Waterproof Test Machine

Structure and Advantages of Waterproof Test Chamber

LIB waterproof test machine is designed to simulate different levels of dripping, spraying and splashing in order to assess the water resistance of the product. 

1. Waterproof test machine body: Made of solid material SUS304 stainless steel, all welded surfaces and cross-sectional surfaces are pickled to prevent rust and ensure durability and stability.

2. Drip device: Used for IPX1 and IPX2 tests, usually including drip tray, drip hole and adjustment device to control the speed and amount of drip. The size of the drip tray depends on the size of the test chamber. IPX1 and IPX2 have water flow rates of 1ml/min and 3ml/min, respectively.

3. Oscillating tube: used in IPX3 and IPX4 tests, consisting of a rotary pipe with a water jet hole distributed above. The motor drives the oscillating tube to swing to realize water spraying at different angles. Oscillating tube size is 200mm, 400mm, 600mm, 800mm, 1000mm, 1200mm, 1400mm, 1600mm optional, the number of nozzles depends on the radius of the oscillating tube. The nozzle spacing is 50mm and the nozzle diameter is φ0.4mm.

4. Sample fixing device: used to fix the sample to be tested to ensure its stable position during the test and prevent it from being washed away by water. There is a waterproof power supply device on the turntable to energize the test part and restore the most realistic test conditions. The height of the turntable for IPX1 and IPX2 tests is 350~500mm and can be adjusted. The turntable is equipped with a 15-degree tilt dial for IPX2 testing, which is removed when IPX1 is performed.In the IPX3 and IPX4 tests, the turntable speed is 1 RPM, and the turntable height is 350~500mm, which is adjustable.

5. Water circulation and treatment system: including water tank, pump, filter, etc., to provide clean water and achieve water recycling. LIB specially designed a set of automatic inlet filtration system to filter impurities in 0.03mm particles, which ensures the smooth flow of the spray system.

6. Control system: PID intelligent touchable system, test parameters can be set, such as oscillating angle, speed, water time, etc., and real-time display and monitoring of the test status, test data can be exported.

Specifications of Waterproof Test Machine

How Waterproof Test Machine Works:

The waterproof test machine is a specialized device used to evaluate the waterproof performance of products, and its working principle is based on the precise simulation of different levels of dripping, drenching and splashing. Through a series of carefully designed devices and control systems, standardized water contact tests are performed on test samples to determine whether the water resistance of the sample meets the corresponding IPX1, IPX2, IPX3, IPX4 class requirements.

 1. IPX1 test: The sample is placed on turntable with the fixed device, the drip box starts to work, and the water drops vertically through the drip hole at a specific speed to the sample surface. By adjusting the drip box, the drip amount and drip time are controlled to simulate the environment of slight dripping.

2. IPX2 test: similar to IPX1, but the sample needs to be placed at a tilt, usually at a tilt angle of 15°, and the drip device is still dripping vertically, so that the water droplets fall on the sample at a certain tilt angle.

3. IPX3 test: The oscillating tube is used to spray water, and the oscillating tube is driven by the motor to swing. Water is sprayed from the blowhole on the oscillating tube to create a rain effect, spraying the sample in all directions. By adjusting the swing angle, speed and water flow of the oscillating tube, the different intensity of the water is simulated.

4. IPX4 test: On the basis of IPX3, further increase the strength and range of water injection. The swing tube's blowhole may be smaller, with greater spray pressure, or the number of sprinklers may be increased to impact the sample with a more intense and widespread stream of water.

During the test, the water circulation system continuously sends water back to the tank, which is filtered and treated again for testing to save water and keep the water quality clean. The control system accurately controls each test parameter and monitors the test status in real time to ensure the accuracy and repeatability of the test.

After the test is completed, according to the performance of the sample, such as whether there is water, leakage, etc., to determine whether the waterproof performance of the product meets the corresponding IP waterproof grade requirements.
