Simple method for determining oil consumption of water turbine guide bearings

The invention discloses a simple method for determining oil consumption of water turbine guide bearings. The simple method comprises the steps of (1) calculating a dimensionless quantity capacity rotational speed RS according to the known water turbine generator set unit capacity P and the synchronous rotational speed n; (2) investigating and collecting the actual oil consumption of turbine guide bearings of a plurality of power stations; (3) drawing an attached drawing through the calculated capacity rotational speed and scatter point distribution of the actual oil consumption of the turbine guide bearings of all the power stations and a trend line fitted according to scatter points, and quickly determining the oil consumption of the turbine guide bearings according to the attached drawing. By means of the method, through the two known general parameters, the oil consumption of the turbine guide bearings is quickly determined after simple calculations. Earlier-stage calculation work of the oil consumption of
