FGD外围泵机械密封结构特点

Unique Feature Analysis on the FGD Periphery Pump Mechanical Seal

介绍了烟气脱硫装置(FGD)流程和FGD外围泵机械密封使用条件,从结构型式分析了无内冲洗水单端面机械密封、带压内冲洗水单端面机械密封、带阻封液的双端面机械密封在应用中的各自特点及寿命。

FGD process and conditions of Use for FGD periphery pumps mechanical seals were introduced. According to the structure pattern, respective characteristic and the life discussion in the application were analyzed, includes, the internal without a liquid flushing fluid single mechanical seals, the internal have a liquid flushing fluid with pressure single mechanical seals, and the internal with a liquid barrier fluid double mechanical seals.
