Dynamic Field Balancing

In-Situ Dynamic Balancing

In-situ dynamic balancing, also known as on-site balancing or field balancing, is an essential process for optimising the performance, reliability, and safety of important components of rotating equipment in various industrial operations. This process involves balancing a rotating machine while it’s still installed in its operating environment rather than disassembling or removing it to a specialised balancing machine.

As a sophisticated technique, in-situ dynamic balancing effectively identifies and rectifies imbalances within the equipment, significantly reducing vibration that can lead to operational inefficiencies and costly downtime. By addressing these imbalances, in-situ improves equipment efficiency, increases lifespan, and reduces the risk of damage and unplanned interruptions. 

The methodology includes a systematic approach that involves assessment, measurement, correction, verification, and documentation, ensuring that machinery operates efficiently within its designated environment.

What Is In-Situ Dynamic Balancing?

In-situ dynamic balancing refers to the balancing of rotating machinery directly at its installation site without the need for disassembly or transportation to an external balancing facility. This technique is similar to balancing a car tyre but is used on a much larger, more complex industrial scale.

Over time, various factors can lead to imbalances in machinery components such as rotors or impellers. These imbalances may arise from manufacturing defects, wear and tear due to prolonged use, or operational stresses during normal functioning.

The process begins with a thorough assessment conducted by trained professionals who examine the machinery for any signs of imbalance or vibration-related issues. This initial evaluation is crucial for determining the extent of the balancing process and identifying specific areas that require intervention.

Next, specialised equipment such as vibration analyzers and portable balancing devices is employed to measure the vibrations produced by the machinery. These measurements provide valuable data on amplitude (the strength of the vibrations), frequency (the rate at which they occur), and phase (the timing of vibrations in relation to each other). This information enables professionals to pinpoint the exact locations and severity of imbalances.

Advantages of In-Situ Dynamic Balancing over Traditional Methods

Unlike conventional balancing techniques that often require disassembly, storage, and transportation to external facilities, in situ dynamic balancing allows for adjustments while the equipment remains fully operational at its actual location.

This is particularly crucial for various types of machinery, including industrial fans,  rotors, compressors, gears, crankshafts, pumps, turbines, motors, process rolls, high-speed tooling, and other rotating components.

Dynamic balancing is specifically designed to mitigate vibrations caused by imbalances in rotating elements. An unbalanced machine can lead to several detrimental effects:

  • Increased Wear: Excessive vibration can lead to faster deterioration of some components.
  • Reduced Lifespan: Machinery that operates out of balance tends to affect the equipment performance and result in a shorter operational life.
  • Decreased Efficiency: Imbalances can lead to increased energy consumption and reduced overall efficiency.
  • Safety Hazards: Excessive vibrations can pose risks to safety and security not only to the machinery but also to personnel working nearby.

Industries can improve machinery performance and extend operational life by effectively identifying and correcting these imbalances on time using in-situ dynamic balancing.

Benefits of In-Situ Dynamic Balancing

In-situ dynamic balancing offers several advantages over traditional methods. One of the most significant benefits is that it can be performed without dismantling the machinery. This minimises downtime and eliminates the logistical challenges of transporting large, complex equipment to an external facility. This method also mitigates the likelihood of damage or misalignment caused during machine disassembly.

Likewise, in-situ analysis provides more precise results, as the machinery is tested under actual operating conditions. Factors such as temperature, load variations, and environmental influences are considered, ensuring that corrections are specifically tailored to the operating environment. This could lead to better machine performance and reduced vibration levels.

The In-Situ Dynamic Balancing Process at Ocean-me

The in-situ balancing procedure followed at Oceanme consists of several key steps:

  • Assessment: A comprehensive evaluation of the equipment is carried out by a team of highly trained and experienced professionals at its installation site. This is the initial assessment and includes examining the condition of the machinery and identifying any vibration-related issues. Understanding these factors is important for determining the scope of the balancing process and pinpointing specific areas that require intervention.
  • Measurement and Analysis: Utilising specialised equipment such as vibration analyzers that measure changes in vibration frequency, displacement, and acceleration and other portable balancing devices, specialists measure the vibrations produced by the machinery. These measurements yield vital data regarding amplitude, frequency, and phase, allowing for precise identification of the locations and severity of any imbalances.
  • Correction:  At this stage, the initial assessment and analysis have been completed. Based on the collected data, the professionals determine the necessary corrective actions, such as weld-on weights, adhesive weights, or clamp-on weights. Adjustments may also include repositioning components or modifying their geometry to enhance balance.
  • Verification: After implementing corrective measures, professionals re-measure vibrations to confirm that imbalances have been adequately addressed. This verification step is essential for validating the success of the balancing process. If vibrations remain outside acceptable limits, further adjustments are made until optimal balance is achieved.
  • Documentation: Proper documentation is maintained throughout the in-situ dynamic balancing process, which includes initial measurements, corrective actions taken, final measurements, and recommendations for ongoing maintenance. Such records serve as a valuable resource for future inspections and help track the history of the machinery’s balancing efforts.
