Abstract:

The article considers the temperature conditions of combined multi-stage compressor units based on screw oil-filled and piston low-speed long-stroke compressors as part of air and nitrogen mobile compressor stations. Based on the results of the calculation and theoretical studies, the relationship between the design of low-flow medium- and high-pressure booster piston compressors based on long-stroke low-speed stages with their temperature conditions and the thermal load on heat exchangers has been established. It has been shown that at a fixed operating mode of a low-pressure screw oil-filled compressor, the use of booster piston compressors based on a low-speed long-stroke stage allows reducing the thermal load on heat exchangers and ensuring a safe temperature regime during operation in a wide range of atmospheric temperatures. The results obtained allow us to predict improvements in the specific overall dimensions and weight characteristics of mobile compressor stations.
