The invention discloses a self-priming pump. The self-priming pump comprises a pump body, an impeller and a motor; the impeller comprises a front impeller plate, a rear impeller plate and a pluralityof involute diversion bars evenly distributed in the circumferential direction between the front impeller plate and the rear impeller plate, an axle fixing flange is arranged at the center of the rearimpeller plate, a rotating shaft of the motor is connected with the axle fixing flange, and the spacing exists between the inner ends of the involute diversion bars and axle fixing flange; and an impeller mouth ring is arranged at the center of the front impeller plate and communicates with an irrigation channel formed by a plurality of intervals, a water outlet cavity is formed between the two adjacent involute diversion bars, a plurality of notches are evenly formed in the outer wall of the front impeller plate in a circumference mode, and the notches correspond to a plurality of water outlet cavities one by one. By means of the self-priming pump, the water in a water inlet channel can be quickly absorbed into an impeller chamber, the water absorption speed is improved, and the air is quickly exhausted.
Description
technical field [0001] The invention is a self-priming pump. Background technique [0002] Usually, the water inlet and the water outlet of the self-priming pump body are on the same horizontal line, and the water inlet and the water outlet are located on both sides of the pump body, and are connected to the water inlet chamber and the water outlet chamber respectively, and the water inlet chamber is connected to the water inlet channel. The water outlet chamber is connected to the water outlet channel, and an impeller chamber is arranged between the water inlet channel and the water outlet channel. figure 1 As shown, at the end of the work, the water in the water outlet cavity 103 is discharged from the water outlet, which causes a large volume of air to accumulate in the water outlet cavity. The water port enters and mixes with a certain amount of air and finally enters the impeller chamber 102. Then, the water mixed with air enters the water outlet chamber 103. Because t...
