program purpose

The water sealing performance of the vehicle body mainly assesses the vehicle's ability to prevent water from entering the passenger compartment and luggage compartment when the doors, windows and hole covers are closed in rainy days and car wash environments, which is the most basic requirement for automotive airtightness. Leakage points are generally manifested in poor sealing of the windshield, poor sealing of the wire harness sheath, poor sealing of the rubber strip, poor sealing of the threaded connection, stamping defects, and welding deformation. Through the vehicle rain test room, the waterproof performance of the vehicle can be tested in an all-round way .

An Introduction

The rain shower room is mainly used to test the water tightness of the car. Through the rain shower room, the conditions of the rain test are similar to the natural state outside to confirm the water tightness of the car. This equipment mainly includes: side and top, bottom spraying system, water supply system, water circulation system, sewage system, electric control system, top up and down lifting, etc. It can meet the test standards such as "QCT 476-2007 Passenger Car Rainproof Sealability Limits and Test Methods".

[Main pipes] All spray pipes are made of stainless steel pipes; the inner diameter of the water pump suction pipe is 63mm, the top of the water supply main diameter of the pump is 63mm, and the main diameter from the pump outlet to the bottom of the flowmeter is 63mm.

【Water Sprinkler Nozzle】Adopts an adjustable plastic nozzle. The spray state is solid conical, and the cone angle is 60 degrees. Spraying angle, the top nozzle is perpendicular to the horizontal plane, and the nozzle design conforms to the national standard. The nozzles are arranged in a square grid, and there is no blank area in the spray area. The nozzle can be properly adjusted according to the spray angle.

[Filtration device] Two layers of filter devices are installed in the pool, which can effectively filter the impurities in the circulating water of the circulating pool, reduce the clogging of the nozzles, and ensure the normal operation of the system

[Control system] PLC control + control panel control and remote remote control are adopted, equipped with electric parameter meter, with power-off data storage function and alarm prompt

[Automatic water replenishment] In order to replenish water to the pool in time, a water replenishment system is specially designed. The water replenishment system is composed of water inlet pipe, solenoid valve, water level switch, ball valve and so on. The automatic operation of water replenishment in the circulating pool reduces the workload and enhances the stability of the system operation.

program value

This set of solutions is suitable for the rain test of small cars, and has a clear structure and is easy to maintain. The four-sided water spray scheme plays an important role in the quality inspection of automobile companies before leaving the factory. It can reduce the defect rate of products and avoid the loss of brand image caused by the company in the later stage. This set of rain test room includes a circulating filter spray function, which can ensure the speed of rain detection and speed up the detection efficiency. Adding 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 also reduces the water consumption of spraying.
