| 中文摘要:螺旋输送器是卧式螺旋离心机回转系统的重要组成部分，其作为唯一的不规则回转部件会随着离心机回转系统高速旋转，因此螺旋输送器的动平衡精度会对整机的使用寿命产生重要的影响；同时，由于螺旋输送器结构的特殊性，动平衡工艺在选择及实施方面具有一定的局限性、困难性，进而影响动平衡精度。本文通过对螺旋输送器的动平衡效果进行理论分析，确定影响动平衡效果的关键因素有转子结构形式、转动半径及转速等；并结合动平衡试验过程提出一种优化后的动平衡工艺，主要包括动平衡机的校准、定标、配重位置选择及剩余不平衡量的加重方法等，旨在减小螺旋推进器的剩余不平衡量，提高动平衡精度。最后通过对离心机轴承座温度和振动监测对比，证明该工艺可有效降低离心机整机运行过程中的振动、提高轴承使用寿命。 |

| Abstract:The spiral conveyor is an important component of the rotary system of the horizontal spiral centrifuge. As the only irregular rotary part， it will rotate at a high speed with the rotary system of the centrifuge. Therefore， the dynamic balance precision of the spiral conveyor will have an important impact on the service life of the whole machine. At the same time， because of the particularity of the structure of the spiral conveyor， the selection and implementation of dynamic balancing technology has some limitations and difficulties， which will affect the precision of dynamic balancing. Based on the theoretical analysis of the dynamic balancing effect of the spiral conveyor， the key factors affecting the dynamic balancing effect include the rotor structure， rotation radius and speed， etc.； and in combination with the dynamic balance test process， an optimized dynamic balance process is proposed， mainly including the dynamic balancing machine calibration， benchmarking， selection of counterweight position and the weighting method of residual unbalance， so as to reduce the residual unbalance of the spiral propeller， improve the precision of dynamic balance. Finally， through the monitoring and comparison of the temperature and vibration of the bearing seat of the centrifuge， it is proved that the process can effectively reduce the vibration of the whole centrifuge in working and improve the service life of the bearing. |
