Model and meaning
Explosion-proof main point
When the explosive gas mixture in the explosive-proof submersible sewage pump motor explodes, explosive-proof shell shall not be damaged and the internal flame will not cause further explosion. The parts of explosive shell are tested by water pressure tests according to GB3836.2- -2000 standard to ensure maximum internal pressure explosion.
The explosive-proof submersible sewage pump is marked as ExdlIBT4/ExdIICT4, which is suitable for factory IIB/IIC class, temperature group is T1-T4 of combustible gas and explosive mixture of steam and air. The maximum surface temperature must be in accordance with following list:
