Why is the impeller structure of the AFP submersible sewage pump so unique?

In the field of sewage treatment, the AFP submersible sewage pump has gradually become the preferred equipment for many engineering projects with its high efficiency and reliable performance. And its unique single-blade or double-blade impeller structure has become the core technical highlight of this product, laying a solid foundation for its sewage discharge capacity. So why does the AFP submersible sewage pump adopt this unique impeller structure?

AFP submersible sewage pumps are mainly used to treat various types of complex sewage, which often contain a large amount of solid particles, fiber impurities and other pollutants. The traditional ordinary impeller structure often seems to be powerless when facing such a complex medium. Because ordinary impellers have more blades and relatively narrow flow channels, when solid particles in sewage pass through, it is very easy to get stuck and blocked between the blades or in the narrow flow channel. This will not only reduce the flow capacity of the pump, but in severe cases it will even cause pump failure, affecting the normal operation of the entire sewage treatment system.

In order to solve this problem, the research and development team of the AFP submersible sewage pump designed a unique single-blade or double-blade impeller structure after in-depth research and repeated experiments. This innovative structural design fundamentally changes the flow mode of sewage in the pump and the path of solid particles. Compared with ordinary impellers, single-blade or double-blade impellers effectively increase the medium passing area. When sewage enters the pump body, the larger passing area allows the sewage to flow more smoothly, reducing flow resistance and improving flow efficiency.

Especially important, when there are solid particles with larger diameters in the sewage, the unique impeller structure of the AFP submersible sewage pump shows great advantages. Generally, when there are solid particles with a diameter of about 50% of the pump diameter in the sewage, it is difficult for ordinary impellers to allow these large particles to pass smoothly, but the single-blade or double-blade impeller of the AFP submersible sewage pump can deal with it cleverly. Due to the reduction in the number of blades, a more spacious and unobstructed flow channel is formed inside the impeller. When solid particles pass through the impeller, there is more space and a more direct path, which makes it easier to pass, greatly reducing the possibility of particles getting stuck and blocked in the pump. This unique design is like opening up a "green channel" for solid particles in sewage, ensuring the smoothness of the flow.

From the perspective of fluid mechanics, the impeller structure design of the AFP submersible sewage pump fully considers the flow characteristics of the medium. During the operation of the pump, the impeller rotates at high speed, driving the sewage to generate centrifugal force, thereby realizing the transportation of sewage. When the single-blade or double-blade impeller rotates, it can form a relatively uniform flow field in the pump cavity, avoiding the situation where the local flow rate is too high or too low. This not only helps to improve the overall performance of the pump, but also reduces the wear on the internal components of the pump body and extends the service life of the pump.

In practical applications, the unique impeller structure of the AFP submersible sewage pump has withstood the test of various complex working conditions. Whether in urban sewage treatment plants, facing a large amount of sewage containing domestic garbage, silt and other impurities; or in industrial wastewater treatment occasions, dealing with wastewater with complex components such as chemicals and industrial waste residues, the AFP submersible sewage pump can operate stably and efficiently complete the sewage discharge task. Its flow capacity and anti-clogging performance play an important role in ensuring the stable operation of the sewage treatment system.

AFP submersible sewage pumps use a unique single-blade or double-blade impeller structure, which is based on a deep understanding of the actual needs of sewage treatment and the innovative application of advanced technologies. This structural design effectively solves the jamming and clogging problems faced by traditional impellers when treating complex sewage, and greatly improves the flow capacity and reliability of the pump. With the continuous development of sewage treatment technology, AFP submersible sewage pumps, with their unique impeller structure, will surely play an important role in more fields and contribute to improving environmental quality and promoting sustainable development.
