Vortex pump working principle
[Asia Fluid Network News] vortex pump blade type of pump equipment, it is more suitable for small flow, high lift the occasion. In other words, it is a more flexible and intelligent device. Vortex pump specifically what kind of equipment? Vortex pump principle is how to reflect it? Vortex pump working principle Vortex pump is mainly composed of impeller, pump body and pump cover. The impeller is a disk, and the leaves on the circumference are arranged radially. 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. Between the leaves of the liquid and liquid flow 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. 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 same "longitudinal vortex" as the impeller turns. The liquid particle velocity in the pump body flow path is less than the peripheral speed of the impeller. Vortex pump work is based on the rotary impeller on the liquid force, in the direction of the liquid flow to the liquid in the impulse to transfer kinetic energy in order to achieve liquid-conveying pump. The impeller is a disk of the same thickness, with a large number of radial blades on either side of its outer edge. In the corresponding parts of the pump shell has a constant cross-section of the annular flow channel, the entire flow channel is divided into a suction tongue, the two rows, respectively, with the pump suction and exhaust pipe connected. The liquid in the pump rotates with the impeller to generate a certain centrifugal force, thrown out into the annular flow passage in the pump housing, and is forced to flow back under the restriction of the flow passage shape to re-enter the other back flow passage from the root of the impeller. The use of each device requires a thorough understanding of how it works, not only to help later work but also to respond promptly to problems or conditions on the device. The development of many products or devices in our country is still going on. Many devices can not be used very well. More work and support are needed at this time.
