r_r __ _ - 3_ Roots blower It is a type of positive displacement fan. It has two three-bladed impellers that rotate relatively in a space sealed by the casing and wall panels. Because each impeller adopts an involute or an epicycloidal envelope: Impeller machining profile, the three blades of each impeller are exactly the same, and the two impellers are also exactly the same, which greatly reduces the processing difficulty. The impeller is processed using CNC equipment, which ensures that when the center distance between the two impellers remains unchanged, no matter where the two impellers rotate, a certain minimum gap can be maintained to ensure that gas leakage is within the allowable range.
The two impellers rotate toward each other. Since the gaps between the impellers, the impellers and the casing, and the impellers and the wall panels are extremely small, a vacuum state is formed in the air inlet, and the air enters the inlet under the action of atmospheric pressure. Then, two of the blades of each impeller, the wall panel, and the casing form a sealed cavity. During the rotation of the impeller, the air in the intake cavity is continuously brought to the exhaust cavity by the sealed cavity formed by the two blades. , and because the impellers in the exhaust chamber are meshed with each other, the air between the two blades is squeezed out. With continuous operation, the air is continuously transported from the air inlet to the air outlet. This is The entire working process of Roots blower.
