Relationship between pressure and current of a three-lobe Roots blower
There is a certain relationship between the pressure and the current of a three-lobe Roots blower. Generally, when the load (i.e., the output pressure and flow rate) of a Tricycle Roots Blower increases, its required current increases accordingly. This is due to the fact that more power is required to drive the blower to provide greater pressure.
Specifically, as the pressure of a triple-lobe Roots blower increases, its operating point shifts upward along the system characteristic curve. At the operating point, the blower needs to generate more back pressure to meet system requirements. In order to generate more back pressure, the motor needs to provide more power, so the current will increase accordingly.
It is important to note that the relationship between pressure and current is the same...
