Description / Abstract:
This part of ISO 10816 establishes procedures and guidelines for
the measurement and classification of mechanical vibration of
reciprocating compressor systems. The vibration values are defined
primarily to classify the vibration of the compressor system and to
avoid fatigue problems with parts in the reciprocating compressor
system, i.e. foundation, compressor, dampers, piping and auxiliary
equipment mounted on the compressor system. The guidelines are not
intended for condition monitoring purposes.
This part of ISO 10816 applies to reciprocating compressors
mounted rigidly with typical speed ratings greater than 120 r/min
and up to and including 1800 r/min. The general evaluation criteria
which are presented relate to operational measurements. The
criteria are also used to ensure that machine vibration does not
adversely affect the equipment directly mounted on the machine,
e.g. pulsation dampers and the pipe system.
The machinery driving the reciprocating compressor, however, is
evaluated in accordance with the appropriate part of ISO 10816 or
other relevant standards and classification for the intended
duty.
It is recognized that the evaluation criteria may only have
limited application when considering the effects of internal
machine components, e.g. problems associated with valves, pistons,
piston rings may be unlikely to be detected in the measurements.
Identification of such problems may require investigative
diagnostic techniques which are outside the scope of this part of
ISO 10816.
Noise is also outside the scope of this part of ISO 10816.
Examples of reciprocating compressor systems covered by this
part of ISO 10816 are:
-horizontal, vertical, V-, W- and L-type compressor
systems,
-constant and variable speed compressors,
-compressors driven by electric motors, gas and diesel
engines, steam turbines, with or without a gearbox, flexible or
rigid coupling,
-dry running and lubricated reciprocating compressors.
This part of ISO 10816 does not apply to hyper compressors.
