Already at the end of the ’68 it was discovered that poorly lubricated and/or damaged bearings emitted mechanical waves inside the materials.
Therefore, being able to detect and measure these mechanical waves was the easiest and fastest way to diagnose the condition of the bearings. The mechanics already knew this: with a screwdriver or an iron rod resting on the ear and bearing seat, they could give their opinion.
Whether you call them “structure-borne” Ultrasound or Shock Pulse, we are talking about the same thing: acoustic waves in materials working at frequencies >30kHz.
SPM Instrument was born from the name given to these pulses: Shock Pulse Measurement.
It allows a quick, easy and non-invasive check of the bearings directly in the field, for condition maintenance activities and verification of malfunctions.
When a machine vibrates, it deflects light in an imperceptibly variable way over time, depending on its frequency and type of movement.
A small system capable of analysing vibrations and shock pulses in detail, intervening with automatic alarms when the thresholds set for each symptom are exceeded.
Whether it is a bearing damage, a misalignment, an unbalance, a tower gear, the system is able to understand the cause of the anomaly and the increase in vibration or shock pulse values detected and to send a signal to the PLC or to the supervision system.
The Intellinova Parallel MB system applies the advanced SPM HD and HD ENV algorithms, designed to work on simple machines, even in stand-alone applications, providing the best of itself when coupled to DuoTech® sensors.
The Leonova “Diamond Aligner” is the simple and lightweight tool ideal for field alignments on horizontal and vertical machines.
Very light, compact, with bluetooth laser heads, it can align shafts up to 3 metres long.
There is of course the routine to analyse and correct the presence of “lame foot” in order to obtain the optimal conditions before performing the typical specific operations for good alignment.
The instrumentation also makes it possible to carry out thermal compensation, to take into account machinery with large temperature variations during operation.
It is very important to remember that even the best joint coupling is not able to reduce bearing loads when alignment is not carried out in the correct way: only precision alignment guarantees maximum life of the rotating parts.
Fixed acquisition system for vibration analysis and Shock Pulse up to 32 channels for each unit, with the possibility of interfacing multiple units for the realization of complex systems.
It can also acquire analogue signals indicated by the customer.
