Investigation of Pulsation Dampers for Personal Respirable Dust Samplers.
NTIS: PB 203 656 :13 pages
The Bureau of Mines studied a pulsation damping device designed to smooth pulsating flow in personal respirable dust samplers. The effect on the pulsation dampener efficiency of six parameters was investigated, as follows: volume, diaphragm elasticity, diaphragm area, center orifice area, inlet-outlet-orifice area, and geometry (l/d ratio). The results indicate that volume predominates in determining snubber efficiency, while the other parameters become important at small volumes. Geometry has no effect on snubber efficiency. Criteria for an efficient pulsation dampener construction were obtained.
