Artificial falls under the condition of the pump selection

Waterfall with a submersible pump, head to determine the height of the waterfall, flow determines the size of the waterfall. Of course, can be selected according to the site conditions of the flow and head of the centrifugal pump.
The basic structure is composed of artificial waterfall waterfall water reservoir, water weir, waterfall bottom lining, waterfall waterfall pool or body, bearing a circulating water tank, circulating pump, water purification equipment, circulation pipeline system and lighting lights and other components, as shown in Figure 2 2-4.

The difference between the water drop height or call drop, see Figure 2 in 2-4 H.
1 water tanks
Artificial waterfall size depends on the size of the falls reservoir. By the use of circulating water, the water storage volume is relatively small, the smaller waterfall, the circulation pipe wear alone L tube as the water falls.
2 weir mouth
The main form of the weir mouth is wide crest weir. Can be divided into natural waterfall fall into the water, the rules of the mouth of the weir and the twists and turns of the weir. No matter what form of the weir mouth, must be strictly level.
3 waterfall bottom lining
Falls from the mouth of the weir overflow, followed by the bottom line of the waterfall. The material of the waterfall bottom lining can be made of concrete, granite, glass curtain wall or stone. In order to make the water flow more dynamic, the refraction of light and the change of the shape of the water, the bottom lining of the waterfall can be made into a broken line shape, and a rough concave and convex; or a convex block is inlaid on the bottom lining. According to the stone play different roles, known as the mirror refraction of light stone, stone, water diversion cutting flow and broken stones and a falling water and meet the ultra energy dissipation effect of bearing waterfall stone.
4 waterfall body
The water formed from the water weir overflow water called Waterfall body. The waterfall was drowning weir shape and the influence of different substrates to form different waterfall, waterfall body form in the dropping process.
5 bearing waterfall pool
The waterfall is specially called Waterfall recycling pool.
The waterfall pool is the role of the whereabouts of the waterfall of water, and the energy dissipation effect; the waterfall formed reflection, abundant water, enhanced momentum. In the waterfall pool can be concealed lighting lights, circulating water pumps and water pipes.
6 circulating water pump and circulating water pipe system
The water must be recycled artificial waterfalls, circulating water pump submersible pump commonly used directly mounted on the bearing hidden waterfall pool towel. Flow and lift submersible pump to the hydraulic calculation, the waterfall flow and drop height to meet the needs of.
The circulating pipeline system comprises a water delivery pipe and a perforated pipe. The perforated pipe in the water tank of concealed laying, perforated pipe length equal to the width of the LJ weir.
7 water purification equipment
Falls in the process of recycling, by light or sunlight, dust, impurities, ground base materials such as pollution, the main pollutants are inorganic algae, suspended solids and bacteria, need regular cleaning treatment and disinfection.
8 lighting lanterns
Lighting lanterns are mounted on the bearing of the hidden waterfall pool below the surface, for night lighting, the rich and colorful waterfall.
