Efficient energy-saving dredging stirring pump

A high-efficiency energy-saving dredging stirring pump belongs to the technical field of pumps. The stirring head is installed below the impeller through the impeller shaft, the motor lower end cover,the sealing shell and the water collecting chamber are integrally connected to form an oil chamber bearing seat, an annular cavity is formed between the shell and the motor shell, the water collecting chamber at the lower end of the annular cavity is communicated with the water collecting chamber, and the pump body is provided with symmetrical double-vortex flow channels. A pressure reduction hole is formed in the mechanical sealing cover, and the two cable leading-in devices are arranged on the motor upper cover and the outer surface of the stirring pump body respectively. Different from a common stirring pump in structural design of an impeller, a pump body, an auxiliary impeller, an oil chamber bearing seat, a cable leading-in device and the like, the stirring pump can discharge mediawith the concentration bei
