Automotive parts sand and dust test chamber design overview
1. Main body of the test chamber
- Material selection: Stainless steel is used to ensure corrosion resistance and easy cleaning.
- Structure: airtight rectangular box with dimensions assumed to be 1.5 meters long, 1.2 meters wide, 1.8 meters high, and a volume of 3.24 cubic meters.
2. Sand and dust supply system
- Sand dust storage: Equipped with sand dust storage box with dustproof cover to prevent sand dust leakage.
- Injecting device: Using air jet device, sand dust is evenly sprayed into the test chamber through pipeline.
- Recycling device: The air extraction system will pump the sand dust back to the storage box to realize the recycling of sand dust.
- Filtration system: Installation of high efficiency air filter to prevent the sand dust from leaking to the outside, regular cleaning or replacement of the filter.
3. Air control system
- Temperature regulation: electric heater and compressor refrigeration system are installed at the bottom and top to control the temperature inside the test chamber.
- Humidity control: humidifier and dehumidifier are equipped to regulate the humidity inside the test chamber.
- Air flow regulation: Use fan and air duct to control the air flow speed and direction to ensure uniform distribution of sand and dust.
4. Sample Placement System
- Sample holder: Adjustable height and angle of stainless steel sample holder, adapting to different sizes and shapes of parts.
- Fixing method: Use clamps or bolts to fix the samples to prevent them from moving under the sanding dust blowing.
5. Observation system
- Observation Window: Dust-proof and impact-resistant observation window is installed to ensure the visibility of the test process.
- Lighting device: Equipped with LED lights to provide sufficient illumination for observing the condition of the parts.
6. Control system
- Hardware: PLC (Programmable Logic Controller) and touch screen operation interface are adopted.
- Function: Setting and monitoring parameters such as sand and dust concentration, temperature, humidity, airflow speed, etc., real-time display and recording of test data.
7. Safety Protection System
- Emergency stop button: installed on the outside of the test chamber, in case of emergency, the test can be stopped immediately.
- Pressure relief valve: set up a safety relief valve to prevent excessive pressure inside the test chamber.
8. Cleaning and maintenance system
- Dust Discharge: Equipped with an air extraction system to discharge the excess sand and dust outside the chamber to the external storage box.
- Chamber cleaning: designed with automatic cleaning function, using compressed air to blow the interior of the chamber, and regular manual cleaning of sand and dust deposits.
