[0002] A water pump is a machine for transporting liquids or increasing the pressure of liquids. It transmits the mechanical energy of the prime mover or other external energy to the liquid, increasing the energy of the liquid. It is mainly used to transport liquids including water, oil, acid-base liquids, emulsions, suspension liquids, and liquid metals, etc. It can also transport liquid-gas mixtures and liquids containing suspended solids. The technical parameters of the water pump performance include flow rate, suction lift, head, shaft power, water power, efficiency, etc.; according to different working principles, it can be divided into types such as positive displacement water pumps and vane pumps.

[0003] The Chinese authorized utility model patent (publication number: CN219139443U) discloses a multi-step corrosion-resistant water pump drive shaft, including a workbench. One side of the workbench is fixedly installed with two support seats, the two support seats are symmetrically installed, a water pump body is fixedly installed between the two support seats, a disassembly component is arranged on the side of the workbench close to the water pump body, and feet are fixedly installed at the four corners of the lower surface of the workbench. By setting the disassembly component, the drive shaft in the water pump can be separated from the shaft of the motor, and the water pump drive shaft can be replaced and maintained very conveniently. And an anti-corrosion coating is applied on the drive shaft, avoiding the situation that the water pump shaft is damaged and cannot be used due to liquid corrosion. Two groups of fan blades are arranged on the drive shaft, which can increase the power of the water pump during the pumping work and make it easier to drain water, improving the flow rate of the water pump.
