The main purpose of this laboratory test is to evaluate the ability of the tested product to prevent rainwater infiltration and its rainproof performance during or after exposure to rain Whether the roof and sides of military vehicles, small cars, and agricultural vehicles can withstand rainwater spray, whether the sealing performance is reliable, and whether the installation method is correct. Can the casing/sealing components of electrical and electronic products ensure good working performance and technical condition of the equipment and components after or during the water test

This device is pre designed with a return water tank in the water channel before flowing into the water supply tank, and an additional filter screen is added to filter out debris such as tape and paper entering the reservoir. A second stainless steel filter screen is installed at the inlet of the reservoir to prevent debris from entering the sewage pump of the reservoir through dual filtration. The design of the filter screen should also consider the convenience of cleaning garbage. A stainless steel filter screen should be added to the suction tank in the main pump area of the sedimentation tank, and the circulating water should be filtered before use, with a filtration level of 500um.
