What is a pressure gauge snubber, and what are the different types of Snubbers:
When applied to mechanical systems, the pressure gauge snubber principle suppresses excess force or rapid motion "snub." A pressure gauge snubber is used to suppress "snub" excess force or rapid movement in mechanical systems. Pressure snubbers are designed to dampen the effect of pressure pulses and spikes to assure longer service life and readability of pressure gauges in harsh applications. Pressure snubbers protect pressure gauges from the harmful effects of vibrations generated in a pressurized system with pulsations such as positive displacement pumps or compressors.
The porous disc type is on the low-cost end of the snubber spectrum. The porous disc design allows consistent pressure at low speeds so that the gauge's readings are not affected by the filtering material. A piston snubber has a little more advanced design that is often self-cleaning. When pressure increases too rapidly, the piston is forced against the orifice leading to the gauge, stemming the flow for milliseconds. This type of snubber can usually be "tuned" to meet a process's needs by using easily changed pistons of varying sizes. The diameter of the piston and its clearance within the snubber determine the rate of "dampening."
An adjustable Snubber takes that fine-tuning to another level. Many use a combination of a ball check to block surges and a choke valve to smooth out the flow of material into the gauge. The ball check acts a lot like the piston-type snubber in that it is a passive element until a rapid change in pressure pushes it into action. Many adjustable snubbers also benefit from leak-tight shutoff, allowing the operator to remove the gauge for repair or removal.
