| 摘 要： | 我厂1台PG5361型燃气轮机大修前一段时间以及大修后开机时振动都较大,影响了机组的安全运行.根据振动现象,判断转子上存在一定程度的不平衡.受机组结构限制,现场动平衡只能在两端联轴器上进行.多次动平衡过程中出现了多点振动矛盾以及临界转速和5 100r/min定速下的振动矛盾等现象.对振动现象和动平衡过程作了详细介绍,对...

| Abstract: | Large vibration occurred in a PG5361 gas turbine of our plant before and after the overhaul of the unit.It influences the safe operation of the unit.Based on the test results,we decided that there is unbalance fault in the rotor.Limited by the unit structure,we can only balance the rotor on the two end couplings.Conflicts between the multiple points and multiple conditions occurred during balance process.The paper presents the vibration phenomenon and balance process in detail.The way to improve balance eff... |
