IS CLAMP USED IN DUST COLLECTION SYSTEMS?
One of the most vital parameters in dust collection systems is dust transport rates. Powders must be transported within a certain speed range depending on their type and weight. Falling below these speeds at any point in the piping while the system is being designed causes precipitation of dust and clogging in the pipes. Exceeding the dust range causes both excessive energy consumption and abrasion and perforation of the pipes. For this reason, when designing the system, it must be designed according to these transport speeds.
It is a completely wrong practice to try to adjust the speed by placing flaps on all suction points in dust collection systems. Because even opening/closing the damper at a single point will upset the speed balance in the whole system. It will increase the speed at some points, and decrease it at other points. Therefore, with a single valve, the danger of clogging at some points and abrasion at some points is created.
In dust collection systems, the damper is used only on the condition that it is in 100% open or 100% closed position and does not have the slightest effect on the velocity value in the other piping system. For example, if you have two cabinets side by side with the same suction flow rate and you do not operate these cabinets at the same time, but operate them with the logic of either one or the other, you can provide significant savings in the initial investment cost and operating cost by using a damper there.
