往复压缩机管路气流脉动分析与消减优化
Investigation and optimization of airflow pulsation reduction in the pipeline of a reciprocating compressor
摘要
Abstract
The safety of the pipeline is decreased by the periodic suction and discharge features of the reciprocating compressor,which are easily responsible for pipeline pulsation amplitudes that are too high.As a result,this research studied the secondary compression discharge line of a skid-mounted reciprocating compressor set with substantial pressure variations,employing numerical simulation methods to investigate pipeline airflow pulsation characteristics.According to research,the cylinder dynamic compression process,valve opening and shutting caused secondary compression exhaust pressure variations,and pipeline pressure pulsation amplitude exceeded the API 618 requirement.The secondary exhaust pipe's vibration test was conducted concurrently to ensure the validity of the modeling method and findings.In order to solve the issue of the secondary exhaust pipe's airflow pulsation amplitude exceeding the standard,the influence of the filter pipe on the pipe's airflow pulsation amplitude was examined,and an optimization study was conducted based on the orthogonal test to reduce the pipe's airflow pulsation amplitude.According to the results,the maximum pressure pulsation of the optimized pipeline was 37.02kPa,38.36% less than that prior to optimization,and the pipeline safety index was 80.4% higher,which lowered the risk of pipeline damage and increased the safety and stability of the reciprocating compressor set.关键词
