Steam turbine in use can produce relatively large energy, can be used in power generation, compared with the general generator set, power generation efficiency is higher, and less energy consumption, in the whole turbine accessories, what is the use of the coupling?
The coupling of small steam turbine can be divided into rigid coupling, semi-flexible coupling and flexible coupling.
1. Rigid coupling: advantages are simple structure, small size, low cost, no need for lubricating oil.
2. Semi-flexible coupling: the advantage is that it can properly compensate the shortcomings of the rigid backrest wheel, and the school center is slightly lower.
3. Flexible coupling: the advantage is that the rotor oscillation and thermal expansion do not transfer to each other, allowing two turbine rotor center line slightly deviation. In general, rigid coupling is used between high and low pressure rotors of large units, and semi-flexible coupling is used between low pressure rotors and generator rotors.
In the steam turbine, its coupling can be said to have a good use in the whole equipment, we can make good use of their use, do some power generation operations, coupling this part is very important, and need to be replaced on time.
