In general, most cooling tower fans run at a speed somewhere between 90 and 300 revolutions per minute (rpm) while motors for cooling towers generally run at speeds around 1,500 to 1,800 rpm. Two organizations have developed vibration standards for cooling tower fans. The Cooling Technology Institute (CTI) Vibration Standards are presented
Cooling towers are a logical choice for vibration monitoring. Due to their often critical role in maintaining operational efficiencies. We use vibration analysis to improve reliability and extend the lifetime of cooling tower equipment. How It Works. The machinery generally consists of three phases: motor, gearbox, and fan.

configuration of cooling towers, there is a single common denominator: they need to be readily available. This single criterion requires the most effective condition monitoring and system maintenance procedures to be put in place. At the heart of each cooling tower is a large fan system, providing forced air to the heat exchangers.
Remote monitoring of cooling towers is the best way to ensure that developing faults are addressed before they can lead to failure. A vibration-monitoring system can detect all of the failure mechanisms previously discussed. Distinctive alerts can be sent to the control room, where a trained analyst can review the vibration signal to positively ...
Using Remote Vibration Monitoring in Cooling Towers. When selecting the best condition monitoring approach, vibration monitoring is a useful method of catching changing conditions for any rotating asset and is ideal to monitor cooling tower fan motors, which are a common route cause of failure.
Vibration-Management Options for Monitoring Cooling Tower Operation. Mechanical Vibration Switch. A mechanical vibration switch (figure 2) is the simplest way to manage vibration. The switch is typically mounted onto the mechanical equipment support and connected to …
A vibration switch detects shock and vibrations inside your cooling tower and essentially shuts the tower down or sends out an alarm if they reach a pre-set level. This is probably the most important and inexpensive component you can make in your tower. The vibration switch is constantly monitoring the cooling tower to insure there are no ...

One or two vibration severity setpoints are user-adjustable in velocity units, and the 440 comes standard with a powered 4-20mA output representing vibration severity. These features make the 440 a flexible option, at an economical price point, for machine vibration monitoring. Applications: Cooling Towers. Pumps. Compressors. Motors. NSI Solution:
Over the years, several false vibration alarms have come in at the control center showing severe vibration at the cooling towers, when in actual fact it was the building vibration that had increased. Figure "4" is a trend comparing mill vibration to actual fan vibration.
Our advanced condition monitoring (ACM) of data from key components in our client's 250 MW combined cycle gas turbine plant detected a significant increase in vibration as well as a change of temperature during a turbine start-up: Clear evidence for the loss of mass in the turbine blade and a …
A modular continuous monitoring system, such as the Hardy Instruments DI 5500 Series, offers low cost "building blocks" that are ideally suited to monitoring cooling towers. The modules include vibration detection modules, dual set point modules, and relay modules. Other modules are available but these three types can be combined to provide a ...
