摘　　要：丙烯压缩机是乙烯装置中的关键设备,本文基于数值模拟方法,以某企业的乙烯装置中丙烯压缩机为研究对象,详细计算了平衡气对机组一段参数的影响和平衡盘密封形式对机组性能的影响。结果表明,平衡气导致一段入口温度升高,体积流量增大,导致一段性能出现偏差,采用小间隙可磨密封替代原有的金属梳齿密封可以有效减弱这一影响。The propylene compressor is the key equipment in the ethylene plant. In this paper, numerical study has been carried out for a propylene compressor of the ethylene plant of an enterprise. The influence of the balance gas on the first-stage of the unit and the influence of the sealing forms of the balance disc on the performance of the unit are calculated in detail. The results show that the balance gas leads to an increase in the inlet temperature and volume flow rate of the first stage, which leads to a performance deviation of the first stage. The use of a small gap abradable seal to replace the original metal seal can effectively reduce this influence.
