Condition Monitoring

In most industrial plants where many different processes are required to work together reliably and efficiently to achieve an end goal, condition monitoring equipment is a pre-requisite.

CFW Fans can install condition monitoring systems on our industrial fans during manufacture, or retrofit to existing equipment. Where routine maintenance is too costly or cannot adequately guarantee performance, condition monitoring systems will give early warning about potential equipment problems that could lead to failures before scheduled maintenance can be performed. Operational data is periodically monitored and compared with acceptable levels of performance to get an indication of the functioning of the machine. This makes it a key element of preventitive maintenance programmes (PMP's)

Condition monitoring is an efficient and proactive approach to scheduling and managing maintenance so that resources can be directed where needed. At the same time, it does not intrude on the production process. Condition monitoring has several advantages:

  • Monitoring equipment, common to all types of rotating machines, can be used to alert maintenance personnel when impellers exceed predetermined vibration levels, and/ or bearing temperatures exceed specified limits, are typical examples
  • Substantial financial savings on production losses and repairing secondary damage by pre-empting breakdowns
  • Peace of mind for investors, managers and maintenance personnel

Condition monitoring is often associated with the use of a criticality index. Relevant information such as the purpose, redundancy, repair costs and impact of poor functioning or failure of a machine are used to classify it as critical, essential or general purpose machinery.

Critical machinery

is absolutely necessary to the functioning of the plant, making it worthwhile to collect data on its functioning continuously even at high costs

Essential machinery

is important for factory operations but can be dispensed with in an emergency. This includes redundant machinery. Control and testing of such equipment is still undertaken and backup plans are put in place.

General purpose machinery

may be monitored only periodically using handheld data collection.

Condition monitoring equipment consists of sensors that gather information (such as vibration, temperature, pressure and so on), transmitters that forward the information to a central monitoring point via screened cables. Depending on the client’s requirements, this information can be displayed in a control room, and/or trigger alarms to alert the client on-site, or via the internet.
