Measurement Mode: 9-12-3 The Classic Three-Point Method

December 5, 2023

Measurement points are recorded at three fixed clock positions: 9, 12, and 3 o’clock. This is the classic three-point method which can be used in most cases. Below are some applications where this mode is preferred: Vertically-oriented alignments: When performing an alignment on a vertical machine the automatic inclinometer used to determine the shaft’s rotational […]

Types of Balancing Machines: Soft Bearing vs. Hard Bearing

November 28, 2023

There are two primary types of balancing machines; a Soft Bearing Machine and a Hard Bearing Machine.  Both types have advantages and disadvantages. Here are the differences: Soft Bearing Balancer A soft bearing balancer allows the rotor ends to move freely in the horizontal direction of the balancing stand.  This type of balancer allows the rotor to turn […]

Key Features for a Vibration Analyst

November 21, 2023

When monitoring the vibration data of a machine, an analyst will want to look at the Time Waveform (TWF) and the Frequency Spectrum or FFT (Fast Fourier Transform) output, as shown below. These two example plots are very useful for determining obvious failure modes, such as, an imbalance with a high amplitude value of Overall […]

Using ANSI Shaft Alignment Tolerances to help solve base-bound and bolt-bound situations

November 14, 2023

Use ANSI Shaft Alignment Tolerances to help solve base-bound and bolt-bound situations. If a base- or bolt-bound situation presents itself during an alignment, take advantage of the outer limits of the tolerance envelope to help overcome the problem. It may be possible to optimally position the machine to meet the minimal ANSI tolerances and eliminate […]

Give Your Machines the Correct Prerequisites

October 17, 2023

Within the industry, maintenance of machinery and plants is routine work. However, not everyone knows how to minimize future costs and risks for downtime from the start. Although it is so apparent! Increased sustainability and reduced energy consumption Everywhere in our society, machines are used for producing varying items, process materials, pump fluids, etc. These […]

About Lines of Resolution for Vibration Analysis

October 10, 2023

Lines of resolution (LOR) describes the number of lines of information that appear in the spectrum (FFT) acquired by the vibration data collector. LOR can be calculated by dividing the overall frequency range collected (Fmax) by the number of lines selected. LOR represents the amount of detail in the collected data. Without sufficient detail in […]

Have You Ever Used An Aluminum Can To Shim Your Motor?

October 3, 2023

When the beverage industry started to market its products in aluminum cans, a new by-product for industrial maintenance was created— soda and beer cans were sometimes used as shimming material for electric motors. Aluminum cans were flattened out and a slot cut into them to allow the shim to fit under the foot of the […]

Torque: Why, How, and Where – Part 2 The How and Where

September 26, 2023

In my previous blog Torque: Why, How, and Where, we talked about the why. Now we need to achieve a correct clamping force, and so we will discuss how to get there. Here are the normal ways of torquing hardware, in order from the least accurate to the most accurate. Impacting Hand tightening Using a […]

How to Deal With Thermal Growth

September 19, 2023

All rotating machinery is subjected to thermal exposure. The machines will react differently depending on temperature and material, either by expanding or shrinking. And that is a fact. Thermal growth is a serious thing when you think about it. All rotating machinery is installed in trains. Trains mean there is a driver, the motor, and […]

Myths and Truths about Balancing

August 22, 2023

MYTH: “1x RPM is always caused by unbalance.” TRUTH: Unbalance always causes vibration at 1x RPM.  However, 1 x RPM is not always caused by unbalance.  Many other problems can exhibit vibration at this frequency.  Examples are Misalignment, Bent shaft, bowed shaft, cracked shaft, eccentricity, open rotor bars in the motor, rubs, looseness, belt issues, […]

Importance of Shaft Alignment: Parallel & Angular Pump Alignment

August 15, 2023

Well-lubricated and properly aligned machinery are integral to the smooth running and continual functioning of your equipment and overall facility. Shaft alignment of rotating equipment is particularly important, as the unnecessary stress produced by misalignment will cause unexpected and costly downtime. Poor vertical and horizontal pump alignment damages your equipment’s seals and couplings, which have been proven […]
