(1) The structure of the suction cup and the arrangement of the suction pipe should allow the parallel pump to suck in the liquid equally and require that the suction nozzle should have a certain submergence depth (H1) in the suction cup, There is a certain dangling height (He), see Figure 2-126. (2) suction liquid inlet pipe, return pipe, waste collection pipe to stay away from the suction nozzle of the water pump to prevent air bubbles in the absence of vapors were quickly inhaled, while the suction pipe can not be placed in the pool center, It should not be too close to the pool wall (typically a minimum of 1.5D from the pool wall) to avoid vortex or evacuation (see Figure 2-126). (3) to ensure good sealing pipe joints, to avoid air leakage. (4) suction pipe layout should avoid the formation of airbag parts (see Figure 2-127).
