What are the tips of fountain design?
In recent years, the application technology of fountain waterscape has developed rapidly, and many technologies have been widely used in practice. However, in some housing projects, the fountain waterscape is used more as a method of value-added and promotion. Its planning and construction do not consider long-term, thus laying a lot of danger. What are the tips of fountain design?
(1) Choose the water jet features you require as the types of nozzles depend on them.
(2) Determine the heights of the vertical jets. The choice of jet diameter and height depends on the artistic design of the fountain.
(3) Determine the falling distance for parabolic "solid" or "continuous" jets. That can be estimated for wind-free situations by using Spreadsheets.
(4) Use the technical manuals to ascertain that flow and pressure rates required to meet the design expectations.
(5) Consider organizing your fountain using groups or sets of nozzles.Grouping nozzles into sets that can be fed independently of each other enables the architectural fountain to work at a reduced level at times and on dates when there is less public presence. This helps to reduce operating costs and provides flexibility for maintenance.
(1) When the design calls for one or several basins of water in an architectural fountain, it is suggested that size them so that they also store the extra volume of water required to fill the piping and keep the jets and cascades working, thereby avoiding the need to build additional water tanks to ensure all parts function properly and also to prevent overflows when the fountain is out of service.
(2) Required water depth at the inlet to the pump suction pipes should be stated in the technical manuals supplied by the manufacturer of the pump. This will therefore prevent the inlet piping from becoming partially empty or whirls from being generated from which air could get into the pumps and lead to some malfunctioning or even cause the pumps to stop. As an additional measure, these areas should be protected by some type of semi rigid underwater grille to prevent unauthorized access.
(3) For safety reasons and especially to prevent accidents with small children, open fountain basins should be relatively shallow.
(4) A means of automatically re-filling the water tanks to compensate the volume of water lost through evaporation should be arranged as well as the water lost from the sprinkling effect of the nozzles and water carried away by wind.
(1) Water pump inlet piping should have a diameter of at least 1.5 to 2 times the diameter of the pump inlet.It is essential that an eccentric reducer is installed at the joint between the suction pipe and the pump inlet.This will prevent air building up at that point that would reduce the service diameter.It is equally important to avoid any head losses that might lead to excess under-pressure in the water flow going into the pumps so as to prevent cavitation.
(2) The diameter of the piping between the outlet from the water pumps and the point of delivery at the various nozzle sets is determined on the basis of economic speed.Economic speed is generally accepted to be between 1 and 1.8 m/s.
(3) The diameter of the sections of piping that house the nozzles depends on the design required for the water jets.For example, if the intention is that the water jets all reach the same height, the diameter needs to be calculated to ensure minimal head loss in each section of piping so that the pressure at the base of each successive nozzle does not differ significantly.
This depends on what use the area surrounding the architectural fountain has. For some outdoor fountains a quiet and soft flow of water or a discreet and staggered dripping sound helps, amongst other pleasant sensations, calm people down and urges them to stop and ponder or turn their attention to the feature with greater zeal. On the other hand, crashing water jets in wide-open areas grasp people's attention because of their magnificent visual appearance and the impact of their sound. In enclosed areas near offices and houses, the water sound of the garden fountain can be regarded as a kind of noise, which may interfere with life.
The use of lighting and music can help to highlight a water feature fountain. Lighting systems for water fountains generally comprise the following: lights, color filters, fastening systems for the lights and filters, wiring and a control panel. The latest generation of exterior and underwater lighting for water fountains uses LEDs, optic fiber and laser beams. Use of dance fountains or musical fountains with choreographies that combine water, music and color. Pay attention to keep the speed down to prevent causing damage or a disturbance to users, especially children.
In short, the design of the fountain should be designed according to the actual needs. Do not blindly pursue the appearance of exaggeration, and deviate from the actual use. It must be rationally laid out and comprehensively consider various factors. In the design process, it must consider environmental awareness, focus on energy conservation and environmental protection, and maximize water recycling.
