1. The installation position of the self -suction pump should be as close as the water surface as much as possible to ensure that the air is not sucked into the air when the water level decreases.

  2. When installing the water absorption pipeline, the water intake pipe should always be tilted or horizontally installed in the direction of the water. Any point of the water inlet pipe should not be higher than the water pump into the water inlet, otherwise the air in the tube will be eliminated.

  3. To prevent the fillers from giving up the air leakage. The elasticity of the filler should be appropriate. If it is too loose, the filling cover should be tightened; the filler is damaged and failed, and the water seal pipes in the filler cover are blocked and heated. Essence

  4. Before installing the water inlet pipe connected to the French disk, you should clean up the planes of the two flanges in contact with each other. Add a 3 ~ 5mm thick glue pad in the middle. To gradually tighten the bolts in a few times.

  5. The bottom valve of the self -absorbing pump must have sufficient flooding depth. The depth of submerging from the valve plane should be equal to 1.5 to 2 times the outer diameter of the bottom valve, at least not less than 0.5m. If it is too shallow, it is easy to form vortex, which sucks the air, generates steam and damage the impeller and the pump shell. If you find that the water pump is running quickly when running, you can put a few wooden boards on the water surface to reduce the vortex and prevent the air from entering the pump shell.

  6. There is a deformed screw on the self -suction pump body. In order to facilitate the air deflation, the water faucet with the same thread size can be used instead of the air -to -air jacket.

  7. The vacuum of the self -absorbing pump is limited. The vacuum is too large, which can easily vaporize the water in the pump and be unfavorable to the self -absorbing pump. Therefore, their respective water pumps have their maximum allowable suction, and they are generally between 3 and 8.5m, and they should be controlled in this range during installation.

  8. Pay attention to exhaust. Before starting the self -absorbing pump, the water should be added to eliminate the air in the self -absorbing pump; usually open the airwalk plug on the pump cover regularly to eliminate the air accumulated in it.
