Another important skill a data center maintenance worker needs is an understanding of the fundamentals of lubrication. Although lubrication may seem simple, there is a good deal of skill behind knowing proper lubrication methods, quantities, and the difference between over and under lubrication. And because under or over lubrication can cause serious problems such as…

We have been privileged to both sell tools and shaft alignment, vibration testing, and precision maintenance training for several different data centers throughout the US. Most of the maintenance technicians we encounter have solid electronics and computer skills, but some are less experienced with mechanical skills. Thus, some of the challenges faced by these maintenance…

The emergence of portable computers, the internet, and the ubiquity of portable smart devices has given rise to a new type of industry–the data center. A data center is simply a building used to house computer servers. While these servers may be used for many different types of data storage, their requirements for in-house…

From time to time, when performing route-based vibration analysis, you run across situations where access is limited to a data collection point. For example, this large pump below. Climbing up a structure to collect vibration data is unsafe and keeping a ladder stationed nearby can cause headaches as well. A simple solution is to permanently…

Sometimes machines need to be added to a route that is already established. This is quite easy to do in the Nest. After you have collected all the pertinent information including machine name, RPM and horsepower (at a minimum) go into your Nest home screen and select “set up machine”. Once into machine set up…

Taking the ONEPROD Falcon to the field is a big part of the 2-day training we provide on our entire Falcon line of condition monitoring tools. When we go to the field we always find interesting issues to analyze and discuss. A recent check of a centrifugal pump yielded one of those issues. The pump…

A common vibration signature on equipment is looseness. There are two types of looseness: structural/fastener, fit between rotating components. For this discussion, we will focus on structural and fastener looseness. Typically, it is highly directional, occurs at 1xRPM, and will look similar to this spectrum. In this case, the vibration was confined to the vertical…

Accelerometers by nature are sensitive tools. This sensitivity is heavily influenced by how the sensor is mounted. Standard accelerometers are mounted several ways based on need and application. Typical route-based data collecting will be done with a rare earth magnet. The magnet can be either flat or a two-pole type. This provides good data with…

Unbalance and runout are two terms that we hear frequently in the predictive maintenance community. Both unbalance and runout can be serious issues and need to be addressed to prevent inefficient functioning and damage to machines. Unbalance occurs due to corrosion, erosion of the fan wheel, or if a correction weight is removed. Runout occurs…

We often hear about how to correct unbalance in rotating machinery, but to correct unbalance, it is first necessary to accurately diagnose what type of unbalance your machine is experiencing so that you can take the proper action to correct the problem. In this post, we will go over the three types of unbalance you…

As the resurgence of manufacturing and processing in America continues, the requirements on all of us to do more with less will only grow more important in order to reach the needed profitability goals. Combine this downward pressure with the diversity of today’s plants and their mechanical components, and the overwhelming gap of skilled workers…

Determining the RPM (revolutions per minute) of your machine is an important part of conscientious condition monitoring. Significant loss of time and productivity can occur if your machinery is not operating at the correct RPM. That’s why it is imperative to be able to quickly and accurately determine the RPM. In this post we…

One of the basics of condition monitoring is establishing routes so that you can efficiently check the diagnostics of all your machines in an orderly, structured way which does not disrupt the daily tasks of other workers in your plant. Routes help to guide the mechanic to the next machine in a logical order rather…

The Fixturlaser Smart Machine Checker (SMC) is a great mechanic’s tool, for evaluating the overall health of rotating machinery. But did you know it’s also a lubrication tool for greasing bearings? Let me explain. One of the vibration measurements in the SMC is called Bearing Defect Factor. The Bearing Defect Factor is a measurement of…
