Energy Efficiency has become critical in hydraulic and pneumatic systems. Hydraulic and pneumatic producers are competing to reduce energy consumption in every area they can, from improved design in valves and pumps to right-sized components, pressure regulation, machine design, and advances in hydraulic fluids. Accumulated energy savings from these individual efforts can range from 15 percent to 35 percent. Taken together, these improvements can significantly drive down energy consumption.
Much of the gains have been driven by plants' needs to drive down energy consumption. Just a few short years ago, this wasn’t a major concern as they looked to hydraulic and pneumatic systems. Those days are gone. Now, energy consumption is a major concern. As well as cost, plants are also looking to become good environmental citizens by reducing their carbon footprints.
One of the approaches to reducing energy consumption is to reduce the size and space of the components. Integrated automation is another area that delivers energy savings, and variable speed drives are yet another move for saving energy.
Design News recently gathered experts in energy efficiency in hydraulic and pneumatic systems to discuss recent advances in energy efficiency. The Design News Webcast, "Energy Efficiency: Pneumatics/Hydraulics," brings together David Dornbach, engineering manager from Hydra Force; and Neal Hanson, product manager for industrial valves and electrohydraulics at Bosch Rexroth.
With regard to pneumatic systems, the single largest cost in any plant is - LEAKS. Walk through any plant, paying attention to your ears. You will hear, EVERYWHERE, the hiss of leaking compressed air. That sound is money being literally thrown away.
If one wants to save energy, reduce consumption, then the leaks must be found and fixed. Only after the plant floor stops hissing would optimizing the pneumatic system for efficiency make sense.
It's analogous to proper tire pressure and fuel economy. Keeping tires properly inflated is probably the simplest way to improve fuel economy, but is the most ignored.
The solution can be as easy as some pipe sealant paste or tape, or repairing/replacing a cracked hose. A single 1-mm air leak can cost $200 / year (based on calculations found on the net). One leak may not sound like much, but even a small plant will have multiple leaks. Just 5 is a $1000 per year, and that is if they're as small as 1 mm.
Sounds like the cost of a repair would pay for itself, TJ. As for sounds in plants, I've heard some complaints from baby boomer plant managers who say that the young engineers coming into the workforce rely too much on computer technology and they're not learning to tell the health of the plant by sound and vibration.
Truchard will be presented the award at the 2014 Golden Mousetrap Awards ceremony during the co-located events Pacific Design & Manufacturing, MD&M West, WestPack, PLASTEC West, Electronics West, ATX West, and AeroCon.
Robots that walk have come a long way from simple barebones walking machines or pairs of legs without an upper body and head. Much of the research these days focuses on making more humanoid robots. But they are not all created equal.
The IEEE Computer Society has named the top 10 trends for 2014. You can expect the convergence of cloud computing and mobile devices, advances in health care data and devices, as well as privacy issues in social media to make the headlines. And 3D printing came out of nowhere to make a big splash.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This discussion will examine what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
