Kuwala kosaphulika ndi chipangizo chamagetsi chokhala ndi chotchinga chosaphulika chopangidwa ndi aluminum alloy material.. Pamene mpweya wophulika umalowa m'bokosi ndikuyaka, the explosion-proof enclosure can withstand the internal explosion pressure of the gas mixture and prevent the internal explosion from spreading to the surrounding explosive mixture outside the casing.
The principle of gap explosion-proofing involves using metal gaps to halt the propagation of explosion flames, cooling the temperature of the explosion products to extinguish and reduce the heat.
