Behavior of dry-running piston rod sealing systems in crosshead compressors

摘要

Great demands are placed on the reliability of dry-running i process gas compressors,due to the extraordinarily high ' costs resulting from any production losses.A simultaneous increase in die requirement for higher load parameters-particularly in terms of the pressure difference to be sealed and the average piston velocity-and longer maintenance intervals has led to more frequent dimensioning of dry-running sealing systems at the limits of stable operation.
