摘　　要：针对42000 m3/h空分设备配套空气增压机主推力轴承温度超标现象,通过增大平衡盘的直径来加大平衡盘的平衡力,抵消叶轮产生的轴向力,进而降低作用在主推力轴承上的剩余轴向力,达到降低主推力轴承温度的目的。简介RBZ45-7型空气增压机的概况和主要技术参数,介绍平衡盘改造的步骤和取得的效果。The temperature of the main thrust bearing of the air booster completed for 42000 m3/h air separation plant exceeds the limit, and the said temperature is lowered through increasing the diameter of the big balancing disk to enlarge the balancing force of the balancing disk, offset the axial thrust generated by the impeller, and further decrease the residual thrust applied onto the main thrust bearing. Here, the outline and main technical parameters of Model RBZ45-7 air booster are briefed, and the reform procedures of the balancing disk and the obtained effects are described.
