防火的三個基本要素是什麼

隔爆接頭寬度:

也稱為爆炸接頭長度, 它表示從隔爆外殼內部到外部穿過爆炸縫的最小路徑長度. 這個尺寸至關重要，因為它代表爆炸能量耗散最大化的最短路線.

隔爆接頭間隙:

This term refers to the gap between flanges at the point where the body of the enclosure meets its cover. Generally maintained at less than 0.2mm, this gap is pivotal for achieving the best 隔爆型 effect, aiding in the reduction of both explosion temperature and energy.

Flameproof Joint Surface Roughness:

During the fabrication of the flameproof enclosure’s joint surfaces, attention must be paid to the surface roughness. For flameproof electrical equipment, the roughness of these joint surfaces must not exceed 6.3mm.
