Test name: Pressurized pendulum pipe rain test
Test equipment: pendulum-type rain test
Sample placement: Choose a swing tube with an appropriate radius, make the height of the sample table at the diameter of the swing tube, place the sample on the sample table, and make the distance from the top to the sample water jet is not more than 200mm, and the sample table does not rotate.
Test conditions: The water flow is calculated according to the number of water spray holes in the swing pipe, and each hole is 0.6±0.5 L/min. The water spray area is the water spray from the water spray holes in the 90° arc segments on both sides of the midpoint of the pendulum tube sprayed to the sample. The sample to be tested is placed in the center of the semicircle of the pendulum tube. The swing tube swings 180° on both sides of the vertical line, about 360° in total. Each swing (2×360°) is about 12s.
Test pressure: 400kPa
Test time: the sample rotates 90° after the test for 5min
Note: The spray pipe has 121 holes with a diameter of 0.5mm;
— 1 hole in the center
— 2 layers of core area (12 holes per layer, 30 degree distribution)
— 4 outer circles (24 holes per circle, 15 degree distribution)
— removable cover
The spray pipe shall be made of copper-zinc alloy (brass).
