Vibration Measurement Techniques in Power Plant

Vibration measurement is complex because of its many components: displacement, velocity, acceleration, and frequencies. Vibration measurement is an effective, non-intrusive method to monitor machine condition during start-ups, shutdowns and normal operation. Regular vibration monitoring can detect in a power plant shaft lines, deteriorations and defects of a number of various structural mechanical conditions, for example cracks, bearing faults, coupling damage, imbalance as well as interruptions in the electric grid.

Gas Turbine Vibration Monitoring

Vibration measurements are commonly considered to be a sound indicator of a machine’s overall health state (global monitoring).The general principle behind using vibration data is that when faults start to develop, the system dynamics change, which results in different vibration patterns from those observed at the healthy state of the system monitored.

Vibration Analysis on a conveyor unit

Belt conveyors are an integrated transmission and carrying mechanism with length sometimes extending several thousand meters. In traditional design and analysis of belt conveyors, vibration and impact are usually ignored and only static design is considered. However, to ensure the safety of conveyor operation for this restricted analysis, designers must increase the safety factor, which increases production costs. Many research groups have conducted dynamic analysis of large belt conveyors to reduce production cost and optimize conveyor performance. The conveyor belt was first modeled as an elastic body and then a viscoelastic body to incorporate viscoelastic characteristics of belt cover layer.

Condition Monitoring Techniques, Applications, and Tools

Condition monitoring starts with basic inspections. Small changes, like abnormal heat or pressure, strange sounds, excessive vibration, or a different smell, are often signs that something is going haywire. There are several machine condition monitoring techniques that are used for the assessment of machine conditions.

Vibration Analysis

Vibration analysis is the most prevalent method used to monitor the levels and patterns of vibration signals within a component, machinery or structure, in order to detect abnormal vibration events and then using that information to analyse and evaluate the overall condition of the component, machinery or structure. In short, vibration analysis helps you monitor and detect issues using vibration data

Vibration Testing on Shakers

Vibration Testing is one such environmental test critical to the design process. All closed-loop vibration tests, consists of four main components: a vibration controller, an amplifier, a shaker, and a feedback sensor, together, these four components make up a vibration testing system. ETS Solutions Asia instruments vibration controllers control electrodynamic and hydraulic shakers from tabletop to warehouse size systems.

Condition Monitoring, What is it?

Condition monitoring is the activity of periodically checking equipment, with the aim that the equipment is in a healthy condition so that the equipment can work according to its function. Adopting proactive predictive maintenance techniques is much more than just good plant management, it is good business. Anticipating machine failures before they occur, allows you to catalyze improvements that create positive ripple effects for the entire enterprise.

Vibration Resistance of Electrical Equipment

Shock and vibration resistance gives information concerning the robustness of the mechanical design of a device. The methods for evaluating the vibration resistance are defined in IEC 60068-2-6 and IEC 60068- 2-64. Electrical and electronic equipment are exposed to vibration in many applications and must withstand this without any degeneration, or even failure, in their function. Therefore, manufacturers of electrical and electronic devices put a great deal of effort into ensuring their instruments are prepared for such applications.

Random Vibration Testing

Random vibrations are the oscillations of mechanical systems excited by environments that vary randomly in time and, perhaps, space. Practically all real physical systems are subjected to random dynamic environments, and many systems will fail due to the effects of these exposures.

Sine Vibration Testing

Sine Vibration Testing may be considered as the most basic vibration testing method used. This type of vibration testing requires less complex parameters compare to other type of vibration testing. Knowing the nature of sinusoidal signal, makes this type of vibration testing easier to understand and to get familiar with. Though, easier to understand does not make it less important compare to other type of vibration testing. Sine vibration testing may still be at the top rank when we are thinking of dynamic characteristic measurement.

Vibration Testing for Aerospace Payload_NASA-STD-7002B

National Aeronautics and Space Administration (NASA) is one of the most well-known aerospace agencies in the world. Therefore, NASA standards are also used as reference for testing laboratory to run testing related to component or sub-system of a spacecraft. NASA-STD-7002B is part of NASA standard that provides a standard set of flight hardware test requirements.

Vibration Controller, The Brain of Vibration Testing System

While accelerometer is playing the role of feedback sensor at vibration testing system, then vibration controller can be considered as the "brain" of it. Vibration controller is the device that sending the "instruction" in the form of drive voltage during vibration testing, and also interpreting the feedback signal coming from the accelerometer.

Condition Monitoring System, from Data Collection to Defect Diagnosis

When we have large size of rotating machinery, performing corrective or preventive maintenance may not be so easy anymore. Based on the periodicity of the data collection, machine health condition monitoring can be classified into below categories: 1. Periodical Monitoring; 2. Semi-Online Monitoring; 3. Real Time Monitoring

Data Acquisition System, from Data Recording to Post Processing

In order to be able to collect data from actual service environment, we will need at least two components: sensor/transducer and data acquisition/recording/logger system. Sensor will be responsible to convert the physical measurand into electrical signal (voltage, charge, capacitance, resistance) and that can be transferred and read by data acquisition system.

Vibration Measurement, Key Factor to Run Valid Vibration Test

When some of the test engineers try to run vibration test to simulate the actual vibration experience, they may experience a situation when they think their vibration test result is not valid. Why is it not valid? One simple answer, because the test procedure is unable to re-produce the same failure mode.
