The original poster can take a look at the following posts: Analysis of the reasons for the shutdown of steam compressors and preventive measures: http://bbs.hcbbs.com/thread-390233-1-1.html Analysis of the reasons for the shutdown of raw material gas compressors in synthesis units and solutions: http://bbs.hcbbs.com/thread-390230-1-1.html Analysis of the reasons for the shutdown of CO2 compressors and handling methods: http://bbs.hcbbs.com/thread-390228-1-1.html I hope this information will help resolve the poster’s issue!

Different types of compressors have different requirements regarding outlet pressure. Which category does LZ belong to?
There should be no outlet pressure alarm that causes the compressor to shut down immediately, but fluctuations in outlet pressure may lead to other issues such as excessive vibration or abnormal shaft displacement, which in turn can cause the compressor to shut down. So other data can be viewed.
Whether to initiate an emergency shutdown depends on whether an emergency shutdown interlock is installed; such interlocks are generally not provided in systems that are not sensitive to fluctuations in outlet pressure
Check whether there is a interlock for shutdown in your setup; if not, it certainly won’t shut down. As mentioned above, this could trigger other interlocks that cause shutdown
