Vibration Monitoring Equipment

March 1, 2016

Vibration monitoring equipment is important for construction companies to monitor vibration caused by their piling and demolition works. Vibration monitoring equipment is a kind of equipments for a predictive maintenance method which allows early problem detection in rotating machinery, such as: gearboxes, fans, shafts, motors, compressors, pumps, mixers, driers – in fact, almost any type of active machinery.

In short, vibration monitoring equipment has a big role. It is known that vibration monitoring will identify component faults – such as defective bearings & misalignment – and enable you to take maintenance action before a failure in service. The benefits of using condition monitoring in this way are significant, when you are predominantly operating in a reactive maintenance mode (or even predominantly in a traditional “fixed-interval, time-based” mode of preventive maintenance).

Vibration analysis is the most commonly used technology to monitor. The frequency of the vibrations can also be mapped since certain frequencies will only be present when conditions that indicate an impending defect are present. Comparison of the vibration spectra of new vibration monitoring equipment versus equipment that has been used will provide the information required to make a decision when maintenance intervention is required.

For vibration analysis on a bearing, the PF Interval will vary depending on the type of failure detected, the type of bearing installed, the severity of its operating cycle, the type of lubrication applied, ambient temperature conditions and many other factors. Any error tends to be on the conservative (i.e. too frequent) side.

But nevertheless, many examples of bearing failures that have occurred undetected, despite these bearings being monitored at these conservative frequencies. To date, little concerted effort has been made to attempt to improve the accuracy of PF Interval estimation for vibration monitoring equipment.

Even if you do not take a completely holistic approach to equipment condition, there are still significant benefits to be had from integrating process control data with vibration monitoring equipment. For example, it is known that certain electric motors will display higher vibration when operating under low loads, than when they are operating under high load.

In order to achieve greater integration, you need each vibration monitoring equipment to be able to interface with one another using common standard protocols. Today, you have seen condition monitoring suppliers such as CSI, Predict-DLI and others offer integrated condition monitoring software, which permits the effective integration of oil analysis, vibration analysis and other condition monitoring data into combined reports.

You have also seen an increasing number of CMMS vendors include a “Condition Monitoring” module within their software.

Unfortunately, you are yet to see an effective solution that integrates these two solutions into an effective whole.

Anyway, vibration monitoring equipment can be applied to many conditions. Condition monitoring of temperature, analysis of machine vibration, over voltage or current and liquid level are the most common. In effect, any condition that can be detected by a sensor can be monitored.

One of vibration monitoring equipments you can choose in the market is The HI 3600. This vibration monitoring equipment will accommodate whatever sensing mechanism and monitoring range is best suited for you and your applications, regardless of whether it involves probes, accelerometers, or high/low frequencies. With an additional 16 channels, you can monitor any parameter in the process (such as temperature, KW Load, or position), tying them into the 3600 Machine Monitor. Even, it is completed with Hardy-Links Connectivity structure of the 3000 Controllers to allow you to connect to your process from anywhere.
