Explosion Proof Chamber

Explosion Proof Chamber is a kind of reliability testing equipment which adds explosion-proof hinges and other components on the basis of constant temperature and humidity test chamber. It realizes reliability verification of products under temperature changes. It mainly provides temperature change environment for scientific research and production units such as aviation, aerospace, automobile, materials, petroleum, chemical, electronics, and communications, so that users can conduct temperature stress screening tests on complete machines (or components), electrical appliances, instruments, materials, etc., so as to assess the adaptability of the test products or evaluate the behavior of the test products. It truly reflects the adaptability of electrical and electronic products to temperature environment changes during actual use and exposes product defects. It is an indispensable and important test method in the whole process of new product development, prototype testing, and product qualification testing.

reliability test of chamber

The Explosion Proof Chamber has added an explosion-proof safety door and fire extinguishing device: to prevent the new energy battery from accidentally exploding and generating shock waves during the test, the door will automatically pop open under the action of air pressure to avoid damage to the chamber. At the same time, it is equipped with an explosion-proof chain to lock the chamber to maintain structural stability. The window safety net prevents debris from directly impacting the window.

The top of the chamber is equipped with a fire extinguishing system, which is detected by high-precision smoke sensors and temperature sensors. When one sensor senses a fault, it will immediately alarm and the test chamber will stop working. When two sensors alarm at the same time, the fire extinguishing device will be activated.

Explosion Proof Chamber is composed of temperature system, humidity system, explosion-proof system, refrigeration system, heating element, cooling element, controller, observation window, universal wheel and other parts.

High-strength explosion-proof material: The test chamber is made of high-strength explosion-proof material, which can withstand the possible explosion pressure inside and effectively prevent the explosion fragments from damaging the external environment.
Explosion-proof electrical system: Equipped with advanced explosion-proof electrical system to ensure that even if an accident occurs during the test, the power supply can be quickly cut off to prevent the situation from escalating.
Emergency pressure relief device and gas detection alarm system: Provide all-round safety protection.
High-precision temperature and humidity sensors and advanced control systems: Through these devices, the test chamber can achieve accurate adjustment and constant maintenance of the temperature and humidity inside the chamber.
