Compressor issues

What causes loud noises in a reciprocating compressor circuit?
It’s that the sound in the loop is extremely high-pitched; in our factory, all loops return to one section
1. The circuit has been widened； 2. The loop diameter is too small.
Could you please be more specific? I’m a beginner. Thank you
It was already clearly explained on the 4th floor: the pressure difference is too large, and the linear velocity is too high.
Sound is generated by the frictional vibration of gas against pipes, and reducing the flow velocity can effectively lower noise levels.
The pressure difference is too high, and the linear velocity is too high.
Simply put, the flow velocity of the fluid in the pipeline increases. The reason for this increase could be a sudden reduction in the diameter of the pipeline; with a constant amount of gas, a smaller pipeline diameter inevitably leads to an increased flow velocity. In life, it’s like when water flows out of a pipe: under normal conditions the water sprays up to 5 meters, but if part of the outlet is blocked, the spraying distance increases – it’s the same principle. Is that clear enough?
