Harvey says the major contaminants they have found are rust and dirt, as well as water and algae. "Algae is actually our biggest problem. It lives on water in the fuel and results in a dark-purplish sludge in the tank."Most of the tanks we cleaned are used for irrigation," adds Harvey. "That means they sit out in the middle of a field all year. The exposure to dirt and condensation is probably greater than with a tank sitting at the farmstead." In both of these efforts, the tanks were cleaned by using a Cim-Tek VII fuel recycling system. Country Energy has helped make these units available to local cooperatives through their KleanSweep program. Fuel is pulled from the bottom of the tank by a suction wand and circulated through a screen and filter element with a 10micron particle rating. Cleaned fuel is then returned to the storage tank.
This article describes this new compressor technology and its first use in an ARI-certified chiller design.THE BEARINGSTraditional centrifugal compressors use roller bearings and hydrodynamic bearings, both of which consume power and require oil and a lubrication system. Recently, ceramic roller bearings, which avoid issues related to oil and reduce power consumption, were introduced to the HVAC industry. The lubrication of these bearings is provided by the refrigerant itself. (1)Magnetic-bearing technology is significantly different. A digitally controlled magnetic-bearing system, consisting of both permanent magnets and electromagnets, replaces conventional lubricated bearings. The frictionless compressor shaft is the compressor''s only moving component. It rotates on a levitated magnetic cushion (Figure 1). Magnetic bearings--two radial and one axial--hold the shaft in position (Figure 2).
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.
