天然气液化工厂冷剂压缩机是液化工厂的大型关键设备,工艺要求需要调速,目前已投产的项目中有些采用涡轮机调速方式,但应用后发现调速效果差,效率低,噪声大。随着高压大容量变频调速技术的发展,高压变频器已得到了广泛的应用。冷剂压缩机要求调速范围宽,调速动态性能高,采用高压变频器调速系统,能很好地满足各方面的运行要求。
Natural gas liquefaction plant The refrigerant compressor is a large-scale key equipment in the liquefaction plant. The process requirements require speed regulation. Some of the projects that have been put into operation now adopt the turbine speed regulation method, but the application shows that the speed regulation effect is poor, the efficiency is low, and the noise is large. With the development of high-voltage high-capacity frequency control technology, high-voltage inverter has been widely used. Refrigerant compressors require a wide range of speed control, speed dynamic performance, the use of high-voltage inverter speed control system, can well meet all aspects of operational requirements.
