Effects of complete fluidic sprinkler on hydraulic characteristics based on some important geometrical parameters

As an important part of the irrigation devices, sprinkler headinfluences the efficiency of sprinkler irrigation directly. A new kind of　complete fluidic sprinkler is put forward in this paper. It points out the effectsof complete fluidic sprinkler on hydraulic characteristics based on the change of geometrical parameters. The theoretical analysis is testified by the experiments. There is a good agreement between them. The important geometric parameters include depth of signal flow, gap C，length of pipe, dimension of potential difference, length of working area andso on. The working condition of the sample sprinkler is reliable. And the paperput forward the best parameters of the sample sprinkler.
