IP4 Rain Testing Machine

Product Design:
1. Box material: All are made of SUS304 stainless steel plate, and the working room or other parts that come into contact with water are made of stainless steel plate or copper material.
2. Water pump: provides a pressurized test water source
3. Flow meter: Water flow measurement
4. Door: Large screen visual tempered glass door, allowing for real-time observation of test conditions
5. Reduction mechanism: worm gear reducer
6. Swing tube swing: It is achieved through mechanical transmission such as motor/frequency converter driven reducer/eccentric wheel mechanism/rack and pinion gear. Use a frequency converter to adjust the required angle (per unit time) through an eccentric mechanism.
7. Rotating worktable: The tabletop is made of PVC hard board (corrosion-resistant board), and the motor drives the worm gear reducer to rotate. The speed is adjusted using a frequency converter to adjust the appropriate 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, equipped with water quality filter, inlet float ball valve, drain valve. If heating is required, electric heating pipes and temperature controllers can also be installed in the water tank.
10. Sewer: Designed to quickly drain at the bottom of the box without accumulating water
Technical Specifications:
1. Studio size (mm): (600 × 600 × 600) (width × depth × height)
2. Nozzle material: SUS304 stainless steel material;
3. Spray hole diameter: ￠ 0.4mm
4. Spray hole spacing: 50mm;
5. Spray pipe diameter: φ 16mm;
6. Spray ring radius: R375mm;
7. Adjustable nozzle angle: 120 degrees (IPX3), 180 degrees (IPX4).
8. Water pressure bar: adjustable water flow rate according to regulations
9. Test product distance: 100mm to 600mm;
10. The rotation speed of the stage can be adjusted (0.7-5 revolutions per minute)
11. Flow rate: 1-7L/min;
12. Airflow velocity 1.0m/s (adjustable water flow velocity)
13. Pressure gauge: 1 piece, water pressure in rain is about 80-100KPa
14. Test time: 0-999min adjustable control
15. Swing angle amplitude: ± 45 °, ± 60 °, ± 90 °, ± 180 ° (adjustable);
16. After the experiment is completed, the accumulated water in the water pipe can be automatically drained.
17. The swing tube is driven by a servo motor, with high precision and accurate time and swing amplitude.
18. Water supply pipeline: PPR pipes are used for equipment water supply and arranged according to the box distribution, controlled by the equipment control system cabinet.
19. Heating method: stainless steel heating tube is used, and the surface of the shallow water plate evaporates;
20. The spray cycle inside the box is adjustable, and the box door is equipped with an observation window to observe the status of the samples inside the box. Window wiper equipment usage environment:
1. There is no strong vibration, high concentration dust, or corrosive substances in the surrounding environment
2. There is no strong airflow around, and the installation site is well ventilated
3. The test chamber should be placed steadily and kept level
Control system:
1. Adopting Korean TEMI color screen touch screen temperature programmable controller, with multi-stage program control operation. Can adjust the impact of rain and dust products on the test at RT+5~50 ℃
2. Parameter settings are simple and do not require entering the program menu. You can directly enter the parameter menu to modify.
3. The total time of the experiment can be controlled, and the interval time and vibration period of the rain can be adjusted.

Suitable for rain, dust, and sand immersion testing of various industrial electronic products such as automotive parts and electronic appliances. Automotive parts include testing the fully sealed stability of systems such as car lights, door locks, electrical systems, instruments, dust covers, and electronic household appliances. The tested item is installed or placed in the center position of a semi-circular curved tube with the bottom of the splashed sample at a horizontal position with the swing axis. During the test, the sample rotates around its center line.
