Peculiarities of operating modes of booster piston compressors based on a low-speed long-stroke compressor stage in mobile compressor stations

Abstract

The article considers the relationship between the increase in temperature at the standard suction point of a booster long-stroke low-speed piston compressor stage and the change in the state parameters in the working cavity of the cylinder and its integral characteristics. The parametric analysis is performed using a proven and verified mathematical model of the actual working processes of the stage in question. Based on the results of the conducted calculation and theoretical analysis, the fundamental possibility of implementing operating modes in which the average discharge temperature of a given stage is lower than the temperature at its standard suction point is proven. At the same time, with regard to the suction conditions in a given stage, there is an increase in the delivery coefficient. The presented results reflect the features of the operating processes of the piston compressor stage under consideration and allow predicting the possibility of its effective use as a booster stage in mobile compressor stations.
