Your Reliability Engineering Professional Development Site
A listing in reverse chronological order of these article series:
When a control valve or manual valve is shut fast in a full pipeline of moving liquid, the liquid comes to a sudden stop. If the pipe suddenly starts banging and thrashing about you can be sure a water hammer was created. [Read more…]
First things first, let’s get something straight, I am not an internet marketing genius. I do however talk with dozens of folks like myself who have active websites, write regular blog posts and enjoy interacting with family, friends and even customers via social media.
As a result like everyone else I have my list of pet peeves, the things that on their own may not send me over the top but put a few of them together and you will find me talking to the computer screen or my cell phone in a language not intended for young audiences. [Read more…]
Another great method of becoming overwhelmed with work as a Maintenance Professional is to fill our day full of meetings. Worse, those meetings usually do not provide any value to you, nor do you have any inputs into the meeting.
We all know the meetings we dread going to, not because they are long, or the people in them, but because we know that it is a complete waste of time and is preventing you from accomplishing important maintenance & reliability tasks.
Next to emails, meetings are one of the most common complaints as a time waster that prevents the department and business from moving forward. Some meetings are required, and some need you the Maintenance Professional, but not all.
Throughout the rest of the article, we will cover how the Maintenance Professional can identify, evaluate and end those ineffective meetings. [Read more…]
This true story could have been a lot worse. A NB100 (4”) flanged plug valve was removed from a 98% sulphuric acid tank nozzle and returned to the supplier. When the valve was opened for inspection at the supplier’s workshop acid was sprayed over the repairman’s legs.
If 98% sulphuric acid lands on skin it immediately boils out the moisture in the skin and burns it. A review of the incident was conducted to learn from the accident and to put corrective measures into place. [Read more…]
I’m participating on a conference call with a number of companies who made the commitment to begin a reliability journey. Each have drafted a 3 year vision that includes quarterly goals or milestones they worked to achieve and I’m impressed that the first company to present appears to be on goal or even ahead of their target.
“We had a goal this quarter to certify 60 people across our three sites and in our first month 28 people have taken the exam and if all goes as expected we should have at least 20 of those pass the exam. Next month we have over 30 people signed up so I think we are well on our way.” [Read more…]
A common complaint I hear and experience is as a maintenance professional, our inbox has exploded and grown rapidly with all the daily activities in a plant. All the emails are perceived to be important, but in reality, they are mostly urgent, or not important and not urgent.
Take a moment and think about how much time you spend reviewing and answer emails. Even those emails that do not need a response, need time to review and move or delete. I am guessing you spend at least an hour a day dealing with email. Now think about what you can do with that hour… you could move the department forward and achieve the department and business goals.
Thankfully there are 6 steps you can implement to reduce the number of emails you receive and reduce the amount of time it takes to manage the remaining email. [Read more…]
This article explains the operation of peristaltic (hose) pumps and gives twelve points to be aware of when using them. [Read more…]
So I got to wondering today, is it just me or are there way too many pets on planes these days?
And, just so I can maybe avoid 1 or 2 hate replies I am a pet owner. I have always loved all of my pets, I have spoiled them on occasion and we treat them like family. I love coming home the unglued excitement of a wagging tail powerful enough to take anything not nailed down off the closest table but I have to wonder how much our pets really enjoy being dragged onto a flying tin can captured in close quarters for hours at a time only to have the doors opened to an environment where their owners speed walk to the nearest rest room but poor Jake still isn’t allowed to relieve himself?

You are running from one meeting to another, to a breakdown, to the storeroom and at the end of the day you stop and think. What did I really get done today? The day was busy, but did you accomplish what you wanted to or will make a difference in the long run?
The organization needs to focus on effective maintenance, and as a maintenance professional you need to be effective with your time. Only if you are effective with your time, can you drive the organization and the maintenance program forward. Being a maintenance professional it can be difficult to discern between the urgent and important and it is easy to get caught up in the rat race.
This will be a 4-part series on how a maintenance professional can free up time in their day and be more effective in driving their goals forward. [Read more…]
This article presents a basic explanation of electric motor construction and operation along with eleven problems that can be encountered with their use.
Most electric motors in industrial equipment are three phase alternating current induction motors. Induction is the creation of an electric current across a gap. Two types of induction motors are commonly used: squirrel-cage and wound-rotor. The names come from the way they are built. [Read more…]
The finger pointing in Flint Michigan has already begun and it’s likely to reach and cross several levels of Michigan’s government. We have developed a society where it has become more important to find out who is to blame, than it is to find out what happened and how we can be sure it never happens again.
Regardless of what you may have read in the papers or seen on the news the effects of lead poisoning are real. Chronic lead poisoning over time like one would expect from a contaminated water source results in damage to every part of the human body and lasts a lifetime. [Read more…]
Imagine being asked to discuss a breakdown during a production meeting. Only you are not aware of a breakdown, but production is claiming there was one and it could have been prevented by some Preventative Maintenance. You ask what equipment the breakdown was on and check the records. The records show there was a minor corrective action on the equipment last night, but not a breakdown.
After some discussion, the production manager explains that there was a leak, and the line had to be stopped to repair the leak. You know that a leak is not a breakdown, and will not impact production. The production manager saw a leak and assumed it was a breakdown. The end result was an unplanned outage lasting 30 minutes.

In this article on pulse jet bag house dust collectors we cover twelve factors spanning their design and operation.
A bag house dust collector is used to separate dust from a dust-contaminated gas stream. The gas is filtered through bags made of fabric. The fabric traps and filters out the dust while the cleaned gas passes through. The fabric consists of either woven or intertwined (felted) fibres. The bag fibre is selected for its ability to give a long working life within the internal environment of the dust collector. [Read more…]
The process to design and deliver a reliable product involves identifying risks. Taking action to understand or mitigate those risks involves much of the day to day work of reliability engineering.
Taking action to set expectations and improve decisions involves change. Change of understanding, change of specifications, change of expectations, change of designs, processes, and results.
It is the changes, big and small, that occur that achieve the desired results for the customer and organization.
You also know that not every suggestion is greeted warmly. Not every proposal is funded. Not every recommendation is accepted. [Read more…]
Like it or not we live in a society where we like to keep score. The score provides feedback; it gives those who are not involved information on the progress or success of those who are involved. The score can be delivered in an endless number of formats, the price of your company stock, net profits, unit cost of product, overall equipment effectiveness, or percent emergency/demand maintenance. In the world of Reliability Centered Maintenance RCM Guru Jack Nicholas gathered a team of experts several years ago to develop the RCM Scorecard. The result of this effort was a comprehensive tool that evaluated Key Performance Indicators at various periods before and during an RCM Project. [Read more…]
