This equipment mainly includes: spray system, filling water system, water cycle system, sewage system, electric control system, etc. 1. Equipment use l Mainly test the product under the condition of in the rain, prevent the rain infiltration capacity and have been in the rain or rain performance. l Check the Windows and sunroof installation is normal, sealed performance is reliable, the installation method is correct l Mainly used in the assessment of electrical and electronic products shell/seal after water test or during the test if you can guarantee that the equipment status and good work performance and component technology. At the same time or use of the transport process may be affected by flooding in, provides the reference basis for the product technical standard. 2. Applicable standards: QCT476-2007 Auto rain leakage test method 3. The design parameters l Equipment functions: used in car in the rain experiment. l In the rain intensity: the front to an average of 12 + 1 mm/min, after the two side and up and down, for the average 8 + / - 1 mm/min. l Power supply: AC 380 v three-phase plus or minus 5% 50 hz l Nozzle pressure: 150 kPa plus or minus 10 kPa l Application: suitable for auto side window detection and skylights water tightness, through in the rain, the outside in the rain test conditions and is similar to the state of nature, to confirm the water seal of the state of the equipment, to conduct a silicon waterproof may leak rain. l Pressure gauge: installed in the pump outlet pressure gauge, pressure: 0-0.5 MPa l Meter: installed after the pump export basins valve installation, flow: 0 to 25 m3 / h 4. The rain zone Get wet in the rain and reach a certain intensity by using jet injection surface of the window, ensure the water from the top side and direction to the car window, avoid water blind Angle, ensure water pressure and flow rate corresponding to each part of the car to meet the national standard requirements. Has a sewage treatment plant at the same time, the circulating water filtering processing, remove the mud sand and impurities, to the recycled water standards. In the rain room frame structure the welding and become, in ensure anti-rust, shockproof be neat and beautiful at the same time, the equipment operation is simple, easy to repair and maintenance of spare parts.
