A PULSATION DAMPNER is an item which is used to dampen pulsation. and is a disperser of transients.

Pulsation is dampned by intercepting pressure pulses, and by preventing their creation. Pulsation prevention dampning is by compresibility of a volume, and interception and dissipation dispersal by a dampner is by the directional allignment with the transient waves and "exploding" them where there is no reflection point close by.

A Pulsation Dampner is used in a piping system, generally adjacent to the source of the flow or pressure disturbance, which is typically a modulating element like a pump or a flow control valve.

A Pulsation Dampner is deployed when the level of flow fluctuation or force variation is unacceptably high for the safety of the pipework.

The safety improvement from the use of a Pulsation Dampner is achieved from a proper selection of the connections orientation, and choice of a suitable volume of dampner.

As a pulsation dampner collects the peak flow, and delivers it back to the system when the rate of mass transfer decreases, this averaging to a smoothness allows choice of pipe size to be reduced. Piping cost reduction often saves more than the Pulsation Dampner would cost. This means that smoothness control ability and safety may be an investment of less than nothing.

PulseGuard use Pulsation Dampner to mean that the device both damps and dampens.

pulsatation dampner Short Definition :
Disperses pulse transients and reduces acceleration head .

 

Definition / Explanation

The phrase Pulsation Dampner is probably derived from PULSE DAMPNER. Pulse being a repeated pressure variation caused by system resistance to flow fluctuations. The addition of "ation" to "pulse" , to create "pulsation" comes from a habit of making a word apparently more important or emphatic by adding a latinate ending; so we get PULSATION DAMPNER.

Therefore PULSATION DAMPNER is just - pulse dampner.

Dampner is from "Dampn". Dampn is probably an attempt to make "DAMP" sound more like a positive action, as in "shall I dampn the fire for you" - meaning would you like me to damp the fire down for you.

So it can be surmised that a Pulsation Dampner is really just an emphasized Pulse Dampr.

The Dampn thing is from "DAMP" . So if the Anglo best practice rule were in play (be as short as possible) , instead of North American - make it sound important -the truest phrase would become a PULSE DAMP in place of PULSATION DAMPNER.

Over the last 40 years there has been an increase in the use of Pulsation dImpnr, dUmpnr, dOmpnr on purchase orders and contracts. Unfortunately unless confirmations and invoices were made to exactly replicate these variants, in stead of using PULSATION DAMPNER on the acknowledgment, it became impossible to get paid. The prevalence of these varieties is growing, which makes it necessary to have a written on line explanation for PULSATION DAMPNER plus derivative .

Pulsation Dampner is related to Pulse Dampner and to Pulse Damper The difference between DAMPER and DAMPENER seems to be that:

1. A Damper removes pressure force, like slowing the velocity in a flue or in ducts, or putting a wet sack on a fire to remove heat energy by evaporation.

2. A Dampener on the other hand, tends to APPEAR to have removed energy , but in fact acts by preventing the creation of the phenomenon in the first place. For Example : A "Pulsation Dampener" will provide a compressible gas interfaced to a liquid pumping system, so that the softness provided stops a pump from being able to generate an excess pressure simply to jerk a long column of liquid into movement.

 

THEREFOR
It seems that DAMPENING is by prevention, and DAMPING is by dissipation. So DAMPNING is in part energy removal and partially prevention of overpressure. Accordingly A PULSATION DAMPNER is both an acceleration head generation preventor and pressure wave dissipator. BUT whether this deductive reasoning is correct or not Pulse Dampner Pulsation Dampner or Pilsotion Dampnr and the like are in growing use without much thought to their meaning

This is one of the glories of American "English" as opposed to "Old European Saxon language" - In the USA anything can mean what ever you want it to mean , if you just use it enough for a relatively specific purpose. This is perhaps why we make a haven for attorneys and are such a litigious society. WE NEED DEFINITION.
