【標(biāo)題】

The pipe length between the suction surface of the vortex sewage self-priming pump and the pump inlet should be less than the pump mounting height plus 2. The difference is that the backwater does not flow to the outer edge of the impeller, but to the impeller inlet. When the self-priming pump is activated, the reflux valve under the front of the impeller must be opened so that the liquid flow in the pump returns to the impeller inlet. The water is mixed with the air from the tube under the action of high speed rotation of the impeller, forming a mixture of gas and water to the separation chamber. Here the air is discharged and the water is returned from the reflux valve to the impeller inlet. So repeated until the air drained and sucked in the water. Flow along the worm shell. As the liquid in the worm shell constantly impact the cascade, constantly crushed by the impeller, with the air strongly mixed mixing, the formation of gas-water mixture, and continuous flow caused by the gas water can not be separated. The mixture is stripped by the tongue at the outlet of the worm shell and enters the separation chamber along the short tube. In the separation chamber the air is separated and drained by the outlet tube, while the water still flows through the left and right backwater holes to the outer edge of the impeller and is mixed with the tube air.
