Turbine steam leakage
Thread Content
The air leakage at the shaft seals at both ends of the back-pressure steam turbine is particularly severe, which causes serious emulsification of water in the lubricating oil. However, the negative pressure of the shaft seal exhaust pump remains around -0.03. Does anyone have a solution to this problem?
The steam seal gap should be checked; if the gap is large, the cooling effect of the steam seal cooler is not very effective. Moreover, there are design and manufacturing issues with the steam seals in domestic turbines. Our unit has made appropriate improvements, and the results have been satisfactory.
