[0002] The water pump contains important components such as the motor and impeller. The impeller is the core component of the water pump. The impeller is a wheel disk equipped with moving blades, which can refer to the general term for the wheel disk and the rotating blades installed on it. The shape and size of the water pump impeller are closely related to the performance of the water pump. The water pump impeller can generally be divided into single-suction and double-suction types. The single-suction impeller absorbs water on one side; the double-suction impeller absorbs water on both sides. The impellers of large-flow water pumps all use double-suction impellers.

Although some existing water pumps are equipped with filtering devices, the filtering devices cannot filter out some fine impurities such as mud and sand. After the mud and sand enter, they will wear the internal components of the water pump and damage the impeller blades, causing damage or wear to the blades, thereby weakening the working performance of the impeller.

[0004] Furthermore, the performance of the impeller determines the performance of the water pump.
