The need for lower weight, size and costs mean that mobile machinery often sets the stage for power density improvements in fluid power. All hydraulic machinery should be similar in scope and design, one would think. After all, the point of fluid power is to transmit force. Why should any given mobile machine be vastly […]
How is electronic control of fluid power evolving?
Electrohydraulic or hydroelectric? It’s odd how similar those two compound words are, yet they’re obviously entirely different in meaning. Hydroelectric refers to the production of electricity by way of converting the potential kinetic energy found in conjoined bodies of water of varying height, into electrical energy used by everyone and their hamster. Electrohydraulic is the […]
Why are accumulators so scary?
By Josh Cosford Compared to many of you reading this, I am young in this industry, and as such, my fluid power career is sophomoric at best. Depending on your perspective, I am lucky (cursed) enough to experience the slow movement of time. Time does not fly for me, so the year 2006 seems a […]
2017 Canadian Fluid Power Association Annual General Meeting wrap-up
The Canadian Fluid Power Association strives to further the fluid power industry, and during 51 weeks of the year, we focus on education, market insight, fluid power careers and industry cooperation. But over a few days in the late spring, we mix it up with our peers in a mosaic of business, networking and straight […]
What is pressure compensation?
You’ve been around hydraulics a while, haven’t you? With that in mind, you probably take some things for granted. There is plenty of jargon in our industry, and it isn’t learned overnight. However, if you were like me, the term pressure compensation was difficult to grasp early in your hydraulic career. If you still don’t […]
What makes a quality hydraulic component?
If you’ve been around the hydraulic world for a while, you’ll have noticed there is a price discrepancy between various component manufacturers. Whether there is a correlation between price and quality is a discussion unto itself, but regardless, you can’t argue the price range is vast. Let’s assume for this missive that higher priced components […]
9 dumb mistakes people make when designing fluid power systems
Sometimes dumb is relative. Was Einstein dumb because he brushed off quantum entanglement as “spooky action at a distance?” He was wrong, of course, because two entangled subatomic particles can travel away from each other in opposite directions for a million years, and when one finally hits something, the other is immediately affected as well. […]
What is electronic control in fluid power?
Hydraulic valves operate most commonly in one of three ways; mechanical/manual control, pilot control or electric control. Mechanical control involves something physical pushing on the valve, such as with a roller or cam, which itself shifts the spool or poppet. Manual control was long the king of valve control, especially with mobile hydraulics; they’re inexpensive […]
Where do you locate fluid power components?
We at Fluid Power World write many articles about fluid power components, but less often do we write about where these components are located in a system. You can find in our pages/on our websites what a transducer is, what a relief valve is and what a flow control is, but you will find fewer […]
He uses a relief valve as a flow control. You won’t believe what happens next
I’ll admit, I’ve fallen prey to one of these “you won’t believe what happens next” taglines floating around Facebook and other social media sites. If you’ve never seen them, hopefully mine suckered you in. Because you won’t believe what happens next. I’ve actually seen a relief valve used in place of a flow control, and […]
