2、 Design Introduction：

1. This waterproof test box is mainly used to evaluate the product shell/Can the sealing components ensure good working performance and technical condition of the equipment and components after or during the water test. At the same time, the product may be affected by water immersion during transportation and use, providing reference for product technical standards.

2. It is suitable for artificial rain tests based on natural conditions, without rainfall with strong wind speed, and without considering the high temperature of the sample and the large amount of water inflow caused by the temperature difference of rainwater.

3、 Structure and Material

1Box material: All areSUS304Made of stainless steel plate, the workshop or other parts that come into contact with water are made of stainless steel plate or copper material.

2Water pump: provides a pressurized test water source

3. Flow meter: Water flow measurement

4. Door: Large screen visualization door for real-time observation of experimental conditions

5Deceleration mechanism: speed regulating motor,OM，90W/100W

6Swing tube swing: through motor/Variable frequency drive（schneider）Drive reducer/eccentric mechanism/Mechanical transmission such as rack and pinion gears is implemented. Use a frequency converter to adjust the required angle (per unit time) through an eccentric mechanism.

7Rotating worktable: The tabletop isPVCThe hard plate (corrosion-resistant plate) motor drives the worm gear reducer to rotate, and the frequency converter is used to adjust the speed to the appropriate level. It can rotate forward and backward, with adjustable time and speed.

8. Nozzle: The bending radius of the swing tube is determined by the size of the specimen and the internal volume of the box. The nozzle is a foldable specialized nozzle, and the spray hole can be replaced at any time according to the standard required aperture. The spray direction can be adjusted to ensure that the water droplets are evenly sprayed and the flow rate is sufficient

9. Water supply tank: stainless steel water storage tank, low water level protection, drainage valve,

10. Sewer: Designed to quickly drain at the bottom of the box without accumulating water.

11. Reserve external cable interfaces.

4、 Technical documentation and attachments provided

Provide a set of relevant documents such as product certification, warranty card, user manual, and instrument manual

5、 Packaging and transportation methods
1. Packaging method: wooden crate2Transportation method: Automobile transportation
