How the vortex pump works
Vortex pumps, also known as vortex pumps, are vane pumps. Mainly by the impeller, pump body and pump and into. The impeller is a disk and the blades on the circumference are arranged radially and evenly. An annular flow channel is formed between the pump body and the impeller, and the suction inlet and the discharge outlet are located at the outer circumference of the impeller. There is a partition between the suction inlet and the discharge outlet, thereby separating the suction inlet from the discharge outlet.
We divide the liquid in the pump into two parts: the liquid between the leaves and the liquid in the flow channel. When the impeller rotates, under the action of centrifugal force, the peripheral velocity of the liquid in the impeller is greater than the peripheral velocity of the liquid in the flow channel, so that an annular flow is formed. Since the liquid from the suction inlet to the discharge outlet follows the impeller, the combined results of these two movements cause the liquid to produce the same longitudinal vortex as the impeller. So get the name of the vortex pump. It should be particularly pointed out that the peripheral velocity of the liquid particles in the flow channel of the pump body is less than the peripheral velocity of the impeller.
In the process of longitudinal vortexing, the liquid particles enter the impeller blades several times, and the impeller blades pass the energy to the liquid particles in the flow channel. Each time a liquid particle passes through the blade, it receives energy once. This is also the reason why the vortex pump has a higher lift than other vane pumps with the same impeller outer diameter. Not all liquid particles pass through the impeller. As the flow rate increases, the annular flow weakens. When the flow rate is zero, the annular flow is the strongest and the head is highest.
Because the liquid in the flow channel is transmitted through the liquid, energy is transferred. At the same time, it also causes a large impact loss, so the efficiency of the vortex pump is relatively low.
