1. Hazards of pipeline vibration Low-intensity mechanical vibration is inevitable in the rotating equipment and flowing medium of the unit. The mechanical vibration of the rotating equipment is transmitted to the system pipeline through the system connection components and the medium, thus posing a great threat to the safe operation of the unit. The hazards of pipeline vibration mainly include the following points:
1. Hazards to workers:
It interferes with the vision of workers and reduces construction efficiency; workers feel tired; it leads to quality accidents or even safety accidents; long-term work in a vibration environment of considerable intensity may cause great harm or impact to the health of construction workers. 2. Hazards to buildings:
Due to the different intensity and frequency of pipeline vibration, the building structure of some buildings will be damaged (common damage phenomena are cracking of foundations and walls, peeling of wall skin, sliding of stones, and in severe cases, deformation of the foundation of the building, etc.). 3. Hazards to precision instruments: Pipeline vibration can affect the normal operation of precision instruments and meters in the system, affect the accuracy and speed of reading the scale of instruments and meters, and even make it impossible to read the numbers. If the vibration is too large, it will directly affect the service life of instruments and meters, and even damage them; for some sensitive electrical appliances, such as sensitive relays, vibration may even cause them to malfunction, which may cause some major accidents. 4. Hazards to the main equipment of the system: Long-term pipeline vibration will cause uneven output of the main equipment of the system, affecting the mechanical properties and normal operation of the main equipment. 2. Causes and elimination measures of pipeline vibration The fundamental cause of pipeline vibration in the unit system lies in the design, installation, operation and operation of the unit. The system pipeline vibration directly reflects the mechanical properties and operation of the rotating equipment. When the system equipment and pipelines vibrate, the possible causes of vibration should be analyzed one by one according to the specific situation. After finding the crux of the problem, feasible and effective treatment measures should be formulated after careful discussion and analysis to eliminate it and reduce the vibration hazards to a minimum.
