Test Chamber

 Applied Standards

 
QC/T476-2007 “Rain Proof Performance Limit and Test Method for Bus”: Water emerges from gaps, leaves or runs continuously down the interior surface of the vehicle
 
QC/T449—2010 “Technical Conditions and Test Methods of Insulated and Refrigerated Vehicles” clause 4.15
 
It is used to test the rain proof performance and anti-seepage ability of the vehicles, and to check whether the vehicle window and sunroof are installed properly, whether the sealing performances are reliable, whether the installation methods are correct, to evaluate the rain proof performance of the whole vehicle.
 
It is suitable for testing the waterproof and sealing performance of outdoor motor vehicles. Through the raining test system, the conditions of rain test room are similar to the natural state outside, to confirm the water sealing state of the vehicle, and to improve the structure of the parts that may leak.
 
The system consists of a rain room, a spray system, a water supply system, a water circulation system, a sewage system, an electronic control system, and movable spray plates.
Rain area: the surface of the vehicle window is sprayed under a certain rain intensity. A sewage treatment device is installed, the circulating water is sent to the sewage pool for filtration treatment, and then filtered again by the clear water tank to make it is recycled. The frame structure of the rain room is welded on site.
The reservoir and drainage system in the test room should be completed by client.

Questions & Answers

Q: How about the nozzle?

A: 1. The nozzle adopts PP material nozzle. The spray state is solid conical, the water spray angle is 60°, the top nozzle is vertical to the horizontal plane, and the nozzle design conforms to the national standard. The nozzles are in a square array, and there is no blank area in the spray area. The nozzle can be adjusted appropriately according to the spray angle. According to the design basis, four sides of the water nozzles are arranged in the shower room, and the horizontal and vertical spacing of the nozzles is 400mm.

2. The nozzle and the ball seat are threadedly connected, and the ball seat machine is stuck on the water pipe, which is convenient for replacement and cleaning of blocked impurities.
