What are the causes of vibration in ammonia synthesis compressors and how to address them?

To eliminate the vibration of compressors, actions are generally taken from the following aspects: 1. The moving parts must be statically and dynamically balanced; otherwise, inherent vibration factors will arise. 2. The concentricity between the compressor and the motor or diesel engine must be adjusted correctly. 3. The foundation of the compressor must be constructed in strict accordance with the design drawings. There shall be no rigid connection between the foundation and any structure of the building. 4. Vibrations caused by airflow pulsations require that auxiliary equipment and pipes be equipped with secure supports and clamps; cantilever supports should use reinforced brackets, and they must be tightened with shims. 5. The tightening torque of the machine’s foot screws must be consistent ； 6. The frame (base) must have sufficient stiffness

First, check if there are any issues with the machine, and then see whether it follows the principle of increasing rotation speed first when boosting pressure or reducing pressure first when decreasing it. In fact, centrifugal compressors are very useful.
