The vortex pump, also known as the vortex pump, which is a vane pump, the main impeller, pump and pump cover composition, then the pump working principle is what? The following is about the working principle of the vortex pump Introduction. The working principle of the vortex pump Introduction Vortex pump impeller is a disc, the leaves on the circumference are radial uniform arrangement. An annular flow passage is formed between the pump body and the impeller, and the suction inlet and the discharge outlet are both located at the outer circumference of the impeller. There is a partition between the suction port and the discharge port, thereby isolating the suction port from the discharge port. We divide the fluid in the pump into two parts: the fluid between the blades and the fluid inside the fluid path. When the impeller rotates, the centrifugal force causes the circumferential velocity of the liquid in the impeller to be greater than the circumferential velocity of the liquid in the flow path, so that the "annular flow" shown in FIG. 1 is formed. Again, as the liquid from the suction inlet to the discharge outlet follows the impeller, the combined result of these two movements causes the liquid to produce the "longitudinal vortices" shown in Figure 2 (green) that are the same as the impeller steering. So get the name of the vortex pump. It should be specially pointed out that the liquid particles in the pump body circumferential velocity less than the impeller circumferential velocity. In the longitudinal vortex process, the liquid mass enters the impeller blades several times and transfers the energy to the liquid particles in the flow channel through the impeller blades. Every time the liquid particle passes the leaf, it gains energy once. This is also the case of the same impeller diameter, the vortex pump vane pump head higher than other reasons. Not all liquid particles pass through the impeller. As the flow rate increases, the "annular flow" weakens. When the flow is zero, the "ring flow" the strongest, the highest lift. Since the liquid in the flow channel is impinged by the liquid to transfer energy. At the same time also cause a greater impact loss, so the efficiency of the vortex pump is relatively low.
