Gearing up for
It's been a busy few weeks as we've been caught up in "show fever"
over here at Hydraulics & Pneumatics. I flew south to Atlanta for
AgConnect last month, and if IFPE is on your horizon, be sure to check
our website next week for even more IFPE coverage. We've got you covered with an
exhibitors' list, show map, education schedules, and products being
highlighted at the event.
In the meantime, read on about electropneumatics, hydraulics in the
shipyard, pneumatics in food processing, and hydraulics for ag

Protection from environment is key to lift
Shipbuilding can wreak havoc on hydraulic systems. It occurs ocean
side, so saltwater spray poses a daily threat to the corrosion
resistance of piston rods in hydraulic cylinders. But a greater threat
comes from spatter and other debris generated by welding operations.
Welding occurs throughout the construction of ships, and welders seldom
have the luxury of standing on solid ground. Instead, they may be
perched atop a telescoping lift. These lifts are also used for other
assembly and painting, but welding poses the greatest threat to
hydraulic systems because the debris can cause premature failure of
cylinders and hoses. And even if it doesn’t damage the cylinder
itself, debris that adheres to a moist piston rod can quickly accumulate
inside the hydraulic system to cause component malfunctions.
Boosting engine performance with
As requirements for commercial vehicles get more demanding, the
diesel engine is rapidly becoming a far more sophisticated platform.
Requirements driving this advance include emissions regulations, fuel
efficiency standards, and higher user expectations for drivability and
reliability. Meeting these demands requires control systems and
associated actuators able to maximize the performance of specific
Multi-function actuators position food
Shelf life is the key to success for groceries — particularly for
ready-to-eat prepared foods. Obviously, the packaging of these products
plays a major role in their shelf life. Orics Industries Inc.,
Farmingdale, N.Y., a company that engineers automatic packaging systems,
supports extended shelf life for prepared foods with its
modified-atmosphere packaging (MAP) technology.
New design calls for innovative
There’s really only one option when a machine series comes to the
end of its life cycle, and the competition starts gaining market share.
You must develop a brand new series with the latest technology,
impressive user benefits, and an overall design that leaves other
machines in the dust.
Hydro-pneumatic piston accumulators from Parker Hannifin Corp.,
provide long-term effectiveness in critical wind turbine applications
through significantly lower maintenance and servicing costs. They are
avaialble in 1.5- to 20-in. bore sizes with capacities up to 200 gal.
All are designed to fit specific wind turbine applications. They have
less frequent service intervals and maintenance requirements compared to
bladder or diaphragm units, so provide a lower total cost of ownership,
saving substantial operating costs over the life of the turbine. Because
of their small seal, they fail gradually and allow plenty of time for
Pressure transmitters, switches
The 800/810 series of electronic indicating pressure
transmitters/switches from Noshok provides continuous pressure
monitoring and allows programming of set points without applying
pressure. The 800 series is available in stainless steel and 810 series
comes in black anodized aluminum. They are rated for pressures from 14.5
to 9999 psi. Three switching output options are available: two switching
outputs; one switching output and one analog output (4-20 mA or 0-10 V);
or two switching outputs and one analog output (4...20 mA).
FasTest TwistMate MIT (internal) and MET (external) connectors come
in stainless steel and provide a seal design that delivers a leak-tight
connection to threaded pipe — quickly and without the use of wrenches
and thread sealants. Twist-to-connect and pressure-assisted,
grip-and-seal design allows fast, safe and repeatable threaded
connections, eliminating thread wear and damage common to traditional
connectors. They are twisted to finger-tight onto the mating thread
profile. When system is pressurized with air or hydraulic pressure, main
seal is pressed against test piece and connector will automatically
seal. The internal piston action maintains the seal with minimum
pressure. They are rated for pressures up to 10,000 psi. Sizes range
from 1/8 to 3 inches NPT, and connectors are also available in BSPP,
BSPT, SAE, and Metric specifications.
Illuminate the World: Energy Efficiency Summit 2011
February 17th & 18th, 2011
Many issues surround the adoption of standards and
testing requirements for energy efficient lighting. Illuminate the
World: Energy Efficiency Summit 2011 will address the changing landscape
of ENERGY STAR certification for lighting products, present-day and
future standards, testing procedures, technological advances, and market
dynamics. CSA, a global leader in testing and certification for more
than 85 years, has partnered with Energy Efficiency & Technology
magazine to help educate lighting manufacturers on compliance with
energy efficiency rules and regulations. This exciting new event will
provide a comprehensive conference to educate lighting professionals and
increase their awareness of global lighting standards and usage.
