Vibration problems in reciprocating compressors
Thread Content
I would appreciate your help: The circulator used in the methanol synthesis plant is a reciprocating compressor, and currently there are vibration problems in the pipelines and the buffer tanks of the unit. Our attempts to address these issues have not yielded significant results. Please help analyze the causes and suggest ways to solve this problem! Thank you.
There are too many factors that can cause vibration in reciprocating compressors; for now, it is recommended to reinforce the compressor. At the same time, it is advisable to consult the compressor manufacturer to analyze the causes of vibration and eliminate them.
The vibration of the compressor is analyzed from two aspects: first, it is checked whether the volume of each buffer is sufficient; second, the stress on the pipes is analyzed. Reinforcement, the addition of orifice plates, and dampers can all be used, but it is advisable to consult a professional for this task.
The volume of the buffer tank may be insufficient, and the strength of the pipeline reinforcement may not be adequate. Please have the design institute conduct an assessment
Check the following: 1. Whether the gasket in the middle of the pipe clamp has fallen off or become loose； 2. Whether the buffer tank gasket has fallen off or become loose ； Treat the symptoms.
We have encountered the same problem as well. The measure we take is to fix in place by manufacturing appropriate pipe supports (wooden pipe clamps). Additionally, it is necessary to analyze the differences between the current operating conditions and the designed process parameters; if the designed specifications are not met, the operating conditions that result in the least vibration should be determined by adjusting the gas composition and circulation rate.
Our variable capacity control system enhances compressor stability and reduces vibration
We switched to variable-speed control, and the vibration is much less now
