This Automatic Passenger Vehicle Rain Spray and Mist Test System is mainly compiled, designed and produced based on the vehicle form, vehicle size range, ground requirements and rain spray nozzle layout requirements provided by the user. Used to assess vehicles specified by customers. For example, the ability of doors, windows, opening covers and luggage compartments or cargo compartments of trucks and minibuses to prevent rainwater from entering the cabin. Verify its rain sealing performance.

By setting the spray rain detection conditions, the system can simulate the natural outdoor rain state. Conduct a spray test on the upper, lower, left, and right sides of the motor vehicle that may be exposed to rain. After the time specified in the standard, testers record and score based on the leakage conditions (seepage, slow drip, drip, fast drip, flow) of each part of the carriage. This will confirm the water sealing status of the outdoor car and implement structural improvements to possible leakage areas.

The system uses PLC intelligent central integrated control. Computer interface display and operation. Test data can be printed into reports. The report can be edited in the form of actual inspection report. Parameters are set through the computer interface. The spray test process is fully automated. It is the reliability equipment of choice for third-party testing agencies and factory laboratory departments.

During the rain test, the electronic control console sends a rain signal. The motor drives the water pump. The water in the clear pool is pumped into the pipe sprinkler system by a water pump. After pressure and flow adjustment, the system adjusts the rainfall that meets the standard requirements. The nozzle sprinkles water onto the surface of the specimen, and the specimen is subjected to a rain test. The sprayed water drips along the surface of the sample into the water tank at the bottom of the sample. Then collect and flow into the pond. After several times of filtration and sedimentation to remove impurities, it becomes clear water (note that clear water here means no impurities). Then it is pumped into the sprinkler system by the water pump. This is the use process of circulating waterway.

When performing a spray test, the solenoid valve is switched. The circulating water path enters the spray pipe and is sprayed onto the surface of the specimen from the spray nozzle.

The rainproof sealing test device of automobile windows must ensure that water is sprayed on the automobile windows from the side and top directions. Avoid dead spots for water spray. Ensure that the water spray pressure and flow rate correspond to each part of the car and meet the standard requirements. The frame structure of the rain room is simple and beautiful while ensuring rust resistance and shock resistance. The entire equipment is simple to operate and facilitates the inspection and maintenance of parts.
