FLOWGUARD PULSATION DAMPENER, also known as a FLOWGUARD PULSATION DAMPER, is a device used in fluid systems to reduce or eliminate pulsations or fluctuations in pressure and flow. Here's how it generally works:
Cyclic Flow: In fluid systems like pumps, compressors, or hydraulic systems, the flow of fluid often creates pulsations or surges due to the cyclic nature of their operation. These pulsations can lead to pressure variations downstream.
Accumulation of Fluid: A pulsation dampener typically consists of a chamber filled with gas (such as nitrogen) separated from the fluid by a flexible membrane or bladder. As fluid under pressure enters the dampener, it compresses the gas inside, storing energy.
Smooths Pressure Fluctuations: When the fluid pressure drops, the stored gas expands, pushing the fluid back into the system. This action helps to smooth out the pulsations in the fluid flow, reducing pressure fluctuations downstream.
Frequency Damping: The design of the dampener is such that it effectively dampens the frequency of the pressure pulses generated by the pump or compressor. This is achieved by adjusting the volume of gas and the compliance (flexibility) of the membrane or bladder.
Applications: Pulsation dampeners are used in various industries where stable fluid flow is critical, such as in oil and gas pipelines, water treatment plants, chemical processing, and even in certain medical equipment.
In essence, a pulsation dampener acts as a buffer or shock absorber within a fluid system, absorbing the cyclic energy fluctuations and releasing it in a smoother, more controlled manner. This helps to protect downstream equipment, ensure consistent process performance, and reduce noise and vibration associated with fluid pulsations.
