Single-channel pipeline booster pump for boosting pressure by utilizing propelling principle of inner spiral structure of rotating body

The invention discloses a single-channel pipeline booster pump for boosting pressure by utilizing a propelling principle of the inner spiral structure of a rotating body. The single-channel pipeline booster pump adopts the working principle that when the rotating body drives a spiral channel (10) to rotate around a rotating shaft (12) in a rotating direction ( shown as 11 in the figure), an inlet (13) of the spiral channel of the rotating body eccentrically rotates relative to the rotatory central line of the rotating body, so that liquid is pressed in the spiral channel of the rotating body (14, shown as the direction of liquid entering the channel), and the liquid is driven to eccentrically rotate in the spiral channel; resultant force (20) which is parallel to the direction of the channel is formed by centrifugal force (18) generated by the liquid, and the resilience force (19) of the wall of the channel; the direction of the resultant force is the same as the flowing direction of the liquid, so that the resultant force has the effect of pressure boosting. Through the continuous pressure boosting of the channel, the liquid reaching a certain flowing speed and certain pressure is ejected out (16, shown as the ejecting direction of the liquid ) from the outlet (15) of the channel. The whole course that the liquid flows in the pump and pressure boosting is performed is completed in the single channel, so that thread-shaped objects, such as hair, cannot be wound.
