Zeal - 20L Spherical Explosion Tester
20L Spherical Explosion Tester is a professional testing instrument for determining the maximum explosion pressure, maximum explosion pressure rise rate, and explosion index of dust cloud explosion under specific testing conditions. It is mainly used for dust explosive evaluation of aluminum powder, zinc powder, plastic powder, intermediate of organic synthetic drugs, wheat powder sugar, sawdust, dyestuff, bakelite ash, milk powder, and other production and processing places.
Maximum Explosive Pressure, Maximum Explosive Pressure Rate of Rise, Explosive Index
Combustible Dust
Combustible Dust Explosion, Combustible Dust Classification, Dust Testing
- Tests the explosion parameters of dusts, gases and mixed solid/gas systems.
- Built-in international common test standards, either according to the standard parameters of the test, can also be customised.
- Chemical ignition and electrostatic ignition, suitable for different testing purposes.
- Explosion vessel with water-circulating jacket for constant temperature of the test environment
- Input the target concentration value, automatic cleaning, evacuation, and complete gas distribution as required.
- Dust dispersing device capable of completely and uniformly dispersing the dust into the explosion vessel.
- Experiments are carried out automatically without human intervention.
- Real-time display of time and pressure, more intuitive testing process.
- Experimental results include time-pressure curves, providing detailed information about the explosion.
- Remote control, to ensure the personal safety of experimental personnel.
- Adopt computer control, strong data analysis ability, accurate judgement of curve characteristics.
