  • Darrieus wind turbine Wikipedia

    When the rotor is stationary, no net rotational force arises, even if the wind speed rises quite high—the rotor must already be spinning to generate torque. Thus the design is not normally self-starting. Under rare conditions, Darrieus rotors can self-start, so some form of brake is required to hold it when stopped.

  • Progressive cavity pump Wikipedia

    The progressive cavity pump normally consists of a helical rotor and a twin helix, twice the wavelength helical hole in a stator. The rotor seals tightly against the stator as it rotates, forming a set of fixed-size cavities in between. The cavities move when the rotor is rotated but their shape or

  • Precision CNC Supercharger Rotor Modern

    29-9-2019· The accurate, non-contact meshing of two helical rotors inside a casing is the key for proper function of twin-screw superchargers. With the Whipple design, the male rotor has three helical lobes and the female has four, explains Supercharger Designer Garrett Bright. These rotate counter to each other and extremely closely.

  • Plastic Granulator Plastic Recycling Machine

    Helical Rotor In a helical rotor granulator, knives are arranged in a helix or spiral design in a closed rotor. Unlike open rotors of the previously discussed granulator types which are well suited for injection or extrusion plastic scrap, a closed-rotor design is robust, durable, and can withstand greater impact load, perfect for granulating thick cross-components.
