Sand and dust test chamber: Kebao works hand in hand with you to build a reliable defense line for products in harsh environments

The following three typical cases witness the practical application of the Kebao dust test chamber in core industries such as automotive, electronics, and photovoltaics. With precise simulation, stable performance, and customized solutions, it helps enterprises overcome dust testing challenges.

1、 IP6X dustproof test case for automotive parts enterprises

——Requirement: To provide sand and dust environment testing for the lights, engine intake filters, and electrical dust covers of the new SUV. It is necessary to simulate desert strong wind and sand conditions, verify that the product meets the IP6X protection level, and ensure the durability of the vehicle in desert, construction sites, and other scenarios.

——Equipment: Kebao KB-SC-512 sand and dust test chamber, with a sand and dust concentration of 2-4kg/m ³, supporting 75 μ m standard sand screening, adjustable sand blowing and vibration time of 1S-99H, equipped with AI intelligent control system and large-area observation window+wiper device.

——Effect: Through 12 hours of continuous testing (wind speed of 40m/s, sand and dust concentration of 1000mg/m ³), the sealing defects of the filter element and the dust leakage of the car lamp joint were accurately exposed. Based on this, the company optimized the sealing process and the product passed third-party testing in one go. After being launched, the user complaint rate decreased by 68%.

2、 Outdoor electronic equipment manufacturers' non-standard customized sand and dust test cases

Requirement: For large outdoor surveillance cameras and portable power supplies, a customized large volume test chamber is required to simulate a high-temperature dry (50 ℃/25% RH)+sand and dust composite environment. The testing equipment should run continuously for 8 hours to ensure stability, and support remote data monitoring and multi particle size sand and dust switching.

Solution: Kebao customizes a 2100 × 2200 × 1400mm non-standard test chamber, using a stainless steel inner liner and a cold-rolled steel plate spray coating shell, equipped with a closed-loop flow field circulation system, adjustable sand and dust particle size of 0.1-100 μ m, integrated temperature and humidity linkage control and automatic data recording function, meeting the requirements of IP5X-IP6X multi-level testing.

Effect: After the experiment, it was found that the dustproof design of the camera circuit board was short, and the sealing of the power interface met the standard, providing accurate data support for product iteration. The equipment ran continuously for 3000 hours and obtained the manufacturer's annual high-quality supplier certification.

3、 Case study of desert environment adaptability testing for photovoltaic inverter enterprises

(1) Requirement: Simulate dust accumulation scenarios in desert power stations, test the heat dissipation efficiency degradation of inverters in high concentration sand and dust environments, and simulate long-term stable sand and dust deposition and wind disturbance to ensure the long-term reliability of equipment operation in desert areas.

(2) Equipment: Kebao large sand and dust test chamber, temperature range RT-45 ℃, equipped with automatic shock absorber and high-power circulating fan, adjustable sand and dust concentration 50-1200mg/m ³, supporting 72 hour uninterrupted testing.

(3) Effect: By simulating a 3-month equivalent sand and dust environment test, the attenuation curve of the inverter's heat dissipation efficiency was accurately calculated. Based on this, the enterprise optimized the dust prevention design of the heat dissipation channel. The product was operated on site at the Northwest Desert Power Station for 1 year, and the failure rate was reduced by 75% compared to the previous generation.
