The rotating machinery spin game – just a little bling

September 6, 2012 / 0 Comments / 156 / Industrial Applications

When you talk rotation in industrial equipment and machinery, the current solution proposed in most applications is a mechanical slip ring. However in the word mechanical you must read contacting, friction, heat, moisture susceptibility and maintenance.

If you’re a manufacturing person, this means downtime. If you read the websites of leading slip ring manufacturers, they want you to believe that the maintenance is gone, that the environmental factors don’t affect their system and they will run forever.

As you read further, you hear about the use of precious metals and new fiber components that eliminate the wear, corrosion and moisture effects on their systems. I will agree that these have helped improve their performance, but in no way eliminated the environmental issues – this is just their spin game. Ask any wind turbine operator and you will still hear of frequent slip ring problems that are driving way too much downtime.

You did notice the word PRECIOUS in their solution.

What is really precious is your maintenance dollars and your operating uptime. You’re only making money when the system is operating. Their new and improved technology is still old methods with the same issues, but in a shinier package. Please pardon my language, but you’ve probably heard the saying, “even if you gold plate a turd to make it look better, in the end all you still have is a turd”. I rest my case.

With PowerbyProxi’s Proxi-Ring, all of the environmental factors are truly neutralized. No contact, hermetically sealed up to IP68, rated for temperatures from -40 to 185⁰F. The system will transfer power and data over an air gap through any non-metallic material.

So, let’s save precious metals for jewelry and protect your precious operating uptime with a superior Proxi-Ring solution that keeps environmental conditions a subject for the local weather forecaster.

Can’t find the strike zone?

August 13, 2012 / 0 Comments / 150 / Industrial Applications

The sun is shining, there is a cool breeze blowing in from left field.  Yes, its Thursday afternoon and you’re at the businessman’s special watching your home town heroes play their arch rivals. As is the American baseball tradition, you have a hot dog in one hand, a cold beverage in the other, and a bag of peanuts rests on your lap just waiting to be cracked open.  On the field, however, things aren’t going so well.  The Ace is on the mound but he can’t seem to find the plate, he has walked three straight batters.  The fan behind you, an obvious fanatic, has an old transistor radio and is listening to the broadcast while watching the game and you hear the broadcaster say. “Joe is really having a pitch control problem today.”

Just then your phone buzzes, a new text message.  You put your beverage between your knees and look at the message.  You instantly realize that Joe is not the only person with a pitch control problem.  It’s “the farm”, turbine 7 is down due to lost connection on the mechanical slip ring on the pitch control system. They want you to come ASAP to climb the tower and get the turbine back up and running, as downtime equals lost revenue.   So much for those peanuts.

Now I am a guy that is fascinated with mechanical equipment and I admire the ingenuity and creativity that has led to such innovation, and this includes the mechanical slip ring and automotive ignition systems (yes they were mechanical at one time).  These mechanical designs were solutions to problems that haunted engineers for years and offered unique capability.  However, like points in the old mechanical ignition systems that has now been replaced by electrical fuel injection systems, the time for the mechanical slip ring needs to be in the past.

PowerbyProxi has worked with companies to develop an all-electric, non-contacting slip ring replacement called the Proxi-Ring.  This system that can be sealed to IP 69 level, deliver power from watts to kilowatts, and has no moving parts or frictional connection, allowing for the direct replacement of current mechanical slip rings with a high reliability, no maintenance solution.  So while you’re walking up the aisle with that unopened bag of peanuts, another company’s reliability team is ordering their second cold beverage as the reliever runs in from the bullpen.  See you at the ballpark.
