Enter our network

This enewsletter you receive every month is just one of many ways we try to keep our pulse on the fluid power industry. Obviously, our flagship publications, our website and magazine, are most likely the most popular ways we stay in touch with our readers.

But we offer several other means of communication with users and makers of fluid power components and systems. If you're a user of Twitter, you can follow me and our publisher Michael Ference to stay up-to-date on the latest industry news. Or join our Facebook or LinkedIn pages and enter our social network.

In the meantime, enjoy reading your latest edition of Fluid Power Monthly!

Selection and use of bio-based hydraulic fluids
Vegetable seed oils belong to a chemical family called “natural esters.” These are simply oils that are extracted from vegetable seeds. Nearly all types of seeds contain oil. However only some types are present in sufficient quantities or possess characteristics needed to be commercially viable lubricant oils.

Oils extracted from plant seeds are considered triglycerides. Triglycerides containing high concentrations of oleic are well suited as hydraulic fluids because of oleic acid’s high oxidation resistance.

Silence is golden in ocean vessels
Until modern times, the oceans and seas had been a place of solitude and serenity. However, it is estimated that harmful ocean noise created by man, specifically from ships, has increased 10 times from 1950 to 1975 and is now rising at an even more alarming rate.

Minimizing the impact of built-in contamination
It is widely recognized that contamination creates problems in hydraulic systems. The explanation is straightforward — minimizing the gaps or clearances between moving parts improves efficiency and permits precise machine control. Particles compromise efficiency through abrasive wear and interfere with machine control when they become lodged in electrohydraulic valves.

Valve terminals raise machine performance and improve efficiency
Today, OEMs of all stripes strive to supply equipment that is reliable, efficient, and safe to operate — and ultimately cuts operating costs and boosts productivity. But this is nothing new. Valve terminals — modular platforms that combine pneumatic valves with electronic interfaces — were invented two decades ago to help meet these same needs. Their success speaks for itself. Festo, Hauppauge, N. Y., for instance, has installed more than 100,000 units worldwide, and acceptance continues at a brisk pace. But the latest versions bear little resemblance to original designs. Capabilities now include not only pneumatics and I/O, but also electric drives, motion control, safety functions, and built-in diagnostics. Here’s a closer look.

New Products

Digital pressure gauge
D1005PS digital pressure gauge from Ashcroft Inc. features a 1/2 in. tall, 4 1/2 digit LCD for easy reading and resolving of the ±0.5% FS accuracy. At the touch of a button, the display can be changed to read out in any of the nine pre-programmed units of measure. It also provides peak load indication, an optional backlit LCD and a rugged stainless steel sensor and inlet for use with a variety of wet or dry pressure media.

Hybrid pneumatic connector
Hybrid connector from Colder eliminates the need for multiple connections and simplifies the user interface between remote tools and a device. Featuring an easy-to-use twist latch to securely connect everything in one simple motion, technicians can quickly change or replace modular tools, umbilicals or hand pieces that require a combination of power, signal, air or fluids.

Tube fabrication
Hand-operated tube fabrication tools for small bore tube assembly from Parker Hannifin Corp. help to ensure leak-free, reliable systems. Packages include several tools. Heavy duty PTB tube benders for 1/4, 3/8, and 1/2 in. tubing sizes provide accurate, tight radius bends of up to 180° on soft copper, aluminum, brass, steel, and stainless steel tubing. PTC tube cutter for 1/8 to 1-1/8 in. stainless steel, steel, soft copper, and aluminum tubing features a lower profile swing radius of 41/4 in. Deburring tool for 3/16 to 1-1/2 in. O.D. tubing can be used on annealed steel, stainless steel, copper, or aluminum. Sawing vice with an integral hacksaw guide will accommodate tube, pipe, and hose from 3/16 O.D. to 2 in. O.D. Finally, inspection gauge is available in three sizes: 1/4, 3/8, and 1/2 in. (4, 6, and 8).

Return on Innovation: Making Individuals More Productive

The value proposition for equipping technical and creative professionals has drastically changed. The unprecedented combination of economic pressure and technological advancement has rewritten the rules of how to do more with less. Teams may forego new hires or do the same work with fewer staff, yet they can avail themselves to new tools and techniques. The challenge then becomes how to equip these valuable and fewer number of professionals to be more productive and innovative.
