Fuyang pump mixed flow pump product concept

"What is a mixed flow pump? Mixed flow pump this equipment, put it plainly point centrifugal pump and axial pump is a combination of both the advantages of centrifugal pumps and axial flow pump is a The ideal pump. "Recently, Wang Fu, Hebei Fuyang Pump Co., Ltd. interviewed Asia Fluid Network Xiaobian, and Xiaobian chat Fuyang pump this" special "mixed-flow pump products. Now, let's get a closer look at Francis pump products. Fuyang pump mixed flow pump product concept According to Wang introduced, mixed flow pump in appearance, principle, performance and other aspects are between the centrifugal pump and axial flow pump, because of this, the mixed flow pump to become a centrifugal pump and axial flow pump A combination of both the advantages of both. Mixed-flow pump shape From the appearance, volute-type mixed flow pump shape resembles centrifugal pump; and guide vane-type mixed flow pump is much like the appearance of axial flow pump. Francis pump impeller short shape, part of the centrifugal pump impeller, and some like the axial pump impeller, the blade is a spiral twisted leaves. The working principle of the mixed flow pump From the working principle of the mixed flow pump, the high-speed rotation of the impeller produces the centrifugal force of the centrifugal pump as well as the thrust force of the axial flow pump. The mixed flow pump works by the mixture of these two forces. Mixed-flow pump performance from the use of mixed-flow pump performance is also between the centrifugal pump and axial pump, compared with the centrifugal pump, the lower head, while the larger flow; compared with the axial pump, head higher, but Traffic is smaller. The mixed flow pump speed higher than the centrifugal pump, lower than the axial flow pump, generally between 300-500. In this regard, Wang further explained that the use of mixed-flow pump performance parameters to represent, such as flow, lift, power, efficiency, speed and so on. In a certain speed, the flow as a variable, that is, if you change the flow of the pump, the pump head, power and efficiency are all changes. The relationship between these changes in the law, drawn together into several curves to represent, this is the pump performance curve. Mixed-flow pump performance curve shape Mixed-flow pump performance curve shape is also between the centrifugal pump and axial pump, for high-lift mixed-flow pump, the flow and lift, flow and power changes in the law close to the centrifugal pump, On, can be closed by the valve to start, when the minimum power, power machine safety. For the low-head mixed-flow pump, the variation law between the performance parameters is close to the axial flow pump. In use, the valve should not be used to start the valve, but should start the valve when the power is relatively small, the motor is not easily burned. In addition, Wang also said that the mixed flow pump sets the advantages of centrifugal pumps and axial flow pump, simple structure, high efficiency area, easy to use, suitable for plain polder farmland irrigation and drainage pump stations. However, on the other hand, the development and application of mixed-flow pumps still have a certain gap compared with centrifugal pumps and axial-flow pumps. The advantages of mixed-flow pumps have not yet been fully understood and fully developed yet to be studied. "Fuyang pump industry will also be like a mixed-flow pump, which will keep its development in harmony and absorb the essence of all parties and strive to develop itself." Wang finally said.
