CASE STUDY : Extruder motor, hydraulic pump defect detected
Reporting on fault detection and identification of anomalies through comparative analysis of similar equipment.
Extruder Motor
Larger acceleration RMS observed in Extruder No. 4 compared to Extruder No. 3.
RMS (ROOT MEAN SQUARE)
A measure of the average magnitude of vibration.
Larger acceleration RMS observed in Extruder No. 4 compared to Extruder No. 3.
Hydraulic Pump
A harmonic phenomenon is observed where multiples of the rotational component (20Hz) occur together.
COLOR MAP
The X-axis represents the period, the Y-axis represents frequency, and the magnitude of vibration is distinguished by color.
It is difficult to distinguish whether the harmonic is due to equipment characteristics or a defect, but monitoring is necessary.
⚠️ Defect found in the filter connected to the pump equipment.
