摘　　要：由于尿素水解器给料泵的国产轴承座同心度太差及轴承座与泵体配合处的止口位置配合基准受到破坏,导致尿素水解器给料泵振动大。采用更换轴承座、轴的结构及级间密封进行改造等措施,振动情况得到有效改善。As a poor concentricity of home-made bearing seat of urea hydrolyzer feed pump and the damaged coordination datum is causing a vibration of urea hydrolyzer feed pump,such measures as the replacement of bearing seat,transformation of shaft structure and interstage seal are employed and the vibration is effectively improved.

关 键 词：尿素水解器给料泵 轴承座 级间密封 轴 动平衡
