Implementing a reliability program in your facility can have numerous benefits. Just a few of these include: Greater efficiency Reduced costs Better organization Increased understanding of machine trends Less frustration in the workplace Streamlined process The list could go on. Few of us are likely to disagree that a reliability program for your machines and…

Vibration analysis is a useful way to monitor machine health. Many plants have implemented regular vibration analysis plans to ensure the condition of their machines is being checked at regular intervals and so, if an issue comes to light after spectral analysis, a solution can be pursued. When analyzing vibration, it is important to…

Bearings are essential to all rotating machinery. They are small but mighty–if bearings aren’t healthy, a machine will not function at optimum levels. In this post we provide you with some information and best practices for bearing installation and maintenance. Let’s start with the very basics–what are bearings? A bearing is a machine component that:…

How do you calculate the RPM (Revolutions Per Minute) of a Variable Frequency Drive (VFD)? This is what we will go over in this post. A Variable Frequency Drive, which is most often abbreviated as VFD, is a type of mechanical drive system used to control AC motor speed and torque by varying motor input…

Proper lubrication of bearings is essential if you want to maintain your machines at optimum levels. Did you know it is estimated that 40-50 percent of bearing failures are the result of improper greasing/lubrication? That’s a significantly high percentage! So what can you do to ensure you are properly lubricating your bearings? Two things…

Do you know how to calculate F-MAX or even what F-MAX is? Knowing how to calculate F-MAX is an important part of vibration analysis because many different types of faults can be shown at multiples of the running speed, which is otherwise known as 1x. But first, what is F-MAX? F-MAX means “Frequency Max.” This…

A key purpose of vibration analysis is to detect bearing problems before bearings fail and damage is done. This, of course, means that bearings will need to be replaced. Proper bearing extraction and installation is important to extending the life of bearings as well. First, it is important to know when you need to replace…

Before you can implement a condition monitoring program, it is important to document certain information on your machines. This post will hopefully help you organize your routes and efficiently implement a predictive maintenance plan. Even better, you can download our free Machine Data Sheet which will give you fields to fill in all the important…

Documenting and saving alignment data is critical to being able to achieve repeatable shaft alignments. It also helps you maintain an effective predictive maintenance plan that will ensure your plant runs smoothly. When a machine is experiencing a problem, it will save a lot of time if you can look back on recorded data from…

One key bit of data required when collecting data or analyzing it is accurately pinpointing the RPM. When we set up schematics in the Machine Set Up module we tell the software what the RPM is here. When setting up a machine in the Nest you can choose either fixed speed, variable speed with keyboard,…

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…

Just like for any plant, it is critical for the data center to sustain minimal to no interruptions to normal processes. The amount of (often sensitive) data housed in the data center servers makes it imperative that data centers continue to run, no matter the conditions. This is why backup generators are so important. In the…

In this installment of our data center maintenance series, we will discuss fans. While HVAC chillers ensure cool water supplied to fans for cool air is pumped into the servers in a data center, fans ensure that the hot air from the servers is removed efficiently and redirected to the Computer Room Air Conditioning (CRAC)…

Cooling towers and related components such as chilled water and condenser water pumps are another common type of data center equipment. On a basic level, cooling systems in data centers remove heat from one element and redirect it to another. A cooling tower is the depository for the excess heat given off by data center…

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…
