一、问 题的提 出 化肥厂和化工厂（或其他使用单位）除了需要定型的氢氮压缩机和循环机外,往往还需要各种能满足其他工艺要求的特殊压缩机,即使是氢氮压缩机,如果流程不同,使用时往往也会带来一些问题。对于这些非定型的压缩机,由于数量少、品种多,制造厂一般都不愿意制造。在制造厂任务不足时,或许会接受一些,但一是成本高,价格昂贵; 二是制造周期长,交货往往会脱期,以致影响使用单位的施工进度。因此,一旦需要这类压缩机时,使用单位就会感到困难。另一方面,许多化肥厂为了扭亏为盈,需要节能改造,总的趋势是使用容 First, the issue put forward Fertilizer and chemical plants (or other users) in addition to the need to stereotypes hydrogen and nitrogen compressors and recycle machines, often also need a variety of special compressors to meet the requirements of other processes, even if the hydrogen nitrogen compressor , If the process is different, often bring some problems when using. For these non-stereotypes compressor, due to the small number of varieties, manufacturers are generally not willing to manufacture. In the factory when the task is not enough, may accept some, but one high cost, expensive; the other is the long manufacturing cycle, delivery will often be out of date, so affect the use of the construction progress of the unit. Therefore, once you need such a compressor, you will find it difficult to use the unit. On the other hand, many fertilizer plants need energy-saving retrofits in order to turn a profit, and the general trend is to use
