Intelligent Machine Monitoring

“Intelligent Machine Monitoring” is a video production from experts for experts. Viewers learn basics of signal analyses as well as advanced topics to improve the results of their daily work. Enjoy the movies and feel free to share your thoughts in the comments section. We are also open for your suggestions for topics to be explained and discussed.

How to detect liquid carryover in reciprocating machinery

2021-01-07T15:14:21+01:00Intelligent Machine Monitoring|

In this video we will learn more about liquids passing through reciprocating machines what can be a very dangerous problem on those machines. Christian will show us more about early failure detection to avoid the liquid slug which will result in huge damage. He explains the relation between gas flow and vibrations in connection with liquids inside the compression chamber. Watch now on our YouTube Channel.

Monitoring of Rolling Element Bearings (Part 2)

2021-01-07T15:30:20+01:00Intelligent Machine Monitoring|

This second part is about the challenges in the analysis of rolling element bearings. Oliver is going deep into the analysis to find the root cause of the failure. He starts with sensor placements, also addresses environmental challenges, and finally comes to the signal which is generated by the sensor. The signal is transferred into the FFT Spectrum where it is analyzed by the support of the fault frequencies.

Monitoring of Rolling Element Bearings (Part 1)

2021-01-07T15:36:31+01:00Intelligent Machine Monitoring|

Tutorial for understanding the important basics of rolling element bearing monitoring. Learn what BPFO, BPFI, 2BS and FTF mean and how to detect impending bearing failures. The basis are time waveform readings from acceleration sensors that need to be transformed into FFT spectra with the specific frequency components.

Orbit plots for successful monitoring of rotating machinery

2021-01-07T15:36:36+01:00Intelligent Machine Monitoring|

Monitoring the displacement of shafts in rotating machinery is mandatory to detect impending failures at an early stage. This tutorial describes how to generate Orbit plots and how to read them. This introduction of the orbit analysis will answer the following questions: How to read an Orbit plot?For what reason a Orbit plot can be used?How the Orbit plot is generated?What problems can be detected by using the Orbit plot?

How to identify failures with pV diagram analyses

2021-01-07T15:38:18+01:00Intelligent Machine Monitoring|

During the video we will talk about the discharge and the suction phase of the pV diagram. What are the most typical differences to see in the signalDelay of the valve opening How to influence and how to react We will learn much about the compression cycle, different typical pV diagram characteristics, and common shapes.

Displacement sensor and wear monitoring on reciprocating compressors

2021-01-07T15:38:42+01:00Intelligent Machine Monitoring|

As shown in previous movies there are different probes to monitor the compressor behavior. In the video we would like to talk about the proximity probe to monitor the vertical piston rod displacement. This probe is installed close to the packing and could be installed above or below the piston. Additionally a second probe per piston could be installed to monitor also the horizontal displacement. During the video we will talk about functionality and different analyses for this sensor signal.
