摘　　要：压缩机出厂试验时难以用天然气进行试验,通常采用空气作为试验介质。但是,空气成分与天然气有很大差别,对压缩机进行试验时,其产生的风险与天然气不同。针对此问题,文章对压缩机试验介质改变后试验过程的风险源进行了识别,提出了利用FMEA-LEC方法分析试验过程存在的风险水平。研究表明采用空气试验时,气缸温度容易过高,易产生积炭问题,引发严重后果;并且空气中氧气成分是造成管路腐蚀的重要因素。最后,提出了13项控制措施,保障压缩机试验过程的安全。It is difficult for manufacturer to test compressor for sale with nature gas and instead,the cheap air is usually employed to test compressor.However,the compositions of air are very different from those of nature gas and therefore,risks produced by using air are also different from those by using nature when compressor is tested.In order to solve the problem,risk sources are identified during the test process as test medium of compressor has changed and FMEA-LEC was applied to analyze the risk level of test process.Research shows that the temperature of cylinder is vulnerable to become too high when using air,so that charcoal accumulation produced will result in serious consequences and meanwhile,as you know,oxygen in the air is the main composition bringing about corrosion of pipe.Finally,13 control measurements are put forward in this paper to ensure the safety of the test process.
