Pulsation and Vibration Analysis: Pipes shaking, feet buzzing, gauges breaking, small bore piping failiures?

Pulsation - Vibration Analysis and troubleshooting evaluates current vibration levels to identify components that exceed industry accepted vibration guidelines.  Vibration levels on compressors, engines, pumps , motors and entire compressor skids are tested at specific conditions and speeds to pinpoint vibration problems.  Changes in operating pressures, loading conditions and speed can have a drastic affect on vibration levels. Specific vibration analysis techniques are required to identify vibration that may be due to mechanical forces or pulsations. Further testing on components Mechanical Natural Frequencies (MNF) can be identified through simple bump testing or more accurately, forced response testing.  Identifying the Mechanical Natural Frequency of the component helps to determine whether you are adding stiffness to the system with supports and bracing or if adding mass would be the better control strategy.

Reciprocating Vibration analysis and control takes experience and knowledge of working compression systems to accurately determine the root of the problem.  We apply our field experience to make practical observations and solutions trying to keep the realities of installing vibration or pulsation control in mind. Changes to existing bracing or adding additional braces are simple steps that are typically taken at the field level to make quick changes to bring the vibration into safe levels. Some changes would require more engineering to existing pulsation controls with either the addition of orifice plates at stratigic locations or the total remanufacture of bottles. Pulsation testing is performed at specific locations and levels are compared to API 618 guidelines.   Previous analysis groups suggested pulsation control for a chronic vibration problem.  Vibration levels were near 2x industry guideline on multiple test points on the unit and many attempts to add bracing to the scrubbers were made by field staff. Detailed analysis by EMS Inc. formulated this repair that reduced vibration levels that "have been that way for 20 years!"  EMS Inc. knows the difference and how to find the solutions!

Industry Networking EMS Inc. has a close working relationship with one of the industries leading providers of  Compressor Mechanical - Acoustical Design and Elite Pulsation Vibration Analysis, Peerless Dynamics LLC .  This allows us to provide a broader range of expertise to our clients when the need for Compressor Mechanical - Acoustical Design and modelling.  Also, more intricate vibration analysis such as Operating Deflected Shape (ODS) can be performed and modelled to display unit distortion and motion from the vibration data aquired.
