Vibration Measurement – Overall Vibration Severity and Vibration FFT analysis.

Vibration Measurement

Since man began to build machines for industrial use and started using motors to power them, problems of vibration reduction and isolation have started to surface and create machinery failures. Over the years, vibration isolation and reduction techniques have become an integral part of machine design. Additionally, the need for accurate vibration measurement and vibration analysis has grown. During the last decade a whole new technology of vibration measurement has been developed which is suitable for investigating modern highly stressed, high speed machinery. Using sophisticated accelerometers to convert vibratory motion into an electrical signal, the process of vibration measurement and analysis is comfortably performed by the versatile abilities of electronics.

Vibration Measurement can predict machinery failure

The Need for Vibration Measurement

Vibration Measurement and Testing involves measuring vibration at machine site. The measured vibration is in the form of RPM values or vibration amplitude vs time graphs showing the severity of vibration. Vibration needs to be measured at different points on the machine and connecting shafts. Also, vibration measurement needs to be done in various orthogonal planes to study the impact of vibration on ground structure and machinery itself.

Vibration Measurement

There were 2 ways of understanding machine condition with vibration testing:

★ Vibration / Bearing measurements indicating vibration severity.
★ Vibration Spectrum Analysis / Vibration FFT Analysis.

Overall Vibration Measurements

On-Site Vibration measurements provide accurate feedback of the equipment condition by measuring and examining the overall levels of vibration due to machine conditions. These vibration measurements help to identify problems in normal machine working. These vibration measurements look at the entire vibration signal in low frequency bandwidth and provide a single number for overall machine vibration. If the machine vibration or noise is higher, this vibration measurement value will increase. The Plant Maintenance Teams can then use these vibration measurement reports to make quick go or no-go decisions by comparing the vibration measurment values to ISO Standards (ISO 10816) and trending the results over time.

We provide Vibration Measurement Services for Machinery Installation & Machine Predictive Maintenance through Machinery and Site Report Cards. The Site Vibration Report Cards are prepared by measuring the overall vibration severity at a host site when all other machinery are working. These Site Vibration Reports can be used for planning new machinery as these will provide complete information about site vibration levels. These levels can then be judged against machinery vibration tolerance specifications. We also provide vibration isolation & mitigation assistance in case the site vibration levels are higher than those prescribed by the machine manufacturer.

Why do I need Vibration Monitoring?

Vibration monitoring can tell us a great deal about a machine.
● Imbalance
● Misalignment
● Flow problems
● Bearing faults
● Looseness
● Electrical faults in AC and DC motors

vibration-measurement-importance-of-vibration-measurement

Importance of Vibration Measurement

Routine monitoring
● Tests are typically performed every 30 days. In some cases this can be extended to 90 days.
● Tests are performed at each bearing location
● Data is collected at the Horizontal, Vertical and Axial points.

Vibration Spectrum Analysis

For Vibration Spectrum Analysis, Vibration specialists use vibration analyzers for sophisticated analysis of machine condition. here the vibration spectra (vibration amplitude versus frequency) is analyzed. The vibration spectra can provide detailed information about disturbing frequency vibration at site. Also manintenance teams can create a baseline for the tested equipment, and trend the results over time. This sophisticated analysis not only provides information about whether there is a problem, it also helps understand the root cause and time to failure. This type of vibration testing requires a strong understanding of the vibration spectra and equipment’s maintenance history.

How to Reduce Vibration by selecting the correct Anti-Vibration Pads for Industrial Machinery.

Many Industrial machines generate Vibrations and these vibrations are damaging the internal parts, bearing, gears and shafts of the machine. Vibrations in Generators can travel through an entire building structure and cause annoyance and constant irritation to the building inhabitants. Similarly, a large compressor mounted on a factory rooftop can create massive vibrations during intermittent start-ups and stops. While you can reduce vibrations in these machines by following proper maintenance schedules, the truth is that eventually when the machine (generator or compressor or motor or pump) gets older, the maintenance costs and maintenance downtime increases. In this case, vibrations are not totally UN-avoidable. The machines will vibrate. But what can be easily accomplished is mounting the machine on new Anti Vibration Pads. The Anti Vibration Pads are made from vibration absorbing materials like springs, rubber or air. The major advantage of these Anti Vibration Pads is that while they do not stop the actual vibrations inside the machine, they can effectively isolate all vibrations being produced by the machine. In other words, the vibrations produced by the machine are not transmitted beyond the Anti Vibration Pads.

Reduce Vibration with the Help of Anti Vibration Pads

Vibration-reduction in industrial-generators with the help of anti-vibration-pads.

Let’s look at the diagram above illustrating the vibration isolation property of the AntiVibration Mounts. The diagram shows the side-view of a Genset installed on our AntiVibration Mounts (AV Mounts). While the Generator vibrates and makes the liquid placed on top of it to vibrate vigorously, the bottom frame of the generator is vibration isolated. The above is a Demonstration of Vibration Reduction by Anti Vibration Pads for a Generator/Compressor/Motor/Pump. We can clearly see that the generator is producing massive vibrations and is thus vibrating the glass full of liquid on top. The generator is further flexibly mounted on Anti Vibration Pads with fail-safe design. The Vibrations are transmitted by the generator into the AV Pads. The AV-Pads being made from high quality elastomeric rubber compounds are able to absorb these vibrations with ease. The design of the Anti Vibration Pads is such that there is no direct metal-to-metal path for the vibrations to travel. This vibration isolation is possible using our superior Anti Vibration Pads. Additionally, the design of the Anti Vibration Pads plays a critical role in damping Generator / Compressor / Motor / Pump Vibrations. The vibrations in these machines are typically produced due to imbalanced rotation. This results in vibrations that are vertical and horizontal in nature. The Anti Vibration Pads should be able to absorb both these vertical and horizontal vibrations in all planes. Apart from these vertical and horizontal vibrations, these machines also produce heavy torsional / rotational vibrations. The Anti Vibration Pads design should be capable of isolating and absorbing these Rotational Vibrations.

Vibration is produced by all Industrial Machinery. It is essential to block all high amplitude vibrations generated by these rotating machines. Thus, with the use of simple and effective Anti Vibration Pads, we can greatly control, absorb and isolate the harmful and annoying vibrations that get transmitted from these machines. Another added advantage of these Anti Vibration Pads is the reduction in noise transmission as the vibration is effectively controlled and isolated.

So, how do you decide which Anti-Vibration Pad to use for your industrial machine like generator, compressor, pump, engine or heavy-duty motor?

Anti-Vibration Pads for Damping Vibrations in Industrial Heavy-Duty Compressors

Compressors generate vibrations and these vibrations damage the internal parts, bearing, gears and shafts of the Compressors. A large compressor mounted on a factory rooftop can create massive vibrations during intermittent start-ups and stops. We supply Anti Vibration Pads to Air Compressor manufacturers. While you can reduce vibrations in these machines by following proper maintenance schedules, the truth is that eventually when the machine (compressor) gets older, the maintenance costs and maintenance downtime increases. In this case, vibrations are not totally UN-avoidable. The machines will vibrate. But what can be easily accomplished is mounting the machine on new Anti Vibration Pads. The Anti Vibration Pads are made from vibration absorbing materials like springs, rubber or air.

CYMAATICS Design – Some Common Types of Vibrations in Compressors

The two predominant types of vibrations in Compressors are Lateral and Rotational (twisting) vibrations. In Lateral Vibration, the whole compressor moves in the x-y-z domains i.e. up-down, left-right sideways and front-back movements. An example of the lateral vibration is the excessive ringing/movement of external piping due to resonance. When the vibration of external piping becomes excessive, it is almost certainly because some vibration within the compressor system is occurring at a frequency near the natural frequency of the piping structure.

vibration-isolation-pads

Rotational vibration occurs from within the compressor system due to unbalanced rotating loads. A common occurrence of rotational vibration is an extreme vibration along the crankshaft whose frequency is the same as shaft speed. This type of rotational vibration is usually due to unbalance forces acting on the crankshaft caused by unequal weights in piston pairs. Both the Lateral and Rotational vibrations can be easily controlled and damped by our Anti vibration pads specially designed for this purpose. The design of traditional Anti vibration pads only isolates the up-down vibration or at max one degree of x-y vibration. But in our Anti vibration pads the complete 360 degrees vibration isolation in the x-y plane is possible along with controlling vertical vibration and more importantly isolating rotational vibrations.

Vibration-pads-for-compressor

Every system has one or more natural frequencies of vibration. If an excitation occurs at one of these frequencies, a structural system will tend to ring and move excessively. Existing vibration levels will be exaggerated and damage to the machinery will occur at an accelerated rate. in case of resonance of one part of your air compressor machinery structure, there are several steps you can take to correct this condition.

Some Important Steps to Control Vibration in Compressors:

1. Be sure the Anti vibration pads and other anchoring hardware are properly torqued. Loose mountings often cause general looseness that mimics resonance.
2. Check the Anti vibration pads by checking the creep developed in them. This can be easily checked by measuring the height of the Pad while installed and then checking the height again 3-4 hours after removing the Pad from any external pressures. The Anti vibration pads should return back to within 95% of it’s original uncompressed height.
3. Vary the operating speed of the unit to change the frequencies of the exciting force(s). The Anti vibration pads will typically have resonance frequencies near the 8Hz-12Hz range, therefore system frequencies must be kept away from these resonant frequencies.
4. Add weight to the compressor structure that is resonating. Changing the mass of the structure changes its natural frequencies.
5. Vibration in pipes may also be cured by adding rubber-bush bracing and AntiVibrating Hangers.

Application Usages for Electrical Panel Mounts

★ Mounting control panels on diesel gensets producing high vibrations.
★ Fail-safe Electrical Panel Mounts for movable equipments,
★ Mounting Electrical Control Panels for movable surgical equipment,
★ Panel Mounts can be used for mounting LCD screens onto high vibration experiencing walls.

Vibration leads to early component failures in electrical panels. In an electrical panel mounted on a genset frame, the vibrations from the genset are continuously disturbing the components and switches inside the panel. These continuous vibration lead to very high panel failure rate and also disturbing genset functioning. The electrical panels isolated with the AV mounts provide higher degree of passive vibration control.
