Vortex pump, also known as the vortex pump, it is a vane pump, the main impeller, pump body and pump cover composition, then the pump working principle is what?
The impeller of the vortex pump is a circular disc, and the blades on the circumference of a circle are arranged in radial uniform arrangement. The annular flow passage is formed between the impeller and the pump body, the inlet and outlet of the impeller in the outer circumference. A partition plate is arranged between the suction port and the discharge port, and the suction port and the discharge port are separated from each other.
The liquid in the pump is divided into two parts: the liquid between the blades and the liquid in the flow passage. When the impeller rotates, under the action of the centrifugal force, the liquid in the impeller is faster than the circumferential velocity of the liquid in the flow passage, so it is shown in Figure 1 ". Also because of the self suction mouth to discharge liquid with the impeller forward, the two kinds of movement of the results of the synthesis, so that the liquid generated with the impeller to turn the same figure 2 (green) shows the vertical vortex". Thus get the name of the vortex pump. It is pointed out that the circumferential velocity of the liquid particles in the pump body is smaller than the circumferential velocity of the impeller.
