| High Light | 140L/m²/h Dripping Speed Anti-Drip Test Chamber ，0-500mm Dripping Height Waterproof Test Chamber ，SUS304 Stainless Steel Drip Test Equipment | ||
The DO-160G Civil Aviation Electronics Anti-Drip Test Equipment is designed for waterproofness testing of airborne equipment and avionics exposed to falling or dripping water during aircraft operation.
The system simulates a controlled dripping-water environment over the test sample and helps evaluate whether the enclosure and equipment can maintain the required performance after water exposure.
The test is designed to verify whether W-type avionics equipment can maintain proper performance when exposed to a dripping water environment. It evaluates the protective performance of the product enclosure against water dripping.
The equipment controls the water supply flow to achieve the required dripping rate of 140 L/m²/h. It generates a uniform water flow over the entire surface of the test sample enclosure to simulate the specified dripping environment.
The system controls the water supply flow to maintain a dripping rate of 140 L/m²/h and provides uniform water distribution across the entire surface of the sample enclosure.
AC 220 V ±5%, 50 Hz
The equipment should be installed and operated under the following conditions:
| Item | Requirement |
|---|---|
| Ambient Temperature | 15–35°C |
| Relative Humidity | 25–75% RH |
| Atmospheric Pressure | 86–106 kPa (860–1060 mbar) |
| Installation | Flat ground with suitable lighting |
| Electrical Safety | Waterproof leakage switch or socket |
| Water & Drainage | Good water inlet and drainage facilities |
Use clean water or impurity-free tap water. The equipment is equipped with a water cleaning and filtration device to help ensure suitable water quality for the dripping test.
| Control and operation | PLC and touch screen intelligent control system |
| Inner and outer box dimensions | Inner box WDH=1000×1000mm×1000mm, outer box WDH=1280×2050mm×2150mm |
| Dripping test area | WD=800×800mm, other sizes can be customized |
| Dripping height | The distance between the needle and the sample is 0-500mm, by adjusting the turntable height or raising the sample |
| Dripping speed (water flow) | 140L/m²/h, automatic adjustment, refer to standard figure A, the equipment uses an electronic flow meter to control the amount of water injected into the water tank, so that the water output of the needle meets the standard requirements |
| Schematic drawing |
|
| Rain drip tray pinhole diameter | 0.33mm±0.01mm |
| Drip hole spacing | 25mm×25mm, Matrix arrangement |
| Liquid temperature monitoring, ambient temperature monitoring, | The equipment is equipped with a thermostat, which can heat the sample. Ensure that the sample temperature is at least 10°C higher than the water temperature. The temperature parameters are limited according to JJF1101. Ensure the temperature uniformity in the experimental chamber. |
| Drip box location | Located on the top of the inner box, fixed position. |
| Test time | 0-99.9min, can be preset. |
| Box material | The inner box is made of SUS304 stainless steel. |
| Water circulation system | The water inlet has a cleaning filter device, and the test dripping water is automatically collected into the water tank through the chassis and can be recycled. |
| Safety protection | Phase sequence protection, leakage protection, water shortage protection, abnormal protection |
