Case Study

The Fraunhofer IPT institute develops and optimizes production processes for the precise manufacture of compressor blades using automatic production machines. The blade wheels are shaped by milling and the investigation with the IrisM™ Camera is used to determine the deflection of the blades in the resonancefrequency. In addition, interdependencies and excitations of the blades were determined.

The analysis of complex mechanical systems is a long-term process in which many parameters of the machine must be collected and compared. Using the advanced IRIS M data analysis system, we can control the spectra, orbits, and timewave signals from many points simultaneously and compare the results to identify the source of the problem.

Test rig stations must also be checked for proper functioning. A 7m inductor frame is not an easy object to measure. Motion Amplification technology allows you to examine the structure of large elements and see how 30mm thick steel blocks deform.

Even if you are an experienced vibration diagnostician, it may be that the vibration signature reveals a seemingly different problem, such as impeller imbalance, shaft misalignment, looseness, etc. than it actually is.

View vibration spectra and then analyze the recording to see in practice how MotionAmplification® technology helps to quickly identify an unusual problem with the machine and its foundation.

The implementation of the Iris M system includes theoretical and practical training. During practical classes we record real cases in industry and it turns out many times that interesting problems are diagnosed.

Customer had a recurring problem with overhauled engines, which were still objected to too high levels of vibration. At the same time, there were no such problems at the test rig. A quick recording during the training allowed to discover the real problem inherent in the foundation. Sometimes, before the system becomes finally implemented for use, we can see first return on investment.

Vibrations that accompany fluid pumping processes in pipeline systems can have a negative impact on the technical condition of the structure, durability of connections, and condition of seals. Very often these are low-frequency vibrations such as material deformations, cracks, loosening, which identification now is possible thanks to the IRIS M system.

In many industries failures occurs in machinery operating at very low speeds. It is difficult to make diagnostic measurements using accelerometers at low speeds, especially below 1 Hz (60 rpm), because of very low vibration signal. MotionAmplification® it the first technology in the World for detailed observation and measurement of the lowest frequencies. Watch example of machine in a tire factory, with speed of about 20 revolutions per minute. See how the Iris M system depicts bearing housings of rubber calender machine at 0,35 Hz.

Installation staff repeatedly detect problems with excessive pipeline vibration. Corrective actions are taken to prevent cracks, especially in hazardous gas installations, threatening people and environment. However without adequate measurement of the effects, these actions are far from expectations. See the high pressure pipeline support, installed in chemical plants, which looks like a rigid structure. In fact it falls into resonance vibrations at 22 Hz and does not work as a suitable support for the pipeline.

Before we started using MotionAmplification®, we could not even imagine how many problems with machines are the results of insufficient foundation.

All you need is a quick shot from IRIS M™ to solve the problem of loose gearbox foundation, which translates into poor cooperation with driven machines and has a negative effect on the clutch.
