Users equipped with piston compressors often encounter the phenomenon of pipeline displacement, support deformation and severe noise caused by pipeline vibration, which has a negative impact on safety production. Therefore, it has great significance to thoroughly solve the vibration problem of the pipeline of the piston compressor to ensure the safe production of the air separation plant.
1.The reason analysis of pipeline vibration of piston compressor:
There are many reasons for pipeline vibration of piston compressor. According to many years of production practice and professional research, the main reason for the vibration of piston compressor is air flow pulsation. In addition, because the system composed of pipeline and internal gas has a certain natural frequency, if the excitation frequency of compressor is equal to or close to the natural frequency of the system, resonance will also occur, making the pipeline appear large amplitude.
2.Vibration reduction measures
1）A buffer tank can bearranged near the exhaust port of the compressor cylinder, which can effectively isolate the compressor cylinder from the pipeline and reduce the pulsating air flow through the buffer tank.
2）Adding a proper size orifice plate at the buffer inlet can reduce the pressure pulsation in the pipeline and enhance the buffer effect of the buffer.
3）Adding a resonator between the compressor cylinder and the buffer can essentially reduce the gaspulsation of the pipeline.
Users of DEAR air separation can select the above methods according to their own conditions, and reasonably formulate control measures to eliminate the potential safety hazards caused by compressor pipeline vibration.
