          The size of the differential expansion associate with what factors?

          steam turbine at the start, stop and during operation, the size of differential expansion is associate with the following factors:

          ⑴ When starting the unit, the cylinders and flanges use improper means to vote, too large or too small steam heating.

          ⑵ warm-up process, the rate rise too fast or too short warm-up time.

          ⑶when normal shutdown or sliding - parameter shutdown, steam temperature drops too fast.

          ⑷ the load increase too fast.

          ⑸ afterload rejection, empty load or low-load operation for too long.

          ⑹ turbine water impact occurs.

          ⑺ during normal operation, the steam parameters change too fast
