay self cleaning.

You are judged not by what you know, but by what you can do.

Thanks for the tip Berkshire
