Using condition monitoring to forecast and diagnose problems

Careful condition monitoring by keeping track of any subtle changes in machines overtime can help avoid failures and costly downtime.

07/27/2017


One of the many factors in establishing an effective maintenance program is the ability to diagnose problems. Having the ability to fix those problems early is key before they become a larger issue. Having the proper maintenance techniques in place allows for the repair or replacement of equipment on your terms. You no longer have to wait for them to fail, this results in unexpected and costly downtime.

It is the process of monitoring a piece of equipment and determining if the condition is changing over time. Changes include an increase in temperature or vibration as well as a decrease in power or productivity. Even a slight change in the condition of the machine signifies potential problems.

An important factor to consider when using condition monitoring is that it is not a sole tool to use. It is a potent tool in detecting and diagnosing problems within the machinery. It is also a method of last resort. Once problems are discovered with equipment, it may already be too late.

One piece of the toolbox

Using other preventative maintenance techniques helps rule out problems before they become detectable. Those different types of maintenance techniques include infrared and ultrasound technology.

Write down information about the condition of the equipment. Don't expect the equipment operator to recognize changes. Changes in the equipment's operation might be gradual and undetectable. Comparing notes over time goes a long way in helping detect problems.

Another important factor is routine maintenance. Maintaining the equipment on a regular schedule helps to delay issues. Lubrication and regular cleaning are some everyday tasks that work with an established condition monitoring program. Using a combination of these tools may be part of the preventative maintenance program, but it also is good operating procedures.

Finally, it is important to get the operators on board with the program. They need to voice their concerns and opinions about the equipment they are operating. Provide regular instruction and a means of communication that works for everyone involved.

A plant must be run efficiently with data and schedule maintenance strategies to avoid failures and costly downtime.

Annual Salary Survey

Before the calendar turned, 2016 already had the makings of a pivotal year for manufacturing, and for the world.

There were the big events for the year, including the United States as Partner Country at Hannover Messe in April and the 2016 International Manufacturing Technology Show in Chicago in September. There's also the matter of the U.S. presidential elections in November, which promise to shape policy in manufacturing for years to come.

But the year started with global economic turmoil, as a slowdown in Chinese manufacturing triggered a worldwide stock hiccup that sent values plummeting. The continued plunge in world oil prices has resulted in a slowdown in exploration and, by extension, the manufacture of exploration equipment.
