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.

The Piston Compressor: The Methodology of the Real-Time Condition Monitoring

Print

The methodology of a diagnostic signal processing, a function chart of the monitoring system are considered in the article. The methodology of monitoring and diagnostics is based on measurement of indirect processes' parameters (vibroacoustic oscillations) therefore, no more than five sensors is established on the cylinder, measurement of direct structural and thermodynamic parameters is described as well.

The structure and principle of expert system's functioning of decision-making is given. Algorithm of automatic expert system includes the calculation diagnostic attributes values based on their normative values, formation sets of diagnostic attributes that correspond to individual classes to malfunction, issuing of expert system messages.

The scheme of a real-time condition monitoring system for piston compressors is presented in the article. The system has consistently-parallel structure of information-measuring equipment, which allows to measure the vibroacoustic signal for condition monitoring of reciprocating compressors and their operation modes. Besides, the system allows to measure parameters of other physical processes, for example, pressure in decreasing spaces (the indicator diagram) for monitoring and diagnostics, the inlet pressure and flowing pressure of each cylinder, inlet and delivery temperature of gas, valves temperature, position of a rod, leakage through compression packing and others.
