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.
This part of ISO 10816 applies to reciprocating compressors
mounted on rigid foundations with typical rotational speed ratings
greater than 120 r/min and up to and including 1 800 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 International Standards and classification for the
intended duty. Drivers are not included in this part of ISO 10816
but guidance values for acceptable overall vibration values can be
found in ISO 10816‑3.
It is recognized that the evaluation criteria might only have
limited application when considering the effects of internal
machine components, e.g. problems associated with valves, pistons,
and piston rings might be unlikely to be detected in the
measurements. Identification of such problems can require
investigative diagnostic techniques which are 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, and
— dry running and lubricated reciprocating compressors.
This part of ISO 10816 does not apply to hyper compressors.
The guidelines are not intended for condition monitoring
purposes. Noise is also outside the scope of this part of ISO
10816.
