Solyanyk V. The improvement of vibrodiagnjstic methods and means of controlling gas compressor units GPA -25/76

The dissertation is devoted to the solution of vibrocontrol and vibrodiagnostic problems of gas compressor units (GCU) of great single power. The problems of determining vibrocontrol systems specifications of threeshaft GCU GPA -25/76 are solved. The dynamic features of GCU GPA -25/76 defining vibro activity of the main assemblies are investigated. Experimental investigations of the units ' vibration characteristics are conducted.. The dependence be-tween vibration parameters and the technical state of GCU GPA -25/76 assemblies are determined. Worked out are functional diagrams on the basis of which apparatus and program means of vibrocontrol and diagnostic systems are created. Methods and ways of accomplishing units vibrocontrol and diag-nostics under conditions of compressor stations are developed. A number of vibrodiagnostic indications of GCU GPA-25/76 are determined. The main results of the work are introduced at gas pipeline 5compressor stations.
