Fountain company in the square fountain planning skills
Fountain was originally a natural landscape, is the pressure water outgrowth on the ground, but now the fountain is mostly for the needs of landscape and create decorative artificial fountain. It not only has rich and gorgeous water, but also can be combined with music, colorful lighting. This paper introduces the fountain planning techniques.
One, seek beautiful, settle the structure of fountainhead and inside conduit
1. Plan the structure of the fountain according to the general requirements
The commonest practice is: make pool wall tower above the ground, such pool wall can use store water, make pool wall top the small cantilever eaves that tower above water surface together, can sit a person so. Other, when the water spray waves or blowing strong wind, can make the water is not simple splash pool. The water tray in the fountain can plan various tricks and methods according to the needs of artistic construction. There are three basic methods: hole overflow type, overflow weir type and combination type.
2. Seek for beauty and plan pipes in the fountain
When planning nozzle piping, it is necessary to consider the beautiful shape of spray nozzle. Generally consider straight nozzle, straight pipe section to have 20~50 times the length of nozzle diameter, of course, can not have a sharp turn of this situation. If need, can set rectifier in the pipe section before sprinkler head interior, make the compactness of gushing water column is better. If must set for broken line section or annular section, requirement current rate cannot exceed 0.5~0.6m/s commonly, ability ensures the inclination of nozzle, had better choose a direction to use adjustable nozzle at this moment. In addition, the distribution pipe should be arranged in a branch or ring according to the pattern. It is necessary for pipe joints to be lubricated and tight, the elbow with large turning radius should also be used at the corner, and the reducer pipe should be used outside the transformer.
2, down-to-earth, planning fountain appreciation orientation, modeling and fountain scale 1, down-to-earth, planning fountain appreciation orientation, modeling
Should be based on local conditions and the construction of the art of induction requirements to determine the fountain appreciation orientation, shape size. Take the primary appreciation address as the center, the first consideration in the flower pattern conception, considers the sprinkler head modelling quantity how many, the azimuth is suitable and the underwater lamp settlement, then proposes the appropriate sprinkler posture change plan and the appropriate water quantity, the hydraulic press control method request, makes the flower pattern becomes orderly, the light and the dark alternate with each other.
2, according to the demand, the decision of the size of the fountain
In general, the radius of the pool is not less than the height of the spray. The depth of the fountain shall generally be in accordance with the sprinkler equipment needs, generally speaking, spray pool depth is more shallow, when emptying the water demand in water is small, but if spray pool depth is too shallow, in the sunlight, algae, simple and agile, so demand into a certain amount of chemicals to avoid the growth of algae. If need equipment underwater lamp, the optimal interval that underwater lamp leaves water surface is 60mm left and right sides, depth of pool is 60mm commonly, if conduit demand is put hierarchically, should decide depth according to actual demand.
Iii. Convenience orientation and other equipment setting
1, easy to clean, set the overflow of the fountain drainage and supply equipment overflow equipment Settings should pay attention to do not affect beautiful, and easy to clean and dredge, overflow mouth should be set in front of the grille, in order to prevent floating objects blocking the pipeline, grille gap should not be greater than 1/4 of the drainage pipe diameter. The primary function of the drainage equipment is to facilitate cleaning, if you want to overhaul or stop the operation of the fountain, the water should be empty. General drainage methods are pressure type and gravity type. If choose when circulating water system, cistern discharge water mouth can be used with water pump suction mouth, use water pump drainage air defense. Grille should be installed on the sump and cover the filter screen to prevent the drain pipe and circulation pump from blocking.
2. According to different requirements, there are two ways to change the flow profile of the fountain and control the flow profile of the fountain: one is to control the start and stop of multiple pumps. This method can ensure that in addition to the operation of the water pump is spraying, other pumps do not work, according to the required head separation pump, save pipe, less power consumption, but pump stop frequently, easy to damage the equipment. The second is to install the control valve between the water pump outlet pipe and the sprinkler head, that is, to use a pump to control the sprinkler head of multiple systems, to use the control valve to change the operation of the sprinkler head system, and to use a pump to complete the sprinkler head system near the water volume and hydraulic pressure root. And be careful not to disturb the flow of water from each nozzle system.
3. Pay attention to the reasonable use of water pumping equipment and lighting equipment
Water spraying is generally equipped with a pump, commonly used for horizontal centrifugal pump and submersible pump, submersible pump is selected to be placed directly in the pool or deeper sump, and the grid cover, the area of the water filter should not be less than 5mm. Large fountains can be selected together with these two pumps to meet the different requirements. If the submersible pump local water supply can be adapted to a single sprinkler head away from the pump water supply area, and centrifugal pump for other sprinkler head. When choosing centrifugal pump, should build semi-underground type or underground type pump room, azimuth also should be set in pool as far as possible inconspicuous local or green ground limits. Of course, the interval pool cannot exceed 25m at the most, considering the ventilation, drainage and other problems of the pump room. The maximum planning flow rate of the water pump suction pipe is 0.3m/s. When equipping pipelines and valves, attention should be paid to the proper height and reasonable use space of kongshan pump room, as well as the emptying method of water in pipelines.
