摘要
对我公司的1台6列M型活塞式压缩机组振动和噪声异常以及一级、二级连杆大头瓦快速失效的原因进行了分析。研究并实施了在轴系上加装配重体,以适度增大轴系的转动惯量来调整轴系扭转振动固有频率的改造措施,有效消减了轴系的扭转振动,大幅度减小了机组的振动和噪声,提高了连杆大头瓦的使用寿命。
The reasons causing abnormal vibration and noise, the accident ot connecting rod beanng scuff wear of first stage and second stage in short time in 6M type of reciprocating compressor are analyzed, which turns out the torsional vibration of the crank. To adjust the inherent frequency of the crank, the measures by assembling balance masses at the crank are implemented to enhance the rotational inertia of the crank. The amplitude of its torsional vibration is reduced effectly, the abnormal vibration and noise of the compressor are diminished greatly too, prolonged life of the connecting rod bearing.
