Abstract: Based on the analysis of the H-Q characteristics of the sprinkler pump, the pressure loss of the pipeline and the flow characteristics at the outlet of the sprinkler, the calculation method of the sprinkler performance is established by combining the hydrodynamics theory and parabolic motion theory. By comparing with the experimental data, it is verified that the calculation method of sprinkler performance established in this paper has high accuracy, and has a certain practical engineering application value.
