Webinar Description:

Fluid drives form part of most critical and balance of plant assets in modern-day plants due to its wide applications in numerous material handling as well as high torque conveyor processes. The expensive nature of fluid drive couplings and consequential downtime due to failure necessitates the need for a robust vibration analysis expertise. This webinar will be unveiling the benefits of fluid drive basics, internal configuration, and the basic vibration analysis expertise required for detecting some common faults associated with the components. Live scenarios vibration data and case studies will be utilized in demonstrating the requisite knowledge required for diagnosing fluid coupling failures.

Learning Takeaways

1. Understand real-life operation and components of a fluid drive as it affects an analysts accurate diagnosis
2. An understanding of common machinery faults associated with fluid drives systems and how they could be detected by vibration analysis
3. The relevance of adequate frequency resolution and speed detection in the diagnosis of real-life cases associated with fluid drive systems

We come across similar problems regularly in the equipment having fluid couplings.
In case of conveyor systems, we are able to identify the source of unbalance (turbine side or pump side) using high resolution spectrum. However, during balancing the phase of 1X amplitude keeps changing every second. What do you suggest in order to get the location of balance correction mass if phase in changing to a vast extent rapidly?

Hi Kumar,
Unfortunately you have very little control over the phase change.The change in phase is as a result of the beat taking place between the interacting 1x from turbine and pump.
Proceed with the balance job within a fairly stable phase to trim to a best possible level.You may manually control and accept the data if using CSI 2140 data collector.

Having encountered various problems related to unbalance of conveyor drives, I can totally relate to the case studies shown.
But the major issue we find during the balancing of the system is that phase angle of 1X vibration keep on changing vastly and rapidly.
High resolution spectrum does help to identify which side is having greater unbalance (turbine or pump). But what do you suggest if we aren’t able to determine the phase angle?

Hi Kumar,
do not use the angular division method, rather use discrete if your data collector support that.In that case your focus is on the radial locations or positions.
The phase should not be perfectly stable you know due to beating phenomenon.
