Straightforward Stern Tube Bearing Carrier Alignment with Easy-Laser® E950-B System

September 18, 2018

We just returned from performing a stern tube bearing carrier alignment on a large container vessel currently in construction at a leading US shipyard. The one-meter diameter bearing carriers needed to be set to specific tolerances with respect to an established datum line along the longitudinal axis of the ship. Historically, this was accomplished using […]

How Ugly is a Plant Shutdown due to Machinery Failure?

September 11, 2018

When the breakdown/repair cycle becomes routine, you can bet money is being wasted. The psychology of manufacturing (if we can call it that) is very much overlooked. Q: What if it was a personal affront to everyone in the plant, management, production and maintenance, for a machine to break down? Seriously. What if everyone viewed […]

A Simple Procedure for Identifying Turbo Leaks in Diesel Engines with SDT TIGHTChecker Saves Millions

September 4, 2018

The diesel engine is the heart of heavy construction equipment and replacement costs are in the millions. Ingress of dust due to leaky air intake systems shreds components in short order.  The SDT TIGHTChecker quickly and easily pinpoints leaks in the air intake system. Dust is no friend to a diesel engine. But when the integrity […]

7 Habits of a Highly Effective Vibration Analyst

August 28, 2018

Knows how to use the software package they have. Knows how to use the hardware they have. Knows where to place the vibration sensor to ensure good data. Knows how to recognize bad data. Knows what to look for while collecting data besides just the vibration sensor. Knows how and to whom to report their […]

How to Avoid Failure of Centrifugal Pumps

August 21, 2018

Centrifugal pumps have a specific design point at which they operate most efficiently. This sweet spot is known as the BEP (Best Operating Point) which provides the design engineer with the required flow and pressure while also providing the best efficiency. If the pump has been specified incorrectly or is placed into a system which […]

Ultrasonic Leak Detection – Using the Sensitivity Adjustment

August 14, 2018

Guest Tip by Bob Dunn from I&E Central, Inc. In some environments, reflected sounds can make it difficult to locate a leak.  If you are in a confined area (a smaller room, or beneath/inside a machine), the leak can seem to be almost anywhere.  A good solution is to adjust the sensitivity downward.  Ultrasonic sounds will […]

6 Key Reasons to Use an Online Vibration Monitoring System

August 7, 2018

There are many different reasons to consider and implement an online vibration system. Some of the key reasons are: The equipment is critical to production. The equipment has a long repair time. The parts for the equipment have a long lead time. The equipment is not easy to access. The equipment is in a remote […]

8 Reasons Why Employees Don’t Ask for Training

July 31, 2018

Reposted from People and Processes, written by Jeff Shiver CMRP, CPMM, CRL Do you find yourself wondering why your employees haven’t taken the initiative and approached you for additional training? Well, they must not want the extra training, right? Wrong! Sometimes, employees do want training, but they just don’t ask. Here’s why: 1. THEY HAVE FEAR OF […]

Maintenance Tip on Pipe Stress

July 24, 2018

Guest Post by Ricky Smith, CRL, CMRP, CMRT Pipe stress is caused by misalignment of the mating surfaces of two pipe flanges creating abnormal internal stress of pump bearings, seals, motor bearings, couplings, and can possibly change the displacement of a pump. General Rules which must be followed by maintenance personnel and contractors: (if you truly want to stop a long term pump problem) Pipe flanges attached to pumps must be aligned where the gap does not exceed the thickness of two gaskets or tolerance established by your company’s engineering standards. Pipe flange bolts must drop in without assistance. Cable pullers, come-a-longs, or long bars should not be used […]

How Bearing Defects Show Up

July 17, 2018

This blog post concerns rolling element bearings and not journal bearings. When a rolling element bearing begins to deteriorate the damage usually manifests itself in one of the races (either inner or outer) followed by the rolling element, and finally the cage.  When the races begin to have defects these tend to excite the natural […]

When is it Okay to Over-Lubricate your Bearing?

July 10, 2018

Question: When is it OK to over-lubricate your bearing? Answer: NEVER!!!!, (almost) the exception is when high vibration exists. If you attended the SDT/LUDECA Acoustic Lubrication Workshops then you now understand grease as a lubricating mechanism. You understand that the Churning Phase of the lubrication task is inevitable, and long-term, detrimental to the health of […]

5 Reasons You Should Certify Your Technicians

July 3, 2018

Reposted from People and Processes, written by Jeff Shiver CMRP, CPMM, CRL The CMRT exam is the leading credentialing program by the Society for Maintenance & Reliability Professionals (SMRP) for the knowledge, skills and abilities of maintenance and reliability technicians. The CMRT exam tests competency and knowledge of specific tasks within 4 domains: Maintenance Practices, Preventative […]

A Difficult Alignment Made Easy

June 28, 2018

Guest Post by Bob Dunn from I&E Central, Inc. I had the opportunity use the Easy-Laser XT440 to assist a customer aligning a machine that had perpetually given them problems, with bearings always running hot. They had recently aligned the machine with dial indicators, but when we checked, it was off by .007, and this on […]

Are you Listening to the Heartbeat of your Equipment?

June 28, 2018

In most cases, when equipment is in failure mode, it begins to make sounds that are not commonly heard during normal operation conditions. Once this sound is heard a defect (at least one) is already present in the equipment. Using our vibration tools can assist in detecting the defect before that sound is heard with […]

3 Practical Tips for Ultrasound Leak Detection

June 28, 2018

There are 3 techniques that can facilitate your work in the field: the shielding technique, the covering technique and reflection management. 1. Shielding technique This technique greatly reduces the influence of interfering leaks. It consists in using a piece of cardboard or foam(*)… to create a barrier between the “parasitic” leak noise and the location […]

May 29, 2018

Guest post by John Lambert at Benchmark PDM Recently I have been seeing the P to F interval curve popping up a lot on my LinkedIn feed and in articles that I have read. It was a concept that I was first introduced to when I was implementing Reliability Centered Maintenance into the Engineering and Maintenance […]

6 Signs your Lubrication Program is on Track

May 22, 2018

1. A Change in the Quantity of Grease Consumed Maintenance departments track their grease consumption to monitor and control costs. A change in consumption is a sure sign that your lubrication program is on the right track. Most organizations are guilty of over-lubricating. Expect lower grease consumption as your program matures. Bad procedures lead to […]

How Long Does it Take to do a Machinery Alignment ?

May 15, 2018

In the 35+ years of experience that LUDECA has in shaft alignment, we have been asked this question many times. How long does it take to do an alignment?

What it Takes to be Successful at Balancing

May 8, 2018

Just what does it take to be successful at balancing?  Let’s start with some basics. First you need to have an understanding of the balancing process, next nomenclature: is it unbalance, imbalance, out of balance, or what? Use a consistent description and stick with it. Next, think about what the source of unbalance could be: […]
