Layout and structural characteristics of horizontal machine rent for hydropower station? What are the bearing arrangement characteristics of the horizontal elastic chain connection unit?

The hydraulic turbine spindle and the generator spindle of the horizontal unit are connected elastically, which requires little concentricity of the two shafts and is convenient for installation and maintenance of the unit. It is suitable for small rural power stations with low rotating speed and poor technical strength. When the output of Wozhou Power Station is large and the rotating speed is high, the bearing bush temperature of the unit is too high. After analysis, the solution is put forward. After treatment, the temperature of water guide bearing bush returned to normal and the effect was good. Picture 1.
