3 Types of Mechanical Looseness: What You Need to Know

|

By on October 29, 2019

Mechanical looseness is a common diagnosis in vibration analysis. You will certainly run into it when you are monitoring your machines if you haven’t already. However, did you know that there are three different types of mechanical looseness? Knowing which type of mechanical looseness you are dealing with is essential to providing the correct solution […]

Vibration Analysis: Where to Start

| | | |

By on September 30, 2019

  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 […]

How to Differentiate Unbalance and Looseness on the Spectrum

| | |

By on September 20, 2019

  What is the difference between looseness and unbalance? They have very similar spectrums with different influencers. One can even impact the other in some situations. That similarity can impact your ability to balance a machine expeditiously in the field. For clarity of this discussion we will limit it to Type A and B mechanical […]

Finding Unbalance and Misalignment on a Spectrum

| | |

By on July 22, 2019

  Unbalance and misalignment are problems that need to be addressed as soon as possible, but before you can begin to fix them, first you need to know how to find them on a spectrum. We will go over this below. For example, with a fan, unbalance appears on the spectrum as a higher than […]

I read that Albert Einstein once said, “I don’t need to know everything, I just need to know where to find it when I need it.” If one did some research, that may not necessarily be true. However, if a question comes up, it’s always helpful to have resources to refer to. When it comes […]

Proper RPM Set Up with the OneProd Falcon

| | |

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, […]

By on April 17, 2019

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 […]

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 […]

By on December 13, 2018

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 […]

Mechanical Looseness Identification

| | | | |

By on November 2, 2018

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 […]

Vibration Sensor Mounting Tips

| | |

By on September 13, 2018

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 […]

The Soft Foot Primer (Part 2) Vibration and Alignment Problems Related to Soft Foot

| | | | |

By on February 26, 2018

Most industrial maintenance mechanics who are involved with precision shaft alignment are familiar with the phenomenon of soft foot.  From an alignment standpoint, soft foot causes: Changes in alignment values, between when the hold down bolts are loose, and when they are tight. Non-repeatability in alignment measurements, especially if the bolts are not tightened in […]
