Embodiment 1

[0013] Such as figure 1 , figure 2 The impeller of an external mixing self-priming pump is shown, the impeller is provided with a front cover 1 and a rear cover 2, a blade 3 is arranged between the front cover 1 and the rear cover 2, and the gas-liquid is evenly distributed on the outside of the cover As can be seen from the figure, the gas-liquid mixing sheet 4 is evenly distributed on the outside of the front cover plate 1. When the pump is initially working, the pump body has strong agitation, good gas-liquid mixing, short gas discharge time and high efficiency.

Embodiment 2

[0015] Such as image 3 , Figure 4 The impeller of an external mixing self-priming pump is shown, the impeller is provided with a front cover 1 and a rear cover 2, a blade 3 is arranged between the front cover 1 and the rear cover 2, and the gas-liquid is evenly distributed on the outside of the cover As for the mixing sheet, it can be seen from the figure that the gas-liquid mixing sheet 4 is evenly distributed on the outside of the rear cover 2 .

Embodiment 3

[0017] Such as Figure 5 , figure 2 , Figure 4 The impeller of an external mixing self-priming pump is shown, the impeller is provided with a front cover 1 and a rear cover 2, a blade 3 is arranged between the front cover 1 and the rear cover 2, and the gas-liquid is evenly distributed on the outside of the cover As for the mixing sheet, it can be seen from the figure that the gas-liquid mixing sheet 4 is uniformly distributed on the outside of the front cover 1 and the rear cover 2 respectively.

Abstract

The invention relates to an external mixing self-priming pump impeller, and relates to pumps. A front cover plate and a rear cover plate are arranged on the impeller; blades are arranged between the front cover plate and the rear cover plate; and gas-liquid mixing sheets are distributed on the outer sides of the cover plates uniformly. The gas-liquid mixing sheets are distributed on the outer sides of the cover plates uniformly, so during the initial operation of a pump, a pump body has strong stirring, good gas-liquid mixing, short time of gas discharge and high efficiency; and the impeller is suitable for an external mixing self-priming pump.

Description

technical field [0001] The invention relates to pumps, in particular to an external mixing type self-priming pump impeller. Background technique [0002] We know that the existing external mixing self-priming pump impeller is provided with a front cover and a rear cover on the impeller, a blade is arranged between the front cover and the rear cover, and the outer surface of the front cover and the rear cover The surface is smooth. The impeller of this external mixing self-priming pump has poor agitation in the pump body, poor gas-liquid mixing, long gas discharge time and low efficiency when the pump is initially working due to the smooth outer surfaces of the front cover and rear cover. Contents of the invention [0003] The technical problem solved by the invention is poor agitation in the pump body, poor gas-liquid mixing, long gas discharge time, and low efficiency. It provides a pump with strong agitation in the pump body, good gas-liquid mixing, and long gas dischar...
