Certification
In 2001 the quality management system of SPC Dynamics was put through facultative certification. In 2016 it was recertified for compliance with standards ISO 9001:2008. Its results confirmed a high level of goods and services quality management. In 2001 the quality management system of SPC Dynamics was put through facultative certification.

Analysis of modern methods and means for piston compressors monitoring and diagnostics. Part 2. Real-time monitoring systems

Print

The article dwells upon the criteria of the equipment condition. The selection of diagnostic methodology and parameters, which not only detects condition but allows to carry out diagnostics with the required operation conditions and maintenance depth. Among the big variety of measured parameters the most informative are acoustic vibrations, which sources are cinematic pair impacts (piston-cylinder, pin-sleeve, etc.)

The sources of vibration acoustic signals of piston machines are given in the article:

  1. Unbalance of the moving and rotating masses – inertial force of reciprocal moving masses, centrifugal force of inertia and the moments of the force.
  2. Gasdynamic processes – pressure force of gases, gas flow during an admission and release.
  3. Impacts and friction between elements and details of assemblies and mechanisms.

The methodology and algorithms of diagnosing of piston machines in real-time monitoring systems are described in the article. Also, the article gives the examples of a proper response of vibroacoustic signals’ various parameters to the condition changes of various piston compressor assemblies.
