Novel impeller on water pump

Technical Field

The utility model belongs to the technical field of the part on the water pump, especially, relate to a novel impeller on water pump.

Background

At present, most impellers on a water pump are made of plastic or metal materials and are mainly used for guiding water flow; most of the diversion channels on the existing impeller are spiral, so that when the impeller rotates, water can be radially ejected out through centrifugal force; however, because the impeller needs to rotate, a certain gap is needed between the impeller and the pump body of the water pump, and the gap consumes part of the ejected water flow, so that the water quantity drained to the guide vane is reduced, and meanwhile, because the guide vane and the impeller are axially overlapped, the water quantity of the water flow ejected radially from the impeller and ejected into the guide vane is not high, so that the working efficiency is low; there is a need for improvement.

The utility model aims at providing a to the not enough of above-mentioned prior art existence, provide a novel impeller on water pump, it has the flow that can improve the rivers and cut into the stator, improves work efficiency's characteristics.

In order to realize the purpose, the utility model discloses the technical scheme who adopts is: a novel impeller on a water pump comprises an impeller body, wherein a shaft hole connected with a rotating shaft is formed in the impeller body, a flow deflector is arranged on the impeller body, a flow guide channel is formed between the flow deflector and the impeller body, a flow guide ring is arranged on a water outlet of the flow guide channel, two side surfaces of the flow guide ring are respectively attached to the end surfaces of the flow deflector, the bottom surface of the flow guide ring is attached to the bottom surface of the flow guide channel, and a flow channel for enabling water flow to flow upwards to a guide vane of the water pump is formed between the flow guide ring and the flow; or the inner wall of the drainage ring is attached to the outer peripheral surface of the flow deflector, the bottom of the drainage ring is attached to the impeller body, and a flow channel for water to flow upwards onto the water pump guide vane is formed between the drainage ring and the impeller body.

The cross section of the drainage ring is of a trapezoidal structure, the bottom end face of the drainage ring is flush with the bottom face of the impeller body, and the upper end face of the drainage ring is flush with the upper end face of the flow deflector.

A shunting guide vane is arranged between the flow deflectors, one end of the shunting guide vane is connected with the impeller body, and the other end of the shunting guide vane is attached to the inner wall of the drainage ring; a water passing gap is arranged between the side surface of the shunting guide vane and the flow guide channel.

After the structure is adopted, compared with the prior art, the utility model the advantage that has is: the utility model discloses a set up the drainage circle on the delivery port of water conservancy diversion passageway, it can become the axial flow with radial flow's rivers to the guide, can improve the discharge in the guide vane like this, and simultaneously, it can also prevent that rivers from spilling from the clearance of water pump, improves the water intake efficiency of guide vane.
