Sand & Dust Test Chamber

The dust test chamber is a professional environmental simulation testing equipment, mainly used to test the adaptability of products in dusty environments.

From the appearance, it has a sturdy box, generally made of high-quality steel, and the surface is specially treated to prevent rust and corrosion. The internal structure is precise, and a fan system is equipped to generate airflows of different intensities to drive the dust to circulate in the box to simulate a real sandy environment.

During operation, the control system can accurately set parameters such as temperature, humidity, wind speed, and dust concentration. For example, it can simulate the harsh environment of high temperature, dryness, and dust in desert areas.

The dust test chamber has a wide range of applications. In automobile manufacturing, it can detect the dustproof performance of components such as the automobile engine intake system and air conditioning system; in the electronics industry, it can test the sealing of the electronic product housing and the stability of the internal components in a dusty environment. With its reliable performance and precise simulation capabilities, the dust test chamber provides strong support for product quality and reliability evaluation, ensuring that the product can operate normally in an actual dusty environment.

Electronics

Air purifier filter dust interception ability and dust holding capacity test.

Through the dust test, we can determine the proportion of dust particles of different sizes that the filter can effectively intercept, and understand its dust filtration efficiency. If the filtration efficiency drops too quickly, it means that the performance of the filter is unstable in a dusty environment. Based on the results of the dust test, we can optimize the design of the air purifier filter. For example, we can improve the material of the filter to improve its dust interception ability and durability; adjust the structure of the filter to increase the dust holding capacity or reduce the air flow resistance.

Materials

Agricultural functional film for dust test

Light-converting PO film has the property of converting light of a specific wavelength into light that is beneficial to the growth of crops, and has high light transmittance. However, dust may scratch the surface of the film, or dust particles may adhere to the film, changing its optical properties such as transmittance, haze, and light conversion efficiency. The test can quantify these changes and clarify the extent of the impact of dust on the optical properties of light-converting PO film, such as insufficient wear resistance, poor stability of optical properties, and great influence of dust on light conversion performance. It can optimize material formulations, improve production processes, and develop light-converting PO film products that are more suitable for dusty environments, enhance the market competitiveness of products, and promote technological progress in the industry.

New Energy Batteries

New energy vehicle battery cooling system undergoes dust test.

Dust may block the ventilation holes and heat sink gaps of the cooling system, hindering air circulation and reducing heat dissipation capacity. Through the test, we can quantify the degree of reduction in heat dissipation efficiency caused by dust accumulation and test whether the protective structure design of the cooling system is reasonable, such as whether the sealing strips, dust screens and other components can effectively prevent dust from entering the key heat dissipation area; observe the friction and collision between dust particles and cooling fan blades, the inner wall of the cooling duct and other components, and evaluate whether they will cause wear and deformation of components, affecting their mechanical properties and service life;

Rubber Plastics

Optical telescope Optical performance stability test.

The core function of a telescope is to provide a clear and accurate field of view. In a dusty environment, dust particles may scratch the surface of the lens or accumulate on the surface of the lens, affecting the transmission and refraction of light, and thus changing the optical properties of the telescope, such as imaging quality, clarity, and color reproduction. Through dust tests, the impact of dust on the optical performance of the telescope is quantitatively analyzed to determine whether it can continue to provide stable, high-quality observation results in a dusty environment. Telescope manufacturers can improve product design and production processes in a targeted manner based on the results of dust tests.

Metal mold

Sealing and protection performance test of metal molds

For die-casting molds that need to prevent metal liquid leakage and avoid the entry of external impurities, the sand and dust test can effectively test the effectiveness of its sealing structure. If sand and dust are found to enter the mold after the test, it means that there is a problem with the sealing performance of the mold. Possible reasons include aging of the sealing strip, unreasonable design of the sealing structure, insufficient mold processing accuracy resulting in excessive matching clearance, etc. For sealing problems, it is necessary to check the sealing parts in detail, analyze the leakage path, replace the sealing strip or optimize the sealing structure design, and improve the processing accuracy of the mold if necessary.

Aerospace

General aviation aircraft wings undergo dust testing

Dust may destroy the airflow stability on the wing surface and change the wing shape, thereby affecting the wing upgrade coefficient; increase friction resistance and increase pressure difference resistance, thereby increasing wing resistance; interfere with airflow to cause turbulence, affect flight attitude perception, and change the aerodynamic center position, thereby affecting aircraft stability and maneuverability; dust tests help evaluate the performance of wings in dust environments to ensure flight safety and operational effectiveness.

What are the safety protection functions of the sand & dust test chamber

Overload fuse protection: During the operation of the dust test chamber, when dust blocks the ventilation holes and causes the fan load to increase, or when a heating element failure causes current abnormality, the overload fuse protection will take effect, quickly cutting off the circuit and protecting the equipment.

Grounding protection: In the daily use of the sand and dust test chamber, the dust environment may cause certain erosion and damage to the electrical insulation, resulting in a decrease in insulation performance. At this time, grounding protection can effectively prevent the danger caused by the casing being electrified and ensure the safety of personnel and equipment.
