Monitoring of Rolling Element Bearings (Part 2)

2020-11-10T09:44:59+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)

2020-11-10T09:58:59+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.

Condition Monitoring on a reciprocating compressor in a shale oil plant

2020-11-10T07:47:40+01:00Customer Case Studies, Cases with PROGNOST®-NT, Online Condition Monitoring, Published Articles, Reciprocating Machinery|

Reciprocating compressors are often used to handle very dirty and corrosive gases that have a negative impact on component lifetime and affect on the plant productivity. Due to this fact there are several ways to handle this problem, a few plants are using a identic machine as backup and in case of failure they are using the twin machine to keep the process running. But maybe this is not the best way. Efficient plants are asking for a condition monitoring system, this is where PROGNOST Systems comes to the play. A installation of a condition monitoring system like PROGNOST®-NT brings several benefits to the operator. Starting at the maintenance planning because he sees the development of his wearing parts and [...]

Company (LDPE industry) avoided costs, by trusting Machine Monitoring System

Detection of various valve failures on LDPE hyper compressor within the six weeks of operation saved 250 million USD in production loss

Orbit plots for successful monitoring of rotating machinery

2020-11-10T08:05:51+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

2020-06-05T09:41:18+02:00Intelligent 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

2020-06-05T09:39:19+02:00Intelligent 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.
