Many people think that the three-blade Roots blower has one more blade than the two-blade Roots blower. They simply think that under the same condition of the center distance from the outer circle and the same radius, the two-blade Roots blower has a larger exhaust volume than the three-blade Roots blower. This is a reason. A wrong view. For involute impellers, since the area utilization coefficient has nothing to do with the number of impeller heads, that is, when an involute impeller is selected, the main parameters of the two-blade Roots blower and the three-blade Roots blower are the same. Their displacement is the same. When the blade shape is appropriately selected, the theoretical air delivery capacity of a three-blade Roots blower is greater than that of a two-blade Roots blower.
When the center distance and outer circle radius are the same, the three-blade Roots blower with arc blade type has a larger displacement than the two-blade Roots blower. The displacement of the involute blade fan has nothing to do with the number of rotor heads.
The mechanical properties of the blade rotor are better. Compared with the two-blade Roots blower, the gap between the impellers and the impeller and the casing can be better ensured.
The vibration and noise of the lobe rotor fan is smaller than that of the two-lobe Roots blower. The service life of the bearings used on the three-lobe rotor is about % longer than that of the two-lobe Roots blower. Moreover, the three-blade Roots blower can use a twisted blade rotor to reduce its noise and vibration, while the two-blade Roots blower cannot use a twisted blade structure due to structural limitations.
The two-blade Roots blower, especially the twisted blade type, is increasingly used in automobile supercharging due to its better noise and dynamic balance performance. With the development of mechanical processing technology, mass production of two-blade Roots blowers is no longer a problem. The processing efficiency of twisted blade rotors on CNC machine tools is also getting higher and higher.
