Summary: | A self-suction device for horizontal pump end spindle linkage. A rotor is disposed in a pump cavity. The rotor rotatably sleeves a pump shaft. A cross section of the pump cavity is circular, while a cross section of the rotor is elliptical, and the major axis of the ellipse is as long as the diameter of the circle. A sliding passage communicates with the pump cavity by means of a notch formed in the pump cavity. A block piece is disposed in the sliding passage in such a manner of sliding up and down, and seals the sliding channel. Rotating shafts are disposed at two sides below the block piece; rolling sliding pieces rotatably sleeve the rotating shafts, and bottoms of the sliding pieces prop against the top of the rotor. The bottom of a floater is connected with the block piece by means of a connecting rod penetrating through the bottom of a tank. A one-way outlet valve for discharging a fluid outwards is disposed at the top of the tank. A suction opening is formed at one side of a pump body, and a discharge |
