随着化肥工业的发展,在合成氨生产中,高压循环机填料的漏气一直是人们所普遍关心的问题。因为它的气体大量泄漏,不但影响到工厂正常生产,而且还直接威胁到工人的生命安全。因此杜绝填料的泄漏气或减少泄漏,对提高产品产量、降低成本,增加收益有较大的意义。可是从压缩机设计和制造水平来讲,填料的泄漏又是充许的,其界限值有待进一步在实际生产中和压缩机的设计水平上进一步确定。 With the development of fertilizer industry, in the production of ammonia, the leakage of high-pressure recycle machine packing has always been a common concern. Because of its massive gas leakage, not only affects the normal production of the factory, but also a direct threat to the safety of workers. Therefore, to prevent leakage of packing gas or reduce leakage, to improve product yield, reduce costs and increase revenue have greater significance. However, from the compressor design and manufacturing level, the filler leakage is allowed, the threshold value to be further in the actual production and compressor design level to further determine.
