摘要
在很长一段时间里,因为没有找到控制空压机振动值的有效办法,5#空压机的运行一直处于不稳定状态。在寻找空压机振动规律及控制办法的过程中,发现空压机系统的三轴对中状态对振动的影响很大。进一步详细分析外方所提供的5#、6#空压机对中标准的计算过程,发现二者的差别在于对墙板的温差取值不同。为此,在不同环境温度下分别对5#、6#压缩机支撑墙板、增速箱箱体、混凝土基础的温度分布进行长期跟踪测量。根据测量的数据,从理论计算上初步确定了5#空压机组对中原则。在以后的检修中按上述确定的原则进行对中,其振动值长期稳定,说明上述对中原则与实际的对中值是吻合的。
Due to lack of effective ways of controlling the vibration, No. 5 air compressor in the oxygen plant has been in a state of instability for a long time. In the process of seeking its vibration law and controlling methods, it was found that the alignment status of the three axes （axes of the compressor, gearbox and generator） greatly influences a compressor＇ s vibration. The calculation process of the alignment standards for No. 5 and No. 6 air compressors provided by the foreign supplier was analyzed in detail, and it was found that difference between the two compressors lies in they take different values of the supporting wall＇ s temperature differences. Because of this, the temperature distribution of the two compressors＇ supporting walls, gearboxes and concrete foundation has been followed and measured continuously Based on the long-term measurement data, a new alignment principle was established theoretically In recent overhauls, the principle established has been implemented and the result shows that the compressor＇ s vibration value is stable for a long time, which indicates that the new alignment principle tallies with the real situation.
