The bottom of the storage tank is equipped with a drain outlet, and a discharge manifold is installed below the drain outlet. The water in the storage tank is supplied to the pressure operation equipment through the bottom discharge manifold.
[0003] When water flows from the drain outlet to the discharge manifold, a rotating vortex is formed near the top of the drain outlet. The vortex effect is more pronounced when the water flow velocity is high, resulting in a reduction in the amount of water discharged, which makes it difficult to meet the pressure operation requirements.
