Research On Siphon Type Automatic Surge Flow Water-Saving Irrigation Equipment

This subject adopts a new type of green irrigation—surge flow of ground water saving irrigation technology. It has many advantages such as water saving(than ordinary ditch, border irrigation and other irrigations saving 10% ~ 40% water), energy saving, fertilizer protecting, uniform production, irrigation uniformity, water quality and water speed, reduce deep leakage, reduce the labor intensity, reduce the cost of agriculture; What's more,available turbidity water, salt water or sewage irrigation can beused in the green irrigation technology. And we don't need afford extra water purification treatment. The irrigation operation is simple, easy to manage and doesn't need to have certain professional knowledge management. In a word, surge flow irrigation is a very suitable for China's national conditions of water saving irrigation methods.Can design a canal water for the power, to realize automatic surge flow irrigation water-saving irrigation equipment, is the important measure to promote the development of surge flow water saving irrigation technology and is the surge flow irrigation necessary for large area to promote water-saving irrigation technology and its application. This topic according to the experience of the water-saving irrigation field wave flow and surge flow irrigation technical parameters requirements, determine the good irrigation schemes, and use the irrigation scheme for preliminary design of the plant. Under the condition of water channels, siphon channel automatic surge flow irrigation automatic equipment, using the waterwheel lifting water as power, through the regulator pool and the control pool(playing the role of timer) and other components control siphon timing forming siphon or disconnect the siphon, accomplishing surge flow water saving irrigation cycle of water and water supply, and achieving automation of surge flow irrigation. The siphon automatic surge flow water saving irrigation device has the advantages of simple operation, easy to use, no additional power, and can realize the cycle water irrigation time, cycle time, the circulation rate, irrigation flow various wave flow stepless regulation of irrigation parameters, and has the province, energy saving, energy saving, convenient use, etc.On this topic in canal irrigation district channel automatic wave flow field under the condition of ground water saving irrigation technology and its automatic irrigation device as the research object, in order to solve the problem for efficient irrigation and irrigation automation field goal, the experimental study and theoretical analysis, the method of combining study of powered by canal irrigation water field siphon type automatic wave flow of ground water saving irrigation technology. Discusses the application of its corresponding pattern, establishes the index system of its technology, formulate corresponding irrigation system, field irrigation technical parameters of standards, strict control of irrigation parameters, better able to control water quality, raise the utilization ratio of irrigation water. This topic research for saving water, alleviate the water shortage situation, has the important practical significance and broad prospects for development. At the same time,research by canal irrigation water power field siphon type automatic flow of ground water saving irrigation technology, favorable flow wavelengths, popularization and application of water-saving irrigation technology and ground automate field ground water saving irrigation, provide effective technical support for the majority of irrigation district, has a broad development prospect and important practical significance.
