Manufacturer of Pulsation dampeners are devices used to smooth out pressure fluctuations or pulsations in fluid systems, especially in systems where pumps (like positive displacement pumps) cause rhythmic pulses. These dampeners reduce vibration, noise, and potential damage to system components while helping maintain a stable flow rate. Here’s how they work:
1. Absorption of Pulses Using a Flexible Barrier
Structure: Pulsation dampeners typically consist of a chamber divided by a flexible diaphragm, bladder, or bellows. One side contains the process fluid, while the other side holds a gas (usually air or nitrogen).
Operation: When the pump creates a pressure pulse, the fluid pushes against the diaphragm or bladder, compressing the gas. This gas absorbs some of the pulse energy, dampening the fluctuations.
2. Energy Absorption Through Gas Compression
Gas, being compressible, can absorb and release energy as it is compressed and expanded. This absorption smooths out the fluid pulses because the gas cushion flexes in response to each pulse, absorbing its peak pressure and slowly releasing it.
3. Steady Flow Creation
As the dampener absorbs pressure spikes, the fluid flow becomes more uniform. By minimizing fluctuations, it stabilizes the system’s overall pressure and flow rate, enhancing performance and reducing wear on components.
4. Varieties of Pulsation Dampeners
Hydraulic Accumulators: Used in hydraulic systems, often in a bladder type, to absorb fluid shocks.
Inline Dampeners: Installed directly in the fluid line, designed to match the system’s pressure and volume requirements.
Pump-Mounted Dampeners: Connected directly to pump outlets to reduce pump-specific pulsations.
Applications of Pulsation Dampeners
Industrial Pipelines: For steady flow in chemical, water, or oil pipelines.
Fuel Systems: Prevent cavitation and protect components in fuel injection systems.
Hydraulic Systems: Stabilize the pressure in hydraulic circuits to improve machine operation.
In summary, pulsation dampeners operate by using a gas-filled chamber with a flexible barrier to absorb and release pressure fluctuations, creating smoother and more controlled fluid flow. Visit https://www.amerigoexports.com/dampner.html
