Abstract:
      Based on the test results of the hydraulic perform ance of the single sprinkler 30PSH, sets up the square form according to the combination coefficient such as 1.0R(range), 1.1R, 1.2R, 1.3R, studies the uniformity coefficient and different work pressure, and this paper puts forward that when designers make designs who should abide by the principle of low pressure and big combination distance which can be content with the uniformity and the lower cost when the wind power is very low even though without wind, i.e. designers should use the low pressure such 0.25 MPa, and the big combination coefficient such as 1.3R; the principle of low pressure and small combination distance which can be content with the uniformity and decrease the cost when the wind power is the first and second grade, i.e. designers should use the low pressure such 0.25 MPa, and the big combination coefficient such as 1.1R or 1.0R. while the project finished, under the condition of the uniformity, the manager can decrease the operation cost by adjusting the shifts and increasing or decreasing the opening valves to deal with the different wing power.
