Rotating Machinery Fault Simulation

2018-1-17The prediction of bearing failure is useful information to the production manager but the root cause of the failure is the key information that can prevent a recurrence The point of this discussion is that very few root cause failure modes originate at the factory the majority of failures are worked into bearings once they get into our hands

Diagnose bearing failures beyond root cause analysis Plantengineering Diagnose bearing failures beyond root cause analysis False brinelling of the metal surfaces is caused when the roller and ring are in contact with each other and subjected to vibration over time resulting in the wearing away of the metal The root cause of

High frequency data collection

As others have pointed out you will find these machines at least with respect to gearing failures (as root cause) very reliable In my experience with this type of machine integrally geared compressor as so-called by API most of the issues will be related to rotor related frequencies unbalance bearing

Refrigeration Compressor Failure: Cause Cure

2010-12-15All can cause a lack of lubrication The results of a lack of oil are overheating because of excess friction and finally a "seized-up" compressor The internal parts of the compressor will show uniformly worn and scored bearing surfaces Contamination Contamination was found to be the major cause of replacement compressor failure

Pump Troubleshooting

2020-8-21As the underlying cause of pump failure often extends beyond the failed item these maintenance methods will effectively reinstall the same old problem This is particularly concerning when we realize that over 80 percent of all pump failures tend to manifest themselves at the mechanical seal or the bearings which then act in a manner similar

How Sensor Performance Enables Condition

2019-5-30How to detect and diagnose imbalance Increases in overall system vibration can point to a potential fault created by an unbalanced system but diagnosis of the root cause of the increased vibration is performed through analysis in the frequency domain Unbalanced systems produce a signal at the rotational rate of the system—typically

How to find the root cause of a problem

Your mind!! I don't think anything in life is really a problem unless you think it is I can answer this based on my own experience When my father passed away on 12th feb 2015 my family shattered I was doing my BTECH in Tamil Nadu while my mothe

Thrust Bearing Failure Prevention Analysis

2020-8-19Crankshaft thrust bearings provide a fore/aft gap-control for axial movement (or endplay) of the crankshaft These thrust bearings are located at a specific main bearing location generally at the center main or rear main depending on engine design A thrust bearing is either integrated with a specific main bearing assembly or independent of the main []

How to Determine Root Cause of Excessive Pump

How to Determine Root Cause of Excessive Pump Vibration Excessive vibration is a good indicator that some damaging phenomenon could be occurring within a pump or the immediate pump system which is why many pump users monitor pump vibration on a regular basis

Failure Analysis: A Road Map
