SAIP S.R.L.: pulsation Dampeners
Hydraulic systems work under pressure. This creates a buildup of energy which can increase the pressure in the system. To compensate for this, accumulators are used.
The accumulator is fitted into the system and is half-filled with gas. As the pressure in the system changes the gas will be compressed or expanded, depending on the pressure difference. This changes the pressure of the hydraulic system and helps to regulate it between a pre-defined range.
Pulsation dampeners are an integral part of these types of systems. Although the accumulator is very effective at regulating the pressure, it doesn’t prevent fluctuations in pressure, it reacts to them.
The speed of this reaction will depend on the specific accumulator chosen. To prevent damage occurring in your system you need pulsation dampeners.
How The Pulsation Dampeners Work
Anything moving in one direction will keep going until it hits something else. Inside your hydraulic system, this means hitting other components, such as the diaphragm in the accumulator or the part that needs to be moved.
But, once the item has been moved, or a valve has been closed, the fluid will come to an abrupt stop. That creates a harsh pressure against the valve or other component. It’s akin to an egg hitting a pavement.
This harsh pressure pushes against the valve, creating a pressure spike and testing the seals on the valve. The resulting spike can be sent back through the liquid and damage key components in your system. Pulsation dampeners prevent this from happening.
They sit between anywhere the fluid needs to stop and the component stopping it. Pulsation dampeners simply dampener the effect of liquid stopping, making it a gentle process instead of harsh. This prevents the pressure spike and the potential damage to your system.
Choosing The Right Pulsation Dampeners
You should note there are several different types of pulsation dampeners. A membrane dampener works in the same way as the accumulator, preventing the fluid and the component from ever touching. Bladder and bellow pulsation dampeners work along similar lines, while the pressure vessel style uses a vessel to remove the pressure by taking advantage of the small amount of compressibility available in fluids.
