Fluid Power Symposium Comes to the Sunshine State

 

 

The University of Bath and the American Society of Mechanical Engineers (ASME) will hold their symposium on Fluid Power & Motion Control (FPMC 2013) at the Lido Beach Resort inSarasota,Florida October 6 to 9, 2013.The international conference provides a forum for leading‐edge activities in the field of hydraulics, pneumatics, and motion control technologies.

Generations of learning

Sometimes our staff is fortunate enough to have an intern work with us during the summer. This year we have Alexis Coffey, a senior at Ohio University, which is well known for its School of Journalism. In that school, Alexis is majoring in strategic communication — a cross between journalism and marketing. It’s been a great fit for all of us because she works on a variety of marketing projects when she’s not editing material for publication in the magazine or posting content to our website.

Accumulator bank breathes new life into core machine

A manufacturer of cast-aluminum automobile engine components called on Livingston & Haven to solve an operating problem with a core-blower machine that produced sand cores for molds — in this case, for cast intake manifolds.

A dual eccentric drive powered by hydraulic motors shakes pistachio trees, and hydraulic cylinders position collector assemblies to harvest pistachios from an entire tree in seconds.
Making tough hydraulics even tougher

 

Hydraulic systems are expected to perform in environments that would quickly render other forms of power transmission inoperable. But sometimes even the inherent ruggedness of hydraulics needs something extra.  Scrap yards, landfills, and some recycling centers often contain materials that can cut or abrade hose or damage piston rod surfaces. 

Virtual slip rings transmit power or signals across air gaps

Power Coupling Units (PCUs) can inductively transfer dc signals across air gaps to interface with solenoids, digital or analog sensors, switches, relays, and actuators on rotary indexing tables or moving equipment. Sensor Coupling Units (SCUs) take it a step further — transferring power and data simultaneously to rotating or moving sensors.

Return-line hose snakes its way to pumps

A big challenge to designing mobile equipment is finding a place to put all the hydraulic components. Locating cylinders is pretty straightforward, and valves and pumps need to be placed where they are accessible. But reservoirs are often placed anywhere on a machine that has a large enough void. This complicates routing of return lines because standard hydraulic hose may lack the flexibility to bend around obstacles.

Separator keeps air out of braking systems 1

Air or other gases entrapped in hydraulic circuits can cause erratic operation and lead to the formation of foam — which can be especially dangerous in braking systems. In a search for a reliable method to ensure that air would not get into the energy-assisted braking system of its machines, a manufacturer of mobile agricultural equipment found just that.

Cartridge valves add flexibility to excavators

Engcon AB, Strömsund, Sweden, is the world’s leading manufacturer of tilt rotators — attachments that are installed between an excavator’s boom and bucket to continuous 360° rotation and ±40° lateral pivoting of the bucket or other end tool. Engcon’s tilt rotators are equipped with a hydraulic motor for rotation and double-acting cylinders for optimized tilting force and even load distribution. Engcon´s tilt rotators can be used on most existing excavators and backhoe loaders within a weight range of 11⁄2 to 32 tons.

Quick couplings

Patented eSafe coupling combines high flow with low pressure drop in a durable compact envelope that has the dimensions of a standard coupling. Ergonomic easy-to-grip design and low connecting force allow convenient one-hand operation. Coupling vents downstream pressure before disconnection to eliminate hose whip and reduce noise. Complies with ISO 4414 and European EN 983 standards.
