Vibration Analysis & Shock Pulse Monitoring overview:
Vibration analysis & shock pulse monitoring consists in listening inside the machine. Each component vibrates differently and generates a characteristic noise that leaves a typical fingerprint in the spectrum in the form of a linear pattern. If the damage is present, the pattern stands out from the noise floor. This allows the specialist to recognize, for example, whether the problem comes from unbalance, misalignment or bearing damage. In addition to an accurate diagnosis, it is also possible to determine whether an urgent action is necessary or it can be done the next scheduled servicing.
Shock pulse analysis
When a bearing has a lubrication problem or an incipient failure, it starts to emit ultrasound.
Historically, the structure-borne ultrasound generated inside bearings and gearboxes have been called “shock pulses,” and the technology able to detect this type of signal has now reached an incredible level of reliability.
Using the new SPM Shock HD detection technique, even bearing rotating below 1 RPM (yes, ONE round per minute) can be analyzed for faults and malfunctioning.
The exclusive sensor and analysis algorithms, together with the incredible technical capability of the new SPM Instrument equipment, will allow capturing even the smallest defect in the inspected machines.
This will improve the reliability management and the plant performances dramatically.
Vibration & Shock Pulse analysis – The benefits
The bottom line is that vibration analysis benefits both the operator and the maintenance technician:
✔ Enables the identification of machine faults
✔ Provides information on causes
✔ Localizes the affected components
✔ Optimizes spare parts logistics
✔ Allows early planning of maintenance measures
