高速离心式压缩机在实际运行中,普遍存在振动问题,而联轴器的对中是否正常是其中的一个重要因素。若联轴器找正不良,就会使机组不能正常运行,齿轮联轴器的啮合就会遭到破坏,还会引起轴承发热,机器振动,既影响机器的使用寿命,又会因振动过大而造成机件损坏,因此,正确的找正是很重要的.一、概况离心式压缩机组的找正,都是根据制造厂家提供的冷态找正曲线进行的,这是根据经验并结合机组热膨胀情况而确定的。尚没有办法作出机组运行时的热态找正曲线,所以也就无法验证该冷态找正曲线是否能保证热态下仍能良好的对中。为此,美国克拉克 High-speed centrifugal compressor in the actual operation, the prevalence of vibration problems, and the coupling of the normal is one of the important factors. If the coupling is bad, it will make the unit can not be normal operation, the gear coupling meshing will be destroyed, but also cause bearing fever, the machine vibration, both affect the life of the machine, but also because of excessive vibration And cause damage to mechanical parts, therefore, the correct find is very important I. Overview Centrifugal compressor unit to find out, are based on manufacturers to find the cold curve to find a positive curve, which is based on experience combined with the unit Thermal expansion of the situation and determined. There is no way to make a positive hot-line finding curve when the unit is running, so it can not be verified whether the positive cold-line finding curve can still guarantee good alignment under hot conditions. To this end, the United States Clarke
