Basics of Pulsation Vessels

Definition and Function:

Pulsation vessels, also referred to as pulsation bottles, are specially designed containers integrated into industrial fluid systems to mitigate pressure fluctuations. Their primary function is to absorb and dampen pulsations, surges, and vibrations generated by dynamic equipment such as pumps, compressors, or reciprocating engines. By acting as a buffer, pulsation vessels help maintain a more constant flow and pressure within the system, ensuring smoother operation and reducing stress on downstream components.

Components and Construction:

Pulsation vessels typically consist of a cylindrical or spherical shell made from materials capable of withstanding high pressures and corrosive environments commonly found in industrial applications. The vessel may include additional components such as inlet and outlet connections, pressure relief valves, gauges, and mounting brackets.

Working Principle:

The working principle of pulsation vessels revolves around the concept of volume elasticity and compressibility. When fluid flow experiences sudden changes in velocity or direction, it creates pressure fluctuations within the system. Pulsation vessels exploit the elasticity of trapped air or other compressible mediums inside the vessel to absorb these pressure variations. As the fluid pressure increases, the compressible medium compresses, storing potential energy. Conversely, when pressure decreases, the compressed medium expands, releasing stored energy to maintain system pressure within acceptable limits. This cyclical process helps dampen pulsations and fluctuations, promoting smoother fluid flow and reducing the risk of damage to system components.
