Abstract
The utility model relates to an energy-saving compound impeller of a water pump. The energy-saving compound impeller comprises an impeller and a pump chamber shell, wherein a water inlet and a water outlet are formed on the pump chamber shell; an impeller water inlet pipe is arranged on the impeller and is connected with the impeller; an auxiliary impeller is arranged in the impeller water inlet pipe; a water guide column is arranged in the middle of the auxiliary impeller; a vane of the auxiliary impeller is a helical vane and is fixedly connected to the side wall on the outer side of the water guide column; the water guide column is arranged on the axis of the impeller water inlet pipe, and one end of the water guide column on the inner side is connected with an impeller shaft; and the helical direction of the helical vane of the auxiliary impeller is the same as that of the vane of the impeller. The helical vane is arranged in the water inlet to ensure that the water entering the impeller enters the impeller in a helical shape to conform to the rotation direction of the impeller, so that the water flow resistance in a pump chamber is reduced, the water flow speed is accelerated, the water pressure is increased, the pump lift can be improved, more energy is generated by electric power, and then the electrical energy is saved.
Description
Technical field
The utility model relates to a kind of water pump, particularly relates to a kind of energy-conservation composite impeller of water pump.
Background technique
Centrifugal pump is one of general water pump, is widely used in every field, and the efficiency of centrifugal pump of prior art is low, and power consumption is large, and this depends primarily on the quality of impeller, and general centrifugal pump is single group impeller, and the hydraulic pressure that the impeller of this impeller produces is low, and lift is low.
Summary of the invention
The purpose of this utility model is exactly the defective that exists for prior art, and a kind of energy-conservation composite impeller of water pump is provided.
For achieving the above object, the utility model adopts following technological scheme:
A kind of energy-conservation composite impeller of water pump, comprise: impeller, pump chamber shell, the pump chamber shell is provided with water intake and water outlet, described impeller is provided with the impeller intake pipe, and the impeller intake pipe is connected with impeller, is provided with auxiliary impeller in the impeller intake pipe, the middle part of auxiliary impeller is provided with the water guide post, the blade of auxiliary impeller is on helical blade and the outside sidewall that is fixedly connected on the water guide post, and described water guide post is located on the axis of impeller intake pipe, and an end of its inboard is connected with impeller shaft; The Hand of spiral of the helical blade of auxiliary impeller is identical with the Hand of spiral of impeller blade.
The front end of described water guide post is taper or close to the curved surface of taper.
The described curved surface that is bordering on taper refers to that the front end of water guide post is bullet-headed.
The beneficial effects of the utility model: owing to be provided with helical runner in the water intake, make the water that enters impeller enter in the shape of a spiral impeller, just in time complied with the direction of the rotation of impeller, resistance to water-flow in the pump chamber is reduced, water velocity is accelerated, and hydraulic pressure increases, thereby can improve lift, same electric power has produced higher energy, has therefore saved electric power energy.
