【 摘 要 】

In the commissioning of power plant, this paper finds that the shaft seal pressure of small steam turbine does not match the shaft seal pressure of steam turbine, and the shaft seal pressure of small steam turbine is high. On the basis of on-site verification and theoretical calculation, the problem of abnormal shaft seal pressure of small steam turbines was solved by modifying the steam turbine shaft sealing point access point and increasing the small turbine shaft seal overflow device, which provided a solution for similar problems in the future.
