What are full umbrella and half umbrella hydrogenerators

Introduction What are full umbrella and half umbrella hydrogenerators? Full umbrella hydrogenerators may have top guide bearings or no top guide bearings. If the umbrella turbine generator does not have a lower guide bearing, it is equivalent to

What are full umbrella and half umbrella hydrogenerators

The complete umbrella hydrogenerator may have an upper guide bearing or not. If the umbrella turbine generator does not have a lower guide bearing, it is equivalent to simply holding the umbrella without grasping it when opening the umbrella. This is a semi-umbrella turbine generator.

Hydraulic generator refers to a generator that uses a hydraulic turbine as the prime mover to convert water energy into electrical energy. As water flows through the turbine, the energy of the water is converted into mechanical energy. The rotating shaft of the turbine drives the generator rotor, which converts mechanical energy into electrical energy and produces it. It is the main electrical equipment for producing electrical energy in hydroelectric power stations.

A hydrogenerator is driven by a water turbine. Its rotor is short and thick, the unit starts and connects to the rebucket in a short time and the operating program is flexible. In addition to general electricity generation, it is particularly suitable as a peak shaving unit and as an emergency backup unit. . The maximum capacity of the hydrogenerator unit reached 800,000 kilowatts.

Diesel generators are driven by internal combustion engines. It starts quickly and is easy to use, but the cost of generating electricity is high. It is mainly used as emergency backup power, or used in areas and mobile power stations that are not accessible by large power grids. Capacity is typically between a few kilowatts and several thousand kilowatts. The output torque on the diesel engine shaft pulses periodically, so resonance and shaft breakage accidents should be avoided.
