Vibration Measurement and Analysis

Principles and Concerns

There are some fundamental principles that apply to all rotating machinery. They are:

  • All Machines Vibrate when they run
  • Any increase in Vibration is a sign of trouble
  • Each trouble has its own unique characteristics

These Characteristics are Amplitude, Frequency and Phase. Each Characteristic has its own significance:
  • Amplitude - Indicates Severity of Vibration
  • Frequency - Indicates most likely cause of Vibration
  • Phase - Helps Identify exact cause of Vibration

While Understanding Vibration Amplitude is pretty simple and Straight Forward; Understanding Vibration Frequency and Vibration Phase is not so. Many a times, it is found that people own the right tools to measure vibration amplitude, frequency and phase, but are either unable to use the tools to their full potential and are therefore in need of assistance in using the tools to their full potential
Understanding High Vibration

How do we help?

We have a team of trained engineers, experts, technicians equipped with the right tools. They can help you carry out Vibration Measurement and Analysis. They can help you understand the following:

  • Which of your Rotary Equipment are in Good Health and which of them need attention? We do this by comparing observed vibration levels with Severity Charts such as ISO 2372 or ISO 10816
  • What is the underlying cause of high vibration in the equipment needing attention? Problems that can be detected are:
    • Unbalance
    • Looseness
    • Misalignment
    • Resonance
    • Electrical Faults
    • Several Others
  • What is the recommended action to be carried out to bring down the Vibration to acceptable levels? We can also help carry out the recommended action such as:
    • In-Situ Dynamic Balancing of Rotor
    • Laser Alignment across Coupling
    • Suggest Design Changes in event of Resonance

Ways in which we deploy the Service

One-time Service

In this type of Service, the expert is deployed once against a Work Order and carries out the entire agreed scope of work in a single visit of an agreed duration. On completion of the visit, the expert submits an Analysis Report with recommendations

Periodic Visits

In this type of Service, the expert is deployed at an agreed interval to carry out Vibration Measurement and Analysis. This helps the Customer establish a Trend and plan Maintenance actions. Report is provided on each Visit by the Expert

Annual Maintenance Contract

In this type of Service, a team of Helpers, Data Collectors and Analysts are deputed to a site based on the site requirements. They report to the site everyday and help the Customer in taking care of their Rotary Assets.
