Description of Explosion-proof Structure


Various special circumstances are adequately considered during structural design, so that
no explosion will occur in the environment full of explosive mixture outside the equipment
if sparks are generated in the equipment; moreover, the explosion-proof performance of
the equipment is guaranteed from the following aspects: enclosure strength, gap between
components, and highest surface temperature limitation of enclosure.

The explosion-proof enclosure after finish machining must be able to withstand the
hydraulic test pressure specified in GB3836.2: 2.0MPa, not less than 10s, judged as
qualified in case of no water dripping and intact structure.

The highest surface temperature of enclosure shall not exceed +80º C during normal
operation.

The lead-in device for the camera is fastened with the hold-down nut.

The sight window of the camera is made of tempered glass, and thus can withstand the
impact and thermal shock tests.
