一种现场修正烧结机转子平衡状态的方法

A Method for Correcting the Rotor Balance on Site in a Sintered Exhauster

为避免烧结机转子在现场修复过程中平衡状态破坏导致机组振动异常,本文提出一种现场修正烧结机转子平衡状态的方法。该方法综合考虑转子在整体结构、阻尼、支撑刚度、角速度等不变的条件下,轴承箱的壳体振动速度与扰动力的角度不变的特性,运用刚性转子重量、加重半径、加重重量的关系,采用现场动平衡质量校正技术,保障机组可正常稳定运行。

To avoid a vibration fault caused by an unbalanced rotor in a sintered exhauster, this paper presents a method to correct the rotor balance. The method deals with the unbalance fault by calculating the relation equation of the rigid rotor weight, the weighting block radius and weighting block weight, which are under the conditions of structure, damp, support stiffness, and angular velocity of the rotor. The vibration velocity of the bearing box volute and the forcing angle is kept constant.
