1. Working principle
The main components in the scroll compressor are two involute scrolls with the same shape but 180° staggered angular phase position, one is a fixed scroll, and the other is driven by an eccentric shaft, the axis of which is around An orbiting scroll that revolves around the axis of the fixed scroll.
During the work, the two scrolls are tangent in many places to form a sealing line, and proper sealing at the end faces of the two scrolls are added, thereby forming a several-month-shaped air cavity. The sealing line at the common tangent point between the two scrolls is continuously shifted along the scroll curve as the orbiting scroll revolves so that the shape and size of these crescent-shaped air cavities are constantly changing. The suction port of the compressor is opened in the upper part of the fixed scroll casing.
