Working principle of scroll compressor

Working principle of scroll compressor 1. The pressure of the scroll compressor is generated due to the interaction between the scroll disks that make planetary motion. When one of the scroll disks makes planetary motion, the gas enters from the outer opening. 2. When the gas enters the scroll, the opening is closed 3. As the scroll continues to make planetary motion, the gas hydraulic pressure enters a smaller and smaller space 4. When the gas reaches the center, the exhaust pressure is reached 5. In fact, in operation, all six gas channels are in different compression stages, thus ensuring that the suction and exhaust processes are basically continuous and uninterrupted. The simple concept of vortex was first invented in 1905. The scroll is an involute spiral that meshes with the matching scroll to form a series of gradually expanding spaces that exist between the two components. When compressed, one scroll remains stationary (fixed scroll) ) While the other scroll (orbiting scroll) is allowed to make planetary motion (but not rotation) around the * discs. When this motion occurs, the space between the two discs is slowly moved to two The center of the scroll, while the volume is also reduced. When the space reaches the center of the scroll, the gas at high pressure is discharged through the channel in the center. During the compression process, several gas chambers are compressed simultaneously, forming a very smooth process. The suction process (outer part of the scroll) and the exhaust process (inner part) are continuous.
