Under simulated rainfall conditions, the IPX56 Test Chamber tests the physical and other related properties of the products. After testing, the results are assessed to determine whether the product meets the required standards, providing a basis for product design, improvement, verification, and factory inspection.
Rain Test Chamber Design Principle
A water tank is installed at the bottom. Water is pumped and pressurized by a stainless steel water pump inside the right-side control cabinet, then delivered to the spray nozzles on the side spray pipe system. The nozzle sprays water horizontally onto the sample placed on the turntable, and the water then flows back into the water tank, forming a water circulation system. The pump outlet is equipped with control components such as a flow meter, pressure gauge, and solenoid valve. A waterproof turntable is installed inside the inner chamber, and its rotation speed is controlled via the control panel.
