Background

The hydraulic turbine is a power machine for converting the energy of water flow into rotary mechanical energy, and belongs to the turbine machinery in fluid machinery. Modern water turbines are mostly installed in hydropower stations and are used for driving generators to generate electricity. In a hydropower station, water in an upstream reservoir is guided to a water turbine through a water guide pipe to push a water turbine runner to rotate so as to drive a generator to generate electricity. The water after doing work is discharged to the downstream through the tail water pipeline. The higher the water head and the larger the flow, the larger the output power of the water turbine is.

Mechanical braking is an important protection means when a unit of a hydraulic power plant is in a shutdown state and the unit creeps. When the unit is in a shutdown state or the unit creeps, the mechanical brake is automatically put into use, and the putting-in and quitting signals of the mechanical brake are fed back through the air brake stroke switch node.
