Abstract：Comparing with common micro-sprinklers,the micro-sprinkler over 5 m range has the advantages of decreasing cost,lowering irrigation intensity and reducing water usage,etc.It was invented in(China),using stream′s lean-wall principle in micro-sprinkler.The developed micro-fluidic-sprinkler WPXS300-300,whose stream jetting part works as both the exit part and the rotation driving part,has a nozzle of 2.5 mm and a range of over 5 m.It has a simple structure and reliable function.By testing the water distribution,relation between pressure and flux,and between pressure and range for the developed sprinkler can meet the standard of micro-sprinkler.
