Embodiment Construction

[0023] Below in conjunction with accompanying drawing and specific embodiment the present invention is further described:

[0024] like Figure 1 to Figure 5 As shown, an impeller includes an impeller main body 19, and a plurality of circumferentially distributed blades 20 are arranged on the impeller main body 19. A single blade 20 is a variable-angle logarithmic spiral structure, and the blade 20 is from the impeller The center of the main body 19 is gradually twisted to the edge of the impeller main body 19, reducing the axial power of the pump, improving the hydraulic efficiency, and improving the efficiency of the pump; the thickness of the blade 20 is gradually thinned from the edge of the impeller main body 19 to the center of the impeller main body 19, improving the blade 20. The wear condition of the blade 20 is prevented from clogging; the variable-angle logarithmic spiral structure refers to the algorithm of the logarithmic spiral according to the algorithm of the l...

Abstract

The invention relates to an impeller which comprises an impeller body. Multiple blades distributed in the circumferential direction are arranged on the impeller body; and each blade is gradually warped from the center of the impeller body to the edge part of the impeller body. The invention further relates to a slurry pump which comprises a welding bottom plate. A motor and a bracket are fixed onto the welding bottom plate; a shaft seal transmission part is arranged on the bracket; a pump shaft is connected into the shaft seal transmission part; a coupler is arranged at one end of the pump shaft; a pump body is arranged at the other end of the pump shaft; and the pump shaft is connected with the motor through the coupler. The slurry pump further comprises the impeller; a pump body is a sealed chamber; and the impeller is arranged in the chamber and is fixedly connected with the pump shaft. The impeller and the slurry pump provided by the invention are reasonable in structure design andbeneficial to improving the efficiency of the pump.

Description

technical field [0001] The invention relates to the technical field of slurry pumps, in particular to an impeller and a slurry pump. Background technique [0002] Slurry pumps are widely used in mining, metallurgy, electric power and environmental protection and other industries and fields involving solid-liquid two-phase medium transportation. Slurry pumps increase the energy of solid-liquid mixed media by means of centrifugal force, and convert electrical energy into media. Kinetic and potential energy devices. The blades of general industrial two-phase flow pumps are cylindrical, and the specific speed of the pump is generally low, and the circular arc and involute are used later. Since the medium conveyed by the pump contains more solid particles, the medium contains more solid particles. The hard solid particles in the pump will have a strong abrasive effect on the flow part of the pump, resulting in shortened service life of the pump. The blades used at this stage are...
