        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
