氢气压缩机广泛应用在石油化学工业部门。近年来,在石油炼制工业中,由于广泛采用先进的加氢工艺,因此,迫切要求机械工业大量提供先进的成套加氢设备,氢气压缩机及其配套电气设备是不可缺少的项目之一。 氢气活动性很强,是易爆气体,若与空气混合达到一定浓度,一旦遇有火源或危险温度就会引起爆炸,造成生产现场的严重破坏事故。与氢气压缩机配套的电气设备在工作中是可以产生火花、电弧、危险温度的辅助设备,因此,防爆是确保氢气压缩机工作现场安全的 Hydrogen compressors are widely used in the petrochemical industry. In recent years, due to the extensive use of advanced hydrogenation processes in the petroleum refining industry, it is urgently required that the machinery industry provide large quantities of advanced complete hydrogenation equipment, hydrogen compressors and their associated electrical equipment, which are indispensable items. Hydrogen activity is very strong, is explosive gas, if mixed with air to a certain concentration, in the event of a fire or dangerous temperature will cause an explosion, resulting in serious damage to the production site accident. Hydrogen compressor supporting electrical equipment in the work can produce sparks, arcs, dangerous temperature auxiliary equipment, therefore, explosion-proof is to ensure the safety of hydrogen compressor work site
