Dies gibt uns die Möglichkeit, Werbe- und Websiteinhalte zu optimieren. Often, one of the scrolls is fixed, while the other orbits eccentrically without rotating, thereby trapping and pumping or compressing pockets of fluid between the scrolls. The scroll discharge and suction processes occur for a full rotation, compared to less than a half-rotation for the reciprocating suction process, and less than a quarter-rotation for the reciprocating discharge process. Scroll compressors are positive-displacement devices that work by internal compression. During the last fifty years, scroll technology for air conditioning and refrigeration compressors has advanced remarkably. SCROLL series is 100% oil-free and is equipped with a high efficient IE 3 Motor and operates with 61 db(A) (SCROLL 04) at low noise level and low vibration. They have casings filled with lubricant to prevent abrasion of the exterior of the pump tube and to aid in the dissipation of heat, and use reinforced tubes, often called 'hoses'. The orbiting scroll traps air in each of the chambers during rotation and then compressing it till the discharge port. Best Match. Die ölfreien Scrollkompressoren der Baureihen SF sind zuverlässig und kompakt. Leaks from axial gaps are prevented by the use of spiral-shaped tip seals, placed into grooves on the tips of both spirals. Thus the scroll mechanism is itself more tolerant of liquid ingestion but at the same time is more prone to experience it in operation. A scroll compressor (also called spiral compressor, scroll pump and scroll vacuum pump) is a device for compressing air or refrigerant. The scroll compression process is nearly 100% volumetrically efficient in pumping the trapped fluid. The relative motion is the same as if one were orbiting. An eccentric shaft can provide the orbital motion but the scroll must be prevented from rotating, typically with an Oldham-type coupling, additional eccentric idler shafts, or a bellows joint (particularly for high-purity applications). According to Emerson Climate Technologies, manufacturer of Copeland scroll compressors, scroll compressors have 70 percent fewer moving parts than conventional reciprocating compressors. [22], In 2006 a major manufacturer of food service equipment, Stoelting, chose to change the design of one of their soft serve ice cream machines from reciprocating to scroll compressor.
