High compressor shaft vibration
Thread Content
Please tell me why the compressor 553ABCD rose at four points at the same time.
There are many types of compressors. What type are you referring to? 553ABCD What is this? When asking questions, be specific. Only if you understand it yourself and others can understand it can you participate in the discussion. Finally, take a guess to see if it is caused by load changes, for reference.
AC and BD are two sets of the same data respectively. Because the locations of the measuring points are different, the values are also different. From the chart, the trends of the four points are consistent, becoming larger or smaller at the same time. So you have to analyze it based on your actual operating conditions. Personally, I think it is caused by the load change of the compressor.
