To prevent pulsating loads in a piston compressor, what should be installed?

In a piston compressor system, pulsating loads are often caused by the intermittent nature of the compression cycle, leading to pressure fluctuations during operation. To mitigate these pulsations and ensure a more stable output, an accumulator on the discharge side is utilized.

The accumulator serves as a pressure reservoir, storing excess compressed air and releasing it during periods of low demand. This helps to smooth out the flow of air and reduce the amplitude of pressure fluctuations, thereby contributing to a more consistent and steady operational performance. By acting as a buffer between the compressor and the system it feeds, the accumulator effectively dampens the impact of pulsations on connected equipment, minimizing wear and tear as well as potential operational disruptions.

While a pressure regulator may help control downstream pressure, it does not directly address the issue of pulsation. A pulsation dampener is specifically designed for this purpose; however, it operates under different principles and may not store energy like an accumulator. A secondary compressor may provide additional capacity or redundancy but does not directly tackle the problem of pulsating loads caused by a primary compressor's cycling. Therefore, the installation of an accumulator on the discharge side is crucial for managing pulsation in piston compressor systems.
