The main functions of hydropower station expansion joints include:
Adjust the flow rate and water head of the turbine water inlet to adapt to different water flow conditions and power generation needs;
Buffer the impact and pressure changes of water flow to protect the turbine and water diversion system from damage;
Reduce vibration and noise in the water flow and improve the stability and operating efficiency of the turbine;
Adapt to the thermal expansion and contraction changes of the water turbine and water diversion system to ensure the normal operation of the system.
The telescopic joint of a hydropower station is usually installed at the connection of the water inlet pipe of the turbine. Through the telescopic design and structure, it can flexibly adjust the flow rate and water head of the water inlet according to changes in water flow conditions and working conditions, ensuring the safe and stable operation of the turbine. In the operation of hydropower stations, hydropower station expansion joints play a very important role and are an indispensable key component in the turbine system.
