What are the differences between centrifugal impurity pump and vortex impurity pump?

From the working principle, the centrifugal impurity pump will first fill the pump with liquid before working, and then start the centrifugal impurity pump, in which the blade of the impeller drives the liquid to rotate, so the liquid flows to the outer edge of the impeller by inertia during rotation, and the impeller sucks liquid from the suction chamber. Generally, in this process, the liquid in the impeller flows around the blade, and the liquid acts a lifting force on the blade during the flow movement.

The working principle of vortex impurity pump is that when the impeller rotates, under the action of centrifugal force, the circumferential velocity of the liquid in the impeller is greater than that of the liquid in the channel, so it forms "annular flow". Since the liquid from the suction port to the discharge port moves forward with the impeller, the combined result of these two movements makes the liquid produce the same "longitudinal vortex" as the impeller. Hence the name of vortex pump.

Secondly, the difference between centrifugal pump and vortex pump is analyzed from the structure.

The structure of centrifugal pump is mainly composed of overflow components, including suction chamber, impeller and water pressure chamber. The suction chamber is located in front of the water inlet of the impeller and plays the role of guiding the liquid to the impeller; The water pressure chamber mainly includes spiral water pressure chamber (volute type), guide vane and space guide vane; The impeller is an important working element of the pump. The impeller is composed of a cover plate and a blade in the middle.

Some vortex impurity pumps are also called vortex pumps, regeneration pumps, etc. Because it sucks and discharges the liquid by the action of vortex motion generated by the liquid when the impeller rotates, it is called vortex pump. Some vortex pumps are also called vortex pump, regeneration pump, etc. It is called vortex pump because it sucks and discharges liquid by the action of vortex motion of liquid when the impeller rotates. At present, the flow of general vortex pump is 0.2 ~ 27m3 / h. General working principle of vortex pump when the prime mover drives the impeller in the pump to rotate through the shaft, the liquid enters the flow channel from the suction population, and is thrown into the surrounding annular flow channel under the centrifugal force of the rotating impeller to make the liquid rotate in the flow channel. Because each liquid particle is affected by centrifugal force, the liquid inside the impeller is greatly affected by centrifugal force, while the liquid in the flow channel is less affected by centrifugal force. Due to the different magnitude of centrifugal force, the liquid makes longitudinal vortex motion.
