Method Name Water Spray Test
Test Method
. Swing tube type water spray test
Test equipment Swing tube type water splash test device
Place the sample and select a pendulum tube with an appropriate radius, so that the height of the sample table is at the diameter of the pendulum tube, and place the sample On the sample stage, make sure that the distance from the top to the sample water nozzle is no greater than 1, and the sample stage does not rotate.
Test conditions The water flow rate is calculated based on the number of water spray holes in the swing pipe. Each hole is /. When water is sprayed, the water spray holes in the arc sections on both sides of the midpoint of the swing pipe are sprayed towards the sample. The tested sample is placed in the center of the semicircle of the pendulum tube. The swing tube swings along both sides of the vertical line, totaling. Each swing is sprayed with water continuously for about
