Energy-saving combined impeller of water pump

Abstract

The invention relates to an energy-saving combined impeller of a water pump. The energy-saving combined impeller comprises an impeller body and a pump chamber shell, the pump chamber shell is provided with a water inlet and a water outlet, the impeller body is provided with an impeller water inlet pipe which is connected with the impeller body, an auxiliary impeller body is arranged in the impeller water inlet pipe, a water guide post is arranged in the middle of the auxiliary impeller body, blades of the auxiliary impeller body are spiral blades and are fixedly connected to the outer side wall of the water guide post which is arranged on the axis of the impeller water inlet pipe, and the inner end of the water guide post is connected with an impeller shaft; the spiral blades of the auxiliary impeller body and blades of the impeller body have the same spiral direction. As the spiral impeller body is arranged in the water inlet, water entering the impeller body is a in spiral shape and conforms to the rotating direction of the impeller body, water flow resistance in a pump chamber is reduced, water flow speed is increased, water pressure is increased, and therefore the hydraulic head can be improved; higher energy is produced through the same electricity, and therefore electric energy is saved.

Description

technical field [0001] The invention relates to a water pump, in particular to an energy-saving composite impeller of the water pump. Background technique [0002] Centrifugal pump is one of the common water pumps, widely used in various fields, the centrifugal pump in the prior art has low efficiency and high energy consumption, which mainly depends on the quality of the impeller, the general centrifugal pump is a single set of impellers, the impeller The water pressure generated by the impeller is low and the head is low.
