Working principle of steam turbine What is the working principle of steam turbine?

1, working principle: including the working principle of steam turbine stage and the working principle of the whole steam turbine unit. The working principle of steam turbine involves the flow of steam, the generation and loss of force on blades, and the method of adapting the steam turbine to the change of external load.

2. When the steam turbine starts, stops and runs, the cylinder temperature changes greatly, and it will expand or contract along the length, width and height directions. Because the temperature rise of the foundation bedplate is lower than that of the cylinder, if the cylinder is fixedly connected with the foundation bedplate, the cylinder will not expand freely, so the cylinder should be provided with a sliding pin system to solve the problem of free expansion in the operation of the steam turbine.

3. Sliding pin system usually consists of horizontal pin, vertical pin, vertical pin and corner pin.
