Analysis of Stress Waves and Peakvue
January 30, 2007 | No comments » | Read more »
ABSTRACT
PeakVue analysis is actually a measure of "stress wave" activity in a metallic component. Such stress waves are associated with impact, friction, fatigue cracking, lubrication, etc., that generate faults in various components such as rolling element bearings and gears. For example, when a rolling element impacts a defect on a bearing raceway, it will generate a series of stress waves that propagate away from the location of the defect in numerous directions. The wave propagation introduces a ripple on the machine surface that will introduce a response output in a sensor detecting absolute motion such as an accelerometer or a strain gage.

ABSTRACT
Petrochemical Plant operates two NASH vacuum pumps at PTA Plant. These pumps are critical equipment, as when the pump is out of service all process related to PTA should be stopped. One of pumps (NASH Vacuum FJ-10) was getting high vibration level at pump side. In order to find out root cause of high vibration level, PT. Tiara is invited to conduct vibration analysis

Motor Bearing Failure on Lube Oil Pump due to Soft Foot Problem

ABSTRACT
There are two lube oil pumps at Ammonia Plant, one is driven by turbine and another is by electric motor. Turbine driven lube oil pump is the main unit, motor driven lube oil pump is stand by unit. The motor driven unit is only running when the turbine driven unit out of service. Plant Maintenance person reported that frequent bearing failure occurred on motor. Motor vibration on both bearing was very directional at horizontal direction. It was found that frequent bearing failure is caused by soft foot problem.

The motor driven unit is only running when the turbine driven unit out of service. Tiara Engineer was requested to assess condition of lube oil pump (motor driven).

We at Tiara like to spread our thinking to other people, in the past we did thid through mailing list, personal consultation and other. Rightnow, we think that we can approach the audiences more wide trough our corporate blog. a place that we hope will make a little change in reliability world around Indonesia, and the world also.
enjoy, and happy blogging.
