汽轮机汽缸密封脂是用于发电厂汽轮机本体结合面的密封剂,可起到辅助密封的作用。随着火电厂汽轮机组蒸气参数从低压机组向中压、高压、超高压、亚临界、超临界机组和超超临界机组的不断提升,汽轮机汽缸密封脂的性能指标也不断提高。详细介绍了汽轮机汽缸密封脂的发展阶段,简单介绍了MFZ系列汽轮机汽缸密封脂的性能指标,并指出了现阶段汽轮机汽缸密封脂存在的问题及今后的发展方向。
Turbine cylinder sealing grease is used in power plant turbine body sealing surface sealant, can play a supporting role of the seal. As the steam turbine steam turbine power plant parameters from low pressure unit to medium pressure, high pressure, high pressure, subcritical, supercritical units and ultra-supercritical unit continues to improve, the performance of steam turbine cylinder sealing grease also continue to improve. This paper introduces the development phase of steam turbine cylinder sealing grease in detail, briefly introduces the performance of MFZ series turbine cylinder sealing grease, and points out the existing problems and future development trends of steam turbine cylinder sealing grease.
