Watts It All About

Watts It All About with Dan Helgerson

Welcome to a fluid power blog focusing on best practices, energy efficiency, and safety. The goal is to stimulate (not simulate) thinking, share knowledge, and promote professionalism. We welcome your comments as we share ideas, yours and mine.

Dan-HelgersonDan Helgerson, CFPAI, CFPS, sits on the International Fluid Power Society Board of Directors as treasurer and is the technical editor for Fluid Power Journal. He can be reached at dhelgerson@fluidpowerjournal.com.

What in the World Do Those Numbers in the ISO Cleanliness Code Mean?

We have been talking a lot about filtration here at the steel mill. My predecessor, Scott McLoughlin, had done a remarkable job in educating by example, demonstrating the need for good control of the fluids in our hydraulic and lubrication systems. He had helped stop the leaks and had added well thought-out filtration systems that […]

Outside the Box: Rethinking the Traditional Reservoir

This article will take a look at three alternatives to the traditional reservoir. First, we will look at a reservoir by Price Engineering that takes an entirely different approach to the use of the reservoir. Second, we will look at a Cylindrical Reservoir that was designed for a more efficient removal of contamination from the […]

Begin at the End

I was recently at a conference addressing the issue of efficiency in fluid power systems, specifically in hydraulics.  The conference was focused on existing systems rather than designing new ones.  The question was asked, “How do we know if an existing hydraulic system is efficient?”  Now, in all my years (I won’t say how many) […]

A New Spin On An Old Idea

I am going to go out on a limb to make a suggestion. Now, for me, this is not all that unusual. I have been described as someone who thinks “outside the box” and have been accused of not even remembering where the “box” is anymore. In fairness, this is not a brand-new idea, nor […]

Quads and the Fluid Power Systems Conference

When I first heard the word “quadrillion,” I thought it was a fictitious number like “gazillion” or “bazillion,” but it turns out to be a real number: 1015 or, if you will, a million times a billion. Now, I don’t know about you, but I have a hard time getting my mind around a number […]

So, You Say You Want to Make a Difference

One of the most rewarding things that ever happened to me in the field of fluid power was when a high school student spoke to me after a two-hour pneumatic training session for FIRST robotics mentors.  She told me that she had learned more about physics in those two hours than she had learned in […]

You Made the Mess; Now You Clean It Up!

Now, don’t laugh, but I once designed a hydraulic system for automatically cleaning horse stalls using the energy from the movement of the waiting horse. I won’t get into the details, but I was going to market it with the slogan, “You made the mess, now you clean it up!” When I think about the […]

Use It or Lose It

We are planning on making a system more efficient here at the steel mill. Two overdesigned hydraulic power units are each operating continuously 24/7. Each one would be capable of performing both jobs on its own, and we are thinking of consolidating the two into one system. There are some obvious environmental and energy benefits […]

I Know, It Hertz

I am pretty sure I am going to get some flack from what I am going to say in this article, but before you conclude that I don’t know what I am talking about, hear me out. It is not my intent to turn people against using one of the most excellent components for accurate control […]

Something Is Missing: Using Alternative Energy

There is something missing in my repertoire of fluid power components. Can you help me? In the Off-Highway 2010 edition of the Fluid Power Journal, Brian Hageman had an article on a new hydraulic pump. How many of you read it? Keep your hands up. Oh, you intended to read it but never got around […]
