Typical Industrial Applications for Chemiquip Porous Metal Pressure Snubbers
Industrial and Military Applications
Chemiquip Snubbers protect pressure gauges on test station for HAWK Missiles, Raytheon Co., Andover, Mass produced for the U.S. Army.
Dampening Pulsations:
Systems which establish pulsations--such as reciprocating machines or force pumps--require protection for the pressure-sensitive instruments assembled to them. The snubber is designed to afford a mean average pressure-response with a maximum of accuracy.
Dampening Surges
If the pressure-sensitive instrument is unprotected in systems where high pressure may be suddenly vented, the mechanism will be damaged or the pointer broken, bent, or shifted up scale. These snubbers are calibrated to give an equilibrium reading either up or down scale in about 2-3 seconds.
For Filtering Small Quantities of Liquids or Gases
The porous membrame in the snubber provides a surface upon which droplets of oil or moisture suspended in a gaseous phase may coalesce. Hence it is possible to remove small quantities of such liquids. When the snubber is used as a filter, particles 1/2 the pore diameter, or smaller, are effectively removed. Information concerning pore size and permeability can be supplied on request.
For Metering
Many types of instruments and machines require that a certain amount of liquid or gas be constantly bled. Here the pressure snubber replaces capillary tubing which is much more cumbersome, harder to control and shows a greater tendency toward plugging. Throughput rates may be supplied in an indefinite variety.
For Mercury - Type Instruments
The snubber dampens pulsations and surges and also confines mercury in the tube. mercury will not penetrate the Grade HX snubber at pressures under 25 psi. Finer grades of snubbers will confine the mercury at higher pressures.
