Description
Rotor:
Shape : Typically a helical or screw-shaped metallic component.
Function : Rotates within the stator, creating cavities that move fluid from the inlet to the outlet.
Material : Usually made of steel or other durable metal.
Eccentricity : The rotor’s design often involves an eccentricity, or offset, which is crucial for the formation of sealed cavities.
Durability : The rotor is generally designed to be more durable than the stator, often outlasting several stators in applications where the fluid doesn’t contain abrasive particles.
Stator :
Shape :
A stationary, typically elastomeric, component with an internal cavity that matches the shape of the rotor.
Function :
Provides the required sealing to direct the fluid flow and, along with the rotor, forms the cavities that transport the fluid.
Material:
Commonly made of rubber or other elastomers for flexibility and to facilitate the creation of complex internal shapes.
