COMPARATIVE ANALYSIS OF EFFECT OF GAS COMMUNICATIONS STRUCTURE OF GAS-MOTOR COMPRESSORS ON PULSATIONS AMPLITUDE
The article analyses effect of gas communication structure on pulsations amplitude originating due to periodic work of gas-motor compressors. Gas-motor compressors of МКС12/(75-85)-(85-180) and 10ГКНАМ1/(50-53)-(70-125)/90-(125-150) type appear the object of research. Some method of calculation and diagram build-up of gas supply to buffer tank of gas-motor compressors providing estimation of dynamic processes in gas armature is suggested. The method is based on calculation of a number of gas portions entering the buffer tank in equal interval of time. The build-up diagrams served the basis for performing analysis of gas movement dynamics in buffer tank and gas pipelines. This method is recommended to be used in case of choosing the compressor equipment for concrete pressure modes and productivity. The analysis of effect of buffer tank structure of gas-motor compressors on appearing pulsations amplitude is carried out and the advantage of the design with conic transition which confirmed its dynamic stability in practice is shown.
