Nanchang scroll oil-free air compressor | Scroll oil-free air compressor definition
/ Picture
Air is sucked in from the suction port on the outside of the solid scroll. The air enclosed in the compression space is compressed toward the center due to the contraction of the compression chamber caused by the rotational motion. The compression space becomes the smallest at the center, and the air that has been compressed to the maximum extent is squeezed out from the exhaust port in the center. The movement of (inhalation rrr compression rrr exhaust) is repeated.
/ Picture
It is formed by the mutual engagement of the moving and stationary vortices with two double function equation lines. During the working process of suction, compression and exhaust, the static plate is fixed on the frame, and the moving plate is driven by the eccentric shaft and controlled by the anti-self-propagation mechanism. It rotates in a plane with a small radius around the center of the base circle of the static plate. The gas is sucked into the periphery of the static disk through the air filter element. As the eccentric shaft rotates, the gas is gradually compressed in several crescent-shaped compression chambers formed by the engagement of the moving and static disks, and then is continuously discharged from the axial hole in the central part of the static disk.
