往复压缩机管道振动原因及防振设计

Sources of Piping Vibration in the Operation of Reciprocating Compressors and the Preventive Measures in the Engineering Design

往复压缩机的管道振动是现场最常碰到的问题之一。从振动的基本概念、产生的原因、以及API618《石油、化工和气体工程用往复压缩机》对振动控制的要求进行了分析说明,最后从机械专业的角度提出了往复压缩机在工程设计中管道防振设计时应注意的问题和方法。根据本文推荐的设计方法进行设计的往复压缩机的管道在现场振动很小,能满足API618《石油、化工和气体工程用往复压缩机》的要求。

The piping vibration in the operation of reciprocating compressors was one of the most commonly problems in the worksite. The basic concepts and sources of vibration,and the requirements on vibration control in API618 《 Reciprocating Compressor for Petroleum,Chemical and Gas Industry Services》 were analyzed. Some issues needing to pay attention to avoid the piping vibration from the perspective of machinery were put forward. The reciprocating compressors based on the design method recommended in this paper,had small vibration in the worksite,which could meet the requirements of API618 《Reciprocating Compressor for Petroleum,Chemical and Gas Industry Services》.
