IEC 60529 Vehicle Rain And Dry Test Room Rainproof Performance For Vehicle
Standards & Clauses:
Conforms to IEC 60529 Degrees of protection provided by enclosures (IP Code);
QC/T 476-2007 "Limits and test methods for rainproof sealing of passenger cars";
GB 29753-2013 "Safety requirements and test methods for refrigerated trucks for road transport of food and biological products";
QC/T 450-2010 "Technical conditions and test methods for insulated trucks and refrigerated trucks";
QC/T 453-2009 "Van transport trucks";
Rain test for refrigerated and insulated trucks: Close the doors and windows of van freight trucks reliably, with a rainfall intensity of 5 to 7 mm/min, a direction of 45 degrees to the plumb line, and a rainfall time of 30 minutes.
Purpose:
1. Test the ability of the tested product to prevent rainwater penetration and its rainproof performance during or after being rained on.
2. Check whether the windows and sunroof are installed normally, whether the sealing performance is reliable, and whether the installation method is correct
3. Assess whether the housing/seals of electrical and electronic products can ensure the good working performance and technical status of the equipment and components after or during the water test. At the same time, the product may be affected by water during transportation or use, providing a reference basis for product technical standards.
4. Add a blower and use a rain test with drying
Technical Parameters:
1. Equipment function: used for rain test of commercial vehicles.
2. Rain intensity: the average rain intensity of the side and top of the vehicle body is 5-12mm±1mm/min.
3. Power supply: AC three-phase 380V±5% 50Hz
4. Nozzle spray pressure: 69-150kPa±10 kPa
5. Purpose: suitable for testing the water tightness of the side windows and skylights of the central station of the car. Through the rain room, the conditions of the rain test are simulated to the natural state outside to confirm the water tightness of the car. Then implement silicone waterproofing on the parts that may leak.
6. Pressure gauge: install a pressure gauge at the outlet of the water pump, pressure: 0-0.5 MPa.
7. Flow meter: install a flow meter after the outlet flow regulating valve of the water pump, flow rate: 0-100m3/h
Design Concept:
1. Take advanced, reliable, economical and practical as the principle. We fully consider the characteristics of the product and actively adopt advanced and mature processes and equipment. Improve the complete set of water sealing detection capabilities so that this indicator meets the specified technical requirements and enhances the market competitiveness of the product.
2. Reasonable layout and smooth logistics are achieved in the design, and attention is paid to energy-saving measures of equipment and rational use of energy.
3. Implement national policies and regulations on environmental protection and labor safety and health. The entire project meets the national "three wastes" emission standards and industrial hygiene standards.
4. The selection of equipment and materials is mainly domestic, achieving the purpose of being both economical and reasonable, advanced and reliable.
Process Specification:
This shower room is mainly used to test the water tightness of the car. The water tightness of the car is confirmed by simulating the natural state outside.
Shower area: The window surface is sprayed with a certain shower intensity. At the same time, a sewage treatment device is installed to filter the circulating water, remove mud, sand and impurities, and make it meet the standards for recycled water. The frame structure of the shower room is welded on site.
Use Environment:
Power supply: AC380V±5%, 50Hz, or meet with client's local power supply requirements.
Use place: temperature 15-35 ° C, relative humidity 25%-75%, atmospheric pressure 86 ~ 106kpa (860 mbar -1060 mbar), the ground needs to be flat, with lighting, with waterproof leakage proof switch (or socket), the water intake and drainage conditions should be good
Water source: clean water or tap water without impurities, water cleaning filter should be equipped
