结合双螺杆变频调速压缩机在BEPCⅡ低温系统上的应用,研究压缩机吸气压力和排气压力控制方法。根据制冷机控制系统的PLC程序,得出压缩机吸气压力和排气压力的控制方法,并通过BEPCⅡ低温系统的实际运行情况对研究结论进行验证。
Combined with the application of double-screw VVVF compressor in BEPCⅡ cryogenic system, the control methods of compressor suction pressure and discharge pressure were studied. According to the PLC program of the refrigerator control system, the control method of the compressor suction pressure and the discharge pressure is obtained. The research conclusion is verified by the actual operation of the BEPCⅡ cryogenic system.
