A rotary-vane compressor is also known as a rotary piston compressor because the function of the vane is similar to that of a piston (shown in Figure 3). The Swing Compressor is an electro-dynamic reciprocating device that connects directly to the piston of the compressor. With only one moving part and no need for bearings, cranks or con-rods, the fatality rate is lowed significantly. ROCK SOLID ENGINEERING: Unlike most companies that continually procure parts from many sources, the Sawafuji Electric Co. Ltd alone has produced and improved the Engel Swing Compressor over many years. In this paper, a novel swing vane rotary compressor (SVC) was introduced, which had significant advantages—simple mechanism, reduced frictional loss, reliable operation, and a comparatively higher compression ratio. Conventional lubricant in a compressor generally consists of mineral oil — often from petroleum — which coats the compressor components and helps them glide freely as they operate. Think of compressor like your heart—as your heart pumps blood throughout the body, the compressor pumps refrigerant through the air conditioning system. endobj If the control signal is on the compressor, the smallest pressure swing possible is 7.8 psi within the VSD compressor’s turndown range.

Then it slowly increases the distance the piston travels each stroke until it reaches a full stroke. BUILT WITH A PURPOSE: Engel's swing motor is purpose built to with stand shock and vibration. One has blades or vanes that rotate … But if there is another imbalance within the air conditioner's condensing unit, the hot compressor can compound the problem. By the swing vane which tip is connected to cylinder via a hinge joint, SVC can effectively reduce frictional losses and improve mechanical efficiency at high speed. The compressor has no high start up current draw because when it starts up it can simply move down just a fraction then return. Engel 12-Volt Refrigerator Freezer Warmer: Introduction to 12-Volt Engel Fridge Freezers, (Has photos of All Engel Fridge Freezers), (Compare Chart for All Engel Fridge Freezers). 0000000936 00000 n It operates at 30 degrees angles and on rough corrugated dirt roads without losing efficiency. At some point there is a sizable cost associated with a rotary screw air end replacement, but they often last 10 yr or more. The inside of this type of AC compressor contains a shaft with several blades attached to it. Standard rotary compressor packages have a microprocessor-based or electro-pneumatic controller. CONTINUOUS IMPROVEMENT: Engel's commitment to continuous improvement means that the Engel of today is the most reliable, the most efficient ever, quieter and full of features to ensure it is easier to use than ever before. Many Engel owners testify to stories of car rollovers and collisions, units dropping off trucks and still performing. They are commonly used to replace piston compressors where large volumes of high-pressure air are needed, either for large industrial applications such as chillers, or to operate high-power air tools such as jackhammers and impact wrenches.
