Calculating Max discharge pressure of Liq. Ring Compressor

[david6245]

Hello,

Does any one know of any theoretical equation for calculating the max possible discharge pressure or compression ratio of a liquid ring compressor?

Since LRs are positive displacement machines, when does the pressure increase stop?

Any references would be great!

Thanks,

Positive displacements usually take you to when the rod breaks, the top blows off, a seal blows out, you melt down, or ... you run out of power to squeeze it any smaller.

Other than that see what you can here,

Noting that if its a vacuum appliation there are vapor pressure constraints,
