A sudden amplification Cyl 4 & 1 when the machine running at 550 RPM and Vibrations ~ 0.8 ips pk and vibrations down to ~ 0.6 ips pk with rpm at 450 rpm.
The vibration spectrum review shows a amplification at 4X vibration when the machine running at 550 RPM due to cylinder resonance.
Cyl 1&4 vibrations is amplified when running at 550 RPM
Cyl 1 & 4 vibrations drops to lower levels at 550 rpm
Real-Time Monitoring of assets by shoreline AI
The customer checked and confirmed the resonance when the machine is running at 550 RPM and planned to increase the stiffness .
Once the customer took corrective action to by adding a stiffener at discharge bottle support, this significantly lowered the vibration level when the machine running at 550 RPM & maximum load
Shown here is an alarm raised by the ShorelineAI APM/PdM platform.
Spectrum on the left shows amplified energy levels at 4x on cylinder 1 when the machine is running at 550 RPM.
Once the discharge volume bottles support stiffener were implemented and issues were resolved and the cylinder 1 vibration returned to normal at 550 RPM.
Spectrum on the right shows reduced energy levels at 4x on cylinder 1 when the machine is running at 550 RPM. This is a clear indicator of lowered cylinder 1 vibration, thereby improving the useful life.
Spectrum charts below indicate the before and after repairs.
Cyl 1 Energy amplified levels at 4x when the machine running at 550 RPM
Cyl 1 Energy reduced levels at 4x when the machine running at 550 RPM
Timely alarm and quick maintenance action save reciprocating compressor from further damage, thereby preventing a disruption of operations and a costly breakdown.
