| Summary: | This article discusses the problem of combating pressure fluctuations in the suction line of piston
compressors. As you know, incorrect calculation of communications can lead to accidents of compressor
equipment. Therefore, special attention must be paid to the layout of pipelines and equipment, while
avoiding resonance phenomena. One way to combat pressure pulsations in the suction line is to install
diaphragms. This method is the cheapest and easiest to implement, especially for compressors already
in operation.
The experimental studies carried out confirmed the known data that the area of the diaphragm opening
should be four times smaller than the diameter of the pipeline. At the same time, a threefold reduction
in the amplitude of pressure fluctuations is achieved. Installation of a diaphragm design with parameters
close to the recommended ones is possible anywhere in the suction line, since the change in amplitude
at different pressure from the suction valves does not exceed 5...7 %. When installing a diaphragm with
dimensions different from those recommended, it is necessary to install it closer to the suction valve. |
