摘要：针对BX32往复式压缩机投用以来一直存在振动过大、运行不稳定等问题，对其进行了改造。通过对BX32往复式压缩机结构进行理论和有限元的振动分析，得出了支承杆共振是引起缓冲罐焊缝断裂、机器振动的主要原因。对压缩机的支承进行了重新设计，通过实施得到了满意的工业应用效果。

Abstract: Aiming at its extra vibration problem and operation instability, the BX32 type reciprocating compressor was transformed. The structure of the reciprocating compressor was analyzed by the finite element analysis(FEA) and vibration theory, and the result shows that the resonance of support beams is the main factor of the welding seam breakage of the buffer vessel and vibration of the compressor. The reciprocating compressors support part was redesign, which gets sound effets on the industrial applications.
Key words: reciprocating compressor; pipe vibration; vibration reduction; finite element analysis(FEA)
