A. Swing tube type water spray test Test equipment: Swing tube type water spray test device (see figure 2.14 of this book for device graphics and test methods)
Sample placement: Select a swing tube of appropriate radius so that the height of the sample table is at the diameter of the swing tube. Place the sample on the sample table so that the distance from the top of the sample to the sample spout is not greater than 200mm, and the sample table does not rotate.
Test condition: The water flow is calculated according to the number of spray holes of the pendulum tube, and each hole is 0.07 L / min. When spraying water, spray water from the spray holes in the 60 ° arcs on both sides of the midpoint of the pendulum tube to the sample. The test sample is placed in the center of the semicircle of the pendulum tube. The pendulum tube swings 60 ° on both sides of the vertical line for a total of 120 °. Each swing (2 × 120 °) takes about 4s.
Test time: continuous watering for 10 min.
B. Sprinkler type water spray test Test equipment: hand-held water spray test device, device graphics and test methods are shown in this book 2.14
Sample placement: make the parallel distance between the top of the test and the nozzle of the hand-held nozzle between 300mm and 500mm Test conditions: a baffle with a counterweight should be installed during the test, and the water flow rate is 10 L / min
