FLUID POWER: Two new KNF swing-piston pumps introduce ideal solutions to transfer, evacuate, or compress air or inert gas and deliver oil-free performance without any potential risk of contamination. The new models include a compact and efficient 3.3 l/m micro pump and a 25 l/m mid-size version with both providing vacuum or pressure capabilities.Their addition broadens the KNF swing-piston product line to include pumps offering flow ranges of 3.3 l/m, 9 l/m, 18 l/m, 25 l/m, 50 l/m and 78 l/m with vacuums to 27.6 inch Hg and pressures up to 100 psig., depending on type.
Among features, the sealing lip between the cylinder and wall has been designed to minimize frictional loss and promote a long service life, while running quietly with minimal vibration. Pumps can operate in any position and are supplied ready for installation.
All versions can be specified with ac motors, brush-commutated dc motors or brushless dc motors (with brushless types engineered for longer service life and allowing for pinpoint speed control).
These pumps can be used for a wide range of OEM applications requiring reliable pneumatics. Standard versions can be customized to meet particular OEM requirements.
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.
