 [FIGURE 1-2 OMITTED]When the magnetic bearings are energized, the motor and impellers, which are keyed directly to the magnetic shaft, levitate. Permanent-magnetic bearings do the primary work, while digitally controlled electromagnets provide the fine positioning. Four positioning signals per bearing hold the levitated assembly to a tolerance of 0.00002 in. As the levitated assembly moves from the center point, the electromagnets'' intensity is adjusted to correct the position. These adjustments occur 6 million times a minute. The software has been designed to automatically compensate for any out-of-balance condition in the levitated assembly.SHUTDOWNS AND POWER FAILURESWhen the compressor pneumaticthrottlecontrolforgaspoweredaircompressors is not running, the shaft assembly rests on graphite-lined, radially located touchdown bearings. The magnetic bearings pneumaticthrottlecontrolforgaspoweredaircompressors normally position the rotor pneumaticthrottlecontrolforgaspoweredaircompressors in the proper location, preventing contact between the rotor and other metallic surfaces. If the magnetic bearings fail, the touchdown bearings (also known as backup bearings) are used to prevent a compressor failure. Gas cylinders and dewars are becoming relics thanks to the advent of gas-generation systems. These generators turn compressed gas into nitrogen, and deionized water into hydrogen gas. Over the last several years, advances in technology have significantly increased use of these on-site gas generators. Membranes, specialized adsorbents and catalysts, improved air compressors, and enhanced electronic controls have fueled this wave of progress.Gas pneumaticthrottlecontrolforgaspoweredaircompressors generators provide consistent, reliable, on-site supplies of gases that are instantly ready for use. And since gas generators eliminate the need to store gases, they also do away with injuries caused by lifting and dropping heavy metal cylinders. Doing away with cylinders also eliminates the costs of maintenance, shipping, returning, and storing them. There is also no need to keep pneumaticthrottlecontrolforgaspoweredaircompressors hydrogen generators away from pneumaticthrottlecontrolforgaspoweredaircompressors oxidizing gases or to locate generators in specially constructed areas.
