Because the clearance between impeller and impeller, impeller and casing, impeller and wallboard is very small, in the process of impeller rotation, the vacuum state is formed at the air inlet, air is sucked into the air inlet cavity under the action of atmospheric pressure. With the continuous rotation of impeller, two blades of each impeller and wallboard, casing form a sealed cavity, the air of air inlet cavity is continuously taken to exhaust cavity by the sealed cavity formed by two blades. Because the impeller in exhaust cavity is intermeshed, the air between two blades is extruded. After continuous suction and extrusion, air is continuously transported from air inlet to air outlet, and the whole gas transportation process is completed.
