可逆锤击式破碎机异常振动分析及处理

Vibration Analysis and Diagnosis Disposal of Reversible Hammer Crusher

对某可逆锤击式破碎机异常振动进行了详细分析,指出转子质量不平衡、支撑系统刚度不足和锤臂卡涩是导致机组异常振动的主要原因。现场通过动平衡和更换新锤臂后,成功处理了该机组振动故障。

The abnormal vibration analysis and fault diagnosis of a reversible hammer crusher is presented.It was found that rotor mass imbalance,insufficient stiffness and hammer arm jammed are the major cause of the equipment abnormal vibra⁃tion.By dynamic balance and replacing hammer arm in field,the equipment vibration faults were solved successfully.
