Solving stainless steel seamless elbow abnormal vibration requires a comprehensive three-dimensional approach from causal analysis, targeted treatment and systemic prevention.
The root cause of vibration tends to present multi-factor coupling characteristics, mechanical level is common in the installation pair deviation of more than 0.1mm caused by the periodic bending torque, a petrochemical enterprise case shows that the coupling coaxiality error of 0.15mm when the vibration acceleration can reach 4.5m / s², the deviation must be controlled within 0.05mm by the laser pair; the fluid dynamic factor is expressed as the media flow rate exceeds the critical value (such as the DN50 bend is above 2.5m / s). A chemical plant reduces the vibration range by 60% by reducing the flow rate to 1.8m/s. Resonance problems need to identify the inherent frequency of the system through modal analysis, and a nuclear power plant pipeline system uses an additional mass block to extend the avoidance bandwidth to ±3Hz, effectively avoiding the main pump excitation frequency.
Solving abnormal vibrations requires a balance between immediate effects and long-term stability.
For vibration that has occurred, the hydraulic buffer can absorb up to 90% of the impact energy. After an automotive manufacturer installs the exhaust system at the elbow, the vibration intensity is reduced from 7.1mm / s to 2.3mm / s. In terms of structural optimization, changing the 90 ° standard elbow to two 45 ° elbow combinations can reduce the flow resistance factor by 40%, and the water hammer phenomenon after the transformation of a heating pipe network is reduced by 75%.
