[Q&A Question No. 048] February 17, 2017: What are the consequences of improper adjustment of the compression ratios in various stages of a piston compressor? The reference answers can be seen after* replying; points will be awarded for identifying the key points. (Unless otherwise specified, all questions and answers are based on hydrogenation units.) ) The compression ratio is an important parameter in the design and operation of compressors. For the same cylinder and the same medium, the higher the compression ratio, the more severe the operating conditions become, and the greater the stress on various components. Furthermore, due to the presence of clearance volume, the higher the compression ratio, the lower the efficiency of the cylinder. Therefore, the compression ratios between different stages must be adjusted properly; improper adjustment can lead to excessively high temperatures at the cylinder outlet, disrupt the balance of forces in the compressor as intended, affect the operation of the unit, and cause other abnormal phenomena.

Uneven temperature, excessive compressor vibration

The air valve is overheating, the cylinder load is too high, and the exhaust temperature is too high
