Repeatability excellent rain test chamber

Waterproof and Rain - proof Test Chamber。

1、 Structural characteristics

Cabinet material

The casing is generally made of high-quality stainless steel, such as SUS304 stainless steel. This material has good corrosion resistance, can adapt to long-term testing environments, and is easy to clean and maintain.

Spray system

The sprinkler system is a crucial component. It includes components such as nozzles, pipelines, and water pumps. The layout of the nozzle is reasonable and can simulate rainfall conditions evenly. For example, some test chambers adopt a multi-layer nozzle design, which can spray the test samples from different heights and angles to more comprehensively test the waterproof and rainproof performance of the samples.

There are various types of nozzles, commonly including fan-shaped nozzles and circular nozzles. The water sprayed by the fan-shaped nozzle spreads in a fan-shaped manner, covering a large area; A circular nozzle can generate concentrated water flow and is suitable for testing the waterproof performance of local areas of the sample.

2、 Working principle

Simulated rainfall pattern

Set parameters such as rainfall intensity (such as light rain, moderate rain, heavy rain, etc.), rainfall amount, rainfall duration, and spray angle through the control system. For example, in light rain mode, the water spraying speed is relatively slow and there is less rainfall; In heavy rain mode, the opposite is true.

The water pump extracts the water from the storage tank, transports it through the pipeline to the nozzle, and then sprays the sample placed in the test chamber according to the set mode.

environmental control

In addition to the sprinkler function, some advanced waterproof and rainproof test chambers can also control the temperature and humidity inside the test chamber. For example, in some special testing scenarios where it is necessary to simulate rainfall conditions in high temperature and high humidity environments, the temperature and humidity control system inside the test chamber will come into play.

3、 Application Fields

Automotive industry

The body of the car, components in the engine compartment, electronic devices, etc. all need to undergo waterproof and rainproof testing. For example, components such as windshield sealing strips, headlights, and onboard computers of cars can be tested in this test chamber to ensure that there will be no leakage or damage during actual use in rainy weather.

Electronic and electrical industry

Products such as mobile phones, tablets, outdoor lighting fixtures, and household appliances also need to undergo waterproof and rainproof performance testing. For example, mobile phones need to resist rainwater erosion to a certain extent to ensure data security and normal device operation when used outdoors.

construction industry

Some building materials such as door and window sealing strips, exterior wall decoration materials, etc. also need to undergo similar tests to ensure the waterproof performance of the building.

4、 Performance parameters

Rainfall intensity range

It is usually possible to simulate rainfall intensities ranging from 1-100mm/min or even wider to meet different standards and actual needs.

Test box size

The size of different models of test chambers varies, and the internal dimensions of small test chambers may be tens of centimeters square, suitable for testing small samples; Large test chambers can reach several meters in length, width, and height, and can accommodate large samples such as complete vehicles for testing.

control accuracy

The control accuracy of parameters such as rainfall intensity, temperature, and humidity is relatively high, for example, the control accuracy of rainfall intensity can reach ± 5%, and the temperature control accuracy is around ± 1 ℃.
