高温油泵波纹管式机械密封故障分析及改进

Failure Analysis and Corrections of Bellows Type Mechanical Seals of High Temperature Oil Pumps

通过对波纹管式机械密封的端面比压和摩擦副环变形分析，说明了热油泵的密封故障是端面比压过低及静环受轴向力变形而引起的．对密封重新选型并改进了结构。

Through analysis on specific pressure of end face and structure of bellows type mechanical seal, the cause of seal failure of the hot oil pumps was seeked,improvements were made and problems were solved.
