Oilgear's PVM open-loop, axial piston pumps offer a compact, computer-optimized unit with multiple controls available. They come in three frame sizes, with multiple displacements available for each. They last longer, run under higher pressure, and have a higher resistance to contamination through its "hard on hard" rotating group, which uses hardened steel shoes on a hardened swashblock surface. Composite materials are used in the hydrodynamic bearing support on the cylinder barrel, meaning it can take higher temperatures. The pumps can be used with low-viscosity or other special fluids. They can be easily converted between right and left-hand-driven pumps, and they are still easy to install. They offer a rugged cylinder design; lubricated saddle bearing; cylinder mount in polymerous journal bearing for high performance in high-cyclic applications; sealed front bearings; SAE heavy-duty spline and keyed shafts; running speeds up to 3,600 rpm; a maximum pressure of 4,250 psi (293,1 bar), and theoretical maximum displacements from 0.66 in3/rev (10,8 ml/rev) to 7.94 in3/rev (130,2 ml/rev).
A middle school team from Rochester, Mich., has again nabbed the grand prize in the annual international Future City Competition, which drew students from 37 regions of the United States, as well as from England and China.
The word “smart” is becoming the dumbest word around. It has been applied to almost every device and system in our homes. In addition to smartphones and smart meters, we now hear about smart clothing and smart shoes, smart lights, smart homes, smart buildings, and every trendy city today has its smart city project. Just because it has a computer inside and is connected to the Web, does not mean it is smart.
Are you being paid enough? Do you want a better job? According to a recent survey Manpower released just before Engineers Week, employers and engineers don't see eye-to-eye about the state of US engineers' skills and experience.
