Embodiment Construction

[0011] Such as figure 1 As shown, the water pump according to the embodiment of the present invention includes an impeller 1 and a sealed housing 2 for accommodating the impeller 1. The impeller 1 is provided with multi-stage blades 11 along the direction of the impeller shaft. The radii above are unequal, that is, the radii of adjacent blades in the axial direction are different; the casing 2 is provided with a water inlet 21 along the axial direction of the impeller 1 , and a water outlet 22 is provided along the radial direction of the impeller 1 .

[0012] figure 1 In the water pump shown in , the blades 11 increase sequentially based on the flow direction of the liquid along the impeller shaft, and the water outlet 22 is set at the blade with the largest radius; on the contrary, the blades 11 can be set in order based on the flow direction of the liquid along the impeller shaft Reduced, and the water outlet 22 can be located at the blade with the smallest radius. By ado...

Abstract

The invention discloses a water pump which comprises a vane wheel and a shell body containing the vane wheel. The vane wheel is provided with multistage vanes along an axial direction, and the radius of the vanes are unequal along the axial direction of the vane wheel. A water inlet is arranged on the shell body in the vane wheel axial direction, and a water outlet is arranged in the radial direction of the vane wheel. According to the water pump, the vanes of the vane wheel are arranged in a multistage mode, and the radius of the vanes are unequal along the axial direction of the vane wheel, the pressure and flow speed of fluid are changed through each stage of vanes, the pressure of the water outlet is changed up to usage requirement after multistage changes, and the efficiency of the water pump is equivalently improved.

Description

technical field [0001] The invention is a water pump. Background technique [0002] A water pump is a machine that transports liquid or pressurizes the liquid. In order to better improve the kinetic energy of the transported liquid, or increase the pressure of the liquid, it is necessary to increase the speed of the pump impeller or increase the torque of the impeller, such as increasing The radius of the impeller is currently the most common way to change the number of blades of the impeller, that is, to combine the blades and use multiple blades to set up in layers to increase the water pressure. However, this method uses blades of the same radius to increase the output of the power shaft energy, and does not increase pump efficiency. Contents of the invention [0003] The purpose of the present invention is to provide a water pump to solve the problem of low efficiency of the existing water pumps. [0004] The purpose of the present invention is achieved through the f...
