Seismic Dampers - Types, Working Mechanism, and Component

Type-A dampers are the easiest and fastest type to install and are mostly used in low-pressure part of duct systems (up to 2 w.c.). Type-B Fire Damper: Used when airflow or velocity in the duct is a concern. The stack of blades in the fire damper frame is kept out of the air stream. Compared to an Type-A damper, the total square inche dampers have higher performance, passive dampers are still the most commonly used [5]. While there are many types of passive damper, passive variable dampers have been recently developed. Among the passive variable dampers, those with stroke and displacement/position dependent sensitivity have been studied in several works [15-26]. Fukushima e It is a type of spring in which the supported load remains the same throughout the deflection cycle. 5. Variable Spring.

I am trying to find again a small plastic damper that I was looking at last year, but forgot the exact name for that type and now I am unable to find it again. Quite frustrating. It is pretty much a plastic piston with a small hole at the end, which acts as a linear damper and that is pushed back by a spring Another device of increasing damping coefficient will be to adopt mechanical vibration dampers , or an energy absorbing element being set into the tripod-type pretensioned porcelain guys, which will presumably be quite effective for security against seismic shocks 12 A - You sell many types of dampers. How do I determine which damper to use? If you have one duct per zone, you could do either the mechanical dampers (spring return or power open/power close) or the Flexdamper System. If the ducts are easily accessed, the motorized damper would be the more economical choice. Back to to As its name implies, a twin-tube damper uses two concentric tubes. The inner tube is filled with oil and houses the shaft and piston. Like a monotube damper, shim stacks on the piston meter oil..
