We have all dropped off our vehicle at a mechanic for an oil change and left with a bill 2 times the initial cost and have idea what we actual spent our money on. The same can be said for motor repair, do you know what the motor failure was? Did they explain what could have caused this failure?
When you start a compare and contrast with Predictive Maintenance and the Internet of Things within the industrial maintenance world; you may have some people scratch their head and say, “are they not the same thing?”. Well, the easy answer is a simple answer of yes and no. Yes, they are both moving towards a new way of understanding maintenance and maintenance needs. No, they are not the same because different tools and technologies are being used to assess equipment and assets.
With springtime coming to an end it’s not too late to get some last-minute spring cleaning done in your storerooms. So here are three ideas for cleaning up and consolidating your spare motor inventory.
In today’s day and age you can put any motor part or catalog number into an internet search engine and come back with numerous places to purchase the unit. Being that the maintenance world tends to be on the reactive side of purchasing this makes it easy to get your hand on a product right away. Is this always the best way to purchase a motor? Is buying from the company you buy your bearings from a good idea? Maybe you are getting a chance to buy directly from the manufacturer? Or should you purchase from an EASA shop (Electrical Apparatus Repair Association) that is repairing your motors? All of these options have pro and cons when it comes to buying.
There are many benefits to ultrasound, but before discussing them it is important understand what it is and how it works. Ultrasound can be defined as a detection method used to locate leaks such as; pressure, gas and vacuum. It can also be used for bearing, steam traps, and mechanical inspections. This is done by locating and trending decibel (dB) levels caused by friction.
Every day industrial machinery is being taken offline and removed for repair, and after the work is complete reinstalled and put back into service. From the moment the decision is made to shut the unit down until power is reapplied there are a lot of decisions to be made, and in cases of unplanned downtime these decisions are usually made during some understandably stressful circumstances. Some facilities are fortunate enough to have millwrights on staff who are completely capable of safely removing electric motors and reinstalling them using best practices, but more and more we see plants that are short staffed and simply do not have the manpower to handle this aspect of the job themselves.
I am often told “I want that motor varnish dipped too”, but is re-dipping a reconditioned motor really good for the motor? Using proper repair practices motors can be reconditioned and repaired many, many times. Putting varnish over varnish continually is not always in the best interest for that motor in the long term.
Many companies have spare electric motors in their warehouse in the event of a critical motor failure. Many times this can be an intelligent decision, allowing for quick change out in the event of a failure (or pending failure) or during a scheduled outage or shutdown.
This is a (9) nine minute segment of a larger (1) one hour presentation given by Mark Hatfield, Chief Executive Officer of HECO - All Systems Go at the 2017 Reliability Process & Maintenance Symposium.
This covers a variety of aspects of selecting and managing electric motor repairs. From developing an electric motor repair specification, qualifying and validating repair vendors, developing condition and assessment reports, final report standards, and finally implementing fixed pricing for motor repairs through a pricing matrix.
It’s relatively common to walk into an industrial plant or facility and find that they are stuck in a reactive state of maintenance. Most of these facilities have a desire to change but just don’t know how to get there. The first step is to understand some of the advantages and disadvantages of reactive maintenance.
