Click hereWith the integration of the motor, VSD, and magnetic-bearing system, the capacitors required for the motor and drive can be used as a backup power source for the bearings in the event of a power outage or emergency shutdown.CAPACITY AND EFFICIENCYAmong the key parameters affecting performance are capacity (tons) and efficiency (kilowatts per ton). The compressor''s capacity ranges from 60 to 90 tons, depending on the operating conditions. Plans call for that range to be extended to 150 tons water-cooled and 115 tons air-cooled by the end of 2004 with the use of R-134a refrigerant. An R-22 version is planned for retrofit applications.Efficiency improvements stem from a combination of the centrifugal compressor, permanent-magnet motor, and magnetic bearings. Within the compressor, efficiency is affected by the compressor isentropic efficiency (the efficiency of the wheels), the motor, and the bearings. Traditional induction motors of this size typically are in the 92-percent efficiency range. This compressor''s permanent-magnet motor has an efficiency of 96 to 97 percent. What, Why, HowWorldwide radio-navigation GPS is possible due to a constellation of 24 orbiting satellites (plus three spares) and associated ground receivers.Terrestrial GPS receivers use the satellites as reference points to calculate positions accurate to a matter of feet. Advanced forms of GPS used by the military are accurate to less than an inch. Civilian GPS, previously accurate only to 100 yards, was improved ten-fold in May 2000, when President Bill Clinton ordered the U.S. military to stop intentionally degrading the satellite signals used by civilians. Now GPS essentially gives every square foot on the planet a unique address. Though light in weight, Airbor magnetic drill has a powerful 1.6-hp air motor and 1,600-lb magnetic holding strength. With its extra rack, stroke length is extended to 10 1/4 in. Annular cutter capacity is up to 2 1/16 in. diam. Geared chuck adapter converts the unit to a standard drill press. The Slugger Air Force pneumatic drill, at 24 lbs, 6 1/4" high, is useful for confined area drilling. The drill''s features include a permanent magnet that turns on or off by air power, a cutter capacity of up to 1 1/16" diameter x 3/4" depth and the ability to use ShortSlugger cutters and frame cutters. These cutters'' geometry allows the operator to drill multi-layered truck frames in a single pass. ©2003 www.band-saws-for-sale.com. All rights reserved. |
