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 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 firstname.lastname@example.org.
We are in the Fluid Power business. We are convinced that Fluid Power is the right choice for transferring energy in this specific application. We know that we can replace some electric motors with hydraulic motors and be more efficient. So, why do we use electric motors for our off line filtering and temperature control […]
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 […]
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 […]
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) […]
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 […]
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 […]
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 […]
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 […]
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 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 […]
