多级给水泵初装减少晃动值算法探讨

预装是多级给水泵大修的重要内容,而减少转子的晃动又是预装所要解决得核心问题。本文从给水泵转子晃动值偏大的危害谈起,介绍了实际检修中减小晃动值的方法和这些方法存在的问题,又根据晃动与弯曲、弯曲与转子各部件端面平行度偏差的关系,推导出两个理论公式和一些经验数据。最后介绍了公式在实际检修中的应用和不同情况下公式的修正。

The First Making up is an important part of the heavy repair ot stage teed water pump while decreasing wobble value of rotor is the aim of it. The composition introduce the damage to rotor when the wobble value run over standard and educate tow formulas to prove the relation between the flexion of rotor and the parallel misalignment in the blocks of rotor. In the end ,instructed the application of the formulas in the restoration of stage feed water pump and the modified formulas in different condition.
