增速机径向瓦超温原因分析及改进措施

摘要

Analyze the cause of speed-up machine radial tile overtemperature in the ASU three-in-one unit ,propose the improvement measures included increasing the feed oil temperature ,expanding up the bearing clearance and enlarging oil cooler heat exchanger surface ,etc . T hen the speed-up machine operates stably .%针对空分装置三合一机组的增速机径向瓦超温严重的问题，分析其原因，并提出提高供油温度、扩大轴瓦间隙、加大油冷却器换热面积等改进措施，实现了增速机的平稳运行。
