Implementing a Hybrid Model to Monitor Machinery Vibration

Monitoring machinery vibration can use many tools and models, including a hybrid model. Some of the monitoring tools available today include: Portable vibration data collectors and analyzers.  Short-term surveillance vibration data collectors and analyzers (which can be installed temporarily). Embedded sensors mounted to equipment which can monitor vibration, temperatures, and other inputs. Permanently mounted accelerometers…

A Handy Guide to Balancing Rotating Machinery

icon of a fan with a spot indicating a balancing weight.

Balancing rotating machinery is mostly math, with a bit of common sense and experience thrown in. The math is constant, so here are some tips to help with the common sense and experience part. Preparing to balance Inspect before you balance I once balanced a fan by pulling an air filter out of the fan…

Using a Strobe Light to Verify RPM

Knowing the correct rotational speed is critical when performing machinery diagnostics. A strobe light can be an excellent tool for determining speed. Look for a unique mark such as a keyway, piece of tape, etc. to use as a reference. You will adjust the flash rate of the strobe light until you only see one…

What is Machine Misalignment Costing You?

We often hear from clients that machine misalignment is a costly and inconvenient problem. But, just how costly is it? It is far more expensive than most people realize, especially when you take today’s supply chain concerns into account. Between downtime, equipment damages, overtime for repairs, and supply chain interruptions, a fairly minor amount of misalignment…

Adding Process Points to a Data Collection Route

Sometimes other data can influence analysis when running your regular routes. This data can range from discharge pressure on pump to slide valve position on a chiller or maybe just bearing temperature just to name a few. With the Falcon and Nest this type of data can be collected and even trended in the Nest.…

Generating Global and Special Reports in the NEST

Once you have moved your data back into the Nest, after a Route has been collected, you may want to provide a report or reports to different parts of an organization. The Nest has several ways of generating a couple different types of custom reports. For your discussion we will focus on a global report…

How to Reorder Points in the NEST

Setting up routes is a very easy process in the ONEPROD NEST software and allows you to move machines into any order to allow for expeditious data collection. However, sometimes points need to be rearranged within the machine. Take the gearbox below for example.  Due to its size you don’t want to have to walk…

RESOURCES

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

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,…

Precision Maintenance in Data Centers

  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…

Adding Machines to an Existing Route in Your Nest Software.

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…

Seal Failures Caused by Base Issues

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

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

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…
