摘　　要：简述了混炼机转子密封的特点，分析了该机组运行中密封失效的主要原因为转子径向受力过大，使转子偏心度增加。通过将转子两端螺旋密封的温度控制在130℃±5℃，并控制树脂温度为180℃±5℃等措施，有效地解决了该机组密封泄漏的问题。The characteristic of the seal for rotor of mixing mill is briefly explained. The major causes of seal failure are found. It is clear that the axial force acting on rotor is big enough to create additional eccentricity of rotor. To solve the problem the helical seal＇s temperatures at both ends of rotor are controlled between 130 ℃ ±5 ℃ and the temperatures of resin between 180℃±5 ℃ and so on. Now the unit＇s seal failure is under effective control.
