Determination and prediction of the automatic valve service life

Valves are among the vulnerable units in a piston compressor, and they significantly influence the system operation. The currently created design of the automatic valves for a low-speed piston compressor requires an experimental research to confirm the predicted service life of such valves. The paper proposes a method for experimental service life testing and a stand for its implementation. Valves with elastomeric elements were tested for 5,000 hours in modes typical for the low-speed piston compressors Research was carried out to determine physical and mechanical properties of the elastomeric elements. Analysis of the obtained results shows that the parameters remain unchanged for the specified operation time. In the future, it is planned to continue testing and bring the confirmed service life up to 25,000 ... 30,000 hours.
