UL 9540A Cell Level Test Explosion Chamber for Gas (Ambient Temperature)

Description:

Spherical pressure explosion test is a general test method for studying the combustion and explosion parameters of explosive materials such as dust and gas. By using a spherical container, it is possible to simulate a real explosion scene and measure key parameters such as the maximum pressure and pressure rise rate generated during the explosion. 

Detailed explanation:

Test principle:

The 20L spherical explosion test system is usually a container with a spherical structure, which contains the dust or gas to be tested.

Test purpose:

By igniting the dust cloud or gas, the pressure change generated during the explosion is measured to determine the maximum explosion pressure, maximum explosion pressure rise rate, explosion index and other parameters of the dust cloud or gas.

Test parameters:

Maximum explosion pressure (Pmax): The maximum pressure value generated during the explosion reflects the intensity of the explosion.

Maximum explosion pressure rise rate (dp/dt)max: The peak value of the pressure rise rate, indicating the severity of the explosion.

Explosion index (Kst): Used to assess the degree of danger of the explosion, which is related to the maximum pressure and the maximum pressure rise rate.

Other parameters: such as the lower limit of dust explosion, limiting oxygen concentration, etc.

Features:

• Spherical pressure test containers have extremely high pressure-bearing capacity.
• High-frequency data sampling system accurately measures parameters such as maximum explosion pressure.
• Magnetic stirring device fully stirs the mixed flammable gas.
• Constant temperature control device accurately controls the gas temperature before testing.
• Integrated design, using floor-standing movable cabinet for full installation.
• Computer automation control, the entire test is controlled by the test software.
