The standard applies to the stationary piston compressors for Т2-Т6 explosive gas groups according to the classification [1] as well as for the stationary piston compressors using the harmful gases, 1–2 class of hazard according to GOST 12.1.007. Also, the standard sets guidance on the assessment of their vibration state during operation and acceptance tests after mounting and repair.
The standard does not apply to refrigerating and oxygen compressors, to the compressors that used to handle the radioactive gases and gases of an acetylene series as well as to the gas-engine compressors.
In accordance with the standard recommendations, the assessment of the equipment vibration state is based on the joint measurements of the displacement, velocity and acceleration of the unit casing as well as compressor mechanism or the compressor case in the direction of the vibration vector maximum.
The vibration measurements in the range from 2 to 3000 Hz are used for an assessment of the vibration state. For the in-depth study to find out the fault condition or the diagnostics, the carrying out of the vibration measurement in the range up to 10000 Hz and higher is recommended.
The standard's requirements may be used in conjunction with recommendation for assessments of vibration state of the general-purpose stationary piston compressors (see, for example, [2], [3]), including the assessment of the monitored vibration parameter value changes criteria.
The standard was developed by the Scientific and DYNAMICS Scientific & Production Center (DYNAMICS SPC), Non-Profit Organization "Research Centre on the monitoring and diagnostics of the technical system" (NPO "RDC CD").
