摘　　要：国内某50万t/a催化汽油加氢脱硫装置循环氢压缩机采用往复式压缩机,装置运行期间压缩机出入口管道存在低频次高振幅脉冲振动情况,最大振幅达到40 mm/s。通过分析原因,制定相应解决办法,将往复式压缩机出入口管道振动振幅降低至4 mm/s^6 mm/s,基本消除了管道振动带来的安全隐患,保障了装置安全运行。The reciprocating compressor is used in a domestic 500000 t/a catalytic gasoline hydrodesulfurization unit.During the operation of the unit,low frequency and high amplitude pulse vibration exists in the inlet and outlet pipes of the compressor,and the maximum amplitude reaches 40 mm/s.By analyzing the causes and formulating the corresponding solutions,the vibration amplitude of the inlet and outlet pipeline of reciprocating compressor was reduced to 4 mm/s^6 mm/s,which basically eliminated the potential safety hazard caused by pipeline vibration and ensured the safe operation of the device.
