Rationing of piston machines vibration

Existing documents in the field of piston machines vibration rationing, in particular standards VDI 2056, ISO 2372, ISO 10816-6, the draft standard ISO 10816-8, as well as commercial standards, do not provide diagnostics and a safe, fault free compressors operation. Moreover, the draft standard ISO 10816-8 is not intended to be used in monitoring systems, since it does not guarantee the compressors safe operation as well. In 2011 in Russia the industry standard STO 03-007-11 has been adopted; it allows to carry out a vibration analysis monitoring of the piston compressors crucial components and ensures the compressors safe operation.

The standard applies to stationary piston compressors, operating on explosive and hazardous gases and sets the vibration standards for assessing their condition during operation and acceptance tests after mounting and repair.

The vibration parameters rates, specified in STO 03-007-11, are of advisory nature for all the machines which are not enumerated in the machinery list, supplied in the standard appendix.

These rates ​​can be adjusted according to resolutions of the enterprise responsible technical services as bringing the diagnosed equipment to the required reliability activities, guaranteeing safety and fault-free operation of the hazardous facilities. The standard specifies the vibration parameters rates and prescribes their use for the arrangement of vibration monitoring, vibration analysis, condition monitoring and operational risks for stationary piston compressor units.

This document determines the frequencies ranges of measurement for each vibration parameter and proposes to measure not only the mean square values ​​of acceleration, velocity, displacement, but their amplitudes, as well. The vibration rates are given for the five compressors constructive groups with unit capacities from 0,02 to 2 MW. The paper considers the standard STO 03-007-11 main issues.
