What is the main content of power generation steam turbine body inspection?

Inspection of steam turbine body (1) Front casing: indication of total turbine expansion, return oil temperature, return oil volume, vibration conditions, synchronizer position, wheel angle of the oil motor position, if the adjustment valve is blocked and oil motor teeth Are the strips working properly and are they clean? (2) Bearings: oil return temperature, oil volume, vibration conditions of all bearings and possible leakage of the oil damper. (3) Cylinder: shaft seal steam supply, unit operation noise, relative expansion, exhaust cylinder vibration and exhaust steam temperature. (4) Generator and exciter: inlet and outlet air temperature, cooling water pressure, temperature of each cooler, oil pressure of sealing tiles and return oil temperature, volume of oilreturn, possible oil leak in crankcase, internal dual water cooling generator shaft inlet end Water pressure and presence of leaks. (5) Turning equipment: The handle should be placed in the extended position, and the operating power supply should be confirmed to be normal. (6) Automatic main steam valve: indication of the position of the main steam valve and indication of the fluidity of the cooling water. (7) Main dial: pressure and vacuum indication values ​​of steam, water and oil systems, relative expansion difference and axial displacement indication. (8) Hydrogen plate: hydrogen pressure, sealing oil pressure, hydrogen leakage and working conditions of differential pressure valve and balancing valve.
