Does a natural gas reciprocating compressor experience an increase in current when the compression ratio decreases?
Thread Content
As the title suggests, what is the reason for this? Will I show the image tomorrow??? Is there anyone among the seniors who can explain this? Could it be that the intake pressure is too high, resulting in too much air being drawn in?
When the pressure ratio decreases and the flow rate increases, the current will still rise
Indeed, there is such a phenomenon as you mentioned; it’s mainly due to the lack of time for compression, which results in a lower compression ratio!
There’s no time to compress it. How should I understand this, sir?
As the inlet pressure increases, the density rises as well, the flow rate increases, and the current goes up. However, as the continuous import pressure increases while the export pressure (back pressure) remains unchanged, the compression ratio continues to decrease, and the current will drop. There will be a peak in between
Check if there is any change in temperature; it’s possible that there is cross-feeding of gas into the cylinders, which is causing changes in power output
