Turbo Compressor Fault

mquay-compressor vibration anlysis

Vibration analysis indicated that the compressor was surging which would cause damage and probably require a strip-down. However, by identifying precisely what was happening mechanically within the compressor and discussing the results with an AC expert, the fault was diagnosed as a gas shortage causing liquid to flash across the expansion valve – cured by re-charging. This example illustrates the power of non-invasive fault identification.
