The T540 steam turbine is a single - stage back - pressure steam turbine. It is equipped with a velocity-compounded stage impeller, with the impeller pitch - circle diameter being 1040 millimeters. The rotational speed of the main shaft ranges from 1500 to 4500 revolutions per minute, and the power range is from 200 to 2500 KW. A gearbox can be installed as per user requirements to achieve speed variation. The main feature of this model is to utilize steam ranging from low-temperature and low - pressure to sub - high - temperature and sub-high-pressure as the steam source to drive rotating machinery for work, thus realizing the cascade utilization of energy and achieving the goal of energy conservation and consumption reduction.

Emergency Shut-off Device
The emergency shut-off device is a protective mechanism that prevents the rotor from exceeding the allowable rotational speed, installed on the main oil pump casing connected to the main shaft. The emergency shut-off device used in this unit is a centrifugal flyweight type, which has an eccentric weight mounted radially on the main oil pump casing. At normal rotational speeds, a spring force balances it. When the unit's speed exceeds the rated speed by 9-11%, the flyweight is thrown out, causing the emergency shut-off throttle to disengage and activate.
