, gaskets, O-rings, valves, bearings, vanes, springs, and other items. Wear and tear on the parts may require a total rebuild and, with it, the need to keep spare pumps on hand. Life expectancy. Because compressed-air-driven pumps have few moving parts, they tend to last a long time. Standard pump

Pump Up the Pixels Pump up the pixels
of a CMOS wafer can be one-third the cost of a similar CCD wafer because CMOS sensors can be manufactured on just about any standard silicon production line. CMOS sensors consume little power. CCDs, on the other hand, can consume up to 100 times as much power as an equivalent CMOS sensor. They also

CAD and CAM help shop pump out micromedical parts
CAD and CAM software from Delcam Inc. of Windsor, Canada (delcam.com), help a medical manufacturer pump out hundreds of thousands of tiny pacing leads every month. An example of a molded silicone connector from Oscor is placed on a penny to show the small sizes of parts the company can make

Optimizing Existing Designs through Cost-Effective Simulation - How CFD Simulation Provides Pump Manufacturers with a Virtual Test Facility
The chopper pump is a centrifugal pump that utilizes. a chopping action between the impeller and suction. plate. These pumps were originally designed in the. 1960s for use in the local dairy industry to transport manure. to and from storage tanks. Since then this design has been continually refi

Power Units
Sometimes the complexity and magnitude of a job suggest that a system of separate hydraulic components would be difficult to put into action. In such a case, a power unit consisting of a reservoir, pump, drive motor, filter, heat exchanger, and basic system valving could be used. The pump includes

BASICS OF DESIGN ENGINEERING: FLUID POWER
easier to install and maintain, costs less, and performs better. First of all, tube fittings are designed not to leak, even under rugged operating conditions because they have mechanical, metal-to-metal seals. Tightening fitting nuts coldswages ferrules onto the tubing. On the other hand, threaded-pipe

Troubleshooting Fluid Power Systems: A Blend of Art and Science
to pull out the tool kit as well as some diagnostic tools. Any system problem can be solved with three essential parts: * Pressure gauges. * Flow meter. * A way to create a false load on the system. Not all troubleshooting operations need these tools but they should be close at hand. The challenge
