A deviation in cylinder 2 temperature when compared with other five cylinders.
The vibration spectrum indicates increased in energy content at high-frequencies between gas pulsation region 4 – 8 Khz and the time waveform shows noisy / leaky valve openings instead of crisp valve openings.
Real-Time Monitoring of assets by shoreline AI
Shown here is an alarm raised by the Shoreline AI APM/PdM platform.
The customer checked and confirmed that the discharge valve found leaky. Once the customer took corrective action to replace the discharge valve, cylinder temperature back to normal
Cylinder 2 started deviating from its regular temperature pattern and rose to 126 °F Cylinders 6 and 4 are maintaining a maximum temperature between 105 – 115 °F.
After valve replacement temperature back to normal trend 105 – 115 °F.
The spectrum and time waveform on the left show high amplitude and noise in the gas pulsation region. The time waveform also indicates noisy or leaky valve openings
As per the recommendation, customer replaced the discharge valve.
The spectrum and time waveform on the right show reduced amplitude and noise in the gas pulsation region. The time waveform indicates crisp valve opening
Spectrum charts below indicate the before and after repairs.
4 Khz to 8 Khz Spectrum shows increased energy/noise, from the lazier valve opening
Post valve replacement 4 Khz to 8 Khz Spectrum shows reduced energy/noise.
Instead of crisp valve opening events, noisy valve type signal pattern
Post valve replacement crisp valve opening events in twf signal pattern
Timely alarm and quick maintenance action saves the reciprocating compressor from further damage, thereby preventing a disruptive, expensive plant shutdown.
Shoreline AI’s plug-and-play asset performance management delivers breakthrough simplicity and cost efficiencies. Completely self-installed by non-experts, smart sensors automatically connect to the cloud and are auto-provisioned via a rich library of 30,000+ pre-built asset physics models.
