Claims

[Scope of utility model registration request]

In an oil drain structure in which bearing boxes are connected between opposing ends of the bearing boxes of a steam turbine by a connecting tube, the oil drain section is
The steam is characterized by creating a pressure difference by connecting the middle part to atmospheric pressure and the inside of the bearing box, which is depressurized by a paper extractor, to create a pressure difference and prevent oil leakage by air flow. Turbine oil drain structure.
