Research on A New Kind of Fluidic Sprinkler

摘要

The fluidic sprinkler is a kind of sprinkler with an output part not only discharging water, but also controlling the forward, backward and step moving of the sprinkler. The sprinkler structure is simple, because it replaces the complex driving device with a simple fluidic component. The performance of fluidic sprinkler is compared with that of common impact sprinkler. As a result, the sprinkler range of fluidic sprinkler is hardly reduced, and some performances, such as distribution uniformity, size of water droplet and mist degree are superior to those of impact sprinkler. The constructions of fluidic sprinkler are summarized in this paper. Complete fluidic sprinkler is developed from feedback fluidic sprinkler, which avoid the sensitivity of structure sizes. The working principle and characteristics of complete fluidic sprinkler are introduced. Because of the simple structure and excellent performance, it is necessary to have a further research on the fluidic sprinkler. The research should consider both the internal and external properties, and finally get its optimal design for multiple objectives and multiple constraints.
