SYSTEM FOR INFLATION PARAMETERS MEASUREMENT OF PNEUMATIC SEAL UNDER POSITIVE AND NEGATIVE PRESSURE GRADIENT ACROSS THE INFLATED SEAL

摘要

A system 100 for measuring inflation parameters, including, but not limited to, a proper inflation pressure, inflation gap, contact area with the sealing surface� for a pneumatic seal under positive and negative pressure gradient, and evaluating the performance of the pneumatic seal under varying stages of the inflated height and pressure gradient is described. In the proposed system, the pneumatic seal is mounted on a bottom plate 104, and an upper plate 102 height is variably adjusted. There is a valve 108 for supplying compressed air to inflate the pneumatic seal, and measure and evaluate the inflation patterns and the sealing efficiency under the specified pressure gradient. The pressure gradient is created from the upper plate valve 112 by supplying compressed air when the seal is fully inflated, and also the vacuum is applied to create negative pressure gradient. Here, the inflation parameters can be determined for any pressure gradient and inflation gap.
