After several months of negotiations, we determined the technical parameters of the final version of the Passenger Van Transport Vehicle Rain Test System with the American customer!

The test purpose of this test system is mainly the ability of the product to prevent rainwater penetration and the rainproof performance when or after being exposed to rain under the condition of rain.

Check whether the assembly of the body, doors, windows and sunroof is normal, whether the sealing performance is reliable, and whether the installation method is correct

This test system is mainly used for the rainproof and sealing performance of various types of passenger cars and vans.

This system meets the standard QC/T 476-2007 "Rainproof Sealing Limits and Test Methods for Passenger Cars", and adapt to the standard GB 29753-2013 “Safety Requirements and Test Methods for Refrigerated Vehicles for Road Transport of Food and Biological Products”, QC/T 450-2010 "Technical Conditions and Test Methods for Insulated Vehicles and Refrigerated Vehicles" and QC/T 453-2009 "Van Transport Vehicles".

Rain test for refrigerated and insulated vehicles: The rain test is carried out in a specially designed rain room, the rainfall intensity is 5-7mm/min, and the direction is at an angle of 45 degrees to the vertical. The rain test is carried out for 30 minutes on all the compartments, etc., the artificial rainfall test of the rain test system, the doors and windows of the van are reliably closed, the rainfall intensity is 5-7 mm/min, the direction is at an angle of 45 degrees to the vertical, and the rainfall time is 30 minutes.

Technical Parameters

1. Equipment function: used for the rain test of automobiles. The external dimensions of the applicable vehicle range from 3500×1400×1400mm to 13700×2600×4200mm.

2. Rain intensity: the average of the front is 7~12±1mm/min, and the average of both sides, upper, lower and rear is 7~8±1mm/min. The rain intensity of each part can be adjusted.

3. Power supply: AC three-phase five-wire 380V±5% 50Hz

▲4. Nozzle injection pressure: 150kPa±10kPa

5. Pressure gauge: install a pressure gauge at the outlet of the water pump, pressure: 0~0.5MPa.

6. Flowmeter: Install a total electromagnetic flowmeter after the self-flushing filter at the outlet of the water pump. The total flow rate is 0-150m3/h. The branch pipe adopts a visual flowmeter and is installed after the flow regulating valve.

7. Rain time: 1 ~ 60min.

8. Outline dimensions of the frame of the rain detection room (length × width × height): about 15000×5200×6000mm.3.9. The rain detection room is an outdoor skeleton type, without a roof and surrounding protective panels. The frame reserves the interface and space for building a canopy in the future.
