1：When and when |
2：Starting time |
|
Water is used or the same liquid is poured into the pump casing, and it starts up.
(the water that is necessary for self absorption is left by the syphon cut effect in the next time, and the next time
|
When the pump is started, the liquid in the pump flows from the swirl chamber to the air water separation chamber through the impeller by the impeller, and the liquid enters again into the impeller portion from the self suction circulation opening at the bottom of the air water separation chamber. In addition, a part of the liquid is sprayed from the siphon cut hole to the suction chamber side, and the siphon cut hole is sealed. |
3：Self inhalation |
4：Self inhalation |
| The suction force is generated in the center of the impeller by the continuous circulation of the liquid in the preceding description 2, and the air in the suction pipe is sucked into the air water separation chamber with the circulating liquid, and the light is exhausted to the discharge tube side by the specific gravity difference in the air water separation chamber, and the heavy liquid falls It becomes a circulating liquid again. With this repeated action, the air is exhausted in the suction pipe and gradually becomes vacuum. | As the air in the suction pipe is exhausted and the vacuum increases, the liquid gradually rises, and when the liquid enters into the pump casing, the suction is completed and the pump starts pumping. |
