How to choose nozzle in fountain design
Modern fountain design can be considered not only from the modeling, but also from the use conditions of the nozzle. A. sound. Some nozzles are noisy with water. If an inflatable nozzle is used, the effect will be both sculptural and quiet, such as a trumpet nozzle. B. wind interference. Some nozzles are influenced by external forces, such as semi-circular nozzles. The water film formed by this nozzle is so thin that it can hardly be formed under strong wind. It is worth mentioning that the ice tree sprinkler is hardly affected by its spraying effect. C. impact of water quality. Some sprinklers are greatly influenced by water quality, and the water quality is poor, which is easy to block, such as dandelion sprinklers, but some have little influence, such as spring water. D. height and pressure. All kinds of nozzles have their reasonable and effective injection heights. If you want to spray high on the side, you can use the central columnar nozzle, which is better than the DC nozzle, because the air in the middle of the annular water flow is thin and the surrounding air is tightly wrapped by the water column, which is difficult to disperse, and the children's paradise should choose the low-pressure nozzle for safety. E. dynamics of water posture. Most nozzles are installed or adjusted to spray in a fixed direction, such as DC nozzles, while some are dynamic, such as swinging and rotating nozzles. Under the action of machinery and water power, the movement of nozzles during spraying is specially designed, and some nozzles still follow the predetermined trajectory. Because of different designs, the same nozzle can spray various heights, and the stepless lateral velocity can make the spray trajectory curve even intermittent. The jet is in the form of dots, drops and strings, such as intermittent nozzles. Most nozzles are installed above the water surface, but foaming (foam) nozzles are installed below the water surface. Due to the fluctuation of the water surface, the posture of the sprayed water will fluctuate. When using this nozzle, you should also pay attention to the big waves in the pool.
