Model significance

Explosion-proof points

When the explosive gas mixture inside the flameproof submersible pump motor explodes, the flameproof enclosure shall not be damaged, and the internal flame will not ignite the explosive environment formed by one or more gases or vapors outside through the flameproof enclosure joint surface. The parts that make up the flameproof enclosure are hydrostatic tested in accordance with GB3836.2-2000 to ensure that they can withstand the maximum internal explosion pressure.

The flameproof mark of this flameproof submersible sewage pump is ExdIIBT4, which is suitable for the explosive mixture of combustible gas or steam and air formed by the temperature group T1-T4 in the factory class ⅡB. The maximum surface temperature of the unit must conform to the following table:
