They transmit the power of the motor to the impeller through the connection between the shaft and the impeller, thereby realizing water transportation. However, traditional centrifugal pumps have some defects in long-term use: the bearings in traditional centrifugal pumps often need to withstand high-speed rotation and water pressure for a long time, which are prone to wear and failure, resulting in reduced pump performance and shortened service life; due to the mechanical connection between the shaft and the impeller, traditional centrifugal pumps have energy loss during energy transfer, resulting in low pump efficiency and low energy utilization; traditional centrifugal pumps have complex structures and high maintenance and maintenance costs. They are practical in complex irrigation water sources, and impurities such as aquatic plants are easily introduced, causing the centrifugal pump to get stuck, and aquatic plants are easily entangled on the surface of the rotating shaft, affecting the normal operation of the irrigation system. In view of this, the existing problems are studied and improved, and a shaftless irrigation water pump is provided to solve the current problems, aiming to achieve the purpose of solving problems and improving practical value through this technology.
