The Role of Hydraulic Turbine Main Shaft Seal Ring
The hydraulic turbine main shaft seal ring can play a protective role for the hydraulic turbine, the use of this device can ensure the normal operation of the hydraulic turbine, and it can effectively block the water flow from the gap between the main shaft and the top cover overflow, to prevent the hydraulic turbine guide bearings and the top cover is flooded, to maintain the normal operation of the bearings and units.
Advantages of Hydraulic Turbine Main Shaft Seal Ring
- The main shaft seal ring can effectively prevent the leakage of pressurized water from the rotating part to the fixed part, thus protecting the safe operation of the turbine.
- Hydraulic turbine main shaft seal ring is usually made of wear-resistant materials, which can provide high wear resistance and long life under harsh working conditions.
- The seal ring design allows automatic adjustment when the load changes to maintain good sealing performance.
