Gauges Buzzing? Clamps breaking? Small diameter piping issues?
Pulsation – Vibration Analysis and troubleshooting evaluates current vibration levels to identify components that exceed industry accepted vibration guidelines. Vibration levels on compressors, piping, coolers, 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 effect 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 accurate force hammer triggered natural frequency detection and Modal Analysis. 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.
We provide a simplified approach to our analysis, yet use our 40+ years of experience to fully understand the problem and make positive improvements to your machinery. Simple issues such as vibrating grating or broken clamps up to full frame distortion issues have been identified and dealt with. We work hard to ensure our clients receive cost effective and accurate results.
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.

You always hear about failures happening at other sites, are you sure your unit is safe?
Some changes require more engineering to existing pulsation controls with either the addition of orifice plates at strategic locations or the total re-manufacture of bottles. Pulsation testing is performed at specific locations and levels are compared to API 618 guidelines.
Piping failures, broken supports, gauges failing? These are all symptoms of possibly serious Pulsations and resulting Vibrations that could easily become a safety concern. Vibration levels left unchecked can cause catastrophic failures at bottle nozzles, pressure relief valve flanges and the list goes on.
Pulsation and Vibration analysis evaluates and quickly identifies vibration problems that can be a potential safety and reliability concerns. Determining the severity of the vibration problem, the cause, and then being able to provide a solutions is key. Our analysts draw on over 40 years of combined experience in the reciprocating machinery field. This can provide very concise and proven solutions that can get you up and running again quickly.

- Pulsation-Vibration (P-V) analysis can identify potential vibration hot spots and reduce sources of failure. Some solutions can be as simple as clamping placement or as complex as pulsation control. Our industry experience can provide proven solutions and results eliminating trial and error methods of repair.
- A vibration assessment is given for the entire unit as well as associated piping taking into account loading and operational changes.
- Inspection of the unit frame mounting, skid to pile connections and other support structures are closely inspected.
- Rotating Vibration analysis on items such as screw compressors, electric motors, gear boxes, turbo-expanders can be evaluated and documented for typical failure modes.
A simple solution can save you downtime and possible safety risk.
