Multi-suction sewage pump one, multi-suction sewage pump working principle, multi-suction sewage pump is a volume to one, figure 2-10 is its structure Diagram. It is by the pump body, pump cover, eccentric rotor and between the formation of the volume (called unit volume) of the periodic change of suction, discharge liquid pump. As can be seen from figure, the pump rotor is cylindrical, the rotor has a number of slots, each slot is equipped with a slide. The rotor is installed eccentrically in the pump casing, and its ECCENTRICITY IS E. The sliding vane can slide radially in the slot of the rotor. The sliding plate is pressed against the shell by Centrifugal Force, spring force or liquid pressure, so that the end of the sliding plate is pressed against the Shell to ensure sealing. The inlet and outlet are sealed apart by a small gap between the rotor and the shell. As the rotor rotates, the unit volume on the suction side increases and the liquid is sucked into the unit volume. When the primary volume reaches the maximum, the monomer volume is separated from the suction port and communicated with the discharge port. As the rotor continues to rotate, the volume of the element decreases and the liquid is discharged. Rotor rotation around, slide in the slot to and fro once, the volume of each unit increased, decreased once, to complete a suction, discharge process. If the pump into a variable eccentricity structure, you can adjust the flow. If made into a two-time inhalation, two-time discharge structure, it is called double-acting multi-suction sewage pump.
