About the Company

An Indian multinational company operating in several segments such as lubricants, refinery, gas, and LPG. In refinery, offer a full range of automotive engine oils, gear oils, specialty oils and greases.

Challenge

The large refinery of India wants to transform its manufacturing line into smart manufacturing as its operations require complex machinery and sophisticated processes. During the production, they faced erratic failure of pumps which resulted into lower productivity. Thus, the company wanted to implement an IoT solution that helps in minimizing equipment fouling.

Solution

  • IDE detected quite irregular FFT spectrum for the Z axis for Pump.
  • Anomalous harmonics in the 2x, 3x and 4x regions (first two even and first odd harmonics) indicating the onset of misalignment or looseness.
  • No large peak in the frequency spectrum for the dominant frequency indicating a clear misalignment or eccentricity in the system in the Z axis about the X-Y plane.

Result

  • Fixing the pump assembly on-site resolved the issue completely.
  • The pump failure resulted in varying temperature profiles in which a continuous repeatable pattern was observed.
  • Average temperature was around 50 degrees but high standard deviation indicated loading and unloading pattern or varying load patterns.
  • Sharp peak / increase in temperature on 28 August which was tagged as anomalous by the system as correlated with the vibration spectrum of the pump at the same time.

Transformation

With the help of FFT spectrum the company can now analyze the faults in motor, pumps, gears and better provide against negative machine health conditions such as imbalance, misalignment and looseness.
