The Importance of Mechanical Skills in the Data Center: Bearing Replacement

| | | |

By on July 15, 2019

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 […]

By on June 26, 2019

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, […]

The Importance of Mechanical Skills in the Data Center: Lubrication

| | |

By on June 11, 2019

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 […]

Emergency Generators: Making it Possible for the Show to Go On

| | | |

By on May 23, 2019

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 […]

Data Center Fans: Blowing More Than Hot Air

| | | |

By on May 20, 2019

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: Moving the Heat Away from Where it Isn’t Wanted

| | | | | |

By on May 14, 2019

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 […]

Training or No Training, It’s a Leadership Question

| | | |

By on May 1, 2019

It’s no secret that there is a shortage of skilled labor in manufacturing, specifically in machinery maintenance. Therefore, those in leadership positions must answer the question “training or no training?”. Another way to look at it is, am I willing to invest in the workforce to better insure a more reliable operation? I wrote a […]

Balancing How To #3-Where and How to Place and Affix a Trial Weight

| |

By on April 25, 2019

Once unbalance is determined, the original unbalance run (amplitude and phase) is measured, and a trial weight size is determined, the next step is where to place the trial weight. If you have no balancing record for this rotor, where to place the weight is little more than a guess.  But there are some things […]

Visual Inspection of Couplings and Machinery Components

| | |

By on March 27, 2019

Some things just don’t pass the “eye test”.  Your eyes are actually great tools for seeing things that are not straight, not plumb, not level (pictures hanging on a wall for example), not right.  Many times, just by looking at a coupling you can tell “it’s not aligned”, and you are usually correct. Visual Inspection: […]

Adding Machines to an Existing Route in Your Nest Software.

| | |

By on February 28, 2019

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 […]

A Vector Approach to Single Plane Balancing

| |

By on February 7, 2019

Unbalance (Imbalance) is often defined as the unequal distribution of the weight of a rotor about its rotating centerline. A rotor can be balanced either in-place or in a balancing machine assuming unbalance is the issue and weight can be added or removed.  Modern balancing instruments will do the math for you. I originally learned […]
