Wet Cooling Towers are those buildings where the water that was heated by industrial or power generation processes is cooled, again. The heat is given off to the environment. Wet cooling towers are an integral part of the thermodynamic circle.
The water to be cooled is sprayed and distributed over the splash fills. As a result the water temperature drops when the evaporation heat is withdrawn and the air gets humified.
The required air stream for the cooling is produced by ventilators which are mounted on an output shaft of the gear unit. To enable the Flender gear units for power generation and gear units for cooling towers to absorb the enormous ventilation forces the gear units are equipped with an additional axial bearing. Therefore, only application-adapted 2-staged bevel helical gear units are used to fulfill the special requirements of this application.
The motor is installed outside the cooling tower. He is mechanically connected to the gear unit that is placed right in the middle of the diffuser of the cooling tower via long Composite Couplings. These special couplings are also found in the FLENDER product range.
A water turbine is a turbomachine that converts the potential flow energy contained in water into mechanical energy; this mechanical energy is subsequently converted into electrical energy in a generator.
Flender gear units for power generation and water turbines gear up the low turbine speed into a very high generator speed. They also convert the torque that is output by the turbine and transmit it to the generator. The extreme transmission ratio and the high speed result in particularly high loads on the rolling bearings. Flender gear units for water turbines are therefore equipped with bearings of the highest quality in order to reduce friction losses to a minimum.
The mounting position is usually vertical. Flender gear units for power generation feature the proven “dry well” design, which prevents oil leakage and protects the environment.
