What are the application areas of sand and dust test chambers?

The core function of the sand and dust test chamber is to simulate natural sand and dust environments, test the sealing and dustproof performance and sand and dust erosion resistance of product shells. Its application areas cover all industries that have strict requirements for outdoor reliability and sealing performance of products, and can be specifically divided into the following categories:

New energy vehicles and traditional automotive industry

This is one of the core application areas of sand and dust test chambers. Whether it is traditional fuel vehicles or new energy vehicles, a large number of components need to pass dust tests to ensure outdoor safety, such as:

The battery pack, motor, and electronic control system of new energy vehicles;

Car lights, wheel hub motors, sensors, connectors, air conditioning filters;

Relays, wiring harnesses, intake systems, etc. inside the engine compartment.

The relevant tests must comply with specialized protection standards for the automotive industry, such as ISO 20653 and GB/T 4208.

Consumer electronics industry

Test the dustproof level and stability of electronic products that need to be used in dusty environments such as outdoor, desert, and construction sites, including:

Outdoor portable devices: three proof mobile phones, outdoor intercoms, sports cameras, smart watches;

Smart homes and appliances: robotic vacuum cleaners, air purifiers, outdoor projectors;

Other devices: drones, portable chargers, and in car electronic devices.

Electrical and Industrial Equipment Industry

Industrial environments often have a lot of dust, and the sealing and dustproof ability of equipment directly affects its service life and operational safety. Typical test objects include:

High and low voltage electrical appliances: switchgear, circuit breakers, contactors, junction boxes;

Industrial control equipment: PLC controllers, sensors, frequency converters, motors;

Lighting equipment: mining lights, street lights, explosion-proof lights.

Rail Transit Industry

The operating environment of transportation vehicles such as trains and subways is complex, and dust from tunnels, deserts, and sandy areas can invade the interior of the equipment. Therefore, the following components must undergo dust testing:

Train window seals, air conditioning systems, door motors, and signal receivers;

Signal machines, switch control systems, and cable joints next to the track.

Aerospace and * * industry

The field requires equipment reliability, and sand and dust testing is one of the core environmental testing projects. The testing objects include:

The body shell, propeller motor, and flight control system of the drone;

**Equipment, radar equipment, communication radio, outdoor monitoring instruments.

Other special fields

Photovoltaic new energy: junction boxes and bracket connectors for photovoltaic inverters and photovoltaic modules;

Construction machinery: cab seals for excavators and loaders, hydraulic systems, instrument panels.
