我院炼油实验厂催化裂化装置所用气体压缩机是西德DEMAG公司制造的KA_3-V型二段五级离心式压缩机。流量70Nm~3/分,进口压力1.6kg/cm~2(绝),出口压力16kg/cm~2(绝)。与压缩机配套的是西门子公司制造的低压冷凝式变速汽轮机。功率1000KW,正常转速14570转/分。在该压缩机的安装及调试过程中,分析了由气动仪表组成的防喘振调节系统中各仪表的原理结构及其在系统中的作用,掌握了各仪表的参数整定、调校及投用方法,进行了喘振试验,并绘出压缩机的实际喘振曲线及防喘振控制操作曲线,对原设计的错误及不合理之处也进行了适当的修改。下面就该压缩机的防喘振控制系统的组
Gasoline compressor used in FCCU catalytic cracking plant in our hospital is KA_3-V two-stage five-stage centrifugal compressor manufactured by West Germany DEMAG Company. Flow 70Nm ~ 3 / min, inlet pressure 1.6kg / cm ~ 2 (absolutely), the outlet pressure 16kg / cm ~ 2 (absolutely). Comparable with the compressor is made by Siemens low-pressure condensing variable speed steam turbine. Power 1000KW, normal speed 14570 rev / min. During the installation and commissioning of the compressor, the principle and structure of each instrument in the anti-surge regulation system composed of pneumatic instruments and their functions in the system were analyzed. The parameters of each instrument were adjusted, adjusted and put into use Method, the surge test was carried out, and the actual surge curve of the compressor and the anti-surge control operation curve were plotted. The errors and unreasonable aspects of the original design were also appropriately modified. Below the compressor anti-surge control system group
