摘　　要：针对二氧化碳压缩机高压缸主推力瓦瓦温偏高的问题进行分析,经计算确定直接原因为高压缸残余轴向推力过大,接近推力轴承所能承受的极限。在不改变原推力轴承尺寸的情况下,通过调整膜片联轴器预拉伸量和更换止推瓦块的基体材质等措施,使瓦块的温度降低,效果显著。The overtemperature on CO2 compressor HP cylinder main thrust pad was analyzed. The calculation shows that the direct reason is the excessive residual axial thrust, approaching to the limit. A modifi-cation by adjusting the prestretching force on diaphragm coupling and changing the material of thrust pad without changing the size of original thrust bearing can sharply reduce the temperature.
