应用卸压装置降低外壳内爆炸压力,是减少制造矿用电气设备隔爆外壳金属用量的一个途经。通常在发生爆炸时,都是通过零件连接处的隔爆间隙使壳内卸压的。为了加强这一效果,可以做成外壳内部与矿井大气连通的专门隔爆槽。为采用这类卸压装置,不仅要知道卸压效果,而且要知道防尘性能。对此,马克耶夫科学
The application of pressure relief devices to reduce the explosion pressure in the enclosure is a way to reduce the amount of metal used in the manufacture of flameproof enclosures for mining electrical equipment. Usually in the event of an explosion, are through the parts of the explosion-proof gap at the junction of the shell to the pressure relief. In order to enhance this effect, it can be made as a special explosion-proof tank which connects the interior of the shell with the atmosphere of the mine. To use this type of pressure relief device, not only to know the effect of pressure relief, but also to know the dustproof performance. In this regard, Markyev science
