高压热水泵机械密封以及系统改造设计

Reconstruction Design of Mechanical Seals for High Pressure Hot Water Pump

介绍了炼油厂仿制的高压热水泵用波纹管机械密封的失效情况,从仿制参数、冲洗液循环等方面分析了机械密封失效的原因,通过计算验证对此机械密封结构和系统进行了改造,使其性能及使用寿命较仿制密封大大提高。

Failure of bellows mechanical seal used in the pump with the conditions of high pressure and temperature are introduced. The reason was found about parameter , flushing circulation and change the seal construction and system to extend the seal performance and operating life.
