首先,德国海隆(HERION)电磁阀的防爆标示EEx mdⅡCT6只是海隆公司产品隔爆的标识而已,其中md在Herion是封装后再隔爆的意思,即整个线圈先用环氧树脂进行浇封裹装,再在外面加罩一层金属防爆盒,4600系列为铝合金的4800为不锈钢的,整个线圈是用金属外壳封装一体式的。 其次,美国ASCO电磁阀的VCEF系列防爆标示EEx mdⅡCT6,其中md在ASCO是浇封防爆的意思,即整个线圈先用环氧树脂进行浇封裹装,再外接一个防爆接线盒,而这个线圈的核心部分其防护等级实际上为EEx mⅡT4,起隔爆作用的只是那个接线盒,但并没有罩住线圈,也就是说并不是真正的防爆电磁阀。 再次,其次美国ASCO电磁阀的VCEF系列是在上海生产的,并非美国或是欧洲进口的,而德国海隆(HERION)电磁阀全部是德国原装进口的,其质量和安全性能是远高于VCEF系列。也就是说德国海隆电磁阀的EEx mdⅡCT6防爆等级是等同于美国ASCO电磁阀的EEx dⅡCT6防爆等级。美国ASCO电磁阀的NF和WSNF系列,是在线圈外面直接罩防爆接线盒的,这有别于HERION的先浇封后罩防爆接线盒的,即德国海隆(HERION)全金属封装后的EEx mdⅡCT6 防爆等级高于美国ASCO末封装的全金属外壳EEx dⅡCT6 的。 最后,要辨别电磁阀是不是真真防爆的不仅仅要看防爆等级,还要看起线圈和接线盒的位置,如果是接线盒罩住线圈的就是真真防爆的,如果线圈外接了接线盒就是浇封的,只是外接了一个防爆接线盒而已。
