Rain test program for passenger cars


Project purpose

Detect the ability of the car body shell to prevent rainwater penetration under rain conditions and the rainproof performance when or after being exposed to rain. It is mainly to check whether the car windows and sunroof are installed properly, whether the sealing performance of the car body gap is reliable, whether the installation method is correct, etc.


An Introduction

According to QCT476-2007 "Test Method for Rainproof and Sealing of Passenger Cars", the program adopts spraying method and reaches a certain rain intensity to spray the surface of the window. Through the rain room, the rain detection conditions are similar to the natural state outside. Check the water-tight state of the car.

Rain Test Room for Passenger Cars - Scheme Reference Diagram


[Water spray pipe] All spray pipe materials are made of stainless steel 304# water pipe; the inner diameter of the water pump suction pipe is 80mm, and the water supply main pipe diameter of the water pump: the top diameter is 80mm; the two sides water supply: the main pipe diameter is 80mm from the pump outlet to the bottom of the flowmeter.

[Nozzle layout] According to the design basis, 6 spray nozzles are arranged in the rain shower room. The horizontal and vertical spacing of the nozzles is 400mm. There are a total of 528 nozzles, including 144 nozzles on the top and 168 nozzles on the left side. ; 168 sprinkler nozzles on the right side; 24 sprinkler nozzles on the front; 24 sprinkler nozzles at the tail (the distance of the tail can be adjusted); 60 sprinklers at the bottom (the bottom spray can be controlled separately).

[Filtration device] The reservoir is divided into three areas: the first sedimentation reservoir, the second sedimentation reservoir and the clean water reservoir. There is a partition wall between the first sedimentation reservoir and the second sedimentation reservoir. There is a square hole in the middle of the wall, and there is a filter screen between the second sedimentation reservoir and the clean water reservoir. The water quality after adjustment is ≤300μ, and the filter can be easily removed and washed. The spray water is provided by the clean water reservoir, and the capacity of the reservoir should meet the requirements of the entire spray system.

[Rotation system] The front revolving structure, the revolving stroke left and right each forward 90 degrees, adopts electric revolving structure.

[Control system] The device includes a manual console, a remote remote control, and a LCD touch screen output, which can realize three control modes: manual, remote remote control and automatic.

[Protection device] The equipment is grounded as a whole, and the control system is also set with various protection functions, including leakage protection, water pump failure alarm protection, automatic water filling of the pool and water shortage alarm protection, etc., perfect protection functions to ensure rain The room can run stably and trouble-free for a long time, has multiple protection functions, and is safe and reliable.


Solution value

The rain test room program for passenger cars is designed according to the size of the passenger car, which can completely spray the whole passenger car from all directions. The test results are more complete and the results are more realistic. This plays an important role in the quality inspection of automobile companies before leaving the factory. It can reduce the defective rate of products and avoid the loss of brand image caused to the enterprise in the later period. This rain test room includes a circulating filter spray function, which can ensure the speed of rain detection and speed up the detection efficiency. With the addition of the remote control function, the driver can drive the car to the entrance to turn on the spray switch, which is simple and convenient to operate and reduces the amount of water used for spraying.
